Abstract

The invention relates to a device for power contacting having a contact-pin receptacle and at least one electrical connector where the contact-pin receptacle is integrally formed from two partial contacts that are arranged one over the other at a distance from each other and can be moved relative to each other. Each partial contact has an opening with contact arms protruding into the opening, and the two openings are arranged coaxial to each other. The contact arms of one opening are bent toward the contact arms of the other opening in such a way that the contact arms mesh with each other.

Claims

1. Device for power contacting (1), comprising a contact pin holder (2) and at least one electrical connection (3), wherein the contact pin holder (2) is integrally formed from two partial contacts (4, 5) which are arranged so as to be spaced apart, one on top of the other, and which can move relative to one another, wherein each partial contact (4, 5) comprises an opening (6, 7) having contact arms (8, 9) which project into the opening (6, 7), wherein the two openings (6, 7) are coaxial with one another, wherein the contact arms (8, 9) of one opening (6, 7) are bent towards the contact arms (8, 9) of the other opening so as to mesh with one another, wherein the contact arms (8, 9), starting from an opening edge (10), firstly comprise a portion (11) that extends radially, wherein the portion (11) that extends radially is followed by a portion (12) that extends axially characterized in that the partial contacts (4, 5) are moveable relative to each other, wherein the partial contacts (4, 5) are interconnected at a base (20) with a distance A to each other, wherein the two partial contacts (4, 5) are interconnected by means of at least one further connecting device (14) and wherein a length of a latch arm (22) of the connecting device (14) corresponds to the distance A.

2. Device for power contacting (1) according to claim 1, characterised in that the openings (6, 7) are round or angular.

3. Device for power contacting (1) according to claim 1, characterised in that the contact arms (8, 9) comprise a camber and/or imprint in the latter.

4. Device for power contacting (1) according to claim 1, characterised in that the two partial contacts (4, 5) are interconnected by means of two connecting devices (14), in particular two connecting devices (14) of a similar design.

5. Device for power contacting (1) according to claim 1, characterised in that the electrical connection (3) is integral with the contact pin holder (2).

6. Device for power contacting (1) according to claim 1, characterised in that the electrical connection (3) is a component which can be connected to the contact pin holder (2) and comprises a connecting portion (15) for this purpose.

7. Device for power contacting (1) according to claim 1, characterised in that the electrical connection (3) comprises a connection end (16), in particular designed as a blade, contact button, crimp, solder end or rivet.

8. Device for power contacting (1) according to claim 6, characterised in that the connecting portion (15) of the electrical connection (3) is trident-shaped, the two outer arms (17) of the trident being bent so as to be spaced in alignment above and below the middle arm (18).

9. Device for power contacting (1) according to claim 8, characterised in that the distance from the upper (17) to the middle arm (18) and from the lower (17) to the middle arm (18) corresponds to a material thickness of the contact element (2), and in that the thickness of the middle arm (18) corresponds to a distance between the two partial contacts (4, 5).

10. Device for power contacting (1) according to claim 1, characterised in that the respective connection surfaces of the partial contacts (4, 5) and the electrical connection (3) comprise corresponding gratings (19).
