Description

Technical Field

[0001] This invention relates to an EMV housing, an EMV housing component, and the use of the EMV housing. The housing or housing component is particularly used to ensure electromagnetic compatibility (EMV) by shielding electrical components relative to their surrounding environment when arranging them. Background Technology

[0002] Shielding electrical or electronic components is used to keep them away from electric and magnetic fields, especially at higher frequencies, or conversely, to protect the surrounding environment from fields emanating from the component.

[0003] In particular, shielding is achieved through conductive metal sheets, foils, or layers connected to (ground, reference potential, or ground). Examples of such shielding include metal vapor-deposited plastic foil, aluminum foil laminated paper, graphite, and conductive varnish layers. Furthermore, it is known to coat plastic housings with metal layers.

[0004] The shielding layer is particularly implemented as a housing or housing component, wherein the housing encloses a volume in which at least one (to be shielded) electrical component is arranged. The housing must also be able to secure the component arranged therein, thus typically a so-called EMC mounting plate is arranged within the housing.

[0005] Such housings are typically implemented in multiple parts. For example, the housing includes a cover area (first housing part), a base area (second housing part), and an assembly plate (third housing part) disposed between the base area and the cover area. Here, the assembly plate extends within the housing volume surrounded by the base area and the cover area, and constitutes a sub-volume of that volume.

[0006] For electromagnetic shielding, it is important that the various components of the enclosure are connected to each other with the lowest possible impedance and that a common potential (grounding connection) is established. To this end, it is necessary to ensure that the various enclosure components are electrically connected to each other and to ground or reference potential. Summary of the Invention

[0007] The objective of this invention is to at least partially solve the problems listed with reference to the prior art. In particular, it is proposed to provide a housing or a housing component for a housing that can be manufactured cost-effectively and in which effective shielding of electrical components can be achieved.

[0008] The use of a housing having the features of claim 1, a housing member having the features of claim 12, and a housing having the features of claim 13 helps to solve these tasks. Advantageous improvements are the subject of the dependent claims. Features listed individually in the claims can be combined with each other in a technically meaningful manner and can be supplemented by illustrative facts in the specification and / or details in the drawings, which show further embodiments of the invention.

[0009] An EMV housing (hereinafter also referred to as "housing") for electrical components (e.g., inverters, especially inverters, converters, etc. used in motor vehicles) is proposed.

[0010] The EMV housing includes at least a first housing member and a second housing member, which are connected to each other by a sealing surface and together enclose a volume of the housing in a liquid-tight manner. Within this volume, a plate-shaped third housing member is arranged between the first and second housing members. The third housing member has a plurality of elastically deformable contact elements in at least one connection region with at least one of the first and second housing members, for constructing a conductive connection between the housing member and the housing. When the housing member is connected to the housing, the contact elements elastically deform upon contact with the respective housing member.

[0011] EMV housings are particularly shape-stable housings, which therefore undergo only plastic deformation rather than elastic deformation, with little or no elastic deformation. The same applies particularly to the first housing component, the second housing component, and, with limitations, also to the third housing component.

[0012] The enclosure is particularly used for shielding components arranged within the volume from the surrounding environment. Here, the effects of electromagnetic radiation from the surrounding environment through the components within the enclosure, and the effects of electromagnetic radiation from the surrounding environment acting on the components arranged within the enclosure, must be considered. Additionally, the enclosure should also enable the fixed arrangement of the components therein, thus typically accommodating a so-called EMC mounting plate (a third enclosure component) within the volume.

[0013] The housing components are in particular interconnected, thereby achieving a uniform ground potential.

[0014] The first housing member is particularly the upper (upper half) or cover member, and the second housing member is particularly the lower (lower half) or base member. The first and second housing members are connected to each other, particularly by sealing surfaces, and surround the volume in a liquid-tight and, if necessary, equally airtight manner. A third housing member may at least form the sealing surface, or may be (completely) disposed within the volume. The third housing member is particularly used as an assembly plate for components disposed within the volume. Alternatively or additionally, the third housing member is used to divide the volume into multiple sub-volumes, wherein these sub-volumes are then shielded from each other by the third housing member.

[0015] The third housing component is particularly plate-shaped. In particular, it is implemented as a plate component.

