Description
Technical field
The invention belongs to fiber plant technical field, is related to a kind of fiber optic protection cover structure.
Background technology
Optical fiber is one kind fiber made of glass or plastics, can be used as light conduction instrument.Bare optical fiber is generally divided into three
Layer：Center glass of high refractive index core, centre is low-refraction silica glass covering, and outermost is the resinous coat of reinforcement.Light exists
Fibre core transmits, when optical fiber is mapped to the angle of fibre core and outer bed boundary more than the critical angle for producing total reflection, the impervious boundary of light
It face, can all reflect, continue to forward in fibre core, and covering primarily serves the effect of protection.
The species of optical fiber is a lot, different according to purposes, required function and performance also difference.But for wired electricity
Depending on and communication optical fiber, its design and manufacture principle it is essentially identical, be embodied in (1) loss it is small；(2) there is certain bandwidth
And dispersion is small；(3) wiring is easy；(4) it is easy into system；(5) reliability is high；(6) it is relatively simple to manufacture；(7) several sides such as inexpensive
Face.But existing optical fiber is due to fibre-optical bending, extruding, the bad decay that can cause optical fiber of fiber alignment, in addition, when optical fiber is long
Between exposed phenomena such as easily causing weathering outside, influence the using effect of optical fiber, it is therefore desirable to which design is a kind of to be carried out with optical fiber
With the protective cover used.
The content of the invention
The present invention for existing optical fiber due to fibre-optical bending, extruding, the bad decay that can cause optical fiber of fiber alignment,
The deficiencies of have impact on the using effect of optical fiber, fiber optic protection cover structure is proposed, can further reduce the light decay of optical fiber, lift product
Overall performance, the service life of extended fiber.
Technical scheme：A kind of fiber optic protection cover structure, it is characterised in that：The fiber optic protection cover by housing and
Cover plate connects and composes, and the bottom of the housing is provided with guide groove, and the side of the guide groove is provided with connecting platform, the cover plate one
End is flexibly connected by hinge with guide groove upper end, and the cover plate other end is provided with binding groove, is provided with the binding groove tight
Firmware, the fastener are connected through the binding groove with connecting platform, and the end of the cover plate is provided with cover plate groove, the lid
The groove face of plate groove and guide groove is fitted and connected, and its upper surface and the upper surface of housing are flush after the cover plate closing.
The groove profile angle of the guide groove is 120 °.
The connecting platform is arranged on the centre position of guide groove groove face, and the bottom surface of connecting platform is parallel with housing bottom surface.
The binding groove is circular counter bore groove, and counterbore depth is more than the hex nut thickness of bolt.
The hinge is collectively formed by the bearing pin that is arranged on enclosure interior and the collar for being arranged on patch ends, the collar with
Bearing pin forms gap and coordinated.
The reach of the fastener is more than connecting platform to the height of cover plate.
Beneficial effects of the present invention are：A kind of fiber optic protection cover structure proposed by the present invention, protection cover structure is novel, opens and closes
Simple possible, structure are made up of housing and cover plate on the whole, and optical fiber is placed in protection cover structure, can effectively be prevented because of optical fiber
Bending, extruding, fiber alignment it is bad and caused by optical fiber attenuation, overall the using of effect lifting product is provided with by the protection device
Performance, the service life of extended fiber.
Brief description of the drawings
Fig. 1 is overall structure diagram of the present invention.
