Abstract

A busbar contact includes a contact ring and a fastening element. The contact ring has a contact surface at a distal end and a press-in flange projecting radially. The press-in flange has a cylindrical contact surface pointing radially outward.

First claim

What is claimed is:

1. A busbar contact, comprising:
a contact ring having a contact surface at a distal end;
a fastening element, the fastening element and the contact ring have complementary press-on surfaces that taper in a direction opposite to a direction of connection between the contact ring and the fastening element, the press-on surface of the contact ring is an inner surface of the contact ring and the press-on surface of the fastening element is an outer surface of the fastening element; and
a counter element connecting to the fastening element, the counter element and the contact ring abut opposite sides of a busbar and the fastening element directly contacts the busbar.

2. The busbar contact of claim 1 , wherein the counter element has a radially projecting flange with a plurality of toothed element projecting from a front side of the radially projecting flange.

3. The busbar contact of claim 1 , wherein the fastening element has a screw thread.

4. The busbar contact of claim 1 , wherein the contact ring has a receiving channel receiving the fastening element.

5. The busbar contact of claim 1 , further comprising a touch guard cap attached to a distal end of the fastening element.

6. An assembly, comprising:
a busbar having a hole; and
a busbar contact fitted in the hole, the busbar contact including a contact ring having a contact surface at a distal end and a press-in flange projecting radially from the contact ring, the press-in flange having a cylindrical contact surface pointing radially outward, the cylindrical contact surface abuts against a mating pressing surface in the hole of the busbar, an edge of the hole is deformed to form a bead from a portion of the busbar that engages the press-in flange and secures the contact ring in the hole, the bead is formed from only the busbar; wherein
the busbar contact has a fastening element received in the contact ring.

7. The assembly of claim 6 , wherein the hole has a stepped bore.

8. The assembly of claim 6 , wherein the press-in flange has a rectangular radial cross section.

9. The assembly of claim 6 , wherein the busbar contact has a fastening element with a screw thread that is an internal thread.

10. The assembly of claim 9 , wherein the fastening element has a press-on flange directly contacting the press-in flange and pressing the contact ring.

11. The assembly of claim 10 , wherein the press-in flange is wider than the press-on flange.

12. The assembly of claim 9 , wherein the fastening element has a clamping projection clamping to the contact ring.

13. The assembly of claim 9 , wherein the contact ring has a receiving channel receiving the fastening element.

14. The assembly of claim 9 , further comprising a touch guard cap attached to a distal end of the fastening element.

15. A method for fastening a busbar contact to a busbar, comprising:
providing the busbar contact including a contact ring having a contact surface at a distal end and a press-in flange projecting radially from the contact ring, the press-in flange having a cylindrical contact surface pointing radially outward; and
positioning the press-in flange in a hole of the busbar; and
reducing a size of an edge of the hole by deformation to form a bead from a portion of the busbar that engages behind the press-in flange and secures the contact ring in the hole, the bead is formed from only the busbar; wherein
the busbar contact has a fastening element inserted into the contact ring and through the hole of the busbar.
