ELECTRICAL TRANSFER POINT FOR MOTOR VEHICLES

Description

[0001] The subject matter relates to an electrical transfer point, in particular for motor vehicles.

[0002] With the electrification of automobiles, power outputs of several hundred kW are now occasionally transmitted via the vehicle's electrical system. With such enormous power peaks, the long-term, reliable conduction of current and the heat generated by ohmic losses is becoming increasingly challenging. Against this backdrop, the demands on conductive components, particularly cables, connectors, connecting elements, and transfer points, have increased dramatically compared to previous 12V electrical systems.

[0003] One of the greatest challenges in the electrification of automobiles lies in minimizing the charging times of the energy storage systems involved. The tank of a conventional vehicle with a combustion engine can be filled with fuel within a few minutes, containing enough energy for hundreds of kilometers of driving. The situation is different, however, for electric vehicles, which typically require a high-capacity electric battery to be charged at a charging station. High currents and voltages are used to charge the battery as quickly as possible, ideally significantly faster than it is subsequently discharged during driving.

[0004] To transfer the necessary high charging power from the charging station to the vehicle's battery, the entire transmission path from the charging station socket via the vehicle's socket to the battery must have excellent electrical conductivity. In particular, all transitions between the individual components of the transmission path must exhibit particularly low contact resistance.

[0005] Conductive components must exhibit high electrical and thermal conductivities, as well as high heat capacities. They must also be capable of dissipating large amounts of heat into the environment. Localized heating due to increased electrical and / or thermal resistance and / or low heat capacity can have fatal consequences for vehicle safety. The resulting high temperatures can trigger fires and / or explosions.

[0006] A particularly sensitive area of ​​vehicle electrical systems is, of course, the energy storage device involved and its immediate electrical environment. The terminals of an energy storage device, usually an electric accumulator, are often permanently connected to a transfer point. The transfer point can, in particular, establish the connection between the energy storage device and the rest of the vehicle's electrical system and / or a charging socket. The entire power consumed in the vehicle flows through the energy storage device's terminals during battery operation. The same applies to the transfer point.

[0007] Often, particularly for reasons of compact cabling, it is desired that the transfer point allow a change in the orientation of the contacts in relation to the connections of the energy storage device. The at least two connections of the energy storage device can, for example, be spaced from one another in a first direction. The connections of the transfer point can be spaced from one another in a direction different from the first direction. This results in difficulties for the electrical properties of the transfer point, particularly since the current paths of the various connections have different geometric properties, in particular a different length. It would be desirable to align the current paths of the respective connections and avoid imbalances in conductivity or other electrical and thermal properties.In particular, the high requirements regarding the electrical and thermal properties of the transfer point must be ensured to the required extent.

[0008] Finally, given the consistently high voltages between the energy storage device's terminals, it is important that it remains absolutely dry and / or protected from other environmental influences such as oxidizing gases. The energy storage device is preferably sealed from the vehicle's surroundings and also from the vehicle interior. The transfer point can, in particular, connect the energy storage device to the vehicle interior. This must be designed in such a way that the sealing of the energy storage device remains unaffected by environmental influences. The transfer point can therefore also serve as a feedthrough.

[0009] US 2018 / 268959 discloses an electrical transfer point for motor vehicles with two connecting flat parts made of a metallic material, wherein the connecting flat parts partially extend in a common conductor plane. The connecting flat parts have a first and a second connecting section, the first connecting sections being arranged along a common first straight line extending in the conductor plane, and the second connecting sections being arranged along a common second straight line extending in the conductor plane.

[0010] The object was therefore to provide a transfer point that could withstand the high electrical and thermal loads that act on it in direct connection with the energy storage of today's electric vehicles.

[0011] The problem is solved by a transfer point according to claim 1.

[0012] The transfer point in question initially comprises at least two connecting flat parts.

[0013] A connecting flat part can have two broad sides arranged opposite one another. The broad sides can, for example, be aligned essentially parallel to one another. The two broad sides can have essentially the same shape. Deviations between the shapes of the broad sides are also possible. For example, one of the broad sides can have a smaller surface area than the other broad side of the connecting flat part.

[0014] For the connecting flat part, a thickness can be defined as the dimension of the connecting flat part perpendicular to at least one broad side of the connecting flat part. The thickness of the connecting part can be essentially constant across at least one of the broad sides of the connecting part. The seal can also vary across the broad side of the connecting flat part.

[0015] In addition, the connecting flat part includes narrow sides. The narrow sides can surround the wide sides all the way around. The narrow sides can be divided into individual narrow sides. A single, circumferential narrow side can also be defined. At least one of the narrow sides can be aligned essentially perpendicular to at least one wide side of the connecting flat part.

[0016] A substantially perpendicular alignment of two surfaces can be understood in such a way that the two surface normals to the two surfaces are substantially perpendicular to each other.

[0017] Furthermore, to describe the geometric nature of the transfer point in question, it is useful to define a conductor plane. The conductor plane is not to be understood in the strict mathematical sense as a plane with a purely two-dimensional extension. The conductor plane can have an extension in all three spatial directions. In particular, the conductor plane can extend essentially indefinitely in two mutually perpendicular width directions. In a thickness direction of the conductor plane perpendicular to the width directions, the conductor plane can have a limited extension. This can be defined as the thickness of the conductor plane. The thickness direction can also be referred to below as the surface normal of the conductor plane.

[0018] At least one, preferably at least two, connecting flat parts extend into the conductor plane. The conductor plane can, for example, have substantially the same thickness as at least one of the connecting flat parts. The conductor plane can also be thicker or thinner than at least one of the connecting flat parts.

[0019] The at least two connecting flat parts can have substantially the same thickness. The at least two connecting flat parts can also have at least partially different, i.e., different, thicknesses from one another.

[0020] In one embodiment, the at least two connecting flat parts are aligned so that their surfaces are parallel to one another. This can mean, in particular, that the broad sides of the at least two connecting parts are aligned substantially parallel to one another. At least one of the and / or the at least two connecting flat parts can be aligned parallel to the conductor plane. At least one of the connecting flat parts can also run at an angle to the conductor plane. This can mean that at least one of the broad sides of the connecting flat part has a different orientation than the conductor plane. For example, there can be an angle of 5 to 10 degrees between the surface normal to the broad side of the connecting part and the surface normal to the conductor plane.Even if one of the connecting flats is defined as being parallel to the conductor plane, a small angle, for example from 0.1 to 5 degrees, may exist between the surface normal on the broad side of the connecting flat and the surface normal of the conductor plane.

