Abstract
The utility model is specifically related to a kind of lighning proof type optical receiver that cable television system uses.Object is to provide the high lighning proof type optical receiver of a kind of fail safe, comprise inner housing, shell body and optical receiver operational module, described optical receiver operational module is arranged in inner housing, described shell body is arranged on outside inner housing, described shell body is arranged at intervals with two cube electrode sheets, described electrode slice upper end is positioned at outside shell body, lower end is between inner housing and shell body, lightning protection component is provided with between described electrode slice, lightning protection component is between inner housing and shell body, gap filling between described inner housing and shell body has fluid sealant, the input of optical receiver operational module and output stretch out the outside of shell body.When occurring when being struck by lightning, accumulation is also outwards transfer in the projection of electrode slice, and avoid and cause damage to optical receiver, such optical receiver just can adapt to multiple environment for use, is beneficial to popularization.
Description
Technical field
The utility model belongs to optical communication equipment field, is specifically related to a kind of lighning proof type optical receiver that cable television system uses.
Background technology
In fiber optic communication systems, the task of optical receiver is with minimum additional noise and distortion, recover the information entrained by light carrier after Optical Fiber Transmission, therefore the output characteristic concentrated expression performance of whole optical fiber telecommunications system of optical receiver.The light signal that optical sender is launched after transmission, not only amplitude fading, and impulse waveform also broadening, the effect of optical receiver is exactly detect the faint optical signal through transmission, and amplify, shaping, regeneration former signal transmission.
The optical receiver function of prior art is simple, and it is unreliable to run, when optical receiver is placed in field, often easily break by thunder and lightning, maintenance cost is higher, and useful life is short.
Utility model content
The purpose of this utility model is to provide the high lighning proof type optical receiver of a kind of fail safe.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of lighning proof type optical receiver, comprise inner housing, shell body and optical receiver operational module, described optical receiver operational module is arranged in inner housing, described shell body is arranged on outside inner housing, described shell body is arranged at intervals with two cube electrode sheets, described electrode slice upper end is positioned at outside shell body, lower end is between inner housing and shell body, lightning protection component is provided with between described electrode slice, lightning protection component is between inner housing and shell body, gap filling between described inner housing and shell body has fluid sealant, the input of optical receiver operational module and output stretch out the outside of shell body.
Preferred: described inner housing and shell body have a common bottom surface, and the input of optical receiver operational module and output from then on bottom surface stretch out.
Preferred: described electrode slice is arranged perpendicular to the outer wall of the shell body at its place.
Preferred: described electrode slice upper end is provided with arc-shaped convex, the projection on two electrode slices is oppositely arranged.
Preferred: described shell body outer wall is coated with fireproof paint.
The utility model has following beneficial effect: use such lighning proof type optical receiver, can adapt to multiple environment, even if also do not worry that thunderbolt causes damage to the inner member of optical receiver in the wild, ensures the normal operation of whole optical communication network.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
A kind of lighning proof type optical receiver as shown in Figure 1, comprise inner housing 2, shell body 1 and optical receiver operational module 3, described optical receiver operational module 3 is arranged in inner housing 2, described shell body 1 is arranged on outside inner housing 2, inner housing 2 and shell body 1 have a common bottom surface, the input of optical receiver operational module 3 and output inner housing 2 and the common bottom surface of shell body 1 are stretched out, optical receiver operational module 3 comprises photodiode, trans-impedance amplifier, LED display module and central control unit, its concrete layout is not the core content of this patent, those skilled in the art can realize with reference to prior art.
Described shell body is arranged at intervals with two cube electrode sheets 6, described electrode slice 6 upper end is positioned at outside shell body 1, lower end is between inner housing 2 and shell body 1, electrode slice 6 is arranged perpendicular to shell body 1, described electrode slice 6 upper end is provided with arc-shaped convex, and the projection on two electrode slices 6 is oppositely arranged, and the electric charge of whole like this lightning protection optical receiver can focus in the arc-shaped convex of electrode slice 6, outwardly shift, effectively avoid optical receiver to be struck by lightning.Lightning protection component 7 is provided with between described electrode slice 6, lightning protection component 7 is between inner housing 2 and shell body 1, lightning protection component 7 is arranged between inner housing 2 and shell body 1, like this when being struck by lightning generation, the high voltage produced by thunderbolt forms circular arc around electric discharge by the arc-shaped convex be oppositely arranged, high voltage is discharged rapidly, reduces high-tension electricity and enter in shell body 1.Two power on, and projection that pole piece 6 upper end is oppositely arranged also can be other shape, such as " V " type, T-shape or zigzag etc., when being struck by lightning generation, the high voltage produced by thunderbolt to be tapered off to a point electric discharge by the V shape projection be oppositely arranged, and high voltage is discharged rapidly and avoids causing damage to optical receiver.
Gap filling between described inner housing 2 and shell body 1 has fluid sealant 4; be coated with fireproof paint 5 outside shell body 1 simultaneously; even if occur that lightning voltage is too high like this to be punctured by lightning protection component 7, also can not there is the situation of optical receiver catching fire, further the safety of protection optical receiver.
Claims (5)
1. a lighning proof type optical receiver, it is characterized in that: comprise inner housing, shell body and optical receiver operational module, described optical receiver operational module is arranged in inner housing, described shell body is arranged on outside inner housing, described shell body is arranged at intervals with two cube electrode sheets, described electrode slice upper end is positioned at outside shell body, lower end is between inner housing and shell body, lightning protection component is provided with between described electrode slice, lightning protection component is between inner housing and shell body, gap filling between described inner housing and shell body has fluid sealant, the input of optical receiver operational module and output stretch out the outside of shell body.
2. a kind of lighning proof type optical receiver according to claim 1, is characterized in that: described inner housing and shell body have a common bottom surface, and the input of optical receiver operational module and output from then on bottom surface stretch out.
