Abstract: In a detachable connector a socket assembly with a hollow body is provided. The inner walls of the hollow body define a cylindrical chamber having at least one opening. Also provided in the detachable connector is a pin assembly. The pin assembly includes a pin body attached to a cable sleeve having a groove extending throughout its circumference. The pin body is inserted into the open end of the socket assembly's chamber. A cylindrical metal contact sleeve is axially received in the chamber, the metal contact sleeve having axially spaced circumferential portions. These portions are constrained by the chamber wall. The metal contact sleeve also has detents that extend radially inward to engage the cable sleeve groove, when the pin body is received in the chamber.
