    DETAILED WRITTEN DESCRIPTION OF THE PREFERRED EMBODIMENTS

    [0107] This disclosure of the invention is submitted in furtherance of the Constitutional purposes of the US Patent Laws “to promote the progress of Science and the useful arts” (Article 1, Section 8).

    [0108] Before the individual variants and embodiments of an electrical plug connector according to the invention are explained in detail, the electrical plug connector assembly according to the invention in a preassembled state will be explained with reference to FIG. 1A, and the electrical plug connection formed of the assembled electrical plug connector and the associated electrical mating plug connector will be explained with reference to FIG. 1B:

    [0109] The electrical plug connector assembly 1, in the assembled state, comprises an electrical plug connector 2 and a cable 3 connected to the electrical plug connector 2 (see FIG. 1B). The electrical plug connector assembly 1, the electrical plug connector 2 and the cable 3 are each formed coaxially for transmission of a high-frequency signal.

    [0110] The cable 3 has an inner conductor 4, a dielectric 5 surrounding the inner conductor 4 concentrically, an outer conductor 6 surrounding the dielectric concentrically, and a cable sheath 7 surrounding the outer conductor 6 concentrically. The outer conductor 6 is formed as a corrugated metal tube. The region between the corrugated metal tube of the outer conductor 6 and the dielectric 5 is preferably filled with air, in order to allow a “corrugated cable” of this kind to bend slightly. The inner conductor 4 can also be formed as a corrugated metal tube or as a non-corrugated metal tube.

    [0111] The electrical plug connector 2 comprises an inner conductor contact element 8, an outer conductor contact element 9 and an insulator element 10, which is arranged between the inner conductor contact element 8 and the outer conductor contact element 9. The insulator element 10 spaces the inner conductor contact element 8 coaxially from the outer conductor contact element 9 and insulates them electrically from one another.

    [0112] The inner conductor contact element 8 has, on the cable side, a socket-like end 11 formed as a spring contact sleeve for receiving the inner conductor 4 of the cable 3 and for frictionally engaged connection thereto. On the plug side, the inner conductor contact element 8 preferably has a pin-like end 12 for contacting or for connection to the socket-like mating contact element of the electrical mating plug connector (see FIG. 1B). Alternatively, however, the plug-side end of the inner conductor contact element 8 can also be designed in the form of a socket.

    [0113] The outer conductor contact element 9 is designed in the form of a sleeve. An annularly shaped metal stop element 13 is arranged on a shoulder formed on the inner lateral surface of the outer conductor contact element 9 in the direction of the cable 3. The stop element 13 is preferably connected to the outer conductor contact element 9 by means of a press fit. However, other fastening techniques are also conceivable, for example a screw connection or a solder connection. The stop element 13 can alternatively also be connected in one part to the outer conductor contact element 9. A compression sleeve 14 is arranged axially adjacently to the stop element 13 in the direction of the cable 3.

    [0114] In the non-assembled state of the plug connector assembly 1, in which the cable 3 is not yet connected to the plug connector 2, the compression sleeve 14 is arranged so as to be movable axially within the plug connector 1. In the assembled state of the plug connector assembly 1, a press-fit connection is formed between the stop element 13 and the compression sleeve 14, for which the axial end 15 of the outer conductor 6 of the cable 3 exposed from the cable sheath 7 is clamped between an end face of the stop element 13 formed as a stop face 16 and the plug-side end region 17 of the compression sleeve 14. In order to deflect the axial end 15 of the outer conductor 6 of the cable 3 from its originally axial orientation during the compression into an axial and simultaneously a radial orientation, the stop element 13 has a tapering outer diameter in the direction of the cable 3. The tapering of the outer diameter of the stop element 13 is preferably foamed only in a region of the inner lateral surface of the sleeve-like stop element 13 in which the stop element 13 is extended in the direction of the cable 3 by an axial extension 18 by means of a conical outer lateral surface. The axial extension 18 with the conical outer lateral surface is preferably positioned radially on the stop element 13 in such a way that, during the assembly process, the tip of the conical extension 18 of the stop element 13 pierces precisely into the cable 3 between the dielectric 5 and the outer conductor 6 and deflects the axial end 15 of the outer conductor 6 axially and radially outwardly.

