Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] In the present invention, only one side of the parallel group of conductor ends is finally exposed, and the conductor is reinforced by a reinforcing insulator from the opposite side. The present invention relates to a tape-shaped electric wire end-treated.

[Conventional technology]

In recent years, as a tape-shaped electric wire for a card edge type connector, a tape-shaped electric wire that has been subjected to a terminal treatment has been proposed in order to make the attachment / detachment easy and a stable fit.

That is, as shown in FIG. 3, the tape-shaped electric wire subjected to the terminal treatment includes a metal conductor 11 having a rectangular cross section and an insulator 12.
At the end of the tape-shaped electric wire 1 covered with, the insulator 12 is peeled off to expose the end of the conductor 11 evenly, and the reinforcing insulator 3 is attached to one surface of the conductor end and one surface of the insulator 12 to form them. The tape-shaped electric wire thus constructed has a structure in which it is reinforced by straddling it, and the reinforced end portion of the tape-shaped electric wire can be directly inserted into and removed from the connector.

[Problems to be solved by the invention]

By the way, this type of tape-shaped wire reinforced insulator is firmly bonded to both the metal of the conductor and the plastic of the insulator of the tape-shaped wire body at the terminal part so as to withstand the insertion / removal force with the connector. Must have been

However, in order to economically achieve the above-mentioned strong adhesion, it is difficult to obtain an adhesive showing a strong adhesion force to both the conductor and the plastic,
Therefore, the conductor is peeled from the reinforced insulator and the conductor is deformed,
One of the drawbacks is that the wire is broken or the reinforcing insulator is peeled off from the insulator of the tape-shaped electric wire, so that the number of practically insertable / detachable parts is reduced, and a product that can be used practically cannot be obtained.

[Means for Solving the Problems]

The purpose of the present invention is to insert / remove a card edge type connector. In the terminal-treated tape-shaped electric wire, the reinforcing insulator of the terminal processing portion can be firmly integrated with both the conductor and the insulator, and the possibility of disconnection of the conductor during insertion / removal is eliminated, and thus improved. It aims to provide things economically.

That is, the tape-shaped electric wire with the terminal treatment of the present invention is such that the end of the tape-shaped electric wire formed by sticking the plastic tape on both sides of the parallel group of the metal conductors having the rectangular cross section forms the insulator Strip off to form exposed areas on both sides of the conductor end parallel group only, and apply adhesive tape with adhesive that has good adhesive properties to the metal conductor on one side of the plastic tape that is the same material as the tape-shaped wire insulator. Stick on one side of the conductor end parallel group,
In addition, the outer surface of the adhesive tape with the plastic tape and the outer surface of one side of the insulator of the tape-shaped electric wire are continuous on one plane, and the adhesive of the reinforcing tape has good adhesive properties with the insulator of the tape-shaped electric wire. It is characterized in that the reinforced insulating material coated with is straddled over the adhesive-attached tape and the insulating material of the tape-shaped electric wire and is attached to each of them.

〔Example〕

FIG. 1 shows a preferred embodiment of the terminal-shaped tape-shaped electric wire of the present invention, and FIG. 2 shows an exploded view of the tape-shaped electric wire of the same embodiment. These Fig. 1,
In FIG. 2, reference numeral 1 denotes a tape-shaped electric wire, the terminal portion of which is subjected to terminal treatment.

The tape-shaped electric wire 1 is formed by arranging parallel metal conductors 11 each having a rectangular cross-section in the form of a rectangular annealed copper wire in parallel to form a parallel group of metal conductors.
Is formed, and all the insulator is stripped off at its end to form a double-sided exposed portion of only the conductor end parallel group, and the adhesive-attached tape 2, from one side of the conductor end parallel group, And the reinforcing insulator 3 are sequentially attached.

Then, the adhesive-attached tape 2 is obtained by applying the adhesive 22 having good adhesive properties to the metal conductor 11 on one surface of the plastic tape 21 that is in the same material chamber as the insulator 12 of the tape-shaped electric wire 1. The adhesive tape is attached to one surface of the conductor end parallel group 11 with an adhesive 22, and the outer surface of the adhesive tape 2 with the plastic tape 21 and the outer surface of the insulator 12 of the tape-shaped electric wire 1 on one side are made uniform. It is arranged so as to be continuous on a plane.

The reinforcing insulator 3 is formed by applying an adhesive 32 having a good adhesive property to the insulator of the tape-shaped electric wire on one surface of the plastic tape 31.
And the tape-shaped electric wire insulator 12 and are attached to their outer surfaces.

The tape-shaped electric wire may be formed by extrusion coating a plastic material.

In order to confirm the effect of the present embodiment, 20 tin-plated rectangular soft copper wires having a thickness of 0.1 mm and a width of 1.27 mm are arranged in parallel at equal intervals, and polyethylene terephthalate having a thickness of 125 μm is coated with soft polyvinyl chloride. A tape-shaped electric wire constructed by pasting composite tapes laminated and integrated in advance from both sides of such a conductor parallel group is cut to a total length of 150 mm, and the insulating material at both ends of this cut product is peeled off from the tip to 5 mm, and exposed. Also, on the 5 mm portion, a tape was prepared by laminating a polyolefin adhesive to 85 μm thick polyethylene terephthalate, and further arranging the tape on the 15 mm portion from the tip of the back surface portion to a 140 μm thick polyerylene terephthalate polyester adhesive. Place the tape laminated with the adhesive, press it with a hot press at 200 ° C for 20 seconds and heat it to cure it. While it adhered and fixed to a solid to form a reinforcing layer.

As a result of actually measuring the number of insertions and removals of this tape-shaped electric wire with respect to the connector, it was able to endure 50 times of insertions and removals, and no defects such as peeling which hinder the insertion and removal occurred. It can be said that the effectiveness of the tape-shaped electric wire of the present embodiment is clearly shown even if the conventional tape-shaped electric wire cannot be inserted and removed because the conductor peels off and deforms at the 25th and 30th times.

[Effect of device]

According to the terminal-treated tape-shaped electric wire of the present invention as described above, it is possible to obtain a tape having a strong adhesive strength between the adhesive tape coated with the metal and the adhesive having good adhesive properties and the conductor end parallel group. Also, since the plastic tape of the adhesive tape is the same material as the tape-shaped electric wire, the reinforced insulator coated with an adhesive with good adhesive properties with the insulator of the tape-shaped electric wire It can be firmly adhered to both sides with the insulator, and by extension, the reinforcing insulator can be firmly adhered to both the conductor end parallel group of the tape-shaped wire and the insulator. Is greatly improved.

Adhesive tape was attached to one side of the parallel conductor group, and since the outer surface of the plastic tape and the outer surface of the tape-shaped electric wire were connected on a single plane, there was no difference in thickness at the base of the conductor,
Even when it is bent at the terminal portion, it is possible to eliminate the problem that the bending force is concentrated on a part of the exposed conductor portion to break the wire, and the bending resistance can be improved.

It is possible to provide a truly useful tape-shaped electric wire of this type, which is endowed with such effects and can withstand insertion and removal 50 times or more.
