Abstract

A terminal pin includes a substantially elongate pin body having a longitudinal axis and a terminal head, the terminal head having an opening for receiving a wire, the opening extending substantially transverse to the longitudinal axis. This results in a substantial reduction in space required as compared to other connection structures.

Claims

1. A method for connecting a pin and a wire, comprising the steps of:

providing a terminal pin comprising a substantially elongate pin body having a threaded portion, a longitudinal axis and a terminal head, the terminal head having an opening for receiving a wire, the opening extending substantially transverse to the longitudinal axis;

positioning a wire in the opening; and

crimping the terminal head of the pin so as to secure the wire in the opening.

2. The method of claim 1, wherein the terminal head comprises a flange and an extension from the flange, and wherein the opening extends through the extension.

3. The method of claim 2, wherein the extension has an end with a concave surface defined thereon, whereby application of a crimping force to the concave surface crimps the wire within the opening.

4. The method of claim 2, wherein the extension has a tapering wall surface which narrows in a direction away from the flange.

5. The method of claim 2, wherein the extension is a substantially round member.

6. The method of claim 1, wherein the opening is substantially perpendicular to the longitudinal axis of the pin body.

7. The method of claim 1, wherein the crimping comprises applying a longitudinal crimping force to a longitudinal end surface of the head.

8. The method of claim 7, wherein the crimping force is applied to a concave portion of said end surface.

9. A method for forming an electrical connection, the method comprising:

connecting, according to claim 1, said pin and said wire; and

securing the threaded portion within a piece of machinery.

10. The method of claim 9, wherein the securing precedes the connecting.

11. The method of claim 10, wherein the crimping comprises applying a longitudinal crimping force to a longitudinal end surface of the head.

12. The method of claim 11, wherein the extension has an end with a concave surface and wherein the crimping force is applied to the concave surface.

13. The method of claim 2, wherein the extension has an end with a concave surface and wherein the crimping force is applied to the concave surface.

14. The method of claim 3, wherein the crimping comprises applying said crimping force longitudinally to the concave surface.

15. The method of claim 1, wherein the opening comprises a threaded bore.

16. The method of claim 1, wherein a surface of the opening has gripping structures and, upon the crimping, the gripping structures hold the wire secured in the opening.

17. A method for connecting a pin and a wire, comprising the steps of:

providing a terminal pin comprising a substantially elongate pin body having a longitudinal axis and a terminal head, the terminal head having;

an opening for receiving a wire, the opening extending substantially transverse to the longitudinal axis;

a substantially round flange;

an extension from the flange, the opening extending through the extension;

positioning a wire in the opening; and

crimping the terminal head of the pin so as to secure the wire in the opening.

18. The method of claim 17 wherein:

the extension has an end with a concave surface thereon; and

the crimping comprises application of a crimping force to the concave surface to crimp the wire within the opening.

19. The method of claim 17, wherein the crimping comprises applying a longitudinal crimping force to a longitudinal end surface of the head.

20. The method of claim 17, wherein the opening is substantially perpendicular to the longitudinal axis of the pin body.
