Abstract
A self-locking female electrical socket having an automatic release mechanism. The female socket includes releasable balls that urged into locking engagement with the prongs of a male plug. The plug may be released for reasons of maintaining cord in tact through deflection of a deflectable element positioned adjacent the prong.
Claims11
A locking female electrical socket having an automatic release mechanism comprising
- a female socket body having a pair of holes for receiving the spaced prongs having punched holes of a male plug for electrically connecting two electrical lines respectively coupled to said female socket body and the male plug,
- said female socket body having actuator means being mounted for selective relative movement between a first and second position within said female socket body,
- locking means mounted in said female socket in operative relationship to said actuator means to permit insertion and removal of the prongs at a first position of said actuator means in said female socket and said locking means being rigidly urged by said actuator means into locking engagement with the holes of the spaced prongs in a second position of said actuator means in said socket body, and
- release means in said female socket body for releasing the prongs of the male plug from said female socket in said second position of said actuator means upon application of a predetermined pulling force between the male plug and said female socket, said release means is mounted in said female socket body against to the prongs of the male plug, said release means having at least one deflectable element resiliently biased against a prong.
