Description

Technical Field

[0001] The invention relates to a housing for a shielded electrical conductor and a conductor arrangement for insertion into such a housing. Furthermore, an electrical connector having a housing according to the invention and a conductor arrangement according to the invention inserted into the housing is the subject of the invention. Background Art

[0002] Electrical connectors are used to connect electrical conductors (such as busbars) to each other in an electrically conductive manner. The connector usually provides at least one electrical conductor that can be inserted and received in a housing. The electrical conductor usually has an electromagnetic shield. During operation, especially at high currents or voltages, currents or signals may occur in the shielding, which should be dissipated.

[0003] Providing such derivation is often accompanied by complex construction and a time-consuming connector assembly process, especially without automation. Summary of the invention

[0004] SUMMARY OF THE INVENTION Therefore, a problem underlying the present invention is to provide means for simplifying the construction and assembly of an electrical connector.

[0005] The problem is solved by a housing for a shielded electrical conductor, such as a bus bar, having:

[0006] a first receiving portion for a shielded electrical conductor, the shielded electrical conductor being insertable in a longitudinal direction of the first receiving portion from an open end of the first receiving portion,

[0007] a second receiving portion for a grounding conductor, the grounding conductor being able to be introduced into the second receiving portion through the opening and having a transition region extending in the longitudinal direction of the first receiving portion, the transition region being suitable for receiving an electrical contact element for connecting a shield of the shielded electrical conductor to the grounding conductor,

[0008] The second receiving portion is separated from the first receiving portion by at least one wall extending in the longitudinal direction of the first receiving portion.

[0009] By providing two separate receiving parts, a shielded electrical conductor and a ground conductor can be received separately from each other in the housing. On the one hand, this has the advantage of improving the guidance of the conductors in their respective receiving parts. On the other hand, it simplifies assembly and ensures a secure, low-backlash fit of the conductors in the housing. This ensures a particularly reliable electrical connection and prevents damage to the conductors.

[0010] The above invention can be further improved by the following features, each of which is preferred and can be combined with each other as desired.

[0011] The housing according to the invention can be part of the conductor arrangement mentioned in the introduction. For example, the ground conductor can also be adapted to be grounded and connected to the vehicle body. The ground conductor can also be used or adapted as a signal conductor, via which electrical signals, in particular electrical signals in the low voltage or low current range, can be transmitted. Furthermore, the ground conductor can have a connector suitable for contacting the contact element, such as a crimp connector or a lead. Possible examples of connectors that can be used are the MCP 6.3 and SCON6 connectors. Of course, other standardized or non-standardized connectors are also conceivable.

[0012] The shielded electrical conductor may have an insulator at least partially arranged between the shielded electrical conductor and the shield. The shape of the electrical conductor may also be substantially cylindrical, tubular or cuboid. Similarly, the shield and / or the insulator and / or one of the receiving parts may also be substantially cylindrical, tubular or cuboid. In particular, the electrical conductor, the insulator and the shield may be arranged coaxially with each other.

[0013] According to one configuration, the enclosure around the first receiving part or the housing section around the first receiving part can be sealed relative to the electrical conductor. The electrical conductor or the shielding part can be surrounded by a seal in a region, which seals the gap between the electrical conductor or the shielding part of the electrical conductor and the enclosure around the first receiving part or the housing section around the first receiving part.

[0014] The contact element may be Z-shaped and in particular have two sections arranged parallel to one another, which may extend at an angle, preferably at right angles, to another section of the contact element. For example, the contact element may also be flat and have a rectangular cross section. In one configuration, the contact element may be at least partially curved and thus have the shape of, for example, a hollow cylindrical shell section. The contact element may also have a configuration complementary to a wall of the housing or to an enclosure of the housing.

[0015] According to a preferred embodiment, the contact element can be inserted into the housing. In addition, embedding of the contact element in the housing can be provided. This configuration allows the contact element to be fixed relative to the housing, which simplifies the assembly of the shielded electrical conductor with the housing. In particular, the contact element can be fixed captively.

[0016] In one configuration, the contact element may be part of the housing.

[0017] According to another aspect, in order to make the contact element more accessible for contacting the ground conductor and / or the shield, the contact element may protrude from the housing into the first receiving portion and the second receiving portion.

