Single element wire to board connector
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.
1. An electrical connector comprising:
a contact element comprising:
an inlet opening;
a contact end opposite the inlet opening; and
a first contact tine and a second contact tine each biased toward a centerline axis of the contact element downstream of the inlet opening in an insertion direction into the contact element, wherein the first and second contact tines define a contact pinch point, and wherein the first contact tine comprises a plurality of tabs extending from a distal portion of the first contact tine.
2. The electrical connector of claim 1 , wherein the contact element consists of a single piece of electrically-conductive material.
3. The electrical connector of claim 1 , wherein the plurality of tabs comprises first and second tabs that are extensions from a main body portion of the first contact tine.
4. The electrical connector of claim 3 , wherein the first and second tabs extend in a direction of the centerline axis.
5. The electrical connector of claim 1 , wherein the electrical connector does not include an insulator.
6. The electrical connector of claim 1 , wherein a first tab is located on a first side of the first contact tine, wherein a second tab is located on a second side of the first contact tine, and wherein the first side is opposite the second side.
7. The electrical connector of claim 1 , wherein the first and second contact tines extend from a base portion at the inlet opening.
8. The electrical connector of claim 7 , wherein the first contact tine comprises a bent-over extension of the base portion.
9. The electrical connector of claim 7 , wherein the first and second contact tines are angled toward the centerline axis to define a space that guides an inserted wire to the contact pinch point.
10. The electrical connector of claim 7 , wherein the contact element further 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 electrical connector of claim 7 , wherein the base portion comprises an electrically-conductive contact surface.
12. The electrical connector of claim 11 , wherein the contact element comprises a raised portion between the electrically-conductive contact surface and the base portion such that, upon mounting of the contact element to a mounting surface, the base portion is positioned at a greater distance from the mounting surface than the electrically-conductive contact surfaces is positioned from the mounting surface.
13. The electrical connector of claim 12 , wherein the first and second contact tines extend from the base portion in a direction away from the electrically-conductive contact surface.
14. The electrical connector of claim 12 , wherein the first and second contact tines extend from the base portion in a direction back toward the electrically-conductive contact surface.
15. The electrical connector of claim 1 , wherein the plurality of tabs extend from a forward-most portion of the first contact tine.
16. The electrical connector of claim 15 , wherein the first tab is spaced apart from the second tab on the first contact tine such that a gap is formed between the first tab and the second tab.
17. An electrical device comprising:
a conductive contact element comprising one or more contact surfaces, wherein the conductive contact element comprises:
an inlet opening;
a contact end opposite the inlet opening; and
a first contact tine and a second contact tine each biased toward a centerline axis of the conductive contact element downstream of the inlet opening in an insertion direction into the conductive contact element, wherein the first and second contact tines define a contact pinch point, and wherein the first contact tine comprises a plurality of tabs extending from a distal portion of the first contact tine; and
a printed circuit board comprising one or more contact pads, wherein the one or more contact pads are electrically connected to the one or more 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 tabs extend from a forward-most portion of the first contact tine, and wherein the first tab is spaced apart from the second tab on the first contact tine such that a gap is formed between the first tab and the second tab.