    [0115] The inner lateral surface 19 of the compression sleeve 14 is shaped in the form of a thread which corresponds to the outer lateral surface 20, also shaped in the form of a thread, of the outer conductor 6 of the cable 3 and consequently has the same thread pitch and the same tooth flank form and size. In the assembly process, the corrugated cable is screwed by means of the outer conductor 6 exposed from the cable sheath 7 into the compression sleeve 14. At the end of the screwing process, a longitudinal portion of the axial end 15 of the outer conductor 6 is screwed out from the foremost turn of the inner lateral surface 19, shaped in the form of a thread, of the compression sleeve 14, this being necessary for reliable clamping between the stop element 13 and the compression sleeve 14.

    [0116] The compression sleeve 14, in the case of the first variant of the first embodiment of the invention, is preferably produced from a plastic material in order to achieve a sufficient elasticity for the tilting of the axial end region relative to the rest of the region of the compression sleeve 14. In all other variants and embodiments of the invention, a metal material is also usable alternatively. The compression sleeve 14 is guided in the cable-side end region 21 sleeve-like outer conductor contact element 9. In the assembled state of the plug connector assembly 1 according to FIG. 1B, a fastening sleeve 22 acts axially in the direction of the stop element 13 on the compression sleeve 14 and pushes the plug-side end region 17 of the compression sleeve 14 against the stop face 16 of the stop element 13.

    [0117] The fastening sleeve 22 is fastened at the plug-side end 23 by means of a screw connection, or alternatively by means of a press-fit connection, to the outer lateral surface of the outer conductor contact element 9 and, at the cable-side end 24, has an end-face termination region 25 with a through-bore 26 for guiding through the cable 3. The assembly process between the fastening sleeve 22 and the compression sleeve 14 is performed by means of a stop face 27 of the fastening sleeve 22, which stop face 27 is formed on the inside of the end-face termination region 25 and pushes against a counter stop face 28 of the compression sleeve 14, which is formed on a flange-like, rib-like or shoulder-like region 2 or alternatively on the cable-side end face of the compression sleeve 14.

    [0118] In order to seal the plug connector assembly 1 on the cable side, a seal element 30 is preferably arranged between the cable sheath 7 of the cable 3 and the end-face termination region 25 of the fastening sleeve 22. In order to seal the plug connector assembly 1 on the plug side, a further seal element 30 is preferably inserted in a groove formed at the plug-side end 31 of the outer conductor contact element 9 on the outer lateral surface.

    [0119] The mechanical fastening between the electrical plug connector 2 and the associated electrical mating plug connector 32 of the electrical plug connection 33 is achieved in the known manner by means of a union nut 34, which is fastened movably on the plug connector 2. The internal thread formed on the inner lateral surface of the union nut 34 can be screwed to a corresponding external thread which is formed on the outer lateral surface of the outer conductor contact element 35 of the mating plug connector 32. The outer conductor contact element 35 of the mating plug connector 32 surrounds a dielectric 36 of the mating plug connector 32. The dielectric 36 of the mating plug connector 32 surrounds the inner conductor 37 of the mating plug connector 32. A spring contact sleeve 38, into which the inner conductor contact element 8 of the plug connector 2 is received, is formed at the plug-side end of the inner conductor contact element 37 of the mating plug connector 32. A further spring contact sleeve 39 is inserted at the plug-side end into the outer conductor contact element 35 of the mating plug connector 32, preferably by means of a press fit, and contacts the inner lateral surface of the outer conductor contact element 9 of the plug connector 2.

    [0120] In the cross-sectional illustrations of the following figures, the electrical plug connector 2 has been shown without the cable 3 for reasons of clarity.

