Description

Deflection yoke assembly

The present invention relates to a deflection yoke (DY) assembly, and more particularly, to a deflection yoke assembly in which a connection part is provided to improve a connection structure of a deflection yoke, a lead wire and a connection terminal.

Generally, the principle of electron beam deflection scanned from an electron gun is applied to a cathode ray tube (CRT), and a horizontal and vertical deflection magnetic field must be applied to the neck of the cathode ray tube to scan the electron beam. . The coils for making this deflection magnetic field are called horizontal and vertical coils, and basically, they are combined at right angles to each other and constituted by both deflection coils and ferrite cores are called deflection yokes. The winding structure includes a saddle-saddle type, a semi-toroidal type and a toroidal-toroidal type.

Referring to the drawings, the cathode ray tube 10 includes a panel 11 having a fluorescent film 11a emitting three colors on its inner surface, and a funnel 12 sealed to an end of the panel 11. An electron gun 14 for scanning the electron beam 14a is installed in the neck portion 13 of the funnel 12, and red, green, and blue scanned from the electron gun 14 are provided on the outer circumferential surface of the funnel 12. A deflection yoke 15 is provided to deflect the electron beam 14a.

The shadow mask 16, which is spaced apart from the fluorescent film 11a by a predetermined interval and has a plurality of electron beam through-holes, is welded and fixed to the frame 17. In addition, a stud pin 18 for supporting the frame 13 is fixed to an inner surface of the panel 11, and an electron beam emitted from the electron gun 14 is fixed to a side of the frame 13. An inner shield 19 for shielding and controlling the track of 14a) is provided.

Referring to the drawings, the deflection yoke 20 is provided with a cone-shaped separator 21, a horizontal deflection coil 22 provided on an inner circumferential surface of the separator 21, and an outer circumferential surface of the separator 21. The ferrite core 23 and the vertical deflection coil 24 wound around the ferrite core 23 are provided.

In addition, a connection terminal 25 is installed at a predetermined lower portion of the separator 21 to connect a plurality of lead wires 26. Connection terminals 27 are provided at ends of the lead wires 26 so as to be connected to other parts of the vehicle body.

The deflection yoke 20 configured as described above has a deflection magnetic field for deflecting the electron beam scanned from the electron gun as a potential is selectively applied to the horizontal and vertical deflection coils 22 and 24.

The deflection yoke assembly for deflecting the electron beam of the cathode ray tube may be classified into various types according to the lead wire connected to other components and the mounting portion of the connection terminal. In other words, various separate management such as length, thickness, color, and shape of the connection terminal are required. In addition, the deflection yoke also has a large number of derivatives according to the electrode array order, it is difficult to manage each one by one. Therefore, storage of various parts is required in accordance with the demand of the consumer, and workability is deteriorated, such as production and supply of each single product.

An object of the present invention is to provide a deflection yoke assembly having an improved structure so that the connection of the deflection yoke, the lead wire and the connection terminal is simplified and can be standardized.
