초록 ▼

The present invention relates to an electric contact arrangement (1) comprising: a housing (2) having a recess (3) that penetrates the housing (2) in an axial direction (7); a sleeve (4) which is inserted into the recess (3) and which has an axial sealing surface (8) inside the housing (2) and two projections (10) outside the housing (2) which run perpendicularly to the axial direction (7); a contact pin (5) which is fixed in the sleeve (4) and which extends through the sleeve (4); an attachment element (6) which is designed to lie on the housing (2) and to be slid under the projections (10); and wedge shaped surfaces (13) between the sleeve (4) and the attachment element (6) and/or between the housing (2) and the attachment element (6) such that the sealing surface (8) can be drawn against the housing (2) from the inside by means of sliding the attachment element (6) under the projections (10).

대표청구항 ▼

1. An electrical contact arrangement (1) comprising a housing (2) having a cutout (3) that penetrates the housing (2) in an axial direction (7),a bushing (4) inserted into the cutout (3), said bushing (4)having an axial sealing surface (8) in an interior of the housing (2) andhaving two ledges (10) extending perpendicularly to the axial direction (7) outside the housing (2),a contact pin (5) which is arranged fixedly in the bushing (4) and projects through the bushing (4),a fastening element (6) which is configured to rest on the housing (2) and to be introduced under the ledges (10), andwedge-shaped surfaces (13) between the bushing (4) and the fastening element (6) and/or between the housing (2) and the fastening element (6), such that, as a result of the fastening element (6) being introduced under the ledges (10), the sealing surface (8) is able to be drawn against the housing (2) from the inside. 2. The contact arrangement (1) as claimed in claim 1, characterized in that the fastening element (6) is configured in a fork-shaped manner by comprising two mutually connected, parallel fingers (11) for introduction under the ledges (10). 3. The contact arrangement (1) as claimed in claim 2, characterized in that the wedge-shaped surfaces (13) are formed on the fingers (11) and on the ledges (10). 4. The contact arrangement (1) as claimed in claim 1, characterized in that the contact pin (5) is arranged in the bushing (4) in a rotation-proof manner by way of a form fit. 5. The contact arrangement (1) as claimed in claim 1, characterized in that the bushing (4) is produced from plastics material and the contact pin (5) is encapsulated by the plastics material of the bushing (4). 6. The contact arrangement (1) as claimed in claim 1, characterized in that the fastening element (6) rests on the housing (2) in a rotation-proof manner by way of a form fit. 7. The contact arrangement (1) as claimed in claim 1, characterized in that an inclination of the wedge-shaped surfaces (13) provides a self-locking hold of the fastening element (6). 8. The contact arrangement (1) as claimed in claim 1, characterized by further comprising a latching connection (17) between the fastening element (6) and the housing (2) for fixing the introduced fastening element (6). 9. The contact arrangement (1) as claimed in claim 1, characterized in that an annular seal (9) is arranged on the sealing surface (8). 10. An arrangement for a vehicle, comprising at least one electrical contact arrangement (1) as claimed in claim 1, wherein a control unit, power electronics, an energy store and/or an electric machine is/are arranged in the housing (2). 11. The contact arrangement (1) as claimed in claim 1, wherein the ledges (10) extend perpendicularly to the axial direction (7) in grooves outside the housing (2). 12. The contact arrangement (1) as claimed in claim 11, characterized in that the fastening element (6) is configured in a fork-shaped manner by comprising two mutually connected, parallel fingers (11) for introduction under the ledges (10). 13. The contact arrangement (1) as claimed in claim 12, characterized in that the wedge-shaped surfaces (13) are formed on the fingers (11) and on the ledges (10) in the grooves.
