Description

[Technical Field]

[0001] The present invention relates to a high current and / or high voltage assembly connector for an electric energy storage device of a vehicle assembly, particularly an electric vehicle. Further, the present invention relates to a power electrical assembly of a vehicle, particularly an electric energy storage device of an electric vehicle, and to a vehicle, particularly an electric vehicle. [Background technology]

[0002] In land-based power engineering and related more advanced electrical fields (electrical science, electrical engineering, power engineering, etc.), numerous electrical connectors are known that serve the purpose of transmitting currents and voltages in the high current and / or high voltage range. In this case, connectors for supplying and / or distributing electrical energy for short periods and / or permanently, for example, in warm, possibly hot, polluted, humid, and / or chemically reactive environments, ensure trouble-free transmission of electrical energy. Due to the wide range of applications, numerous such line connectors are known in the non-automotive and automotive fields.

[0003] Such high current and / or high voltage connectors can be installed, for example, in power electrical assemblies, such as (traction) batteries or battery modules, inverters, switchgear assemblies, etc. Efforts to reduce high fuel costs and environmental impacts, for example in the automotive field, necessitate hybrid or electric vehicles. One aspect of these vehicles is the handling of high charging and / or operating currents and / or voltages, and the relevant components of the vehicle's assemblies must be designed accordingly. This relates, for example, to high current or high voltage lines (e.g., stranded wires, conductor bars, bus bars, etc. made of copper or aluminum) and contact devices of connectors (e.g., terminal fittings, flat contacts, bus bars, etc. made of copper or aluminum).

[0004] Power electromechanical screw contact connections that meet stringent requirements can be used to electrically contact high current and / or high voltage connectors within power electrical assemblies. Such high current and / or high voltage screw contact connections allow for functional separation of the mechanical path from the electrical path. The mechanical path functions to transmit mechanical tensile stresses in the screw fastener, particularly a steel-to-steel screw fastener, while the electrical path is used as a low-resistance electrical contact connection, particularly a copper-to-copper connection, of the screw contact connection. Summary of the Invention [Problem to be solved by the invention]

[0005] The result is a high-current and / or high-voltage screw contact connection that is robust and easily handled in a typical manufacturing environment. Additionally, such a screw contact connection is easily separable (for diagnostics and reuse) while simultaneously being safe to contact. Such a screw contact connection can be used in a variety of ways and flexibly to contact battery modules and for other connection points in various termination panels of a power architecture. Efforts are continually being made to improve high-current and / or high-voltage connectors, particularly to design them more efficiently and, in the process, to increase cost efficiency. It is therefore an object of the present invention to provide an improved high-current and / or high-voltage connector for assembly in vehicles, particularly electric vehicles. [Means for solving the problem]

[0006] The object of the present invention is realized by a high current and / or high voltage assembly connector (hereinafter simply assembly connector) for an assembly of a vehicle, in particular an electric energy storage device of an electric vehicle, by a power electrical assembly of a vehicle, in particular an electric energy storage device of an electric vehicle, and by a vehicle, in particular an electric vehicle. Advantageous developments, additional features and / or advantages of the invention can be gathered from the dependent claims and the following description.

[0007] The assembly connector, for example formed as a header, is configured on the one hand to be mountable or to be mounted on the assembly wall, and on the other hand is configured such that, in the mounted state on the assembly wall, a connector shield of the assembly connector is conductively connected to the assembly wall, the conductive connection of the connector shield to the conductive layer of the assembly wall being made by a conductive shield contact adapter of the assembly connector.

[0008] That is, the conductive connection of the shield to the assembly wall is not made directly, but indirectly through the shield contact adapter. Of course, it will be clear from the term "adapter" that this is the intended predetermined physical configuration of the component, and not a shape that it takes due to actual circumstances, such as the shape of a coating or the like.

[0009] When the assembly connector is attached to the assembly wall, the conductive connection of the connector shield to the conductive layer of the assembly wall may be formed, on the one hand, as a direct electrical contact between the connector shield and the shield contact adapter, and / or, on the other hand, as a direct or indirect electrical contact between the shield contact adapter and the conductive layer of the assembly wall.

[0010] The direct electrical contact between the connector shield and the shield contact adapter can be formed as an electrical plug-in connection, an electrical contact connection, and / or an electrical spring connection. Here, at least one contact partner of the electrical contact can be formed as an electrical spring contact. Furthermore, the direct electrical contact can be formed by electrical contact lugs on the connector shield or the shield contact adapter. Furthermore, the direct electrical contact can be formed by spring contact lugs on the connector shield and the radially inner or outer side of the connector shield.

