In this conventional example, the round electric wires, which are processed one by one, are arranged in parallel in parallel at intervals, and the fixing tape is post-processed in the vicinity of the ends of the parallel-arranged circular electric wires. This is a terminal processing method in which the end processing of the electric wire is offset from the insulating coating portion, and the circular electric wires are fixed while maintaining the distance between them (hereinafter referred to as prior art 2).

The insulating coating 11 is removed by the processing rule 3 at a portion where a length required for connection is left from the end portion of the round electric wire 1 in which the insulating coating 11 is applied to the conductor 4 and the conductor 4 is stripped (see FIG. 3a). , B,
c).

A plurality of round electric wires 1 subjected to terminal processing, in this conventional example, three are arranged in parallel in parallel at an interval (Fig. 3d), and each round electric wire 1 is commonly and collectively Then, the fixing tape 2 is attached and fixed at a position displaced from the end of the insulating coating 11 at the end of the round electric wire 1 in a state in which the distance is maintained, and a flat electric wire having an end processed is formed (third embodiment). Figure e).

The present invention solves the problems of the prior art, accurately and stably sets the displacement dimension between the insulating coating and the fixing tape at the ends of a plurality of round electric wires forming a flat electric wire, and facilitates processing. This method provides a flat wire end-processing method that is performed in step 1. Cut the round electric wires that are arranged in parallel with each other,
In the method for processing the connecting end of the flat electric wire, the insulating end of the round electric wire at the cut end is peeled off to form the connecting end, and the connecting end of the flat electric wire is formed. In the vicinity of the cut section of the round wire, the cut section is sandwiched, and fixing tapes are attached at two locations separated by the length required for connection to fix the round wire at a parallel arrangement interval. It is characterized in that it comprises a step of cutting round electric wires arranged in parallel in an intermediate portion between fixing tapes attached to the locations, peeling off the insulating coating at the cut end of the cut round electric wires, and stripping the conductor. And

[Action]

INDUSTRIAL APPLICABILITY The present invention provides a connection end processing for a flat electric wire in which a plurality of round electric wires arranged in parallel at a set interval are partially fixed and a fixing tape is affixed collectively. When doing, sandwich the cut part of the round electric wire that forms the connection end, and attach the fixing tape to the two locations on both sides that are separated by the length required for the connection to maintain the parallel arrangement interval of the round electric wires. After fixing, the round wire is cut, the insulation coating is peeled off, and the conductor is stripped off. On the other hand, since it is fixed with a fixing tape with a necessary shift, the terminal processing by cutting the round electric wire and peeling the insulating coating can be easily performed with high dimensional accuracy. Embodiments will be described below with reference to the drawings.