[0021] The at least two connecting flats do not touch each other. The at least two connecting flats are spaced apart from each other, in particular with a gap. In particular, the at least two connecting flats are electrically insulated from each other. The broad sides of the at least two connecting flats are arranged substantially without overlapping each other. In particular, in a plan view of at least one broad side of at least one of the at least two connecting flats, it is evident that the at least two connecting flats do not overlap each other.When it is stated below that the at least two connecting flat parts do not overlap one another and / or are non-overlapping, this means that the two connecting flat parts are non-overlapping in the direction of the surface normal to the conductor plane and / or in the direction of the surface normal on at least part of a wide side of at least one of the at least two connecting flat parts. The at least two connecting flat parts can overlap one another in the direction of the surface normal on at least part of the narrow sides. This is due to the fact that the at least two connecting flat parts lie in one plane, in particular in the conductor plane.

[0022] At least one, preferably the at least two connecting flat parts each have a first and a second connecting section. For example, the connecting sections can be arranged at a respective distal end of the respective connecting flat part. A connecting section can be suitable for connecting an electrically conductive element thereto. A connecting section has a spatial extension on the broad side of the connecting flat part. The connecting section can border an edge of the broad side. A connecting section can also be circumferentially surrounded by different regions of the broad side.

[0023] For example, the connecting flat part can be divided into at least two connecting sections and a separate conductive section. The conductive section can be electrically arranged between the two connecting sections. The conductive section can also comprise at least one of the connecting sections or the at least two connecting sections.

[0024] A first and a second connecting section can be defined for each connecting flat part. The first and second connecting sections of a given connecting flat part are, in particular, non-overlapping.

[0025] The first connecting sections of the at least two connecting flat parts are arranged along a common first straight line. For example, the first connecting sections are spaced apart along the common first straight line. The common first straight line extends in the conductor plane. The common first straight line can in particular be arranged parallel to at least one of the broad sides of at least one of the connecting flat parts. Additionally or alternatively, the first common straight line can be arranged parallel to the conductor plane. The first common straight line passes in particular through both the first connecting section of a first of the at least two connecting flat parts and through the first connecting section of a second of the at least two connecting flat parts. For example, the first straight line can run through the center of at least the first connecting section of a first and / or the at least two connecting flat parts.The center can be defined here, for example, as the geometric center of gravity of the area of ​​the first connecting section.

[0026] The second connecting sections of the at least two connecting flat parts are arranged along a common second straight line. For example, the second connecting sections are spaced apart along the common second straight line. The common second straight line extends in the conductor plane. The common second straight line can in particular be arranged parallel to at least one of the broad sides of at least one of the connecting flat parts. Additionally or alternatively, the common second straight line can be arranged parallel to the conductor plane. The second common straight line runs in particular through both the second connecting section of a first of the at least two connecting flat parts and the second connecting section of a second of the at least two connecting flat parts. For example, the second straight line can run through the center of at least the second connecting section of a first and / or the at least two connecting flat parts.The center can be defined here, for example, as the geometric center of gravity of the surface of the second connecting section.

[0027] The first connecting sections of the at least two connecting flat parts can be arranged on a common side of the second straight line. For example, the conductor level can be divided into two separate regions by the second straight line. The at least two first connecting sections of the at least two connecting flat parts can be located in one of these two regions, the first section region. At least one of the connecting sections and / or the at least two connecting sections can be located entirely in the first section region. In this case, the second straight line does not run through any of the first connecting sections. At least one of the at least two connecting sections can also be arranged only partially in the first section region, in particular so that the second straight line runs through it. The at least two first connecting sections are each arranged at least partially in the first section region.In particular, at least the respective center of the at least two first connecting sections is arranged in the first section region. The center can be defined here, as described above, for example, as the geometric center of gravity of the respective first connecting section.

[0028] The second connecting sections are arranged on opposite sides of the first straight line, in particular in the conductor plane. The at least two second connecting sections can each be arranged entirely on one of the two sides of the first straight line. In particular, the at least two second connecting sections can be free from crossing by the first straight line. It is also possible for at least one or at least two of the second connecting sections to be crossed by the first straight line. The at least two second connecting sections are each arranged at least partially on opposite regions of the first straight line. In particular, at least the respective centers of the at least two second connecting sections are arranged on opposite sides of the first straight line.The center of a second connection section can be defined here, as described above, for example, as the geometric center of gravity of the respective second connection section.

[0029] In one embodiment, the at least two connecting flat parts extend in a longitudinal direction. In particular, a first connecting flat part can extend in a first longitudinal direction. In particular, a second connecting flat part can extend in a second longitudinal direction, wherein the first longitudinal direction can in particular substantially correspond to the second longitudinal direction. The first and second longitudinal directions can also differ from one another in their respective orientation.

[0030] A longitudinal direction of a connecting flat part can, for example, lead from the first connecting section of the connecting flat part to the second connecting section of the connecting flat part. A longitudinal axis of a connecting flat part can also be defined as the direction in which the connecting flat part has the greatest spatial extent. A common longitudinal direction can be defined for the at least two connecting flat parts. The common longitudinal direction of the at least two connecting flat parts can deviate from the respective longitudinal directions of the connecting flat parts. The longitudinal directions of the connecting flat parts can also substantially coincide with the common longitudinal direction of the connecting flat parts.

[0031] In one embodiment, the at least two connecting flat parts can extend from a common first distal end to a common second distal end. The respective distal end can in particular be a distal end of the transfer support point.

[0032] The first and / or second distal end of the transfer support point can be a point on, for example, one of the at least two connecting flat parts. It is also possible to define the first and / or second distal end as a spatially extended area. In particular, the first and second distal ends of the transfer support point do not overlap each other.

[0033] For example, at least one first connecting section or the at least two first connecting sections of the transfer support point can be arranged substantially at the first distal end. They can also be arranged only partially at the first distal end. The end point of at least one of the at least two connecting flat parts can be located in the first distal end of the transfer support point. The end point of a connecting flat part can be defined, for example, as the point on the connecting flat part that marks the end of the connecting flat part along the longitudinal axis of the connecting flat part and / or along the common longitudinal direction of the transfer support point.

[0034] For example, at least one second connecting section and / or the at least two second connecting sections of the transfer support point can be arranged substantially at the second distal end. At least one of the at least two second connecting sections and / or the at least two second connecting sections can be arranged substantially entirely at the second distal end. It is also possible for at least one and / or the at least two second connecting sections to be arranged partially outside the second distal end.

