Description

TECHNICAL FIELD

[0001] The present application relates to a plug connector device having a plug connector and a cable connected to the plug connector. The plug connector device is particularly suitable for cables having at least one twisted pair of inner conductors. BACKGROUND

[0002] In practice, plug connector systems are used to detachably connect cables to electrical components or further cables. Plug connector systems create an electrically conductive and mechanically stable connection between the cable and the desired connection partner. To this end, contact elements are usually mounted at the cable, which contact elements can be coupled with complementary contact elements at the connection partner. In the course of increasing digitalization and automation, ever higher demands are placed on the transmission rate of, in particular, high-frequency data cables. However, a particular problem arises here with the desire for detachable connections. This is particularly because the plug connector systems required here have deficiencies in terms of electrical properties. For example, the attenuation of high-frequency signals to be transmitted is often adversely affected by the plug connection.

[0003] This problem is particularly pronounced with cables having a twisted pair of inner conductors, so-called twisted pair cables. In order to be able to attach contact elements at the inner conductors of the cable, which contact elements enable a connection to the connection partner, it is often unavoidable to sectionally untwist the inner conductors. In addition, such cables can have an additional shield for improving signal transmission, which shield surrounds the twisted inner conductors. Usually, this shield must also be sectionally removed in order to be able to attach the connection elements to the inner conductors. However, these measures have a particularly adverse effect on the signal transmission properties of the cable or the connection. In order to ensure compatibility of different connector systems, there are additional requirements for standardized connector systems, in particular in the automotive sector, for example by defined insertion geometries. However, because the design freedom of the respective connection system is thereby restricted, this requirement makes it difficult to provide a connection system which additionally has as little negative influence as possible on the electrical properties of the cable.

[0004] DE 10 2018 104 253 A1 discloses a plug connector device with a plug connector and a cable having a first conductor and a second conductor for transmitting a differential signal. The cable has a first section and the plug connector has a second section, in which the conductor pair has plug contacts. The cable is fixed at the plug connector at the end of the plug connector side of the first section. The conductors of the conductor pair are fixed at the conductors of the plug connector at the end of the cable side of the second section. An intermediate section is formed between the first section and the second section, in which the conductor pair is surrounded by an outer conductor in the intermediate section. The outer conductor has a deformation in at least one portion of the intermediate section, which reduces the spacing between the outer conductor and the conductors or reduces the spacing between the conductors in the region of the deformation.

[0005] DE 10 2018 132 823 A1 discloses a cable plug connector device having a cable plug connector and an electrical cable with a plurality of individual wires each having an insulating material and an electrical conductor, which individual wires comprise a front section for connecting to a corresponding mating plug connector, a rear section in which the individual wires are surrounded by a cable jacket, and an intermediate section located therebetween. The electrical conductors of two individual wires have a first mutual nominal spacing in the rear section and a second mutual spacing greater than the first spacing in the front section, wherein the spacing of the electrical conductors of the two individual wires increases in the intermediate section in the direction of the front section. At least one pressing mechanism is formed in the intermediate section in order to press at least two individual wires against each other so that their insulating material is mechanically deformed.

[0006] In this regard, it is a common feature of the solutions disclosed in the prior art that the electrical properties are only slightly improved by the respective plug connector and / or the attachment of the plug connector to the associated cable is associated with very high installation costs. SUMMARY

[0007] It is therefore an object of the present application to overcome at least one of the disadvantages mentioned in the prior art and to provide a plug connector device which influences the electrical properties of a cable connected to the plug connector device as little as possible and which is also easy to manufacture and can be installed at the cable.

[0008] The object according to the present application is achieved by a plug connector device having the features of the independent claims. Further advantageous design forms of the present application can be gathered from the dependent claims, the description and the drawings.

