Description

[0001] Seal, sealing arrangement and housing

[0002] The present invention relates to a seal for arrangement between a first object and a second object, in particular for sealing a first fluid chamber from a second fluid chamber or several fluid chambers. The invention further relates to a seal arrangement and a housing, in particular a battery housing or a control housing.

[0003] Seals, such as elastomer seals, are known from the prior art for sealing fluid spaces between two components or objects. Housings made of a metallic material are typically used to shield electromagnetic radiation. The housing elements of such a housing are sealed to protect against moisture and dirt. However, the use of elastomer seals does not provide an electrically conductive connection between the housing elements, thus impairing the shielding of electromagnetic radiation.

[0004] The present invention is based on the objective of providing a seal that has a simple and cost-effective design, ensures a reliable electrically conductive connection and enables a sealing of a first fluid chamber from a second fluid chamber.

[0005] This problem is solved by a seal for arrangement between a first object and a second object, in particular to seal a first fluid space from a second fluid space or several fluid spaces, comprising at least one support element forming a preferably dimensionally stable base body, and at least one elastic sealing element arranged on the support element, wherein at least one contact element projecting from the support element is provided, which, when the seal is arranged between the first and second object, forms an electrically conductive contact between the first object and / or the second object.

[0006] The seal is preferably a carrier seal, in particular a metal-elastomer seal and / or a plastic carrier seal. Such a seal is used in particular to seal the first object, for example a housing component, and the second object, for example another housing component or a cover element, from each other and at the same time to form an electrically conductive connection to the first object and / or the second object.

[0007] The seal can comprise either a single support element or multiple support elements.

[0008] Preferably, the seal can comprise two or more support elements that can be connected or joined to each other, either directly or indirectly, each forming a preferably dimensionally stable base body and on which at least one elastic sealing element is arranged.

[0009] The support elements are, in particular, directly or indirectly connectable to one another or connected to one another in such a way that the support elements, together with the at least one sealing element arranged thereon, complete the seal. In particular, the support elements abut each other at least partially in a circumferential direction, preferably butt-jointed.

[0010] In the context of this description and the attached claims, a direct connection of the support elements is understood in particular to mean that the support elements are connected or connectable to each other without the aid of further components.

[0011] For the purposes of this description and the attached claims, an indirect connection of the support elements is understood to mean in particular that the support elements are connected or connectable to one another by means of one or more additional components.

[0012] For example, the support elements can be indirectly connected to each other via the first and / or the second object, in particular by arranging the support elements between the first and the second object. Likewise, the support elements can be indirectly connected to each other via the at least one sealing element or via an additional, preferably elastomeric, component.

[0013] The at least one support element forms, in particular, a preferably dimensionally stable base body of the seal.

[0014] In particular, at least one support element forms a basic body for providing a load-bearing function for the seal.

[0015] In the context of this description and the attached claims, a load-bearing function is understood in particular to mean the transmission of compressive forces, especially between two objects or components.

[0016] Preferably, the at least one sealing element forms an elastic sealing body to provide a sealing function of the seal.

[0017] The at least one support element with the at least one sealing element arranged on it is preferably ring-shaped, in particular ring-shaped and closed.

[0018] If the seal comprises several support elements, the support elements preferably form segments of an annularly closed seal.

[0019] In particular, the interconnected support elements, together with the at least one sealing element arranged on them, form a closed ring shape.

[0020] For the purposes of this description and the attached claims, a ring shape is understood to mean, in particular, a closed shape of the seal. The ring shape of the seal can, in particular, be a polygonal shape, an annular shape, or a shape other than a polygonal or annular shape.

[0021] Preferably, the at least one support element is made of a material that is at least approximately inflexible or rigid. More preferably, the at least one support element is made of a material that is at least partially metallic, a plastic material, and / or a composite material.

[0022] In particular, at least one support element is made of a material that is at least partially electrically conductive.

