The invention can be applied to any type of cathode ray tube with a color selection cover, and is suitable for a ray tube. The shielding cover is fixed by the tension of the frame, the ray tube is fixed on the frame, and the shielding cover in the ray tube is It is formed by punching a metal tin foil. [Another technology] The cathode ray tube includes a color selective shielding cover located at a specific distance from the glass panel of the tube. Red, green and blue phosphor powder are deposited on the panel. Under the three-electron beam effect, each corresponds to a fixed main color, and the phosphor array can reproduce the image on the screen. This mask allows each fixed beam to illuminate only the phosphor of the corresponding color. The color selection mask must be placed and fixed during the manufacture of the tube, and at a specific location on the tube during its operation. The fixing function is implemented with a rectangular metal frame, which is extremely strong and is traditionally welded to the shield. The frame / shield cover assembly is installed in the panel of the pipe by using a suspension device, the suspension device is a metal package welded to the frame, and each part includes a terminal constituting a spring, and an opening, which is incorporated in the opening The metal handle in the panel is engaged with the opening. The spring must be strong enough to support the weight T of the frame / shield combination, which can reach several kilograms in a large ray tube. Traditionally, two types of hearts are used. One is at the side of the frame, or at the corner of the frame. The suspension of large screen tubes is preferably placed in the corner. This arrangement has the advantage of providing an improved < mechanical robustness, which ensures the initial adjustment of the mask / screen distance. 82512 200411702 No need to change during manufacturing and completion The tube provides better guarantee of resistance to rupture. The frame \ mask assembly must be able to be disassembled and reinstalled accurately several times during each step of the manufacturing of the tube, that is, the metal handle in the broken glass of the panel is compressed by compressing the suspension spring to release the text. If you do this, you must adjust the distance from the frame to the screen every time you reinstall. Frame 0 contains four suspension springs arranged on each side or corner of the frame. The spring is attached to the frame with m, and then the frame / mask combination is assembled in the official panel. The opening of each spring must be engaged with each metal handle of the skirt of the panel incorporating the tube, and the opening of the spring must coincide with the handle. In order to solve the problem of positioning caused by the tolerance of the opening position of the spring, two hanging same springs with fixed diameter openings are used for the accurate placement on the top-shaped handle and a spring opening The diameter of the previous spring is larger than the diameter. The frame is then assembled in the panel without mechanical stress, and the larger opening absorbs the valley differences. In order to prevent any mechanical gap between the frame and the handle, a circular disk with a diameter equal to the opening diameter of the elastic lens is inserted into the handle, and then welded to the fourth but has been issued; see this manufacturing process that changes the positioning of the mask and the screen too The movement of the dagger is caused by the welding disc on the spring. When welding, the root is ignored: between pieces: the movement means that the final position of the disc is not the nominal position i. It is the best position for initial adjustment, which can lead to costly recycling of the frame / mask set. [Summary of the invention] The suspension-frame / shielding mask assembly of the present invention is purely capable of disposing the assembly 82512 200411702 in the panel of the cathode ray officer, without the disadvantages of the conventional technique. … For this reason, the two color cathode ray tubes of the present invention include a glass panel on which a phosphor powder screen is deposited ... A color selection mask is arranged close to the curtain ^ 'a frame to fix the mask, the frame is substantially rectangular, the frame The / shield cover combination is fixed in the panel by a k-cloth and fixed in cooperation with a substantially truncated handle. The support device is integrated in the thickness of the panel-a metal #knife that forms a spring and a metal handle containing an opening. That is to engage with the opening, its characteristics

J [Embodiment] Color cathode ray tube As shown in FIG. 2, it consists of a three-knife < glass-encapsulated panel 2 deposited in a panel 3 _ a screen made of light powder, a funnel-shaped rear portion 4 and a substantially cylindrical neck portion 5 surrounding the electron gun 6 to Three electron beams are generated in the direction of the curtain. " A color selection mask 11 is perforated with an opening or a gap 12 placed in the electron beam path. Only "Reward" is located between the screen 3 and the electron gun 6. The shielding cover 11 is attached to a solid < frame 1G, which is fixed in position in the panel of the tube by a suspension device of 8 sets of metal handles included in the glass skirt 7 of the panel, and is welded to the panel 9 with a spring 9 On the frame, and with the opening 13 to cooperate with the handle, the end of the handle is a cut-off item, and the mask must be arranged at a very special distance from the labor curtain, so that the ## can work correctly, which means that each beam should be illuminated correspondingly. The main color of the continuous light powder α is in the direction of the tube. The measured distance is called the "q distance." As