[0018] The contact element may, for example, protrude from the enclosure of the housing, in particular in the transition region. The portion of the housing from which the contact element protrudes into the first receiving portion and the second receiving portion may be the portion of the housing into which the contact element is inserted. The contact element may extend at least partially perpendicular to the wall of the housing, the enclosure of the first receiving portion, or the longitudinal direction of the first receiving portion, or the longitudinal direction of the second receiving portion. In particular, a section of the contact element may extend along the longitudinal direction of the first receiving portion, and / or another section of the contact element may extend along the longitudinal direction of the second receiving portion.

[0019] In one aspect, the contact element can have a plug contact which is adapted to contact the ground conductor at the end protruding into the second receiving portion. This configuration makes it possible to easily and reliably establish contact between the contact element and the ground conductor. This reduces the assembly effort and improves the quality of the electrical connection.

[0020] The end of the contact element protruding into the second receiving portion can be designed as a plug contact. In particular, standardized plug contacts can be used. The plug contact can be designed, for example, as a contact lug, a crimping cable lug, a tubular cable lug or a compressed cable lug. In addition, the plug contact can be flat and is therefore suitable, for example, as a flat conductor.

[0021] In order to further improve the quality of the electrical connection between the contact element and the shield, according to another preferred embodiment, the contact element can be configured at one end as a contact spring protruding into the first receiving portion. For example, the contact spring can be a crown spring.

[0022] The contact spring may be elastically deflectable, in particular radially outwards, and adapted to exert a contact force on the shielded electrical conductor. The contact force may act radially inwards or in the direction of the center of the first receiving part and may, for example, be a normal contact force. The contact spring may be elastically deflected by the shielded electrical conductor held in the first receiving part and / or deflected radially outwards or in a direction away from the center of the first receiving part. The contact force may be caused by a restoring force of the contact spring that counteracts the deflection.

[0023] In one configuration, the contact spring may extend at least partially in the circumferential direction of the first receiving portion. In addition, the contact spring may be at least partially complementary to the electrical conductor and / or the shielding of the electrical conductor and / or the wall of the housing and / or the surrounding portion of the first receiving portion.

[0024] According to another preferred embodiment, the second receiving portion can be closed to the ground conductor in the transition area. In particular, the ground conductor may not protrude into the first receiving portion. In addition, the housing can be adapted so that there is no passage between the first receiving portion and the second receiving portion, or at least no passage open to the ground conductor. In one embodiment, the second receiving portion can be open to the contact element only in the transition area. In addition, the transition area for the ground conductor can be closed by a portion of the housing or wall in which the contact element is inserted and / or in which the contact element is embedded.

[0025] According to another aspect of the invention, the longitudinal direction of the second receiving portion can extend parallel to the longitudinal direction of the first receiving portion or at a right angle, an obtuse angle or an acute angle. Due to these configurations, the geometry of the housing can be flexibly adapted to the space requirements or restrictions of various installation situations, in particular certain conductor exit directions. According to one embodiment, the first receiving portion and the second receiving portion can be arranged parallel to each other in terms of radius.

[0026] In a preferred embodiment, the contact element can be at least partially overmolded by the housing. This allows the contact element to be firmly fixed in the housing, which simplifies the contact of the contact element with the ground conductor and / or the shield and improves the quality of the electrical connection. In addition, due to the easily automated injection molding process, the manufacturing costs of the housing can be reduced.

[0027] The housing can be injection molded, in particular completely injection molded. Furthermore, the contact element can be completely overmolded by the housing. The overmolding of the contact element can be achieved by an insert molding process. In one configuration, the housing part forming the overmolding can be arranged in the transition region. Furthermore, the wall of the housing can represent and / or include the housing part forming the overmolding.

[0028] According to another preferred embodiment, the first receiving portion may have a protrusion extending in its longitudinal direction, along which the contact element can be inserted. Such a housing enables an electrical contact element to be received, which extends further outwards than the first receiving portion relative to the radial direction. In addition, the protrusion helps to protect and / or guide the contact element.

[0029] In one configuration, only a portion of the contact element may be inserted along the projection.The contact element and / or a portion of the contact element may protrude outwardly or away from the center of the first receiving portion, in particular in a radial direction.

[0030] The projection can be adapted to complement the contact element or a portion of the contact element that can be inserted along the projection. The projection can be configured as a slot or in the shape of a hollow cylindrical section. According to one configuration, the projection is only slightly wider than the contact element or the portion of the contact element that can be inserted along the projection in the circumferential direction of the first receiving portion. In particular, the projection can be configured so that the contact element or a portion of the contact element does not move or only moves slightly in the circumferential direction of the first receiving portion.

