A tap plug for engaging a conductor lug and a stud is provided. The tap plug includes a housing, a first member, and a second member. The housing has an inner bore defining a longitudinal axis. The first member is in the inner bore and is rotatable with respect to the housing about the longitudinal axis. The first member has an external thread at a first end, where the external thread engages the conductor lug. The second member is rotatable with respect to the housing about the longitudinal axis and has an internal thread at the first end. The first end is open so that the internal thread can engage the stud.

A cable connector relates to a field of cable connecting technology. The cable connector includes a main body assembly including an insulating main body and conductive main bodies, a first clamping assembly, and a second clamping assembly. The conductive main bodies are disposed on the insulating main body. Two ends of each of the conductive main bodies extend outwards from bottom portions of the first accommodating groove and the second accommodating groove. The two ends of each of the conductive main bodies are sharp structures. The first clamping assembly includes a first clamping piece movably disposed up and down in the first accommodating groove and a first operating piece disposed on the insulating main body. The second clamping assembly includes a second clamping piece movably disposed up and down in the second accommodating groove and a second operating piece disposed on the insulating main body.

An adaptor is provided for connecting an electrical cable with an electrical connector. The adaptor includes a housing and an insert which are coaxially arranged and connected for free rotation relative to each other. The outer surface of the insert contains an annular recess and at least one pin is arranged on an inner surface of the housing. When a portion of the insert including the recess is arranged within a portion of the housing, the pin is inserted into the recess to connect the insert with the housing while permitting rotation therebetween. The free rotation prevent torque from being transmitted to an electrical cable connected with the insert.

A connector used in underwater environments includes a male connector with a sensing terminal and two power terminals, a female connector with a sensing terminal block and two power terminal blocks, and an elastic gasket set between the male connector and the female connector. When the male connector and the female connector are plugged into each other, and the male and female connectors squeeze the elastic gasket to form a large amount of deformation, the sensing terminal and the sensing terminal block are in contact with each other. When the male and female connectors squeeze the elastic gasket to form a small deformation state, the sensing terminal and the sensing terminal block are separated from each other, and the power terminals and the power terminal blocks are in contact with each other, thereby forming a waterproof protection mechanism.

A motor lead coupler is configured to provide a metal-to-metal sealed connection between a first motor lead extension and a second motor lead extension. The motor lead coupler includes a first plurality of receivers on a first end of the body, a second plurality of receivers on a second end of the body, and a plurality of intermediate terminals. Each of the first plurality of receivers is configured to receive a corresponding one of the first plurality of leads, and each of the second plurality of receivers is configured to receive a corresponding one of the second plurality of leads. Each of the intermediate terminals is connected between a corresponding pair of the first plurality of receivers and the second plurality of receivers. The motor lead coupler includes pressure test ports that can be used to pressure test the connection between individual leads and the motor lead coupler.
