A busbar module includes: busbars fixed to battery cells of a battery module; a plate-like flexible circuit body; and a case that accommodates the circuit body and the busbars, in which the circuit body includes a trunk portion extending in a first direction in which the battery cells are arranged, and branch portions branching from the trunk portion and connected to the busbars, the branch portion includes a base portion, a fixed portion fixed to the busbar, and an intermediate portion extending from the base portion to the fixed portion is the first direction, a first end portion of the trunk portion has a first through-hole, and the case includes a first protrusion and locks the first end portion with the first protrusion to hold the circuit body in a state where the intermediate portion is flexurally deformed.

The present disclosure provides a structural member for a vehicle. The structural member comprises a plurality of finned spar members interlocked with one another, wherein each finned spar member of the plurality of finned spar members includes a main body, a plurality of web members extending from a flange of the main body, a circuit board formed on the main body, and a bus bar comprising a tube positioned in an opening formed in the main body, the bus bar being in electrical communication with the circuit board, wherein a compartment is formed between adjacent web members, the compartment being sized to receive a battery.

A tap-off box includes a latch that automatically secures the tap-off box to a busway upon insertion of a mast into the busway. The latch is in the form of a single spring-loaded member that latches onto a rail as the masthead is pushed into the busway. A push button actuated camming member pushes the latch away from the rail to enable the masthead to be withdrawn from the busway. The push button and camming member are independent of the mechanism that extends and retracts the contacts while the masthead is inserted and latched into the busway. The tap-off box may also include non-contact current monitoring sensors with voltage sensing inserts that an auxiliary breaker switch in applications other than a tap-off box, and an infrared emitting faceplate that can be adapted for monitoring a variety of breakers from outside the tap-off box.

A unitary busbar provides power from one connection point in an electric vehicle to another connection point. The unitary busbar includes a central solid core conductor, an insulation layer over the solid core conductor, and an electromagnetic shield fitted around the insulator. The unitary busbar is capable of being bent into specific configurations that allow it to conform to the body of an electric vehicle.

An electrical connector for connecting a bus bar to a flexible conductor comprising a tubular conducting body having a first end adapted for lockably receiving an end of the flexible conductor and an opposite second end adapted for mounting a corresponding end of the bus bar therewith. The electrical connector is also provided with at least one resilient element operatively mounted with the second end of the tubular body and the corresponding end of the bus bar for maintaining the bus bar and the tubular body connected together.

A waterproof construction of a three-phase line part includes a three-phase line part having three bus bar construction bodies, a first terminal block provided on one end side of the three-phase line part, a second terminal block provided on the other end side of the three-phase line part, and a tubular exterior member that covers a middle portion of the three-phase line part. One end of the tubular exterior member is water-tightly fixed to a first housing of the first terminal block, and the other end thereof is water-tightly fixed to a second housing of the second terminal block, in a state that the tubular exterior member covers the three-phase line part.

An electrical device connector includes: a bus bar which includes a hollow portion extending in an axial direction and through holes extending in an axis-orthogonal direction, and which electrically connects a plurality of switchgears to each other; terminal members including bus bar support portions in which the bus bar is inserted, and including electrical device connection portions in which the insulation plugs are inserted and fixed; and stud bolts each having one end fixed to the corresponding switchgear, each extending in the axis-orthogonal direction through the corresponding through hole, and each fixing the corresponding insulation plug at the other end. Gaps are each formed between the corresponding stud bolt and the bus bar so as to allow communication between the hollow portion and an internal space of the corresponding terminal member.

A tap-off box includes a latch that automatically secures the tap-off box to a busway upon insertion of a mast into the busway. The latch is in the form of a single spring-loaded member that latches onto a rail as the masthead is pushed into the busway. A push button actuated camming member pushes the latch away from the rail to enable the masthead to be withdrawn from the busway. The push button and camming member are independent of the mechanism that extends and retracts the contacts while the masthead is inserted and latched into the busway. The tap-off box may also include non-contact current monitoring sensors with voltage sensing inserts that an auxiliary breaker switch in applications other than a tap-off box, and an infrared emitting faceplate that can be adapted for monitoring a variety of breakers from outside the tap-off box.

An electrical device connector includes: a bus bar which includes a hollow portion extending in an axial direction and through holes extending in an axis-orthogonal direction, and which electrically connects a plurality of switchgears to each other; terminal members including bus bar support portions in which the bus bar is inserted, and including electrical device connection portions in which the insulation plugs are inserted and fixed; and stud bolts each having one end fixed to the corresponding switchgear, each extending in the axis-orthogonal direction through the corresponding through hole, and each fixing the corresponding insulation plug at the other end. Gaps are each formed between the corresponding stud bolt and the bus bar so as to allow communication between the hollow portion and an internal space of the corresponding terminal member.
