Electrical connector and method of making the same
View Patent ↗In one aspect, the invention provides a method for making an electrical connector. The method may include: obtaining a part having a first end portion, a second end portion, and an interim 1 portion between the first and second end portions; flattening the second end portion; trimming the flattened second end portion; and forming a hole in the flattened second end portion.
1. A method for making an electrical connector, comprising:
obtaining a part having a first end portion, a second end portion, and an interim portion between the first and second end portions;
flattening the second end portion, wherein the flattened second end portion has a first face and a second face;
trimming the flattened second end portion; and
forming a hole in the flattened second end portion, the hole extending from the first face to the second face, wherein
the step of trimming the flattened second end portion comprises removing portions of the flattened second end portion, thereby forming the flattened end portion into a desired shape, and
after the trimming step is performed, the flattened second end portion has a first end section, a second end section and an interim section between the first and second end sections, wherein the first end section is between the interim portion of the part and the interim section of the flattened second end section, and wherein the first end section of the flattened second end portion has a generally uniform width and a width of the interim section of the flattened second end portion is greater than the width of the first end section.
2. The method of claim 1 , wherein the first end portion of the part has been chamfered.
3. The method of claim 1 , wherein the first end portion of the part comprises a pointy end section.
4. The method of claim 1 , wherein the part has a retention star formed thereon.
5. The method of claim 1 , wherein the part comprises a plurality of members, each member extending radially from an outer surface of the interim portion of the part.
6. The method of claim 1 , wherein the part is a wire formed pin having a chamfered mating end.
7. The method of claim 1 , wherein the thickness of the flattened second end portion is between about 0.01 to 0.06 inches.
8. The method of claim 7 , wherein the thickness of the flattened second end portion is about 0.030 inches.
9. The method of claim 7 , wherein the length of the second end portion is between about 0.45 to 0.1 inches.
10. The method of claim 9 , wherein the length of the second end portion is about 0.2 inches.
11. The method of claim 9 , wherein the length of the part is between about 1 and 4 inches.
12. The method of claim 11 , wherein the length of the part is about 2 inches.
13. The method of claim 1 , wherein the interim section of the flattened second end portion has a non-uniform width, which width is greatest across the middle of the interim section.
14. The method of claim 1 , wherein the second end section has a generally pointed end.
15. The method of claim 1 , wherein the hole is generally elliptical in shape.
16. The method of claim 1 , further comprising selectively plating the part.
17. The method of claim 1 , wherein the part is generally elongate, cylindrical, rigid.
18. The method of claim 1 , wherein the length of the hole is substantially ⅔ the length of the interim section of the flattened second end portion.