[0023] The seal and / or the at least one support element of the seal is preferably designed as a flat surface.

[0024] The seal and / or the at least one support element of the seal extends, in particular at least approximately, along a plane, especially along a principal extension plane, of the seal.

[0025] The at least one elastic sealing element is preferably manufactured by injection molding, compression molding and / or transfer compression molding.

[0026] In particular, at least one elastic sealing element is injection-molded onto at least one support element.

[0027] In the context of this description and the attached claims, injection molding is understood in particular to mean joining the at least one elastic sealing element with the at least one support element, wherein the at least one elastic sealing element is produced in an injection molding process such that it is attached to the at least one support element.

[0028] At least one elastic sealing element is, in particular, an injection-molded part.

[0029] The contact element projecting from the support element can preferably enable only partial contact between the first object and / or the second object.

[0030] In particular, the at least one contact element is designed to bridge a gap between the at least one support element and the first and / or second object, especially to a conductive section of the first and / or second object, in a mounting position of the seal. The at least one contact element can form a contact surface or a contact point pointing away from the support element, which can be brought into contact with the first and / or the second object.

[0031] Likewise, at least one contact element can be designed to extend at least sectionally along the support element.

[0032] Preferably, at least one contact element can be formed which forms a contact surface extending at least sectionally along the support element.

[0033] Further development of the seal may also provide that the at least one contact element is formed from the at least one support element, is formed into the at least one support element, is formed onto the at least one support element or is attached to the at least one support element.

[0034] In particular, the at least one contact element can be formed on the at least one support element by a forming process and / or by a primary forming process.

[0035] The at least one support element and the at least one contact element can be formed together by such a forming process and / or primary forming process, or by separate forming processes and / or primary forming processes.

[0036] Furthermore, it may preferably be provided that the at least one contact element is punched out and / or stamped into the at least one support element.

[0037] The at least one contact element can also be attached or fastened to the at least one support element, for example by welding, soldering, gluing, or the like. In a preferred embodiment of the seal, the at least one contact element can be formed integrally with the at least one support element.

[0038] In other words, at least one support element and at least one contact element are formed in one piece.

[0039] Through the integral design of at least one support element and at least one contact element, these together can form the dimensionally stable basic body.

[0040] Preferably, the at least one support element and the at least one contact element are formed from the same, in particular electrically conductive, material by integral design.

[0041] A particularly advantageous embodiment of the seal can provide that the at least one contact element has a height relative to a surface of the at least one support element which is at least about 0.02 mm and at most about 0.5 mm.

[0042] The term "surface of the at least one support element" refers in particular to a surface section of the at least one support element that points towards the first object and / or the second object.

[0043] Preferably, the height of the at least one contact element relative to the surface of the at least one support element can be at least approximately 0.03 mm.

[0044] Particularly preferably, the height of the at least one contact element relative to the surface of the at least one support element can be at least approximately 0.05 mm.

[0045] Preferably, the height of the at least one contact element relative to the surface of the at least one support element can be at most approximately 0.3 mm.

[0046] Particularly preferably, the height of the at least one contact element relative to the surface of the at least one support element can be at most approximately 0.2 mm. In particular, the height of the at least one contact element relative to the surface of the at least one support element can be at most approximately 0.15 mm.

[0047] In a further development of the seal, at least one contact element can be designed as a raised area, a shaped feature, a projection, a tab, a cup, a bridge, a rib, a stamp, a pin or the like.

[0048] In particular, the at least one contact element can have any geometric configuration suitable for bridging a gap between the at least one support element and the first object and / or second object.

[0049] Preferably, the raised area, the shaped feature, the projection, the tab, the cup, the bridge, the strip, the stamp, the pin or the like can be designed to form a contact surface or contact point pointing towards the first object and / or the second object for contacting the first object and / or the second object.

