れ、トータルコストが低減できる利点がある。(Prior art and its problems) A conventional wire harness manufacturing method uses a splice fitting to connect a branch line of the same circuit system to a main line 41 of the same circuit system, for example, an electrical connection point 40a as shown in FIG. , 40
Branch at b and 40c, and connect from that branch line to connection points 40d and 4
It was common to connect in a branching manner with 0e and 40f, but recently, for many earth connections, wiper circuits, tail circuits, gauge circuits, etc., where there are many electrical connection points, a centralized joint using a junction connector is used. The method is being adopted. This method pulls out the insulated wire to be connected from the wire harness trunk line, strips the coating on the end of each insulated wire of the same circuit system, crimps the terminals, and mounts these terminals in the connector housing.
It is for connecting all at once with a junction bar (short-circuiting bus bar) (Actual No. 56-124984). Compared with the method using a splice fitting, this concentrated joint method does not require intermediate stripping of the main line and joints there, so that the assembly process of the wire harness can be simplified and the total cost can be reduced.

取り付け位置が制約されるという問題もある。However, the conventional wire harness manufacturing method that uses the central joint method uses a junction connector that is composed of parts such as a terminal, a connector housing, and a junction bar. In addition, since the junction connector is block-shaped and bulky, there is a problem in that the mounting position of the junction connector is restricted due to wiring.

Insulated electric wires are installed, the electrical connection points of the insulated electric wires are collectively installed between the electrodes of the welding machine, and the insulated electric wires collectively installed between the electrodes are collectively welded and connected. It is characterized in that the concentrated joint portion is formed by covering the connecting portion with an insulator.
