DETAILED DESCRIPTION OF THE INVENTION

(16) In FIGS. 1 and 2 a plug connector 50 is shown, which is embodied by a plug socket. The plug connector 50 is embodied as an RJ plug connector. The plug connector 50 is embodied as an RJ45 plug connector. It is however also conceivable that the plug connector 50 is embodied, for example, as an RJ11 plug connector or in another way that is deemed expedient by a person having ordinary skill in the art. The plug connector 50 is provided for corresponding with a data plug and for establishing in a plugged-in state of the data plug a data network connection. The plug connector 50 comprises a plug connector device 10 with a housing 38, a wiring block 12, a contact element 36 and a wiring cover 40 as well as a plug contact unit 52 and an intermediary housing 54. The plug connector device 10 is provided for receiving and fixating a multi-wire data cable 14. The multi-wire data cable 14 comprises eight wires 18 and a drain wire. However, an alternative data cable would also be conceivable, in which the drain wire is dispensed with. The data cable 14 may also comprise another number of wires 18, which is deemed expedient by a person having ordinary skill in the art. The wires 18 of the data cable 14 are pair-wise twisted with each other. The wires 18, which are arranged and twisted with each pair-wise, are encompassed by a wire-pair shielding, which is not shown. The wire-pair shielding is implemented by a foil in which the wires 18 are wrapped, which are arranged and twisted with each other in pairs. The wire-pair shielding is implemented of metal. The wire-pair shielding is implemented by a metal foil. The wire-pair shielding may in addition also be implemented at least partially of plastic. However, an alternative data cable is also conceivable, in which the wire-pair shielding is dispensed with. The drain wire runs approximately centrally in the data cable 14 between the wires 18, which are arranged and twisted with each other in pairs, and contacts the wire-pair shielding of the wires 18 of the data cable 14, which are pairwise arranged and twisted with each other. The data cable 14 may also comprise an exterior shielding. The data cable 14 further comprises an insulation encompassing in a circumferential direction the wires 18, which are arranged and twisted with each other in pairs, the wire-pair shielding of the latter, the drain wire and, if applicable, the exterior shielding.

(17) The plug contact unit 52 comprises a first plug contact zone 56 which, in a plugged-in state of the data plug in the plug connector 50, establishes an electric contact directly between the data plug and the plug connector 50, and comprises a second plug contact zone 58, which in an assembled state of the plug connector 50 establishes an electric contact to wires 18 of the multi-wire data cable 14 that is coupled to the plug connector 50. In the first plug contact zone 56 of the plug contact unit 52 contact wires 60 are arranged which, in a plugged-in state of the data plug in the plug connector 50, are in a direct electric contact with the data plug. The first plug contact zone 56 comprises eight contact wires 60. The second plug contact zone 58 of the plug contact unit 52 comprises insulation displacement contacts 62 (IDC) which, in an assembled state of the plug connector 50, are in direct electric contact with the wires 18 of the multi-wire data cable 14. The plug contact unit 52 comprises eight insulation displacement contacts 62. However, a different number of the contact wires 60 and/or of the insulation displacement contacts 62, which is deemed expedient by a person having ordinary skill in the art, is also conceivable. The plug contact unit 52 further comprises a connection board 64, which is arranged between the first plug contact zone 56 and the second plug contact zone 58 and via which the contact wires 60 and the insulation displacement contacts 62 are electrically connected.

