Electrical Terminal Pin

View page
US Patent:
51885476, Feb 23, 1993
Filed:
May 7, 1992
Appl. No.:
7/879637
Inventors:
Daniel A. Dixon - Naperville IL
Frederick J. Gierut - Tinley Park IL
Joe Lawniczak - Schaumburg IL
Arvind Patel - Naperville IL
Michael Primorac - Chicago IL
Assignee:
Molex Incorporated - Lisle IL
International Classification:
H01R 1302
US Classification:
439886
Abstract:
An electrical terminal pin is provided with a pin tip for insertion into a mating electrical female terminal, a hole in a printed circuit board or the like. The pin has an electrically conductive core plated with an electrically conductive layer. The pin tip is formed of a generally rounded pyramidal configuration defining four slightly curved convex sides joined at four edges converging at a pin end. Two opposite sides of the pin tip are non-plated. The other two opposite sides of the pin tip are plated with the conductive layer. Portions of the conductive plating layer overlap the edges of the pin tip in a smooth or rounded configuration to eliminate any sharpness thereof and to provide additional plated areas over the exposed core material. The pin tip is formed by a cutting and coining operation to form the configuration of the tip and to coin the overlapping portions of the conductive plating layer over the sharp edges of the pin tip.

US Patent:
52089789, May 11, 1993
Filed:
Oct 1, 1992
Appl. No.:
7/955186
Inventors:
Daniel A. Dixon - Naperville IL
Frederick J. Gierut - Tinley Park IL
Joe Lawniczak - Schaumburg IL
Arvind Patel - Naperville IL
Michael Primorac - Chicago IL
Assignee:
Molex Incorporated - Lisle IL
International Classification:
H01R 1303
US Classification:
29874
Abstract:
A method of fabricating a pin tip is provided by a cutting and coining operation which first forms a pin tip which has a generally rounded configuration defining 4 slightly curved convex sides joined at 4 edges converging at a pin end. Thereafter the pin tip is coined again thereby overlapping portions of the conductive plating layer over the sharp edges of the pin tip.