[0009] The plug connector device according to the application comprises a plug connector and a cable connected to the plug connector. The cable has a first insulated inner conductor and a second insulated inner conductor. Both the first inner conductor and the second inner conductor can comprise one or more electrically conductive core wires surrounded by an insulating material. The inner conductors are preferably twisted with one another and preferably form an inner conductor pair for transmitting a differential signal. The first inner conductor and the second inner conductor are surrounded by a shield. Here, the shield surrounds both inner conductors jointly. The shield can be, for example, a metal braid. Additionally, a shielding film can be arranged between the shield and the first inner conductor and the second inner conductor or between the shield and the outer jacket, which also surrounds both inner conductors jointly. The shield is in turn surrounded by an outer jacket. The first inner conductor and the second inner conductor are exposed from the shield and the outer jacket in an end section of the cable. To this end, the shield can be partially removed, partially widened and / or folded over, for example. The outer jacket is preferably removed over the entire end section. The plug connector has an outer conductor sleeve, a first inner conductor contact and a second inner conductor contact. The first inner conductor contact and the second inner conductor contact are arranged inside the outer conductor sleeve. The first inner conductor contact and the second inner conductor contact each have a plug-in section, in which the first inner conductor contact and the second inner conductor contact can be connected to complementary inner conductor contacts of a mating plug connector. Furthermore, the first inner conductor contact and the second inner conductor contact have a connection section, in which the first inner conductor contact is electrically conductively connected to the first inner conductor and the second inner conductor contact is electrically conductively connected to the second inner conductor. In order to be able to establish an electrically conductive connection between the inner conductor and the respective inner conductor contact, the insulating material of the inner conductor can be removed in the region of the connection region of the inner conductor contact. The inner conductor can be connected to the inner conductor contact by means of crimping, for example. The plug-in section and the connection section of the first inner conductor contact and the second inner conductor contact are each connected to one another by means of a transition section.

[0010] Furthermore, the first inner conductor contact and the second inner conductor contact are arranged parallel to each other in the plug-in section and in the connection section. Furthermore, the plug-in section is arranged at least parallel to a plug-in direction of the plug-in connector. It is preferred in this regard that the respective connection section is arranged parallel to the respective plug-in section. The first inner conductor contact and the second inner conductor contact have a first contact spacing in the plug-in section and a second contact spacing in the connection section. In this regard, the first contact spacing is greater than the second contact spacing. The transition from the first contact spacing to the second contact spacing is realized in the transition section. Here, the transition is continuous over the length of the transition section. Continuous can be understood as a smooth, in particular linear, transition without jumps and / or steps. With the continuous transition between the first contact spacing and the second contact spacing, it can be ensured that structural interferences which have a negative effect on the electrical properties are as few as possible. The first inner conductor and the second inner conductor are arranged parallel to each other inside the outer conductor sleeve in the end section. If it is a cable with inner conductors which are twisted with each other, this twisting of the inner conductors is preferably at least released in the end section. Preferably, a sub-section of the end section in which the first inner conductor and the second inner conductor are arranged parallel to each other is longer than a sub-section of the end section in which the first inner conductor and the second inner conductor are not arranged parallel to each other. Even more preferably, a sub-section of the end section in which the first inner conductor and the second inner conductor are arranged parallel to each other is longer than any further sub-section of the end section in which the first inner conductor and the second inner conductor are not arranged parallel to each other. Furthermore, the first inner conductor and the second inner conductor can be arranged parallel to each other in the entire end section. Furthermore, the first inner conductor and the second inner conductor are arranged in the end section at a distance from the outer conductor sleeve, so that the first inner conductor contact and the second inner conductor contact are arranged contact-free from the outer conductor sleeve inside the outer conductor sleeve. The first inner conductor and the second inner conductor are arranged parallel to each other in the end section with a wire spacing which is equal to the second contact spacing. The wire spacing is preferably constant in the end section, wherein the wire spacing is preferably equal to the sum of the thickness of the insulation of the first inner conductor and the thickness of the insulation of the second inner conductor.

[0011] The contact spacing can be understood as the shortest path between the imaginary center point of the cross-section of the first inner conductor contact which extends perpendicular to the main extension direction to the imaginary center point of the cross-section of the second inner conductor contact which extends perpendicular to the main extension direction.

[0012] The wire spacing can be understood as the shortest path between the imaginary center point of the cross-section of the first inner conductor which extends perpendicular to the main extension direction to the imaginary center point of the cross-section of the second inner conductor which extends perpendicular to the main extension direction.

[0013] By means of the plug connector device according to the application a connection possibility can be produced which has a significantly less influence on the electrical properties of the cable. Furthermore, the construction of the plug connector device is characterized by low complexity, so that the manufacture and the connection to the cable of the plug connector device is significantly simpler and less costly compared to the solutions known from the prior art.