[0035] The above-described arrangement of the first and second connecting sections of the at least two connecting flat parts enables various orientations of the connecting sections. For example, the first connecting sections can be arranged in a first orientation and the second connecting sections in a second, different orientation, for example, one substantially perpendicular to the first. Changing the orientation of the connecting sections from the first to the second connecting sections enables compact contacting of an energy storage device. Typically, the terminals of an energy storage device are spaced apart in a first orientation. The first orientation is often parallel to the edge of the energy storage device.If two parallel, adjacent power lines are contacted at the terminals of the energy storage device, they necessarily initially run perpendicular to the edge of the energy storage device. In an automobile, it is often desired, particularly to save space, for a line to run parallel to the edge of the energy storage device. The change of direction enabled by the transfer point is helpful in this regard. However, the challenge is that two different paths arise at the transfer point for the at least two connections. These include, on the one hand, a path for the connection between the first and second connecting sections of a first connecting flat part and, on the other hand, a path between the first and second connecting sections of a second connecting flat part.In particular, a first of the at least two first connecting sections of the at least two connecting flat parts is further away from the second connecting sections of the at least two connecting flat parts than at least a second of the at least two first connecting sections. In particular, these mutually different paths arise because the at least two connecting flat parts are arranged with essentially no overlap with one another.

[0036] It is desirable to align the electrical properties of the at least two current-carrying paths. If the at least two current-carrying paths have similar electrical properties, at least approximate symmetry is achieved between the at least two current-carrying paths. In this way, it can be achieved that none of the at least two current-carrying paths is exposed to increased heating, in particular due to ohmic losses.

[0037] Apparently, however, the proposed arrangement of at least two connecting flats arranged without overlap in a common conductor plane with connecting sections oriented at an angle relative to each other results in one of the current-carrying paths being significantly longer than the other. It would seem more logical to arrange the at least two connecting flats one above the other so that their respective broad sides overlap.

[0038] It was recognized that an interlocking of at least two connecting flat parts can minimize the differences in the path lengths of the current-carrying paths.

[0039] In one exemplary embodiment, at least a first of the at least two connecting flat parts has a recess. The recess is located, in particular, in an area close to the first connecting section of the connecting flat part. A recess in a connecting flat part is, in this case, a recess in the narrow side. The recess extends, in particular, across the entire thickness of the connecting flat part. Thus, in a plan view of the broad side of the connecting flat part, in particular in a plan view in the direction of the surface normal to the broad side of the connecting flat part, the recess appears as a narrowing of the broad side cut into the broad side.

[0040] To simplify the following description, a short and a long connecting flat part are first defined. The first connecting section of the short connecting flat part is located closer to the second connecting sections of the at least two connecting flat parts than the first connecting section of the long connecting flat part.

[0041] In particular, the long connecting flat part has a recess.

[0042] The recess of the long connecting flat part can be arranged in a narrow edge of the long connecting flat part, which faces the short connecting flat part. A narrow side facing another connecting flat part in this way can be referred to as the inner narrow side.

[0043] A portion of the short connecting flat engages the recess of the long connecting flat. This may mean, for example, that the short connecting flat extends at least partially into the convex envelope of the wide side of the long connecting flat, particularly in the area of ​​the recess.

[0044] In particular, the first connecting section of the short connecting flat part can at least partially engage in the recess of the long connecting flat part.

[0045] The width of the long connecting flat part can be reduced in the region of the recess in the long connecting flat part. The width can, for example, be measured essentially perpendicular to the longitudinal direction of the connecting flat part and / or the longitudinal direction of the transfer support point. In particular, it is possible for the width of the long connecting flat part in the region of the recess not to be reduced compared to other, different regions of the long connecting flat part. This can be achieved, for example, by directing the narrow edge of the long connecting flat part away from the recess on the side of the long connecting flat part opposite the recess.In one exemplary embodiment, the two narrow sides of the long connecting flat part, which run essentially along the longitudinal direction of the connecting flat part and are opposite one another, can be guided essentially parallel to one another, whereby deviations from a parallel course are permitted in some areas. This makes it possible to ensure that the width of the long connecting flat part remains essentially constant along the longitudinal direction.

[0046] The long connecting flat part can, for example, initially run in a substantially straight line along the longitudinal direction of the transfer support point, starting from the second connecting section. In the region of the first connecting section of the short connecting flat part, the course of the long connecting flat part can change from a substantially straight course to an at least partially curved course, with the curved region at least partially extending around the first connecting section of the short connecting flat part.

[0047] The short connecting flat part can, for example, have a shape similar to that of an L. The short connecting flat part can, for example, have a substantially straight guide section between the first and the second connecting section of the short connecting flat part. The guide section of the short connecting flat part can extend substantially straight from the second connecting section in the direction of the first connecting section of the first connecting flat part. The first connecting region of the short connecting flat part can be arranged at the end of the guide section facing away from the second connecting section. The first connecting part of the short connecting flat part can, in particular, extend in the direction of the long connecting flat part.In the present transfer point, the first connecting section of the short connecting flat part can therefore be offset in the direction of the long connecting flat part, for example, substantially parallel to the second straight line and / or substantially perpendicular to the first straight line. In this way, for example, it can be achieved that the first connecting section of the short connecting flat part, in particular its center point, is arranged at least partially and / or preferably completely between the second connecting sections of the short and long connecting flat parts in projection parallel to the conductor plane and perpendicular to the second straight line.In order to select the position of the first connecting section of the short connecting flat part as described (offset in the direction of the long connecting flat part), the recess in the long connecting flat part allows the first connecting section of the short connecting flat part to engage there in the long connecting flat part.

[0048] The first connecting section of the long connecting flat part, in particular its center point, can also, like the first section of the short connecting flat part, lie at least partially between the second connecting sections of the short and long connecting flat parts in a projection parallel to the conductor plane perpendicular to the second straight line. For this purpose, the first connecting section of the long connecting flat part is guided in the direction of the short connecting flat part on the side of the long connecting flat part facing away from the second connecting sections of the long and short connecting flat parts.

[0049] In the region of the guide section of the short connecting flat part, the long connecting flat part can comprise a guide section running essentially parallel thereto.

[0050] Two of the at least two connecting flat parts have inner narrow sides that face the other connecting flat parts. A gap is arranged between the inner narrow sides of the at least two connecting flat parts. The gap can have a minimum width along the inner narrow sides. For example, a minimum width of at least 1 mm to 1 cm or a higher minimum width can be provided between the at least two connecting flat parts.

[0051] Two of the at least two connecting flat parts can also have a substantially constant distance from each other along the inner narrow sides. Deviations from a constant distance are permitted in some areas.

[0052] In one embodiment, the first straight line is oriented substantially perpendicular to the second straight line. For example, the first straight line and the second straight line may enclose an angle of 90° + / - 1° to + / - 10°.

[0053] In one embodiment, the first straight line and the second straight line intersect at the conductor level. Intersecting two straight lines can, in particular, mean that they meet at a common intersection point. Intersecting two straight lines can also mean that two straight lines are as close as possible to each other at a particular point on the respective straight line. For example, the shortest distance between the two straight lines can be determined, and the midpoint of this distance can be defined as the intersection point of the straight lines, in particular without the two straight lines meeting.

[0054] In particular, the two straight lines can meet at an intersection point which is arranged between the second connecting sections of the at least two connecting flat parts.

