Description

[Detailed Description of the Invention] This invention relates to a degaussing coil that can prevent so-called unraveling after forming a coverage line into a rectangular shape.

': Conventionally, when forming a degaussing coil, after winding a coated wire into a ring or square shape, in order to prevent it from unraveling, for example, as shown in Fig. 1a and Fig. 1S, There is.

That is, in the case of FIG. 1a, after the covered electric wire 1 is wound into a rectangular shape, a thread-like material 2 different from the covered electric wire 1 is wound and bundled.

In the case of FIG. 1, a tape-shaped material 3 different from the covered wire 1 is wound and bundled.

Therefore, the winding process for forming the coated wire 1 into a coil and the bundling process for forming the coated wire 1 into a ring or rectangular shape in order to prevent it from coming apart had to be carried out separately. .

There is also the disadvantage of using extra material in order to use another material 2 or 3 in this bundling step.

This idea was developed in consideration of the above points, and a degaussing coil that does not use extra material to bundle the insulated wires and uses a part of the insulated wires to easily prevent them from coming apart with a simple structure. The purpose is to provide

Hereinafter, embodiments of this front thread demagnetizing coil will be described based on the drawings.

FIGS. 2A to 2C are plan views showing the process order for explaining each embodiment.

First, as shown in FIG. 2a, the covered wire 11 is shaped like a square!
4. Wind the fill body 12 one turn less than the specified number of turns.
(wire bundle).

That is, the coil body 12 is formed by winding the covered electric wire 11 (N-1) times, where N is the specified number of turns.

Then, one final winding (hereinafter referred to as the final coated wire 11E) is slackened longer than the circumference of the coil body 12 to the extent that the following work can be carried out.

FIG. 2a shows the final coated wire 11E in a wound state.

As is clear from this Fig. 2a, the final covered wire 11
E is a rectangular coil body 12, ρ is two opposing sides, 1
2□", 'I2□".

After forming the final insulated wire 11E in this way, the final insulated wire 11E is divided into two places with equal circumference lengths and the square-shaped circumference is divided into two parts with equal lengths, and the fixing means 13a such as a tenip is put together. , 13 Stop at b.

In other words, regarding the parts of the fastening means 13a and 13b, in the center part of two opposing sides 123 and 124 of the rectangular coil body 12, the coil body 12 The electric wires 11E and the like are fastened by fastening means 13a and 13b.

Therefore, two opposing sides 12. ．． A slack is formed by the final covered wire 11E at the 12□ portion.

Next, the final coated wire 11E with this slack has occurred.
Grasp it with the center part at the top, as shown in Figure 2
Coil body] One opposite two sides 12□, 122 of 2
wind each.

Furthermore, as shown in FIG. 2C, the final covered wire 11 E
After winding up to the apex of the coil body 12, the two sides 12, . 12□ and fasten with fastening means 14a and 14b such as tape.

As a result, the coil body 12 and the final coated wire 11
E can be bundled together and prevented from coming apart.

As described above, according to the degaussing coil of this invention, a covered wire is wound in a square shape to form a wire bundle, and at least some of the wires are provided with slack on two opposing sides of the square shape. Since the wire bundle is wound around the two points that divide this slack into two equal parts, there is no need to perform the bundling process using other processes or other materials, and it is possible to bundle using a part of the covered wire. Therefore, not only material costs are reduced, but the manufacturing process is also simplified, making it easy and inexpensive.