[0031] According to another preferred embodiment, the housing can have a third receiving portion for a further electrical conductor, which is connected to the first receiving portion at a second end arranged opposite to the open end in the longitudinal direction of the first receiving portion. This configuration increases the application range of the housing according to the present invention. In particular, such a housing can be used to receive a shielded electrical conductor, which will be connected to an electrical infrastructure or electrical equipment via a further electrical conductor.

[0032] The longitudinal directions of the first receiving portion and the third receiving portion may be at an angle of 90° to each other. In addition, the longitudinal directions of the first receiving portion, the second receiving portion and the third receiving portion may be located in a common plane. According to another configuration, the longitudinal direction of one receiving portion may extend at right angles to the longitudinal directions of the other two receiving portions.

[0033] The shielded electrical conductor and the further electrical conductor may be electrically connected and / or connectable to each other in the housing, for example at the transition between the first receiving portion and the third receiving portion or in the first receiving portion or the third receiving portion. The shielded electrical conductor may lead to a flange section, via which the electrical conductor can be fastened to the further housing using a fastening device. Examples of such fastening devices are bolts or screws. Furthermore, the fastening device may be at least partially received in the third receiving portion.

[0034] The further electrical conductor may be configured as a socket or a fastening device. The third receiving portion may have an enclosure, the housing being able to be plugged together with the further housing or connected to the further housing via the end of the enclosure. For example, the further housing may be part of a battery system.

[0035] The problem mentioned in the introduction is further solved by a conductor arrangement according to the invention for insertion into a housing, wherein the shielded electrical conductor has a shield which provides a contact point arranged at the level of the transition region with respect to the longitudinal direction of the first receiving part, via which the shield can be connected to the contact element. Providing such a contact point is preferred in terms of a reliable and high-quality electrical connection between the shield and the contact element.

[0036] The contact point can be located on or is a bare shield and in particular extends along the circumferential direction of the first receiving portion. The contact point preferably extends completely but at least partially along the shield of the electrical contact element. The contact point can also be cylindrical, cylindrical shell-shaped or cylindrical shell section-shaped.

[0037] In a preferred configuration, the conductor arrangement may have an electrically conductive socket resting on the shield at the contact point.The provision of a socket is cost effective and in terms of assembly is a simple way of enabling the shield of the electrical conductor to be brought into contact with the contact element.

[0038] The conductive socket may be, for example, a crimp socket, a crimp sleeve, a crimp ferrule, a simple sleeve or a shielding sleeve.

[0039] The socket may be attached to the shield, which is plugged, placed, clamped and / or fastened. The socket may be attached to the shield by plastic deformation (e.g. by crimping). The socket may protrude radially outward from the shield or away from the center of the first receiving portion.

[0040] Preferably, the socket can be attached at the contact point or on the shield without orientation. The fact that it can be attached without orientation can mean that the relative alignment of the socket with respect to the circumferential direction of the shield or the electrical conductor is irrelevant during assembly.

[0041] According to a further preferred embodiment, the socket can be provided with a contact element. In this way, the number of individual components of the conductor arrangement is reduced, which contributes to reducing production costs and simplifying assembly.

[0042] Preferably, the socket is mechanically and electrically connected to the contact element. The contact element may also be attached to the socket by fastening means and / or be formed integrally with the socket. The contact element may extend outwardly from the socket or from a portion of the socket not comprising the contact element, or extend away from the center of the first receiving portion, for example radially. The socket may be configured such that the contact element of the socket contacts the ground conductor only when it is fully assembled.

[0043] The above-mentioned problem is further solved by an electrical connector having a housing according to the invention and a conductor arrangement according to the invention inserted into the housing. The conductor arrangement can also be inserted, plugged into or received in the housing. The electrical connector can be easily and automatically assembled and meets a wide variety of requirements, in particular with regard to the installation space available for installation and different conductor outlet directions.

[0044] According to a preferred configuration, the electrical connector may have a ground conductor connected to the contact element in the transition region. The ground conductor may also be connected to the shield of the electrical conductor. The electrical connector according to this configuration can reliably discharge current occurring in the shield.

