  • Circuit protecting device for an automotive wiring harness
    Patent number: 5731944
    Abstract: A circuit protecting device for an automotive wiring harness designed to make the dimensions of wires downstream from fuses smaller and minimize the number of circuits which will be brought into an inoperative state upon blowout of a fuse resulting from a short circuit which occurs in a wire by supplying protecting circuits for supplying power from a power source to loads with fuses provided in the circuits connected in one-to-one relationship with the loads so that, upon blowout of one fuse, only a power supply to the load connected with this fuse is cut off. The fuses are formed by a flat fuse 20 including a plurality of conductive fusible elements 21 arranged at specified intervals on the surface of an insulating plate 22.
