Abstract

PURPOSE:To form various kinds of deflection yokes by providing a notch by which plural ribs provided on the inner surface of a coil frame are divided into at least three parts, and by distributionally winding an insulating coating wire between each rib, or through the notch if required. CONSTITUTION:Plural ribs 3 are provided on the inner surface of a coil frame 8 in the winding direction of an insulating coating wire 2, and a notch 4 for dividing the ribs 3 into at least three parts, is provided. The notch 4 of a certain rib 3 will not be opposed to the notch 4 of an adjacent rib 3 thereto. By distributionally winding the insulating coating wire 2 between each rib 3 or through the notch 4 if required, a horizontal deflection coil 9 is formed. At the time of carrying out distributed winding, each rib 3 can be bridged by the insulating coating wire 2 through a certain notch 4, and the degree of freedom to the distributed winding can be increased, and various kinds of deflection yokes can thus be obtained by one kind of coil frame 8.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a deflection yoke having horizontal deflection coils distributed over a winding frame.

2. Description of the Related Art In recent years, there has been a demand for deflection yokes with distributed winding to improve the deflection performance of cathode ray tubes. Conventionally, this type of deflection yoke has generally had a configuration as shown in FIGS. 3 and 4. The configuration will be explained below. As shown in the figure, the winding frame 1 has a plurality of ribs 3 on its inner surface in the winding direction of the insulated wire 2, one notch 4 is provided in the rib 3, and the insulated wire 2 is inserted between the ribs 3. The horizontal deflection coil 5 was formed by applying distributed winding through the coil. Note that 6 is a vertical deflection coil, and 7 is a core.

However, in such a conventional deflection yoke, when performing distributed winding with the insulated wire 2, there are many restrictions by the ribs 3, the degree of freedom for distributed winding is small, and there are many types of deflection yokes. The problem was that it was difficult to create.

The present invention has been made to solve the above-mentioned problems, and aims to increase the degree of freedom for distributed winding, and to make it possible to configure many types of deflection yokes with one type of winding frame.

Means for Solving the Problems In order to achieve the above object, the present invention provides a plurality of ribs on the inner surface of the winding frame in the winding direction of the insulated wire, and also provides a notch that divides the ribs into three or more pieces. The problem is solved by winding the insulated wire in a distributed manner between the ribs and, if necessary, through the notch.

Effect of the present invention By using the above-mentioned problem solving means, the insulated wire can be passed between the ribs and wound in a distributed manner between adjacent ribs through arbitrary notches according to the coil specifications, and many types of deflection yokes can be constructed. .

EXAMPLE Hereinafter, an example of the present invention will be described with reference to FIGS. 1 and 2. Incidentally, those having the same configuration as the conventional example are given the same reference numerals and the explanation thereof will be omitted.

As shown in the figure, the winding frame 8 is provided with a plurality of ribs 3 on its inner surface in the direction in which the insulated wire 2 is wound, and a notch 4 that divides the ribs 3 into three or more pieces. Notch 4 of arbitrary rib 3
are arranged so that they do not face the notches 4 of adjacent ribs 3. Distributed winding is applied to the insulated wire 2 between the ribs 3 and, if necessary, through the notch 4 to form a horizontal coil 10.

As described above, according to the deflection coil of the embodiment of the present invention, a plurality of ribs 3 are provided on the inner surface of the winding frame 8 in the winding direction of the insulated wire 2, and a notch 4 is provided to divide the rib 3 into three or more pieces. Since the insulated wire 2 is wound in a distributed manner between the ribs 3 and through the notches 4 as necessary, when performing distributed winding, the insulated wire 2 can be passed through any notch 4 and straddle the ribs 3. The degree of freedom regarding winding can be increased, and one type of winding frame 8 can constitute many types of deflection yokes.

Effects of the Invention As is clear from the above embodiments, according to the present invention, a plurality of ribs are provided on the inner surface of the winding frame in the winding direction of the insulated wire, and a notch is provided to divide the rib into three or more pieces. Since the insulated wire is distributedly wound between the ribs and through the notch as necessary, the degree of freedom for distributed winding can be increased, and many types of deflection yokes can be constructed.
