ABSTRACT:
A latching apparatus for securing two electrical connecting means together in a given relationship, one of said electrical connecting means being carried by a member having an outer annular groove at one end thereof. The latch comprises a housing body which carries the other of said electrical connecting means. The housing body has a forward end with space surrounded by an outer annular wall for receiving said one end of said member. An inner annular groove is formed in the inner portion of said wall at the forward end of said housing body. The outer portion of said wall at said forward end of said housing body has three angularly spaced apart axially extending grooves formed therein which intersect said inner annular groove forming three angularly spaced apart openings which expose said inner annular groove through said three angularly spaced apart axially extending grooves. An annular coiled spring is located in said inner annular groove. A sleeve is carried by said housing body for axial sliding movement between forward and rearward positions. Three angularly spaced apart arms extend from the forward end of said sleeve for sliding movement in said three angularly spaced apart axially extending grooves respectively. In the forward position of said sleeve, said arms force the portions of said annular coiled spring at said openings into said space at said forward end of said body and into said outer annular groove of said member for latching purposes.
