A bayonet-type lock arrangement in an electrical assembly for resisting unwanted rotation of a coupling member when a pair of connector members (10, 20) are in metal-to-metal contact, the lock arrangement including a one piece lock ring (56) having three cams (58) with each cam being disposed in the terminus of one of the helical grooves and each including a cam surface (58c) and an abutment shoulder (58d), a locator key (60) on the lock ring being received in an axial keyway (62) of the coupling member to maintain each cam in its respective terminus (53), and a waved washer (52) biasing the lock ring forwardly, each of the bayonet pins (18) passing over the respective cam surfaces being captivated and prevented by the respective abutment shoulders from uncoupling rotation.

An electrical connector assembly comprising first and second connector members, a coupling member rotatably mounted to said first connector member for connecting to the second connector member to cause a portion of said first connector member to abut a portion of said second connector member, one and the other said second connector member and said coupling member including, respectively, a radially extending bayonet pin and a wall provided with a helical groove arranged to be threadably engaged by the pin for pulling the connector members together into mated relation upon rotation of the coupling member in one direction, said helical groove having an entrance port for receiving the pin and spiralling axially rearward from the port to its terminus, and locking means for locking the mated assembly together by restraining said coupling member against unwanted rotation in the other direction, said locking means being characterized by a cylindrical lock ring disposed in a plane perpendicular to the axis of rotation and in a clearance fit about said first connector member for axially sliding movement thereto, said lock ring having a top and a bottom surface and a shoulder, said shoulder being normally free from engagement with said bayonet pin and extending longitudinally forward from the top surface and into the terminus for captivating said bayonet pin when the pin is advanced thereto; locator means for constantly locating the shoulder adjacent to the terminus; and bias means acting against the bottom surface for biasing the lock ring axially towards said helical groove.
