Abstract

PURPOSE:To obtain a compact cathode-ray tube by providing a step on a cathode-ray tube surface with which a mask opening portion engages, making the cathode-ray tube surface flush with the mask surface and providing a means of preventing slippage between them. CONSTITUTION:A step is provided on the periphery of a cathode-ray tube 3 in such a manner that it engages with the opening portion of a mask surface 2 of a cabinet 1. Additionally, the surface of the cathode-ray tube 3 is made flush with the surface of the mask portion and an elevation is provided on the mask portion. As a result, slippage of the cathode-ray tube 3 is prevented, and a more compact cathode-ray tube is obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a cathode ray tube that can be used in television receivers and the like.

2. Description of the Related Art In recent years, television receivers have become larger and more compact, and competition among manufacturers has become more intense.

In addition, the cathode ray tubes and masks of television receivers from different manufacturers are becoming very similar, making it difficult to differentiate them.

An example of a conventional cathode ray tube will be described below with reference to the drawings.

FIG. 4 is a perspective view of a cabinet in which a conventional cathode ray tube is installed, FIG. 6 is a front sectional view, and FIG. 6 is a front view, a plan view, and a side view of the cathode ray tube.

In FIGS. 4 to 6, 1o is a cathode ray tube, 9 is a cabinet, and 11 is a part of the cabinet 9, which is an inclined surface of a mask section attached along the surface 12 of the cathode ray tube 1o. Reference numeral 13 denotes a rib for preventing the cathode ray tube 10 from shifting due to dropping or the like. 14 is a cathode ray tube mounting ear to be attached to the cabinet 9, and 16 is a fluorescent surface.

Problems to be Solved by the Invention However, in the conventional configuration described above, the cathode ray tube is displaced from the cabinet due to a fall, etc., so it is necessary to install rigs etc. on the top, bottom, left and right sides of the cathode ray tube to prevent displacement, which increases the external dimensions of the TV. It had

In view of the above-mentioned problems, the present invention provides a convex step on the cathode ray tube so that the mask surface of the cabinet and the surface of the cathode ray tube are the same, so that the mask opening of the cabinet at the step part of the cathode ray tube can be prevented from shifting due to dropping etc. Since the parts fit together, there is no need for ribs on the left, right, top, and bottom of the cathode ray tube, making it possible to provide a compact cathode ray tube.

Means for Solving the Problems In order to solve the above-mentioned problems, the cathode ray tube of the present invention is provided with a step that is convex from the outer periphery of the cathode ray tube so as to fit into the mask opening of the cabinet. The mask part is made flush with the surface of the mask part, and a rising part is provided in the mask part to prevent the cathode ray tube from shifting.

Effects According to the present invention, by making the surface of the cathode ray tube and the surface of the mask part flush with each other, the projection of the cathode ray tube and the opening of the mask are fitted, thereby preventing the cathode ray tube from shifting and making it compact. It is something.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view of a cabinet to which a cathode ray tube is attached in one embodiment of the present invention. In Figures 1 to 3,
1 is a cabinet, 3 is a cathode ray tube, and 2 is a mask surface that is part of the cabinet 1 and is provided flush with the surface 4 of the cathode ray tube 30. 6 is a step provided on the cathode ray tube 3, into which the rising portion 6 of the mask surface 2 is fitted.

7 is a cathode ray tube mounting ear, and 8 is a fluorescent surface.

Effects of the Invention As described above, according to the present invention, by providing a convex step on the cathode ray tube, the surface of the cathode ray tube and the cabinet mask surface can be made flush, and the rising portion of the mask opening can be formed at the convex step. will fit together to prevent it from slipping due to falling.

The conventional mask shape has no steps on the surface of the cathode ray tube, so the mask must be shaped like a forest.In order to prevent the cathode ray tube from shifting, ribs on the left, right, top, and bottom are required to prevent it from shifting, which requires a certain amount of space. was also necessary. The present invention can solve the above problems.
