ABSTRACT:
A conical contact of a male plug is biased by a coil spring which rides on a cylindrical tail. A bushing compresses the spring, but is held captive on the tail by a pin passing radially through the bushing and a slot through the tail. A female receptacle has a conical hole to receive the conical contact. A sleeve extends from the hole, providing two ramp shaped slots to engage the protruding ends of the pin on the male plug. When the connector is mated, the bushing is inserted into the sleeve and the ends of the pin engage the slots in the sleeve, causing the conical contact to enter the conical hole. Rotation of the bushing causes the ends of the pin to ride the ramp shaped slots inward, causing the conical contact to rotate as the spring compresses, forcing the conical contact into the conical hole. When fully mated, the ends of the pin fall into detent positions at the ends of the slots, locking the connector. Biased by a spring, the matching tapers of the conical contact and conical hole provide a low-resistance, high-current non-compliant connection, while the detents lock the connector, eliminating accidental dis-connection.