[0016] The third housing member has a plurality of elastically deformable contact elements in at least one connection region with at least one of the first and second housing members, for constructing an electrical connection between the housing members. In the connection region, the third housing member contacts either the first housing member or the second housing member, or both housing members. Here, the third housing member contacts the first housing member, particularly (only) on its upper side, and contacts the second housing member, particularly (only) on its lower side.

[0017] The contact elements that enable contact with other housing components are particularly elastically deformable.

[0018] When housing components are connected to the housing, the contact elements undergo at least or only elastic deformation (optionally, plastic deformation also occurs) through the housing components that contact the corresponding contact elements. This means that the contact elements are in an undeformed state before the first assembly of the housing, and then deform within the assembly process. This also specifically means that the contact elements are under prestress during the assembled state of the housing.

[0019] If the housing is disassembled again and the housing components are separated from each other, the contact elements can elastically (at least partially) spring back.

[0020] In particular, multiple contact elements in the connection area are arranged side by side (along the extension direction) and separated from each other by at least one (or exactly) slit. Two or more slits may also be arranged between at least two of the multiple contact elements, wherein a correspondingly different shaped area of ​​the third housing member (different from the contact element shape) exists between the slits.

[0021] The slit, in particular, is an opening in the third housing member that extends from the upper side to the lower side of the third housing member. The slit is especially elongated, i.e., having a length that is 2 to 50 times the opening.

[0022] The slits in the connecting areas are generally parallel to each other, or generally transverse to the straight line of the connecting areas, or, if necessary, curved in the same direction (extension direction).

[0023] In particular, the slit can extend in a straight line, but it can also have a curved direction along its length.

[0024] This slit is particularly useful for contact elements arranged between two slits that can deform (elastic deformation, with additional plastic deformation if necessary) independently of each other or independently of the area of ​​the third housing member surrounding them.

[0025] In particular, the contact elements are arranged side by side in the connection area along the extension direction, and at least one slit has a length of 5 to 50 mm, especially 10 to 30 mm, preferably 15 to 20 mm, extending transversely to the extension direction.

[0026] In particular, at least one of the contact elements between the two slits has a width of 5 to 20 mm, especially 7 to 15 mm.

[0027] In particular, at least one slit has an opening of 0 to 5 mm, especially 0.2 to 5 mm, preferably 0.4 to 2.5 mm (extending laterally along the length). This opening is particularly constant along the length. The slit can be created, for example, by material separation (possibly with an opening of zero mm) or, for example, by material removal (possibly with an opening greater than zero mm).

[0028] In addition to the (first) slits arranged between the contact elements, additional (second) slits may be provided, particularly at the corresponding ends of the length of the (first) slits and extending laterally thereto. These (second) slits narrow the transition between the contact elements and the surface area surrounding the contact elements without cutting it off.

[0029] In particular, the above embodiments are applicable to at least 40%, preferably at least 60%, particularly preferably at least 80%, or even all contact elements and / or slits.

[0030] In particular, the dimensions of length, width, and opening are measured in the projection of the element onto a plane extending laterally in the height direction.

[0031] In particular, the corresponding contact element is defined by the length of the slit and the width of the contact element, wherein the contact element comprises between 0.5% and 80% of the total area of ​​the third housing member (i.e., the area on the upper side or the area on the lower side, especially as a projection onto a plane defined, for example, by the periphery of the third housing member), particularly between 5% and 20%.

[0032] In particular, the contact element extends 25% to 90%, especially 50% to 75%, through the periphery of the third housing member.

[0033] In particular, the third housing member extends substantially in a plane. Here, the third housing member has a flat surface area on one hand, and a contact element or connection area on the other. The height direction extends particularly laterally to this plane. The contact element extends particularly from a first height of the surface area to a second height. The second height can be located above or below the plane. The distance between the first and second heights is particularly between 0.5 and 10 mm, preferably between 2 and 5 mm.

[0034] In particular, the surface of the contact element (i.e., between the two slits and along its length) is curved, meaning that the contact element has a curved or other curved orientation along the direction parallel to the extension of the slits, such as a serrated or zigzag or other orientation. This results in a region that protrudes relative to the surface area surrounding the contact element (having a first height), having another (second) height.