[0014] The plug-in sections of the first and second inner conductor contact portions can be arranged in a main plane. Furthermore, the connection sections and / or the transition sections can also be arranged in the main plane. It is also particularly advantageous if the first and second inner conductors are arranged in the main plane. Furthermore, it is preferred if the plug-in sections, the transition sections, the connection sections and / or the imaginary center points of the cross sections of the first and second inner conductors which extend perpendicular to the main extension direction are arranged on the main plane.

[0015] The first and second inner conductor contact portions can be arranged symmetrically, in particular mirror-symmetrically, to one another, wherein a symmetry plane can be arranged perpendicular to the main plane and parallel to the plug-in direction. Furthermore, it is preferred if the first and second inner conductors are also arranged symmetrically with respect to the symmetry plane. The symmetry plane preferably extends between the first and second inner conductor contact portions or the inner conductors.

[0016] The first and / or second inner conductor contact portions can enclose an angle with the symmetry plane in the transition section, the tangent function of which is equal to the result of a quotient, the dividend of which is formed by the difference between the first contact portion spacing and the second contact portion spacing and the divisor of which is formed by the double length of the transition section. For the difference, the first contact portion spacing forms the minuend and the second contact portion spacing forms the subtrahend. Here, the length of the transition section preferably relates to the extension of the transition section in one dimension parallel to the plug-in direction.

[0017] It is preferred if one leg of the angle is formed by the symmetry plane itself and the other leg is formed by the inner conductor contact portion in the transition section. If the transition section does not have a linear shape, the legs are preferably formed by the main extension direction of the transition section.

[0018] The first and second inner conductors can be arranged inside the shielding film in the end section. It is preferred for this that the first and second inner conductors are jointly arranged in the shielding film. It is also preferred that the shielding film in the end section is only removed in the region of the inner conductors, in which the insulating material of the inner conductors is removed.

[0019] The plug connector can have an insulation body with a first plug cavity and a second plug cavity. The insulation body can be arranged inside the outer conductor sleeve. A first inner conductor contact can be arranged in the first plug cavity and a second inner conductor contact can be arranged in the second plug cavity. The inner conductor contacts are preferably connected to the insulation body in a form-fit manner. The plug cavities are preferably arranged parallel to one another and parallel to the plug-in direction. The first inner conductor contact and the second inner conductor contact preferably have a constant distance from the outer conductor sleeve inside the insulation body in the plug-in direction.

[0020] The first plug cavity and the second plug cavity can each have a first plug cavity section in which the plug-in section of the respective inner conductor contact is arranged, and a second plug cavity section in which the connection section and the transition section of the respective inner conductor contact are arranged. In this context, the first plug section can have a smaller diameter than the second plug section. The first plug cavity and / or the second plug cavity can also have recesses for form-fit connection with the respective inner conductor contact arranged in the plug cavity. For example, the inner conductor contact can have a locking lug which engages in the recess. The recess is preferably arranged in the first plug cavity section.

[0021] In the region of the insulation body, the outer conductor sleeve can have a collar element with at least one fastening element on the side facing away from the insulation body. The collar element can be arranged at the outer conductor sleeve, for example, as a pressure injection-moulded encapsulation of the outer conductor sleeve. The fastening element is preferably formed in one piece and made of the same material as the collar element. The fastening element is preferably used to connect the plug connector with a plug connector housing. For example, the fastening element can be designed as a snap connector which can be detachably connected with the plug connector housing.

[0022] The plug connector can be connected with a cable via a press sleeve. By the press sleeve being connected with the cable and the plug connector in a force-fit manner by means of a reduced diameter, the cable and the plug connector are preferably arranged inside the press sleeve and are preferably connected with the press sleeve. The press sleeve can have regions of different diameter. It is preferred here that the press sleeve has a greater diameter in the region in which the plug connector is arranged inside the press sleeve than in the region in which the cable is arranged. It is furthermore preferred that the press sleeve is non-detachably connected with the outer conductor sleeve and with the outer housing.

[0023] A shield can be arranged between the press sleeve and the outer conductor sleeve. The outer conductor sleeve can have a profile on the side facing towards the press sleeve, into which profile the shield is at least partially pressed. It is also preferred that the shield is widened in an end section, so that the shield can in particular be arranged without problems between the press sleeve and the outer conductor sleeve. It is also preferred that the outer conductor sleeve is in electrically conductive connection with the shield.

