Abstract

A conductor terminal with a busbar piece and a clamping spring. The clamping spring has a clamping limb which is oriented towards the busbar piece in order to form a clamping point for clamping an electric conductor between the clamping limb and the bus bar piece, a spring bracket which adjoins the clamping limb, and a contact limb, a vertical section of which extends transversely to the bus bar piece. The vertical section of the contact limb has a recess with edges which surround the bus bar piece. The bus bar piece has a contact wall which adjoins the wall surface of the contact limb vertical section extending transversely to the busbar piece. The wall surface lying on the vertical section side facing away from the clamping limb, and which is designed to support the vertical section of the contact limb on the contact wall by means of the wall surface facing away from the clamping limb.

First claim

What is claimed is:

1. A conductor terminal comprising:
a busbar piece; and
a clamping spring that includes a clamping limb oriented towards the busbar piece to form a clamping point for clamping an electric conductor between the clamping limb and the busbar piece, a spring bend adjoining the clamping limb and a contact limb having a vertical section that extends transversely to the busbar piece, the vertical section of the contact limb having a recess with edges surrounding the busbar piece,
wherein the busbar piece has a contact wall, which is disposed on a contact wall surface of the vertical section of the contact limb, the contact wall surface of the vertical section being arranged on a side of the vertical section facing away from the clamping limb,
wherein the contact wall of the busbar piece supports the vertical section of the contact limb via the contact wall surface of the vertical section that faces away from the clamping limb.

2. The conductor terminal according to claim 1 , wherein a transverse web is formed on the recess of the vertical section of the contact limb, which engages with the busbar piece from below, the busbar piece being inserted into the recess, and wherein one of the edges of the recess of the vertical section, which is opposite the transverse web and which delimits the recess is supported on the busbar piece.

3. The conductor terminal according to claim 1 , wherein the vertical section of the contact limb has a notch at a distance from the recess, and wherein a finger projects from the contact wall of the busbar piece, the finger being inserted into the notch.

4. The conductor terminal according to claim 3 , wherein the finger wraps around a portion of the vertical section of the contact limb, such that an end of the finger abuts a wall surface of the vertical section which opposes the contact wall surface of the vertical section.

5. The conductor terminal according to claim 1 , wherein a horizontal section of the contact limb extending in a main extension direction of the busbar piece is bent away from the vertical section, and wherein the horizontal section is disposed at a distance from the busbar piece and transitions into the spring bend.

6. The conductor terminal according to claim 1 , wherein the horizontal section does not have a support on the busbar piece.

7. The conductor terminal according to claim 1 , wherein the clamping limb has an actuating section designed as a laterally projecting actuating bracket.

8. The conductor terminal according to claim 1 , wherein the conductor terminal has an insulator housing, which includes a clamping insert formed from the busbar piece and the clamping spring.

9. The conductor terminal according to claim 8 , wherein an actuating element is pivotably or movably supported in the insulator housing, wherein the actuating element is configured to strike an actuating section of the clamping limb when the actuating element is pivoted or moved.

10. The conductor terminal according to claim 1 , wherein the busbar piece includes two fork tines that are disposed at a distance from each other and are oriented to face each other to form a tuning fork contact socket, and wherein the contact wall is formed by a side edge of a connecting web that connects the two fork tines to each other.

11. The conductor terminal according to claim 10 , wherein a bracket projects from the connecting web, which abuts the vertical section and faces the clamping limb.

12. The conductor terminal according to claim 1 , wherein the busbar piece has a wavy cross-sectional profile designed with creases and elevations in an area in which the vertical section of the contact limb is supported.

13. The conductor terminal according to claim 1 , wherein a horizontal section of the contact limb, which extends in a main extension direction of the busbar piece and is disposed at a distance from the busbar piece and which transitions into the spring bend, is bent away from the vertical section of the contact limb, and wherein a holding section extends toward the busbar piece projecting away from the horizontal section and is supported on the busbar piece.

14. The conductor terminal according to claim 1 , wherein the contact wall is formed by an edge of the busbar piece facing the vertical section.

15. The conductor terminal according to claim 14 , wherein the contact wall connects fork tines of the busbar piece to each other via an edge of a connecting web facing the vertical section or is formed by an edge of a fork tine situated on the end of the fork tine opposite the clamping end of the fork tine.

16. The conductor terminal according to claim 1 , wherein the vertical section includes at least one side web, which is inserted into an assigned side recess of the busbar piece.

17. The conductor terminal according to claim 1 , wherein the contact limb includes a contact section, which adjoins the vertical section and is bent around from the vertical section, wherein a portion of the contact section abuts a clamping section of the busbar piece on a side of the clamping section that faces away from the clamping limb, and wherein another portion of the contact section is spaced apart from the clamping section of the busbar piece, such that a test area is provided.

18. The conductor terminal according to claim 3 , wherein the notch and the recess of the vertical section of the contact limb are each open-ended at one side thereof.

19. The conductor terminal according to claim 1 , wherein a distal end of the clamping limb faces and is spaced apart from a wall surface of the vertical section that opposes the contact wall surface of the vertical section of the contact limb.

20. The conductor terminal according to claim 11 , wherein the bracket solely directly contacts the vertical section of the contact limb.

21. A conductor terminal comprising:
a busbar piece; and
a clamping spring that includes a clamping limb oriented towards the busbar piece to form a clamping point for clamping an electric conductor between the clamping limb and the busbar piece, a spring bend adjoining the clamping limb and a contact limb having a horizontal section and a vertical section, the vertical section extending transversely to the busbar piece and the vertical section of the contact limb having a recess with edges surrounding the busbar piece,
wherein the busbar piece has a contact wall which is disposed on a contact wall surface of the vertical section of the contact limb, the contact wall surface of the vertical section being arranged on a side of the vertical section facing away from the clamping limb,
wherein the contact wall of the busbar piece supports the vertical section of the contact limb via the contact wall surface of the vertical section that faces away from the clamping limb, and
wherein the spring bend extends between the horizontal section of the contact limb and the clamping limb, and the horizontal section of the contact limb extends between the vertical section of the contact limb and the spring bend.

22. The conductor terminal according to claim 21 , wherein the contact limb includes a contact section, which adjoins the vertical section and is bent around from the vertical section, wherein a portion of the contact section abuts a clamping section of the busbar piece on a side of the clamping section that faces away from the clamping limb, wherein another portion of the contact section is spaced apart from the clamping section of the busbar piece, such that a tes