[0035] In particular, the contact elements are arranged side-by-side along the extension direction in the connection area and deform relative to the height direction by the connection of the housing members. In the undeformed state (i.e., before the housings are joined together and before the contact elements undergo elastic deformation), the contact elements have the same or different heights along the extension direction. The different heights can vary by 5% to 200%, and especially 50% to 150%, of the maximum distance. On the one hand, this means that the contact elements extend relative to the plane (first height) to a second height of the same corresponding amount in opposite height directions. On the other hand, this means, for example, that between two contact elements extending to the same second height, the contact element extends to a slightly smaller second height. Therefore, for example, the contact element extending to the higher height deforms more (elastically) than the contact element extending to the lower height.

[0036] In particular, among the two side-by-side contact elements, the first contact element contacts only the first housing component, and the second contact element contacts only the second housing component.

[0037] In particular, the third housing member extends in the central plane along the extension direction in the connection area, and of the two side-by-side contact elements, the first contact element points from the central plane toward the first housing member, and the second contact element points from the central plane toward the second housing member. Specifically, this means that these contact elements extend relative to the plane or the central plane (first height) in opposite height directions to a second height of the same or different magnitudes.

[0038] In particular, the contact elements are arranged side-by-side along the extension direction in the connection area and deformable relative to the height direction by the connection of the housing members. In particular, at least one contact element has a height that varies along the extension direction in its undeformed state. In particular, the contact elements adjacent to the two slits that limit the contact elements have a maximum second height (hereinafter also referred to as the maximum value) and a minimum second height (minimum value) between these two maximum second heights (maximum values). In particular, the minimum second height (minimum value) is also greater than the first height.

[0039] In particular, at least one contact element has a contact surface with a structure that contacts and damages the surface of the corresponding housing element when the contact element elastically deforms. "Damage" specifically refers to, for example, the destruction of an oxide layer present on the surface of the housing element by the edges and deformation of the contact element, thereby ensuring a conductive connection between the housing elements through the contact element.

[0040] The structure can, for example, have sharp edges (edge ​​radius less than 0.2 mm, especially less than 0.1 mm; adjacent surfaces of the edges have angular values ​​of 20 to 160 degrees). The structure can, for example, be formed by the edges of the contact element adjacent to the slit. In the undeformed state (i.e., before the housings are joined together and before the contact element elastically deforms), these edges point towards the housing member, such that the edges themselves contact the housing member. In particular, the surfaces of the contact element adjacent to the edges extend at an angle of at least 20 to 120 degrees to the contact surface (housing member surface) of the housing member.

[0041] In particular, the third housing component is made of a metallic material. Any conductive material is especially suitable as a metallic material, especially one whose conductivity lies between that of aluminum (as a cost-effective material) and copper (as a material with high conductivity).

[0042] In particular, the sealing surface between the first housing member and the second housing side is implemented to completely surround the volume. Therefore, the sealing surface extends particularly around the respective housing member or the (sub)volume surrounded by it. The corresponding seal (e.g., a common non-conductive seal or a substantially known conductive EMC seal) extends particularly along the sealing surface, and also similarly completely surrounds it.

[0043] In particular, the conductive connection between the first housing member and the second housing member is ensured by the third housing member. Here, connecting elements (e.g., screws or rivets) used to connect the first housing member and the second housing member can also form a conductive connection, but these are generally insufficient for low-impedance connections of the housing members.

[0044] Furthermore, a housing component of the EMV housing is proposed, wherein the housing component is a third housing component.

[0045] In addition, the use of the EMV housing as an inverter, an electrical component, is proposed.

[0046] In particular, EMV housings are provided for placement in motor vehicles, especially as housings for electrical components used in conjunction with the traction drive or motor of the motor vehicle.

[0047] The implementation scheme for EMV housings can be adapted to third housing components and applications, and vice versa.

[0048] The use of indefinite articles (“a” and “an”), especially in the claims and the description thereof, should be understood as themselves, and not as numerals. Accordingly, any term or component introduced therein should therefore be understood to exist at least once, and in particular may exist multiple times.

