EMI: X-Ray protected multi-contact connector

Claim 1

A multi-contact plug and receptacle electrical connector comprising: A. the receptacle comprising: a conductive metal housing for mating with the plug including a face having perforations therein, said metal being capable of absorbing a substantial amount of X-ray radiation striking said face; said face being thick enough to cause X-ray radiation entering said perforations at an angle to said face to be shielded from striking the electrical sockets positioned beneath said perforations; the dimensions of said perforations being selected to form wave traps having a cut-off frequeny above the frequency of radio frequency electromagnetic energy striking said face during operational use of said receptacle; and an insulator insert positioned beneath said face enclosing the sides of said sockets; B. the plug comprising: a conductive metal housing for mating with said receptacle, said plug metal being capable of absorbing a substantial amount of X-ray radiation striking said plug; an insulative insert positioned within said plug housing, said plug insert enclosing a portion of the length of electrical pin contacts for making electrical connection with sockets of said receptacle, and also enclosing a barrel portion of said pin contacts; C. means for locking said receptacle and said plug in the mated relation; D. means for rapidly unlocking said plug and receptacle and for disengaging said plug and receptacle from the mated relation; and E. said means for locking and for rapidly unlocking said receptacle and plug including, in combination with said plug, a tubular means terminating in collet fingers, each of said fingers terminating in a finger tip, said finger tips being capable of closing to a roughly ball shape and opening to an expanded diameter; a plunger movable longitudinally within said collet fingers and said collet finger tips, whereby when said plunger is in the extreme forward position, said finger tips cannot move inwardly and are locked in the expanded position within a recess included in said receptacle; spring means associated with said plunger for maintaining said plunger in the forward position; spring means associated with said tubular means for imparting rearward movement of said collet finger tips out of said recess, whereby said receptacle and said plug are unlocked and electrically disengaged.