    [0121] In a first variant of the first embodiment of a plug connector 2 according to the invention according to FIGS. 2A and 2B, the compression sleeve 14 has a slot-shaped recess 40, which is formed as a through-bore between the inner lateral surface and the outer lateral surface. This slot-shaped recess 40 preferably runs along a turn of the inner lateral surface 19, which is shaped in the form of a thread. As can be seen from the cross-sectional illustrations of FIGS. 2A and 2B, the slot-shaped recess 40 extends only over an angular segment that is reduced relative to the full angular circumference equal to 360°.

    [0122] In addition, the normal vector L.sub.SEP of the axial end face 42 of the axial end region 41 of the compression sleeve 14, in the non-assembled state of FIG. 2A, is rotated relative to the longitudinal axis L.sub.P of the compression sleeve 14 or the longitudinal axis L.sub.S of the plug connector 2 by an orientation angle φ.sub.A. The orientation angle φ.sub.A preferably corresponds to the pitch angle of the thread path of the inner lateral surface, shaped in the form of a thread, of the compression sleeve 14. The axial end face 42 of the axial end region 41 of the compression sleeve 14 is therefore formed as an inclined plane relative to an axial end face oriented in the longitudinal direction L.sub.S of the plug connector 2.

    [0123] In the assembled state of the plug connector 2, in which the axial end 15 of the outer conductor 8 of the cable 3 is clamped between the stop element 13 and the compression sleeve 14, the slot-shaped recess 40 according to FIG. 2B is preferably closed. An axial end region 41 of the compression sleeve 14, which on the plug side is arranged adjacently closest to the stop element 13, is thus tilted relative to the rest of the region of the compression sleeve 14.

    [0124] In the non-assembled state of the plug connector 2, the longitudinal axis L.sub.P of the compression sleeve 14, the longitudinal axis L.sub.A of the stop element 13 and the longitudinal axis L.sub.S of the plug connector 2 according to FIG. 2A lie on the same line. In the assembled state of the plug connector 2, the longitudinal axis L.sub.AEP of the tilted axial end region 41 of the compression sleeve 14 is tilted by a tilt angle φ.sub.K relative to the longitudinal axis L.sub.A of the stop element 13 corresponding to the longitudinal axis L.sub.S of the plug connector 2, in accordance with FIG. 2B. In the assembled state, the normal vector L.sub.SEP of the axial end face 42 of the axial end region 41 of the compression sleeve 14 is still rotated relative to the longitudinal axis L.sub.AEP of the tilted axial end region 41 of the compression sleeve 14 by the orientation angle φ.sub.A.

    [0125] As a result of the tilting of the axial end region 41 of the compression sleeve 14 and as a result of the incline φ.sub.A of the axial end face 42 relative to the longitudinal axis L.sub.AEP of the tilted axial end region 41 of the compression sleeve 14 in combination with the conical outer lateral surface of the axial extension 18 of the stop element 13, the plug-side end region 17 of the compression sleeve 14 is pushed over the entire angular circumference of 360° against the stop face 16 of the conically shaped axial extension 18 of the stop element 13. The axial end 15 of the outer conductor 6 of the cable 3 is thus also clamped optimally over the entire angular circumference of 360° between the compression sleeve 14 and the stop element 13, thus resulting in a constant contact pressure and therefore a constant transition resistance between the corrugated outer conductor 8 of the cable 3 and the outer conductor contact element 9 of the plug connector 2 over the entire angular circumference of 360°.

    [0126] Instead of a slot-shaped recess 40 formed as a through-bore according to FIGS. 2A and 2B, a compression sleeve 14 with a slot-shaped recess 40 formed as a blind bore can also be used alternatively. The blind bore, in accordance with FIG. 2C, is preferably formed on the outer lateral surface of the compression sleeve 14 in such a way that the rest of the wall of the compression sleeve 14 between the blind bore and the inner lateral surface 19, shaped in the form of a thread, of the compression sleeve 14 is deformable by the pressing force in the assembly process for tilting of the axial end region 41 by the tilt angle φ.sub.K.