[0049] For the sake of caution, it should be noted that the numerals used herein (“first,” “second,” etc.) are primarily (only) used to distinguish multiple similar objects, parameters, or processes, and therefore do not necessarily indicate any relationship and / or order between these objects, parameters, or processes. If a relationship and / or order is required, it is expressly stated herein, or will become apparent to those skilled in the art upon examination of the specifically described design. Where a component may appear multiple times (“at least one”), a description of one of these components may equally apply to all or some of the multiple components, but this is not mandatory.

[0066] Figure 1 A known assembly of an inverter (electrical component 2) and a motor 22 is shown. The assembly includes the electrical component 2 with an EMV housing 1, the motor 22, its electrical connections 23, and signal lines 24.

[0067] Figure 2 The inverter is shown in side view, section, and enlarged detail. Figure 3 The inverter is shown in perspective. Figure 2 and Figure 3 The following sections describe them together. References are available for... Figure 1 The explanation.

[0068] The electrical components 2 of the inverter shown here are arranged in the EMV housing 1. The housing 1 is used to ensure electromagnetic compatibility (EMV) by shielding the electrical components 2 relative to the surrounding environment 25 when arranging them.

[0069] The shielding of electrical or electrical component 2 is used to keep it away from electric and magnetic fields, especially at higher frequencies, or conversely, to protect the surrounding environment 25 from fields originating from component 2.

[0070] Shielding is achieved through conductive housing components 3, 4, and 7 connected to ground 27. Housing components 3 and 4 enclose volume 6, in which the electrical components 2 (to be shielded) are arranged. It is essential to ensure that each individual housing component 3, 4, and 7 is conductively connected to ground 27.

[0071] In a multi-piece housing 1, attention must also be paid to ensuring at least a liquid-tight (and if necessary, even a gas-tight) seal of the volume 6 enclosed by the housing 1 relative to the surrounding environment 25. For example, it is known that non-conductive sealing elements can be provided in the areas of the sealing surfaces 5 of the housing parts 3,4 that are in contact with each other, wherein the conductive connection of the individual housing parts 3,4 is ensured, for example (only or primarily) by connecting elements 26 (e.g., screws). Alternatively, known EMC seals can be used in the areas of the sealing surfaces.

[0072] Figure 4 The perspective view shows the cross-section based on Figure 2 The lower part of the inverter. Figure 5 As shown in the view above, according to Figure 4 The third housing component 7 used in the inverter. Figure 6 The inverter is shown in cross-section from a side view. Figure 2 A magnified view of the local area. Figure 7 The perspective view shows the cross-section based on Figure 2 Details of the inverter. Figures 4 to 7 The following sections describe them together. References are available for... Figures 1 to 3 The explanation.

[0073] EMV housing 1 includes a first housing component 3 (see...) Figure 2 , 3 The first housing member 3 and the second housing member 4 are connected to each other by a sealing surface 5 and together enclose the volume 6 of the housing 1 in a liquid-tight manner. Within the volume 6, a plate-shaped third housing member 7 is arranged between the first housing member 3 and the second housing member 4. The third housing member 7 is positioned relative to the first housing member 3 (e.g., 6) and the second housing member 4. Figure 7 At least one of the housing members 3, 4, 7 and the second housing member 4 has a plurality of elastically deformable contact elements 9, 10 in a plurality of connection regions 8 for constructing an conductive connection between the housing members 3, 4, 7 and each other. When the housing members 3, 4, 7 are connected to the housing 1, the contact elements 9, 10 are elastically deformed by contacting the corresponding housing member 3, 4 with the contact element 9, 10.

[0074] EMV housing 1 is a shape-stable housing 1, that is, it is inelastic or only slightly elastic and only plastically deformable. The same applies to the first housing part 3, the second housing part 4, and also to the third housing part 7 (the contact elements 9, 10 of the third housing part 7 are elastically deformable) under certain limitations.

[0075] Housing components 3, 4 and 7 are connected to each other, thereby achieving a unified ground potential.

