Embodiment

Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model.

Refer to Fig. 1-Fig. 4, the utility model embodiment comprises:

A kind of fiber unit continues with movable stand, comprising: can movement on line slideway 9 adjustable for height support 1, for the chuck 2 of grip optical fiber unit and fixture 3.

Described support 1 comprises upper bracket 11 and lower carriage 12, and described upper bracket 11 is socketed with described lower carriage 12, and described upper bracket 11 is provided with a height adjustment knob 14, can be regulated the height of upper bracket 11 by height adjustment knob 14.

The top of described upper bracket 11 is fixed with a linking platform 15, and described fixture 3 is fixed on described linking on platform 15 with its chuck 2.Each fiber unit continues with the fixture 3 movable stand being fixed with more than 1 (comprising 1), and described chuck 2 is for fiber unit fixedly to be continued.

The bottom of described lower carriage 12 offers the groove 13 that can slide on line slideway 9, and described groove 13 matches with line slideway 9.

The connecting method of fiber unit is as follows:

1) the connectivity port place of fiber unit (A and B) to be connected identical for two model specifications is respectively divested the stainless-steel tube of suitable length, make connectivity port place respectively expose the optical fiber 4 of certain length.

2) on a fiber unit A, be inserted in outer tube 6, the port of a fiber unit A exposes about 1.5m after outer tube passes.

3) had by cover that fiber unit A of outer tube 6 fixing on fixed mount 7, the termination of outer tube 6 and the connectivity port near-end of a fiber unit A adopt movable stand of the present utility model to fix.

Be specially: appropriate location outer tube 6 being fixed on fixed mount 7 together with a fiber unit A, the right-hand member port of outer tube 6 to be positioned on fixed mount 7 and to be fixedly clamped, the termination of one fiber unit A is then positioned on the first movable stand 81, and be fixedly clamped by the chuck 2 at the first movable stand 81 top, the connectivity port near-end of a fiber unit A is fixing on the second movable stand 82.

4) link of another fiber unit B adopts some movable stands of the present utility model to fix.

Be specially: the link of another fiber unit B is placed on successively on the 3rd movable stand 83, the 4th movable stand 84, the 5th movable stand 85, and all compress with the chuck 2 on movable stand.

5) to the appropriate location, port to be connected of to be connected two stainless-steel tube fiber units (A, B), the stainless-steel tube detaching of fractureing respectively abandons, the optical fiber 4 exposed; Treated optical fiber 4 being penetrated the interpolation pipe 5 through polishing smooth process, avoiding making in bond process and scratch or cut off optical fiber 4, and carry out with stainless-steel tube fiber unit after interpolation pipe 5 being filled in the stainless-steel tube mouth of pipe place correct position crimp and fix.

6) optical fiber splicer is adopted to carry out welding after end face pre-service being carried out at the optic fibre end position of to be connected two fiber units (A and B).

7) to the optical fiber coating coating after welding, ultraviolet light polymerization and tension force screening is carried out.

8) outer tube 6 be inserted in advance is moved to fusion point place, and fill fine cream, behind the position of adjustment outer tube 6, outer tube and the lap position of stainless-steel tube fiber unit are carried out crimp and fix;

Be specially: (I) is after whole fibre junction point loss detection is qualified, by the 3rd movable stand 83, the 4th movable stand 84, the 5th movable stand 85 to the distal direction synchronizing moving of another fiber unit B, after making that the optical fiber after welding is approximate and being in exceptionally straight state, 3rd movable stand 83, the 4th movable stand 84, the 5th movable stand 85 are fixed, the excess fiber length in guaranteeing the excess fiber length of joint and producing in fiber unit is consistent again;

Stationary fixture 71 on fixed mount 7 then all unclamps by (II), remove the second movable stand 82, level holds the first movable stand 81 of outer tube 6 to the direction moving clip of another fiber unit B, until the external port of outer tube 6 flushes with the external port of interpolation pipe 5, in the process, the left mouth of pipe of outer tube 6 often through a stationary fixture 71, all needs this stationary fixture 71 to compress on fixed mount 7, guarantee that outer tube 6 is in the process of movement, a fiber unit A can not move thereupon;

The slow moving clip in direction that (III) continues horizontally another stainless-steel tube fiber unit B holds the first movable stand 81 of stainless steel outer sleeve pipe 6, manually injects fine cream simultaneously, until the external port of outer tube 6 holds interpolation pipe external port place near B, stops injecting fine cream;

(IV) then removes the 3rd movable stand 83, according to the method in step (III), the slow moving clip in direction continuing horizontally another fiber unit B holds the first movable stand 81 of outer tube 6, until one section of optical fiber after welding is in outer tube 6 middle, keep both sides symmetrical, the more all stationary fixtures 71 on fixed mount 7 are compressed; Crimp with a stainless-steel tube fiber unit A overlap fixing to outer tube 6 again, identical operation is also done to another fiber unit B, to complete continuing of fiber unit.

The joint adopting the method to make firmly, reliably, tensile strength is large, contact loss is low, can to continue lengthening to fiber unit as required, produce the fiber unit of large length, meet and make the needs of large length submarine optical fiber cable or optoelectronic composite cable, submarine optical fiber cable or optoelectronic composite cable when prepared by armouring and cable laying operation time also can pick up speed.

The utility model discloses a kind of fiber unit and continues with movable stand, by adopting moveable, adjustable for height support, before armouring, fiber unit being continued lengthening, facilitating cable laying operation and maintenance, and improve connecting quality and efficiency, reduce labour intensity.

The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model instructions and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
