Abstract

PURPOSE:To prevent the occurrence of the alignment disturbance of round type electric wires by depositing and fixing a fixing tape with ears longer than positions of round type electric wires aligned on outsides left by 10mm or more at end sections of the round electric wires aligned in parallel to form a flat type multi-core electric cable, cutting off the ears of the fixing tape, and performing the terminal processing. CONSTITUTION:A fixing tape 14 is continuously fed from a tape depositing section 4, it is deposited and fixed with ears 18 longer than the position of the round type electric wires 15 aligned on outsides left by at least 10mm or more to form a flat type multi-core electric cable. The ears of the fixing tape 14 are then cut off, end sections of the round type electric wires forming the flat type multi-core electric cable are fed to a cutting and peeling section 6 to perform the terminal processing. The occurrence of the alignment disturbance of the round type electric wires 15 due to the insufficient deposition of the fixing tape 14 can be prevented.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention involves arranging a plurality of round electric wires in parallel with a distance between them, and fixing the distance between the round electric wires at the terminal portion using a fixing tape. The present invention relates to a method of manufacturing a fixed flat multicore electric wire.

[Conventional technology]

Demand for flat multicore electric wires is increasing in wiring for electrical and electronic devices due to space factor issues and rationalization of wiring work.

Conventionally, in this type of flat multicore electric wire, the distance between the electric wire conductors arranged in parallel is determined and fixed by a common insulating coating layer over the entire length. By the way, when actually used for wiring, it is only the terminal part that requires lining up multiple wires at a predetermined interval, so after cutting the multiple wires to the required length, each Attempts have also been made to use wiring in which the terminals are lined up at predetermined intervals and a fixing tape is applied to only the terminal portions so that they are fixed together.

[Problem that the invention seeks to solve]

The conventional wiring method involves arranging multiple wire ends at predetermined intervals and attaching fixing tape only to the ends to fix the wires in one piece.After cutting the wires to a predetermined length, the intervals are fixed at the end parts. In order to fuse the tape for use with wires, it is common to manually cut the wires, peel off the insulation coating, arrange them in parallel, and apply and fuse the fixing tape, which poses operational problems. In addition, with conventional flat multicore wires that have a common insulating coating layer over their entire length, in addition to the inconvenience of wiring, the terminals require manual labor to remove the coating and expose bare conductors.
I have a work problem. In particular, round electric wires are lined up in parallel at predetermined intervals and fixed tape is fused to them, and then they are cut to the required length and the insulating coating layer at the end of the round electric wires is peeled off to form the conductor. When attempting to include the process of exposing the terminals in a series of manufacturing method steps, fixing tape is fused to the ends of the round electric wires arranged in parallel, and at the same time, the ends of the round electric wires arranged on the outside are When cutting the fixing tape that is continuously supplied with dimensions that are just around the corner on both sides, due to the force applied during cutting, the round electric wires on both outside sides are not sufficiently fused to the fixing tape, and the arrangement of the round electric wires is interrupted. There is a problem in that it causes disturbance.

[Means for solving problems]

The present invention solves the conventional problems, arranges round electric wires in parallel at predetermined intervals, and stably and easily connects the terminal ends without causing disorder in the arrangement of the round electric wires due to insufficient fusion of the fixing tape. The present invention provides a method for manufacturing a flat multicore electric wire in which the connecting ends of each fixed round electric wire are integrally fixed, and the insulation coating is peeled off to expose the wire conductor.
A plurality of round electric wires are supplied from a core supply, and after passing the round electric wires through a batten, they are arranged in parallel while maintaining a distance from each other through a wire straightening section, and the round electric wires arranged in parallel are In the method for manufacturing a flat multi-core electric wire, which comprises a step of fixing the distance between the ends of the electric wires with a fixing tape supplied from the tape fusion part, the distance between the ends of the plurality of round electric wires arranged in parallel. The process of forming a flat multi-core electric wire by fixing with a fixing tape supplied from a tape fusion section involves continuously supplying the fixing tape from the tape fusion section, and fixing the continuously supplied fixing tape. at least 10 points away from the position of the round wires arranged on the outside at the end of the round wires arranged in parallel.
After cutting the ends of the round electric wires arranged in parallel to each other by leaving a selvage of 1 mm or more in length, and fusing and fixing the ends of the round electric wires with the selvedges remaining, a long portion remains from the position of the outer round electric wire. The edges of the fixing tape are cut to form a flat multi-core electric wire, and the ends of the flat multi-core electric wire are cut to a predetermined length by a cutting and peeling section equipped with a fusion tape adjustment cutter. The present invention is characterized in that it includes a step of peeling off the insulation coating layer of the round electric wire at the end of the cut flat multicore electric wire to expose the conductor of the round electric wire.

[For production]

In the method for manufacturing a flat multi-core electric wire of the present invention, a flat multi-core electric wire is formed by fixing the mutual spacing between the ends of a plurality of round electric wires arranged in parallel with a fixing tape supplied from a tape fusion part. In this process, the fixing tape is continuously supplied from the tape fusion part, leaving an edge at least 10 mm longer than the position of the round wires arranged on the outside at the ends of the round wires arranged in parallel. After fusing and fixing in a long state to form a flat multi-core electric wire, the ears of the fixing tape are cut, and the end of the light wall electric wire forming the flat multi-core electric wire is sent to the cutting and peeling section, and the terminal is removed. Since this is a processing process, there is no chance of the round wires being arranged out of order due to insufficient fusion of the fixing tape.
A flat multi-core electric wire can be manufactured stably and easily.

Examples will be described below based on the drawings.
