Abstract
The utility model discloses an external overall structure of an infrared image converter tube. The external overall structure is mainly used for the assembly type structure of the infrared image converter tube. The main technical scheme is that a completely produced infrared image converter tube and a completely produced power supply body are installed in a plastic tube through clamping grooves, the back part of the infrared image converter tube is equipped with a rubber pad, the fixed connection is completed finally through the clamping groove and a thread, and the low voltage input end and the high voltage input end of the power supply are respectively connected with the cathode and the anode of the infrared image converter tube. According to the external overall structure, tests show that the phenomena of difficult adjustment in overall assembly, inconvenient repair and easy damage of the infrared image converter tube of an infrared night vision instrument are overcome fundamentally, the production efficiency is effectively raised and the cost is reduced.
Description
Technical field
the utility model belongs to a kind of external structure of photoelectric tube, is mainly used in a kind of external overall structure of infrared image converter tube.
Background technology
infrared image converter tube (see figure 1) is comprised of cathode disc 1, negative electrode slide 2, photocathode face 3, negative electrode urceolus 4, negative electrode inner core 5, glass cylinder 6, shielding cylinder 7, electrode cap 8, cone electrode 9, anode urceolus 10, anode disc 11, anode slide 12, phosphor screen 13 etc.Its operation principle: when infrared radiation image incides photocathode face 3, photocathode becomes infrared image into electronic image, through electron-optical system, by electronic image under the electric field action of high pressure 12KV, after strengthening, be delivered on phosphor screen 13, phosphor screen becomes electronic image visible optical imagery again, for eye-observation.The infrared viewing device that it assembles as core component, detector, identifier etc., be mainly used in night observation, nighttime driving, scientific research, criminal case scouting etc.
existing infrared image converter tube is as the individual components of a standard, and in order to guarantee insulating properties, its external overall structure normally, after infrared image converter tube is connected with power supply, is fixed with silicon rubber embedding, is similar to cylindric.Although this structure has guaranteed its insulating properties, substantially meet instructions for use, can not guarantee the consistency of optical axis and the embedding structure axis of infrared image converter tube, deviation is larger, when infrared viewing device final assembly, to correction, brings certain difficulty.Power supply breaks down in the time of need to repairing, and integral demounting, causes sometimes the damage to infrared image converter tube.Overall structure inner space silicon rubber filling, because silicon rubber is acid, of long duration, just can corrode the metal part of infrared image converter tube, causes infrared image converter tube to scrap.The power supply of external structure times pressing plate and oscillating circuit do not integrate, and separately connect, and cause structural volume large, are inconvenient to carry.Therefore improve the structure of this external overall encapsulation type, imperative.
Utility model content
the main technical problems to be solved in the utility model and object are: the deficiency existing according to the existing external overall structure of infrared image converter tube, design a kind of outside assembly type overall structure, adjustment difficulty, inconvenient maintenance while fundamentally overcoming final assembly, easily damage the phenomenon of infrared image converter tube.Reach and enhance productivity, reduce costs, further ensure the capability and performance of infrared image converter tube.
main technical schemes of the present utility model: the external overall structure of infrared image converter tube comprises infrared image converter tube, plastic tube tube, power source body, lid, rubber blanket, high-voltage output end, low pressure input, concrete structure: the infrared image converter tube of making completion is arranged in plastic tube tube by middle part draw-in groove, power source body packs in plastic tube tube by edge draw-in groove, at infrared image converter tube rear portion, pack rubber blanket into, finally by draw-in groove, be fixedly connected with lid with screw thread, the low pressure input of power supply is connected with anode position with the negative electrode of infrared image converter tube respectively with high-voltage output end.
the utility model proves by practical application: reach development object completely, externally, in integrally-built assembling, the axiality of plastic tube tube and infrared image converter tube is better, must not adjust, while carrying out final assembly, simply adjustment once, can be raised the efficiency and reach more than 3 times; During maintenance, need only directly open lid and just can check repairing, must wholely not dismantle, can not damage infrared image converter tube, and power failure generally just can user be repaired voluntarily; The power supply of external structure, becomes one power supply times pressing plate and oscillating circuit, has reduced like this volume, is easy to carry and assembles.
Accompanying drawing explanation
below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
fig. 1 is the structural representation of infrared image converter tube.
fig. 2 is structural representation of the present utility model.
fig. 3 is that the A-A of Fig. 2 is to cutaway view.
Embodiment
with reference to Fig. 2, main technical schemes of the present utility model is described: the utility model comprises infrared image converter tube B, plastic tube tube 14, power source body (power supply times pressing plate and oscillating circuit become one) 15, lid 16, rubber blanket 17, high-voltage output end 18, low pressure input 19, its structure: the infrared image converter tube B that makes completion is arranged in plastic tube tube 14 by middle part draw-in groove, power source body 15 packs in plastic tube tube 14 by edge draw-in groove, at infrared image converter tube B rear portion, pack rubber blanket 17 into, finally by draw-in groove, be fixedly connected with lid 16 with screw thread, the low pressure input 19 of power supply is connected with anode position with the negative electrode of infrared image converter tube B respectively with high-voltage output end 18.
above-described plastic tube tube 14, adopts ABS engineering plastics to produce.
the utility model is not only for the external overall structure of infrared image converter tube.Equally can be for similar light
the external overall structure of fulgurite, effect is identical.
