There are many known examples such as No. 17 and Utility Model Application No. 63-194413, etc., and the basic structure thereof is as shown in Figs. The coating at the end of the wire group is peeled off to expose a slightly longer conductor 1, and the coated portion of the wire group along the base of the exposed conductor 1 is

れている。[0003]The above-mentioned flat multi-core electric wire is manufactured by cutting the electric wires individually to the required length and performing a primary process of peeling off the coating at both ends. Alternatively, the individually cut wires may be arranged in a parallel plate-like state by hand, and the coverings of the ends of the wires in the arranged state may be peeled off. A manufacturing method is adopted in which a connecting tape 23 is attached and finished.

量産高生産性の要件に欠ける難点がある。[Problems to be Solved by the Invention] In the above-described conventional manufacturing method for flat multi-core electric wires, there is no continuity in the processing steps from wire cutting to finishing, and furthermore, the coating is removed from the ends of each wire individually. In addition, since the attachment of the connecting tape is done manually, it requires a lot of processing time and man-hours, resulting in low productivity, which is disadvantageous in that it does not meet the requirements for high productivity in mass production in recent years.

点がある。Furthermore, since the above-mentioned conventional manufacturing method uses a knife cutter to peel off the coating, it is easy to cause irregular shapes of exposed conductor groups and damage to the conductors due to excessive or insufficient cuts in the coating, and the connecting tape is applied manually. Due to uneven work,
Inadequate adhesion may cause the exposed conductor to have a poor posture.Furthermore, the contact portion 8 may buckle or bend due to insufficient rigidity of the group of exposed conductors, resulting in poor contact with the other party, which is a quality problem. On the other hand, stranded wire conductors, which have low rigidity and easily cause strands to come loose, are not used in flat multicore wires, so the overall flexibility of the flat multicore wire is poor, and it is difficult to arrange quadratic curves. There is a drawback in that the movable wiring is not adaptable to bending during use.

And, the intermediate skin stripping process does not use a cutting knife,
In addition, since the coating removal length can be set depending on the heating length and the position of the blade, the precision of the intermediate skin removal part is good, and there is no risk of damage to the conductor.

せることができる。Furthermore, in the method for fixing an adhesive tape and a conductor according to the third invention, the fusible metal layer applied to the conductor is heated above its melting point and comes into contact with the adhesive tape of the insulating film together with the conductor. The adhesive tape at the contact area also melts due to the heat of the conductor, and the molten metal that melts and flows down under its own weight is bonded to the molten adhesive tape, so the molten metal may flow into the recesses of the adhesive tape, or the molten metal may The molten adhesive tape bites into each other like a saw blade, and as it cools and solidifies, it produces the so-called anchoring effect (also known as the fastener effect), and the cooling and solidifying adhesive tape of the conductor and insulating film is extremely strong. This makes the parallel posture of the exposed conductors extremely stable, and the fusible metal also adheres between the strands of the stranded conductor, preventing the strands from coming apart. Therefore, by using this fixing method, the mechanical properties of the contact portion made of stranded wire conductors are improved, making it possible to use stranded wire conductors and improving the flexibility of flat multicore electric wires. .

Since the exposed upper flat portion becomes a contact surface with the other party, electrical connectivity is improved and insertion into the other party is facilitated.

時加工する。Next, the intermediate skin stripping section 4 is divided into a pre-treatment section 9 for heating the coating and a post-treatment section 10 for stripping the heated portion. That is, see FIG. 2, preprocessing section 9
A heating plate 16 with temperature adjustment, which corresponds to a heating jig, is provided above the stand 18 so as to be able to rise and fall freely. The conductor 1 has a structure in which the coating at the designated peeling portion is heated and softened and pushed down to form an exposed portion 17 in which the conductor 1 is partially exposed. and,
The post-processing section 10 has a pair of clamps 15 that lie down and hold the electric wire 2 fed from the pre-processing section 9, and a wire holding plate 14 between the clamps 15, and an exposed portion of the electric wire 2 clamped by the clamp 15. A pair of notching and peeling blades 13 are set symmetrically below both ends of the exposed portion 17, and the pair of notching and peeling blades 13 advance simultaneously to cover the lower half portions of both ends of the exposed portion 17. After making the cut, they move close to each other as shown by the dotted lines in the figure, and during the approaching action, the covering of the exposed part 17 is pinched and pressed from both ends of the cut, and the pinching and pressing causes the exposed part 17 to close together. The structure is such that the coating is peeled off to form an intermediate skin peeling part 20 in which the entire circumference of the conductor in the exposed part 17 is exposed. In addition, for cutting and peeling, the peeled coating (covering waste) held by 13 is
By opening the incision and peeling blade 13, it is caused to fall by gravity. Further, the incision/stripping blade 13 has U-shaped groove cutting edges that cut into individual coatings of the electric wires 2, and processes a group of electric wires at the same time.

Processing is done. That is, in the preprocessing section 9, as shown in FIG.
For reference, a hot plate 16 having approximately the same length as the coating peeling length is heated to about 300° C. to press and heat the upper end of the electric wire 2 in the axial direction supplied to the stand 18 to soften and melt the coating in that part. 3, the upper half of the conductor 1 is exposed for a required length in the axial direction of the wire 2, and

By mutually approaching operation, both sides of the sheathing, which has been cut at both ends, are pinched and stripped from the conductor 1.
The entire periphery of the wire is exposed, and thus the intermediate peeling portion 20 is simultaneously molded at the peeling specified portion in the middle of the two groups of electric wires. In addition, after this intermediate peeling part 20 is intermediately divided at the cutting part 6, it is cut so that it becomes the contact part 8 of the exposed conductor of the required length.
A double length of the contact portion 8 is ensured. Note that the incision/peeling blade 13 forming the intermediate peeling portion 20 descends while holding the coating waste 26, and opens to remove the coating waste 26 by gravity and prepare for the next processing cycle.
