DESCRIPTION OF THE EXEMPLARY EMBODIMENTS

[0060] FIG. 1 illustrates a plug connector device 10a in a schematic perspective view. The plug connector device 10a is configured to create a plug connection that extends along a plugging direction 14a.

[0061] The plug connector device 10a comprises a plug connector unit 12a. The plug connector unit 12a comprises a contact unit 16a. The contact unit 16a comprises at least two electric plug contacts 18a, 102a (see FIG. 6).

[0062] The plug connector unit 12a comprises a plug element 34a for an insertion into a plug socket (not shown).

[0063] The plug connector device 10a comprises a cable receiving unit 20a for receiving an electric cable 26a (see FIG. 2).

[0064] If there are a plurality of objects, only one of these objects is given a reference numeral in the figures.

[0065] FIG. 2 shows a schematic sectional view of the electric cable 26a. The electric cable 26a is embodied as a twisted-pair cable and is configured for a data transmission. The electric cable 26a comprises a plurality of conductor cores 24a. In the present case the electric cable 26a comprises eight conductor cores 24a in total. Each of the conductor cores 24a is encompassed by a core sheath 130a. Respectively two of the conductor cores 24a are twisted to form a core pair of the electric cable 26a. The electric cable 26a comprises a cable shield 42a. The cable shield 42a encompasses the conductor cores 24a along a circumferential direction 98a. The electric cable 26a comprises a cable jacket 38a. The cable jacket 38a encompasses the cable shield 42a along the circumferential direction 98a.

[0066] FIG. 3 shows the plug connector device 10a in a schematic exploded view. The plug connector unit 12a comprises a housing 36a. The housing 36a is made of a metallic die-cast material and is configured to accommodate the contact unit 16a and the plug element 34a.

[0067] The cable receiving unit 20a comprises a wiring block 22a for receiving conductor cores 24a of the electric cable 26a (see FIG. 2). The cable receiving unit 20a comprises a connection unit 28s for establishing a connection to at least one further element 30a of the cable 26a. The wiring block 22a is releasably connected to the connection unit 28a, namely via a plug connection. In the present case the further element 30a is the cable jacket 38a of the electric cable 26a (see FIG. 2).

[0068] The connection unit 28a comprises a connection base body 132a. The connection base body 132a has a thread 134a. The connection unit 28a comprises at least one connection element 94a. The connection element 94a comprises a plurality of lamellae 96a. The lamellae 96a are configured to engage around the further element 30a, in the present case the cable jacket 38a, of the electric cable 26a along the circumferential direction 98a (see FIG. 2). When the connection to the further element 30a of the electric cable 26a has been created by the connection unit 28a, the lamellae 96a of the connection element 94a are oriented counter to the plugging direction 14a. The lamellae 96a are configured for an optical indication. The connection unit 28a includes a further connection element 136a, which comprises a nut 138a corresponding to the thread 134a. In order to create the connection to the further element 30a of the electric cable 26a, the connection element 94a is slid onto the electric cable 26a together with the further connection element 136a in such a way that the lamellae 96a are oriented counter to the plugging direction 14a. Then the nut 138a is screwed onto the thread 134a, wherein the lamellae 96a are pressed toward the cable jacket 38a and the connection is created. As the lamellae 96a are oriented counter to the plugging direction 14a, an optical indication of the strength of the connection is given.

[0069] The connection unit 28a comprises a strain relief for the cable jacket 38a (see FIG. 2) of the electric cable 26a. The strain relief is brought about via the connection unit 28a by means of the connection element 94a and the further connection element 136a.

[0070] The connection unit 28a comprises a shield contact 40a for a contacting of the cable shield 42a (see FIG. 2) of the electric cable 26a. For a shield contacting, the shield contact 40a is connected to the cable shield 42a. By the connection brought about by the connection element 94a and the further connection element 136a, the shield contacting is additionally safeguarded from getting released counter to the plugging direction 14a.

[0071] The plug connector device 10a comprises a wiring assistance unit 32a. The wiring assistance unit 32a is configured for tool-lessly establishing a connection between the wiring block 22a and the contact unit 16a.

[0072] In FIGS. 4 and 5 a plug connector kit 100a for creating the plug connector device 10a is illustrated in two different perspective schematic views. The plug connector kit 100a comprises the plug connector unit 12a and the cable receiving unit 20a. The plug connector device 10a can be assembled from the plug connector kit 100a, wherein an especially simple and intuitive assembly is brought about due to the features of the wiring assistance unit 32a, which will be described below.

