Specific embodiment
Below in conjunction with accompanying drawing embodiment, the invention will be further described.
The voluntarily folding and unfolding fibre fiber storage cloth fibre device of one kind as shown in Figure 1 to Figure 3, including housing 4, at the two ends of the housing 4
Be provided with the Fiber trough 2,2-1 in crossing distribution, the Fiber trough 2,2-1 be bending it is rectangular-shaped, the two of each Fiber trough 2,2-1
Side carries semi arch.Natural torsion spends little, and caused damage when the effect of the semi arch can avoid away fibre.In described shell
By A, B assembly pulley 3,6 has been spaced in body 4, wherein B assembly pulleys 6 are arranged in housing 4 in the chute 5 of both sides, can enter line position
Move.A, B assembly pulley 3,6 described in the present embodiment is rotated relative to wheel shaft.The B assembly pulleys 6 are connected with a displacement control device,
Displacement control device described in the present embodiment, including reducing motor 9, the axis two ends of reducing motor 9 are by being provided with symmetrical receipts
The connection tension spring 7 of line 8 is strained at, is connected with B assembly pulleys 6 by tension spring 7.Wind on A, B assembly pulley of the present invention 3,6
There are jumping fiber or tail optical fiber 10, the fairlead 1,1-1 of the jumping fiber or tail optical fiber 10 respectively along the two ends of housing 4 draws embedded Fiber trough 2,2-1,
It is connected with fiber optic adapters or fiber plant interface by smooth vertical and horizontal cloth fibre by Fiber trough 2,2-1.After the completion of cloth fibre, by control
Reducing motor processed 9 is rotated, and will expose remaining jumping fiber or tail optical fiber voluntarily receives fine fiber storage on A, B axle assembly pulley 3,6, facilitates failure
Search.A, B assembly pulley 3,6 involved by the present embodiment is combined using multiple independent sheaves.A, B assembly pulley 3,6
On race be helicla flute.Fiber storage on the helicla flute that jumping fiber or tail optical fiber 10 be wrapped on A, B assembly pulley 3,6 can so be kept.
Fairlead 1,1-1 described in the present embodiment is provided in the center of housing 3.When cloth is fine, jumping fiber or tail optical fiber 10 are from fairlead 1 or 1-
Draw in 1, using the plug on jumping fiber or tail optical fiber 10 and corresponding fiber optic adapters or the similar shape interface on fiber plant
It is attached.In the present embodiment, the voluntarily physical length of folding and unfolding jumping fiber or tail optical fiber 10, equal to jumping fiber or tail optical fiber in the He of A assembly pulleys 5
The product of two times of movable distances between A assembly pulleys 5 and B assembly pulleys 11 of the number of turns wound on B assembly pulleys 11.During operation,
One end of Wang meanings drawing jumping fiber or tail optical fiber 10, B assembly pulleys 6 all can be in rotary moving to the direction of A assembly pulleys 3, rotates in B assembly pulleys 6
While mobile, synchronous drive is tightened up bracing wire 8 and is moved, and the passive rotate counterclockwise of the effect two end axles of reducing motor 9 tightens up bracing wire 8
Lengthened, B assembly pulleys 6 are in rotary moving towards the close direction of A assembly pulleys 3, so as to discharge jumping fiber or tail optical fiber 10.When jumping fiber or tail
Fine 10 in traction process or when stopping drawing, reducing motor 9, tightens up under bracing wire 8, the collective effect of tension spring 7, makes to tighten up
Bracing wire 8 is in all the time passive tensioning state (as shown in Figure 1), and reducing motor 9 is in holding state.When reclaiming, tighten up jumping fiber
Or during tail optical fiber 10, in the presence of tension spring 7, remaining jumping fiber or tail optical fiber 10 is slightly reclaimed, relieve that to tighten up bracing wire 8 passive
Make jumping fiber or tail optical fiber 10 lax under tension force effect, play reducing motor 9 and rotate, bracing wire 8 is tightened up, under the driving of reducing motor 9
Work, B assembly pulleys 6 are in rotary moving away from the direction of A assembly pulleys 3, so that jumping fiber or tail optical fiber 10 are tightened up, it is achieved thereby that jumping fiber
Or the recovery of tail optical fiber 10, to tighten up after A, B assembly pulley 3,6 carries out fiber storage after jumping fiber or tail optical fiber 10, reducing motor 9 quits work.
In above-mentioned, mentioned A, B assembly pulley 3,6 in addition to being combined using multiple independent sheaves, it is also an option that
By the assembly pulley that multiple races are distributed on an overall pulley.
In above-mentioned, mentioned fairlead 1,1-1 can also be near Fiber trough 2,2-1 in addition to centrally disposed
The cross Fiber trough both sides of formation symmetrical fairlead is distributed with.
In above-mentioned, the pulley combination quantity of A, B assembly pulley 3,6 determines according to the length of jumping fiber or tail optical fiber 10.
The fiber optic adapters that the present invention is referred to, including some module array assemblys, have and not similar shape in each module
Socket on the circle of shape, square toes jumping fiber or tail optical fiber, and the both sides of each module have symmetrical half slot, each half slot phase
Fiber passage to composition circle, square toes jumping fiber or tail optical fiber.The injury for avoiding overbending from causing jumping fiber or tail optical fiber.
Fig. 4 gives another embodiment.According to above-mentioned application characteristic, it is to be mounted with that a lock is fine on the basis of Fig. 1
Device C.The fine device C of lock that the present invention is provided is arranged on housing 4 on the fairlead 1,1-1 at two ends.Lock fibre device C of the present invention,
It is nested together each other including inside and outside horn body 11,12, is connected with housing 4 by being provided with support spring 14 on inside trumpet body 11
The outer horn body 12 of effect is embedded on fairlead 1,1-1, with closure on inside trumpet body 11, has one to draw fine clamping hole 13 thereon.
The voluntarily retraction of jumping fiber or tail optical fiber is discharged for limiting, and can naturally pull jumping fiber or tail optical fiber.When jumping fiber or tail optical fiber 10 are leading
During drawing or when stopping drawing, in the fine device C of lock, reducing motor 9, under tightening up bracing wire 8, the collective effect of spring 7, make to tighten up drawing
Line 8 is in all the time passive tensioning state (as shown in Figure 1), and reducing motor 9 is in holding state.When to reclaim, tighten up jumping fiber or
During tail optical fiber 10, the fine device C of lock is unclamped, in the presence of tension spring 7, remaining jumping fiber or tail optical fiber 10 is slightly reclaimed, relieve receipts
Straining at makes jumping fiber or tail optical fiber 10 lax under the effect of the passive tension of line 8, play reducing motor 9 and rotate, and bracing wire 8 is tightened up, in the electricity that slows down
Work under the driving of machine 9, B assembly pulleys 6 are in rotary moving away from the direction of A assembly pulleys 3, so that jumping fiber or tail optical fiber 10 are tightened up, from
And the recovery of jumping fiber or tail optical fiber 10 is realized, when jumping fiber or tail optical fiber 10 are tightened up, reducing motor 9 quits work, while pressing lock
Fine device C, keeps the fiber storage state of A, B assembly pulley 3,6.
The key for implementing the present invention is connected for optical cable and optical cable, optical cable and fiber plant, fiber plant and fiber plant
In termination process, voluntarily folding and unfolding fibre, fiber storage and the cloth fibre of jumping fiber and tail optical fiber is realized.Improve optical cable to set with optical cable, optical cable and optical fiber
The cloth fibre environment interweaved in length and breadth in standby, fiber plant and fiber plant connection procedure, improves comprehensive cloth fibre efficiency.