[0050] Preferably, the elevation, shape, projection, tab, cup, bridge, strip, stamp, pin or the like is formed, molded, molded onto, or attached to the at least one support element.

[0051] Particularly preferred is the elevation, the shape, the projection, the tab, the cup, the bridge, the strip, the stamp, the pin or the like formed integrally with the at least one supporting element.

[0052] Advantageously, the seal can have at least one through-opening for a fastening element in the at least one support element, and the at least one contact element can be arranged adjacent to the at least one through-opening.

[0053] The fastening element may preferably be a screw, a bolt, a rivet, or a comparable fastening element. By arranging the at least one contact element adjacent to the at least one through-hole, reliable contact can be ensured between the at least one contact element and the first and / or second object when the seal is positioned in a mounting position between the first and second objects and these are positively connected to each other by the fastening element.

[0054] Particularly preferably, the at least one contact element can be arranged essentially between two or more through-openings for fastening means.

[0055] If the first and second objects are connected to each other by two or more fastening means in a force-fit manner, the arrangement of at least one contact element between the through-openings can ensure particularly reliable contact between the first and / or second object by the at least one contact element.

[0056] A particularly preferred embodiment of the seal may provide that at least one contact element is provided on a section of the at least one support element which is assigned to the first object in a mounting position of the seal and / or at least one contact element is provided on a section of the at least one support element which is assigned to the second object in the mounting position of the seal.

[0057] In particular, the section of the at least one support element that is assigned to the first object in the assembly position of the seal, and the section of the at least one support element that is assigned to the second object in the assembly position of the seal, form opposite sides of the support element.

[0058] Preferably, the section of the at least one support element that is associated with the first object in the installation position of the seal corresponds to a top side of the support element or the seal (hereinafter referred to as the top side). Preferably, the section of the at least one support element that is associated with the second object in the installation position of the seal corresponds to a bottom side of the support element or the seal (hereinafter referred to as the bottom side).

[0059] In a further development of the seal, several contact elements can be provided spaced apart from each other on the section that is assigned to the first object in the assembly position of the seal, and / or several contact elements can be provided spaced apart from each other on the section that is assigned to the second object in the assembly position of the seal.

[0060] In particular, the multiple contact elements can be arranged spaced apart from each other along a direction of extension of the at least one support element.

[0061] Along the extension direction of at least one support element, the multiple contact elements can be aligned both in a common alignment and offset from each other.

[0062] With regard to the top and bottom surfaces, the multiple contact elements can preferably be arranged alternately on the top and bottom surfaces along the extension direction of the at least one support element.

[0063] Alternatively, the multiple contact elements can also be arranged in pairs in a corresponding arrangement on the top and bottom of the at least one support element.

[0064] The present invention further aims to provide a sealing arrangement that ensures a seal between a first fluid space and a second fluid space and enables a reliable electrical connection between a first and a second object.

[0065] This problem is solved by a sealing arrangement for sealing a first fluid space from a second fluid space or several fluid spaces, comprising a first object, a second object and a seal, preferably a seal according to one of the previously described embodiments, which can be arranged in a mounting position between the first object and the second object, wherein in the mounting position of the seal an electrically conductive contact of the first object and / or the second object is formed by at least one contact element projecting from a support element of the seal.

[0066] The first and / or second object may be provided with a coating, in particular with an electrically non-conductive coating.

[0067] The coating is a protective layer, which may preferably be formed by an electrochemical process, e.g. cathodic dip coating (e-coating) or the like.

[0068] Likewise, the coating can be designed as any other protective layer, e.g. as a plastic layer.

[0069] In order to enable the electrically conductive contact of the first object and / or the second object by the at least one contact element, at least one partial opening must be provided in the coating.

[0070] In the installation position of the seal, the at least one contact element is arranged corresponding to the at least one opening. In this way, the gap formed by the thickness of the coating can be bridged by the at least one contact element projecting from the support element, in order to electrically connect the first and / or second object via the at least one contact element.

