Description

Technical field

[0001] The present invention relates to a line arrangement for a vehicle. State of the art

[0002] A modern, electrically powered vehicle has a traction battery and a charging socket. The traction battery is electrically connected to the charging socket via a cable assembly. This cable assembly consists of a coaxial conductor with an inner conductor and an outer conductor. The inner conductor is electrically connected to the charging socket via a first connection element. The outer conductor is also electrically connected to the charging socket via a second connection element. The cable assembly is pre-assembled during vehicle assembly. Therefore, if unavoidable positional tolerances exist between the traction battery and the charging socket, the cable assembly must be manually adjusted to connect them.However, this causes mechanical stresses to build up in the entire cable assembly, which can lead to premature failure of the cable assembly during later operation of the vehicle.

[0003] A charging socket is disclosed in DE 10 2021 103 797 B3 and DE 10 2021 123 487 A1. Devices for electrically connecting electrical components are disclosed in DE 10 2022 120 946 A1 and DE 10 2021 117 009 B3. Description of the invention

[0004] The object of the invention is therefore to provide a cable arrangement for a vehicle that is easier to assemble and / or has a longer service life compared to the prior art.

[0005] This problem is solved by the features of the independent claim. Advantageous embodiments of the invention are specified in the dependent claims, the following description, and the figures.

[0006] According to the invention, a conductor arrangement for a vehicle, preferably for electrically contacting a traction battery of the vehicle with a charging socket of the vehicle, is proposed, comprising a first round conductor and a first plug system, wherein the first plug system has a connection element, wherein the connection element of the first plug system is in, preferably electrically conductive, material contact with a conductor section of the first round conductor, and wherein the connection element of the first plug system has a flexible section, preferably having a flexible and / or low bending stiffness.Preferably, the connection element of the first plug-in system comprises a contact section and / or a rigid conductor section. It is particularly preferred that the flexible section is more flexible and / or has a lower bending stiffness compared to the contact section and / or the rigid conductor section. Due to the flexible design of the flexible section, the first plug-in system can be easily adapted to tolerance deviations between the traction battery and the charging socket by bending the connection element with minimal force. The cable arrangement is therefore easier to assemble than known cable arrangements.Furthermore, by adapting the cable arrangement to the tolerance deviations through bending the connection element, no mechanical stresses are built up in the rest of the cable arrangement, so that the cable arrangement has a longer service life compared to known cable arrangements.

[0007] In particular, "flexible" or "having low bending stiffness" can be understood to mean that the flexible section of the first plug-in system and / or a second plug-in system of the cable arrangement is designed with regard to its material and / or its geometry in such a way that an end of the flexible section, which is facing away from the first round conductor, can be bent around the first round conductor in all three spatial directions with little effort, essentially without introducing a torsional and / or bending force into the first round conductor.

[0008] In order to connect both electrical poles of the traction battery to the charging socket using the cable arrangement, it is provided, by way of example, that the cable arrangement comprises a coaxial cable and a second plug system, and that the coaxial cable comprises the first round conductor and a second round conductor, wherein it is provided that a connection element of the second plug system is in, preferably electrically conductive, material contact with a conductor section of the second round conductor, and / or wherein it is provided that the first plug system is identical to the second plug system, and / or that the first plug system is arranged symmetrically, preferably rotationally symmetrically or plane-symmetrically, and preferably rotated about the coaxial conductor, relative to the second plug system on the coaxial conductor.

[0010] In order to realize the first flexible section of the first connecting element in a simple and cost-effective manner with low bending stiffness, an exemplary embodiment provides that the flexible section of the first plug-in system and / or the flexible section of the second plug-in system has a braid of one or more metal wires or a fabric, preferably a flat woven tape, of one or more metal wires, and / or that the flexible section of the first plug-in system and / or the second plug-in system has a flat conductor or several, preferably stacked, flat conductors or, preferably, stranded conductors arranged side by side.

[0011] To design the flexible section of the first plug-in system with low electrical resistance, it is provided, by way of example, that the material of at least one of the metal wires is aluminium or an aluminium alloy, and / or preferably that the material of at least one of the metal wires is copper or a copper alloy.

