According to the outer skin fastening device for the small optical cable, a fully hand pressure technology is adopted, so that the outer skin of the optical cable can be firmly fixed without any special tool, the pull-out force is more than 10N, the fastening of the optical cable is safe, the optical fiber is not damaged, no extra insertion loss is produced, the optical cable is protected against potential damage risks, the operation is simple, and the construction intensity is small.
Description
Technical field
The present invention relates to a kind ofly for small optical cable device for fastening sheath, be specifically related to a kind of optical cable fastener.
Background technology
Along with the fiber-to-the-home coverage density of FTTH is more and more high, in corridor junction box, coupling box, Cabinet during fibre junction, the optical cable specification tightening up is more and more less, wherein optical cable crust is that 0.25mm is defined as small optical cable between 1.2mm, for these small optical cable crusts are fastening, do not have a good method, for tightening up of optical cable crust, mainly contain two kinds of methods at present:
The first is by V-type groove and gland afterbody, arc groove being set respectively, during work, in the optical fiber in compressing V-type groove, dwindles arc groove space, and auxiliary sturdy optical cable coating, does not have the effect of tightening up; The second is to push ejector sleeve to depress suspended block, presses down optical cable coating tighten up by suspended block.
These the two kinds power that tighten up that tighten up mode are all no more than 5N, and first kind of way is because the deflection of optical cable coating does not reach locking amount, so tighten up power deficiency; The stroke that presses down of second way suspended block is subject to ejector sleeve and imports drag effects, arranges too highly, pushes ejector sleeve power too large, low not reaching is again set and tightens up object.
Summary of the invention
Technical matters to be solved by this invention is for above-mentioned the deficiencies in the prior art, provide a kind of for small optical cable device for fastening sheath, comprise caudal peduncle, ejector sleeve, at described caudal peduncle middle part, be symmetrical arranged a pair of pressing tongs, at the same angle direction of pressing tongs, two circular arcs are set and cut platform, guiding conical ring is set in front hole; In ejector sleeve, setting cuts with the circular arc on caudal peduncle the circular arc grooving that platform matches; Fastener mainly by ejector sleeve advance, rotary manipulation progressively goes forward one by one and depresses the pressing tongs on caudal peduncle, makes pressing tongs embed optical cable crust, fixes optical cable; This structure can repeat to open and use.
For solving the problems of the technologies described above, the present invention just technical scheme of use is: a kind of for small optical cable device for fastening sheath, comprise and there is the caudal peduncle of at least one pair of pressing tongs and be enclosed within ejector sleeve on described caudal peduncle and that push described pressing tongs, it is characterized in that: on described caudal peduncle, be also provided with at least one pair of circular arc and cut platform, this circular arc is cut platform and pressing tongs same angle setting on caudal peduncle axis direction, and described circular arc is cut platform, and in a side of caudal peduncle circumferencial direction, the radius to opposite side increases progressively; In ejector sleeve, setting cuts with the circular arc on caudal peduncle the circular arc grooving that platform matches.
The rail groove of controlling rotary angle position is also set on described caudal peduncle, coordinates with the axis of an orbit of ejector sleeve front end, the angle on described rail groove opening both sides is 90 °.
Pressing tongs on described caudal peduncle is connected by the muscle that floats with caudal peduncle.
Described ejector sleeve front end arranges the importing conical surface.
In described caudal peduncle front hole, guiding conical ring is set.
Optical cable sheath fastener of the present invention adopts full hand technology, does not use any specific purpose tool, just can firm fixedly optical cable crust, pulling-out force is greater than 10N, and the fastening safety of optical cable can not produce injury to optical fiber, can not produce extra Insertion Loss, protection optical cable reduces latent lesion risk; Simple to operate, construction intensity is little.
Compared with prior art, tool of the present invention has the following advantages:
Optical cable sheath fastener of the present invention fixedly crust be by pressing tongs, to snap in crust mode to realize, solved tightening up of some special soft type optical cable crust, snap in stroke large, anti-pulling-out force is greater than 10N.
2. optical cable sheath fastener of the present invention is fixedly during optical cable crust, due to what adopt, is that multiple step format pushes away and revolves combination and tighten up mode, and compact conformation, is easy to realize miniaturization, microminiaturization.
3. device for fastening sheath pulling-out force of the present invention is large, can not produce injury to optical fiber, can not produce extra Insertion Loss, and protection optical cable reduces latent lesion risk.
4. optical cable sheath fastener of the present invention adopts full hand technology, and optical cable crust clamping mode is simple, reliable.