[0073] The wiring assistance unit 32a comprises a first sub-unit 44a. The first sub-unit 44a is part of the plug connector unit 12a. The wiring assistance unit 32a comprises a second sub-unit 46a which cooperates with the first sub-unit 44a. The second sub-unit 46a is part of the cable receiving unit 20a.

[0074] The first sub-unit 44a comprises a flap 48a. The flap 48a is pivotable around a pivot axis 50a that extends perpendicularly to the plugging direction 14a. The flap 48a is configured to provide a force that acts in the plugging direction 14a for establishing the connection between the wiring block 22a and the contact unit 16a. The flap 48a has at least one first inner contour 52a. The first inner contour 52a is configured to cooperate with a first outer contour 54a of the second sub-unit 46a. The flap 48a has a second inner contour 56a. The second inner contour 56a is configure to cooperate with a second outer contour 58a of the second sub-unit 46a. The first inner contour 52a and the second inner contour 58a are arranged offset from each other in the plugging direction 14a. Accordingly the first outer contour 54a and the second outer contour 58a are also arranged offset from each other in the plugging direction 14a.

[0075] The first inner contour 52a is configured for locking the connection between the wiring block 22a and the contact unit 16a. When the connection has been established, the inner contour 52a locks the wiring block 22a with the contact unit 16a counter to the plugging direction 14a.

[0076] The second sub-unit 46a comprises at least one first guiding cam 60a. The first outer contour 54a is formed by the guiding cam 60a. The second sub-unit 46a comprises at least one second guiding cam 64a. The second guiding cam 64a is arranged offset from the first guiding cam 60a in a circumferential direction 98a. The guiding cams 60a, 64a are configured to engage in corresponding guiding grooves 62a, 66a of the plug connector unit 12a. A first guiding groove 62a of the plug connector unit 12a corresponds to the first guiding cam 60a of the second sub-unit 46a. A second guiding groove 66a of the plug connector unit 12a corresponds to the second guiding cam 64a of the second sub-unit 46a. In the tool-less establishing of the connection between the wiring block 22a and the contact unit 16a, the guiding cams 60a, 64a engage in the respectively corresponding guiding grooves 62a, 66a of the plug connector unit 12a and are slid into the guiding grooves 62a, 66a in the plugging direction 14a by the force provided via the flap 48a.

[0077] A width extension 68a of the first guiding cam 60a, which extends perpendicularly to the plugging direction 14a, differs from a width extension 70a of the second guiding cam 64a, which extends perpendicularly to the plugging direction 14a. In the present case the width extension 70a of the second guiding cam 64a is greater than the width extension 68a of the first guiding cam 60a. The difference between the width extension 68a and the width extension 70a permits preventing an erroneous assembly when the connection between the wiring block 22a and the contact unit 16a is established.

[0078] FIG. 6 shows the contact unit 16a of the plug connector device 10a in two schematic illustrations. In a lefthand illustration the contact unit 16a is depicted in a schematic perspective manner. The contact unit 16a comprises at least four electric plug contacts 18a, 102a, 104a, 106a. The contact unit 16a comprises a circuit board 72a. In an assembled state of the contact unit 16a within the plug connector unit 12a, the circuit board 72a is oriented perpendicularly to the plugging direction 14a. The contact unit 16a comprises at least four connection lines 74a, 76a, 78a, 80a between the circuit board 72a and the electric plug contacts 18a, 102a, 104a, 106a, wherein in the assembled state each of the connection lines 74a, 76a, 78a, 80a connects respectively one of the electric plug contacts 18a, 102a, 104a, 106a to the circuit board 72a in an electrically conductive manner.

[0079] In the present case the contact unit comprises eight electric plug contacts in total, namely the four electric plug contacts 18a, 102a, 104a, 106a and four further electric plug contacts 108a, 110a, 112a, 114a. The further electric plug contacts 108a, 110a, 112a, 114a are in each case electrically conductively connected to the circuit board 72a via further connection lines 116a, 118a, 120a, 122a of the contact unit 16a.

