Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a tape electric wire and a method for manufacturing the same.

A tape is a wire consisting of multiple foil-shaped or approximately circular cross-section conductors arranged parallel to each other and sandwiched from both sides by a tape made of flexible insulating resin, such as polyester, polyethylene, or nylon. These wires are covered, and have the following characteristics: they are lighter and occupy less space than electric wires in the United States, and they are connectable and have a high degree of freedom in wiring. Widely used for equipment wiring.

Conventionally, in this type of wire, the insulating coatings of each conductor have been made to differ in thickness for the purpose of easily distinguishing between each conductor for convenience of wiring and connection. In other words, as shown in FIG.
insulation coating 102A.

1U2B, 1lJ2c, are made to have different packaging to make it easier to identify each conductor, and each conductor is held under pressure by a pair of protective tapes 8.8 that are adhered to each other from both row sides. It is what it is. As an example of the protective tape 8, a laminate tape shown in FIG. 2 can be used. FIG. 2 is a cross section illustrating this laminated tape, and the first layer 81 of this laminated tape is made of a heat-sealable material such as polyethylene resin, and the first layer 81 is made of a material having excellent heat resistance and mechanical strength, such as polynis glue (81). It is made up of 8 layers of the 21st ring 82 using moon do, and the 81st wheel 8B made of polyvinyl chloride resin, for example, which has excellent flexibility.

In such a conventional Chigumi 11J2A102B, each conductor has a different color.

・Because it is formed by extrusion, there is not only a large amount of time wasted and material waste when changing the color of the extruder, but also a disadvantage that it requires considerable cost and effort to manage the resin raw materials of various colors. there were.

This invention was made to eliminate the drawbacks of the prior art, and the gist of this invention is to identify the four bodies not by their insulating coatings, but by identification tapes attached to them. be.

Referring to FIG. 8, a tape which is an embodiment of the present invention! Explain the lines.

A plurality of cane wires W each having an insulating coating 2 extruded around a conductor 1 are arranged parallel to each other on the same plane. On the surface of each of these strands, an identification coupe 4A is provided along the longitudinal direction.

4B, is added vertically. Next, each of the strands Ill
.

are each held in place by adhering together a pair of protective tapes B as shown in FIG.

The protective tape 8 is preferably transparent or semi-transparent so that the internal identification tapes 4A, 4B, . Since this identification tape is exposed when the tape is removed, it does not necessarily have to be transparent or translucent as described above. Further, as the protective tape 8, a laminated tape may be used as described above in the case of the prior art, but in the present invention, the characteristic is not in this laminated tape, so the protective tape 8 is used.
There is no need to limit it to the above-mentioned laminated tape.

FIG. 4 shows another embodiment of the present invention, in which identification tapes 4.A, 4B, etc. are placed around the strands.
The only difference from the previous embodiment is that each sheet is attached vertically. Identification tape is a tape that has distinctiveness in terms of color, markings, etc.

Now, with reference to FIG. 5, an example of the method for manufacturing the deep electric wire of the present invention will be explained. Cable wires W, W having insulation coatings 2 extruded by a conductor IK extruder 10.

-C is fed parallel to each other on the plane of 0 and -C. Of course, the cable wire may be supplied from the cable already stored in the winding bobbin 11.

Next, identification tapes, for example identification tapes 4 of different colors from each other.
A, 4B, and 4C are the delivery bobbins 8A and 8B, respectively.
, 8C, corresponding to element i and are vertically attached to each tree line.

Reference numerals 5 and 6 indicate the upper and lower (It!l) delivery bobbins of the anti-tilt tape 8, respectively, and a pair of protective tapes 8.
8 is fed from above the identification tapes 4A, 4E, -, etc. on the upper side, and 5 - is fed from the lower side of the plane where each conductor is lined up so as to be in surface contact with the 4 pieces on the lower side, and the whole is l It is sent between a pair of pressure rolls 7A and 7B.

Hot air is sent to the protective tapes 8, 8 from the hot air outlet 9 and heated, and the surfaces become molten, so the pressure roll 7A
As a result of being pressed between ,,7B, the upper and lower protective tapes 8
, 8 are bathed against each other, and in this way the torn identification tape hands A, 4B, etc. and the cable wire W are fixed in the initial arrangement position, completing the Chigumi spinning.

Although it is generally not necessary to weld between the identification tapes 4A, 4B, etc. and the protective coupe 8, the length of the opening becomes longer due to connection work, and the identification tape may fall off at that part. In special cases where identification becomes difficult, use identification coupe 4A.
, 4B, · and the protective tape 8 would be better.

In the tape electrofusion and its manufacturing method according to the present invention, it is possible to form an insulating coating of the same color on each conductor inside, thereby eliminating time loss and material waste when changing colors during extrusion work. At the same time, management problems with the resin base F are eliminated, and manufacturing costs are reduced. Since there is an identification tape with the conductor in close proximity to the conductor, it is easy to identify the conductors, and there are advantages such as making connections and other work in dusty areas unnecessary.
