Abstract
Abstract An improved electrical terminal of the type wherein the male portion of the terminal comprises a cylindrical prong and the female portion of the terminal comprises a mating cylindrical hole, the improvement going specifically to the manner in which the female portion and male portion are resiliently biased internally into snug mating contact with one another to ensure the reliable and uninterrupted transmission of electrical current therebetween. Specifically, the resilient biasing means preferably comprises a short bent wire captively contained within a longitudinal slot in the male prong.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
191 words
In an electrical terminal including a male portion having a cylindrically shaped insertion end for use in conjunction with the mating female portion having a cylindrical hOle of a diameter slightly larger than said insertion end into which the insertion end is inserted to make an electrical connection, said insertion end including a slot with a spring member therein which juts partially out of said slot to engage the inner sidewall of the female portion and maintain a good electrical connection between the male portion and the female portion, the improvement comprising: said insertion end being defined in part by a hole extending transversely thereof and adjacent its forwardmost extremities, said hole initiating at the base of said slot; said spring member having one major bend therein forming said spring member into generally an L shape of which one end is disposed within said transverse hole, the remainder of the spring member curving rearwardly therefrom in said slot to the other end, and means for positively holding said spring in said slot, said means partially closing said slot over a portion of said spring member to thereby prevent its free removal.

Claim 3
Dependent Claim
54 words
The improvement as defined in claim 1, wherein said L shaped spring member has a long leg and a short leg, said long leg comprising said remainder of the spring member and including an additional but lesser bend than said major bend to provide extended engagement between said spring member and said female portion.
