部のみコンパウンドにて固定するものである。Conventional configuration and its problems In order to send deflection current to the horizontal and vertical coils in the flat yoke, vinyl-coated lead wires are used to connect the ends of these coils to the board. . The structure for attaching and fixing the lead wires of the conventional deflection yoke as described above will be described below with reference to the drawings. In FIG. 1, 1 is a lead wire, 2 is a fixed frame, 3 is a horizontal coil, a vertical coil, 4 is an exterior shield on the coil, 5 is a tightening band, and 6 is an alignment magnet. As shown in FIGS. 2 and 3, one end of the lead wire 1 is passed through the square hole 7 provided in the fixed frame 2, bent, and both ends of the horizontal coil and vertical coil 3 are connected to this by soldering. Only the connection part is fixed with compound.

う欠点を有していた。Therefore, when fixing the lead wire 1 as described above, the connection part, that is, the non-insulated part, may be exposed or even come loose from the deflection yoke body due to melting of the compound due to high temperature, chipping, cracking, or peeling of the compound due to mechanical impact. It had the following drawback.
発明の目的

端部とリード線との接続部をボビン内部に収納し、接続
部の安全性を高めた偏向ヨークを提供することを目的と
したものである。Purpose of the Invention In view of the above drawbacks, an object of the present invention is to provide a deflection yoke in which the connection parts between both ends of the horizontal coil and vertical coil and the lead wire are housed inside the bobbin, thereby increasing the safety of the connection parts. This is what I did.

体からの遊離が防止できるとともに、接続部に機械的衝
撃が加わることも防止できる。Structure of the Invention In order to achieve this object, the deflection yoke of the present invention is fitted with a cylindrical cover part provided at the rear of the bobbin along the outer diameter of the bobbin and having a part cut out in order to draw in the lead wire. This means that the entire storage area is made up of a lid plate. With this configuration, the connections between the horizontal and vertical coil ends and the lead wires are housed within the insulating resin cover and lid plate, preventing the connections from being exposed or coming loose from the deflection yoke body. It is possible to prevent mechanical shock from being applied to the connection portion.

り位置決めされる。DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. - FIG. 4 shows the fixing structure of the connecting portion between both ends of the horizontal coil and vertical coil of the deflection yoke and the lead wire in an embodiment of the present invention. In Fig. 4, the bobbin is a cylindrical bobbin fully wound with 8&i horizontal coils and vertical coils, and the rear part of the bobbin 8 has a partially cutout part 9 with a larger diameter than the bobbin 8.
A cylindrical cover portion 10 having a diameter is provided. There is a ring-shaped cover plate 12 that is fitted with the cylindrical cover part 1o that is integrated with the bobbin 8 to form the entire storage space, and has a projection piece 11 on a part of its outer periphery. It is inserted and attached to the bobbin 8 by being sandwiched between the flexible protrusion 13 provided on the bobbin 8 and the end surface of the cover part 10 . Note that the protruding piece 11 is positioned by the notch 10& of the cover portion 1o.
