Description
Technical field
It the utility model is related to the storage technical field of photodetector, and in particular to a kind of seal box of photoelectric detector.
Background technology
The principle of photodetector is to cause illuminated material electric conductivity to change by radiation.Photodetector is in military affairs
There is extensive use with the every field of national economy, be mainly used in radionetric survey and detection, work in visible ray or near infrared band
Industry automatically controls, Photometric Measurement etc., is mainly used in missile guidance, infrared thermal imaging, infrared remote sensing etc. in infrared band.Root
Mechanism according to mode difference in other words device work of the device to rdaiation response is different, and photodetector can be divided into two major classes：One
Class is photon detector, and another kind of is thermal detector.Temperature raises after thermal detector absorbs optical radiation energy based on material, from
And its electric property is changed, the maximum feature that it is different from photon detector is the wavelength non-selectivity to light radiation.
Photodetector needs to be placed in seal box when in applied to optical fiber temperature transducer system, but when in height
When in warm high humidity environment, existing seal box of photoelectric detector sealing property is poor, and vapor is easily invaded in box, and box body dissipate and
Anti-seismic performance is poor, can cause photodetector failure, damages photodetector.
A kind of seal box of photoelectric detector of application for a patent for invention (Application No. 201510943534.2) includes the first box body
With the second box body, first box body is provided with groove, and second box body is located in groove, and the side of first box body is closed
Page is connected with the first cover plate, and first cover plate is provided with the second locking device, and the bottom of the groove is placed provided with drier
Groove, second box body is interior to be provided with detector standing groove, and the bottom of the detector standing groove is provided with some passages, four institutes
State and support block is provided with passage, the bottom of second box body is provided with the limited block being connected with support block.The patent of invention Shen
The moisture in box body please is reduced merely with drier, sealing property is poor still to have vapor intrusion.
Therefore it is badly in need of providing a kind of sealing and perfect heat-dissipating, photodetector is fixed, the light of good damping effect
Electric explorer seal box.
Utility model content
The purpose of this utility model is the deficiency for existing seal box of photoelectric detector, there is provided a kind of sealing and radiating
Performance is good, and photodetector is fixed, the seal box of photoelectric detector of good damping effect.
The utility model provides following technical scheme：
Seal box of photoelectric detector, including box body, the lid that is placed on above the box body and located at the tray interior
Storage tank, the outer wall of the box body is provided with fin, beam, the box body is filled between the box body and the storage tank
Inwall be provided with some moisture absorption grooves, the upper surface of the box body is provided with first seal groove of circle, and the lid is provided with and described the
The second seal groove that one seal groove is engaged.
Preferably, the side wall of the storage tank is provided with 2 pairs of fixed blocks and rectangular shaped arrangement, the fixed block of same side
Between be provided with main limit rib, be provided with oblique limit rib between diagonal fixed block.Main limit rib and oblique limit rib can enter to photodetector
Line position puts fixation, prevents it from rocking.
Preferably, the shape of cross section of first seal groove is trapezoidal that the shape of cross section of second seal groove is
The sealing strip that shape is engaged is installed in rectangle, first seal groove and second seal groove.The first trapezoidal sealing
Groove good fixing effect, it can prevent sealing strip from misplacing or coming off, the sealing strip that the first seal groove, the second seal groove and shape match
It can make seal box that there is good sealing property.
Preferably, some fixing holes are provided with the outside of first seal groove, are fixed for lid and box body.
Preferably, porous carbon materials are filled with the moisture absorption groove, moisture pick-up properties is good.
Preferably, the inner surface of the lid is provided with hemispherical damping projection, has auxiliary cushioning effect, can protect
Photodetector.
The beneficial effects of the utility model are：
(1) the utility model provided with top be rectangle, bottom be trapezoidal different in nature sealing strip, can have the seal box
Good sealing effectiveness, prevent vapor from invading tray interior；The presence of moisture absorption groove can be in adsorption box body vapor, make light
Electric explorer is in dry environment.
(2) box body of the present utility model is provided with fin, can effectively radiate, and prevents photodetector is in high temperature from losing
Spirit.
(3) beam is filled between the utility model box body and storage tank, the vibrations from the external world can be mitigated, protects light
Electric explorer, extend its service life.
