An electrical connector is disclosed which is particularly adapted to electrically and mechanically connect a main conductor to a bail or tap conductor. The connector includes a C-shaped frame having a curved top wall adapted to fit over a main conductor and a curved bottom wall adapted to receive a bail or tap conductor. A fastener-operated wedge assembly is carried within the frame between a conductor receiving position and a conductor clamping position. The wedge assembly has a wedge body with a primary contact surface adapted to contact the main conductor and a secondary contact surface adapted to contact the bail or tap conductor when the wedge body is moved from the conductor receiving position to the conductor clamping position. The fastener positively moves the wedge body between the positions so that the clamping action of the connector can be tightened or loosened as desired. A head portion of the fastener may include a breakaway feature to help prevent over tightening of the fastener.

A circuit structure includes: an upper case having positioning holes; bus bars that are provided in an inductor disposed in the upper case and that have through holes; terminals that are connected to electric wires and that have bolts disposed thereon that penetrate the through holes; nuts that sandwich the bus bars between the nuts and the terminals by being screwed onto the bolts; and a lower case that is attached to the upper case. The lower case includes: front walls, left walls, and right walls that project upward from the lower case and position the terminals relative to the lower case by coming into contact with the terminals; and case positioning portions that project upward from the lower case and that are inserted into the positioning holes.

A plug-in device and a power conversion apparatus are provided. The plug-in device includes a housing, a connector and a temperature acquisition device. The housing is defined with a holding cavity. The connector includes a clamping part and a fixed connection part. The clamping part is arranged in the holding cavity. The fixed connection part partially extends out of the housing. The clamping part is configured to clamp a power conversion device. The fixed connection part is connected to a reactor. The temperature acquisition device is arranged close to the connector, and is configured to acquire a temperature at an overlapping point of the power conversion device and the clamping part.

A cap (50) is mounted on a housing (22) for accommodating a device-side terminal connected to equipment and a wire-side terminal connected to a wire, the housing (22) being formed with a second opening (228) for exposing a connected part of the device-side terminal and the wire-side terminal, and is provided with a cap body (51) for closing the second opening (228) of the housing (22), locking portions (52) to be locked to outer side surfaces of the housing (22), and protection walls (53) for covering the locking portions (52) while being spaced apart from the locking portions (52).

A terminal clamp cover device for low voltage circuit breakers, in particular for molded case circuit breakers, having one or more phases, each provided with a terminal for the electrical connection of the circuit breaker, a clamp for the connection of the terminal to an electrical circuit and a vent opening to discharge the gases produced in the circuit breaker during opening/closing operations. The device includes an insulating body that covers the clamp, the insulating body being provided on at least one portion of its outer surface with a plurality of heat dissipating elements. A low voltage circuit breaker, in particular a low voltage molded case circuit breaker, including a device of the type described also forms part of the application.

A device assembly capable of selectively bonding one or more tracer wires to ground and isolating the one or more tracer wires from ground is provided. The device assembly includes a housing, an electrical switch within the housing and one or more contact assemblies. The one or more tracer wires and ground wire are connected to the one or more contact assemblies. The electrical switch can connect the tracer wires to the ground wire and can isolate the tracer wires from the ground wire.

An electrical contact for forming a materially bonded, electrically conductive connection to a mating contact comprises a contact surface and a soldering body. The contact surface has a recess extending into the contact surface. The soldering body is formed of a hard solder material and is pressed into the recess. The soldering body protrudes out from the recess beyond the contact surface.