(18) The intermediary housing 54 is implemented of a plastic material. In an assembled state of the plug connector 50, the intermediary housing 54 partly encloses the wiring block 12 and the plug contact unit 52. The housing 38 is provided for at least partly enclosing the wiring block 12 in an assembled state. The housing 38 partly encloses the plug connector device 10 as well as the plug contact unit 52, the contact element 36 and the intermediary housing 54 in a circumferential direction and partly forms an exterior surface of the plug connector 50. The housing 38 is made of a plastic material. As an alternative or additionally, however, other materials are also conceivable for the housing 38, which are deemed expedient by a person having ordinary skill in the art. The housing 38 has a shielding effect against in-coupling and out-coupling electric and/or magnetic fields, which is implemented in a shielded version of the housing 38 by means of the metallic housing 38 itself, and in an unshielded version (not shown) of the housing by means of an integrated metallic shielding foil. In said not shown, unshielded version it is also conceivable to realize the shielding foil by a plastics material reinforced with metal fibers or by another material that is deemed expedient by a person having ordinary skill in the art.

(19) The wiring block 12 of the plug connector device 10 is provided for receiving the multi-wire data cable 14 (FIGS. 4 to 6). The plug connector device 10 may however also be provided for receiving two or more data cables 14. The wiring block 12 comprises a guiding element 66, which is provided for receiving and guiding the data cable 14. The guiding element 66 has a circular cross section. The guiding element 66 is embodied as a cylindrical recess. The guiding element 66 has a diameter of 9.5 mm. However, other measurements of the diameter of the guiding element 66, which are deemed expedient by a person having ordinary skill in the art, are also conceivable. For receiving data cables 14 having a substantially smaller diameter than the guiding element 66, a diameter-reducing element 84 can be inserted in the guiding element 66. The diameter-reducing element 84 is implemented as an accessory component that is embodied separately from the wiring block 12. The diameter-reducing element 84 is implemented in such a way that it can be releasably coupled to the guiding element 66. The diameter-reducing element 84 has a circular outer cross-sectional contour. The diameter-reducing element 84 has a cylinder-shaped outer contour. The diameter-reducing element 84 has an outer diameter of 9.5 mm. Further the diameter-reducing element 84 comprises four lamella elements (not shown). The lamella elements are elastically deformable. When the data cable 14 is introduced, the lamella elements are pushed outwards in an elastically resilient fashion, thus holding the data cable 14 in a force-fit manner.

(20) The wiring block 12 of the plug connector device 10 comprises at least one receiving region 16 for receiving the wires 18 of the data cable 14. The wiring block 12 comprises a plurality of receiving regions 16 for receiving the wires 18 of the data cable 14. The wiring block 12 comprises eight receiving regions 16 for receiving the wires 18 of the data cable 14. The wiring block 12 is embodied of an electrically insulating material. The wiring block 12 is made of plastic. As an alternative or additionally, however, other materials deemed expedient by a person having ordinary skill in the art are also conceivable for the wiring block 12. The wiring block 12 of the plug connector device 10 comprises at least one at least partly deformable receiving element 20 for receiving the wires 18 of the data cable 14. The wiring block 12 comprises a plurality of receiving elements 20 for receiving the wires 18 of the data cable 14. The wiring block 12 comprises eight receiving elements 20 for receiving the wires 18 of the data cable 14. The receiving regions 16 of the wiring block 12 are at least partly delimited by at least one of the at least partly deformable receiving elements 20. The receiving regions 16 of the wiring block 12 are respectively delimited by one of the receiving elements 20. The receiving elements 20 are embodied in a one-part implementation with the wiring block 12. The receiving elements 20 and the wiring block 12 are produced in an injection-molding process.

(21) Each of the receiving elements 20 comprises a first receiving piece 22 and a second receiving piece 24. The receiving element 20 is composed of the first receiving piece 22 and the second receiving piece 24. The first receiving piece 22 and the second receiving piece 24 of the receiving element 20 respectively form a partial region of the receiving element 20. The first receiving piece 22 and the second receiving piece 24 of the receiving element 20 delimit the receiving region 16 on two sides situated, if viewed in a radial direction 34 of the data cable 14, opposite each other. The first receiving piece 22 and the second receiving piece 24 of the receiving element 20 are arranged spaced apart if viewed in a radial direction of the data cable 14.

