Abstract

A contact insert of a conductor terminal for connecting at least one electrical conductor, wherein the contact insert comprises at least one bus bar and at least one clamping spring, wherein the bus bar has at least one through opening, wherein the contact insert has a perforated collar which is designed as a component separate from the bus bar, wherein the perforated collar circumferentially surrounds the through opening at least partially or completely on at least one side of the bus bar.

First claim

What is claimed is:

1. A contact insert of a conductor terminal for connecting at least one electrical conductor, the contact insert comprising:
at least one bus bar having at least one through opening;
at least one clamping spring; and
a perforated collar that is a separate component from the bus bar and is arranged on a side of the busbar that faces away from the clamping spring, the perforated collar circumferentially surrounding the through opening at least partially or completely on the side of the bus bar that faces away from the clamping spring.

2. The contact insert according to claim 1 , wherein the perforated collar is formed of a different material than the bus bar.

3. The contact insert according to claim 1 , wherein the perforated collar rests on the bus bar on the side facing away from the clamping spring.

4. The contact insert according to claim 1 , wherein the perforated collar is attached to the bus bar.

5. The contact insert according to claim 4 , wherein the perforated collar is attached to the bus bar by clamping, latching, gluing or a combination thereof.

6. The contact insert according to claim 1 , wherein the perforated collar is formed circumferentially to form a through hole.

7. The contact insert according to claim 6 , wherein the through hole of the perforated collar is aligned with the through opening of the bus bar.

8. The contact insert according to claim 1 , wherein the bus bar has several through openings one behind the other and/or several through openings next to one another in a longitudinal direction, and wherein several or all of the through openings comprise a respective perforated collar, the perforated collars being designed as a common separate component or as a plurality of components separate from the bus bar.

9. A conductor terminal for connecting at least one electrical conductor, wherein the conductor terminal comprises:
a housing; and
the contact insert according to claim 1 .

10. The conductor terminal according to claim 9 , wherein a conductor receiving pocket is provided in the housing, wherein the perforated collar is arranged between the bus bar and the conductor receiving pocket.

11. A contact insert of a conductor terminal for connecting at least one electrical conductor, the contact insert comprising:
at least one bus bar having at least one through opening;
at least one clamping spring; and
a perforated collar that is a separate component from the bus bar, the perforated collar circumferentially surrounding the through opening at least partially or completely on at least one side of the bus bar,
wherein the perforated collar is a conductor guide element that peripherally, at least partially or entirely, forms a conductor guide for an electrical conductor to be connected to the contact insert.

12. The contact insert according to claim 11 , wherein the perforated collar has a conductor stop for the electrical conductor to be clamped and/or an overload stop so as to limit a maximum deflection of the clamping spring.

13. The contact insert according to claim 12 , wherein at least one area of the perforated collar protrudes into the area of the through opening to form the overload stop.

14. A contact insert of a conductor terminal for connecting at least one electrical conductor, the contact insert comprising:
at least one bus bar having at least one through opening;
at least one clamping spring; and
a perforated collar that is a separate component from the bus bar, the perforated collar circumferentially surrounding the through opening at least partially or completely on at least one side of the bus bar,
wherein the bus bar has a clamping tab in an area of the through opening that is formed from the material of the bus bar and angled relative to the surface of the bus bar on which, together with the clamping spring, a clamping point for an electrical conductor to be clamped is formed.

15. The contact insert according to claim 14 , wherein the clamping tab extends at least partially into the space surrounded by the perforated collar.
