Abstract

PURPOSE:To improve workability by a method wherein the title guide plate is used as a guide which is fixed to a member for winding a wire, and at the same time, makes it possible to hook and fix the end of the wire. CONSTITUTION:A coil guide plate 4 is made by using nonmetallic material, e.g., resin having a specified thickness and rigidity. Said coil guide plate 4 is bonded and fixed on the wire winding surface of magnetic substance with a double adhesive tape 7 stuck on the central part of the plate. The coil guide plate 4 is bonded to a part of a square pole type magnetic substance 12 by using the double adhesive tape 7; a wire 11 is wound around a wire winding part 5, and hooking a wire part for winding start and winding end. Thus hooking is enabled only by the coil guide plate, and other members are not necessitated, so that parts cost can be reduced, and workability is improved.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a part for mooring the ends of an electronic component made by winding a wire.

[Summary of the invention]

The coil guide plate of the present invention is attached to a member on which a wire is to be wound for the purpose of improving workability, and is formed so that it can serve as a guide for winding the wire and at the same time moor and fix the end of the wire. It is characterized by having been.

[Conventional technology]

FIG. 6 shows a conventional example in which a wire is wound around a toroidal magnetic body. In the figure, a wire 2 is moored to a magnetic material 1 with an adhesive tape 3 at the beginning of winding, and after being wound several times, it is moored again with an adhesive tape 3, and after being wound several more times, the end of the winding is moored with an adhesive tape 3. It is moored to body 1.

Adhesive resin may be used instead of the adhesive tape 3.

[Problem to be solved by the invention]

Conventional mooring means as shown in Fig. 6, whether using adhesive tape or adhesive resin, have poor workability.In addition, when the wire diameter is large, the wound wire tends to loosen, In many cases, the beginning and end of the wire cannot be properly moored.

The present invention has been made in response to these problems, and an object of the present invention is to provide a coil guide plate that is operable and allows good mooring of winding ends even when the wire diameter is large. do.

Means for Solving Problem C72] In order to achieve the above object, the present invention uses a coil guide plate having two functions.

The first function is to fix the coil guide plate itself to the magnetic material.

The second function is to anchor the beginning and end of winding of the wire.

〔Example〕

Embodiments of the present invention will be described below based on the drawings.

(1) Description of the first embodiment FIG. 1(a) shows a plan view of the first embodiment, and FIG. 1(b) shows a side view of the first embodiment. The coil guide plate 4 is made of a rigid non-metallic material (e.g. resin) with a predetermined thickness, and the coil guide plate 4 is made of a rigid non-metallic material (for example, resin) with a predetermined thickness. The coil guide plate 4 is fixed with adhesive.

FIG. 3 is a plan view showing the installed state. Reference numeral 12 denotes a part of a magnetic body in the shape of a quadrangular prism, and the coil guide plate 4 of this embodiment is adhered with double-sided adhesive tape 7. The wire rod 11 (including the wire rod) is wound around the wire rod 5, and the beginning and end of the winding are entwined and moored in the wire rod mooring portion.

(2) Description of the second embodiment FIG. 2(a) shows a plan view of the second embodiment, and FIG. 2(b) shows a side view of the second embodiment.

To explain only the differences between this embodiment and the first embodiment,
Locking claw 1 instead of double-sided adhesive tape for attachment to magnetic material
0 is provided at the end 9 of one leg that does not have a wire anchoring portion. This locking pawl 10 makes attachment to the magnetic material even easier.

(3) Description of the third embodiment FIG. 4(a) shows a plan view of the third embodiment, and FIG. 4(b) shows a side view of the third embodiment.

This embodiment is basically a series of left-right symmetrical coil guide plates 8 of the second embodiment, and a locking pawl 15 for a magnetic body is provided at the center of the connecting portion 14.

Therefore, in the coil guide plate 13 of this embodiment, a total of six locking pawls, including four locking pawls 10, are provided at the tip end portion 9 of the leg.

FIG. 5 shows the state in which this coil guide plate 13 is attached to a magnetic body. FIG. 5(a) is a plan view, and FIG. 5(b) is a side view. The coil guide 13 of this embodiment is used to wind the wire 17 around the toroidal magnetic body 16. The toroidal magnetic body 16 has a rectangular cross-sectional shape, and the coil guide plate 13 is attached in advance with a locking claw along its outer circumferential surface, and a wire rod 17 with a wire diameter of about 1.7 mm (including the thickness of the coating) is attached to the coil guide plate 13 in advance. The wire is wound in two parts in the wire winding part 5,
The starting and ending portions of the winding are moored to the wire mooring section.

〔Effect of the invention〕

As explained above, according to the coil guide plate of the present invention, even a wire with a large diameter can be wound without loosening, and the position will not shift. Moreover, the wire rod can be easily moored at the beginning and end. Furthermore, since the winding position of the wire rod is determined by the mounting position of the coil guide plate, its positioning is easy.

In addition, since the coil guide plate of the present invention does not require any other parts for mooring the wire at the beginning and end of winding, parts costs can be reduced and workability is also good.