[0012] In order to ensure that the flat conductor or conductors have a relatively low bending stiffness, it is preferably provided that one or more or all of the flat conductors are shaped in a wave-like and / or meandering manner.

[0013] In order to achieve a particularly high current-carrying capacity of the braid, it is preferably provided, by way of example, that the braid has several interwoven bands, each of which has several metal wires.

[0014] To simplify the manufacture and handling of the connection element of the first plug-in system and / or the connection element of the second plug-in system, an exemplary embodiment provides that the connection element of the first plug-in system has a rigid conductor section of the first plug-in system which is electrically connected to the flexible section of the first plug-in system, and that the rigid conductor section of the first plug-in system, preferably a round conductor-side end face of the rigid conductor section of the first plug-in system, is directly in material contact with the outer circumferential surface of the first round conductor.

[0015] A rigid conductor section of a plug-in system can be understood as a section of a connection element of the plug-in system which has a significantly greater bending stiffness compared to the flexible section, which is preferably bonded with a material connection.

[0016] In order to ensure protection against contact with live components of the cable assembly, a preferred embodiment provides that the first plug-in system has a housing, preferably electrically insulating, and that the housing of the first plug-in system defines an interior space to the outside in which the conductor section of the first round conductor and the connection element of the first plug-in system are arranged, preferably completely, and / or that the second plug-in system has a housing, preferably electrically insulating, and that the housing of the second plug-in system defines an interior space to the outside in which the conductor section of the second round conductor and the connection element of the second plug-in system are arranged, preferably completely.

[0017] To simplify the mounting of the plug-in system onto the coaxial conductor, it is provided, by way of example, that the conductor arrangement has a connecting sleeve, wherein it is provided that a housing base section of the housing of the first plug-in system and a housing base section of the housing of the second plug-in system are connected to each other by means of the connecting sleeve.

[0018] In order to adapt the connecting sleeve to a straight and a curved path of the coaxial conductor, it is preferably provided that the material of the connecting sleeve is an elastomer, and / or that the connecting sleeve is mechanically flexible, preferably having the shape of a corrugated tube and / or a bellows.

[0019] In order to establish a reliable and easily accessible material connection between the connection element of the first plug-in system and the first round conductor, an exemplary embodiment provides that the flexible section of the first plug-in system, preferably substantially, and / or the rigid conductor section of the first plug-in system, preferably substantially, extends in a first connection element plane, wherein a longitudinal axis of the first conductor section extends in the first connection element plane, and / or wherein the flexible section of the first plug-in system is in material contact with the first round conductor, preferably the outer circumferential surface of the first round conductor, with the round conductor-side end face preferably extending substantially perpendicular to the first connection element plane.

[0020] Preferably, the connection element of the first plug-in system and the first cable section are arranged in an interior housing compartment, which is bounded externally by the housing of the first plug-in system. For example, the housing of the first plug-in system has a flexible housing section that is more flexible and / or has a lower bending stiffness compared to the other elements of the housing of the first plug-in system.

[0021] In order to achieve a high current-carrying capacity of the material connection between the first round conductor and the flexible section or the rigid conductor section, even with a small material thickness of the flexible section of the first plug-in system or the first rigid conductor section of the first plug-in system, an exemplary embodiment provides that the flexible section of the first plug-in system extends substantially in a first connection element plane, and that a longitudinal axis of the first conductor section extends parallel to and spaced apart from the first connection element plane, wherein it is preferably provided that a round conductor-side cover surface of the flexible section of the first plug-in system is in material contact with the outer circumferential surface of the first round conductor, wherein it is particularly preferably provided that the round conductor-side cover surface extends substantially parallel to the first connection element plane.

[0022] As an example, the first connector system is designed to have an overmolding made of electrically insulating and soft elastomer, such as polyurethane, and a plastic housing made of, for example, polyamide. The plastic housing surrounds only a portion of the contact section, while the overmolding surrounds the flexible section of the first connector system and a portion of the contact section. The plastic housing and the overmolding are bonded together in the area of ​​the contact section.

[0023] The invention also proposes a vehicle with a wiring arrangement as described above. Preferably, the traction battery is electrically connected to the charging socket via the wiring arrangement. Character description

[0024] Advantageous embodiments of the invention are explained in more detail below with reference to the accompanying figures.

