Patent attributes
An apparatus for detachably-attaching a first half of an electrical connector to a second half includes an exterior first half housing as part of the first half that rotates about a split ring with respect to a remaining interior portion of the first half. The interior portion does not rotate. The first half housing rotates during connection as the interior portion is urged longitudinally. Electrical sockets and electrical contact pins are provided in the first half and the second half. The first half housing includes inward-protruding pins that engage with outward facing slots of the second half and follow the contour of the slots as the first half housing is rotated causing a longitudinal displacement of the first half with respect to the second half. The slots and housing structure prevent flame propagation by providing complete electrical disconnection before a final mechanical release of the bayonet connection occurs.
