Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a winding drum for electric wire.

[Conventional technology]

Electric wires include bare wires and insulated wires whose surfaces are coated with insulating materials such as rubber and synthetic resin. Wiring wires and communication wires using these wires are wrapped in drums by wire manufacturers. It is shipped rolled.

This drum is made of metal and has disk-shaped side walls fixed to both sides of a cylindrical body so as to be concentric with the body.

Then, at the site where electric wires are to be installed or laid, the electric wires are directly pulled out from this drum.

[Problem that the invention attempts to solve]

As mentioned above, the electric wires are wound around the body between the side walls of the drum, but since the drum is made of metal, rust that occurs on the surface of the drum may damage the bare wires directly, and the insulated wires may become contaminated with the insulating material on the surface. In some cases, the parts were damaged or corroded by rust. Such electric wires were unsuitable for use in wiring or communications.

[Means for solving problems]

SUMMARY OF THE INVENTION In view of the above-mentioned problems of the conventional electric wire winding drum, it is an object of the present invention to provide a drum that protects electric wires from dirt and corrosion.

In order to achieve this objective, the present invention is characterized in that surfaces that come into contact with electric wires, such as the peripheral surface of the body of the drum and the inner surface of the side walls, are covered with a protective sheet.

〔Example〕

An embodiment of the present invention will be described in detail below with reference to the drawings.

Fig. 1 shows a winding drum according to the present invention, in which metal disk-shaped side walls 2 having a diameter larger than the body 1 are integrated on both sides of a metal cylindrical body 1 and coaxially with the body 1. This is the same as before.

The present invention is characterized in that a protective sheet 3 made of synthetic resin is attached to the outer circumferential surface of the trunk portion 1 and the inner surfaces of both side walls 2 to cover them.

This protective sheet 3 is coated with adhesive on one side,
This adhesive surface is covered with release paper, and when used, the release paper is peeled off and the adhesive surface is pasted on the body 1 and side wall 2. The protective sheet 3 is attached to the body 1 and side wall 2. It is removable.

The entire outer circumference of the body 1 is covered with a single protective sheet 3.
or divide the circumferential surface into multiple parts in the circumferential direction,
The entire surface may be covered with a plurality of protective sheets 3 cut to the size of each divided surface. Also, side wall 2
In this case, the protective sheet 3 is cut into a circle according to the outer diameter of the side wall 2 and covered with a sheet with a hole in the center having the same diameter as the outer diameter of the body 1. The inner surface is divided into a plurality of surfaces according to the size and covered with a plurality of sheets 3 cut to the size and shape of each divided surface.

For example, if the outer diameter of the side wall 2 is small, the second
As shown in the figure, it is sufficient to divide the inner surface of the side wall 2 into four parts and apply four protective sheets 3, or if the outer diameter of the side wall 2 is large, the inner surface can be divided into six parts or more as shown in Fig. 3. The protective sheet 3 cut to the size and shape of each divided surface may be applied.

After winding the wire to the required length on the drum, approximately 70
Although the protective sheet 3 is heated and dried at a temperature of 40° C. for 4 days, the protective sheet 3 is made of a material that can withstand this temperature and does not change in quality.

[Effect of idea]

According to the present invention described above, since the surfaces with which the electric wires come into contact, such as the circumferential surface of the body 1 of the drum and the inner surface of the side wall 2, are covered with the protective sheet 3, the electric wires are not stained or corroded by rust.

During the installation and installation of electric wires, the protective sheet 3 may be torn or peeled off, but since the protective sheet 3 can be peeled off from the surface to which it is attached, replace the protective sheet 3 with a new one after pulling out all the electric wires. You can replace it with

[Brief explanation of the drawing]

Figure 1 is a front view of the drum of the present invention, and Figures 2 and 3 show the state in which the protective sheet is attached.
It is a sectional view taken along the line AA in the figure. 1 is a body, 2 is a side wall, and 3 is a protective sheet.

Claims (1)

[Scope of utility model registration request] In a winding drum for electric wire, metal disc-shaped side walls 2 having a diameter larger than that of the body 1 are integrally fixed on both sides of a metal cylindrical body 1 at a position concentric with the body 1.
A winding drum for electric wires, characterized in that the outer peripheral surface and the inner surface of the side wall 2 are covered with a removable protective sheet 3 made of synthetic resin.
