号公報参照）。2. Description of the Related Art Conventionally, various connectors have been used for connecting electric wires of wire harnesses of automobiles and the like, and various connecting structures of connectors and fixing structures of connecting terminals to connectors have been devised. Generally, a wire harness has a structure in which a branch electric wire is led out from a trunk line in which a large number of electric wires are bundled by tape winding, a connector is connected to the end of the branch electric wire, and is connected to a connector provided in various electric components. It has become so. In particular, since many switches and meters are concentrated on the instrument panel of automobiles, there are many connectors, so it takes a lot of labor and time to branch the wires from the wire harness trunk and connect them to the connectors. Moreover, a large occupied area is taken. Therefore, in order to reduce the number of connectors to be connected, a plurality of connectors are collectively made into a multi-pole, and a connecting method in which a connecting force required for connection is forcibly connected by a tightening bolt is generally adopted (Japanese Patent Laid-Open No. 62-62-62). 145672
