[0002] title electrical

[0003] The invention relates to a contacting arrangement for two spatially separated electrical components. The present invention also relates to a device arrangement comprising two spatially separated electrical components and an intermediate component arranged between the two spatially separated electrical components. In this case, the two spatially separated electrical components are electrically connected to one another via such a contacting arrangement.

[0004] It is known from the prior art to make direct contact between a control unit and an electric motor. In the event that direct electrical contact is not possible between the electric motor and the control unit, for example because a housing is placed between the electric motor and the control unit, two different contacting arrangements are known. In one possible contacting arrangement, at least one female contact is arranged on the electric motor and at least one extended male contact is arranged on the control unit in order to bridge the distance between the electric motor and the control unit. In an alternative contacting arrangement, at least one extended male contact is arranged on the electric motor and at least one female contact is arranged on the control unit in order to bridge the distance between the electric motor and the control unit.Due to the required spacing of the male contacts and the female contacts from each other, appropriate installation space must be provided in the housing in both radial directions for these known contact arrangements.

[0005] Disclosure of the Invention The contacting arrangement for two spatially separated electrical components with the features of independent patent claim 1 and the corresponding device arrangement with the features of independent patent claim 11 each have the advantage that an intermediate contact assembly is arranged between a first contact assembly and a second contact assembly, so that first contact elements of the first contact assembly are no longer directly contacted with second contact elements of the second contact assembly. The intermediate contact assembly enables the first contact elements of the first contact assembly to be arranged as compactly and space-savingly as possible. In addition, the second contact elements of the second contact assembly can also be arranged compactly and space-savingly.A further advantage is a significantly lower wall thickness, which must be maintained in an intermediate component arranged between the first contact assembly and the second contact assembly for contacting.

[0006] Embodiments of the present invention provide a contacting arrangement for two spatially separated electrical components, with a first contact assembly of a first of the electrical components, which comprises at least two space-savingly arranged first contact elements, and a second contact assembly of a second of the electrical components, which comprises at least two second contact elements. An intermediate contact assembly, which comprises at least two third contact elements and at least two fourth contact elements, is arranged between the first contact assembly and the second contact assembly. The arrangement of the at least two third contact elements, which are electrically conductively connected to the at least two fourth contact elements via at least two connecting elements, corresponds to the space-saving arrangement of the at least two first contact elements.The at least two first contact elements are electrically conductively connected to the at least two third contact elements via at least two extension elements designed to bridge a distance between the first contact assembly and the intermediate contact assembly. The second contact assembly and the intermediate contact assembly are detachably connected to one another such that the at least two second contact elements of the second contact assembly are electrically conductively connected to the at least two fourth contact elements of the intermediate contact assembly.

[0007] In addition, a device arrangement with two spatially separated electrical components and an intermediate component is proposed, which is arranged between the two spatially separated electrical components. In this case, the two spatially separated electrical components are electrically connected to one another via such a contacting arrangement. A first contact assembly with at least two first contact elements is arranged on a surface of a first of the electrical components facing the intermediate component. A second contact assembly with at least two second contact elements is arranged on a surface of a second of the electrical components facing the intermediate component. An intermediate contact assembly with at least two third contact elements and at least two fourth contact elements is arranged on a surface of the intermediate component facing the second contact assembly.

[0008] The measures and further developments listed in the dependent claims enable advantageous improvements to the device specified in independent patent claim 1 and the method specified in independent patent claim 1.

[0009] It is particularly advantageous that the first contact assembly can comprise two first contact elements arranged in an L-shape or opposite one another to save space. Alternatively, the first contact assembly can comprise three first contact elements arranged in a U-shape to save space. In a further alternative embodiment, the first contact assembly can comprise four first contact elements arranged in an O-shape to save space. The aforementioned arrangements enable a particularly compact design of the first contact assembly with a similar space requirement but a different number of first contact elements. Of course, a different number of contact elements and / or a different suitable arrangement of the contact elements are also possible.In an advantageous embodiment of the contacting arrangement, the at least two first contact elements can be designed as male contacts and formed integrally with the at least two extension elements. Alternatively, the at least two first contact elements can be designed as male contacts and integrally connected to the at least two extension elements. In addition, the at least two third contact elements can be designed as male contacts and integrally connected to the at least two extension elements. A male contact is understood here to be an electrical contact which is designed, for example, as a surface or pin protruding from a contact carrier. The integral connection can be designed, for example, as a soldered or welded connection.

[0010] In a further advantageous embodiment of the contacting arrangement, the at least two extension elements can be designed, for example, as sheet metal strips or as pieces of wire. This enables cost-effective production of the extension elements.

[0011] In a further advantageous embodiment of the contacting arrangement, the at least two fourth contact elements of the intermediate contact assembly and the at least two second contact elements of the second contact assembly can each be arranged next to one another in a contact housing. The two contact housings can be connected to one another via a detachable plug connection. This enables a particularly compact design of the second contact assembly and the intermediate contact assembly, since the second contact elements and the fourth contact elements can be positioned more compactly and thus in a more space-saving manner. For example, the at least two second contact elements of the second contact assembly can be designed as male contacts, which interact in an electrically conductive manner with the at least two fourth contact elements of the intermediate contact assembly, which can be designed as female contacts.Alternatively, the at least two second contact elements of the second contact assembly can be designed as female contacts, which electrically interact with the at least two fourth contact elements of the intermediate contact assembly, which can be designed as male contacts. A female contact is understood here to mean an electrical contact that is designed, for example, as a plug receptacle or socket.

[0012] In a further advantageous embodiment of the contacting arrangement, the at least two connecting elements of the intermediate contact assembly can be designed as stranded wires or as wire clips. This enables cost-effective and simple production of the intermediate contact assembly.

[0013] In an advantageous embodiment of the device arrangement, the first electrical component can be designed as an electric motor. The second electrical component can be designed as a control unit. The intermediate component can be designed as a housing to which the two spatially separated electrical components are attached on opposite surfaces.

[0014] In a further advantageous embodiment of the device arrangement, the at least two extension elements, which are designed to bridge a distance between the first contact assembly and the intermediate contact assembly, can be guided in a wall of the intermediate component designed as a housing. Due to the compact and thus space-saving arrangement of the first contact elements of the first contact assembly, less installation space is required for the at least two extension elements in the intermediate component designed as a housing, so that the wall of the intermediate component designed as a housing can be made thinner.