(22) The first receiving piece 22 is embodied at least partly elastically deformable. The first receiving piece 22 is embodied at least partly lamellar. The first receiving piece 22 of the receiving element 20 comprises two lamellae 68, which are situated opposite each other and are embodied deformable. The lamellae 68 of the first receiving piece 22 of the receiving element 20 have a low material thickness. The lamellae 68 of the first receiving piece 22 have, viewed towards the wiring block 12, a decreasing distance. A smallest distance between the lamellae 68 of the first receiving piece 22 is shorter than a thickness, respectively diameter, of one of the wires 18 of the data cable 14.

(23) The second receiving piece 24 is embodied at least partly elastically deformable. The second receiving piece 24 comprises at least one holding lug 26, which is provided at least partly for a force-fit and form-fit fixation of respectively one of the wires 18 of the data cable 14. The second receiving piece 24 of the receiving element 20 comprises two lamellae 88 arranged opposite each other and respectively having a holding lug 26, which are provided for a force-fit and form-fit fixation of respectively one of the wires 18 of the data cable 14. The lamellae 88 of the second receiving piece 24 of the receiving element 20 have a low material thickness. The lamellae 88 of the second receiving piece 24 have, viewed towards the wiring block 12, a decreasing distance. A smallest distance between the lamellae 88 of the second receiving piece 24 is shorter than a thickness respectively a diameter of one of the wires 18 of the data cable 14. The holding lugs 26 of the second receiving piece 24 have a smallest distance from each other which is shorter than the thickness respectively the diameter of one of the wires 18 of the data cable 14. The first receiving piece 22 and the second receiving piece 24 of the receiving element 20 are embodied having different rigidities. The first receiving piece 22 of the receiving element 20 is embodied at least partly more rigid than the second receiving piece 24 of the receiving element 20.

(24) Due to the decreasing distance between the lamellae 68, 88 of the first receiving piece 22 and the second receiving piece 24, and to the elastic deformability of the first receiving piece 22 and the second receiving piece 24, wires 18 with different diameters can be reliably received and held.

(25) In an assembly of the plug connector device 10, the data cable 14 is stripped in a first step. Then the stripped section of the data cable 14 is slid into the guiding element 66 of the wiring block 12 until an edge of the insulation of the data cable 14, which is still arranged on the data cable 14, abuts at least one stop element 80 of the wiring block 12, as a result of which the stripped section of the data cable 14 is arranged on a side of the guiding element 66 that faces the receiving regions 16 of the wiring block 12. The wiring block 12 comprises two stop elements 80 arranged on walls of the guiding element 66 which are situated opposite each other along a diameter of the guiding element 66. The stop elements 80 are embodied in a one-part implementation with the wiring block 12. The stop elements 80 protrude into the guiding element 66 of the wiring block 12 in a radial direction 34 of the data cable 14. The stop elements 80 are embodied rib-shaped. The stop elements 80 are furthermore provided for supporting and facilitating a threading-in or inserting of the stripped section of the data cable 14 while dividing up the pairwise arranged wires 18 approximately equally into two groups and thus pre-sorting the pairwise arranged wires 18.

