Description

The present invention relates to a contact element for arrangement between two objects. The invention also relates to a sealing arrangement and a housing, in particular a battery housing or a control housing.

Various seals are known in the art for sealing fluid spaces between two components. Elastomeric seals, in particular, are used, for example, to seal housing elements from one another and to protect the interior of the housing from moisture and dirt. Housings made of metallic material are typically used for shielding electromagnetic radiation, and the use of such an elastomeric seal interrupts the electrical conductivity between the housing elements. This can impair the shielding of electromagnetic radiation.

The present invention is based on the objective of providing a contact element that ensures reliable electrically conductive contact between objects and has a simple and cost-effective design.

This problem is solved by a contact element for arrangement between a first object and a second object, comprising a base body with a first contact section and at least one second contact section, which, when the contact element is arranged between the first and second object, form an electrically conductive contact between the first object and/or the second object, and with at least one connecting section that connects the first contact section and the at least one second contact section, wherein the at least one connecting section has or forms an elastic area through which the contact sections are movable relative to each other.

Such a contact element can be used in particular for the electrically conductive contacting of the first and second objects if, at the same time, the first and second objects are sealed fluid-tight to each other by a sealing element that has an electrically insulating effect.

To arrange the contact element between the first and second object, a recess for the contact element can preferably be formed on the first object and/or on the second object.

The depression can preferably be formed along a longitudinal extension of the first and/or second object.

In the area of the depression, a gap is formed between the first object and the second object, which can be bridged for electrical contact between the two objects by the contact element.

For this purpose, the contact element can advantageously have a greater height than the distance formed in the area of the recess between the first object and the second object.

Preferably, the contact element consists at least partially of an electrically conductive material.

In particular, the contact element is made of or comprises a metallic material, wherein the metallic material is in particular steel, stainless steel or aluminium.

Likewise, the contact element may be made of or comprise a plastic material, at least in part.

The contact element is specifically designed to extend at least section by section along the first and second objects in a longitudinal dimension.

It can be advantageous if the contact element extends at least approximately along a plane, in particular along a principal extension plane.

The connecting section connecting the contact sections can preferably form a spring area, i.e., an area of the base body that has elastic, in particular spring-elastic, properties, so that the contact sections are movable relative to each other, in particular spring-elastic, when arranged between the first and second object.

In this way, the contact element between the two objects can be clamped or secured to ensure reliable contact between the first and/or second object.

Advantageously, the contact element can also be formed from at least two base bodies, which are preferably stacked on top of each other and coupled together. For example, the contact element can be composed of two, three, four or more base bodies.

Such a contact element comprising several base bodies, which are preferably stacked on top of each other, can form a multi-layered contact element, for example a two-layered, three-layered, four-layered or more than four-layered contact element.

Preferably, adjacent base bodies of such a multilayer contact element can be designed to be mirror-symmetrical to each other.

Such a multi-layered contact element makes it possible to bridge larger gap widths, especially gap widths multiples of the height of the contact element, between the first object and the second object.

Preferably, the at least two base bodies of the contact element can be joined together by a material bond and/or a form-fit bond. For example, they can be welded, soldered, crimped, glued, or the like.

A further development of the contact element can also provide that the first contact section, the at least one second contact section and the at least one connecting section form an integral basic body.

In other words, the first contact section, the at least one second contact section and the at least one connecting section can preferably be formed in one piece.

Due to the integral design of the base body, the first contact section, the at least one second contact section and the at least one connecting section can be made of the same material, in particular an electrically conductive one.

A particularly advantageous embodiment of the contact element can provide that the base body is ring-shaped.

In particular, the base body can be designed to be closed in a ring shape.

One embodiment may provide that the base body is composed of several base body segments which together form the closed ring shape of the contact element.

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

In a further development of the contact element, the first contact section and/or at least one second contact section can each form an edge region of the base body extending along a longitudinal extent of the base body.

In particular, if the base body of the contact element is designed in the ring shape, the edge areas of the base body formed by the contact sections can be designed as, preferably completely, circumferential edge areas.

Advantageously, one of the contact sections forms an outer circumferential edge of the base body and the other contact section forms an inner circumferential edge of the base body.

Preferably, the contact sections form planar edge areas of the base body, through which a contact surface pointing away from the contact element is formed.

Preferably, the contact surfaces of the contact sections are designed to point in opposite directions to the first object and the second object.

In a mounting configuration of the contact element between the first object and the second object, the contact surfaces formed by the contact sections can lie against them.

