After the specified processes which follow, the thin wires are put in a single body by the use of a fusion attachment tape.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a wire arrangement method for attaching a connector to the end of a communication cable, and more specifically, a method for separating the ends of a communication cable in which a plurality of thin wires are tied together and bundled. , and relates to a method of aligning these wires in a planar manner in accordance with connector standards. The present invention also relates to a wire arrangement tool used therein and a wiring tool used therein.

[Conventional technology]

Currently, office computers and personal computers are connected to various peripheral devices via communication cables that have connectors of various standards attached to their ends.

Incidentally, attachment of connectors of various standards to the ends of communication cables has been carried out by conventional processes.

First, as a first step, the end coating of the communication cable 80 is peeled off, and a plurality of cables (approximately 13 to 50 cables) are glued and bundled.
Solve and separate the thin line groups 81.81, .

Next, as a second step, as shown in FIG.
3a, 83b and a welding base 85 which is arranged between the pair of wire straightening blades 83a, 83b and has similar grooves 84, 84, . . . While arranging the multi-grooves 82.8 in the standard order, use the pressing rod 87 to
4 in order and arrange them in a planar shape.

Then, as a third step, as shown in FIG.
1, place the fusion tape 88 on...

Finally, as a fourth step, the wire straightening blade 83 and the fusion base 85
While holding the wire alignment group 81, move it to the fusion splicer 89,
The entire fusion tape 88 is fused! 189 and thin line group 81.8
I, . . . are pressed and integrated by fusion.

As mentioned above, the process was carried out in four steps.

[Problem to be solved by the invention]

However, in the above-mentioned conventional process, the second process of aligning and pressing the line requires a lot of attention and takes a lot of time compared to other processes. It can be said that the number of pieces that can be processed in a certain amount of time is determined by the time required for this process. That is, the thin wires 81 in the straightening order are selected from the solved thin wire groups 81, 81, .
Sequentially align it with the groove 82b of the wire straightening blade 83b from the end,
This is because the pushing rod 87 was used to carefully push the pieces into the multi-grooves 82 and 84.

Therefore, it has been a problem to find a way to shorten the time required for this process and increase the number of pieces processed per unit time.

By the way, there is an automatic machine that uses a computer for this wire straightening. However, this method is not a method of arranging the thin wires in order from the end, but a method of arbitrarily grabbing the thin wires and placing them in a predetermined position, so the main body 90 of the line group becomes twisted, which does not look good. Not only that, but it also caused trouble in attaching a connector (not shown). In addition, the processing capacity was not much different from that of human labor, and the difference in defective rate was not at all low, so the investment efficiency was not good.

[Object of the Invention] After careful consideration, the inventor of the present invention has found that the second step involves a series of manual operations for selecting and inserting thin wires.

SUMMARY OF THE INVENTION An object of the present invention is to provide a communication cable arranging method that separates the steps of sorting wiring and pushing into multiple grooves and improves the overall arranging performance.

In addition, the present invention also provides wire arrangement equipment and wiring equipment used in this method.

(2) a fourth step of pressing the thin wires together with the fusion tape to fuse and integrate them with a fusion splicer; This is an improved process.

First, a rod-shaped guide piece with a rectangular cross section is prepared, and each thin wire is sequentially arranged and held in a plane according to a prescribed order.

Next, the guide piece holding the group of thin wires is arranged parallel to a single guide blade formed in a convex step on the wiring base.

Finally, while pressing the entire group of thin wires with a rod-shaped pressing member,
The thin wires are slid along the grooves toward the ends of the wire group, and each thin wire is simultaneously pushed into the multiple grooves of the guide blade and the fusion base.

(e) a holding member that is attached to a 3N slider base and is movable up and down and fixed flush with the upper surface of the fusion base; a pressing slider configured to be slidable in the direction of the groove of the base; (") having an opening formed slightly larger than the upper surface shape of the fusion base, the opening being aligned with the fusion base; At the edge of the opening of the wire-straightening base, when the wire-straightening base is placed on the base, a guide blade in which a plurality of grooves are formed so as to be formed at positions corresponding to the sides of the fusion base and to be continuous with the plurality of grooves on the upper surface of the fusion base;

Further, a wiring device having the following configuration is used as a device for wiring the ends of the unraveled communication cable to the guide piece in a predetermined order.

That is, (a) a wiring base formed in a substantially plate shape, and (b)
(c) a wire straightening blade which is formed in a convex shape in a peak shape on the wiring base and has a large number of grooves densely carved in parallel in the transverse direction of the upper surface; a guide piece stopper that can be fixed at a position touching the side; (the guide piece stopper for the dl 3 & wiring blade) -
(e) One or more cable stoppers are arranged on the wiring base on the side opposite to the JF cable stopper, and each of the jf cable stoppers is arranged on the wiring base, and each It can hold the cable, rotate in a plane parallel to the wiring base, and is held in such a way that it can be fixed at a desired position.

[For production]

With the above configuration, there is no need to directly select and push the fine wires into the fusion base and repeat this process one by one.
Using a wiring tool, arrange the thin wires on the guide piece in the standard order. Then, the entire guide piece is placed along the guide blade of the wire alignment base, and then pushed into the guide blade and the multi-grooves of the fusion base at the same time using a press slider to complete the line alignment. After this, similar to the conventional process, a fusion tape is used and a press is used to fuse the thin wires to integrate them.

Next, the lever 1 is released from the engagement part 14, the slider base 3 is pushed down, and the wire alignment groups 81, 81, . . . are peeled off from the fusion base 7. The entire wire is taken out from the base 2, and the line alignment is completed. After this, the conventional connector attachment is performed.

Incidentally, since the procedure for attaching the connector from this point onwards is a conventional method, a description thereof will be omitted.

〔Effect of the invention〕

Since the present invention is configured as described above, it produces the effects described below.

(11) The wire arrangement method of the present invention separates the wiring and pushing into the fusion base in the second step, rather than a series of steps, so the operator only has to pay attention to the wiring, which has the advantage of improving work efficiency. .

(2) Conventionally, pushing thin wires into grooves was done one by one using a push rod, which caused fatigue and limited the number of wires that could be processed. , this can be resolved.

(3) Furthermore, in the past, in order to increase the number of processed
It was necessary to increase the number of people involved in the second process, but with this line arrangement method, the wiring and the closet can be separated and only the wiring can be done using a guide piece, so only the people involved in this process can be done. It would be a good idea to increase it. In addition, if the process of wiring only is moved to another location, for example, to a place where the labor is cheaper, the overall number of wires processed can be increased, and in addition to the above-mentioned technical effects, economic effects can also be achieved. You can also expect

(4) In the wire straightening device, it is possible to push a group of fine wires into the groove all at once using a pressure slider.
This has the advantage of faster processing speed. In addition, since an elastic member is disposed in the pressing member, the probability of damaging the thin wire group is reduced.

(5) Wiring equipment uses a single guide blade instead of a pair of wire straightening blades as in the past, so the position of the hand holding the fine wire can be set relatively freely, improving work efficiency. It also has an improving effect.

(6) Since a plurality of cable stoppers are provided, connectors of various standard shapes can be easily accommodated.

(6) According to the practice of the present inventor, when line alignment is performed using the line alignment method, line alignment device, and wiring device of the present invention,
Compared to the conventional method, the number of lines processed was improved by about 80% or more.
