Description

[Detailed Description of the Invention] The present invention relates to an apparatus for manufacturing an electric wire with a branch fitting.

For vertical trunk flat cables installed in high-rise buildings, etc., Figure 2C and Figure 2D are installed in the factory.
As shown in (d-d sectional view of Figure 2C), the branch metal fittings B for connecting the branch branch lines are connected to the cable at predetermined intervals, and the cable is wound around a drum and transported to the site. After that, a branch line may be connected to the above-mentioned branching metal fitting.

To manufacture such electric wires with branch fittings, the wires are pulled out from the wire drum, the insulation layer is peeled off at predetermined locations on the wires to expose the conductors, and the wires are moved and the exposed conductors are compressed using a compressor. , and compressing the branch fitting onto the exposed conductor using this compressor may be repeated for each predetermined length of the wire to be drawn out.

However, if the length of the wire coating layer removed is short,
Even if there is a slight misalignment between the compressor and the exposed conductor when the wire is fed out, the die of the compressor may come into contact with the stripped end of the wire coating.
It is extremely difficult to adjust the amount of wire sent out for alignment. Such difficulty can be overcome by increasing the length from which the coating layer is removed from the wire, but this increases the length of the wire to be insulated later, making the treatment difficult.

The device for manufacturing electric wires with branching fittings according to the present invention was devised in view of the above points, and is made by compressing and connecting branching fittings at predetermined intervals of electric wires using a compressor. In an apparatus for manufacturing electric wire, the compressor is located between a wire sending machine and a wire winding machine, and a large number of rollers are arranged in a row so that the compressor can be moved back and forth along the direction of the electric wire. This configuration is characterized in that it is mounted on the rollers of the arranged pedestal.

The present invention will be explained below with reference to the drawings.

In FIG. 1, 1 is a wire sending drum, and 2 is a wire winding drum. W is an electric wire, and Fig. 2 A
As shown in FIG. 1, a flat electric wire can be used in which a plurality of stranded conductors a, . In FIG. 1, reference numeral 3 denotes a compressor located between the wire sending drum (wire sending machine) 1 and the wire winding drum (wire winding machine) 2. It is mounted on the rollers 5, . . . of the pedestal 4, which is formed by arranging the rollers 5, . Reference numeral 6 designates a workbench, and each time a predetermined length of the electric wire W is pulled out from the delivery drum 1, the coating layer of the wire is stripped on the workbench 6 to a length l shown in FIG. 2B. After each stripping, the exposed conductor portion A exposed by the stripping is moved to the position of the compressor 3 by pulling out the cable, and the compressed portion b of the branch fitting B is moved as shown in FIG. ₁ to the exposed conductor A. The distance g between this compression part b ₁ and the wire coating layer peeling end i ₁ is usually 10 mm, and the positioning of the compressor 3 and the compression part b ₁ is such that the die of the compressor 3 can peel off the wire coating layer. It is necessary to do this with an accuracy of less than 10 mm to avoid scratching the edge. Such positioning can be easily achieved by adjusting the movement of the compressor 3, without relying on adjusting the amount of cable drawn out from the delivery drum.

In Fig. 1, 7 indicates the compressor 3 and the winding drum 2.
This is a workbench provided between the workbench and the workbench, and on this workbench, the compression connection portions of the branching metal fittings can be insulated by taping or the like, except for the battledore portion (b ₂ in FIG. 2C).

Instead of stripping the wires on the workbench, it is also possible to wind the wires with the insulating layer stripped at predetermined intervals around a delivery drum and send them out.

The apparatus for manufacturing electric wires with branching fittings according to the present invention has the configuration as described above, in which a compressor for compressing and connecting branching fittings located between a wire sending machine and a wire winding machine is moved in the direction of the electric wire. Since the compressor is mounted on the rollers of a pedestal with a large number of rollers arranged in a row so as to be able to move back and forth along the wire, the compressor should be used to compress the branching metal fittings that are attached to the wires at predetermined intervals. Even when the compressor becomes larger and heavier, such as when compressing and connecting branching fittings to electric wires made of large-sized conductors, it can be easily and accurately aligned to the parts without requiring excessive labor. Can be aligned smoothly.

In addition, since the positioning accuracy of the compressor can be achieved with an accuracy of less than 10 mm, the length of stripping the wire coating layer when installing the branch fitting can be minimized, and the The insulation treatment of the compression connection part can also be simplified, and therefore, it becomes possible to manufacture the electric wire with the branch fitting at low cost.

Incidentally, finely adjusting the amount of wire drawn out using the sending drum or winding drum as described above,
Usually drum-wound wire (especially large size wire)
This was extremely difficult due to the drum winding. That is, according to the manufacturing apparatus of the present invention,
As long as the approximate amount of wire drawn out from the delivery drum or take-up drum is determined, fine adjustments can be made using the compressor, thereby simplifying the positioning work.