[0076] The first housing member 3 is an upper (upper half) or cover plate, and the second housing member 4 is a lower (lower half) or base member. The first housing member 3 and the second housing member 4 are connected to each other by a sealing surface 5 and surround the volume 6 in a liquid-tight (and, if necessary, airtight) manner. The third housing member 7 is completely disposed within the volume 6. The third housing member 7 serves as an assembly plate for the component 2 disposed within the volume 6. Additionally, the third housing member 7 serves to divide the volume 6 into sub-volumes, wherein these sub-volumes are shielded from each other by the third housing member 7.

[0077] The third housing component 7 is designed as a plate. It is actually a modified plate component.

[0078] The third housing member 7 has a plurality of elastically deformable contact elements 9, 10 in the connection region 8 for constructing an conductive connection between housing members 3, 4, 7 and each other. In the connection region 8, the third housing member 7 only contacts either the first housing member 3 (e.g., ...). Figure 7 The third housing member 7 may contact the first housing member 3 only on its upper side and the second housing member 4 only on its lower side.

[0079] The contact elements 9 and 10 that come into contact with other housing parts 3 and 4 are elastically deformable.

[0080] When housing components 3, 4, 7 are connected to housing 1, the housing components 3, 4, and 5, through contact with the corresponding contact elements 9, 10, cause the contact elements 9, 10 to undergo at least or only elastic deformation (optionally, additionally, plastic deformation also occurs). That is, before the first assembly of housing 1, the contact elements 9, 10 are in an undeformed state (e.g., see...). Figure 5 , 8 (up to 12 and 14), and deformation occurs within the scope of assembly (e.g., see...). Figure 13 and 15 In other words, in the assembled state of housing 1, contact elements 9 and 10 are under prestress.

[0081] Contact elements 9 and 10 are arranged side by side in the connection area 8 along the extension direction 12 and are respectively arranged apart from each other by a slit 11.

[0082] Slit 11 is an opening in the third housing member 7, extending from the upper side to the lower side of the third housing member 7 (see...). Figure 5 The slit 11 is implemented in an elongated shape, that is, it has a length 13 that is about 20 times larger than the opening 29.

[0083] The slits 11 of the connecting regions 8 are parallel to each other, or transverse to the straight line of the connecting regions 8 (e.g., along the perimeter 28, see...). Figure 5) extends, or if necessary, laterally to the direction of the bend (see also) Figure 5 (Extended in surface region 30).

[0084] Slit 11 extends accordingly along a straight line (in the view along the height direction 16).

[0085] The slits 11 are used for contact elements 9, 10 arranged between two slits 11 that can deform independently of each other or independently of the region 30 of the third housing 7 surrounding them (elastically, and additionally plastically if necessary).

[0086] Contact elements 9 and 10 are arranged side-by-side in the connection area 8 along the extension direction 12. The slits 11 of the contact elements 9 and 10, which are spaced apart at the periphery 28 (in the surface area 30), have a length 13 extending transversely to the extension direction 12 of about 25 mm. The slits 11 of the contact elements 9 and 10 arranged at the periphery 28 have a length of about 10 mm.

[0087] Contact elements 9, 10 arranged at the periphery 28 have a width 14 of 15 mm between the two slits 11. Contact elements 9, 10 arranged at intervals at the periphery 28 (in the surface region 30) have a smaller width 14 of about 10 mm between the slits 11.

[0088] The slit 11 has an opening 29 that extends laterally to the length 13 by 1 (-) mm. The opening 29 is constant along the length 13.

[0089] The corresponding contact elements 9, 10 are defined by the length 13 of the slit 11 and the width 14 of the contact elements 9, 10, wherein the contact elements 9, 10 include approximately 15% of the total area 15 of the third housing 7 (i.e., the area on the upper side or the area on the lower side, as a projection onto the plane 18, which is defined, for example, by the periphery 28 of the third housing 7).

[0090] Contact elements 9 and 10 extend about 70% of the extension of the periphery 28 of the third housing member 7.

[0091] The third housing member 7 extends substantially within the plane 18. Here, the third housing member 7 has a flat surface region 30 on one hand, and contact elements 9, 10 or connecting regions 8 on the other. The height direction 16 extends transversely to the plane 18. The contact elements 9, 10 extend from a first height 17 of the surface region 30 to a second height 31. The second height 31 can be located above or below the plane 18 (in...). Figure 7 (For example, above). According to Figure 7 In the contact element, the distance 32 between the first height 17 and the second height 31 is, for example, 7 mm.