[0025] They show: Fig. 1. A section of a pipe arrangement in a side view; Fig. 2. The line arrangement in a perspective view; Fig. 3. In a perspective view, the pipe arrangement is shown, with flexible sections of the pipe arrangement bent at right angles; Fig. 4. The pipe arrangement is shown in a sectional view from above; Fig. 5. The pipe layout is shown in a perspective side-section view; Fig. 6. The line arrangement in a perspective view; Fig. 7 to 12 each show further line arrangements in a perspective view.

[0026] In the Fig. Figure 1 shows a section of a wiring arrangement 1. The wiring arrangement can be part of a vehicle. A traction battery of the vehicle can be electrically connected to a charging socket of the vehicle by means of the wiring arrangement 1.

[0027] The conductor arrangement 1 comprises a coaxial conductor 3. The coaxial conductor 3 extends along a conductor path and includes a first round conductor 5 and a second round conductor 7. The material of the first round conductor 5 and the second round conductor 7 can each be aluminum or an aluminum alloy. The first round conductor 5 can extend radially inside the second round conductor 7 with respect to the conductor path and can be referred to as the inner conductor. The second round conductor 7 can extend radially outside the second round conductor 7 with respect to the conductor path and can be referred to as the outer conductor. The first round conductor 5 is electrically insulated from the second round conductor 7 by an insulating layer of the coaxial conductor 3.

[0028] The cable arrangement 1 comprises a first plug-in system A and a second plug-in system B, which, for illustrative purposes only, are identical in construction. The first plug-in system A comprises a connection element 11 and a housing 13. The connection element 11 has a rigid conductor section 15, which is essentially cuboid in shape, as well as a flexible section 17 and a contact section 19, which is also essentially cuboid in shape. The flexible section 17 is more flexible and / or has a lower bending stiffness compared to the rigid conductor section and the contact section. The rigid conductor section 15 extends essentially over a plane within a first connection element plane AE1 and is symmetrical to this plane.

[0029] The rigid conductor section 15, specifically a round-conductor end face of the rigid conductor section 15, is in a metallurgical bond with an outer circumferential surface of a conductor section LA1 of the first round conductor 5. The conductor section LA1 runs in a straight line and is rotationally symmetrical about a longitudinal axis L1 of the conductor section LA1. Furthermore, the connection element 11 extends radially outwards from the conductor section LA1 and with respect to the longitudinal axis L1 of the conductor section LA1. The round-conductor end face of the rigid conductor section 15 extends, preferably at least substantially, perpendicular to the first connection element plane AE1. The metallurgical bond is preferably produced by a welding or soldering process. Particularly preferably, the metallurgical bond can be produced, for example, by laser welding or ultrasonic welding.To create a high-current-carrying material connection, for example by means of a welding process, the conductor section LA1 can be flattened on the side facing the round-conductor end face of the rigid conductor section 15. Alternatively or additionally, the round-conductor end face of the rigid conductor section 15 can be convex in the direction away from conductor section LA1.

[0030] With a flex-section-side end face of the rigid conductor section 15, which faces away from the first round conductor 5, the rigid conductor section 15 is in a material connection with the flex section 17. With a contact-section-side end face of the flex section 17, which faces the contact section 19, the flex section 17 is in a material connection with the contact section 19. The contact section 19 is generally designed and / or suitable for being electrically connected to an electrical pole of an electrical component or another conductor arrangement via a plug and / or screw connection. In the Fig. 2. The contact section 19 has a sleeve-shaped contact element. A screw can be inserted through a screw opening that is bounded on the outside by the contact element, and the contact section 19 can be screwed to the electrical component or the further conductor arrangement by means of the screw.

[0031] As a general rule, the rigid conductor section 15 is purely optional as part of the connection element 11. Depending on the specific application of the conductor arrangement 1, the flexible section 17 can therefore also be in direct contact with the outer circumferential surface of the conductor section LA1, and not only indirectly via the rigid conductor section 15.