(26) In a slid-in state of the data cable 14 the pairwise twisted wires 18 of the data cable 14 are undone in the stripped section of the data cable 14 and are then each introduced into one of the receiving elements 20 separately. Respectively one wire 18 of the data cable 14 is introduced into respectively one of the receiving elements 20 perpendicularly to an introduction direction 70 of the data cable 14. For this purpose the wires 18 are, viewed in parallel to the introduction direction 70, inserted into the first receiving piece 22 and the second receiving piece 24 from above, and are pressed towards the wiring block 12 into the receiving elements 20. Herein the wire 18 is pressed between the lamellae 68 of the first receiving piece 22 of one of the receiving elements 20, as a result of which the lamellae 68 are deformed and fixate the wire 18 of the data cable 14 in a force-fit and form-fit fashion. The lamellae 68 of the first receiving piece 22 and the lamellae 88 of the second receiving piece 24 of one of the receiving elements 20 deform elastically. It is however also conceivable that, when the wire 18 of the data cable 14 is pressed in, the lamellae 68 of the first receiving piece 22 and the lamellae 88 of the second receiving piece 24 of one of the receiving elements 20 deform plastically or additionally rupture partly, the ruptured lamellae 68, 88 hooking into an insulation of the wire 18 of the data cable 14 and a particularly reliable fixation of the wire 18 of the data cable 14 being thus achievable. It is moreover also conceivable that the lamellae 68 of the first receiving piece 22 and the lamellae 88 of the second receiving piece 24 of the receiving elements 20 are embodied at least partly knife-like, as a result of which the lamellae 68 of the first receiving piece 22 and the lamellae 88 of the second receiving piece 24 at least partly cut into the insulation of the wires 18 in an inserted state. The lamellae 68 of the first receiving piece 22 and the lamellae 88 of the second receiving piece 24 partly cut into the insulation of the wires 18 in an inserted state, thus achieving a form-fit fixation of the wires 18. The lamellae 68 of the first receiving piece 22 and the lamellae 88 of the second receiving piece 24 are implemented sharp-edged and knife-shaped.

(27) Further, when pressed into the receiving elements 20, the wires 18 are, viewed in parallel to the introduction direction 20, respectively inserted into the second receiving piece 24 from above and are pressed towards the wiring block 12 into the receiving elements 20, in such a way that the wire 18 is pressed between the space between the holding lugs 26 of the second receiving piece 24 of the receiving elements 20 and come to lie in a receiving region of the second receiving piece 24. The holding lugs 26 of the second receiving piece 24 secure the wire 18 of the data cable 14 against slipping out into the introduction direction 70 of the data cable 14. It is also conceivable that, alternatively or additionally, the first receiving piece 22 of the receiving elements 20 respectively comprise at least one holding lug. The wires 18 are cut off laterally flush with the wiring block 12 by means of a tool.

(28) Then the wiring block 12 and the plug contact unit 52 are slid together in parallel to the introduction direction 70 of the data cable 14 in such a way that the insulation displacement contacts 62 of the second plug contact zone 58 of the plug contact unit 52 contact the wires 18 of the data cable 14 (FIG. 9). Respectively one of the insulation displacement contacts 62 engages in the slid-together state into respectively one depression, which is respectively encompassed by one of the receiving regions 16 and is, viewed in a radial direction 34, arranged between the first receiving piece 22 and the second receiving piece 24 of one of the receiving elements 20. Respectively one of the insulation displacement contacts 62 engages in the slid-together state into a wire 18 of the data cable 14, cutting into the insulation of the wire 18 of the data cable 14, as a result of which the insulation displacement contact 62 electrically contacts the wire 18. When sliding together and the insulation displacement contacts 62 cutting into the insulation of the wires 18 of the data cable 14, the wires 18 of the data cable 14 are respectively held by the first receiving piece 22 and the second receiving piece 24 of the receiving elements 20 and are secured against the wires 18 slipping off during the sliding together. By way of such double positioning of the wires 18 respectively by the first receiving piece 22 and the second receiving piece 24 of the receiving elements 20, an advantageously precise and constant wiring quality can be achieved via the insulation displacement contacts 62.