Preferably, at least one contact section, in particular both contact sections, has a width transverse to the longitudinal extent of the base body that is at most 2.5 mm, preferably at most 1.5 mm, more preferably at most 1.25 mm, and/or at least 0.5 mm, more preferably at least 0.75 mm.

For example, the width of at least one contact section, in particular of both contact sections, transverse to the longitudinal extent of the base body can be approximately 1 mm, +/- 20%, preferably +/- 10%.

Preferably, the width of the contact sections corresponds to a distance between the outer circumferential edge of the base body and the at least one connecting section, or to a distance between the inner circumferential edge of the base body and the at least one connecting section.

Consequently, the width of the contact sections can be determined by the width of the outer or inner edge. area of the base body transverse to the longitudinal extent of the base body.

Such a width of contact sections ensures reliable contact between the first and second objects by their respective contact sections and, in particular, prevents one of the contact sections from contacting the opposite object by bending while clamped.

Such a width of contact sections ensures that the first object and the second object are contacted in the transition area or near the transition area between the respective contact section and the at least one connecting section.

Another advantageous embodiment of the contact element can provide that the base body is formed as a molded part, a bent part, a deep-drawn part or the like from a planar extending element.

In particular, the contact element can be formed by a bending process, a forming process and/or a primary forming process.

Preferably, the base body can be formed entirely from a planar base body material, for example from a sheet metal material, by punching and/or laser cutting, and subsequently the contact element can be manufactured as a shaped part, a bent part, a deep-drawn part or the like from the metallic base body material.

In a preferred embodiment of the contact element, the base body can have a material thickness of at most about 0.5 mm, preferably at most about 0.3 mm, and/or at least about 0.1 mm.

For example, the base body of the contact element can have a material thickness of approximately 0.2 mm.

In a further development of the contact element, the first contact section and at least one second contact section can be arranged at least partially in different planes spaced apart from each other.

It may preferably be provided that the contact sections in the different spaced-apart planes are arranged in a stepped, offset arrangement.

In particular, the connecting section is designed in such a way that the first contact section and the at least one second contact section are connected to each other in a step-like offset arrangement by the connecting section.

Preferably, the stepped offset between the contact sections can be achieved by forming the connecting section at an inclined angle, i.e. in an oblique orientation, to the main extension plane of the contact element.

The connecting section can therefore form an inclined or slanted section of the base body between the contact sections.

Preferably, the connecting section can be aligned at an angle between 0° and 90°, preferably between about 20° and about 70°, to the main extension plane of the contact element.

In particular, the connecting section can be aligned at an angle of approximately 45°, +/- 20°, preferably +/- 10°, to the main extension plane of the contact element.

The offset between the contact elements and/or the height of the contact element can be defined by the length and/or the angle of inclination of the connecting section.

A preferred further development of the contact element can also provide that a distance between the planes in which the contact sections are arranged is equal to or greater than a distance of an offset of the contact sections to each other.

Preferably, the distance between the planes in which the contact sections are arranged can be at most about 1.5 mm, preferably at most about 1.2 mm.

Preferably, the height of the contact element can be greater than the offset between the contact sections.

For example, the ratio between the height of the contact element and the offset between the contact sections can be between 0.7 and 1.5, preferably between 1.0 and 1.3.

Preferably, the ratio between the height of the contact element and the offset between the contact sections can be at least approximately 1.2:1.

Preferably, the height of the contact element can be greater than the material thickness of the base body.

For example, the ratio between the height of the contact element and the material thickness of the base body can be between 3 and 8, preferably between 4 and 7.

Preferably, the ratio between the height of the contact element and the material thickness of the base body can be at least approximately 4:1.

Preferably, the offset between the contact sections can be greater than the material thickness of the base body.

For example, the ratio between the offset between the contact sections and the material thickness of the base body can be between 4 and 15, preferably between 5 and 10.

Preferably, the ratio between the offset between the contact sections and the material thickness of the base body can be at least approximately 5:1.

For example, the distance between the planes in which the contact sections are arranged can be approximately 1.1 mm.

The offset between the contact sections can preferably be less than about 5 mm, more preferably less than about 3 mm, more preferably less than about 2 mm, and more preferably less than about 1.5 mm.

For example, the offset between the contact sections can be approximately 1.0 mm.