[0080] The contact unit 16a comprises a plurality of insulation displacement contacts 124a, which are connected to the circuit board 72a. In the present case the contact unit 16a comprises eight insulation displacement contacts 124a in total. In the assembled state the insulation displacement contacts 124a are oriented counter to the plugging direction 14a. When the connection between the wiring block 22a and the contact unit 16a is established via the wiring assistance unit 32a, an electrically conductive connection is created between the conductor cores 24a of the electric cable 26a and the electric plug contacts 18a, 102a, 104a, 106a, respectively the further electric plug contacts 108a, 110a, 112a, 114a via the insulation displacement contacts 124a.

[0081] A righthand-side schematic illustration of FIG. 6 shows the circuit board 72a in a lateral view in a view direction along the plugging direction 14a. In a view along the plugging direction 14a, connection paths 126a, 128a between respectively two of the connection lines 74a, 76a, 78a, 80a are at least substantially perpendicular to each other. In the present case a first connection path 126a, which extends respectively diagonally through the connection points in which the connection line 74a and the connection line 76a are connected to the circuit board 72a, is at least substantially perpendicular to a second connection path 128a, which extends respectively diagonally through the connection points in which the connection line 78a and the connection line 80a are connected to the circuit board 72a. In an operating state of the plug connector device 10a, the electric plug contact 18a and the electric plug contact 102a, which are connected to the circuit board 72a via the connection line 74a and the connection line 76a, form a first conductor pair. In the operating state of the plug connector device 10a, the electric plug contact 104a and the electric plug contact 106a, which are connected to the circuit board 72a via the connection line 78a and the connection line 80a, form a second conductor pair. Due to the above-described arrangement of the connection lines 74a, 76a, 78a, 80a with connection paths 126a, 128a that are at least substantially perpendicular to each other, cross-talk between the first conductor pair and the second conductor pair can be reduced in the operating state of the plug connector device 10a.

[0082] FIG. 7 shows a schematic flow chart of a method for a field assembly of the electric cable 26a (see FIG. 2) with the plug connector device 10a. In the method at least one conductor core 24a of the electric cable 26a is connected to at least one electric plug contact 18a, 102a, 104a, 106a of the contact unit 16a. The method comprises at least two method steps. In a first method step 144a a cable preparation of the electric cable 26a is carried out; herein firstly the conductor cores 24a of the electric cable 26a are introduced into the wiring block 22a (see FIG. 3). After this the shield contacting is brought about between the shield contact 40a (see FIG. 3) and the cable shield 42a (see FIG. 2) in the first method step 144a. In the first method step 144a then the connection to the at least one further element 30a, which is different from a conductor core 24a, is created by means of the connection unit 28a (see FIG. 3), thus obtaining the strain relief of the cable 26a. In a second method step 146a of the method, the connection between the wiring block 22a and the contact unit 16a is established in a tool-less manner; this is done via the wiring assistance unit 32a (see FIGS. 4 and 5). Herein the conductor cores 24a are clamped into the insulation displacement contacts 124a of the contact unit 16a (see FIG. 6) in such a way that the core sheaths 130a encompassing the conductor cores 24a (see FIG. 2) are severed. In this way the conductor cores 24a are connected in an electrically conductive manner to the corresponding plug contacts 18a, 102a, 104a, 106a by the insulation displacement contacts 124a via the circuit board 72a and via the connection lines 74a, 76a, 78a, 80a.

The flap 48c is configured to provide a force acting in the plugging direction 14c for establishing the connection between the wiring block 22c and the contact unit 16c. The flap 48c has at least one first inner contour 52c. The first inner contour 52c is configured to cooperate with a first outer contour 54c of the second sub-unit 46c.

[0099] The first inner contour 52c is configured to lock the connection between the wiring block 22c and the contact unit 16c. When the connection has been established, the first inner contour 52c locks the wiring block 22c with the contact unit 16c counter to the plugging direction 14c.

[0100] The first sub-unit 44c comprises at least one first guiding cam 60c and at least one second guiding cam 64c. The second guiding cam 64c is arranged offset from the first guiding cam 60c in a circumferential direction. The guiding cams 60c, 64c are configured to engage in corresponding guiding grooves 62c, 66c of the second sub-unit 46c. A first guiding groove 62c of the second sub-unit 46c corresponds to the first guiding cam 60c of the first sub-unit 44c. A second guiding groove 66c of the second sub-unit 46c corresponds to the second guiding cam 64c of the first sub-unit 44c. In the present exemplary embodiment, the arrangement of the guiding cams 60c, 64c and the guiding grooves 62c, 66c are switched relative to the arrangement in the first exemplary embodiment. The guiding grooves 62c, 66c are in the present case arranged, on opposite-situated sides, in the wiring block 22c and the connection base body 132c, which are part of the second sub-unit 46c. The guiding cams 60c, 64c are arranged off-center with respect to a height extent 148c of the first sub-unit 44c. As a result, an anti-twist protection is enabled in assembly and a correct connection between the wiring block 22c and the contact unit 16c is ensured. In a tool-less establishment of the connection between the wiring block 22c and the contact unit 16c, the guiding cams 60c, 64c of the first sub-unit 44c engage in the respectively corresponding guiding grooves 62c, 66c of the second sub-unit 46c and are slid into the guiding grooves 62c, 66c via the force provided by the flap 48c counter to the plugging direction 14c.

