Referring to fig. 8 to 11, the principle of the fiber holding tool of the present application will be described below with reference to the drawings.
The existing optical fibers are divided into point-bonding mesh optical fibers and net-bonding mesh optical fibers, and the positions of bonding points of the two optical fibers are different due to different bonding modes, so that different effects can be achieved when the two optical fibers are placed in a clamp.
The bonding points of the point-bonding net-shaped optical fiber are relatively fixed and regular, and when the point-bonding net-shaped optical fiber is used:
the first step is as follows: arranging the point-bonded netted optical fiber, and paving the point-bonded netted optical fiber in the V-shaped groove part of the optical fiber accommodating groove. At this time, the point-bonded mesh optical fibers are placed in the V-groove portion 31, and the point-bonded mesh optical fibers are arranged flatly and fully in the V-groove portion 31 by hand, at this time, because the point-bonded mesh optical fibers are 6 groups of optical fibers formed by bonding two by two, and the diameter of the optical fibers is 200 μm, 12 optical fibers cannot fall into the V-groove of the V-groove portion 31, but a group of optical fibers bonded together cannot fall into the same V-groove 4, and a group or bonded point of optical fibers can be located on the V-groove connecting portion 41.
The second step is that: the first cover 21 is closed with the main body 1, and the first elastic body 211 presses the V-groove portion 32 to clamp the point-bonded optical fiber mesh on the V-groove portion 32.
When the first cover 21 is covered and connected with the main body 1, the first elastic body 211 presses the point-bonded mesh optical fiber.
The third step: the spot-bonded optical fiber not pressed by the first elastic body 211 is arranged so as to be spread over the smooth portion 31.
The fourth step: the second cover 22 is closed with the main body 1, and the second elastic body 221 presses the smooth portion 21 to clamp the spot-bonded optical fiber mesh on the smooth portion 21.
The second cover 22 is covered and connected with the main body 1, the second elastic body 221 presses the point-bonded mesh optical fiber on the smooth portion 32, and the whole point-bonded mesh optical fiber is clamped flatly.
At this time, the clamped point-bonded netted optical fiber further comprises a coating layer, so that the optical fiber welding work cannot be carried out, when the point-bonded netted optical fiber is placed on an optical fiber welding machine for optical fiber welding, the coating layer of the point-bonded netted optical fiber needs to be stripped, only the bare optical fiber is used, so that the clamped point-bonded netted optical fiber and an optical fiber clamping tool need to be placed in an optical fiber stripper together, the coating layer outside the optical fiber is stripped, in the stripping process, the stripper needs to draw the optical fiber on the optical fiber clamping tool to strip the optical fiber coating and the bonding part of the point-bonded netted optical fiber, although the point-bonded netted optical fiber can not fall into the V-shaped groove completely, however, the position is not greatly displaced, and the first elastic body 211 can clamp the point-bonded optical fiber mesh, and the point-bonded optical fiber mesh of the smooth portion 32 is sandwiched by the second elastic body 221, so that the second elastic body 221 can also have an effect of assisting clamping. After the point-bonded reticular optical fiber coating is stripped, the V groove connecting part 41 is sharp, bare fibers of the point-bonded reticular optical fibers can directly fall into the V groove 4 after the point-bonded reticular optical fibers are stripped, and then the clamped point-bonded reticular optical fibers are placed on the V groove of the optical fiber fusion splicer.
The net-bonded net-shaped optical fiber is in an irregular net shape, and the bonding points of the net-bonded net-shaped optical fiber can be bonded with a plurality of optical fibers, so that the bonded optical fibers cannot fall into the V-shaped groove inevitably during use. When in use:
the first step is as follows: arranging the net bonded net-shaped optical fiber, and paving the net bonded net-shaped optical fiber in the V-shaped groove part of the optical fiber accommodating groove.
Similarly, the net bonded mesh optical fibers are placed in the V-groove portion 31, and the net bonded mesh optical fibers are arranged flatly and fully in the V-groove portion 31 by hand, the diameter of a single optical fiber of the net bonded mesh optical fibers is smaller than the width of the V-groove 4, at this time, the single optical fiber can directly fall into the V-groove 4, but a plurality of bonded optical fibers may be located on the V-groove connecting portion 41, that is, the plurality of bonded optical fibers cannot fall into the V-groove.