[0055] In one embodiment, the second connecting sections of the at least two connecting flat parts can be equidistant from the first straight line. This can mean that the respective distances between the second connecting sections and the first straight line are substantially equal. The distance between a second connecting section and the first straight line can, for example, be measured starting from the point on the second connecting section that is closest to the first straight line. The distances between a second connecting section and the first straight line can also be measured, for example, starting from the center point of the second connecting section to the first straight line. The center point is determined here, for example, as the geometric center of gravity of the second connecting section.

[0056] In one embodiment, the distance between the second connecting sections on two of the at least two connecting flat parts is substantially equal to the distance between the first connecting sections of the connecting flat parts.

[0057] At least one of the connecting flats can be formed from a metal material. In particular, a connecting flat can be formed from aluminum, copper, e-copper, and / or combinations thereof. Alloys of the aforementioned materials and / or other metal materials are also possible.

[0058] For example, the at least two connecting flat parts can be formed from E-copper.

[0059] In one embodiment, at least one of the connecting flats is coated. In particular, at least one of the connecting flats can be coated with a metal material. For example, the connecting flat can be coated with silver, gold, nickel, combinations thereof, and / or with multiple layers, in particular of the aforementioned materials, in particular with pre-nickel-plated silver.

[0060] At least one or at least two connecting flats can be forged. At least one of the connecting flats can also be stamped, cut out, cast, and / or injection-molded. A forged connecting flat has the particular advantage that its shape can be freely designed and that the material is highly strong. Furthermore, particularly thick and thus highly conductive – both thermally and electrically – connecting flats can be produced, as well as connecting flats with a high heat capacity.

[0061] In one exemplary embodiment, a connecting bolt can be arranged on at least one of the at least two connecting parts. The connecting bolt extends, in particular, in an extension direction beyond at least one broad side of the connecting flat part. The extension direction of the connecting bolt can, in particular, run substantially perpendicular to the broad side of the connecting flat part.

[0062] The connecting bolt can, in particular, have a hole. The hole in the connecting bolt can, for example, be designed as a blind hole or a through hole. For example, a thread can be arranged in the hole. In particular, a blind hole in the connecting bolt can have a thread. The hole in the connecting bolt can, for example, run at least partially through the connecting bolt perpendicular to the direction of extension of the connecting bolt. It is also possible for the hole to run essentially parallel to the direction of extension of the connecting bolt.

[0063] A connecting bolt can be arranged, in particular, in a connecting section of at least one of the and / or at least two connecting flat parts. The connecting bolt is preferably arranged in the first connecting section of the connecting flat part.

[0064] In one embodiment, the transfer point in question is connected to an energy storage device via the second connecting section. Accordingly, the first connecting sections, and in particular the connecting bolts arranged therein, serve to contact additional lines that are connected, for example, to the vehicle's electrical system. For example, lines can be screwed into the threads of the connecting bolts using screws. Lines can also be welded and / or clamped and / or plugged, riveted, or otherwise connected to the connecting bolts.

[0065] In one embodiment, an opening is arranged in at least one of the at least two connecting flat parts. The opening extends, in particular, across the entire thickness of the connecting flat part. For example, the opening can be formed as a through hole. It is also possible for a blind hole to be arranged in the connecting flat part. The opening of the connecting flat part can, for example, have a thread.

[0066] In one embodiment, an opening is arranged in at least one of the and / or in the at least two connecting flat parts in the second connecting section.

[0067] It is also possible for openings to be arranged in both the second and first regions of the at least two connecting flat parts. In an alternative embodiment, connecting bolts can also be arranged in the second and first connecting sections of the at least two connecting flat parts. In a preferred embodiment, at least one opening is arranged in each of the first connecting sections of the at least two connecting flat parts, and at least one connecting bolt is arranged in each of the first connecting sections.

[0068] In one embodiment, the at least two connecting flat parts are at least partially surrounded by a common housing.

[0069] The housing is preferably formed from a non-conductive material, for example from a plastic, in particular from a high-temperature plastic, for example PA6GF15, UL94 or another high-temperature plastic, and / or from another non-conductive material such as ceramic, glass, silicone, insulating coated metal and / or other materials.

[0070] In an advantageous embodiment, the at least two connecting flat parts are at least partially overmolded by a common housing. This allows for a particularly good connection between the housing and the surface of the connecting flat parts. In particular, this prevents liquid or other unwanted substances from spreading along the connecting flat parts, starting from the first connecting sections to the second connecting sections and / or vice versa.

[0071] The housing preferably lies directly against the connecting flat parts, at least in some areas. In particular, the housing encloses the at least two connecting flat parts in the region of the guide sections. In particular, the housing is arranged at least partially between the at least two connecting flat parts. In particular, the housing can be arranged at least partially between the inner narrow sides of the at least two connecting flat parts.

[0072] The housing fulfills, among other things, the function of isolating the connecting flats from one another. Another function of the housing is to protect the first connecting sections and the second connecting sections of the at least two connecting flats from one another. In particular, the housing prevents moisture located in the area of ​​the first connecting sections from moving to the second connecting sections and vice versa. In particular, a housing that tightly encloses the at least two connecting flats can prevent water from penetrating the connecting flats.

[0073] The housing can, in particular, expose the first connecting sections and / or the second connecting sections. This can mean that no housing layer is arranged in the region of the first connecting sections and / or in the region of the second connecting sections of the at least two connecting flat parts. In this way, it can be ensured that the transfer support point in question can be electrically contacted on both sides, namely in the region of the first connecting sections and in the region of the second connecting sections. The housing can, in particular, completely surround all areas of the at least two connecting flat parts except for the first and second connecting sections.

[0074] A collar can be arranged in the region of the first and / or second connecting sections of at least one of the at least two and / or the at least two connecting flat parts. The collar can surround at least one connecting section and / or more connecting sections, in particular surround them all the way around. A collar around a first connecting section of at least one of the at least two connecting flat parts can, for example, extend essentially perpendicular to the broad side of the connecting flat part. A collar around a second connecting section can, for example, likewise extend at least partially and / or completely all the way around at least one of the and / or more second connecting sections of the at least two connecting flat parts, essentially perpendicular to the broad side of at least one of the connecting flat parts.

[0075] In the region of the first connecting sections, the housing can have a collar. The collar can extend in particular in the direction of extension of at least one of the connecting bolts. The collar can surround the connecting bolts essentially all the way around. The collar can project beyond the connecting bolts of the at least two connecting flat parts in the direction of extension of the connecting bolts. The connecting bolts are thus countersunk in the region encompassed by the collar. This simplifies secure contacting of the connecting bolts. In particular, accidental contacting is prevented. Secondly, the area in which the connecting bolts are located can be better protected against environmental influences.

