ていた。<Prior art> A large number of wire connection methods have been widely used in which a large number of electric wires that have been fitted with conductive terminals are collectively attached to a pair of male and female connectors, and the electric connection between the plurality of electric wires can be made simultaneously. ing. In addition, it is often necessary to connect many wires in a complicated state. In these cases, it is widely practiced that some sort of mark is attached to the end of each wire as an identification means for preventing mistakes in the wire connection work, but in the past it was mostly manual work, so a huge number of wires were used. The attachment of the identification tool to the end of the wire was extremely complicated and inefficient.

ることができる。<Effects of the Invention> According to the present invention, the protrusion of the length corresponding to the cylindrical portion of the conductive terminal crimped to the end of the wire and having a shape capable of surrounding the entire circumference is the plate shape of the wire identification indicator. Since it is projected from the main body, the end of the wire to which the indicator is attached can be flexed freely outside the protrusion, which is convenient not only for the operation during the attaching work but also for the attaching operation. It is easy to arrange the rear end of the wire and electrical equipment, and since the cylindrical part is almost completely covered, there is no risk of accidental electric shock, and moreover, it is necessary between the tip edges of the projecting pieces. A wide cutout area is formed on at least one end side of the clearance despite the provision of the minimum thin clearance. Therefore, the tip of the protruding piece expanding jig used for mounting the display tool. Can be easily inserted and a force exceeding the above-mentioned certain limit can be applied. With, it is possible to attach the indicator to the end of the electric wire accurately and quickly.
