Abstract

A conductor connection contact element for clamping an electrical conductor having at least one resilient force clamping connection. At least one first SMD-solder contact is arranged on an assembly face of the conductor connection contact element and configured for soldering to a contact surface. A conductor inserting region is formed by a sheet metal part of the conductor connection contact element. At least one conductor guiding base is oriented so as to form a guiding surface for the electrical conductor that is to be inserted. A material portion of the sheet metal part is adapted to be bent over at least one curved region to form a first SMD-solder contact and a region of the conductor guiding base that is oriented in an oblique manner with respect to the conductor inserting direction is adjacent to the at least one curved region.

First claim

What is claimed is:

1. A conductor connection contact element for clamping an electrical conductor, the conductor connection contact element comprising:
at least one resilient force clamping connection having a clamping site for fixedly clamping the electrical conductor, the conductor connection contact element configured as an (SMD-) conductor connection contact element that is adapted to be surface-mounted on an electrical circuit board;
at least one first SMD-solder contact arranged on an assembly face of the conductor connection contact element and configured for soldering to a contact surface of the circuit board;
a conductor inserting region formed by a sheet metal part of the conductor connection contact element;
at least one conductor guiding base that is oriented in an oblique manner with respect to the conductor inserting direction so as to form a guiding surface for the electrical conductor that is to be inserted; and
a material portion of the sheet metal part that is provided in the conductor inserting region and protrudes from the conductor guiding base being adapted to be bent over at least one curved region in a direction of a plane of an assembly face to form a first SMD-solder contact and at least one part region of the conductor guiding base that is oriented in an oblique manner with respect to the conductor inserting direction is adjacent to the at least one curved region.

2. The conductor connection contact element according to the claim 1 , wherein the first SMD-solder contact comprises a contact area that is configured so as to make contact with the contact surface of the circuit board, and wherein the contact area is spaced apart from the conductor guiding base over the at least one curved region.

3. The conductor connection contact element according to the claim 2 , wherein the contact area is formed by an end-face end surface of the material portion of the sheet metal part that protrudes from the conductor guiding base or by a surface of the material portion that adjoins the outer face of the at least one curved region.

4. The conductor connection contact element according to the claim 1 , wherein the material portion of the sheet metal part that protrudes from the conductor guiding base is bent over precisely one curved region or over two curved regions that each curve in an opposite direction to form the first SMD-solder contact.

5. The conductor connection contact element according to the claim 1 , wherein the conductor connection contact element comprises, in the conductor inserting region, a conductor inserting duct that comprises the conductor guiding base.

6. The conductor connection contact element according to the claim 1 , wherein the clamping site is arranged when viewed in the conductor inserting direction downstream of the conductor guiding base and/or downstream of the first SMD-solder contact.

7. The conductor connection contact element according to the claim 1 , wherein the first SMD-solder contact protrudes in an opposite direction to the conductor inserting direction from the conductor guiding base over the conductor inserting region of the conductor connection contact element.

8. The conductor connection contact element according to the claim 1 , wherein the conductor guiding base is formed by at least two mutually separate material portions of the sheet metal part or different sheet metal parts, and wherein the first SMD-solder contact is formed from an extended material portion from one of the sheet metal parts or from the sheet metal parts.

9. The conductor connection contact element according to the claim 1 , wherein the conductor connection contact element comprises a second SMD-solder contact that is arranged in the conductor inserting direction downstream of the first SMD-solder contact.

10. The conductor connection contact element according to the claim 1 , wherein the conductor connection contact element comprises as parts of the resilient force clamping connection for clamping an electrical conductor a current rail piece that is formed from the sheet metal part of the conductor connection contact element or from another sheet metal part having:
a first side wall and a second side wall that is lying opposite the first side wall, a base portion that extends from the first side wall to the opposite-lying second side wall, and a cover portion that lies opposite the base portion and extends from the first side wall towards an opposite-lying second side wall, wherein the side walls together with the cover portion and the base portion or the conductor guiding base delimit a conductor inserting duct, and
a clamping spring arranged on the current rail piece and at a first end region comprises a contacting portion and at a second end region that lies opposite the first end region comprises a clamping portion having a clamping edge for clamping the electrical conductor,
wherein the contacting portion is arranged on the base portion of the current rail piece, and
wherein the clamping portion extends with a freely-movable end toward the cover portion.

11. The conductor connection contact element according to the claim 10 , wherein an actuating portion that is accessible for an actuating tool is provided when viewed in a transverse manner with respect to the conductor inserting direction of the clamping portion in a direction of the side wall adjacent to the clamping edge.

12. The conductor connection contact element according to the claim 11 , wherein the actuating portion is configured as an actuating lug that protrudes sideward at the clamping portion of the clamping spring and that protrudes sideward out of the first side wall.

13. The conductor connection contact element according to the claim 12 , wherein the first side wall has an opening for a through-passage of the actuating lug.

14. The conductor connection contact element according to the claim 11 , wherein a conductor guiding element that adjoins the clamping portion is formed on the first side wall, wherein the conductor guiding element comprises a portion of the first side wall that is oriented in an oblique manner in the direction of the opposite-lying second side wall.

15. The conductor connection contact element according to the claim 14 , wherein the conductor guiding element is oriented facing away from an end edge of the first side wall that delimits the opening and lies opposite the second side wall.

16. The conductor connection contact element according to the claim 14 , wherein the conductor guiding element comprises a material tongue of the first side wall that is oriented in an oblique manner in the direction of the second side wall and toward the clamping portion.

17. The conductor connection contact element according to the claim 11 , wherein the actuating portion has an actuating lug that extends in the direction of the plane of the cover portion.

18. The conductor connection contact element according to the claim 11 , wherein the actuating portion has an actuating lug that is arranged sideward when viewed in the conductor guiding direction downstream of the free end of the conductor guiding element in an opening in the first side wall, the opening being accessible from an outside.

19. The conductor connection contact element according to the claim 11 , wherein at a rear end of the current rail piece that lies opposite the conductor inserting duct, an end stop is formed by a material tab that is bent out from a side wall from the base portion or from the cover portion.
