A terminal and a central electrical box are disclosed. The terminal is used to be mounted on a circuit board. The terminal comprises: a first termination part; a second termination part; and a bending part connected between the first termination part and the second termination part. The bending part is bent by a predetermined angle relative to the first termination part and the second termination part, so that the first termination part and the second termination part are staggered by a predetermined distance along a direction transverse to a direction of inserting the terminal to the circuit board. When the terminal is mounted on the circuit board, one of the first termination part and the second termination part passes through the circuit board. In the present invention, the terminal passes through the circuit board, so that two electronic devices located on both sides of the circuit board can be directly electrically connected through the terminal. Therefore, the number of terminals is reduced, and there is no need to set wiring for electrically connecting the terminals on the circuit board, which greatly reduces the cost.

A protection relay device includes a housing and a fuse unit. The fuse unit includes a connection conductor, an input conductor connected to the connection conductor and receiving an external power, a fuse connected to the connection conductor, and an external device connection conductor connected to the fuse on a side opposite to the input conductor, and to which an external device is connected. A short-circuit induction conductor is provided on at least one of the input conductor on a side opposite to the fuse and the flapper portion, the short-circuit induction conductor protruding toward the other of the input conductor and the flapper portion.

A fuse includes a housing. A bus bar extends through the housing. An arc interrupter positioned inside the housing. A biasing element is compressed between the housing and the arc interrupter to bias the arc interrupter toward the bus bar to separate two portions of the bus bar during circuit interruption to mitigate arcing from one portion of the bus bar to the other portion of the bus bar. The bus bar includes a pocket defined therein wherein the bus bar is of a first material, and wherein a second material is seated within the pocket. In another aspect, a fuse includes a fuse housing and a bus bar extending through the housing. The bus bar includes a pocket defined therein. The bus bar is of a first material, wherein a second material is seated within the pocket.

A frangible shunt link assembly includes a frangible link configured to conductively couple a current collector coupled with a vehicle and one or more components of the vehicle. The frangible link is configured to break responsive to the current collector being at least partially separated from the vehicle to interrupt a conductive connection between the current collector and the one or more components of the vehicle.

A fuse box for a battery of a vehicle includes: a lower housing having a space in which a fuse is housed and a bus bar for electrically connecting the battery and the fuse is seated; a plate-shaped upper housing having a through hole formed at a central portion thereof and a first extending portion extending upward along a circumference of the through hole, where the upper housing is assembled on an upper side of the lower housing; and a fuse cover that is coupled to an upper side of the upper housing to cover the fuse exposed through the through hole of the upper housing.

A wiring module to be attached to a plurality of power elements which store or generate power includes a bus bar connecting the power elements to each other or connecting the power element and a load to each other, an abnormality detection element detecting an abnormality of the power element, and an insulating protector holding the bus bar and the abnormality detection element. The insulating protector is integrally provided with a first holding shaft portion and a second holding shaft portion which position and hold the bus bar by fitting the bus bar there onto, and an element holding portion which position and hold the abnormality detection element by fitting the abnormality detection element there into.

Flat surfaces out of two flat surfaces of each of flat electrical connection bodies of a relay bus bar and a bus bar of an electronic component are mating surfaces brought into contact with each other by a fixing structure. At least one of the flat electrical connection bodies of the relay bus bar and the bus bar applies a reaction force accompanying the elastic deformation to the other flat electrical connection body, to which the one flat electrical connection body is to be connected, in a state in which the flat electrical connection body of the bus bar at an accommodation completion position in a housing has not been connected to the relay bus bar. The housing includes a receiving portion receiving a force applied to the flat electrical connection body of the bus bar from the flat electrical connection body of the relay bus bar.

A jumper bus bar may include a frame and a terminal assembly. The frame is to be seated along a surface of a housing of an electrical box. The terminal assembly features a first fork terminal perpendicular to the frame and a second fork terminal perpendicular to the frame. The first fork terminal is adjacent the second fork terminal. The terminal assembly also includes a slot to receive a terminal of a fuse or relay, the slot being coplanar with the frame.

Provided is an electrical connection box including a housing casing for housing a relay, and a heat transfer sheet for transferring heat from the relay to the housing casing, the electrical connection box including: a bus bar provided between a top surface and an inside surface that correspond to each other in the housing casing so as to oppose the top surface and the inside surface; a first holding portion protruding from the inside surface and holding the bus bar via the heat transfer sheet; and a second holding portion protruding from the top surface and holding the bus bar.

A fuse module including a housing, a busbar disposed within the housing adjacent an interior surface of a rear wall of the housing, a terminal extending through a front wall of the housing and having a fuse coupling portion disposed within the housing adjacent an interior surface of a front wall of the housing and a conductor coupling portion protruding from an exterior surface of the front wall of the housing, and a movable pushrod extending through the rear wall of the housing and having a head portion disposed adjacent a rigid portion of the busbar for moving the rigid portion of the busbar between a retracted position, the rigid portion of the busbar located near the interior surface of the rear wall, and an extended position wherein the rigid portion of the busbar is located further from the interior surface of the rear wall relative to the retracted position.