Preferably, the ratio between the width of at least one of the contact sections and the height of the contact element can be at most 2.0, preferably at most 1.5, more preferably at most 1.0, more preferably at most 0.5, and/or at least 0.1, preferably at least 0.2.

A ratio between the width of at least one of the contact sections and the material thickness of the base body can preferably be between 2.5 and 5, in particular less than 4.

Furthermore, the invention is based on the objective of providing a sealing arrangement that enables a safe sealing of a first fluid chamber from a second fluid chamber and ensures a reliable electrically conductive connection between objects.

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, at least one sealing element and at least one contact element according to one of the previously described embodiments, wherein in a mounting configuration of the contact element and the sealing element between the first object and the second object the first contact section and the at least one second contact section of the contact element form an electrically conductive contact of the first object and/or the second object, and the sealing element seals the first fluid space from the second fluid space.

Such a sealing arrangement 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, to each other by means of the elastic sealing element and at the same time to form an electrically conductive contact between the first object and/or second object by means of the contact element, for example in a battery or control box of a motor vehicle, in particular an electric motor vehicle.

Preferably, the at least one contact element and the at least one sealing element are designed as individual components, i.e., separate components.

Likewise, the at least one contact element and the at least one sealing element can be configured in a coupled configuration; for example, the at least one sealing element can be arranged or attached to the at least one contact element.

For example, at least one sealing element can be partially injection-molded onto the contact element using an injection molding process or partially printed on using a screen printing process.

In the context of this description and the attached claims, injection molding is understood in particular to mean joining the at least one sealing element with the at least one contact element, in which the at least one sealing element is produced in an injection molding process such that it is attached to the at least one contact element in certain areas.

A preferred application of the contact element or sealing arrangement described above is, in particular, in a housing comprising a contact element or a seal. arrangement according to one of the previously described embodiments. The advantages of the contact element or sealing arrangement mentioned above are particularly evident in this case. Advantageously, such a housing can be a battery housing, a motor housing, a control housing, or an inverter housing, preferably for a motor vehicle.

The invention further relates to a housing, particularly for electrical and/or electrotechnical applications, for example in a vehicle, especially as a component of the powertrain. The housing is, in particular, a battery, motor, control unit, or inverter housing. The housing comprises a contact element according to one of the previously described embodiments or a sealing arrangement according to the previously described embodiment.

The contact element is arranged in an electrically contacting 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.

The sealing element of the sealing arrangement is arranged in a sealing manner, in particular, between the first housing element, for example the housing base, and the second housing element, for example the housing cover, and forms a fluid-tight seal between a first fluid space and a second fluid space.

1 shows a perspective sectional view of a sealing arrangement designated as a whole by 100 according to an embodiment as disclosed.

Such a sealing arrangement 100 is provided in particular for sealing a first fluid chamber 102 from a second fluid chamber 104, for example in a battery or motor or control or inverter housing of a motor vehicle, in particular an electric motor vehicle.

The sealing arrangement 100 is intended for arrangement between a first object 106 and a second object 108, for example a housing cover and a housing base part of the battery or motor or control or inverter housing.

The sealing arrangement 100 comprises at least one contact element 110 and at least one elastic sealing element 112.

Preferably, the contact element 110 and the elastic sealing element 112 are provided separately from each other, as shown in 1 depicted.

The elastic sealing element 112 provides a sealing function for the sealing arrangement 100. For this purpose, the sealing element 112 can be positioned closer to an outer surface than the contact element 110, for example in the case of a housing to be sealed.

In particular, the elastic sealing element 112 is arranged on a sealing section 114 between the first object 106 and the second object 108 and seals the first fluid chamber 102 and the second fluid chamber 104 in a fluid-tight manner.

Preferably, the elastic sealing element 112 is designed in an annular form, in particular in an annularly closed form.

Advantageously, the elastic sealing element 112 can be provided as a liquid seal on the sealing section 114 of the first and/or second object 106, 108 before the first and second object 106, 108 are assembled.

Alternatively, it can also be provided that the elastic sealing element 112 is arranged or attached to the contact element 110, for example the sealing element 112 can be partially injection molded onto the contact element 110 by an injection molding process or partially printed on by a screen printing process.

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.

The contact element 110 is intended for arrangement between the first object 106 and the second object 108 and forms an electrically conductive contact between the first object 106 and the second object 108.

Preferably, the contact element 110 is provided to be arranged in a recess 116 formed on the first object 106 and/or on the second object 108, which extends along the first and/or second object 106, 108.

