Abstract

PURPOSE:To allow the erection and fitting of a vertical coil and mounting of a ferrite core by directly adhering a cable guide formed into L-shape to the ferrite core, and winding a cable by utilizing the cable guide. CONSTITUTION:A deflecting coil is formed of an upper guide 1, a lower guide 2, a ferrite core 3, and a cable 4, and a L-shaped cable guide 5 is mounted on the upper guide 1. The cable 4 is wound and hooked on the cable guide 5 to form a coil form. The upper guide 1 and the lower guide 2 are directly adhered to the ferrite core 3 by use of an adhesive. At this time, the position to the ferrite core 3 is determined by utilizing the positioning projections 6, 7 of the ferrite core 3. Thus, the mounting of the ferrite can be performed simultaneously with the coil erection.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a deflection coil attached to a cathode ray tube of a television receiver or the like.

BACKGROUND OF THE INVENTION In the case of a saddle-type deflection coil that is conventionally attached to a cathode ray tube, as shown in FIG. For this purpose, a winding frame divided into left and right parts is used, and after winding the electric wire on the divided winding frame, the respective winding frames are combined and fitted to form a coil integrated with a horizontal coil or a vertical coil. It was constructed by attaching a ferrite core divided into two parts to the outside of the vertical coil.

Problems to be Solved by the Invention In the case of the conventional deflection yoke constructed in this manner, after the vertical coil was assembled and fitted, it was necessary to further attach the two-part ferrite core thereon.

Further, the winding frame is originally an insulating support for forming the wire into a coil shape, but in the case of a vertical coil, the ferrite core also serves as a support for forming the wire into a coil shape. That is, in the case of a vertical coil, it had a double support (a winding frame and a ferrite core).

The present invention has been made in view of these problems, and provides a deflection coil configured to assemble and fit a vertical coil and a ferrite core.

Means for Solving the Problems In order to solve the above problems, the present invention is to attach a wire guide having a hooked hand directly to a ferrite core, and to directly wind a wire around the wire guide.

Effect: Due to the above configuration, the winding frame and the ferrite core are integrated,
A deflection coil can be constructed immediately after winding the wire. Further, the coil, which conventionally had an unnecessary double support body, is reduced to a single support body, and the weight of the deflection yoke can also be reduced.

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

FIG. 1 shows an external view of one side of the deflection coil of the present invention. Lower guide 2. Huerai 1-Nia 73.
It is composed of electric wires 4.

The features of each part and assembly method will be explained below.

FIG. 2 is a detailed view of the upper guide 1 in FIG. 1. On top of this guide 1 is a hook-like electric wire guide 5.
When winding a wire around this wire guide to form a saddle-shaped deflection coil, the wire is hooked onto the wire guide.
It serves to create the coil shape.

FIG. 3 is a detailed view of the lower guide 2 shown in FIG. 1, and its structure and role are the same as those of the upper guide 1, so a description thereof will be omitted.

FIG. 4 shows the upper guide 1. The figure shows the lower guide 2 being attached to the ferrite core 3.

As is clear from this figure, the upper guide 1 and the lower guide 2 are directly bonded to the ferrite core 3 using an adhesive or the like.

Further, in FIGS. 2 and 3, positioning with respect to the ferrite core is determined using the positioning projections 6 and 7 of the ferrite core.

The fitting diagram is shown in FIG.

Since the deflection coil of this embodiment has the above-described configuration, there is no need to separately manufacture a coil using separately prepared windings as in conventional deflection coils, and the upper guide,
By directly bonding and attaching the lower guide to the ferrite core, a deflection coil can be formed by winding the electric wire.

That is, in contrast to the conventional work of assembling the coil separately and then attaching the ferrite core, according to the present invention, the core can be attached at the same time as the coil is assembled, which reduces the working time of this process by half, and furthermore, the coil can be assembled. Assembling and attaching the ferrite core are completed in one step, which doubles the accuracy.

In addition, this method eliminates the main part of the winding frame conventionally used, reducing the weight of the coil (in an actual example, in the case of a general product 90" 20-inch color television receiver, 50"
(This is equivalent to 7% of the total weight of the deflection yoke).

Effects of the Invention As has been made clear from the above explanation, the deflection coil according to the present invention has an upper guide and a lower guide, compared to the conventional procedure of winding a wire around a vertical coil and then attaching a ferrite core. Since the vertical coil is directly wound around the ferrite core that has been removed, and the vertical coil is attached to the horizontal coil, there is no need for the procedure of attaching a vertical winding frame, and there is also the effect that the vertical winding frame itself, which was previously required, is no longer required. .