[0071] A preferred application of the seal is in a housing comprising a seal according to one of the previously described embodiments. The advantages of the seal mentioned above are particularly evident in this application. Advantageously, such a housing could be a battery housing or a control housing, preferably for a motor vehicle.

[0072] The invention further relates to a housing, in particular a battery or control box, comprising a seal according to one of the previously described embodiments or a sealing arrangement according to the previously described embodiment. For the purposes of this description and the attached claims, a battery box is understood to mean in particular a housing for one or more batteries, especially batteries of an electric vehicle.

[0073] Within the scope of this description and the attached claims, a control box is understood to mean in particular a housing for one or more control components and / or one or more control devices.

[0074] The invention therefore has the further objective of providing a housing, in particular a battery or control box, in which a seal is mounted simply and safely and a first fluid chamber is reliably sealed from a second fluid chamber.

[0075] This problem is solved by a housing having the features of claim 10.

[0076] The housing includes a seal according to one of the previously described embodiments or a sealing arrangement according to the previously described embodiment.

[0077] The sealing element is arranged in a sealing manner between a first housing element, for example a housing base part, and a second housing element, for example a housing cover, and forms an electrically conductive connection between the first and the second housing element.

[0078] Further preferred features and / or advantages of the invention are the subject of the following description and the graphic representation of exemplary embodiments.

[0079] The drawings show:

[0080] Fig. 1: a schematic top view of a seal according to an embodiment as disclosed; Fig. 2: a partial sectional view of a seal arrangement in which the seal is arranged in a mounting position between two objects;

[0081] Fig. 3 shows a partial sectional view of another sealing arrangement, in which the

[0082] The seal is positioned between two objects in the mounting position.

[0083] Fig. 1 shows a schematic top view of a seal designated as a whole by 100 according to an embodiment as disclosed.

[0084] Such a seal 100 is provided in particular for sealing a first fluid chamber 102 from a second fluid chamber 104, for example in a battery or control box of a motor vehicle, in particular an electric motor vehicle.

[0085] The seal 100 is provided for arrangement between a first object 106, for example a housing cover of the battery or control box, and a second object 108, for example a housing base part of the battery or control box, as shown in more detail in Figs. 2 and 3.

[0086] The seal 100 comprises several support elements 110 that can be directly connected to one another or, as shown in Fig. 1, connected, forming a preferably dimensionally stable base body, and an elastic sealing element 112 arranged on the support elements 110.

[0087] The support elements 110 form the preferably dimensionally stable base body of the seal 100 and thereby provide a load-bearing function for the seal 100.

[0088] The seal 100 is therefore in particular a so-called carrier seal, preferably a metal elastomer seal and / or a plastic carrier seal.

[0089] The seal 100 comprises several through-openings 114 on the support elements 110, through which a fastening element 116, in particular a screw, a bolt, a rivet or the like, can be inserted to connect the first object 106 with the second object 108 (Figs. 2 and 3).

[0090] The support elements 110 each comprise, in particular, two connecting sections 118 for connecting the support elements 110 to one another. The support elements 110 are preferably connectable to one another in a main extension plane 120 (Figs. 2 and 3) of the seal 100, particularly in one assembly direction, for example by means of a plug-in connection.

[0091] The support elements 110 are in particular made of or comprise a metallic base material. The metallic base material is in particular steel or aluminium.

[0092] The support elements 110 are particularly preferably made, at least in sections, of an electrically conductive material.

[0093] Alternatively or additionally, the support elements 110 may be made at least partially from a plastic material or comprise a plastic material.

[0094] Preferably, the support elements 110 are manufactured entirely by punching and / or laser cutting from a metallic base material, for example from a sheet metal material.

[0095] Preferably, the connecting sections 118 of the support elements 110 are also produced by punching and / or laser cutting.

[0096] The elastic sealing element 112 provides a sealing function for the seal 100.

