Abstract
The present invention relates to a positioning structure for assembling the eccentric pole pieces of an electron gun of a cathode ray tube, which mainly assembles the pole pieces of the electron gun in the cathode ray tube by a three-shaft positioning mode of an assembling clamp. When the through holes of both sides of each pole piece causing electron beams to pass have eccentric hole diameter, positioning elements corresponding to the eccentric hole diameter of the eccentric pole pieces are arranged on the two outer side positioning shafts of the assembling clamp. Therefore, when the eccentric pole pieces of the electron gun are penetrated and sheathed on the three positioning shafts of the assembling clamp, the positioning elements can be clamped in a gap generated between the eccentric hole diameter of the eccentric pole pieces and the positioning shafts, and the eccentric pole pieces can be precisely positioned on fixed positions.
Description
The present invention is about a kind of assembling and positioning structure of eccentric polarizing sheet of electron gun of cathode ray tube, especially refer to a kind of via setting element, make cathode ray tube when the eccentric polarizing sheet of assembling electron gun, eccentric polarizing sheet is positioned on the fixed position exactly, thereby makes the three-beam electron-beam of electron gun accurately be incident upon location structure on the video picture screen.
The application of cathode ray tube is very general at present, such as traditional color TV and even high-resolution computer monitor, even medically other application of ultrahigh resolution, all use cathode ray tube, the electron gun of the cathode ray tube that these are traditional, under the situation of colour picture, comprise one group in horizontal direction the negative electrode of linear array (promptly produce red respectively, green, three negative electrodes of electron beams such as indigo plant), the electronics that this cathode emission goes out will form three-beam electron-beam in this electron gun, after the main lens that this three-beam electron-beam is formed via focusing electrode and anode again focuses on, be projected on the video picture screen, and after scanning, on the video picture screen, constitute coloured image.Review monochromatic cathode ray tube, an electron beam is then only arranged, be projected on the screen.
Conventional cathode ray tube adopts three locate modes of assembling fixture when the pole piece of assembling electron gun, it is provided with the through hole that passes through for three-beam electron-beam on each pole piece, and so three through holes with each pole piece are set on three locating shafts of assembling fixture.But, the through hole of these pole piece both sides is that the aperture of eccentric orfice or through hole is during greater than the locating shaft diameter of axle, the space that is produced between the locating shaft of aperture and assembling fixture, can cause pole piece to produce the rotation shift phenomenon because of this space, cause assembly precision bad, the three-beam electron-beam of electron gun can't accurately be incident upon on the video picture screen.
