The present invention can be applied to any type of cathode ray tube with a color selection cover, and suitable for radiation, and spring. The shielding cover is fixed by the tension of the frame, and the ray tube is fixed on the frame. The shield is formed by punching metal tin. [Prior art] The cathode ray tube includes a color selective shielding cover located at a specific distance from the glass panel of the tube, and red, green and blue phosphor powder are deposited on the panel. Under the three-electron beam effect, 'each-correspondence-fixed main color', the phosphor array can regenerate the image on the screen. This mask allows each fixed beam to illuminate only the phosphor of the corresponding color. ^ The dyke shield must be placed and fixed during the manufacture of the tube, named ::: at a specific location on the tube. The fixing function utilizes a rectangular gold! The frame is extremely strong, and the shield is traditionally welded to it. The negative shielding cover assembly is installed in the panel of the pipe by using a suspension device. 'Hanging ^ 乂 3 3〗 亍 Three metal parts connected to the frame, each part contains a phase: the terminal of the spring, and an opening. The metal handle into the panel, the spring must be strong enough to support the large beam f of the frame / shield combination, and the weight can reach several kilograms. Traditionally, two types of mousse are used, placed in the middle of the sides of the frame, or in the corners of the frame. Large honey-:: The suspension is preferably placed in the corner. This arrangement has the advantage of providing, <mechanical robustness, ensuring the initial adjustment of the mask / screen distance. 82512 1223304 No need to change during the manufacture of the tube, and to complete Tubes provide better assurance of resistance to rupture. The frame / shroud combination must be able to be removed and reinstalled accurately several times during each step of the tube manufacturing process, i.e. by compressing the suspension spring to release it from the metal handle incorporated in the glass of the panel, if not Action, you must adjust the distance from the frame to the screen each time you reinstall. The large frame contains four suspension springs arranged on each side or corner of the frame. The spring is connected to a frame with a difference of wood, and then the frame / shield cover assembly is assembled in the panel of the tube. The opening of each spring must be engaged with each metal handle of the skirt 4 of the panel incorporating the tube, and the opening of the spring must coincide with the handle. In order to solve the positioning problem caused by the allowable amount of the handle and the opening position of the spring, three materials with a nominal diameter of _ are usually used to be accurately arranged on the truncated handle, and a spring has an opening diameter The front of a large spring opens straight L. This frame is then assembled in the panel without mechanical stress, which is much wider: absorbs the valley differences. To prevent any mechanical clearance between the frame and the handle, a circular disk with a diameter equal to the opening diameter of two identical springs is inserted into the handle and then welded to the fourth spring. However, it has been found that this manufacturing process has changed too much in the positioning of the mask and the screen: this change is caused by the flat disk on the spring. When it is connected, it is not ideal < = relative foot movement between pieces means round The final position of the dish is not the nominal position. The entire area of the mask surface is no longer the optimal position for the initial adjustment ', which can lead to costly recovery of the frame / mask set. [Summary of the invention] The present Maoming's "hanging-frame / shielding shield combination system can match this combination with 82512 1223304 in the panel of a cathode ray tube, without the disadvantages of conventional techniques. To this end, the color cathode ray tube of the present invention includes a glass panel on which a phosphor powder curtain is deposited. A color selection mask is disposed near the curtain, and a frame is used to fix the mask. The frame is substantially rectangular. The frame / shield cover assembly is fixed in the thickness of the panel by cooperating with a substantially truncated shank in the panel when supporting the device, and i is less—the support device is integrated—a metal P-knife and a spring. The θ p opening 'mouth' is engaged with the opening by a metal handle, which is characterized in that the size of the opening parallel to the screen surface is larger than the size of the opening perpendicular to the screen. [Embodiment]-A color cathode ray tube ⑴ 'is illustrated in Figures 2 and 3, which includes a three-part glass-encapsulated panel 2-a screen 3 made of phosphorescent powder, a funnel-shaped rear portion 4 and substantially The cylindrical head 5 surrounds the electron gun 6 to generate three electron beams in the screen direction. A color-selective shield called a tube with an opening or an electron beam path between the limbs is enclosed in «3 and electron gun 6_. The cover is connected to a solid frame (H). The frame is fixed to the position of the tube panel by a suspension device containing 8 sets of middle handles, which is included in the glass part of the panel. The frame 'and the opening 13 cooperate with the handle, and the end of the handle is cut off: the shape 0, the shielding cover must be arranged at a very special distance from the screen, the tube of yA ^ can work correctly, which means that each beam should be illuminated Corresponds to the main color heart powder. In the main Z-axis direction of the tube, the measured distance is called the “q distance”. As shown in the illustration, the Q distance is adjusted for accurate positioning, using a frame, 82825 Γ 广 = 接 'and considering the metal handle 8 The distance from the screen is accurate ... the handle is in the plane by the glass manufacturer when the board is gas-made, and must be positioned in a plane parallel to the screen surface. Pi ^ 2 Day 1—Positioning of the position 'makes it possible that the material is in the same plane: It is widely used-it must have a diameter larger than that of other spring openings = elastic spring, in order to compensate for these changes. Before the elastic insert is = 2 it is placed on the metal handle beforehand, and after that, the spring / disc combination 烊 二 = will make the frame unselfish, so it can prevent any mechanical operation. However, it must be acknowledged that the Z-axis gimbal of the King of Kings has received significant changes in foot position due to two factors. The positioning of η on the disk may not be optimal. The disk may be an elliptical position on the metal handle.