[0097] The elastic sealing element 112 preferably comprises an elastomeric material or is formed from an elastomeric material. The elastomeric material is, in particular, an ethylene acrylate rubber (AEM). Alternatively or additionally, the elastomeric material is an ethylene propylene diene monomer rubber (EPDM), an acrylate rubber (ACM), a fluororubber (FKM), a hydrogenated acrylonitrile butadiene rubber (HNBR), a liquid silicone, in particular liquid silicone rubber (LSR), or a silicone rubber (MVQ), in particular a vinyl methyl polysiloxane.

[0098] The elastic sealing element 112 is preferably injection-molded onto a carrier element 110 or onto the assembled carrier elements 110 during the manufacture of the seal 100 in an injection molding process. Preferably, the carrier elements 110 can be connected to each other by injection-molding the elastic sealing element 112 onto the carrier elements 110.

[0099] In other words, the support elements 110 can be joined together in the injection molding process by injecting the elastic sealing element 112, thus forming the seal 100.

[0100] The support elements 110 of the seal 100 are preferably ring-shaped, in particular ring-shaped and closed.

[0101] Since the support elements 110 are made in particular of an at least approximately inflexible or rigid material, preferably of a metallic base material, the load-bearing function of the seal 100 can be provided in particular by the support elements 110.

[0102] The seal 100 and / or the support elements 110 are preferably designed as flat surfaces.

[0103] The seal 100 and / or the support elements 110 extend in particular at least approximately along the main extension plane 120 indicated in Figs. 2 and 3 (image plane in Fig. 1).

[0104] To form the ring-shaped closed shape of the seal 100 shown in Fig. 1, the support elements 110 can be connected to each other, in particular in a puzzle-like manner and / or in a form-fitting manner.

[0105] A puzzle-like connection of the support elements 110 is achieved in particular by the connecting sections 118 of the support elements 110.

[0106] The elastic sealing element 112 is preferably injection-molded onto a circumferential inner edge 122 and a circumferential outer edge 124 of the support elements 110. Alternatively, it can also be provided that the elastic sealing element 112 is injection-molded only onto the inner edge 122 or only onto the outer edge 124 of the support elements 110.

[0107] Each of the support elements 110 has several contact elements 126 spaced apart from each other, which protrude from the support element 110.

[0108] The contact elements 126 are designed on the respective carrier element 110 in such a way that they form an electrically conductive contact with the first object 106 and / or the second object 108 when the seal 100 is arranged in a mounting position 128 shown in Figs. 2 and 3 between the first object 106 and the second object 108.

[0109] Due to the protruding design of the contact elements 126, these are designed in particular to bridge a gap 130 between the support element 110 and the first and / or second object 106, 108, which will be discussed in more detail below.

[0110] The contact elements 126 are arranged along a direction of extension of the support elements 110, and are preferably aligned in a common plane.

[0111] Likewise, the contact elements 126 can also be arranged in any arrangement or orientation along the extension direction of the support elements 110, for example in an offset arrangement.

[0112] In particular, several contact elements 126 are formed on one side of the carrier element 110, which in the assembly position 128 of the seal 100 is assigned to the first object 106 (hereinafter referred to as top 132) and several contact elements 126 are formed on one side of the carrier element 110, which in the assembly position 128 of the seal 100 is assigned to the second object 108 (hereinafter referred to as bottom 134).

[0113] In other words, several contact elements 126 are formed on the carrier element 110, projecting towards a top surface 132 of the carrier element 110, and several contact elements 126 projecting towards a bottom surface 134 of the carrier element 110.

[0114] With this design, the contact elements 126 can contact both the first object 106 and the second object 108 simultaneously.

[0115] It may preferably be provided that the contact elements 126 protrude alternately towards the top 132 and the bottom 134 of the support element 110 along the extension direction of the support element 110.

