Abstract: A coaxial plug and socket connector includes a coaxial plug and a bulkhead socket. The socket has: an outer conductor shell, and coaxial cable and mating ends. The shell inside wall, adjacent the mating end, has a latching edge groove. The plug has: an outer conductor shell having mating and coaxial cable ends, a latching sleeve fitting round and axially displaceable relative to the plug shell. The latching sleeve has axial slots at its mating end forming elastically resilient latching tongues having, at their mating ends, a latching edge extending radially outwardly to latch onto the socket groove latching edge. An unlocking sleeve surrounding and displaceable axially relative to the latching sleeve has a ramp sloping radially outwardly toward the cable end. The ramp cooperates with a groove on an inside face of the unlocking sleeve so unlocking sleeve displacement relative to the latching sleeve bends the tongues inwardly.

Abstract: A co-axial plug has a cylindrical outer-conductor part having mating co-axial cable ends. A latching sleeve fits around and is axially displaceable relative to the shell outer-conductor. Opposite ends of a spring are supported against the shell outer-conductor part and the latching sleeve to pre-load the latching sleeve toward the co-axial cable end of the shell outer-conductor part. Axial slots at the latching sleeve mating end form elastically resilient latching tongues having, at their ends, a latching edge extending in a radially outward direction. An unlocking sleeve surrounding the latching sleeve is displaceable axially relative to the latching sleeve having a ramp extending outwardly and sloping toward the cable end. The ramp co-operates with a correspondingly bevelled groove on the unlocking sleeve inside face so displacement of the unlocking sleeve relative to the latching sleeve toward the co-axial cable end bends the latching tongues inwardly.