(29) To prevent a slipping out of the data cable 14 in assembly of the wiring block 12, the plug connector device 10 comprises a strain relief unit 46 arranged on the wiring block 12, which is provided for fixating the data cable 14 in an assembly state with respect to the wiring block 12 in a force-fit fashion (FIG. 7). It is however also conceivable that the strain relief unit 46 is provided for fixating the data cable 14, as an alternative or additionally, in a form-fit manner. The strain relief unit 46 is arranged directly or indirectly on the wiring block 12. The strain relief unit 46 comprises a strain relief element 48 and a fixation element. The strain relief element 48 is implemented by a metal sheet. The strain relief element 48 is implemented groove-shaped. The strain relief element 48 is implemented trough-shaped. The strain relief element 48 has a pitch-circle shaped cross-section. However, other implementations of the strain relief element 48 deemed expedient by a person having ordinary skill in the art are also conceivable, e.g. with a V-shaped cross-section. The fixation element is embodied by a cable tie (FIG. 10). However, other implementations of the fixation element deemed expedient by a person having ordinary skill in the art are also conceivable.

(30) For fixating the data cable 14 the data cable 14 is guided along the strain relief element 48 and is then firmly strapped and fixated by means of the fixation element that engages around the strain relief element 48 and the data cable 14. The strain relief unit 46 is provided for fixating the data cable 14 in at least one position with respect to the wiring block 12. The strain relief unit 46 is provided for fixating the data cable 14 in at least two orientations that differ by at least 45 degrees with respect to the wiring block 12. The strain relief unit 46 is provided for fixating the data cable 14 in two orientations that differ by 90 degrees with respect to the wiring block 12. The strain relief element 48 of the strain relief unit 46 is fixedly connected to the wiring block 12. The strain relief element 48 of the strain relief unit 46 is connected to the wiring block 12 in a form-fit fashion. As an alternative or additionally, it is however also conceivable that the strain relief element 48 is connected to the wiring block 12 by substance-to-substance bond or in a force-fit fashion. The strain relief element 48 of the strain relief unit 46 can be brought by a plastic deformation, e.g. bending by an operator, into the two orientations that differ by 90 degrees with respect to the wiring block. It is also conceivable to bring the strain relief element 48 of the strain relief unit 46 into orientations differing with respect to the wiring block 12 by another angle measurement, e.g. 30 degrees, 45 degrees or 60 degrees, via a plastic deformation.

(31) As an alternative it is also conceivable that the strain relief element 48 of the strain relief unit 46 is connected to the wiring block 12 releasably. The strain relief element 48 of the strain relief unit 46 can be connected to the wiring block 12 in such a way that it is toollessly releasable. The strain relief element 48 of the strain relief unit 46 may in an assembled state be inserted in a strain relief element receptacle 82, which is introduced into the wiring block 12.

(32) Moreover the strain relief element 48 of the strain relief unit 46 may be provided to be fixated in one of in total four orientations which differ by 90 degrees and are arranged in an assembled state distributed around the data cable 14 (FIG. 8, depicted by dashed line). For this purpose four strain relief element receptacles 82 are provided on the wiring block 12, which are embodied slot-shaped and in which the strain relief element 48 can be inserted. However, another number of strain relief element receptacles 82 on the wiring block 12, e.g. one, two, three or more, are also conceivable. The strain relief element receptacles 82 are arranged, in an axial view direction, at 3 o'clock, 6 o'clock, 9 o'clock and 12 o'clock. In a delivery status of the plug connector device 10, the strain relief element 48 of the strain relief unit 46 is arranged on the wiring block 12 in the strain relief element receptacle 82, in an axial view direction, at 6 o'clock. However, other arrangements of the strain relief element receptacles 82 on the wiring block 12 deemed expedient by a person skilled in the art are also conceivable. It is however also conceivable that, in one of the orientations differing in a circumferential direction, the strain relief element 48 of the strain relief unit 46 is fixedly connected to the wiring block 12.

