[0002]

2. Description of the Related Art Conventionally, among wire harnesses for electrically connecting electrical devices, for example, wires connected to the ground and wires using a common electrical signal are connected to the same terminal of the electrical device. Since it is inappropriate to perform the connection, only one electric wire is connected to the terminal of the electric device by conducting the electric current on the way.

As shown in FIG. 6, for example, as shown in FIG. 6, the electrical connection between the electric wires is performed by stripping the cover of the electric wire E and crimping the splice terminal 1 to the core wire C, and then winding the tape 2 to obtain insulation. As shown in FIG. 7, the plurality of press-connecting blades 3a of the conductive plate (short-circuit member) 3 are not
In this case, the core wire C is pressed into contact with the core wire C to make it conductive, and then housed in a resin case 4 to maintain the pressure-contact state together with insulation.