[0032] The flexible section 17 is flexible and has a comparatively low bending stiffness, particularly compared to the rigid conductor section 15 and / or the contact section 19. The flexible section 17 is designed to be flexible in such a way that tolerance compensation for positional and / or displacement between the traction battery and the vehicle's charging socket is possible by manual, preferably elastic, bending of the flexible section 17, largely without causing deformations and / or mechanical stresses in the remaining cable arrangement 1. Due to the flexible design of the flexible section 17, the first plug system A can be bent with minimal force from an unstuck state, as is the case, for example, in the Fig. 1 is shown, in a bent state, as is the case, for example, in the Fig. As shown in section 3, they will be transferred. In the Fig. 3 shows the wiring arrangement as merely an example of electrical contact with another wiring arrangement.

[0033] To be flexible with minimal force and exhibit low bending stiffness, the flexible section can be designed accordingly with regard to its geometry, dimensions, and / or material. In the Fig. In Figure 1, the flexible section 17, as just one of several exemplary possibilities for its flexible design, is shaped in a wave-like form, with wave troughs and wave crests. The flexible section 17 nevertheless extends at least substantially within the first connection element plane AE1, with the wave troughs and wave crests lying outside and / or adjacent to the first connection element plane AE1. Alternatively or additionally to the wave shape, the flexible section 17 can, as just one of several further examples, also comprise a braid of one or more metal wires or a fabric, preferably a flat woven tape, of one or more metal wires. The material of at least one of the metal wires can be aluminum or an aluminum alloy, or copper or a copper alloy.Alternatively or additionally, the flexible section 17 can have one or more flat conductors, preferably stacked at right angles to each other with respect to the first connection element level AE1.

[0034] The first connector system A has an interior housing that is sealed watertight to the outside by the rigid housing 13. The housing 13 also provides electrical touch protection for the conductor section LA1 and the connection element 11. The connection element 11 and the conductor section LA1 are arranged within the interior housing of the first connector system A. The housing 13 has a base section 33, a flexible section 35, and an end section 37. The base section 33 is connected to the end section 37 via the flexible section 35 and the flexible section 35 itself.

[0035] The housing flex section 35 is designed to be mechanically flexible such that, when the flex section 17 is bent, the housing flex section 35 adapts to the bent flex section 17. The material of the housing flex section 35 can be an elastomer, for example. Alternatively or additionally, the housing flex section 35 can, preferably substantially, have the shape of a corrugated tube and / or a bellows.

[0036] The housing 13 has a connection element passage 39, which is bounded externally by the housing base section 35. The connection element 11 extends from the part of the housing interior of the housing 13 that is substantially bounded externally by the housing base section 33 into the part of the housing interior of the housing 13 that is substantially bounded externally by the housing flex section 35.

[0037] The housing 13 has a first access opening 41, which is bounded externally by the housing base section 35. The material connection between the connecting element 11 and the first round conductor 5 can be established via the first access opening 41, for example by laser or ultrasonic welding. The housing 13 also has a first housing cover 43, which closes the first access opening 41.

[0038] The first housing cover 43 has a first fixing leg 45 and a second fixing leg 47. The first fixing leg 45 and the second fixing leg 47 are each chamfered and / or beveled at their tips. If the first access opening 41 is closed by the first housing cover 43, the first fixing leg 45 extends into the interior of the housing between the rigid conductor section 15 and a first side wall of the housing base section 33. The second fixing leg 47 also extends into the interior of the housing between the rigid conductor section 15 and a second side wall of the housing base section 33. The fixing legs 45 and 47 are each in contact with the rigid conductor section 15 and the housing base section 33, respectively.The housing base section 33 is fixed to the connection element 11 by means of the fixing legs 45 and 47 such that the housing 13, with the first housing cover 43 mounted, is fixed to the connection element 11 along the longitudinal axis L1 of the conductor section LA1. In the . Fig. 4 and Fig. Figure 5 shows the first fixation leg 45 and the second fixation leg 47 clearly.

[0039] Additionally, the housing 13 has a conductor passage that is bounded externally by the first side wall of the housing base section 33. The first round conductor 5 and the insulating layer project through the conductor passage into the part of the housing interior that is essentially bounded externally by the housing base section 33.