In the area of depression 116, a gap is formed between the first object 106 and the second object 108.

In particular, the gap between the first object 106 and the second object 108 in the area of the recess 116 is larger than the distance between the first object 106 and the second object 108 in the area of the sealing section 114 in which the elastic sealing element 112 is arranged.

The contact element 110 serves to bridge this gap between the first object 106 and the second object 108 in order to form the electrically conductive contact between the first and second object 106, 108.

The contact element 110 consists in particular at least in sections of an electrically conductive material.

Preferably, the contact element 110 is made of or comprises a metallic material. The metallic material is, in particular, steel or aluminum.

Alternatively or additionally, the contact element 110 may be made of or comprise a plastic material, at least in sections.

Preferably, the contact element 110 is formed entirely by punching and/or laser cutting from a metallic base material, for example from a sheet metal material.

After punching and/or laser cutting, the contact element 110 can preferably be manufactured as a shaped part, a bent part, a deep-drawn part or the like from the metallic base body material, for example from sheet metal material.

In other words, the contact element 110 is preferably formed from a planar base material by a bending process, a forming process and/or a primary forming process.

Preferably, the contact element 110 is designed in such a way that it has a ring-shaped, in particular a ring-shaped closed, form, as shown in 2 is shown.

A ring shape is understood to mean that the contact element 110 has both a rectangular shape, as in 2 shown, as well as being able to have a polygonal shape, round shape, oval shape or any other freeform shape.

The contact element 110 is formed by a base body 118, which has a first contact section 120 and a second contact section 122.

Contact sections 120 and 122 are located in a 1 The illustrated mounting configuration 124 is applied to the first object 106 and the second object 108 when the contact element 110 in the mounting configuration 124 is inserted in the recess 116 on the first object 106 and/or on the second object 108, whereby the electrically conductive contact between the first object 106 and the second object 108 is formed via the contact element 110.

In particular, the contact sections 120, 122 each form a contact surface pointing away from the contact element 110, which in the assembly configuration 124 of the contact element 110 rests against the first object 106 and the second object 108.

The first contact section 120 and the second contact section 122 are connected to each other by a connecting section 126 of the base body 118.

In particular, the first contact section 120, the second contact section 122 and the connecting section 126, which connects the first contact section 120 and the second contact section 122, form an integral basic body 118.

In other words, the first contact section 120, the second contact section 122 and the connecting section 126 together form a single-piece basic body 118.

The base body 118 preferably has a material thickness of at most about 0.5 mm, preferably at most about 0.3 mm, and at least about 0.1 mm.

For example, the base body 118 can have a material thickness of approximately 0.2 mm.

3 Figure 1 shows a schematic sectional view of the contact element 110 in the assembly configuration 124, which illustrates the arrangement of the first contact section 120, the second contact section 122 and the connecting section 126 between the first and the second object 106, 108.

The contact element 110 extends essentially with respect to a principal extension plane 128, which is in 3 runs perpendicular to the image plane and in 2 lies in the image plane.

The first contact section 120 and the second contact section 122 form planar boundary areas of the base body 118, which extend substantially apart, preferably parallel, to the main extension plane 128.

The first contact section 120 and/or the second contact section 122 have a width transverse to the longitudinal extent of the base body 118 which is at most about 2.5 mm, preferably at most about 1.5 mm, more preferably at most about 1.25 mm, and/or at least about 0.5 mm, more preferably at least about 0.75 mm.

For example, the width of the contact sections 120, 122 transverse to the longitudinal extent of the base body 118 can be approximately 1 mm, +/- 20%, preferably +/- 10%.

The width of the respective contact section 120, 122 corresponds to a distance between an outer circumference of the base body 118 and the connecting section 126 or a distance between an inner circumference of the base body 118 and the connecting section 126.

In particular, the first contact section 120 and the second contact section 122 are arranged, at least in some areas, in different planes spaced apart from each other. That is, the first contact section 120 and the second contact section 122 are arranged, at least in some areas, in planes that are spaced 130 apart from each other.

The distance 130 between the planes in which the contact sections 120, 122 are arranged, i.e. the distance 130 between the contact sections 120, 122 in the vertical direction, is at most about 1.5 mm, preferably at most about 1.2 mm.

For example, the distance 130 between the planes in which the contact sections 120, 122 are arranged can be approximately 1.1 mm.

The term "approximately" means a deviation of +/- 20%, preferably +/- 10%, and particularly preferably +/- 5% from the stated absolute value.

