Abstract

A single element electrical connector includes a single conductive contact element formed into a cage structure having a wire insert end and a wire contact end along a longitudinal centerline axis of the connector. The cage structure defines an upper pick-up surface having a surface area suitable for placement of a suction nozzle of a vacuum transfer device, as well as a pair of contact tines biased towards the centerline axis to define a contact pinch point for an exposed core of a wire inserted into the connector. A contact surface is defined by a member of the cage structure for electrical mating contact with a respective contact element on a component on which the connector is mounted.

First claim

What is claimed is:

1. An electrical connector comprising:
a conductive contact element comprising a plurality of contact surfaces, wherein the conductive contact element comprises:
an insert end comprising an inlet opening;
a contact end opposite the insert end; and
a first contact tine and a second contact tine each biased toward a centerline axis of the conductive contact element downstream of the wire insert end in an insertion direction into the conductive contact element, wherein the first and second contact tines define a contact pinch point, wherein at least one of the first or second contact tines comprises a first release tab and a second release tab configured to enable selective separation of the two or more contact tines.

2. The single element electrical connector of claim 1 , wherein the conductive contact element connector consists of a single piece of electrically-conductive material.

3. The single element electrical connector of claim 1 , wherein the first and second release tabs comprise extensions from a main body portion of the at least one of the first or second contact tines.

4. The single element electrical connector of claim 1 , wherein the first and second release tabs extend in a direction of the centerline axis.

5. The single element electrical connector of claim 1 , wherein the single element electrical connector does not include an insulator.

6. The single element electrical connector of claim 1 , wherein the first release tab is located on a first side of the at least one of the first or second contact tines, wherein the second release tab is located on a second side of the at least one of the first or second contact tines, and wherein the first side is opposite the second side.

7. The single element electrical connector of claim 1 , wherein the first and second contact tines extend from a base portion at the insert end in which the inlet opening is formed.

8. The single element electrical connector of claim 7 , wherein the at least one of the first or second contact tines comprises a bent-over extension of the base portion.

9. The single element electrical connector of claim 7 , wherein the first and second contact tines are angled towards the centerline axis to define a space that guides an inserted wire to the contact pinch point.

10. The single element electrical connector of claim 7 , wherein at least one contact surface of the plurality of contact surfaces comprises contact feet extending generally transversely from the base portion such that, upon mounting of the electrical connector to a component, the centerline axis is generally perpendicular to the component.

11. The single element electrical connector of claim 7 , wherein the base portion comprises at least one contact surface of the plurality of contact surfaces.

12. The single element electrical connector of claim 7 , wherein the conductive contact element comprises a raised portion between at least one contact surface of the plurality of contact surfaces and the base portion such that, upon mounting of the conductive contact element to a mounting surface, the base portion is positioned at a greater distance from the mounting surface than the plurality of contact surfaces is positioned from the mounting surface.

13. The single element electrical connector of claim 12 , wherein the first and second contact tines extend from the base portion in a direction away from the plurality of contact surfaces.

14. The single element electrical connector of claim 12 , wherein the first and second contact tines extend from the base portion in a direction back toward the plurality of contact surfaces.

15. The electrical connector of claim 1 , wherein the first and second release tabs extend from a forward-most portion of the at least one of the first or second contact tines.

16. The electrical connector of claim 15 , wherein the first release tab is spaced apart from the second release tab on the at least one of the first or second contact tines such that a gap is formed between the first release tab and the second release tab.

17. An electrical device comprising:
a conductive contact element comprising a plurality of contact surfaces, wherein the conductive contact element comprises:
an insert end comprising an inlet opening;
a contact end opposite the insert end; and

a first contact tine and a second contact tine each biased toward a centerline axis of the conductive contact element downstream of the wire insert end in an insertion direction into the conductive contact element, wherein the first and second contact tines define a contact pinch point, wherein at least one of the first or second contact tines comprises a first release tab and a second release tab configured to enable selective separation of the two or more contact tines; and
a printed circuit board comprising one or more contact pads, wherein the one or more contact pads are electrically connected to the plurality of contact surfaces.

18. The electrical device of claim 17 , wherein the printed circuit board comprises an opening that corresponds to the inlet opening of the conductive contact element such that the centerline axis of the conductive contact element runs through the opening of the printed circuit board, and wherein the first and second contact tines extend through the opening in the printed circuit board.

19. The electrical device of claim 17 , further comprising a wire extending through the opening in the printed circuit board and through the inlet opening of the conductive contact element, wherein the wire is electrically connected to the conductive contact element via the first and second contact tines.

20. The electrical device of claim 17 , wherein the first and second release tabs extend from a forward-most portion of the at least one of the first or second contact tines, and wherein the first release tab is spaced apart from the second release tab on the at least one of the first or second contact tines such that a gap is formed between the first release tab and the second release tab.