[0011] Direct electrical contact between the shield contact adapter and the conductive layer of the assembly wall can be made by a coating-opening device of the shield contact adapter. For example, such a coating-opening device can be a cutting, tearing, or breaking device, such as a blade, edge, corrugation, shoulder, or the like, that can cut through the coating of the assembly wall down to the conductive layer. Alternatively or additionally, direct electrical contact between the shield contact adapter and the conductive layer of the assembly wall can be made as an electrical plug-in connection, an electrical surface connection, and / or an electrical press-fit connection.

[0012] An indirect electrical contact between the shield contact adapter and the conductive layer of the assembly wall may be made by a clamping means that clamps the shield contact adapter against the assembly wall.

[0013] When the assembly connector is attached to the assembly wall, a substantially peripheral electrical peripheral contact can be formed between the connector shield and the shield contact adapter in the circumferential direction of the assembly connector to conductively connect the connector shield to the conductive layer of the assembly wall via the shield contact adapter, and the peripheral contact is preferably formed as intermittent electrical contact with a number of individual electrical contacts.

[0014] In order to electrically connect the connector shield to the conductive layer of the assembly wall via the shield contact adapter in the mounted state of the assembly connector relative to the assembly wall, electrical axial contacts can be arranged in the axial direction of the assembly connector between the shield contact adapter and the conductive layer of the assembly wall, the axial contacts being preferably formed as a number of axially pressed areas (points, sections) and / or as a number of axially extending hollow cylindrical contacts (with flat, corrugated or sawtooth boundary surfaces), where (see also above) preferably plural is less than many.

[0015] In a mounted state of the assembly connector relative to the assembly wall, the shield contact adapter can be attached to the inside of the assembly wall. That is, the shield contact adapter is mounted or mountable within the assembly. Furthermore, in the mounted state, a portion of the assembly connector inside the assembly can extend through the shield contact adapter, or at least an axial portion of the portion of the assembly connector inside the assembly can be disposed in the shield contact adapter. Furthermore, in the mounted state, a portion of the assembly connector outside the assembly can be mounted outside the assembly wall.

[0016] If the shielding contact adapter is formed as a ring-shaped shielding contact adapter (see below), the inner part of the assembly can extend through the connection through-opening. If the shielding contact adapter is formed as an apron-like shielding contact adapter (see also below), the inner part of the assembly can extend through the connection through-opening or can be arranged in the connection through-opening at least in its axial portion.

[0017] The shielding contact adapter may include a plate-shaped base, via which the shielding contact adapter can be fastened or is fastened to the assembly wall. Furthermore, the shielding contact adapter may be formed as a ring-shaped or apron-shaped shielding contact adapter that is substantially closed in the circumferential direction. Furthermore, the shielding contact adapter may include a connection through-opening, in which a portion of the assembly connector inside the assembly can be arranged or is arranged.

[0018] The shield contact adapter may include a centering ring that protrudes in the axial direction to position the shield contact adapter in the connector through-opening in the assembly wall. Furthermore, the shield contact adapter may include a peripheral wall that protrudes in the axial direction and is completely closed to prevent liquid from entering the interior of the shield contact adapter. The centering ring and the peripheral wall may be positioned on the shield contact adapter in the same plane in the axial direction. Furthermore, the peripheral wall may have a larger axial extent than the centering ring.

[0019] In the mounted state of the assembly connector relative to the assembly wall, the shield contact adapter can be fastened to the assembly wall by a fastening means. In particular, the fastening means can be formed as a screw or a rivet, in particular an SPR rivet (self-piercing rivet). In this case, the fastening means can penetrate the assembly wall and be fixedly arranged in a housing of the assembly connector. The housing can be formed as an outer housing of a part of the assembly connector outside the assembly.

[0020] In the mounted state of the assembly connector relative to the assembly wall, the shield contact adapter can be disposed around the connector through opening in a liquid-tight manner relative to the assembly wall by pressing the shield contact adapter against the assembly wall. Further, alternatively or additionally, a sealing material, seal, or the like can be used.

[0021] The shielding contact adapter can be configured as a shielding contact adapter for a multipolar, in particular a bipolar, connector assembly. Furthermore, the shielding contact adapter can include an elongated receiving area for each contact means of the connector assembly. Furthermore, the receiving areas for directly adjacent contact means in the cross section of the connection through-opening can include a constriction between them.

[0022] The shield contact adapter is preferably formed as a three-dimensional part. Furthermore, the shield contact adapter can be formed as a reattachable and detachable shield contact adapter. Furthermore, the shield contact adapter can be formed as a die-cast part, in particular an aluminum die-cast part, a deep-drawn part, or can be formed by a different method.