The second step is that: the first cover 21 is closed with the main body 1, and the first elastic body 211 presses the V-groove portion 32 to clamp the adhesive mesh optical fiber on the V-groove portion 32.
When the first cover 21 is closed with the body 1, the optical fibers of the net-bonded netted optical fibers may be shifted to a larger position on the V-groove 31, and it is highly likely that a plurality of optical fibers are simultaneously located in the V-groove connecting portion 41 or a plurality of optical fibers are commonly located in the same V-groove, the effect of the first elastic body 211 clamping the net-bonded netted optical fibers may be reduced, the optical fibers simultaneously located in the V-groove connecting portion 41 or a plurality of optical fibers are commonly located in the same V-groove and are higher than the optical fibers directly falling into the V-groove 4, and the optical fibers directly falling into the V-groove 4 cannot be tightened by the first elastic body 211.
The third step: the adhesive net-like optical fibers not pressed by the first elastic body 211 are arranged so as to be spread over the smooth portion 31.
The fourth step: the second cover 22 is closed with the main body 1, and the second elastic body 221 presses the smooth portion 21 to clamp the adhesive mesh optical fiber on the smooth portion 21.
For the adhesive net-shaped optical fiber, the clamping function of the second elastic body 221 is very important, when the first cover 21 is covered and connected with the body 1, the second cover 22 is covered and connected with the body 1, the bottom surface of the smooth portion 32 is a flat bottom surface, and the adhesive net-shaped optical fiber does not have different heights in the smooth portion 32, so that when the second cover 22 is covered and connected with the body 1, the second elastic body 221 can clamp the adhesive net-shaped optical fiber on the smooth portion 32.
The clamped net-shaped optical fiber also comprises a coating which can not be used for optical fiber fusion, when the net-shaped optical fiber is placed on an optical fiber fusion splicer for optical fiber fusion, the coating page of the net-bonded netted optical fiber needs to be stripped, only the bare optical fiber is used, so the clamped net-bonded netted optical fiber and the optical fiber clamping tool need to be placed in the optical fiber wire stripper together to strip the coating outside the optical fiber, in the stripping process, the stripper needs to draw the optical fiber on the optical fiber clamping tool to strip the optical fiber coating and the bonding part of the net bonded netted optical fiber, the net bonded netted optical fiber can not fall into the V-shaped groove, and the first elastic body 211 cannot clamp the adhesive net-shaped optical fiber, at this time, the second elastic body 221 clamps the adhesive net-shaped optical fiber of the smooth portion 32, the optical fiber stripper can not generate the situation that a single optical fiber is separated from the net-bonded netted optical fiber due to the fact that part of the optical fiber cannot be clamped in the process of drawing the net-bonded netted optical fiber. After the net-bonded reticular optical fiber coating is stripped, the V groove connecting part 41 is sharp, the bare fiber of the net-bonded reticular optical fiber can directly fall into the V groove 4 after stripping, and then the net-bonded reticular optical fiber clamped by the optical fiber clamping tool is placed on the V groove of the optical fiber fusion splicer, and the interval between the net-bonded reticular optical fibers is adjusted to be the same as the interval between the optical fibers with the diameter of 250 mu m by the optical fiber clamping tool, so the net-bonded reticular optical fiber clamped by the optical fiber clamping tool can directly fall into the V groove of the optical fiber fusion splicer, and the net-bonded reticular optical fiber clamped by the optical fiber clamping tool can be compatible and adaptive with the original optical fiber fusion splicer.
The utility model discloses in, the operation order of first lid 21 and second lid 22 can not take place to reverse, reverses the back, and optic fibre is difficult for keeping the straight state of spreading V slot part 31 in V slot part 31, forms the optic fibre tip of highly different complicatedly, can cause the puzzlement to the work at back like this, takes place the condition of unable fusion splice optic fibre.
The detailed description of the embodiments of the present invention has been presented, and it will be apparent to those skilled in the art that the present invention can be modified and modified without departing from the principles of the present invention, and the modifications and modifications also belong to the protection scope of the claims of the present invention.