    [0127] FIGS. 3A to 3D show the assembly process between the stop element 13 and the compression sleeve 14 slotted by a slot-shaped recess 40, during which process the normal vector L.sub.SEP of the axial end face 42 of the axial end region 41 of the compression sleeve 14 is directed along the longitudinal axis L.sub.A, L.sub.S, L.sub.P of the stop element 13, of the plug connector 2 and of the compression sleeve 14 respectively. By means of such a non-inclined design of an axial end face 42 of the axial end region 41 of the compression sleeve 14, a ridge-like region 43 is formed at the axial end face 42 at least over a certain angular segment, as can be seen in particular from FIG. 3A.

    [0128] At a first point of the assembly process, which is shown in FIG. 3A, there is a first contact between the stop face 16 of the stop element 13 and the plug-side axial end region 17 of the compression sleeve 14, only in a small angular segment of the compression sleeve 14. This contacting angular segment is preferably opposite the angular segment in which the ridge-like region 43 is formed on the compression sleeve 14 (in the right-hand region of FIG. 3A). The slot-shaped recess 40 in the compression sleeve 14 is still fully open at this point of the process.

    [0129] At a second point of the assembly process, which is shown in FIG. 3B, there is a first contact between the ridge-like region 43 of the compression sleeve 14 and the stop face 16 of the stop element 13. The slot-shaped recess 40 and the compression sleeve 14 is at this point of the process already pressed slightly in the axial direction and thus reduced.

    [0130] At a third point of the assembly process, which is shown in FIG. 3C, the ridge-like region 43 of the compression sleeve 14 is compressed against the opposite stop face 16 of the stop element 13. The slot-shaped recess 40 and the compression sleeve 14 is at this point of the process already closed to an advanced extent.

    [0131] At a fourth point of the assembly process, which is shown in FIG. 3D, the compression of the ridge-like region 43 of the compression sleeve 14 at the opposite stop face 16 of the stop element 13 is complete. The ridge-like region 43 of the compression sleeve 14 is fully compressed or “levelled”. The slot-shaped recess 40 in the compression sleeve 14 is fully closed at this point of the process. Here, the axial end 15 (not shown in FIG. 3D) of the outer conductor 8 of the cable 3 is clamped between the plug-side axial end region 17 of the compression sleeve 14 and the stop face 16 of the stop element 13 without the presence of an air gap over the entire circumference of 360°.

    [0132] In a second variant of the first embodiment of a plug connector 2 according to the invention according to FIGS. 4A and 4B, the compression sleeve 14 is formed without a slot-shaped recess 40. During the assembly process, the entire compression sleeve 14 is tilted. In the assembled state according to FIG. 4B, the longitudinal axis L.sub.P of the compression sleeve 14 is tilted by the tilt angle φ.sub.K relative to the longitudinal axis L.sub.A of the stop element 13 or the longitudinal axis L.sub.S of the plug connector 2. In order to bring about a tilting of the compression sleeve 14 during the assembly process, the cable-side end face of the compression sleeve 14, which forms the mating stop face 28 of the compression sleeve 14, has an incline φ.sub.A relative to the longitudinal axis L.sub.P of the compression sleeve 14 equal to the tilt angle φ.sub.K, i.e. the normal vector L.sub.KEP of the mating stop face 28 of the compression sleeve 14 is rotated by the orientation angle φ.sub.A relative to the longitudinal axis L.sub.P of the compression sleeve 14. The fastening sleeve 22 which in the assembly process pushes by means of the stop face 27 against the mating stop face 28 of the compression sleeve 14, brings about a tilting of the compression sleeve 14 by the tilt angle φ.sub.K in the assembly process. In the assembled state, the mating stop face 28 of the compression sleeve 14 has an orientation parallel to the longitudinal axis L.sub.A of the stop element 13 for the longitudinal axis L.sub.S of the plug connector 2.