[0092] The surfaces of contact elements 9 and 10 (i.e., between the two slits 11 and along the length 13) are bent and deformed; that is, contact elements 9 and 10 have a curved or other curved orientation along the direction of extension parallel to the slits 11 (see...). Figure 4 , 7 Thus, a region is formed that protrudes relative to the surface region 30 with a first height 17 surrounding the contact elements 9, 10, and has a different second height 31.

[0093] Figure 8 A view transverse to the extension direction 12 according to Figure 9 The view of section VIII-VIII shows a first implementation variant of contact elements 9,10. Figure 9 A view along the extension direction 12 according to Figure 8 The screenshot IX-IX shows the view according to Figure 8 Contact elements 9, 10. Figure 8 and Figure 9 The following sections describe them together. References are available for... Figures 1 to 7 The explanation.

[0094] The surfaces of contact elements 9 and 10 (i.e., between the two slits 11 and along the length 13) are bent and deformed, meaning that contact elements 9 and 10 have a curved orientation along the direction of extension parallel to the slits 11 (see...). Figure 9 Thus, a region 30 is formed that protrudes relative to the surface region 30 with a first height 17 surrounding the contact elements 9, 10, and has a different second height 31.

[0095] In the undeformed state (i.e., before the housings 1 are joined together and before the contact elements 9, 10 undergo elastic deformation), the contact elements 9, 10 each have the same second height 31 along the extension direction 12. Each of the contact elements 9, 10 has a correspondingly constant second height 31 along the extension direction 12.

[0096] Figure 10 A view transverse to the extension direction 12 according to Figure 11 The view of section XX shows a second implementation variation of contact elements 9, 10. Figure 11 A view along the extension direction 12 according to Figure 10 The view of section XI-XI in the figure shows that, according to Figure 10 Contact elements 9, 10. Figure 10 and Figure 11 The following sections describe them together. References are available for... Figure 8 and Figure 9 The explanation.

[0097] Unlike the first embodiment, the contact elements 9, 10, in their undeformed state, have a second height 31 that varies along the extension direction 12. The contact elements 9, 10 respectively adjacent to the two slits 11 that constrain them have a maximum second height 31 (maximum value), and a minimum second height 31 (minimum value) between these two maximum second heights 31 (maximum values). Here, the minimum second height 31 (minimum value) is greater than the first height 17 of the surface region 30.

[0098] Contact elements 9 and 10 have contact surfaces 19 that contact the corresponding housing parts 3 and 4, and have a structure 20, wherein, upon elastic deformation of contact elements 9 and 10, structure 20 contacts housing parts 3 and 4 and damages their housing surface 21. Structure 20 has sharp edges 33 (with very small radii, and adjacent surfaces of edge 33 having an angular value of approximately 40 degrees). Structure 20 is formed by the edges 33 of contact elements 9 and 10 adjacent to slit 11. These edges 33, in their undeformed state (i.e., before the housings 1 are joined together and before the contact elements 9 and 10 elastically deform), point toward housing parts 3 and 4 such that the edges 33 themselves contact housing parts 3 and 4. The surfaces of contact elements 9 and 10 adjacent to edges 33 extend at angles of 90 degrees and approximately 50 degrees to the contacting housing surface 21 of housing parts 3 and 4.

[0099] Figure 12 The side view shows a partial view of the first implementation variant of housing 1 before the assembly of housing parts 3, 4, and 7. Figure 13 The assembly state is shown according to Figure 12 A part of it. Figure 12 and Figure 13 The following sections describe them together. References are available for... Figures 1 to 11 The explanation.

[0100] Contact elements 9 and 10 are arranged side-by-side in the connection region 8 along the extension direction 12 and deform relative to the height direction 16 during the connection process of housing parts 3, 4, and 7. The surface region 30 of the third housing part 7 extends between the contact elements 9 and 10. In the undeformed state (i.e., before the housings 1 are joined together and before the contact elements 9 and 10 undergo elastic deformation—see…) Figure 12 Contact elements 9 and 10 each have the same second height 31 along the extension direction 12. During the assembly process of housing 1, these second heights 31 contact the first housing member 3 and continuously deform, thereby reducing the second height 31 (see...). Figure 13 In the deformed state, contact elements 9 and 10 are under prestress.

