Heavy-duty electrical connector
First Claim
Patent Images
1. An electrical connector having plug and receptacle parts which are selectively joinable by rotation of a coupling ring, comprising:
- the coupling ring has a threaded bore which directly and continuously engages a complementary set of threads on an outer surface of the plug, and a flange which lockingly engages the receptacle during joining the connector parts;
means carried by and rotating with the coupling ring which contact further means carried by the plug preventing relative rotation of the coupling ring and plug beyond predetermined maxima; and
a layer of resilient insulative material carried by one of the connector parts which is compressed during joining of the connector parts, said layer having a predetermined thickness insuring layer compression throughout the full range of connector part manufacturing tolerances.

Abstract
To prevent possible misalignment of the various parts of a plug and receptacle connector, if the coupling ring is inadvertently rotated before the receptacle is in full position, there is provided an interlock sleeve. This sleeve is spring-loaded and positioned between the coupling ring and the plug outer surface. Internal and external keys incorporated within the sleeve prevent inadvertent rotation of the coupling ring until the receptacle has made entry into the plug sufficiently to key both the coupling ring and plug shell.

4. An electrical connector having plug and receptacle parts which are releasably mated by selective rotation of a coupling ring carried by said plug for interconnecting pin and socket contacts respectively mounted within said connector parts, comprising:
the coupling ring has a flange with at least one keyway formed therein aligned with a keyway formed in the plug when the plug is released from the receptacle, at which time spring-loaded means extend into the plug keyway obstructing rotation of the coupling ring with respect to the plug, and said spring-loaded means being movable from said coupling ring obstructing position to a further position allowing the coupling ring to rotate about the plug. - View Dependent Claims (5, 6, 7)
