In FIG. 5, 1 is a cathode ray tube, 2 is a cabinet for holding the cathode ray tube therein, 3 is a cathode ray tube mounting bracket, and 4 is a cabinet bracket. Here, the cathode ray tube 1 is fixed to the inside of the cabinet 2 by using screws on the cathode ray tube attachment fittings 3 protruding from the four corners and the cabinet fittings 4 provided at the four corners of the cabinet 2. FIG. 6 is a rear view of a conventional degaussing coil mounting device. 1 is a cathode ray tube, 2
Is a cabinet for holding the cathode ray tube therein, 3 is a cathode ray tube mounting bracket, 5 is a degaussing coil gripping component, and 6 is a degaussing coil. Here, one end of the degaussing coil grip component 5 is fitted to the cathode ray tube fitting 3, and holds the degaussing coil 6. FIG. 7 is an enlarged view of a conventional degaussing coil grip component.
In FIG. 7, 3 is a cathode ray tube mounting bracket, 5 is a degaussing coil gripping component, 6 is a degaussing coil, and 7 is a hook having elasticity at the center disposed on the degaussing coil gripping component 5 for holding the degaussing coil. is there. The degaussing coil gripping component 5 is mounted on the cathode ray tube mounting bracket 3. Here, the degaussing coil 6 is held so as to be sandwiched by the elastic hook 7 at the center of the degaussing coil grip component 3.

The degaussing coil is degaussed against the influence of the earth's magnetism on the cathode ray tube of a television receiver, a monitor television or the like, or the magnetic field from the outside.

[0005]

However, in the above-mentioned conventional structure, since the degaussing coil holding component having the elastic hook is mounted on the cathode ray mounting metal fitting, and the degaussing coil is mounted on the hook, the degaussing coil is fixed. There is no certainty, and because a degaussing coil made by winding an insulator around a copper wire coil is used, the degaussing coil hardens and comes off in cold regions, and to prevent this, increase the rigidity of the hook and fix it.

Further, there is a problem in that the cabinet and the cathode ray tube are complicated to disassemble for market service or recycling of a television receiver or the like provided with the degaussing coil mounting device.

The present invention solves the above-mentioned conventional problems, and an object of the present invention is to provide a degaussing coil mounting device in which the degaussing coil can be mounted easily and securely.

[0008]

To achieve this object, a degaussing coil mounting device according to the present invention has a degaussing coil having one end fixed to a side surface of a cathode ray tube and the other end having a curved portion protruding to the outside of the cathode ray tube. The degaussing coil is provided with a gripping component, and the outer edge of the curved portion of the degaussing coil gripping component contacts the cabinet member to hold the degaussing coil in the curved portion.

Further, the degaussing coil gripping component having a curved portion fixed to the side surface of the cathode ray tube and having an inside facing the cabinet member is provided, and the tip end of the bending portion of the degaussing coil gripping component and the cabinet member abut each other. It has a structure for holding the degaussing coil.

[0010]

With this structure, the demagnetizing coil is held in the curved portion by the outer edge of the curved portion of the degaussing coil gripping component projecting to the outside of the cathode ray tube contacting the cabinet member, or the protruding end of the curved portion contacting the cabinet member. Will be more certain to do.