(33) It is furthermore also conceivable that the strain relief element 48 of the strain relief unit 46 is embodied in such a way that it is fixable on the wiring block 12 in at least two orientations differing by at least 45 degrees with respect to the wiring block 12. The strain relief element 48 of the strain relief unit 46 may be embodied in such a way that it is fixable on the wiring block 12 in two orientations differing by 90 degrees with respect to the wiring block 12. The strain relief element 48 can be embodied in such a way that it can be releasably connected to the wiring block 12. The strain relief element 48 can be embodied in such a way that it can be releasably connected to the wiring block 12 toollessly. The wiring block 12 can comprise at least two strain relief element receptacles 82, which are pairwise introduced in two sides of the wiring block 12 which are angled by at least 90 degrees. The strain relief element receptacles 82 are embodied slot-shaped. The strain relief element 48 is insertable into the strain relief element receptacles 82.

(34) The wiring block 12 further comprises a drain wire receptacle element 28, which is provided for receiving a drain wire of the data cable 14 (FIG. 6). The drain wire receptacle element 28 is embodied groove-shaped. The drain wire receptacle element 28 is embodied trough-shaped. The drain wire receptacle element 28 has a pitch-circle shaped cross section. The drain wire receptacle element 28 is embodied in a one-part implementation with the wiring block 12. The drain wire receptacle element 28 is arranged at least partly on an exterior side 30 of the wiring block 12. The drain wire receptacle element 28 is provided for guiding the drain wire at least partly in an axial direction 32 and in a radial direction 34. The axial direction 32 extends in parallel to the introduction direction 70 of the data cable 14. The drain wire receptacle element 28 extends, viewed in parallel to the introduction direction 70 of the data cable 14, from a side of a wall of the wiring block 12 facing the receiving elements 20 towards and along the exterior side 30 of the wall of the wiring block 12 and then, viewed in parallel to the introduction direction 70 of the data cable 14, along a side of a wall of the wiring block 12 facing away from the receiving elements 20. The drain wire receptacle element 28 is embodied U-shaped if viewed in a main extension direction of the drain wire receptacle element 28.

(35) In assembly the drain wire is guided by the guiding element 66, in which the data cable 14 is held, to the drain wire receptacle element 28 and is placed in the drain wire receptacle element 28 that is embodied groove-shaped and is guided in the drain wire receptacle element 28. In the drain wire receptacle element 28 the drain wire is guided U-shaped around a wall of the wiring block 12. By this arrangement of the drain wire receptacle element 28, a contacting of the drain wire after a short length of the drain wire and thus good shielding characteristics are achievable.

(36) The plug connector device 10 further comprises the contact element 36, which is provided for electrically contacting the drain wire received in the drain wire receptacle element 28 (FIGS. 9 to 11). The contact element 36 is implemented of an electrically conductive material. The contact element 36 is implemented of a metal. The contact element 36 is implemented of a metal sheet. In an assembled state the contact element 36 covers part of the drain wire receptacle element 28 and contacts the drain wire guided in the drain wire receptacle element 28. The contact element 36 comprises a first region 72 contacting in an assembled state the drain wire, and comprises at least one second region 74, which is provided for directly contacting the data plug in a plugged-in state. The contact element 36 comprises two second regions 74. The second regions 74 of the contact element 36 are arranged in parallel. The second regions 74 of the contact element 36 are embodied L-shaped. The second regions 74 of the contact element 36 are implemented angled with respect to the first region 72 of the contact element 36. The second regions 74 of the contact element 36 are embodied angled by respectively 90 degrees with respect to the first region 72 of the contact element 36. The second regions 74 of the contact element 36 are arranged subsequently to the first region 72 of the contact element 36 on opposite sides of the first region 72 of the contact element 36. The contact element 36 partly encompasses the plug contact unit 52, the intermediary housing 54 and the wiring block 12. A portion of the first region 72 which faces away from the wiring block 12 and the second regions 74 of the contact element 36 partly engage around the first plug contact zone 56. The portion of the first region 72 facing away from the wiring block 12, and the second regions 74 of the contact element 36 engage around the first plug contact zone 56 in a U-shaped fashion. The contact element 36 is in an assembled state enclosed by the housing 38. The contact element 36 is embodied separate from the housing 38. It is however also conceivable that the contact element 36 is embodied at least partly or completely in a one-part implementation with the housing 38, and/or that the housing 38 is implemented at least partly or completely of an electrically conductive material, e.g. of a metal or a conductive plastics material.