shown in Figure 1, the Q distance is adjusted for accurate positioning. The welding of the opening 13 and the positioning of the handle. The handle is in the manufacturing of: the two genera, inside, and must be positioned on the glass A curtain surface of the two embedded panels parallel to the surface. The significance is that it must be used—and may be located in different planes, with open springs, in order to compensate for these changes ::, =: mouth straight: ... The dish is placed on a metal handle beforehand 入 # 入 &则;- Rounded up so that the frame does not move, which prevents the ^ yellow / disc combination from being welded in one place The direction of the main Z axis is determined by the mechanical operation. However, it must be acknowledged that the cover has received a large change for a factor. When the if is connected, the handle of the disc is an elliptical position, and the handle is not the most Jia's round disc may be changed when the gold-connector is soldered. * 7. Q distance is changed ... at the k position, so it is partially changed: the invention originated from the fact that the front broken glass panel Manufacturers are more able to control the positioning of at least one metal handle 8 than in the past, for example, the position in the Z-axis direction. Wu, Shi, and experience have shown that the frame / shield system can allow the Q value of G25 · Valley difference can control the position of the metal handle during the manufacturing of the panel. ―The shape of the fruit suspension elastic yellow can be modified compared to the conventional art. Figure 3 This is an example of "Elaskan Yellow 19", which uses the corners of the front panel. The suspension is supported by a support frame / shield. The spring is usually composed of a metal plate, which includes a first end 20 in a 1-fold manner to be welded to a flat plate connected to the frame 10, and a second end ^ parallel to the main axis z of the tube. In the direction, and-the connecting portion M is located between the two ends. The second end 22 includes an opening 26, to A spring is oblong on the first axis length 25 of symmetry △ parallel to the z-axis of the tube, and on the second axis of symmetry zv parallel to the screen of the tube 82512-9200411702. The opening m parallel direction and The openings that are perpendicular to the screen direction are actually the same as the openings of the other elastic lenses above the frusto-surface handle 8. Therefore, the frame may contain three = quasi-suspension springs 9, each having a substantially circular opening 13, with- Long opening 26. Because the metal handles are on the same plane, and two: Xu: the passenger is located at a predetermined distance Q, provided that the frame is inserted into the panel to coincide with the opening of the spring and the metal handle of the panel; The purpose is to make the suspension system including the spring and the metal handle have a degree of freedom to make the absorption tolerance necessary for the metal handle in this plane parallel to the screen 3. This degree of freedom is provided by the elongated opening% in the direction perpendicular to the direction of the screen 3. Depending on manufacturing tolerances, it would be ideal to use one or more of the springs of Figure 3 to make the suspension of the frame / shield and other suspension springs with circular apertures 13 at the ends. The final immovability incorporated into the support of the elastic yellow 19 of the present invention is achieved by welding a circular disk with a diameter equal to the diameter of the other circular apertures 13 of the standard spring 9. In order to minimize the metal parts used in the manufacture of cathode ray tubes, the metal handles 8, reeds 9, 19 and discs are the same in all types and sizes of tubes. 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 cannot be produced because they are too expensive. Therefore, in order to cover all types of pipes, including pipes from 36 to 82 mm diagonally, the ratio of the maximum size 24 to the minimum size 25 of the opening 26 is preferably between 1.5 and 2 5. The embodiment of Figs. 4a and 4b is excellent in changing the Q value when necessary, and lowering when using the spring of the present invention. It has been found that when the diameter of the opening 30 of the disc 29 is the same as the size 25 of the opening of the spring 19, the spring 19 rises on the metal handle relative to the position of the -10- 82512 200411702 disk, and because of the metal handle The truncated shape can be freely moved in the z direction on the welded soil disc, so the positioning error in the z direction can be equal to: d = ± e. Tan (0) where IΘ is the truncated end of the metal handle The angle of the tip, e is the thickness of the disc. In order to prevent this, the diameter D is a small value; therefore, in the embodiment for implementing the present invention, the sound level 0 is 12. The thickness of the disk is 0.4. The opening 30 has a diameter of 561 and the opening 26 of the elastic kappa 19 has a thickness of 0.635 mm and a diameter of 5 5 in the z-axis direction. In addition, the home device includes a spring 9 with a round mouth diameter of 5.61 mm, so that there is-the same reference position on each metal handle. Experience shows *, the size of the opening 30 of the round disc 29 and the difference in the size of the impulse opening rule of Z Fang Shao must be selected between 2d, because if it exceeds _, the elastic bullet does not touch the round disc, such as less than d Zi,; ^ "When 10,000, d, the mask in the Z direction will have a relatively large change relative to the screen. The embodiment does not constitute a limitation of the present invention, and the present invention can also be implemented in a frame / shield covering the center of the flashback.
