DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tape electric wire formed by sandwiching a plurality of conductors, for example, a copper foil which is a flat conductor, between two insulating protective substrates. Tape that can be easily divided or branched
The present invention relates to a method for manufacturing a wire .

2. Description of the Related Art Japanese Patent Laid-Open No. 61-292818 discloses, for example, a core conductor b of a tape electric wire a as shown in FIG. , B, there is proposed a processing device for perforating a perforation d in an insulating protection base material c. However, it is very difficult to perform the perforation d parallel to the conductor b, and an expensive processing apparatus is required. Further, when the tearing operation of the tape electric wire a is performed along the perforation d, the tear may reach the conductor b with excessive force, and the conductor b may be exposed, and a problem remains in reliability.

Japanese Patent Application Laid-Open No. Hei 6-349355 discloses that, as shown in FIG. 7, a plurality of conductors b 'are sandwiched between two insulating base materials c' and c 'and are thermally insulated before being thermally fused. Substrate c '
At a predetermined interval, a stripping tape e such as an aluminum tape was stuck on the inner surface of the tape, a perforation d 'was inserted along the tape e into the insulating base material c', and wires f were inserted into both sides of the tape e. A flat cable a 'is disclosed. The flat cable a 'has the advantage that the tape b can be easily peeled off and the conductor b' is exposed, so that it can be easily connected to other electric wires or electric devices. Since there is no perforation parallel to b ', it is inconvenient to separate the conductor.

SUMMARY OF THE INVENTION The present invention has been made in consideration of the above problems, and has as its object to provide a method of manufacturing a highly reliable tape electric wire which can be easily separated, divided or branched between conductors. And

[0005]

To achieve the above object, a method of manufacturing a tape electric wire according to the present invention is described in claim 1.
As described above, when two insulating protective substrates are bonded by a pair of bonding rolls, a method of manufacturing a tape electric wire by supplying a plurality of conductors at predetermined intervals from a tangential direction of the pair of bonding rolls. A plurality of conductors and a thread are simultaneously supplied by using a guide roll provided with an annular groove for a thread between a plurality of annular recesses for the conductor. When juxtaposed pair of the filament laterally, as claimed in claim 2, using a guide roll in which the annular groove is 2 Jonami設between each annular recess.

According to the first aspect of the present invention, in the existing apparatus for manufacturing a tape electric wire, a plurality of conductors are formed by using a guide roll having an annular groove for a thread between a plurality of annular recesses for the conductor. What is necessary is just to supply a filament and a filament simultaneously, and a tape electric wire can be manufactured easily. Also, in the case of buried beside the pair of the filament to the tape cable, as claimed in claim 2, may be used the guide roll in which the annular groove is 2 Jonami設between each annular recess.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 1 denotes a tape electric wire, and a plurality of flat conductors 2 are arranged at a predetermined pitch, and both sides thereof are sandwiched between two insulating protection base materials 3 to thereby form a conductor housing convex portion. A concave joint 3b is formed between the base material 3a and the base material. The above is the same as the conventional tape wire. However, in the tape wire 1 of the present invention, each flat conductor 2,
A pair of filaments 4, 4 are buried between the two, that is, in the concave joint 3b for separating the conductor 2 in parallel with the conductor 2. FIG. 1 shows an example in which a pair of filaments 4, 4 are vertically arranged, but they may be horizontally arranged as shown in FIG.

The flat conductor 2 is generally a copper foil in a flexible printed wiring board or the like, and the insulating protective substrate 3 is generally a plastic film, sheet, tape or laminate of polyvinyl chloride, polyethylene, polyester or the like. Instead of the flat conductor 2, a core wire or a core wire that has been previously insulated and coated may be used, and paper or synthetic paper may be used as the insulating protection base material 3. Examples of the thread include natural fiber yarns such as cotton yarn and hemp yarn, synthetic fiber yarns such as polyester yarn, nylon yarn and acrylic yarn, inorganic fiber yarns such as glass fiber and carbon fiber, and copper wire, iron wire and aluminum wire. Thin metal wires can be used. It is preferable that the material and size of the filament 4 be changed according to the material and thickness of the insulating protection base material 3. For example, when the insulating protection substrate 3 is paper or synthetic paper, the thread 4 is preferably a natural fiber thread such as cotton thread or hemp thread.
In the case of a sheet, a thin metal wire is preferred.

As shown in FIGS. 3 and 4, the tape electric wire 1 is manufactured by a pair of bonding rolls 5 and 5.
A tape-shaped or sheet-shaped insulating protection base material 3 is supplied from both left and right sides, and a plurality of flat conductors 2 and thread-like materials are provided between the base materials by a guide roll 6 from a tangential direction of the bonding rolls 5. This is performed by feeding the body 4 and bonding the two substrates 3 and 3 by heat fusion or an adhesive.

The left and right insulating protection bases 3 and 3 are supplied in a state where a proper tension is applied by a tension roll (not shown). As shown in FIG. 4, the guide roll 6 has a plurality of annular concave portions 6 a in which the flat conductors 2 are accommodated, and an annular groove 6 b having a depth sufficient to accommodate the two filaments 4. The plurality of flat conductors 2 and the filaments 4 are bonded to each other by a guide roll 6 while maintaining a predetermined pitch.
5 is supplied. When two filaments 4 are arranged side by side as shown in FIG. 5, a guide roll having two annular grooves 6b between annular recesses 6a may be used.

It is preferable that windows 7 are provided at regular intervals in the left and right insulating protection bases 3 and 3, respectively. This window 7
By using the wire, it is possible to easily cut the tape wire 1 or connect the conductor 2 exposed from the window 7 to another wire or an electric device.

In the tape electric wire 1 of the present invention, since a pair of filaments 4 and 4 are embedded in the concave joint 3b between the conductors 2 and 2, as shown in FIG. By pulling them in the opposite directions so as to separate them from each other, the concave joint portions 3b are reliably and easily separated and separated from the embedded portions of the filaments 4 and 4. Accordingly, there is no possibility that the cut reaches the conductor b and is exposed as in the case of the perforation d shown in FIG. 6, and the reliability is improved.

As described above, according to the present invention, the tape
