A circuit breaking control unit receives an impact detection signal that is outputted from outside when an impact such as a crash of a motor vehicle has been detected, and generates and applies a circuit breaking control signal based on the impact detection signal. A circuit breaking unit forcibly interrupts a power supply path and stops the supply of power to a load. Therefore, the supply of power can be stopped immediately at the time the impact has been detected. In addition, a second load is a minimum electric system that is essential to cause the motor vehicle to travel. Therefore, even if the supply of power to the load is interrupted, the motor vehicle can be caused to travel. Hence, even at the time of an accident or the like, the motor vehicle can be moved to the edge of a road or the like with ease.

Power supply circuit breaking apparatus for motor vehicle and power

An arrangement and method for establishing an electrical and mechanical connection between electrically conductive members. The arrangement includes an electrically conductive connecting member, two electrically conductive metallic members disposed opposite each other, flanking the connecting member, and clamping the connecting member therebetween, and a source of laser energy oriented such that an output beam therefrom is incident on an outer surface of one of the metallic members and directed towards the underlying connecting member to establish a weld connection at zones of mutual contact between the connecting member and the respective metallic members. The connecting member includes a cable or the like and the metallic members include contact terminals, busbars or the like. In the method, the connecting member is positioned between the metallic members and the output beam is radiated on one of the metallic members in the direction of the connecting member so as to weld the connecting member to the metallic members.

Structure for welding electrical connecting portions to each other using

A connecting structure for the high voltage resistance wire used to feed a high voltage to, for instance, the ignition plug of an engine, has a high voltage resistance wire for noise suppression which has on one end a connecting terminal which can be fitted to a high voltage terminal that has a cylindrical insulator on its circumference. An insulating soft elastic cap is attached to the high voltage resistance wire and surrounds the connecting terminal, which is fitted to the high voltage terminal. The cap also is fitted to the cylindrical insulator of the high voltage terminal. A rigid holder is inserted on the outside of the elastic cap, and is fitted closely to the outer periphery of the connecting portion of the elastic cap and the cylindrical insulator.