(37) The plug connector device 10 further comprises the wiring cover 40, which is pivotably supported at the housing 38 (FIG. 3). The wiring cover 40 is embodied in such a way that it is releasable from the housing 38 in a folded-open state. The wiring cover 40 is supported at the housing pivotably about an axis which runs perpendicularly to the introduction direction 70 of the data cable 14. The wiring cover 40 is embodied in a shielded version (not shown) of a metal and in an unshielded version of a plastics material. As an alternative or additionally, other materials deemed expedient by a person skilled in the art are also conceivable for the wiring cover 40, e.g. an electrically and/or magnetically shielding plastics material, which in particular comprises metal fibers but is not embodied electrically conductive, as a result of which a shielding effect against in-coupling and out-coupling electric and/or magnetic fields is achievable. It is moreover also conceivable that the wiring cover 40 comprises a shield embodied as a metal foil. The wiring cover 40 further comprises a supporting element 42, which is provided for pivotably supporting the wiring cover 40 at the housing 38 and which comprises at least one collar 44. The wiring cover 40 comprises two supporting elements 42. The supporting elements 42 of the wiring cover 40 are embodied as supporting bolts. The supporting elements 42 are embodied in a one-part implementation with the wiring cover 40. The supporting elements 42 respectively comprise the one collar 44. The collar 44 is respectively embodied disk-shaped. The collar 44 has a greater diameter than the respective supporting element 42. The collar 44 and the supporting element 42 have the same rotary axis. The collar 44 and the supporting element 42 are embodied in a one-part implementation. The wiring cover 40 comprises at least one conversion element 76, which is provided for at least partially converting a pivoting movement of the wiring cover 40 into a translatory movement. The conversion element 76 is provided for at least partially converting the pivoting movement of the wiring cover 40 into a translatory movement of the wiring block 12 towards the plug contact unit 52. The conversion element 76 is provided for transferring a force onto the wiring block 12 by way of a pivoting movement of the wiring cover 40. The wiring cover 40 comprises two conversion elements 76. Respectively one of the conversion elements 76 of the wiring cover 40 is arranged on a side of the collar 44 which respectively faces away from the supporting element 42. The collar 44 and the respective conversion element 76 are embodied in a one-part implementation. The conversion element 76 is embodied as a slotted-link guide.

(38) For assembly the wiring cover 40 is slid into a slot-shaped receptacle 78 of the housing 38 perpendicularly to the introduction direction 70 of the data cable 14 and is then pivoted about the rotary axis of the supporting elements 42. Herein the collars 44 of the supporting elements 42 engage behind the receptacle 78 that is introduced in the housing 38 and can, in the pivoting movement of the wiring cover 40, prevent lateral regions of the wiring cover 40, on which the supporting elements 42 are arranged, from bending out. Due to the pivoting movement the wiring block 12 is pressed towards the plug contact unit 52 and the pivoting movement is thus converted into a translatory movement of the wiring block 12 via the conversion elements 76. Herein the insulation displacement contacts 62 engage into the receiving regions 16 of the wiring block 12 while cutting into the insulation of the wires 18 of the data cable 14, and are thus brought into electric contact to the wires 18 of the data cable 14.

(39) As an alternative, it is also conceivable that the wiring cover 40 is implemented at least partly of a metal or is implemented reinforced at least in a region of the supporting elements 42, as a result of which a bending open of the wiring cover 40 in the pivoting movement of the wiring cover 40 can be prevented due to a high stability of the wiring cover 40 and the collar 44 can hence be dispensed with.

