Patent ID: 7699651

Claim:
Co-axial plug and socket connector comprising: a co-axial plug and a bulkhead socket of the N type; the bulkhead socket having (a) an outer conductor including a cylindrical shell, (b) a co-axial cable end and (c) a mating end; an inside wall of the shell, adjacent the mating end, including a groove which extends round in an annular shape and which forms a latching edge; the co-axial plug comprising (a) an outer conductor including a cylindrical outer-conductor part of its shell and which has a mating end and a co-axial cable end, (b) a latching sleeve which fits round the outer-conductor part of the shell of the plug and is axially displaceable relative to the outer-conductor part of the shell of the plug, a spring having a first end bearing against the outer-conductor part of the shell of the plug and a second end bearing against the latching sleeve so the latching sleeve is pre-loaded in the direction of the co-axial cable end of the outer-conductor part of the shell, the latching sleeve having axial slots at its mating end so that elastically resilient latching tongues are formed, said latching tongues each having, at their mating ends, a latching edge which extends in a radially outward direction, to latch onto the latching edge of the groove in the bulkhead socket, and an unlocking sleeve surrounding the latching sleeve and displaceable axially relative to the latching sleeve, the latching sleeve having a ramp which slopes in a radially outward direction toward the co-axial cable end, the ramp co-operating with a correspondingly beveled groove on an inside face of the unlocking sleeve so that displacement of the unlocking sleeve relative to the latching sleeve in the direction of the co-axial cable end causes the latching tongues of the latching sleeve to bend radially inward.