    [0133] In addition, the plug-side end face 42 of the compression sleeve 14 has an incline φ.sub.A relative to the longitudinal axis L.sub.P of the compression sleeve 14 equal to the tilt angle φ.sub.K, i.e. the normal vector L.sub.SEP. The plug-side end face 42 of the compression sleeve 14 is rotated by the orientation angle φ.sub.A relative to the longitudinal axis L.sub.P of the compression sleeve 14.

    [0134] As a result of the tilting of the compression sleeve 14 and as a result of the incline φ.sub.A of the plug-side end face 42 of the compression sleeve 14, the plug-side end region 17 of the compression sleeve 14 is pushed over the entire angular circumference of 360° against the stop face 16 of the conically shaped axial extension 18 of the stop element 13. The axial end 15 of the outer conductor 6 of the cable 3 is thus optimally clamped between the compression sleeve 14 and the stop element 13 over the entire angular circumference of 360° without the presence of an air gap. In order to allow a tilting of the compression sleeve 14 within the outer conductor contact element 9, the cable-side end region 21 of the sleeve-like outer conductor contact element 9 must preferably be formed shorter and with a larger inner diameter than in the first variant.

    [0135] In a first variant of the second embodiment of a plug connector 2 according to the invention according to FIGS. 5A and 5B, a slot-shaped recess 44, preferably a slot-shaped recess 44 shaped as a through-bore, is formed in the stop element 13, equivalent later the first variant of the first embodiment of the invention. The forming of the slot-shaped recess 44 in the stop element 13 produces in the stop element 13, on the cable side, an axial end region 45 of the stop element 13 which has a certain elastic movability compared to the rest of the region of the stop element 13. In respect of the forming of the slot-shaped recess 44 in the stop element 13, the technical features already explained in relation to the slot-shaped recess 40 of the compression sleeve 14 are equivalent.

    [0136] In addition, the cable-side end face 42 of the compression sleeve 14, as already explained in the two variants of the first embodiment of the invention, has an incline φ.sub.A relative to the longitudinal axis L.sub.P of the compression sleeve 14 equal to the tilt angle φ.sub.K, i.e. the normal vector L.sub.SEP of the end face 42 of the compression sleeve 14 is rotated by the orientation angle φ.sub.A relative to the longitudinal axis L.sub.P of the compression sleeve 14.

    [0137] As a result of the assembly process, the slot-shaped recess 44 in the stop element 13 is at least partly closed. The cable-side axial end region 45 of the stop element 13 is tilted by the tilt angle φ.sub.K. In the assembled state of the plug connector 2, the longitudinal axis L.sub.AEA of the axial end region 45 of the stop element 13 is tilted relative to the longitudinal axis L.sub.S of the plug connector 2 or the longitudinal axis L.sub.P of the compression sleeve 14 by the tilt angle φ.sub.K.

    [0138] As a result of the tilting of the axial end region 45 of the stop element 13 and as a result of the incline φ.sub.A of the plug-side end face 42 of the compression sleeve 14, the plug-side axial end region 17 of the compression sleeve 14 is pushed over the entire angular circumference of 360° against the stop face 16 of the conically shaped axial extension 18 of the stop element 13. The axial end 15 of the outer conductor 6 of the cable 3 is thus clamped optimally between the compression sleeve 14 and the stop element 13 over the entire angular circumference of 360°, without the presence of an air gap.

    [0139] In a second variant of the second embodiment of the invention according to FIGS. 6A and 6B, the stop element 13 is tilted during the assembly process by the tilt angle φ.sub.K. In order to allow a tilting of the stop element 13 within the outer conductor contact element 9, the inner diameter of the outer conductor contact element 9 must be slightly increased and the end-face support face of the stop element 13 on the outer conductor contact element 9 must be designed with an incline.