[0101] Figure 14A partial embodiment of the second variant of housing 1 is shown in sectional view from the side view before the assembly of housing parts 3, 4, and 7. Figure 15 The assembly state is shown according to Figure 14 A part of it. Figure 14 and Figure 15 The following sections describe them together. References are available for... Figures 1 to 13 The explanation.

[0102] Contact elements 9 and 10 are arranged side by side in the connection area 8 along the extension direction 12 and deform relative to the height direction 16 during the connection process of housing parts 3, 4, and 7.

[0103] Of the two side-by-side contact elements 9 and 10, the first contact element 9 contacts only the first housing part 3, and the second contact element 10 contacts only the second housing part 4.

[0104] In addition to the (first) slit 11 arranged between the contact elements 9, 10, another (second) slit 11 is provided, which is arranged at the corresponding end of the length 13 of the (first) slit 11 and extends laterally thereto. Through these (second) slits 11, the transition between the contact elements 9, 10 and the surface area 30 surrounding the contact elements 9, 10 is narrowed, but not cut off.

[0105] The third housing member 7 extends in the connecting region 8 along the extension direction 12 in the (central) plane 18. Of the two side-by-side contact elements 9 and 10, the first contact element 9 points from the central plane 18 toward the first housing member 3, and the second contact element 10 points from the central plane 18 toward the second housing member 4. This means that these contact elements 9 and 10 extend relative to the central plane 18 (first height 17) along opposite height directions 16 to a second height 31 of the same magnitude.

[0106] In the undeformed state (i.e., before the housings 1 are joined together and before the contact elements 9, 10 undergo elastic deformation—see...) Figure 14 The corresponding first contact elements 9 each have the same second height 31 along the extension direction 12. These second heights 31 are contacted and continuously deformed by the first housing member 3 during the assembly process of the housing 1, thereby reducing the second height 31 (see...). Figure 15 The same applies to the second contact element 10.

[0107] In the undeformed state (i.e., before the housings 1 are joined together and before the contact elements 9, 10 undergo elastic deformation), the contact elements 9, 10 each have a second height 31 that is different from each other along the extension direction 12. The difference between the different second heights 31 is 200% of the maximum distance 32 between the largest second height 31 and the first height 17. The contact elements 9, 10 extend relative to the (central) plane 18 (first height 17) along opposite height directions 16 to correspondingly equal second heights 31. In the deformed state, the contact elements 9, 10 are under prestress.

[0108] Contact elements 9 and 10 have contact surfaces 19 that contact the corresponding housing parts 3 and 4. These contact surfaces have a structure 20, which, upon elastic deformation of the contact elements 9 and 10, contacts the housing parts 3 and 4 and damages their housing surface 21. The structure 20 has sharp edges 33 (with very small edge radii, and adjacent surfaces of the edges 33 having an angular value of approximately 100 degrees). The structure 20 is formed by the edges 33 of the contact elements 9 and 10 adjacent to the slit 11. In the undeformed state (i.e., before the housings 1 are joined together and before the contact elements 9 and 10 undergo elastic deformation), these edges 33 point towards the housing parts 3 and 4, such that the edges 33 themselves contact the housing parts 3 and 4. The surfaces of the contact elements 9 and 10 adjacent to the edges 33 extend at an angle of approximately 50 degrees to the contacting housing surface 21 of the housing parts 3 and 4.

[0109] In its undeformed state, the contact elements 9, 10 have a second height 31 that varies along the extension direction 12. The contact elements 9, 10 respectively adjacent to the two slits 11 that constrain them have a maximum second height 31 (maximum value) and a minimum second height 31 (minimum value) between these two maximum second heights 31 (maximum values). Here, the minimum second height 31 (minimum value) is greater than the first height 17 of the surface region 30.

[0110] The conductive connection between the first housing member 3 and the second housing member 4 is also ensured by the third housing member 7. However, screws can also serve as connecting elements 26, which are used to connect the first housing member 3 and the second housing member 4 and ensure the conductive connection.