In particular, the distance 130 between the planes in which the contact sections 120, 122 are arranged corresponds to a height H of the contact element 110 in the vertical direction.

The height H of the contact element 110 can therefore be at most about 1.5 mm, preferably at most about 1.2 mm.

For example, the height H of the contact element 110 can be approximately 1.1 mm.

In this way, the contact element 110 can bridge the gap formed in the area of the recess 116 between the first object 106 and the second object 108 in order to form the electrically conductive contact between the objects 106, 108.

In other words, the contact element 110 has a height H suitable to bridge the width of the gap between the first object 106 and the second object 108 in the area of the recess 116 in order to electrically contact the first object 106 and the second object 108.

The gap between the first object 106 and the second object 108 in the area of the recess 116 can therefore preferably have a width of at most about 1.5 mm, preferably at most about 1.2 mm.

In an embodiment of the contact element 110 not shown in detail, the contact element 110 can be composed of several base bodies 118, which also allows larger gap widths between the first object 106 and the second object 108 to be bridged.

Preferably, several base bodies 118, for example two, three, four or more base bodies 118, can be coupled together to form a multi-layered contact element 110. In particular, several base bodies 118 can be stacked on top of each other, with adjacent base bodies 118 preferably being mirror-symmetrical to each other. This allows multiple gap widths between the first object 106 and the second object 108 to be bridged with respect to the height of a base body 118.

The multiple base bodies 118 can be connected to each other by material bonding and/or form bonding, for example by welding, soldering, crimping, gluing or the like.

The first contact section 120 and the second contact section 122 each form an edge region of the base body 118 extending along the contact element 110.

In particular, the first contact section 120 and the second contact section 122 form circumferential edge areas of the ring-shaped base body 118.

For example, the first contact section 120 forms an outer circumferential edge 132 of the base body 118 and the second contact section 122 forms an inner circumferential edge 134 of the base body 118.

It is understood that the first contact section 120 can form the inner circumferential edge 134 of the base body 118 and the second contact section 122 can form the outer circumferential edge 132 of the base body 118.

The contact sections 120, 122 are preferably arranged in a stepped arrangement relative to each other, as is particularly the case in 3 is shown.

For this purpose, the connecting section 126, which connects the contact sections 120, 122, has an inclined course with respect to the main extension plane 128.

Preferably, the connecting section 126 can be inclined at an angle of inclination 136 between 0° and 90° to the main extension plane 128, preferably between about 20° and about 70°.

In particular, the connecting section 126 can be inclined at an angle 136 of approximately 45°, +/- 20°, preferably +/- 10°, to the main extension plane 128.

By arranging the connecting section 126 at an angle of inclination 136, the contact sections 120, 122 are arranged in a step-like offset V to each other.

In particular, it is provided that the offset V between the contact sections 120, 122 is equal to or smaller than the height H of the contact element 110.

In other words, the distance 130 between the planes in which the contact sections 120, 122 are arranged is equal to or greater than the offset V between the contact sections 120, 122.

In particular, the offset V between the contact sections 120, 122 is smaller than about 5 mm, preferably smaller than about 3 mm, particularly preferably smaller than about 2 mm, and especially smaller than about 1.5 mm.

For example, the offset V between the contact sections 120, 122 can be approximately 1.0 mm.

The inclined arrangement of the connecting section 126 forms a region of the base body 118 which has elastic, in particular spring-elastic, properties.

Preferably, the connecting section 126 can form a spring area, i.e., an elastic, preferably spring-elastic, section of the base body 118, through which the contact sections 120, 122 can be moved relative to each other.

This allows the contact sections 120, 122 in the assembly configuration 124 of the contact element 110 to be moved towards each other by the first object 106 and the second object 108, i.e., the contact sections 120, 122 are moved by an assembly force between the objects 106, 108 in the direction of the 3 The arrows drawn to the main extension plane 128 were moved, and onto In this way, the contact element 110 is clamped between the objects 106, 108.

Due to the elastic property of the connecting section 126, the contact element 110 can thus be clamped between the first object 106 and the second object 108, thereby ensuring the electrically conductive contact between the first object 106 and the second object 108 by means of the contact element 110.

The contact element 110 can therefore form a spring element.

The angle of inclination 136 of the connecting section 126 can change, in particular decrease, by clamping the contact element 110 between the first object 106 and the second object 108, thereby generating a spring force by which the contact element 110 is clamped between the first and second object 106, 108.