[0024] The outer conductor sleeve can have a compression region, in which the outer conductor sleeve is connected with the compression sleeve and the shield. The outer conductor sleeve can have a middle region connected to the compression region. The first inner conductor and the second inner conductor can have a greater spacing to the outer conductor sleeve in the compression region than in the middle region. It is particularly preferred here that the spacing of the inner conductors to the outer conductor sleeve remains constant in the middle region and / or the compression region. It is further preferred that the outer conductor sleeve has a constant inner diameter in the compression region and / or the middle region, but the outer conductor sleeve has a greater inner diameter in the compression region than in the middle region. In this context, the spacing of the inner conductors to the outer conductor sleeve is to be understood as the shortest path from the inner conductor to the outer conductor sleeve.

[0025] The inner conductor contact can have a spacing to the outer conductor sleeve in the connection section, which is greater than the spacing of the inner conductor to the outer conductor sleeve in the middle region. This is preferably ensured by the outer conductor sleeve having a greater inner diameter in the region of the exposed inner conductor than in the middle region. The middle region is preferably connected at the compression region in the plug-in direction. Here, the spacing which the inner conductor contact to the outer conductor sleeve has in the connection section is preferably constant along the main extension of the connection section.

[0026] In the connection section, the inner conductor contact to the outer conductor sleeve can have a spacing which is equal to the spacing of the inner conductor to the outer conductor sleeve in the compression region.

[0032] Figure 1 An embodiment of the plug connector device 1 according to the application is shown in a sectional view. The section plane runs parallel to the plug-in direction x and in the main plane. The plug connector device 1 consists of a plug connector 2 and a cable 3. The cable 3 consists of a first and a second insulated inner conductor 4.1, 4.2, which are each surrounded by an insulating material 6. The two inner conductors 4.1, 4.2 are surrounded by a common shield 7. In the present embodiment, the shield 7 is formed by a tubular metal braid, which surrounds the two inner conductors 4.1, 4.2. A shielding film 8 is additionally arranged between the shield 7 and the inner conductors 4.1, 4.2. The shield 7 is surrounded by an outer jacket 9, which protects the inner conductors 4.1, 4.2 from external influences.

[0033] The plug connector 2 consists of an outer conductor sleeve 11, in which the insulator 5 is arranged. The insulator 5 has a first and a second plug-in cavity 19.1, 19.2. The two plug-in cavities 19.1, 19.2 are each divided into a first plug-in cavity section 20.1, 20.2 and a second plug-in cavity section 21.1, 21.2. The second plug-in cavity sections 21.1, 21.2 each have a greater diameter than the first plug-in cavity sections 20.1, 20.2. The two plug-in cavities 19.1, 19.2 each have their center axis running parallel to the plug-in direction x and in the main plane. Furthermore, the two plug-in cavities 19.1, 19.2 run parallel to one another.

[0034] The first inner conductor contact 12.1 is arranged inside the first plug-in cavity 19.1. The second inner conductor contact 12.2 is arranged inside the second plug-in cavity 19.2. The first and the second inner conductor contact 12.1, 12.2 each have a plug-in section 13.1, 13.2, a connection section 14.1, 14.2 and a transition section 15.1, 15.2. Here, the plug-in sections 13.1, 13.2 are arranged in the first plug-in cavity sections 20.1, 20.2. The inner conductor contacts 12.1, 12.2 each have a locking lug 18 in the plug-in section 13.1, 13.2. The locking lug 18 is arranged in a recess 27 of the insulator 5, so that the inner conductor contacts 12.1, 12.2 are form-fittingly, but detachably fastened in the insulator 5. The connection sections 14.1, 14.2 and the transition sections 15.1, 15.2 are arranged in the second plug-in cavity sections 21.1, 21.2. The first inner conductor contact 12.1 and the second inner conductor contact 12.2 have a first contact section spacing a in the plug-in sections 13.1, 13.2 and a second contact section spacing b in the connection sections, wherein the first contact section spacing a is greater than the second contact section spacing b. Here, the transition between the first contact section spacing a and the second contact section spacing b is realized in the transition sections 15.1, 15.2.