[0040] Furthermore, the housing 13 has a cover opening that is bounded by the second side wall of the housing base section 33. The cover opening is closed with a cover 49 of the conductor assembly 1. The cover 49 has a sleeve-shaped guide ring, wherein the outer circumferential surface of the first round conductor 5 is in contact with the inner circumferential surface of the guide ring, so that the first round conductor 5 is fixed in the interior of the housing via the guide ring.

[0041] Additionally, the housing 13 has a second access opening 51, which is bounded externally by the housing base section 33. The second access opening 51 is opposite the first access opening 41 and is closed by means of a second housing cover of the housing 13.

[0042] The second plug-in system B is identical in construction to the first plug-in system A, so that the first plug-in system A and the second plug-in system B are identical components. Consequently, plug-in system B also has a connection element 61, which is identical to the connection element 11 and extends essentially over a surface in a second connection element level AE2. The second connection element level AE2 is located in the Fig. Figure 7 is shown only as an example and indicated by a dash-dot line. In the second plug-in system B, however, the connecting element 61 is not in a material connection with the conductor section LA1, but instead with an outer circumferential surface of a conductor section LA2 of the second round conductor 7. The material connection between the connecting element 61 and the conductor section LA2 is identical to the material connection between the connecting element 11 and the outer circumferential surface of the conductor section LA1.

[0043] The second connector system B also has a housing 63, which is identical in construction to the housing 13 and fulfills the same function. The second connector system B has an interior space that is bounded externally by the housing 63. The housing 63 has a terminal element opening, a housing base section, a conductor opening, and a cover opening, each bounded externally by the housing base section and designed identically to those of the housing 13. The conductor opening of the housing 63 is opposite the conductor opening of the housing 13. The coaxial conductor 3 is inserted through the cover opening of the housing 63 into the part of the interior space of the second connector system B that is essentially bounded externally by the housing base section of the housing 63.The first round conductor 5 and the insulating layer are led out of the interior of the housing 63 towards the first plug-in system A via the conductor opening of the housing 63. Therefore, unlike the cover opening of the housing 13, the cover opening of the housing 63 is not closed by a cover.

[0044] The conductor assembly 1 additionally features a connecting sleeve 71. The housing 13 and the housing 63 are connected to each other in a watertight and flexible manner via the connecting sleeve 71. The connecting sleeve 71 is clamped to both the base section of the housing 13 and the base section of the housing 63. The connecting sleeve 71 can be manufactured as a single, single component made of a single material. The material of the connecting sleeve 71 can be an elastomer, and / or the connecting sleeve 71 can essentially have the shape of a corrugated tube and / or a bellows. The connecting sleeve 71 is rotatable around the first round conductor 5, both relative to the first connector system A and relative to the second connector system B. The design of the connector systems A and B and the connecting sleeve 71 allows for a variety of ways to arrange and align the connector systems A and B on the coaxial conductor 3.In cable arrangement 1, cable section LA1 extends coaxially to cable section LA2. The first connector system A and the second connector system B are identical in construction. As shown in the diagram... Fig. As shown in Figure 6, the second plug-in system B is arranged plane-symmetrically to the first plug-in system A on the coaxial conductor 3 about a plane of symmetry E.

[0045] Further selected conductor arrangements, which are at least partially identical to conductor arrangement 1, are described in the Fig. Figures 7 to 12 are shown. Unless explicitly stated otherwise, the above applies not only to line arrangement 1, but also to the other line arrangements.

[0046] In the Fig. Figure 7 shows a conductor arrangement 101. The conductor arrangement 101 is essentially identical to the conductor arrangement 1 and differs from the conductor arrangement 1 only in that the first connection element level AE1 and the second connection element level AE2 do not coincide, but are rotated relative to each other around the coaxial conductor 3, so that the first connection element level AE1 and the second connection element level AE2 together with the longitudinal axis L1 of the conductor section LA1 enclose an angle with an angular value of approximately 30°.

[0047] In the Fig. Figure 8 shows a cable arrangement 111. Cable arrangement 111 is essentially identical to cable arrangement 1. As with cable arrangement 1, cable section LA1 and cable section LA2 each extend in a straight line and in a common plane. Cable arrangement 111 differs from cable arrangement 1 only in that cable section LA1 does not run coaxially to cable section L2, but rather that the two cable sections LA1 and LA2 converge at a bend between the two connector systems A and B and together form an angle with a value of less than 180°.

