Abstract

Abstract Stamped and formed electrical contact terminal comprises a crimp portion of U-shaped cross section and a contact portion in the form of a tongue extending from the crimp portion. The tongue is reversely bent and has a locking section extending into the crimp portion. Upon crimping of the crimp portion onto a wire, the locking section is locked to the crimped connection to provide a closed entry receptacle. Connector housing for the disclosed terminal has a cavity such that the terminal need not be preferentially oriented during insertion.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 203 words
A stamped and formed electrical contact terminal which is adapted to be crimped onto a wire, said terminal comprising: a ferrule portion comprising a bight and sidewalls, said sidewalls being adapted to be curled inwardly towards each other and crimped onto said wire, a contact portion comprising an extension of said bight, said contact portion having a reverse bend, and a reversely extending portion extending from said reverse bend, and having an integral locking section on its end, said locking section being between said sidewalls, said contact portion having retention lances, one of said lances being on each side of an axis of said terminal which extends medially in the direction of said bight, said lances being integral with said contact section at said reverse bend and extending generally tangentially from said reverse bend rearwardly towards said ferrule portion and laterally away from said bight whereby, upon placement of a wire between said sIdewalls and crimping of said sidewalls onto said wire, said locking section is clamped tightly against said bight and said reversely extending portion is circumferentially stressed, and said lances are moved outwardly from said bight and set so that they extend at a predetermined angle with respect to said bight.
Claim 2
Dependent Claim 203 words
A stamped and formed electrical contact terminal which is adapted to be crimped onto a wire, said terminal comprising: a ferrule portion comprising a bight and sidewalls, said sidewalls being adapted to be curled inwardly towards each other and crimped onto said wire, a contact portion comprising an extension of said bight, said contact portion having a reverse bend, and a reversely extending portion extending from said reverse bend, and having an integral locking section on its end, said locking section being between said sidewalls, said contact portion having retention lances, one of said lances being on each side of an axis of said terminal which extends medially in the direction of said bight, said lances being integral with said contact section at said reverse bend and extending generally tangentially from said reverse bend rearwardly towards said ferrule portion and laterally away from said bight whereby, upon placement of a wire between said sIdewalls and crimping of said sidewalls onto said wire, said locking section is clamped tightly against said bight and said reversely extending portion is circumferentially stressed, and said lances are moved outwardly from said bight and set so that they extend at a predetermined angle with respect to said bight.