[0045] In the following, the present invention is explained in more detail by means of embodiments with reference to the accompanying drawings. In this case, if the technical effect associated with each feature present in the following embodiments is not important according to the above embodiments, the feature can be omitted.

[0053] In the following, reference Figures 1 to 4 The structure of the housing is described by way of example.

[0054] The housing 1 has a first receiving portion 2 and a second receiving portion 4. The second receiving portion 4 is separated from the first receiving portion 2 by at least one wall 8 extending along the longitudinal direction 6 of the first receiving portion 2. Figure 1 In the embodiment shown, the wall 8 is formed by a beam-shaped housing section 12 which extends along the longitudinal axis 6 of the first receiving part 2 and along a radial direction 10 of the first receiving part 2 .

[0055] exist Figure 1 In the illustrated configuration, the first receiving portion 2 and the second receiving portion 4 are substantially cylindrical and their longitudinal directions 6, 14 extend parallel to each other. Figure 2 and Figure 3 In the embodiment shown, the longitudinal direction 14 of the second receiving portion 4 may also extend at right angles to the longitudinal direction 6 of the first receiving portion 2, such as Figure 2 As shown, or extending at an acute angle, as Figure 3 According to another embodiment, the angle between the longitudinal direction 6 of the first receiving part 4 and the longitudinal direction 14 of the second receiving part 4 may also be an obtuse angle. In addition, at least one of the receiving parts 2, 4 may have a shape other than a columnar shape, such as a substantially cuboid shape.

[0056] The first receiving part 2 has an open end 16 through which the first receiving part 2 is accessible from outside the housing 1. For example, a shielded electrical conductor 18 can be inserted into the first receiving part 2 via the open end 16 along the longitudinal direction 6 of the first receiving part 2 and at least partially received therein.

[0057] The housing 1 further comprises a transition region 20 adapted to receive an electrical contact element 22 (eg Figure 4 The transition region 20 extends along the longitudinal direction 6 of the first receiving portion 2 and is as shown in FIG. Figure 1 and Figure 4 As shown, as an example, there may be a passage 24 between the first receiving part 2 and the second receiving part 4, or it may be formed by the passage 24. In particular, the second receiving part 4 may open into the first receiving part 2.

[0058] The second receiving portion 4 has an opening 26, through which the second receiving portion 4 can be accessed from outside the second receiving portion 4 or from outside the housing 1. The second receiving portion 4 is suitable for receiving a grounding conductor 28, which can be inserted into the second receiving portion 4 through the opening 26 along the longitudinal direction 14 of the second receiving portion 4.

[0059] According to one possible configuration, the second receiving portion 4 can be closed to the ground conductor 28 in the transition region 20. Thus, the ground conductor 28 can be received in the second receiving portion 4, but it cannot protrude into the first receiving portion 2 in the transition region 20 or above or through the transition region 20.

[0060] The housing 1 may further include a third receiving portion 30 connected to the first receiving portion 2 at a second end 32 of the first receiving portion 2. The second end 32 of the first receiving portion 2 is opposite to the open end 16 of the first receiving portion 2 relative to the longitudinal direction 6 of the first receiving portion 2. Figure 1-3 In the embodiment shown, the third receiving portion 30 has a substantially cylindrical shape, and the longitudinal direction 34 of the third receiving portion 30 extends at right angles to the longitudinal direction 6 of the first receiving portion 2 and at right angles to the longitudinal direction 14 of the second receiving portion 4. In particular, the longitudinal directions 6, 14, 34 of the first receiving portion 2, the second receiving portion 4 and the third receiving portion 30 are located Figure 1 in a common plane in the embodiment shown.

[0061] The third receiving portion 30 may be adapted to receive a further electrical conductor 36. Figure 1As can be seen in FIG. 2 , the further electrical conductor 36 can be configured as an electrically conductive fastening element 38 , which can be in electrically conductive contact with the shielded electrical conductor 18 received in the first receiving portion 2 .

[0062] In addition, another electrical conductor 36 or a conductive fastening element 38 can be inserted into the third receiving portion 30 via the upper opening 40 of the third receiving portion 30. In addition, the third receiving portion 30 can have a lower opening 42, which can be opposite to the upper opening 40 with respect to the longitudinal direction 34 of the third receiving portion 30. At the lower opening 42, as shown in FIG. Figure 3 As shown, the housing 1 can be connected or plugged together with a further housing 44. The further housing 44 can be, for example, part of a battery or a battery system, in particular a battery or a battery system of a vehicle.