[0076] In one embodiment, at least one seal can be arranged on the housing.

[0077] A seal can, for example, be formed from a flexible material, particularly plastic, silicone, rubber, cork, or similar materials. In one embodiment, the seal can be manufactured together with the housing using a two-component injection molding process. In this process, two different plastics of different thicknesses are molded together to form a housing. This creates a strong bond between the seal and the housing.

[0078] At least one of the at least one seal can, in particular, have a closed shape. For example, the seal can be in the shape of a rectangle, for example with rounded corners, in the shape of a circle, an ellipse, a polygon, or various other closed shapes.

[0079] At least one of the at least one seals may comprise multiple ribs. A multi-rib seal can improve sealing performance.

[0080] In particular, at least one of the at least one seal can be arranged around the first connecting sections of the at least two connecting flat parts, in particular around the connecting bolts. Alternatively or additionally, a seal can be arranged around the second connecting sections of the at least two connecting flat parts. Because at least one of the at least one seal is arranged around the at least two second and / or the at least two first connecting sections, the transfer support point in question can be tightly connected to the first and / or second connecting sections with a further element. In particular, a gas-tight, liquid-tight, and / or pressure-tight sealing of such a transition to a further component can be enabled.

[0081] In one embodiment, the transfer support point comprises a housing closure. The housing closure can be formed, for example, as a cover. The housing closure can be adapted, for example, to the shape of the housing. The housing closure can be placed on the housing.

[0082] The housing closure can, for example, make contact with the housing in a contact area. For example, the contact area between the housing closure and the housing can be arranged circumferentially around the first connecting sections. In one embodiment, at least one seal is located between the housing closure and the housing. This can, for example, be one of the at least one seals of the housing.

[0083] It is also possible for a seal to be arranged on the housing closure. The seal on the housing closure can also be arranged circumferentially around the first connecting sections when the housing closure rests against the housing. The seal of the housing closure can rest against the housing closure as a separate component. For example, a groove into which a seal can be inserted can be provided on the housing closure. The seal of the housing closure can, for example, be formed from one of the materials listed above for the seal of the housing. The seal of the housing closure can, like the seal of the housing, be manufactured together with the housing closure in a two-component injection molding process.

[0084] The housing closure can be secured to the housing in a captive manner. For example, hinges, straps, rails, or similar retaining means can be provided to secure the housing closure to the housing.

[0085] At least one fastening means can be arranged on the housing. The fastening means can, in particular, be force-fitting and / or form-fitting. For example, the fastening means can comprise a screw receptacle and / or a thread for a screw. A fastening means can also be a hole in the housing. Fasteners can also be, for example, hooks, snap fasteners, rails, clamps, receptacles for one of these fastening means, and / or other fastening means.

[0086] In particular, at least one thread can be embedded in the housing. The thread can be formed from a metal material, for example, as a screw receptacle. The thread can be embedded into the housing wall, for example, overmolded. In particular, multiple threads can be arranged on the housing as fastening means, for example, two, three, four, or more threads.

[0087] The fastening means, in particular threads, can be arranged in the area encompassed by at least one of the at least one seals of the housing.

[0088] Alternatively or additionally, at least one fastening means can be provided on the housing closure. In particular, a hole can be provided on the housing closure, in particular a feedthrough, in particular a feedthrough for a screw, in particular made of a metal material. A feedthrough can in particular be embedded in the housing wall, for example, molded and / or cast therein.

[0089] The housing closure can be held to the housing by means of at least one of the fastening means (of the housing and / or the housing closure). In particular, the housing closure can cover the area of ​​the housing encompassed by one of the at least one seals. In particular, the at least one fastening means can bring about a contact pressure between the housing closure and the housing. In particular, a seal can be arranged in a press fit between the housing and the housing closure. The at least one fastening means can bring about the press fit. In particular, at least one screw can be passed through a hole in the housing cover, screwed into a screw receptacle, in particular a thread on the housing side, and thus bring about a contact pressure.

[0090] In one embodiment, a sealing ring is arranged on at least one of the screws acting as fastening means. The sealing ring can, for example, engage around the screw shaft, in particular circumferentially. The sealing ring can, for example, be arranged in the region of the screw head. The sealing ring can serve as a seal between the screw and the passage of the screw through the housing closure, in particular a gas-tight, liquid-tight, and / or pressure-tight seal.

[0091] In one embodiment, the transfer support point can comprise at least one temperature sensor. The temperature sensor can, for example, be arranged near at least one of the connecting flat parts. For example, the at least one temperature sensor can be arranged near at least one of the at least two first connecting sections. The temperature sensor can, for example, be at substantially the same distance from the at least two connecting flat parts. For example, the at least one temperature sensor can be arranged in an area enclosed by at least one of the at least one seals. In particular, the at least one temperature sensor can be arranged in an area that can be covered by the housing closure. For example, the temperature sensor can be at least partially cast into the housing. For example, the housing has an opening that exposes the receptive area of ​​the temperature sensor.

[0092] In particular, the temperature sensor has at least one connecting cable. The connecting cable of the temperature sensor can be routed out of the housing. In particular, the at least one connecting cable of the temperature sensor can be molded into the housing. The connecting cable of the temperature sensor can be routed out of the housing on a side of the housing facing away from the opening in the housing that exposes the first connecting sections. In particular, the connecting cable of the temperature sensor can be routed through the housing wall, in particular, molded into the housing wall.

[0093] Since this is a power electronics component, temperature monitoring is of utmost importance for vehicle safety. Because the temperature sensor is located in direct proximity to at least one of the connecting flats, preferably to at least two connecting flats, the temperature of the connecting flat can be measured particularly quickly and precisely.

[0094] In one embodiment, the transfer support point comprises at least one fuse. The fuse can be arranged in the housing. In particular, the fuse can be arranged in a region of the housing encompassed by at least one of the at least one seals. For example, the at least one fuse can be arranged near at least one of the connecting flat parts. In particular, the fuse can be arranged near at least a first connecting section of the transfer support point.

[0095] The transfer point can, in particular, have a fuse that de-energizes at least one of the connecting flat parts as long as the housing closure is not resting on the housing. In particular, this can be an HVIL fuse.

[0096] The at least one fuse can comprise at least one connecting cable. The at least one connecting cable of the at least one fuse can be led out of the housing. In particular, the at least one connecting cable of the fuse can be led through a housing wall. For example, the at least one connecting cable of the fuse can be cast and / or overmolded in a housing wall of the housing. The at least one connecting cable of the at least one fuse can be led out of the housing on a side of the housing that faces away from the opening for the first connecting sections of the transfer support point.

[0097] In one embodiment, a wall is arranged between the housing and the housing closure. The wall can be formed from a conductive material, for example, a metal material and / or other conductive materials. It is also possible to form the wall from an electrically non-conductive material, for example, plastic, glass, ceramic, and / or other non-conductive materials.