[0116] Alternatively, it can also be provided that two contact elements 126 are arranged in a corresponding arrangement, i.e. in pairs, on the top 132 and the bottom 134 of the support element 110.

[0117] Fig. 2 shows a partial sectional view of a sealing arrangement 136, in which the seal 100 is arranged in an exemplary assembly position 128 between the first object 106 and the second object 108.

[0118] The illustration clearly shows how the first object 106 and the second object 108 are connected to each other by the fastening means 116, the fastening means 116 being inserted through the through-opening 114 of the support element 110.

[0119] The contact elements 126 are preferably formed from the carrier element 110, as shown in Figs. 2 and 3.

[0120] For example, the contact elements 126 can be formed during a manufacturing step of the carrier element 110, for example by a forming process and / or a primary forming process, or by a separate manufacturing step to produce the carrier element 110 and / or form the contact elements 126.

[0121] Preferably, the contact elements 126 are integrally formed, i.e., as a single piece, with the carrier element 110. Due to the integral design of the contact elements 126 with the carrier element 110, they are in particular made of the same electrically conductive material as the carrier element 110, thereby ensuring the electrical conductivity of the contact elements 126 for contacting the first and / or second object 106, 108.

[0122] In an alternative or supplementary embodiment, it can also be provided that a contact element 126, several contact elements 126 or all contact elements 126 are molded into, molded onto or attached to the carrier element 110.

[0123] For example, at least one contact element 126 can be punched out and / or stamped into the carrier element 110. This allows the contact element 126 to be designed, for example, as a tab or as a differently shaped projection on the carrier element 110.

[0124] It can also be provided that at least one contact element 126 is attached or fastened to the carrier element 110 by welding, soldering, gluing or the like.

[0125] It is understood that the contact elements 126 can have any geometric design suitable for bridging the gap 130 between the support element 110 and the first object 106 and the second object 108.

[0126] For this purpose, the contact elements 126 can be designed, for example, as an arbitrarily shaped protrusion, a arbitrarily shaped projection, a arbitrarily shaped tab, an arbitrarily shaped cup, an arbitrarily shaped bridge, an arbitrarily shaped strip, an arbitrarily shaped stamp, an arbitrarily shaped pin, or the like, each of which is formed from, molded into, molded onto, or attached to the carrier element 110. In particular, the protrusion, the shape, the projection, the tab, the cup, the bridge, the strip, the stamp, the pin, or the like are integrally formed with the carrier element 110.

[0127] Likewise, one or more contact elements 110 can be provided on the support element 110, preferably as elongated elements, for example one or more sheets, webs, strips or the like, and in particular attached, for example welded on.

[0128] Preferably, the contact elements 126 have a height H with respect to a surface 138 of the support element 110 which is suitable for bridging a minimal gap 130 between the support element 110 and the first and / or second object 106, 108.

[0129] Such a gap 130 can be formed, for example, by the sealing element 112 having a greater thickness or height than the basic thickness or height of the support element 110, as shown in Fig. 2.

[0130] The gap 130 between the support element 110 and the first and / or second object 106, 108 may preferably have a width of at most about 0.5 mm, preferably at most about 0.2 mm, particularly preferably at most about 0.15 mm.

[0131] The term "approximately" throughout this description means a deviation from the specified value of + / -20%, preferably + / -10%, and most preferably + / -5%.

[0132] The height H of the contact elements 126 is specifically adapted to the width of the gap 130.

[0133] In other words, the contact elements 126 have a height H suitable to bridge the width of the gap 130 in order to contact the first object 106 and / or the second object 108.

[0134] Preferably, the contact elements 126 each have the same height H. For example, the contact elements 126 can have a height H relative to the surface 138 of the support element 110 of at least about 0.02 mm and at most about 0.5 mm.

[0135] Preferably, the contact elements 126 can have a height H relative to the surface 138 of the support element 110 of at least about 0.03 mm.

