Abstract

A releasably coupleable electrical connector assembly generally comprising first and second, mating, tubular connectors. The first tubular connector includes a generally square, elongated, tubular body portion and a locking tab catch portion. An inner surface of the body portion of the first tubular connector includes a protruding shoulder portion which is operable to engage with a shoulder portion of an elongated, electrical terminal pin to thereby hold the terminal pin captively and securely within the body portion after the terminal pin has been inserted therein. The second tubular connector includes a generally square, elongated tubular body portion and a planar, elongated tongue-like element having a tab element protruding therefrom. The body portion of the second tubular connector further includes an internal locking shoulder portion for lockably engaging with a mating electrical terminal after the terminal pin is inserted within the body portion of the second tubular connector, to thereby captively and securely hold the mating electrical terminal therewithin. The tubular connectors are coupled together by slidably inserting the body portion of the second tubular connector within the body portion of the first tubular connector. This causes the electrical terminal pin to be inserted within the mating electrical terminal, and the tab element of the planar, elongated tongue portion to be releasably, lockably engaged with the locking tab catch portion of the first tubular connector. Uncoupling is accomplished by simply lifting up on the locking tab catch portion and slidably removing the second tubular connector from the first tubular connector.