[0023] The assembly connector is preferably formed as an assembly connector device. Furthermore, the conductive layer of the assembly wall can include a coating of the assembly wall. Here, the coating can be configured to be conductive or non-conductive. The coating can be configured as a coating for the vehicle floor, in particular as a CDC coating (CDC: cathodic dip coating). Furthermore, the assembly wall can be formed as an assembly base wall.

[0024] The power electric assembly according to the invention, in particular the electrical energy storage device, comprises an assembly connector according to the invention in an assembly wall of the assembly. This kind of assembly can further be formed, for example, as an electric motor, an electric traction motor, an inverter, a switchgear assembly, etc., in particular for a vehicle. Furthermore, the energy storage device can be formed as a (traction) battery, a rechargeable battery, etc. Furthermore, the invention can be used, for example, when walls formed from sheet metal and / or aluminum die-cast parts can be used.

[0025] A vehicle according to the present invention comprises a power electric assembly according to the present invention. A vehicle is preferably understood to mean a motor vehicle, in particular a road vehicle, but can also be understood to mean a rail vehicle, a ship, and / or an aircraft. Furthermore, an electric vehicle is understood to mean a vehicle including an electric traction motor, which may include, in addition to the electric traction motor, a further non-electric drive device, such as, for example, an internal combustion engine. In other words, a vehicle including an electric traction motor can be understood to mean, for example, a hybrid electric vehicle, an electric vehicle (electric drive only), a fuel cell vehicle, etc.

[0026] The present invention will be described in more detail below on the basis of exemplary embodiments with reference to the accompanying schematic drawings, which are not to scale. Parts, elements, components, units, elements, and / or patterns having identical, unique, or similar configurations and / or functions are identified by the same reference numerals in the description of the drawings (see below), the description of the symbols, the claims, and in each of the figures of the drawings. Possible alternatives, static and / or kinematic inversions, combinations, etc., not described, not shown, and / or not conclusive in the description of the invention (see above) for the exemplary embodiments of the invention, or its components, patterns, units, structural parts, elements, or parts, can further be gleaned from the description of the symbols and / or the description of the drawings.

In this specification (description (see above for description of the invention, description of the drawings (see below)), symbol descriptions, claims, drawings), implicit features are not explicitly described as features if their absence is not essential to the present invention. In other words, the present invention, which has actually been made and which is not constituted by the prior art, omits said features.

[0028] The features of this specification may be used not only in the manner and / or way specified but also in other ways and / or ways (separation, combination, substitution, addition, uniqueness, omission, etc.).

That is, each feature may be considered as an optional, optional, or preferred feature, i.e., a non-binding feature. Features may thus be isolated from exemplary embodiments, possibly including their surroundings, and then converted into generalized inventive concepts. The absence of a feature in an exemplary embodiment (a latent feature) indicates that the feature is optional with respect to the present invention.

[0032] The present invention will be described in more detail below with reference to three exemplary embodiments (e.g., shown in Figures 5, 7, and 8) of a high current and / or high voltage assembly connector 1. The high current and / or high voltage assembly connector 1 is formed as a header 1 (hereinafter simply referred to as assembly connector 1) and includes a shielded contact adapter 20 for the assembly connector 1, for a vehicle assembly 0, and in particular for an electric energy storage device 0 for an electric vehicle.

[0033] The present invention can be generally used in the electrical field for electrical assemblies, with one exception being terrestrial power engineering and the like. Furthermore, the present invention will be described and illustrated in greater detail using preferred exemplary embodiments, but the present invention is not limited to the disclosed exemplary embodiments, which are of a more fundamental nature. Other variations can be derived from the exemplary embodiments and / or the above (description of the invention) without departing from the scope of protection of the present invention.

[0034] The drawings show only the physical parts of the subject matter of the present invention necessary for understanding the present invention. The names connector and mating connector, contact means and mating contact means, etc., should be construed synonymously, i.e., are interchangeable in some cases. Below, the description of the present invention with reference to the drawings refers to the axial direction Ax, the radial direction Ra, and the circumferential direction Um of the connector assembly 1 and its shield contact adapter 20.

[0035] Vehicle floor panels (see Assembly Wall 5 below) are protected from stone impact by a coating, often a CDC coating, which makes electrical shield contact in the floor panel quite difficult for electrical connectors (see Assembly Connector 1 below) located in the floor panel. To solve this problem, masking of the sub-floor panels can be used for the coating. However, such masking is expensive and can cause corrosion problems for the sub-floor panels.

