A pre-fuse assembly designed to protect certain components within a vehicle electrical system against short circuits and to provide a user with easy access to a jump post for jump starting a dead battery. The pre-fuse assembly is a current-limiting electrical device that is mounted on top of the vehicle battery and includes fuses for limiting the current from the vehicle battery to a power distribution device and includes a horizontal jump post for providing easy access when jump starting a dead battery without increasing the overall height of the device. In one embodiment, the pre-fuse assembly includes a lower housing, an upper housing, a battery post connector, a master fuse, a fastener, a horizontal jump post and any number of other components.

An insulative fixing plate damaged when overheating limits two conductive elements from contacting with each other, forming a closed path, when overheating, opening two conductive elements by an elastic force to form an open circuit. Each conductive element has a groove concaved in from an edge, and the groove has a groove width. The insulative fixing plate includes a connecting element and two limiting elements combined at two ends of the connecting element. Each limiting element has a working width larger than the groove width, and a holding space between the two limiting elements contains the two conductive elements, thereby abutting the two limiting elements at an external side of the conductive element respectively and limiting the two conductive elements from contacting with each other. The connecting element is damaged when overheating. The insulative fixing plate is used in overheat protection for a plug or a socket.

The present invention refers to a busbar for electrically connecting a plurality of cells of a battery module. In order to electrically disconnect the battery cells from each other upon thermal runaway of at least one of the cells or short circuit, the busbar includes a core and a shell at least partially made of a first material, said first material being an electrically conducting material, wherein the core is at least partially made of a second material having a coefficient of thermal expansion which is significantly higher than the coefficient of thermal expansion of the first material.

An electric connector includes a socket connector, a bar-like plug connector to be inserted/withdrawn to/from the socket connector and a fuse. When the plug connector is inserted to the socket connector, electric conduction is established in the electric circuit via the fuse. The fuse is attached to the socket connector.

A connector with protection mechanism may include a first connector, and the first connector has a first terminal, a second terminal, and a protector. The first terminal and the second terminal respectively serve as positive and negative electrodes, and the protector is electrically connected to the first terminal or the second terminal. An indicator light is electrically connected between the first terminal and the second terminal, and when the first connector is in a conductive state, the indicator light lights up. A connector socket is sleeved outside of the first terminal and the second terminal, and the first terminal, the second terminal, the protector, the indicator light, and the connector socket are further covered by a connector sleeve to insulate and conceal the wiring, ensuring the protector is securely enclosed within the connector sleeve.

A fuse unit 10 includes: a first terminal portion 21 to be connected to a bus bar 70; a second terminal portion 31 to be connected to an electric wire 60; a melting portion 41 that connects the first terminal portion 21 and the second terminal portion 31 to each other and is configured to melt due to overcurrent; and a case 50 covering the melting portion 41. The first terminal portion 21 includes a first connection portion 24 having a contact surface 24A that is to come into contact with the bus bar 70, and a first holding portion 23 that is arranged between the first connection portion 24 and the melting portion 41 and is held by the case 50. The second terminal portion 31 includes a second connection portion 34 to be connected to the electric wire 60, and a second holding portion 33 that is arranged between the second connection portion 34 and the melting portion 41 and is held by the case 50.

Techniques and apparatuses for forming electrical connection are presented in which an apparatus may include an in-line fuse having terminals comprising terminal exterior surfaces and terminal recesses, and electrical cables comprising a conductor and a insulation sleeve and having an exposed portion and an unexposed portion. The exposed portion of an electrical cable is at least partially inserted into a respective terminal recess of the in-line fuse. The apparatus may further comprise one or more temperature-activated sealing members that circumferentially surround and form a seal against portions of the terminal exterior surfaces of the in-line fuse and portions of the insulation sleeves of the electrical cables. The apparatus may also comprise an inner mold encapsulating the in-line fuse and at least partially of the one or more temperature-activated sealing members, and an outer mold encapsulating the inner mold.
