Provided is a metal core board which has a preferable function for a vehicle-mountable junction box, specifically, is reduced in size or improved in mounting efficiency. A metal core board for a vehicle-mountable junction box, which is mountable on the vehicle-mountable junction box, wherein a core plate forming an intermediate layer of the metal core board has a plurality of slits and an island surrounded by separating connection parts present between the slits; and in the state where the island is held between insulating layers stacked on both of two surfaces of the core plate, through-boresare formed at the separating connection parts to remove the separating connection parts and the island is made electrically independent from a remaining part of the core plate while being held between the insulating layers. Thus, a plurality of circuits can be formed.

It is an object to provide a configuration with an enhanced sensing accuracy, in which a shunt resistance main body and a terminal member are formed as separate pieces. A shunt resistor includes a resistance main body and a terminal member () that is electrically connected to the resistance main body. The terminal member () includes a resistance connection portion () to be in contact with the resistance main body, and a circuit connection portion () provided so as to extend from the resistance connection portion (). The circuit connection portion () is divided into two parts by a slit () being formed therein. The slit () is formed up to a part of the resistance connection portion ().

Connection terminal of shunt resistor, and battery state detection device

A method of connecting a flat cable having flat conductors arranged in parallel and covered with an insulating material to a connecting terminal, in which crimp pieces of the connecting terminal are pierced into a desired conductor of conductors of the flat cable, with a gap left between a substrate of the connecting terminal and the flat cable, and leading ends of the crimp pieces penetrating the flat cable are bent inwardly, while maintaining a contact position of the crimp pieces penetrating the conductor and the conductor unchanged. Also disclosed are an apparatus for embodying the connecting method and a method for determining a connecting state between the flat cable and the connecting terminal.

Method of connecting cable to connector

A method of connecting a flat cable and a terminal in which a flat cable comprising a flat conductor ( ) insulated with an insulation ( ) in the form of a tape and a terminal ( ) having a cramp piece ( ) are connected by sticking the cramp piece ( ) through the flat cable at a place corresponding to an intended portion of the flat conductor, and bending the cramp piece that has been stuck through the flat cable, toward the flat conductor to clamp the flat cable. An end portion of the cramp piece ( ) is made to project from the flat cable by a length that is in the range of 50&tilde;5% of the length of the cramp piece, and then the end portion of the cramp piece is bent.