[0036] Additionally, depending on the assembly 0, connectors without such protection may, of course, allow water to enter the electrical connection system with which the connector is associated, thus requiring additional seals to protect against pooled water. Furthermore, CDC sheet metal screws can generate metal dust during connector installation / removal, which can cause significant problems for electrical connectors. In accordance with the present invention, these problems are solved using the shield contact adapter 20 of the connector assembly 1.

[0037] 1 and 2 show an assembly connector 1 mounted to an assembly wall 5. Here, the assembly connector 1 is mounted both inside (see FIG. 1) and outside (see FIGS. 1 and 2) the assembly 0, and the assembly connector 1 extends through a connector through-opening 50 in the assembly wall 5. That is, on the one hand, a portion 30 of the assembly connector 1 inside the assembly is arranged on the inside 51 of the assembly wall 5 inside the assembly 0, and on the other hand, a portion 10 of the assembly connector 1 outside the assembly is arranged on the outside 52 of the assembly wall 5 outside the assembly 0.

[0038] The assembly connector 1 in this case leads inward from the outside into the assembly 0 or vice versa. Naturally, other configurations, for example completely inside the assembly, are likewise possible. Only the assembly connector 1 can or is attached to the assembly wall 5. The assembly connector 1 (see also Figures 3, 5 and 6) comprises a housing 120 or outer housing 120 substantially in the part 10 outside the assembly, and contact means receptacles 140 of the housing or outer housing can be arranged according to the several electrical contact means 40 of the assembly connector 1. Here, the contact means receptacles 140 of the individual assembly connectors 1 can be formed together in one piece, in particular integrally, or can be formed in several pieces.

[0039] In the mounted state of the assembly connector 1 (see especially FIG. 2 ), the contact means 40 are placed, possibly sealed, in the corresponding contact means receptacle 140, and the contact means are fixed by or clamped to the contact means receptacle 140. The contact means receptacle 140 is automatically placed, possibly sealed, in the housing 120 or outer housing 120, and is fixed by or clamped to the housing 120 or outer housing 120.

[0040] A connector shield 100 (see also FIG. 4 ), formed substantially in one piece or integrally outside the radial direction Ra, is provided in the contact means receptacle 140, and the connector shield extends from a part 10 of the assembly connector 1 outside the assembly through the connector through opening 50 to a part 30 of the assembly connector 1 inside the assembly, or vice versa. At the part 10 outside the assembly, shields of electrical conductors (cables, bus bars, etc.) can be brought into electrical contact with the connector shield 100, where the electrical conductors can be connected to the assembly connector 1. For this purpose, the connector shield 100 can include electrical contact lugs, in particular spring contact lugs.

[0041] In this case, the connector shield 100 comprises a shielding contact sleeve for each contact means 40, which extends completely circumferentially around the contact means 40. In this case, the shape of the shielding contact sleeve is adapted to the shape of the contact means 40. The illustrated connector shield 100 comprises two such shielding contact sleeves arranged substantially parallel to one another, which are preferably integrally connected to one another via a web. The web may be formed (through openings) in such a way that the connector shield 100 can be fixed or fastened to the assembly connector 1.

[0042] Inside the assembly 0, the electrical shield terminates, or the electrical shield of the assembly connector 1 requires an electrical connection with the assembly wall 5, which may be coated so as to be electrically insulating. Here, at the inner part 30 of the assembly, the shield contact adapter 20 is in direct electrical contact with the connector shield 100 (see also in particular Figures 7 and 8), which is naturally in direct or indirect electrical contact with the conductive layer of the assembly wall 5.

[0043] Direct electrical contact between the connector shield 100 and the shield contact adapter 20 is effected by electrical contact lugs 102 of the connector shield 100, which are formed in particular as spring contact lugs 102. Naturally, alternatively or additionally, contact lugs or spring contact lugs can likewise be provided on the shield contact adapter 20 (not shown). In this case, the connector shield 100 and the shield contact adapter 20 are formed and arranged in the assembly connector 1 such that the contact lugs 102 of the connector shield 100 are in electrical contact with the shield contact adapter 20 radially inside Ra of the shield contact adapter 20 (see Figures 2, 5 and 6).

[0044] For direct electrical contact between the shield contact adapter 20 and the assembly wall 5, the shield contact adapter 20 may include a coating cutting device (not shown) that can cut open the coating of the assembly wall 5, so that the shield contact adapter 20 can make electrical contact with the conductive layer of the assembly wall 5 (axial pressing area, see above).