[0063] Furthermore, an electrical contact element 22 can be inserted into the housing 1. Figure 4 In the embodiment of the present invention, the electrical contact element 22 is partially overmolded by the housing, wherein an overmolded region 46 of the electrical contact element 22 is located in the transition region 20. In this embodiment, the second receiving part 4 is separated from the first receiving part 2 by the electrical contact element 22 and a portion 48 of the housing 1 that forms the overmolding of the electrical contact element 22. The portion 48 of the housing 1 that forms the overmolding can be part of the wall or wall 8.

[0064] According to another configuration, there may be a gap 50 between the electrical contact element 22 inserted into the housing 1 and the housing 1, in particular in the transition region 20. The gap 50 may extend along the longitudinal direction 6 of the first receiving part 2 and perpendicularly to the longitudinal direction 6 of the first receiving part 2. Thus, the electrical contact element 22 is particularly movable or displaceable in the transition region 20.

[0065] exist Figure 4 In the embodiment shown, the electrical contact element 22 received in the transition region 20 protrudes from the housing 1 into the first receiving portion 2 and the second receiving portion 4. At its end 52 protruding into the second receiving portion 2, the electrical contact element 22 according to this configuration has a plug-in contact 54 which is suitable for contacting the grounding conductor 28 which can be received in the second receiving portion 4. Figure 4 It can further be seen in FIG. 4 that the plug-type contacts 54 of the electrical contact element 22 , which are configured as flat contacts, extend along the longitudinal direction 14 of the second receptacle 4 .

[0066] Furthermore, the electrical contact element 22 can be configured as a contact spring 58 at its end 56 protruding into the first receiving part 2. In the embodiment shown, the end 56 protruding into the first receiving part 2 or the contact spring 58 extends substantially along the longitudinal direction 6 of the first receiving part 4. Figure 4In the embodiment shown in FIG. 2 , by way of example, the contact spring 58 has approximately the shape of a cylindrical shell segment, which is adapted to complement an outer contour 60 of a shielded electrical conductor 18 which can be received in the first receptacle 2 .

[0067] exist Figure 4 In the illustrated embodiment, the contact spring 58 further comprises contact bends 64 arranged parallel to one another along the longitudinal direction 6 of the first receiving portion 2 and along the circumferential direction 62 of the first receiving portion 2, the contact bends 64 protruding in the direction of the center 66 of the first receiving portion 2. The contact bends 64 may be configured to contact the shielded electrical conductor 18 received in the first receiving portion 2.

[0068] The contact spring 58 can also be configured to be elastically deflected perpendicularly to the longitudinal direction 6 of the first receiving part 2 or to be elastically deflected outwardly in the radial direction 10, i.e., to be elastically deflected away from the center 66 of the first receiving part 2. In this way, the contact spring 58 can generate a restoring force in the direction opposite to the deflection, which can be generated inwardly on the shielded electrical conductor 18 received in the first receiving part 2 in the radial direction 10 or in the direction of the center 66 of the first receiving part 2.

[0069] According to one configuration, the first receiving part 2 may have a projection 68 (not visible), along which the electrical contact element 22 or at least a portion of the electrical contact element 22 may be inserted into the first receiving part 2. The projection 68 extends along the longitudinal direction 6 of the first receiving part 2 and may be recessed into a wall 70 of the first receiving part 2.

[0070] In the following, reference Figure 4 and Figure 5 The structure of the conductor arrangement 72 is explained by way of example.

[0071] The conductor arrangement 72 includes an electrical conductor 18 and a shield 74. In the example shown, the electrical conductor 18 is configured as a substantially cylindrical bus bar 76, which is partially coaxially surrounded by the substantially cylindrical shield 74. An insulator 78 may be arranged between the shield 74 and the shielded electrical conductor 18, by which the electrical conductor 18 is electrically decoupled from the shield 74.

[0072] The shield 74 provides a contact point 80 via which the shield 74 can be connected to the electrical contact element 22. When the conductor arrangement 72 is fully inserted into the housing 1, in particular into the first receiving part 2 of the housing 1, the contact point 80 is at the level of the transition region 20 relative to the longitudinal direction 6 of the first receiving part 2.

[0073] exist Figure 4In the embodiment shown, the conductor arrangement 72 has an electrically conductive socket 82 which rests on the shield 74 at the contact point 80. In the case shown, the socket 82 completely surrounds the shield 74 of the electrical conductor 18 along the circumferential direction 62.