(40) In FIGS. 12 and 13 a further exemplary embodiment of the invention is shown. The following description and the drawings are essentially limited to the differences between the exemplary embodiments, wherein regarding identically designated structural components, in particular regarding structural components having the same reference numerals, principally the drawings and/or the description of the other exemplary embodiment, in particular FIGS. 1 to 11, may be referred to. For distinguishing between the exemplary embodiments, the letter a is set subsequently to the reference numerals of the exemplary embodiment in FIGS. 12 and 13.

(41) In FIGS. 12 and 13 a further implementation form of a strain relief unit 46a of a plug connector device 10a is shown. The plug connector device 10a largely corresponds to the plug connector device 10 described above. The strain relief unit 46a is provided for preventing a data cable 14a from slipping out when a wiring block 12a of the plug connector device 10a is assembled. The strain relief unit 46a is provided for fixating the data cable 14a in an assembly state with respect to the wiring block 12a in a force-fit and/or form-fit manner. The strain relief unit 46a comprises a strain relief element 48a. The strain relief element 48a is implemented of plastic. An implementation of the strain relief element 48a of a metal sheet or metal cast, but also as a metal component around which plastics material has been injection-molded is also conceivable. The strain relief element 48a of the strain relief unit 46a is embodied as a holding strap. The strain relief element 48a of the strain relief unit 46a is fixated to the wiring block 12a of the plug connector device 10a. The strain relief element 48a of the strain relief unit 46a is releasably fixated to the wiring block 12a of the plug connector device 10a. The strain relief element 48a of the strain relief unit 46a is fixated to the wiring block 12a in a form-fit manner. The strain relief element 48a is fixated to a fixation element 90a, which is arranged on the wiring block 12a of the plug connector device 10a. The fixation element 90a is embodied pin-shaped. However other implementations of the fixation element 90a, which are deemed expedient by a person having skill in the art, are also conceivable. The strain relief element 48a is supported pivotably about the fixation element 90a. The strain relief element 48a is releasably connected to the fixation element 90a of the wiring block 12a.

(42) The strain relief element 48a of the strain relief unit 46a comprises an abutment surface 92a, which in an assembled state abuts an insulation of the data cable 14. The strain relief element 48a comprises radial ribs on the abutment surface 92a, which establish a form-fit connection to the data cable 14a. The strain relief element 48a of the strain relief unit 46a comprises a latching region, which is situated opposite the abutment surface 92a and comprises a plurality of latch teeth 94a. The latch teeth 94a are embodied corresponding to at least one latch element 96a, 98a, which is arranged on the wiring block 12a of the plug connector device 10a. The wiring block 12a comprises two latch elements 96a, 98a. The latch elements 96a, 98a are, viewed in a latching direction of the strain relief element 48a, arranged subsequently to each other and spaced apart.

(43) In an assembled state the strain relief element 48a engages around the data cable 14a and is securely strapped. A form-fit and/or force-fit connection retain/retains the data cable 14a in the intended space permanently. For fixating a data cable 14a having a large diameter, the latch teeth 94a of the strain relief element 48a of the strain relief unit 46a correspond to the first latch element 96a and latch with said first latch element 96a until the data cable 14a is secured against slipping off with respect to the strain relief element 48a in a force-fit and/or form-fit fashion. The latching connection between the latch teeth 94a of the strain relief element 48a of the strain relief unit 46a and the latch elements 96a, 98a of the wiring block 12a is implemented in such a way that it is releasable. For the purpose of releasing the latching connection between the latch teeth 94a of the strain relief element 48a of the strain relief unit 46a and the latch elements 96a, 98a of the wiring block 12a, the strain relief element 48a is pressed inwards through an opening that is arranged between the first latch element 96a and the second latch element 98a of the wiring block 12a, and is thus put into operation. The strain relief element 48a is pressed inwards through the opening between the first latch element 96a and the second latch element 98a of the wiring block 12a manually or by means of a screw driver or of another tool deemed expedient by a person having ordinary skill in the art, and is thus put into operation.