[0098] The wall can, for example, have an opening. The first connecting sections of the transfer support point can, for example, be arranged in the opening. For example, the opening can have a round, oval, rectangular, rounded rectangular, triangular, polygonal and / or other shape. The openings can have an area which corresponds at least to the area occupied by a first and / or the at least two first connecting sections. In particular, the at least two connecting bolts can be accommodated in the opening in the wall. For example, at least one safety device can additionally be passed through the opening. In particular, the opening in the wall is smaller than the area enclosed by the seal of the housing and / or the seal of the housing closure. In particular, the respective seal can completely enclose the opening in the wall.

[0099] For example, the wall can have recesses. Fasteners, for example, can be guided through the recesses. In particular, screws can be guided through the recesses. The recesses can, in particular, be arranged in an area that can be completely enclosed by the seal of the housing and / or the seal of the housing closure, in particular together with the opening in the wall.

[0100] In particular, the at least one fastening means of the housing closure and / or the housing can connect the housing closure to the housing indirectly via the wall. For example, at least one screw can be guided through a passage in the housing cover, through a recess in the wall, and into a screw receptacle in the housing.

[0101] In a preferred configuration, at least the housing closure is in direct contact with the wall in at least a partially circumferential area.

[0102] For example, the housing closure can also be indirectly attached to the wall, in particular via a seal, in particular via a seal of the housing cover.

[0103] On the housing side, the wall can be connected in an area that extends at least partially circumferentially around the at least two first connecting sections. For example, the wall can abut against at least one of the at least one seal of the housing, in particular circumferentially.

[0104] There may be a press fit between the housing closure and the wall. In particular, a seal, in particular a seal of the housing cover, may be arranged in a press fit between the wall and the housing closure.

[0105] Alternatively or additionally, there may be a press fit between the housing and the wall, in particular at least one of the at least one seals of the housing may be arranged in a press fit between the wall and the housing.

[0106] In particular, at least one of the fastening means can hold the housing closure not only to the housing, but in particular to the wall and to the housing. For example, at least one of the fastening means can be inserted from the housing cover through the wall, in particular through a recess in the wall, into a screw receptacle on the housing side, in particular into a thread. By means of the at least one fastening means, a press fit can be produced between at least the housing closure and the wall, in particular by means of a seal. By means of the at least one fastening means, a press fit can be achieved between the housing and the wall, in particular by means of a seal.

[0107] The transition between the housing closure and the wall and / or the transition between the housing and the wall may be at least substantially gas-tight, liquid-tight and / or pressure-tight.

[0108] For example, the wall can form at least part of a safety zone surrounding an energy storage device. In another embodiment, the wall can define the vehicle interior.

[0109] In the following, the subject matter of the invention is explained in more detail with reference to a drawing showing exemplary embodiments. Fig. 1 shows an actual transfer support point according to an embodiment; Figs. 2a-c show actual transfer support points according to embodiments; Fig. 3a shows an actual transfer support point according to an embodiment comprising a housing; Fig. 4 shows an actual housing closure according to an embodiment; Fig. 5 shows an actual transfer support point according to an embodiment comprising a wall; Fig. 6 shows an actual transfer support point according to an embodiment on an energy storage device.

[0110] In Figure 1shows a physical transfer support point 1. This comprises a first connecting flat part 100 and a second connecting flat part 110. The first connecting flat part 100 and the second connecting flat part 110 each comprise a first connecting section 102, 112. The first connecting flat part 100 and the second connecting flat part 110 each additionally comprise a second connecting section 106, 116.

[0111] A connecting bolt 104, 114 can be arranged in the first connecting section 102, 112 of at least one of the connecting flat parts 100, 110. The connecting bolt 104, 114 can have a hole 105, 115. The hole 105, 115 can, in particular, be a blind hole. A thread can be arranged in at least one of the holes 105, 115.

[0112] An opening 108, 118 can be provided in the second connecting section 106, 116 of at least one of the connecting flat parts 100, 110. At least one of the openings 108, 118 can, in particular, be a through-hole 108, 118.

[0113] In addition to the first connecting sections 102, 112 and the second connecting sections 106, 116, a guide section 109, 119 can be defined. The guide section 109, 119 can, for example, connect the first sections 102, 112 with the second sections 106, 116.

[0114] For each of the connecting flat parts 100,110, a broad side 103,113 can be defined. Compared to the Figure 1Located on the visible broad side 103, 113 is another broad side, which can be arranged substantially parallel to the visible, upper broad side 103, 113 and opposite it. The surface orientation of the broad side 103, 113 and / or the surface orientation of the opposite broad sides can be substantially constant for a respective connecting flat part 100, 110. The surface orientations of all four broad sides 103, 113, etc. of the two connecting flat parts 100, 110 shown can also be substantially the same.

[0115] The at least two connecting flat parts 100,110 can be located in a common conductor level.

[0116] In particular, the broad sides 103, 113 of the at least two connecting flat parts 100, 110 do not overlap each other, they are non-overlapping. This can mean that in the plan view of the at least two connecting flat parts 100, 110 in the direction of the surface normal to at least one broad side 103, 113 of the at least two flat parts 100, 110 as in Figure 1 shown that they are free of overlap, ie they are at odds with each other.

[0117] In the embodiment shown, it can be seen that a gap exists between the two connecting flat parts 100, 110. In particular, the gap and / or the distance between the at least two connecting flat parts 100, 110 is substantially constant along the at least two connecting flat parts 100, 110.

[0118] Narrow sides 107, 117 can also be defined for the two connecting flat parts 100, 110. The narrow sides can, for example, be arranged substantially perpendicular to the at least two wide sides 103, 113. More precisely, outer narrow sides 107a, 117a can be defined. In addition, inner narrow sides 107b, 117b can be defined, which face the respective other connecting flat part 100, 110.

[0119] The connecting flat parts 100, 110 can be divided into a long connecting flat part 100 and a short connecting flat part 110. The first connecting region 112 of the short connecting flat part 110 has a smaller distance from the second connecting sections 106, 116 than the connecting section 102 of the long connecting flat part 100.

[0120] One of the connecting flat parts 100, 110, in particular the long connecting flat part 100, has a recess 101. The recess 101 of the long connecting flat part 100 is arranged in particular in the guide section 109. It can be seen that the width of the connecting flat part 100 remains essentially unchanged by the recess 101. This is achieved by guiding both the inner narrow side 107b and the outer narrow side 107a away from the short connecting flat part 110 in the region of the recess 101.

[0121] A first straight line 121 can be laid through the first connecting sections 102, 112. The first straight line 121 runs, in particular, substantially through the center of at least one of the first connecting sections 102, 112. The centers can be defined, for example, as the geometric center of gravity of the respective first connecting section 102, 112. For example, the first straight line 121 can also run through the center of at least one of the connecting bolts 104, 114. In particular, the first straight line can run through one of the holes 105, 115 of one of the connecting bolts 104, 114, in particular through its center.

