A one-piece metallic connector is configured to receive a fastener and has features that grip and electrically bond two conductors as they are clamped together when the fastener is tightened. The connector's generally U-shaped body has first and second legs, a bight portion joining the legs and an opening in each leg through which a single mounting fastener can extend. When installed with the outside of one leg abutting one conductor, another conductor is clamped between the legs. At least one outer projection (tooth) on the outer face of one leg engages the conductor to which the connector is mounted. At least one inner projection (tooth) on the same leg engages the conductor clamped between the legs. A recess on the inner face of the distal portion of the other leg is configured to cradle the clamped conductor.

A terminal assembly for connecting a cable to a busbar includes a tubular body having a tubular portion disposed about a central axis and an annular end-wall. The tubular body defines an elongate recess configured to receive a free end of the cable therein. The terminal assembly also includes a fastener protruding outwardly from the annular end-wall. The fastener includes a first portion configured to be received within the tubular body and a second portion having a plurality of external threads thereon. The terminal assembly further includes a coupling member configured to couple the fastener with the busbar upon receipt of the second portion of the fastener within an opening in the busbar. The coupling member defining a plurality of internal threads that engage with the plurality of external threads on the second portion of the fastener to releasably secure the tubular body and the fastener with the busbar.

Rotary high-voltage and high-current connecting device has a plug and a socket. The socket has a connection unit, nut unit, insulating base, insulating cap, and contact protection cover. The plug has a connection unit, screw-like bolt unit, insulating base, and insulating cap. The nut unit is inserted into a concave structure of the socket insulating base. The socket connection unit is inserted into the insulating base and a copper sleeve is placed on the connection unit and the nut unit. Windows are provided on the insulating cap to lock with a detent structure of the socket insulating base. The contact protection cover is located on top of the nut unit. The insulating cap is joined with the plug insulating base via detent means and windows, while the plug is inserted into the socket by means of the nut unit and a bolt assembly.