[0136] Particularly preferably, the contact elements 126 can have a height H with respect to the surface 138 of the support element 110 of at least about 0.05 mm.

[0137] Preferably, the contact elements 126 can have a height H relative to the surface 138 of the support element 110 of at most about 0.3 mm.

[0138] Particularly preferably, the contact elements 126 can have a height H with respect to the surface 138 of the support element 110 of at most about 0.2 mm.

[0139] In particular, the contact elements 126 can have a height H with respect to the surface 138 of the support element 110 of at most about 0.15 mm.

[0140] Each of the contact elements 110 provides for only partial contact with the first object 106 and / or the second object 108.

[0141] In particular, the contact elements 110 each form a contact surface 140 pointing away from the carrier element 110, which is designed to contact the first object 106 and / or the second object 108.

[0142] The contact elements 110 can form a contact surface 140 which has a round, oval, angular, elongated or any other shaped planar extent.

[0143] The contact surface 140 of the contact element 126 can, for example, have a planar extent of at most approximately 5 cm. 2 , preferably no more than about 2 cm 2 , especially preferably at most about 1 cm2 , exhibit. It can also be provided that one or more contact elements 110 form an elongated contact surface 140 extending at least sectionally along the support element 110.

[0144] It can also be provided that the contact elements 110 for contacting the first object 106 and / or the second object 108 each form a contact point pointing away from the support element 110.

[0145] Fig. 3 shows a partial sectional view of a further sealing arrangement 136, in which the seal 100 is arranged in the mounting position 128 between the first and second object 106, 108, wherein the two objects 106, 108 are provided with a coating 142.

[0146] It can also be provided that only one of the objects 106, 108 is provided with such a coating 142.

[0147] The coating 142 can be any protective layer provided on the first and / or second object 106, 108.

[0148] In particular, the coating is an electrically non-conductive, i.e., electrically insulating, coating 142.

[0149] Preferably, the coating 142 can be a protective layer formed by an electrochemical process.

[0150] In particular, coating 142 may be a cathodic dip coating (e-coating).

[0151] Likewise, coating 142 can be a plastic layer or any other protective layer.

[0152] The coating 142 can have a layer thickness of at most approximately 0.5 mm, preferably at most approximately 0.2 mm, particularly preferably at most approximately 0.10 mm, and especially approximately 0.05 mm. To form contact between the contact elements 126 and the electrically conductive surface 138 of the first and / or second object 106, 108, several openings 144 are provided in the coating 142.

[0153] In particular, a number of perforations 144 corresponding to the number of contact elements 126 are formed in the coating 142.

[0154] These openings 144 can be formed, for example, during a coating process, for example by masking the object 106, 108 to be coated in certain areas, or by subsequently processing the coating 142, for example by laser processing in certain areas.

[0155] The openings 144 in the coating 142 are formed correspondingly, i.e. at a corresponding distance and / or in a corresponding orientation, to the contact elements 126 on the carrier element 110.

[0156] In the assembly position 128 of the seal 100, the contact elements 126 projecting from the carrier element 110 are each arranged in one of the corresponding openings 144 in the coating 142.

[0157] In this way, the contact elements 126 serve to bridge the gap 130 formed by the coating 142 between the carrier element 110 and the first and / or second object 106, 108, in order to form the electrically conductive contact to the surface 138 of the first and / or second object 106, 108.

[0158] The seal 100 as disclosed thus makes it possible to form a seal between the two objects 106, 108 and at the same time to form an electrical connection between the support element 110 of the seal 100 and the first and / or second object 106, 108, which are preferably provided with the electrically non-conductive coating 142.

[0159] In this way, for a housing consisting of at least two housing components (first and second objects 106, 108), it can be ensured that, in addition to sealing the housing components, reliable electromagnetic compatibility is also guaranteed, so that electromagnetic

[0160] Radiation remains inside the housing and is not emitted to the outside.