[0035] The two inner conductors 4.1, 4.2 are exposed from the shield 7 and the outer jacket 9 in the end section and extend parallel to one another. The exposed inner conductors 4.1, 4.2 are arranged inside the outer conductor sleeve 11. The first inner conductor 4.1 is in electrically conductive connection with the first inner conductor contact 12.1 in the connection section 14.1. The second inner conductor contact 12.2 is in electrically conductive connection with the second inner conductor contact in the connection section 14.2. In order to achieve an electrically conductive connection between the inner conductors 4.1, 4.2, the insulation material 6 is partially removed in the case of both inner conductors 4.1, 4.2, wherein the exposed inner conductors 4.1, 4.2 are crimped with the connection sections 14.1, 14.2. The inner conductors 4.1, 4.2 are arranged at a wire spacing c. In this regard, the wire spacing c is equal to the second contact spacing b. The cable 3 is arranged mirror-symmetrically to the plug connector 2 in the region of the end section. In this regard, a symmetry plane 17 extends parallel to the plug-in direction x and perpendicular to the main plane in the middle between the inner conductors 4.1, 4.2 and the inner conductor contacts 12.1, 12.2.

[0036] The plug connector 2 is connected to the cable 3 by means of the extrusion sleeve 24. For this purpose, both the plug connector 2 and the cable 3 are partially arranged inside the extrusion sleeve 24. A partial region of the extrusion sleeve 24 is extruded by the outer jacket 9 of the cable 3. In contrast, another partial region of the extrusion sleeve is extruded by the outer conductor sleeve 11. In the present embodiment, the shield 7 is widened and arranged between the extrusion region 25 of the extrusion sleeve 24 and the outer conductor sleeve 11. In this way, an electrically conductive connection is established between the outer conductor sleeve 11 and the shield 7. In addition to the extrusion region 25, the outer conductor sleeve 11 has an intermediate region 26, which is connected at the extrusion region 25 in the plug-in direction x. The inner conductors 4.1, 4.2 extend parallel to the plug-in direction x and at a distance from the outer conductor sleeve 11 through the extrusion region 25 and the intermediate region 26 up to the connection sections 14.1, 14.2 of the respective inner conductor contacts 12.1, 12.2. However, the inner conductors 4.1, 4.2 have a greater distance to the outer conductor sleeve 11 in the extrusion region 25 than in the intermediate region 26. This is achieved by the outer conductor sleeve 11 having a greater inner diameter in the extrusion region than in the intermediate region 26.

[0037] Figure 2 A three-dimensional view of an embodiment of the plug connector device 1 according to the application is shown. The plug connector 2 is connected to the cable 3 via the extrusion sleeve 24. The outer conductor sleeve 11 is surrounded by the collar element 22. The collar element 22 is made of plastic and has a fastening element 23. The plug connector 2 can be connected to a plug-in housing (not shown) by means of the fastening element 23.

[0038] Figures 3a to 3cEmbodiments of a cable 3 for a plug connector device according to the application are shown in different views. The inner conductors 4.1, 4.2 are exposed from the outer jacket 9 in an end section 10 of the cable 3, wherein the shield 7 surrounds both inner conductors 4.1, 4.2. The shield 7 is shortened and widened in a later, not shown process step, so that the inner conductors 4.1, 4.2 are also released from the shield 7 in the end section 10. The inner conductors 4.1, 4.2 are arranged parallel to each other and parallel to the plug-in direction x in the end section 10. Outside the end section 10, the inner conductors 4.1, 4.2 are twisted around each other. Furthermore, the inner conductors 4.1, 4.2 are arranged with their central axes on the main plane 16. Furthermore, the inner conductors 4.1, 4.2 are arranged with a wire spacing c and mirror-symmetrically to the symmetry axis 17 in the end section 10.

[0039] Figure 4a and Figure 4b Embodiments of a partially assembled cable 3 for a plug connector device according to the application are shown in different views. The cable 3 is electrically conductively connected with its inner conductors 4 to the inner conductor contact 12. The inner conductor contact 12 is divided into a plug-in section 13, a connection section 14 and a transition section 15, respectively. Here, the plug-in section 13 of the inner conductor contact 12 is arranged with its central axis on the main plane 16. The transition section 15 encloses an angle with the symmetry plane 17, the tangent function of which is equal to the result of the quotient, the minuend of which is formed by the difference between the first contact section spacing (a) and the second contact section spacing (b) and the divisor of which is formed by the double length (1) of the transition section (15). The length (1) of the transition section (15) is determined parallel to the plug-in direction (x).
