A strain relief system for a cable inserted within has a main housing with an opening and a series of ramp features and a series of serrations on an interior surface. The system also has a rotating collar with an opening in line with the opening of the main housing. The rotating collar having a series of follower features configured to be inserted into the opening of the main housing such that when the rotating collar is rotated relative to the main housing, the follower features engage the ramp features to compress the cable inserted with the strain relief system. The rotating collar also having at least one ratcheting tab configured to engage the series of serrations of the main housing such has to provide a ratcheting function between the rotating collar and the outer housing.

The present invention provides target devices such as filter units with at least one receiving channel with a stop surface that is electrically conductive and at least one cable with a connector assembly on a first end portion. The connector assembly includes a first member with an open channel. The first member is coupled to the end portion of the outer conductor with the free end of the inner conductor and the end portion of the dielectric extending through the open channel to reside forward of the first member. The first member resides in a respective one of the at least one receiving channel against the stop surface. The connector assembly also includes second member with an open channel The second member is slidably coupled to the first end portion of the at least one cable and presses the first member against the stop surface.

Various techniques are provided for displacing air from partial discharge sensitive regions of a connector of a low partial discharge high voltage connector to other regions of the low partial discharge high voltage connector where electrical flux is reduced. A plug member is mated with a receptacle member to provide the connector, with a seal member disposed in a cavity provided by the plug member and/or the receptacle member. In response to the mating, the seal member is compressed at an initial contact region between an innermost layer and an outermost layer of the seal member. In response to the compressing, air is forced radially inward toward the innermost layer and radially outward toward the outermost layer away from the initial contact region to reduce partial discharge associated with the connector. Additional methods and systems are also provided.

A torque sleeve includes sleeve body configured to extend along an axis. The sleeve body is further configured to at least partially receive a coupling member of a coaxial cable connector. The sleeve body has an outer surface configured to permit a user to tighten the coupling member to an interface port up to a first torque, and the sleeve body includes a pair of opposed cutouts configured to receive a tightening tool so as to permit the tightening tool to grip the coupling member and tighten the coupling member to an interface port up to a second torque, the second torque being greater than the first torque.