[0122] A second straight line 122 can be laid through the second connecting sections 106, 116. The second straight line 122 runs, for example, essentially through the centers of the connecting sections 106, 116. For example, the straight line can also run through at least one of the openings 108, 118 of the first connecting sections 106, 116, in particular through their center.

[0123] The second connecting sections 106, 116 are each located on opposite sides of the first straight line 121. In the embodiment shown, there is no overlap between the first straight line 101 and either of the two second connecting sections 106, 116.

[0124] The first connecting sections 101, 112 are arranged on a common side of the second straight line 122. In the embodiment shown, there is in particular no overlap between the second straight line 122 and either of the two first connecting sections 102, 112.

[0125] The first straight line 121 and the second straight line 122 can intersect at an intersection point 123, in particular in the common conductor plane of the at least two connecting flat parts 100, 110. The intersection point 123 can be arranged in particular in the conductor plane between the second connecting section 106 of the first connecting flat part 100 and the second connecting section 116 of the second connecting flat part 110. For example, as shown, the intersection point 123 of the first straight line 121 and the second straight line 122 can be arranged substantially centrally between the second region 106 and the second region 116.

[0126] Figure 2 shows three alternative designs of a transfer point 1. in Figure 2a It can be seen that the long connecting flat part 100 is narrowed in the area of ​​the recess 101. This has, compared to the embodiment in Figure 1the disadvantage of a reduced conductor cross-section of the first connecting flat part 100 in the region of the recess 101.

[0127] Figure 2b shows a further embodiment. In this embodiment, the conductor cross-section of the long flat part 100 is widened in the area of ​​the second connecting section 106 compared to the preferred embodiment in Figure 1 is with the embodiment in Figure 2b increased use of materials.

[0128] Figure 2c Finally, Fig. 1 shows an embodiment in which the two connecting flat parts 100, 110 in the guide section and in the area of ​​the second connecting sections 106, 116 are not in direct spatial proximity to each other. This embodiment has advantages over the Figure 1 shown the disadvantage of increased space requirements and lower heat transfer between the two connecting flat parts 100,110.

[0129] Figure 3shows an actual transfer point 1 comprising a housing 130.

[0130] In the three-dimensional view of the connecting flat parts 100,110, it can be seen that the connecting bolts 104,114 extend in an extension direction A from the broad side 103,113 of the respective connecting flat part 100,110.

[0131] The housing 130 may, in particular, be formed from a non-conductive material, for example, plastic, silicone, ceramic, and / or other non-conductive materials. The housing 103 may be integrally formed. In particular, the housing 130 may be cast and / or injection-molded.

[0132] First openings 134, 134' for the first connecting sections 102, 112 of the at least two connecting flat parts 100, 110 can be seen. The first openings 134, 134' are particularly Figure 3ashown upper side of the housing 130. In particular, the openings 134, 134' can be closed towards the lower side of the housing 130 opposite the upper side of the housing 130. A collar 135 can be arranged around the second openings 134, 134'. The collar 135 can, in particular, circumferentially enclose at least one or the at least two second openings 134, 134'. In particular, the collar 135 can extend substantially along the extension direction A of at least one of the connecting bolts 104, 114.

[0133] Second openings 132, 132 are also provided in the housing. In particular, second openings 132, 132' for the second connecting sections 106, 116 are provided on the housing 130. The second openings 132, 132' can in particular lead to the Figure 3ashown upper side of the housing 130, as well as to the opposite lower side of the housing 130. At least one of the second openings 132, 132' can be formed as a through-hole. In this way, it is possible for at least one and / or the at least two side regions 106, 116 to be accessible from both broad sides of the respective connecting flat part 100, 110 through the housing 130. For example, an object, in particular a screw, can be passed through at least one of the openings 108, 118, which are arranged in a second connecting section 106, 116 of at least one of the connecting flat parts 100, 110.

[0134] The second openings 132, 132' can be enclosed by a collar 133. The collar 133 can extend substantially parallel to the surface normal to the broad side 103, 113 and / or parallel to the extension direction of at least one of the openings 108, 118 in the second connecting section 106, 116 of at least one of the connecting flat parts 100, 110.

[0135] The housing 130 can also include at least one seal 136. The seal 136 can, in particular, have at least one, two, three, and / or more ribs. The seal 136 can, in particular, be arranged circumferentially around the at least two first sections 102, 112. In one exemplary embodiment, the seal 136 can be manufactured with the housing 130 in a joint process, for example, in a two-component injection molding process.

[0136] Fasteners 138 can be arranged in the housing 130. In the embodiment shown, these are screw receptacles 138. For example, as shown, threads 138 made of a metal material can be embedded in the housing. In this way, screws, for example, can be received in the screw receptacles 138. Because the screw receptacles 138 are formed from a metal material, they can absorb high forces.

[0137] How Figure 3a can be seen, the fastening means 138 are enclosed by the seal 136.

[0138] The transfer point 1 in question may further comprise at least one temperature sensor 142. In particular, the at least one temperature sensor 142 may be arranged in the housing 130. In particular, the temperature sensor 142 may be partially enclosed by the housing 130. Additionally and / or alternatively, the temperature sensor 142 may be at least partially exposed by an opening in the housing 130, as shown in Figure 3a shown. Housing 130 may, in particular, expose a receptive area of ​​temperature sensor 142. In particular, a collar may at least partially enclose the temperature sensor.

[0139] The temperature sensor 142 can be arranged in particular in spatial proximity to at least one of the at least two connecting flat parts 100, 110. In particular, the temperature sensor can be arranged in direct spatial proximity to the at least two first regions 102, 112 of the at least two connecting flat parts 100, 110. In Figure 3aIt can be seen how the temperature sensor 142 is arranged between the first regions 102, 112 of the at least two connecting flat parts 100, 110. Due to the direct proximity of the temperature sensor 142 to both the first connecting flat part 100 and the second connecting flat part 110, the temperature of both current-carrying connecting flat parts 100, 110 can be detected with just one sensor. The temperature sensor is electrically insulated from the at least two connecting flat parts 100, 110.

[0140] The transfer point 1 in question can also include a fuse 140. The fuse 140 can fulfill the function of de-energizing at least one and / or the at least two connecting flat parts 100, 110 if the housing 130 is unlocked. For example, this can be an HVIL fuse 140.

[0141] The fuse 140 and / or the temperature sensor 142 can each have at least one connecting line 144. These are led out of the housing 133. In particular, the lines of the fuse 140 and / or the temperature sensor 142 can be led through the housing 130, in particular injection-molded and / or cast therein. The connecting lines 144 are in particular on one of the Figure 3a shown upper side of the housing 130 facing away from the lower side of the housing 130.

