Abstract

An electric closer comprising a first connection lug, a second connection lug electrically insulated from the first connection lug, the first and second connection lugs each having at least one recess in a contact region disposed within a guide housing, an actuator for driving a contact element, the contact element being disposed in a guide housing between the actuator and the contact region of the connection lugs, and by the actuator from an open position, in which the connecting lugs are insulated from one another into a closed position, in which the connecting lugs are electrically connected to one another via the contact element, is displaceable, wherein in the closed position the contact element is accommodated in the recesses of the connecting lugs and wherein the contact element is guided in the displacement direction simultaneously in the respective recesses of the two connecting lugs during the displacement of the two connecting lugs.

First claim

What is claimed is:

1. Electric contactor comprising:
a first connection lug;
a second connection lug electrically insulated from the first connection lug, the first and second connection lugs each having at least one recess in a contact region arranged within a guide housing;
an actuator for driving a contact element, the contact element being arranged in a guide housing between the actuator and the contact region of the connecting lugs and being displaceable by the actuator from an open position, in which the connecting lugs are insulated from one another, into a closed position, in which the connecting lugs are electrically connected to one another via the contact element, the contact element being received in the recesses of the connecting lugs in the closed position,
wherein during the displacement the contact element is guided in the direction of displacement simultaneously in the respective recesses of the two connecting lugs; and
wherein the contact element is formed in at least one contact region, in which it is held in the recesses in the closed position, as a flat part, wherein the shape of the contact region is essentially complementary to the recesses of the connecting lugs.

2. Electric contactor according to claim 1 , wherein the contact element is formed at least partially from an electrically conductive material, preferably at least partially from an aluminium material and/or a copper material and/or in that the connecting lugs are formed at least partially from a conductive material, preferably at least partially from a copper material and/or an aluminium material.

3. Electric contactor according to claim 1 , wherein the surface normal of the surface of the contact region facing the recesses in the open position is substantially parallel to the displacement direction.

4. Electric contactor according to claim 1 , wherein the contact regions are spatially separated from one another, in particular that the contact regions lie opposite one another with respect to a central axis of the contact element extending parallel to the displacement direction, in particular that the distance between the contact regions is substantially equal to the distance between the recesses.

5. Electric contactor according to claim 1 , wherein the contact element is shaped and/or dimensioned relative to the recesses of the connecting lugs in such a way that, during displacement, a positive connection, in particular a press fit, a transition fit or a clearance fit is formed between the contact element and the connecting lugs.

6. Electric contactor according to claim 1 , wherein the connecting lugs each have a connecting part facing outward of the guide housing and a part arranged in the guide housing and guiding the contact element during displacement, and/or in that the receptacles are arranged on opposite sides of the guide housing.

7. Electric contactor according to claim 1 , wherein the recesses of the connecting lugs and the contact element have latching lugs and/or latching recesses which are shaped and dimensioned relative to one another in such a way that, during displacement, a positive connection, in particular a latching connection, is formed between the contact element and the connecting lugs.

8. Electric contactor according to claim 1 , wherein the guide housing has a guide channel in which the contact element is displaceably arranged.

9. Electric contactor according to claim 1 , wherein the contact region of the connection lugs is disposed at a first end of the guide channel and the actuator is disposed at a second end of the guide channel opposite the first end.

10. Electric contactor according to claim 1 , wherein at least one insulating element is arranged for insulating the contact element between the contact element and the contact region of the terminal lugs, the insulating element preferably being formed in two pieces, in particular from two insulating caps, in particular in that one of the insulating elements in each case covers at least the surface of the contact element facing the terminal lugs in the open position.

11. Electric contactor according to claim 1 , wherein the insulating element is formed from an insulating material, wherein the insulating material has a specific electrical conductivity of at least less than 10-5 S-cm-1, preferably less than 10-10 S-cm-1, particularly preferably 10-15 S-cm-1, in particular that the insulating material has a dielectric strength of at least more than 5 kV/mm, particularly preferably more than 20 kV/mm, especially preferably more than 50 kV/mm.

12. A motor vehicle with a power line and an electric contactor connected to the power line in accordance with claim 1 .

13. Electric contactor according to claim 1 , wherein the actuator comprises an actuator element and a displacement element, in particular that the actuator element is an electric, a hydraulic, a pyrotechnic or a mechanical actuator element.

14. Electric contactor according to claim 13 , wherein the displacement element is formed as a sliding carriage or as a bolt, the contact element being connected to the displacement element in a positive-locking, preferably force-locking, in particular material-locking manner.
