US 4,778,404 A · Spring terminal

Abstract

A longitudinally resilient electrical terminal is stamped and formed from a unitary piece of metal stock and has a front contacting body, an intermediate spring body and a rear body including conductor terminating means. The intermediate spring portion is formed by a number of spring sections each of which has pairs of legs angularly positioned with respect to each other and joined at their adjacent ends to form a zig-zag configuration. The terminal is formed into a generally cylindrical shape with the intermediate portion providing somewhat of a helical spring configuration and resulting action. The amount of spring force generated by the subject terminal is determined by the stock characteristics, as well as the number of spring sections, the relative angle between the legs, and the tightness of the curl in forming the cylindrical configuration. The conductor terminating means can be a crimp or other known means. The subject terminal is preferably utilized in a known connector configuration and can quite effectively be used in a sealed environment.

Dependent claims

A stamped and formed electrical terminal comprising:

a contact portion, a continuous noncoiled intermediate spring portion and a conductor-terminating portion;
said intermediate spring portion having first and second ends, said first end being joined to said contact portion and said second end being joined to said conductor-terminating portion, said intermediate spring portion being formed into a continuous series of spring sections having first and second legs, the first leg of the first spring section being the first end of said intermediate spring portion and the second leg of said first spring section being joined to the first leg of an adjacent spring section, the first and second legs of each succeeding spring sections being joined to respective second and first legs of adjacent spring sections and the second leg of the last spring section being the second end of said intermediate spring portion, said spring portions being formed in a noncoiled generally cylindrical configuration, whereby said intermediate spring portion provides axial spring forces to resiliently engage said terminal with a mating terminal.
