Abstract

PURPOSE:To prevent the withstand voltage property of a cathode ray tube from being deteriorated and the generating voltage of stray emission from being lowered by forming from a material harder than that of a spacer at least those faces of electrode parts which are forced to abut against the spacer. CONSTITUTION:A thin film 11 of hard material stuck to those faces of electrode parts 8, 9 which are forced to abut against a spacer 10 is e.g. a titanium thin film stuck thereto by vacuum deposition. The titanium thin film 11 is harder than a stainless steel plate that forms the spacer 10, and so its surface will not have a flaw even if the spacer 10 is pulled out after beading. The withstand voltage of a cathode ray tube using this electron gun and the generating voltage of stray emission are thereby enhanced.

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to an electrode component constituting an electron gun of a cathode ray tube. [Prior Art] Figure 4 is a side view showing an electron gun assembled with conventional electrode parts before beading. In the figure (1)
.. (2), (3). (4) are Gl, G2G3, and G4 electrode parts each made of stainless steel thin plate; (5) . (ill). (7) is for Gl-G2 and G2- which are made of stainless steel plate, respectively.
Spacer for G3, G3-G4, (20), (30)
is a beading device that is inserted from above and below. To assemble the electron gun, attach electrode parts (1) to (0) to each electrode spacer (5).
) to (7) and place the beading jig (20).
(30) and position it. After beading this with heated beading glass (not shown), each spacer (5), (8). By removing the electrode parts (7), the electrode parts (1) to (0) are assembled at predetermined intervals. [Problem to be Solved by the Invention] Conventional electrode parts are constructed as described above, When the electrode parts are pulled out, the friction between the electrode parts and the spacer causes scratches on the surface of the electrode parts, which causes problems such as deterioration of withstand voltage characteristics and reduction of stray emission voltage when assembled into a cathode ray tube.This invention This invention was made to solve the above-mentioned problems, and aims to obtain an electrode part whose surface is free from scratches. [Means for solving the problem] This invention The electrode component according to the present invention is characterized in that at least the surface that comes into contact with the spacer is made of a harder material than the spacer. Even if the spacer is removed after being assembled into a gun, no scratches will occur. [Embodiments of the Invention] An embodiment of the invention will be described below with reference to the drawings. Figure 1 shows an example of an electron gun according to an embodiment of the invention when assembled. (11) is a cross-sectional view showing the state of electrode parts (8) and (9).
A thin film of hard material deposited on the surface that comes into contact with the spacer (10), for example a titanium thin film deposited by vacuum evaporation. This titanium F[(11) is harder than the stainless steel plate forming the spacer (10), so even if the spacer (IO) is removed after beading, no scratches will occur on its surface. FIG. 2 is a sectional view of another embodiment of the invention. This example is an electrode part (8). A titanium plating layer (l1) is formed on the entire surface of (9), and the same effect as the embodiment shown in FIG. 1 can be obtained. FIG. 3 is a sectional view of another embodiment of the invention. In this example, electrode parts (8)
.. (9) is implemented using a titanium thin plate, and the same effects as the embodiments shown in Figures 1 and 2 can be obtained. In the above example, titanium was used as a material harder than the spacer, but poron, zirconia, silicon titanium, silicon carbide, conductive ceramics, etc. may be plated or
It may also be applied to the surface of the electrode parts by ion plating or vapor deposition. [Effects of the Invention] As described above, according to the present invention, since at least the surface of the electrode component that contacts the spacer is formed of a material harder than the spacer, it is possible to obtain a cathode ray tube electron gun without scratches on the electrode surface. can. Therefore, this electron gun has the effect of significantly improving the withstand voltage and stray emission generation voltage of a cathode ray tube.