-The flat connector may change the strong medium production 7 and / or the Q distance during welding. "Axe-Z" position, thus partially modifying the invention stems from the fact that the manufacturer of the front broken glass panel is more able to control the positioning of at least one metal handle 8 than in the past, for example, the position in the direction of the Z axis. Technology and experience have shown that the frame / mask system can allow 025 planes to be handled. 'This valley difference can be controlled during the manufacturing of the metal handle. As a result, the shape of the suspension spring can be modified compared to conventional techniques. Figure 3 Explains one embodiment of the elastic spring 19 of the present invention, which uses a suspension at the corner of the front panel to support the #tooth frame / shield. The spring is usually composed of a metal plate and includes a first-end 20 in a folded manner to be connected to it. A flat plate of the connecting frame 10, a second end 22 is located in a direction parallel to the good main axis ζ, and-the connecting portion "is located between the two sides H22 contains an opening 26, at least-the spring is elongated and is located on the axis Parallel symmetry △ on the first axis length 25, and located along the symmetry △ 'parallel to the screen of the 82512 1223304 tube-with Mo, "Shi opening 26 in 2 parallel directions and openings perpendicular to ..." in fact Engages with frusto-surface and is located on metal handle The openings of other springs above 8 are only ^^ Therefore, the child frame can include three standard yellow hands 9, each with a substantially circular opening 13, and the fourth spring 19 has an elongated opening 26. Because of the metal handle On the same plane and under the valley difference allowed by the system, the shielding cover is located at a predetermined distance Q, provided that the frame is inserted into the panel to coincide with the yellowish opening and the metal handle of the panel; the purpose of this move is to make the The suspension system with the metal handle has one degree of freedom, so that the absorption tolerance m is necessary for the metal handle in this plane parallel to the labor curtain 3. This degree of freedom is formed by the long opening 26 in the direction perpendicular to the direction of the screen 3. Provided. Depending on manufacturing tolerances, it would be ideal to use one or more of the springs in Figure 3 to make the suspension of the frame / shield and other suspension springs with round apertures 13 at the ends. The branch incorporated into this I ammo κ 19 | Finding the final immovability is achieved by welding a disk with a diameter equal to the diameter of the other circular apertures 13 of the standard spring 9. The minimum metal content when using it for cathode ray control, metal handle 8, spring 9 , 19 and round dishes are all in the same type and size of tube However, depending on the type and size of the tube, different tolerances must be allowed, because glass component manufacturers cannot fall below a certain tolerance, and glass components are too expensive to produce. Therefore, to cover all tube types including Diagonal 36 to 82 coffee tubes, preferably the ratio of the maximum size 24 to the minimum size 25 of the opening 26 is between 15 and 25. The embodiment of Figures 4a and 4b is excellent in making the Q value when necessary The change is reduced when the spring of the present invention is used. It has been found that when the diameter D of the opening 30 of the disc 29 and the size 25 of the opening of the spring 19 are the same value, the spring 19 on the metal handle is equal to 82512 -10- 1223304. The position of the disc is relatively high, and the free position error before connecting to the disc is equal to: And because of the truncated shape of the metal handle, it moves in the z-direction when welding, so the fixed d = z e. Tan (0) Among them, Θ is the angle of the tip of the truncated end of the metal handle, and 0 is the angle. E is the thickness of the disc. The problem of soil resistance. The size of the yellow opening is 25. Small value; therefore, in the embodiment for implementing the present invention, the angle θ is η. , The thickness of the disk is 0.4mm-the opening 30 has a diameter of 5.61 gall
’彈簧19之開口 26厚度為0.635 mm， mm。此外，其他懸裝置包含彈箬9 於5.61 mm，以便在每一金屬柄上有一 在z軸方向直徑為551 其圓形開口直徑13等 相同參考位置。 經驗顯示，圓碟29之開口30之尺寸及在2方向之彈菩開口 尺寸之差異必須選擇為4與2〇1之間，因為如超過2(1時/，、彈簧 不能與圓碟接觸，如小於d時，遮蔽罩在2方向將有與螢幕 相對之太大之變動。The thickness of the opening 26 of the spring 19 is 0.635 mm, mm. In addition, other suspension devices include impeachment 9 to 5.61 mm, so that each metal shank has the same reference position with a diameter of 551 in the z-axis direction and a circular opening diameter of 13 and so on. Experience shows that the difference between the size of the opening 30 of the circular disc 29 and the size of the elastic opening in the two directions must be selected between 4 and 201, because if it exceeds 2 (1 hour /, the spring cannot contact the circular disc, If it is less than d, the mask will change greatly in two directions relative to the screen.