[0074] As in accordance with Figure 5 As can be seen in the embodiment of the conductor arrangement 72 of the housing 1, the socket 82 can be provided with an electrical contact element 22. In this case, the electrical contact element 22 is configured as a contact fin 84 extending away from the center 66 of the first receiving part 2 of the housing 1 or extending outwardly in the radial direction 10. In order to insert the conductor arrangement 72 into the first receiving part 2 of the housing 1, the housing 1 can have the projection 68 already described.

[0075] from Figure 5 8, the conductor arrangement 72 may also have a seal 86 which may be adapted to seal the conductor arrangement 72 inserted into the first receiving portion 2 of the housing 1 relative to the housing 1. In the embodiment shown, the seal 86 is configured as a radial seal which extends coaxially or concentrically around the longitudinal direction 85 of the electrical conductor 18 or the longitudinal direction 87 of the shield 74.

[0076] Reference below Figure 4 The structure of the electric connector 88 according to the present invention is explained.

[0077] The electrical connector 88 has a housing 1 according to the invention and a conductor arrangement 72 according to the invention which is inserted into the first receptacle 2 of the housing 1 .

[0078] Figure 4 An example of a housing 1 with three receiving parts 2, 4, 30 is shown, the longitudinal directions 6, 14, 34 of the receiving parts 2, 4, 30 being located in a common plane. Furthermore, the longitudinal directions 6, 14 of the first receiving part 2 and the second receiving part 4 extend parallel to each other. The housing 1 has an electrical contact element 22, which is overmolded by the housing 1 and protrudes from the housing 1 in the transition area 20 of the housing 1 into the first receiving part 2 and the second receiving part 4.

[0079] The end 56 of the electrical contact element 22 protruding into the first receiving part 2 extends along the longitudinal direction 6 and the circumferential direction 62 of the first receiving part 2. The end 52 of the electrical contact element 22 protruding into the second receiving part 2 is configured as a flat plug contact 54, which extends along the longitudinal direction 6 of the second receiving part 2. The plug contact 54 is connected or plugged together with the grounding conductor 28 in the second receiving part 2, and the grounding conductor 28 is received in the second receiving part 2 along the longitudinal direction 14 of the second receiving part 2. The cable 90, which can be a component of the exemplary grounding conductor 28, can be connected to a ground potential, for example to the body of the vehicle.

[0080] The conductor arrangement 72 of the illustrated embodiment has a shielded electrical conductor 18 and an electrically conductive socket 82, which is arranged at the contact point 80 and rests on the shield 74. The socket 82 shown extends completely around the shield 74 of the electrical conductor 18 relative to the circumferential direction 62 of the first receiving part 2. The conductor arrangement 72 is inserted into the housing 1 so that one end of the electrical conductor 18, which is configured as a flange section 92, protrudes through the second end 32 of the first receiving part 2 into the third receiving part 30. In the third receiving part 30, the electrical conductor 18 is connected via the flange section 92 to the electrically conductive fastening element 38 received in the third receiving part 30. In the illustrated embodiment, the fastening element 38 is connected to a mating contact 94 arranged in the further housing 44.

[0081] exist Figure 4 In the embodiment shown, the shield 74 is conductively connected to the electrical contact element 22 via a socket 82 resting on the contact point 80. In particular, the end 56 of the electrical contact element 22, which is configured as a contact spring 58 and protrudes into the first receiving portion 2, contacts the socket 82. The illustrated contact spring 58 is configured in the shape of a cylindrical shell segment and is therefore complementary to the cylindrical exterior of the socket 82.

[0082] During operation of the electrical connector 88, current may flow through the shielded electrical conductor 18, so that current and / or signals may appear in the shield 74 of the electrical conductor 18. These currents and / or signals can be released from the shield 74 via the grounding conductor 28 connected to the shield 74 of the electrical conductor 18. For this purpose, the current first flows from the shield 74 into the socket 82 via the contact point 80 or at the contact point 80, and is then transmitted to the electrical contact element 22 via the contact spring 58 in contact with the socket 82. Subsequently, the current is introduced into the grounding conductor 28 connected to the electrical contact element 22 via the end 52 of the contact element 22, which protrudes into the second receiving portion 4 and is exemplarily configured as Figure 3 Plug contacts 54 in.