[0045] Alternatively or additionally, an indirect electrical contact between the shield contact adapter 20 and the assembly wall 5 or its conductive layer can be formed via at least one fastening means 22 (see Figures 5 and 6) of the shield contact adapter 20 (hollow cylindrical contact, see above). Here, the shield contact adapter 20 is fastened to the assembly wall 5 by the fastening means 22. Such fastening means 22 can be formed, for example, as a rivet, in particular an SPR rivet, a screw, etc.

[0046] Further, alternatively or additionally, indirect electrical contact between the shield contact adapter 20 and the assembly wall 5 can be made via the housing 120 or the mounting bushing 122 of the outer housing 120. That is, the shield contact adapter 20 is in electrical contact with the fastening means 22, the fastening means 22 is in electrical contact with the mounting bushing 122, and the mounting bushing 122 is in electrical contact with the assembly wall 5.

[0047] The illustrated shield contact adapter 20 (see especially Figures 7 and 8) comprises at least one plate-like base 200, by means of which the shield contact adapter 20 can be fastened to the assembly wall 5 by means of fastening means 22 (see especially Figures 5 and 6). Furthermore, the shield contact adapter 20 comprises a connection through-opening 250 in which a portion 30 of the assembly connector 1 inside the assembly can be provided or in which a portion 30 is provided. This represents a basic embodiment of the shield contact adapter 20 (see Figure 8 without the centering ring 210).

[0048] In the mounted state of the assembly connector 1 on the assembly wall 5, the spring contact lugs 102 of the connector shield 100 contact the shield contact adapter 20 in the radial direction Ra inside the shield contact adapter 20, i.e. inside the connection through-opening 250. In this case, the spring contact lugs 102 of the connector shield 100 are deflected in the radial direction Ra. Here, the contact area extends almost completely along the inside of the connection through-opening 250 in the circumferential direction Um, so that an electrical peripheral contact is formed.

[0049] To easily mount the shield contact adapter 20 in / on the connector through-opening 50 in the assembly wall 5, the shield contact adapter 20 may include a centering ring 210 or a functionally identical device that can be at least partially form-fitted into the connector through-opening 50. In this case, the centering ring 210 or the functionally identical device preferably protrudes somewhat from the plate-shaped base 200 in the axial direction Ax and extends completely around the plate-shaped base 200 in the circumferential direction Um. Inside the radial direction Ra, the centering ring 210 or the functionally identical device also defines the connection through-opening 250.

[0050] Furthermore, the shielding contact adapter 20 can include a peripheral wall 220, which, if the centering ring 210 is present, is arranged on the side of the plate-shaped base 200 opposite the centering ring 210. This apron prevents water or other liquids present on the assembly wall 5 from entering radially inwardly into the shielding contact adapter 20 and from the shielding contact adapter 20 to the assembly connector 1 in the event of a liquid-tight connection between the assembly wall 5 and the shielding contact adapter 20. In this case, the peripheral wall 220 protrudes from the plate-shaped base 200 in the axial direction Ax and extends completely around the plate-shaped base 200 in the circumferential direction Um. Inside the radial direction Ra, the peripheral wall 220 also defines a connection through-opening 250.

[0051] When both the centering ring 210 and the peripheral wall 220 are arranged on opposite large-area sides of the plate-like base 200, the centering ring 210 and the peripheral wall 220 may or may not be coplanar in the axial direction Ax. If appropriate, the peripheral wall 220 may have a somewhat larger or smaller outer circumference than the centering ring 210. Here, the shield contact adapter 20 is formed as a three-dimensional structural part in the shape of a closed apron (see FIG. 7) or a closed ring (see FIG. 8).

[0052] The shield contact adapter 20 can be formed for a single assembly connector 1 or for multiple assembly connectors 1, for example two assembly connectors 1. In a second case, the shield contact adapters 20 for multiple assembly connectors 1 can be combined to form a combined shield contact adapter plate (not shown). That is, these shield contact adapters 20 share a single plate-shaped base 200, which includes a corresponding number of connection through-openings 250 and, possibly, a corresponding number of centering rings 210 and / or peripheral walls 220. Here, only a single centering ring 210 can be provided.

[0053] The incorporation of the shield contact adapter 20 into the connector assembly 1 creates an electrically accessible surface in the radial direction Ra for the connector shield 100 or its contact lugs 102. Here, the connector shield 100 can remain the same; that is, the connector shield 100, which previously electrically contacted the assembly wall, now contacts the shield contact adapter 20. The shield contact adapter 20 can be a component made of die-cast aluminum. Additionally, the shield contact adapter 20 can be configured as a protection against water, especially standing water, for example in the event of a leak. The mechanical and, if necessary, electrical connection between the shield contact adapter 20 and the assembly wall 5 can be realized using technologies already used by the user.