[0101] FIG. 12 shows the contact unit 16c of the plug connector device 10c in three schematic illustrations. In a left-hand illustration the contact unit 16c is shown in a schematic perspective view. The contact unit 16c comprises at least four electric plug contacts 18c, 102c, 104c, 106c. The contact unit 16c comprises a circuit board 72c. In an assembled state of the contact unit 16c within the plug connector unit 12c, the circuit board 72c is oriented perpendicularly to the plugging direction 14c. The contact unit 16c comprises at least one further circuit board 150c, which is in the assembled state oriented parallel to the plugging direction 14c. The circuit board 72c and the further circuit board 150c are in each case embodied as printed circuit boards.

[0102] The contact unit 16c comprises, in addition to the four electric plug contacts 18c, 102c, 104c, 106c, four further electric plug contacts 108c, 110c, 112c, 114c. The electric plug contacts 18c, 102c, 104c, 106c and the further electric plug contacts 108c, 110c, 112c, 114c are in the assembled state plugged—in an alternating sequence—into the further circuit board 150c on an upper side. The contact unit 16c moreover comprises four further plug contacts 152c, 154c, 156c, 158c, which are in the assembled state plugged into the further circuit board 150c on its upper side opposite the electric plug contacts 18c, 102c, 104c, 106c. Respectively one of the electric plug contacts 18c, 102c, 104c, 106c is electrically conductively connected to respectively one of the further plug contacts 152c, 154c, 156c, 158c via a conductor path in the further circuit board 150c. The contact unit 16c furthermore comprises four further plug contacts 160c, 162c, 164c, 166c, which are in the assembled state plugged into the further circuit board 150c on its underside. Respectively one of the further electric plug contacts 108c, 110c, 112c, 114c is electrically conductively connected to respectively one of the further plug contacts 160c, 162c, 164c, 166c via a conductor path in the further circuit board 150c.

[0103] The contact unit 16c comprises at least one EON plug contact 168c, which is in the assembled state pressed into the circuit board 72c. In the present case, the further plug contacts 152c, 154c, 156c, 158c and the further plug contacts 160c, 162c, 164c, 166c are in each case realized as EON plug contacts 168c.

[0104] A middle schematic illustration of FIG. 12 shows the circuit board 72c in a lateral view in a view direction counter to the plugging direction 14c. The circuit board 72c comprises sixteen metallized pass-through openings 170c. The further plug contacts 152c, 154c, 156c, 158c, 160c, 162c, 164c, 166c, realized as EON plug contacts 168c, in each case have press-fit zones 184c. In a right-hand illustration of FIG. 12 the further plug contact 166c with a press-fit zone 184c is schematically shown by way of example. In the assembled state, the press-fit zones 184c are pressed into the circuit board 72c, thus connecting the further circuit board 150c to the circuit board 72c.

[0105] The contact unit 16c comprises a plurality of insulation displacement contacts 124c, which are connected to the circuit board 72c. The insulation displacement contacts 124c are also realized as EON plug contacts 168c and have a press-fit zone 184c for plugging into one of the metallized pass-through openings 170c. In the present case, the contact unit 16c comprises eight insulation displacement contacts 124c in total. In the right-hand illustration of FIG. 12 one of the insulation displacement contacts 124c is shown exemplarily. Regarding the functionality of the insulation displacement contacts 124c, the above description of FIG. 6 concerning the contact unit 16a of the first exemplary embodiment may be referred to.

[0106] FIG. 13 shows a further exemplary embodiment of a plug connector device 10d in a schematic view. The plug connector device 10d comprises a plug connector unit 12d for creating a plug connection that extends along a plugging direction 14d. The plug connector device 10d further comprises a cable receiving unit 20d.

