Description
Technical field
The utility model relates to the electric vacuum display device field, is specially the airborne electron gun for display tube of looking squarely of a kind of high brightness, ultrashort type.
Background technology
Head-up display fire control system is a requisite weaponry in the modernized opportunity of combat, and it then is its core display device that high brightness is looked squarely display tube.Information is attacked in various flights, navigation information, the aiming of atmosphere data, computer input information, inertial navigation system, radar, fire control computer and the output of other airborne equipment for it and other operation information is accurate, clear with the form of high brightness, high-resolution character, image, be shown in pilot's dead ahead intuitively, image in the infinity, thereby correctly instruct the pilot to finish various flight combat duties.
Look squarely display tube and be operated in high environment illumination plane and carry under the situation, require its positioning accuracy can a bit change not arranged because of extraneous harsh conditions.This mechanical strength and structural strength to the electron gun parts looking squarely pipe and adopt has higher requirement, so that bear the examination of various adverse circumstances tests.
The utility model content
The purpose of this utility model provides a kind of airborne electron gun for display tube of looking squarely, and can satisfy the requirement of opportunity of combat under varying environment with mechanical strength and the structural strength of guaranteeing electron gun.
In order to achieve the above object, the technical scheme that the utility model adopted is:
A kind of airborne electron gun for display tube of looking squarely, include mounting cover, be connected with the electron gun modulation grid of tubular in the middle of the described mounting cover, it is characterized in that: have a plurality of glass poles that are installed on the mounting cover to be clamped in outside the described electron gun modulation grid, be provided with gun cathode in the described electron gun modulation grid, the electron gun modulation grid is outside equipped with intensifying ring, electron gun modulation grid rear is provided with a plurality of stem stems, there is filament to pass in the stem stem, gun cathode in described filament and the electron gun modulation grid is electrically connected, also be connected with the electron gun focusing utmost point that is positioned at electron gun modulation grid the place ahead on the described mounting cover, described electron gun focusing utmost point center has the current limliting fenestra and is communicated with described electron gun modulation grid, electron gun focusing utmost point interlude is a bottleneck, the spring support of band claw type spring is arranged, and the claw type spring of described spring support is tight against at described electron gun focusing utmost point Bottle Neck Road.
Described a kind of airborne electron gun for display tube of looking squarely, it is characterized in that: described a plurality of stem stems are installed in respectively on the bonding jumper, and the filament in the stem stem is fixed in the bonding jumper.
The utility model constitutes cloudy lamp assembly by filament and gun cathode, in the middle of the electron gun grid is clamped in by glass pole.Adopt bonding jumper to reinforce to the filament in the stem stem simultaneously.Outside whole electron gun, can put glass-tube, and employing glass-tube inwall graphite is as the last anode of electron gun, the extremely middle Bottle Neck Road of electron gun focusing adopts spring support, the inner surface strong bonded of the extremely middle Bottle Neck Road of the claw type spring of spring support and electron gun focusing makes whole electron gun utilize the glass bulb of graphite and spring support and outside to form integral body together.
The utility model has adopted cloudy lamp assembly and electron gun consolidation process, not only guaranteed display tube high brightness, high definition, but also guaranteed high strength, the high reliability of display tube.The electron gun focusing pole tension only has 0～400V.The low use that focuses on voltage has reduced system arcing source, has improved the stability of system greatly.