[0142] Figure 3b shows the elements of Figure 3a, namely the at least two connecting flat parts 100,110, as well as the housing 130. The connecting flat parts 100,110 are arranged within the housing 130. It can be seen that the second connecting sections 106,116 are countersunk in the collar 132 of the housing 130. This can mean that the collar 132 projects beyond the broad side 103,113 in the direction of the surface normal to at least one of the broad sides 103,113 of at least one of the connecting flat parts 100,110. In particular, the collar 132 can be arranged on both sides of at least one and / or the at least two connecting flat parts 100,110, ie both on the Figure 3b shown top side of the housing 130, as well as on the underside of the housing 130 facing away from this.

[0143] It can also be seen that the connecting bolts 104,114 protrude beyond the collar 135 of the housing 130 in their extension direction A.

[0144] The fuse 140 can protrude beyond at least one of the at least two connecting bolts 104,114 in the direction of extension A.

[0145] The connecting flat parts 100,110 can be cast and / or injection-molded in the housing 130.

[0146] Figure 4 shows a case closure 150.

[0147] The housing closure 150 may be formed from a non-conductive material, such as plastic, silicone, glass, ceramic, and / or other non-conductive materials.

[0148] The housing closure 150 can have fastening means 152. In the embodiment shown, the fastening means 152 are formed as passages 152 for screws 160. The passages 152 are formed, in particular, from a metal material. The passages 152 are, in particular, embedded in the housing closure 150.

[0149] The housing cover 150 is suitable for the housing 130 in the Figure 3shown upper part of the housing 130. In particular, the housing cover 150 can rest on the seal 136 of the housing 130.

[0150] A screw 106 can be guided through at least one of the passages 152. A sealing ring 162 can be arranged on at least one of the screws 160. This can be particularly advantageous since the fastening means 138 of the housing 130 are arranged within the seal 136. The sealing rings 162 prevent moisture and / or other environmental influences from penetrating the interior of the housing 130, which is enclosed by the seal 136, via the screw passages 152.

[0151] The housing cover 150 further comprises at least one opening 154, through which, in particular, at least one of the connecting bolts 104, 114 of the at least two connecting flat parts 100, 110 can be guided. At least one or, as shown, both openings 154 can have a collar, which extends, for example, substantially perpendicular to the surrounding surface of the housing closure 150 and / or substantially parallel to the direction of extension A of at least one of the connecting bolts 104, 114.

[0152] Also visible in Figure 4that a receptacle 156 is provided in the housing cover 150 for the fuse 140. The fuse 140 can engage in the receptacle 156 when the housing closure 150 rests on the housing 130. In particular, the fuse 140 projects beyond the at least one connecting bolt 104, 114. For example, the cross-section of the receptacle 156 can be adapted to a portion of the fuse 140. Because the fuse 140 is inserted into the receptacle 156 when the housing closure 150 is placed on the housing 130, the fuse 140 is protected from environmental influences, in particular from high temperatures inside the housing.

[0153] As explained above, screws 160, for example, can be inserted into the fastening means 138, in particular into screw receptacles 138 of the housing 130, through the fastening means 152 of the housing closure 150. The fastening means 138, 152, 160 can, in particular, establish a contact pressure between the housing 130 and the housing closure 150. In particular, a press fit can be established between at least the housing closure 150 and the seal 136 of the housing 130 by means of the fastening means 136, 152, 160. The housing closure 150 can therefore be press-fitted against the housing 130 indirectly via the seal 136. In this way, it can be ensured that the interior of the housing 130 is protected from environmental influences.

[0154] The housing closure 150 can include a seal. The seal can, in particular, have a substantially identical profile to the seal 136 of the housing 130. In particular, the seal of the housing closure 150 can circumferentially encompass the openings 154 and / or the fastening means 152. The seal of the housing closure 150 can be designed as a separate component. It is also possible to manufacture the seal of the housing closure 150 together with the housing closure 150 using a two-component injection molding process.

[0155] As in Figure 5 As shown, a wall 170 may be arranged between the housing 130 and the housing closure 150.

[0156] The wall 170 can, for example, be formed from a conductive material such as a metal material, for example, aluminum, copper, and / or other metal materials and / or alloys thereof. It is also possible to form the wall 170 from a non-conductive material, for example, plastic, ceramic, glass, and / or other non-conductive materials.

[0157] The wall 170 may in particular comprise at least one recess 172. At least one of the recesses 172 may be positioned such that it is aligned with a fastening means 138 of the housing 130 and / or a fastening means 152 of the housing closure 150. In particular, at least one of the recesses 172 may be suitable for guiding a screw 160 through it. A plurality of recesses 182 may also be provided, for example, as shown in Figure 5 shown, four recesses 172.

[0158] The wall 170 can include an opening 174. The openings 174 can be positioned in the wall 170 such that the first connection areas 102, 112 of the transfer support point 1 in question can be reached through them. The opening 174 can also allow the fuse 140 and / or the temperature sensor 142 to be passed through it. In one exemplary embodiment, the opening 174 comprises the at least two connection bolts 104, 114 of the transfer support point 1 in question. In particular, at least one and / or the at least two connection bolts 104, 114 can be passed through the wall 170 in the region of the opening 174.

[0159] The size of the opening 174 of the wall 170 is in particular smaller than the area of ​​the housing 130 encompassed by the seal 136. In particular, the seal 136 of the housing 130 bears against the wall 170 essentially continuously along the seal 136. Thus, a substantially gas-tight, liquid-tight, and / or pressure-tight connection can be established between the seal 136 of the housing 130 and the wall 170.

[0160] The housing cover 150 can at least partially contact the wall 170. In particular, the housing cover 150 can contact the wall 170 in an area that circumferentially encloses the recesses 172. For example, the housing closure 150 can rest against the wall 170 by means of a seal of the housing closure 150.

[0161] By means of the fastening means 138, 152, 160, a press fit can be created, in particular, between the housing cover 150 and the wall 170, on the one hand, and / or between the housing 130 and the wall 170, on the other hand. In particular, a seal 136 can be arranged, in particular with a press fit, between the wall 170 and the housing 130. A seal can be arranged, in particular with a press fit, between the wall 170 and the housing closure 150.

[0162] The wall 170 can, for example, perform a securing function. For example, the wall 170 can form part of an area enclosing an energy storage device, for example, in a vehicle. The wall 170 can thus provide a spatial separation between an energy storage device and the remaining energy supply structure.

[0163] Figure 6 shows an application of the transfer point 1 in question to an energy storage device 200.

[0164] The direction-changing function of the transfer point 1 can be seen. It is also possible to imagine how the energy storage device 200 can be enclosed by a wall 170 (not shown).
