Problems solved by technology

[0008] However, in the configuration described in Japanese Unexamined Patent Publication No. 8-264134, the viscoelastic body is hardened due to aging, and its elastic performance deteriorates in a short time, making it difficult to absorb the vibration of the magnetic sheet well over a long period of time to achieve soundproofing.
In particular, the deflection yoke itself generates heat, so the heat aggravates the deterioration of the rubber

Embodiment Construction

[0025] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. figure 1 This is to show a state in which the television broadcast receiver 11 described in this embodiment is viewed from the front side. The television broadcast receiver 11 is mainly composed of a cabinet 12 and a support stand 13 for supporting the cabinet 12 .

[0026] Among them, a screen of a CRT (cathode ray tube) 14 is arranged at the front central portion of the cabinet 12 . In addition, a power switch 15, a receiving unit 16 for receiving operation information sent from a wireless remote controller, and the like are arranged in the housing 12 .

[0027] On the other hand, the above-mentioned support base 13 is connected to the central part of the bottom surface of the cabinet 12 in a rotatable manner, and supports the cabinet 12 in a state of being placed on the horizontal surface of a predetermined base 17 so as to stand.

Abstract

The invention provides a deflection coil device and a display device using the same. A spacer (25) for installing a horizontal deflection coil (28) and a vertical deflection coil (26), a hard support member (32) covering the surface of the magnetic body (31) and integrally fixed with the magnetic body (31), Formed in the predetermined position of the spacer (25), the concave fitting part (33) of a part of the supporting member (32) is matched with a wider contact area than when the magnetic body (31) is in contact, and the supporting member (32) The adhesive (34) that fixes the supporting member (32) to the spacer (25) in a state where a part of it is engaged with the mating portion (33).

Description

technical field [0001] The present invention relates to an improvement of a deflection device for cathode ray tubes such as those used in television receivers and color display devices. In addition, the present invention relates to a display device using the above-mentioned deflection yoke device. Background technique [0002] As is well known, the above-mentioned deflection coil device deflects the electron beams R (red), G (green), and B (blue) corresponding to the three primary colors emitted from the electron gun in the horizontal direction and the vertical direction, so that each electron beam The beams R, G, B are controlled to scan the fluorescent surface along a certain path. [0003] This deflection yoke device has a substantially trumpet-shaped spacer, and generates a magnetic field by passing sawtooth-shaped deflection currents synchronized with horizontal and vertical cycles respectively through horizontal deflection coils provided inside and vertical deflection...