[0107] The plug connector device 10d differs from the plug connector devices 10a-c of the preceding exemplary embodiments essentially in regard to an implementation of the cable receiving unit 20d.

[0108] The cable receiving unit 20d comprises a wiring block 22d (see FIG. 14) for an accommodation of conductor cores of an electric cable (not shown here, see FIG. 2). The wiring block 22d is implemented substantially identically to the wiring block 22c of the cable receiving unit 20c of the preceding exemplary embodiment.

[0109] The cable receiving unit 20d comprises a connection unit 28d for creating a connection to at least one further element (not shown here, see FIG. 2) of the electric cable.

[0110] FIG. 14 shows the cable receiving unit 20d in a schematic exploded view.

[0111] The cable receiving unit 20d comprises a guiding unit 82d for guiding the conductor cores of the electric cable from the connection unit 28d into the wiring block 22d. The guiding unit 82d connects the connection unit 82d to the wiring block 22d in an angled fashion.

[0112] Differently than in the second exemplary embodiment illustrated in FIGS. 8 and 9, the guiding unit 82d is realized in a multi-part implementation. The guiding unit 82d comprises a guiding base body 172d, which is oriented parallel to the plugging direction 14d, and two deflection elements 174d, 176d for an angled connection of the connection unit 28d to the wiring block 22d.

[0113] In an assembled state of the plug connector device 10d, the guiding base body 172d is connected to the wiring block 22d in the plugging direction 14d.

[0114] The deflection elements 174d, 176d are realized as corresponding half-shells and are configured for establishing a form-fit connection to the guiding base body 172d. The guiding base body 172d has on its rear side, opposed to the plugging direction 14d, a circumferential groove 178d. For the purpose of establishing the form-fit connection, latch edges 180d of the deflection elements 174d, 176d can be slid into the circumferential groove 178d.

[0115] The plug connector device 10d comprises a shield contact 40d, which is rotatably connected to the guiding base body 172d and is latchable in at least four positions. In the present case, the shield contact 40d is rotatable by 360°. The guiding base body 172d has four latch grooves (not shown), which are respectively arranged offset from each other by 90° and which the shield contact 40d can be latched into depending on a desired position. Like in the exemplary embodiment depicted in FIGS. 8 and 9, the shield contact 40d is pivotable around a further pivot axis 92d that extends perpendicularly to the plugging direction 14d.

[0116] For an assembly of the cable receiving unit 20d, the shield contact 40d is connected to the guiding base body 172d; it is rotated into the desired position and is latched in this position into one of the latch grooves of the guiding base body 172d. Then the shield contact 40d is pivoted around the further pivot axis 92d. After that, the conductor cores of the electric cable are connected to the wiring block 22d. Then the deflection elements 174d, 176d, which are realized as half-shells, are slid with their respective latch edges 180d into the circumferential groove 178d.

[0117] In the slid-in state, the deflection elements 174d, 176d together form a thread 134d. Analogously to the preceding exemplary embodiments, the connection unit 28d includes a further connection element 136d, which comprises a nut 138d that corresponds to the thread 134d. For a fixation of the deflection elements 174d, 176d in the slid-in state, the further connection element 136d is screwed onto the thread 134d. Analogously to the preceding exemplary embodiment, the connection unit 28d comprises a sleeve-like connection element 94d, which is configured to engage around a further element of the cable along a circumferential direction. Differently than in the preceding exemplary embodiment, the sleeve-like connection element 94d is configured to generate a resistance against a tensile load of the cable perpendicularly to the plugging direction 14d.

[0118] FIG. 13 exemplarily shows the plug connector device 10d with the cable receiving unit 20d in an assembled state in a first position, wherein the connection unit 28d is connected to the wiring block 22d (see FIG. 14) by means of the guiding unit 82d in an angled fashion, at an angle of 90°, and is oriented leftwards by means of the guiding unit 82d. Alternatively, the connection unit 28d is connectable to the wiring block 22d by means of the guiding unit 82d in an angled fashion in at least three further positions, these positions being in each case oriented perpendicularly to the plugging direction 14d. Relative to the first position shown in FIG. 13, the connection unit 28d would in a second position be rotated clockwise by 90° and would be oriented upwards, in a third position it would be rotated clockwise by 180° and would be oriented rightwards, and in a fourth position it would be rotated clockwise by 270° and would be oriented downwards (not shown).