    [0140] The plug-side end face 42 of the compression sleeve 14 likewise has an incline φ.sub.A relative to the longitudinal axis L.sub.P of the compression sleeve 14 equal to the tilt angle φ.sub.K, i.e. the normal vector L.sub.SEP of the end face 42 of the compression sleeve 14 is rotated by the orientation angle φ.sub.A relative to the longitudinal axis L.sub.P of the compression sleeve 14 The stop element 13 is tilted in that the plug-side axial end region 17 of the compression sleeve 14 pushes against the stop face 16 of the stop element 13.

    [0141] As a result of the tilting of the stop element 13 and as a result of the incline φ.sub.A of the plug-side end face 42 of the compression sleeve 14, the plug-side axial end region 17 of the compression sleeve 14 is pushed over the entire angular circumference of 360° against the stop face 16 of the conically shaped axial extension 18 of the stop element 13. The axial end 15 of the outer conductor 6 of the cable 3 is thus clamped optimally between the compression sleeve 14 and the stop element 13 over the entire angular circumference of 360°, without the presence of an air gap.

    [0142] In a third embodiment of the invention according to FIGS. 7A and 7B, the plane 46 which is spanned by an edge 47 between the end face, i.e. the stop face 16 and the inner lateral surface 48 of the stop element 13, has an incline φ.sub.A equal to the tilt angle φ.sub.K, i.e. the normal vector L.sub.KEA of this plane 46 is rotated by the orientation angle φ.sub.A relative to the longitudinal axis L.sub.S of the plug connector 2 or the longitudinal axis L.sub.P of the compression sleeve 14 or the longitudinal axis L.sub.A of the stop element 13.

    [0143] The plug-side end face 42 of the compression sleeve 14 likewise has an incline φ.sub.A equal to the tilt angle φ.sub.K, i.e. the normal vector L.sub.SEP of the cable side end face 42 of the compression sleeve 14 is rotated by the orientation angle φ.sub.A relative to the longitudinal axis L.sub.S of the plug connector 2 or the longitudinal axis L.sub.P of the compression sleeve 14 or the longitudinal axis L.sub.A of the stop element 13.

    [0144] Due to the identical incline φ.sub.A of the plug-side end face 42 of the compression sleeve 14 and the plane 46, the plug-side end region 17 of the compression sleeve 14 is pushed against the stop face 16 of the conically shaped axial extension 18 of the stop element 1 over the entire angular circumference of 360°. The axial end 15 of the outer conductor 6 of the cable 3 is thus damped optimally between the compression sleeve 14 and the stop element 13 over the entire angular circumference of 360°, without the presence of an air gap.

    [0145] Instead of the inclined plug-side end face 42 of the compression sleeve 14, a plug-side end face 42 of the compression sleeve 14 of which the normal vector L.sub.SEP is directed along the longitudinal axis L.sub.S of the plug connector 2 and on which there is formed a ridge-like region 43 in a certain angular range can also be used alternatively in the individual variants and embodiments of the invention.

    [0146] In a fourth embodiment of the invention according to FIGS. 8A to 8C, the edge 47 between the end face, i.e. the stop face 16, and the inner lateral surface 48 of the stop element 13, in the direction of the longitudinal axis L.sub.S of the plug connector 2 has a helical course, which corresponds to the helical course of the thread turn or the inner lateral surface 19 of the compression sleeve 14. In the assembled state of the plug connector assembly 1 according to FIG. 8B, the conically shaped region of the stop face 16 of the stop element 13 thus runs parallel to the tooth flank face of the foremost turn of the internal thread formed in the compression sleeve 14. The stop face 16 of the stop element 13 preferably has a conical flank.

    [0147] The axial end 15 of the outer conductor 6 of the cable 3 is thus clamped with constant contact pressure over the entire angular circumference of 360° between the axial end region 17 of the compression sleeve 14 and the stop face 16 of the stop element 13.

    [0148] Although the present invention has been described above in full with reference to preferred exemplary embodiments, it is not limited to these and can be modified in a variety of ways.
