A typical type of cable used in various types of office equipment, telephones, audio equipment, etc. is formed by dry laminating a polyester film insulating support layer and a soft polyvinyl chloride film as an insulating sheath layer. A flat cable is formed by sandwiching and bonding several conductors between two sheets of covering material. Recently, as electronic circuits have become more complex and devices have become smaller, it has become necessary to increase the number of conductors in a single cable and reduce the distance between the conductors. When the above-mentioned cable is used in a part that is repeatedly bent or slid, the insulating sheath layer of the covering material and the conductor are not bonded, so there is a risk that the cable will peel off during use and shoot between the conductors. Another type of cable is one in which a conductor is sandwiched between two sheets of sheathing material formed by using a polyester film as an insulating support layer and coating this with a polyester resin containing a flame retardant as an insulating sheath layer. It is formed by In this type of cable, the insulating sheath layer of the sheathing material and the conductor are well bonded, so there is little risk of peeling off during use, but it is troublesome to process the end portion. The use of polyester resins with added flame retardants results in higher costs.

As shown in Figure 1, the flat cable of the present invention is made of polyvinyl chloride resin with an average degree of polymerization of 700 to 1,500, and a resin with a carboxyl group in the molecule of 1 to 50.
The conductor 2 is coated using a dry laminated laminate of a polyester film 3 and a film 1 of a composition consisting of parts by weight and an appropriate amount of a plasticizer of polyvinyl chloride resin. Although the illustrated examples are all flat cables using flat conductors, the present invention can also be applied to flat cables in which a large number of conductors with round cross sections are lined up and sandwiched between two films. In addition to the above, the composition also contains 1 to 1 as additives.
Stabilizers such as 5 PHR of Ba-Zn, Pb, and Ba-Cd, 10 to 50 PHR of DOP, plasticizers such as TOTM, polyester plasticizer, and wax, and appropriate amounts of various pigments may be used. If you want to increase cold resistance, it is recommended to add up to 30 PHR of ethylene-vinyl acetate copolymer, rubber, polyurethane, etc. To form a film from the above composition, known techniques such as calendering may be followed.

The cable of the present invention uses the above-mentioned laminated material as a covering material, so that the carboxyl group-containing resin in the composition mainly composed of polyvinyl chloride has an appropriate adhesive strength to the conductor. It acts as an adhesive and prevents plasticizer from bleeding. In this way, there is no separation between the covering material and the conductor, and the risk of the conductor being shot is eliminated. A layer of polyester film on the outside of the jacket gives the flat cable wear resistance and moderate stiffness.

A flat cable was obtained by sandwiching and pasting them together. For comparison, polyester 12μ/polyvinyl chloride
A coating material made of 80μ (dry laminate) and a coating material made of 12μ polyester/80μ polyester (extrusion coat) were prepared, and flat cables were obtained in the same manner as above. The adhesive strength between the cable sheathing material and the conductor and the lead-out processability of the cable end were examined for the examples and comparative examples, and the data shown below was obtained. Adhesive strength Unit of terminal part g/15mm width Extrusion processability Example 150 Good comparative example 1 0 Very good comparative example 2 1000 Effect of very bad idea The cable of this invention has a combination of sheathing material and conductor. Adhesive strength is at an appropriate level, and it will not peel off even when used on bending or sliding parts.Therefore, there will be no shortening caused by conductors touching each other, and it is easy to process the ends.
