ABSTRACT:
A high durability drawer connector is capable of blind mating and has a receptacle connector half having a plurality of spring arm contact terminals extending forwardly of a mating face, and a plug connector half having a like plurality of contact terminals having planar contact portions to engage the spring arm contacts upon mating. Guide pins forwardly of the plug housing enter alignment recesses of the receptacle housing and align the plug connector which is floatingly mounted to a drawer end panel. At a first unmated position the spring arms enter plug housing passageways and just engage the plug's contacts under low insertion force. A camming bearing surface on one of the plug's guide pins bears against a cooperating surface of the receptacle housing and cams the plug connector in a selected axially normal direction. The plug's contacts then firmly engage the spring arms from laterally thereof biasing them to achieve contact force, and the connectors are fully mated. An improved plug connector floating mounting means is also provided which centers the plug prior to mating, and can be used on standard drawer connectors requiring alignment.
