Description

[Detailed description of the invention] The invention relates to a parallel insulated wire in which a plurality of core wires are arranged in parallel in the width direction and covered with an insulating resin.
In particular, the present invention relates to a parallel insulated wire that is easily cut by a certain length from the end so as to have a predetermined interval in the width direction to form a wire having a plurality of branch portions.

In the case of conventional parallel insulated wires, as shown in Fig. 1, core wires 1 are arranged at equal intervals l in the width direction and covered with insulating resin ribbons 2, and the core wires 1a and the insulating resin ribbons are arranged at both ends. The distance m to the end face of the ear part 2a of No. 2 is formed to be slightly smaller than the above-mentioned interval l, but for example, when connecting a cable connector to the end in the longitudinal direction, the following processing is performed. .

That is, generally, as shown in FIG. 2, the ears 2a at both ends of the insulating resin ribbon 2 are cut thinner than those shown in FIG. 1 so as to have an appropriate clearance with the inner wall surface of the housing of the cable connector.

However, this dimension m is generally about 0.6 mm,
If cutting errors are also taken into consideration, it can be seen that such cutting preparation work is extremely difficult and takes a lot of man-hours.

FIG. 3 is a plan view of the above-mentioned parallel insulated wires with the sheath removed by a certain length from both ends in the longitudinal direction and cable connectors 3, 3 attached, and FIG. , 3b are attached.

In order to form this branch part 4, a certain length is cut from the end along the longitudinal direction at the central flat part 2b of the parallel insulated wire shown in FIG. 2, unnecessary parts are removed, and the cable connector 3a, After processing the clearance with the inner wall surface of the housing 3b, the cable connectors 3, 3a, and 3b are attached.

Therefore, removing the unnecessary parts mentioned above, or
Machining to provide clearance is troublesome,
It is difficult to easily manufacture parallel insulated wires having branched portions, and it is also impossible to avoid wasting the material to be cut.

The present invention was developed based on the above-mentioned circumstances, and there is no need to further cut the ears when attaching a cable connector, and parallel insulated wires with connectors can be manufactured in large quantities economically and easily. It is an object of the present invention to provide a parallel insulated wire that allows manufacturing of a parallel insulated wire with a connector that has branch portions spaced apart from each other in the width direction.

Embodiments of the present invention will be described below with reference to the drawings.

5 to 7 are perspective views of parallel insulated wires according to the present invention, and the core wires 1 arranged in parallel in the width direction are covered with an insulating resin ribbon 2, which is different from the conventional structure. There is no difference.

However, in FIG. 5, the central flat portion 2b
and the distance m between the ears 2a at both ends are made equal in the manufacturing process, and the distance m is less than twice the clearance between the cable connector and the inner wall surface of the housing. Therefore, by cutting in the longitudinal direction at the center of the central flat portion 2b, the cable connector can be easily attached by simply exposing the core wires 1 at both ends in the longitudinal direction.

Therefore, it is no longer necessary to cut the ears to fit the dimensions of the cable connector to the housing as in the past, and by dividing at the central flat part 2b, a large number of parallel insulated wires with connectors of the same type can be produced. Moreover, it can be manufactured quickly.

Note that the parallel insulated wires described above can be easily manufactured by changing the groove width of a conventionally used forming roll having grooves at equal intervals.

In the case shown in Fig. 6, the core wire 1 is
The interval between the two is l, and in the B part, the interval n is different from the interval l, and the central flat part 2
In b, a certain length is cut in the longitudinal direction to facilitate the manufacture of a parallel insulated wire with a cable connector having a branch part as shown in FIG.

Furthermore, what is shown in Fig. 7 is part A, part B, and part C.
The spacing between the core wires 1 in each section is set at different intervals of l, n, and p, making it easier to manufacture a parallel insulated wire with a cable connector having three branch sections with different intervals.

The cable connectors shown in FIGS. 6 and 7 can be cut entirely at the central flat portion 2b or the narrow interval portion 2c, and cable connectors may be attached to each portion independently.

As is clear from the above description, according to the present invention, the widthwise spacing of the positions to be cut is made different from the spacing of other parallelly arranged core wires, and a narrow spacing portion is formed, which is convenient for attaching the cable connector. , it is possible to efficiently manufacture parallel insulated wires with cable connectors having branch portions in large quantities.

Furthermore, since there is no step of cutting the ears according to the clearance of the cable connector, the number of man-hours can be reduced and the waste of insulating resin can be avoided, which greatly contributes to the reduction of manufacturing costs.

In the embodiment of the present invention, the description has been given of a case in which the sheet has three sections spaced at different intervals in the width direction, but the number of sections is not limited to these.