[0048] In the Fig. Figure 9 shows a conductor arrangement 121. Conductor arrangement 121 is essentially identical to conductor arrangement 1 and differs from conductor arrangement 1 only in that the first connector system A and the second connector system B are not arranged plane-symmetrically, but rotationally symmetrically to each other about an axis of rotation on the coaxial conductor 3. The axis of rotation extends between the two connector systems A and B and intersects the longitudinal axis L1 of the conductor section LA1 at a right angle. In conductor arrangement 121, the first connection element level AE1 and the second connection element level AE2 coincide and extend at right angles to the axis of rotation.

[0049] In the Fig. Figure 10 shows a conduit arrangement 131. The conduit arrangement 131 is essentially identical to the conduit arrangement 121. The conduit arrangement 131 differs from the conduit arrangement 121 only in that the first connection element plane AE1 and the second connection element plane AE2 do not coincide, but together with the longitudinal axis L1 of the conduit section LA1 form an angle with a value of approximately 35°.

[0050] In the Fig. Figure 11 shows a cable arrangement 141. The cable arrangement 141 is essentially identical to the cable arrangement 1. The first plug system A has the terminal element 11, and the second plug system B has the terminal element 61. Plug systems A and B have a common housing and a common housing interior, which is bounded externally by the housing. The housing has a common housing base section 143, two housing flex sections, and two housing end sections. Each of the housing flex sections is identical to the housing flex section 35. Each of the housing end sections is identical to the housing end section 37. The cable section LA1 and the cable section LA2 are arranged in the part of the housing interior that is bounded externally, essentially, by the housing base section 143.The housing base section 143 limits both a connection element passage to the outside, associated with the connection element 11, and a connection element passage to the outside, associated with the connection element 61.

[0051] In the Fig. Figure 12 shows a conductor arrangement 201. The conductor arrangement 201 comprises the coaxial conductor 3 with conductor section LA1 and conductor section LA2, as well as a first connector system 203 and a second connector system 205. The first connector system 203 and the second connector system 205 are arranged side by side on the coaxial conductor 3.

[0052] The first connector system 203 has a flexible section 211 that is flexible and / or has low flexural stiffness, as well as a rigid contact section 213 that is stiffer than the flexible section 211. The flexible section 211 can be constructed identically or manufactured in the same way as the flexible section 15 of the conductor arrangements 1, 111, 121, 131, and 141. For illustrative purposes only, the flexible section 211 is formed by a braid of metal wires and is essentially plate-shaped. The flexible section 211 extends essentially flat within a single plane. The flexible section 211 has a round-conductor-side cover surface 215 that extends essentially parallel to the plane of the flexible section. The round-conductor-side cover surface 215 is in close contact with the outer circumferential surface of the conductor section LA1 at its end facing away from the conductor section LA1.The flexible section plane thus extends parallel and spaced apart from the longitudinal axis L1 of the line section LA1.

[0053] The round conductor-side cover surface 215 is in planar contact with contact section 213 at one end facing the contact section 213. Contact section 213 extends essentially in a plane parallel to the flex section plane. Contact section 213 has a sleeve-shaped contact element. The contact element defines a screw opening to the outside.

[0054] A screw can be inserted through the screw hole, and the contact section 213 can be screwed to an electrical component or to another conductor arrangement. In the area of ​​the contact element, the first plug-in system 203 is surrounded by a dimensionally stable plastic housing 217.

[0055] The first connector system 203 has an electrically insulating, dimensionally stable plastic housing 217 in the area of ​​the screw opening. The first connector system 203 and the cable section LA1 have a complete overmolding 219 made of electrically insulating and flexible elastomer outside the plastic housing. Due to the flexible design of the overmolding 219, it can adapt to deformations of the flexible section 211. If the flexible section 211 is deformed to compensate for tolerances, the overmolding 219 can adapt to this deformation. Electrical contact protection by the overmolding 219 is therefore ensured even when the flexible section 211 is deformed. The plastic housing 217 is bonded to the overmolding 219 in a material-bonded manner. REFERENCE MARK LIST 1.
