Abstract

The utility model provides an optical fiber protector to solve the problem that an optical fiber is easy to damage caused by that the turning radius of the optical fiber arranged in a protecting pipe can not be controlled in the prior art. The utility model which presents a shape of a chain in the main is composed of a plurality of wire clamps with same structures, and the wire clamps are mutually and orderly connected and can rotate opposite to each other, wherein, each wire clamp is composed of a bottom plate, and two side plates which extend upwards from both sides of the bottom plate, and a groove channel which can contain optical fibers is encircled jointly by the bottom plate and the side plates. Because the before-mentioned optical fiber protector can be bended at will, the turning radius of the optical fiber arranged in the protecting device can be effectively adjusted and controlled, and further, the damage of the optical fiber can not be caused.

Description

A kind of optical fiber protecting equipment

Technical field

The utility model relates to the plant equipment in the optical communication network, refers to a kind of optical fiber protecting equipment especially.

Background technology

Along with the continuous development of the big information transmission technology such as broadband connections technology, multimedia communication technology, legacy communications system can not satisfy described demand well, is developed well and application in the optical communication network that is based on optical transport technology.

In optical network communication system; optical fiber is indispensable as the media of transmission information; it has advantages such as capacity is big, the information velocity of propagation is fast; but optical fiber is again a kind of information of easy damage transmits cable, and often causes its performance decrease maybe can't use after damage, therefore; requirement in use must effectively be protected it; can not push, also not allow any scuffing, the minimum bending radius that just is connected in the optical fiber turning also has strict requirement.As seen, how optical fiber is effectively protected and just become the technical task that the industry utmost point need solve.

For addressing the above problem, industry has been released following several frequently seen optical fiber protecting equipment:

One, plastic cement pipe, concrete protection is: optical fiber is passed in the plastic cement pipe, and the position by constraint plastic cement pipe reaches the purpose of constraint optical fiber, and then make optical fiber can colligation in walking line process on the plastic cement pipe, reached the purpose of protection.

Two, plastic cement spiral pipe, concrete protection is: optical fiber is passed in corrugated tube,, reaches the purpose of constraint optical fiber by the position of constraint corrugated tube, the colligation of optical fiber also be indirectly-acting on plastic strip, thereby reach the protection purpose.

Three, corrugated tube, concrete protection is: optical fiber is passed in corrugated tube, by the position of constraint corrugated tube, thereby reach the purpose that retrains optical fiber, owing to periphery corrugated tube is arranged when colligation, so played protective effect.

Though more than three kinds of devices to a certain extent optical fiber has been played protective effect because the irrationality that itself structure exists, so all there is following shortcoming:

Above-mentioned three kinds of devices all adopt integral tubular structure, and then can not control the minimal curve radius of the optical fiber that is placed in one, and then under a lot of applied environments, make optical fiber damage easily;

Above-mentioned three kinds of protective devices are unfavorable for that optical fiber passes, particularly when optical fiber has joint, and more difficult passing.

Technology contents

The utility model provides a kind of optical fiber protecting equipment, to solve in the prior art owing to can not control optical fiber that the radius of turn that places protection tube optical fiber the causes problem of damage easily.

The technical solution of the utility model is achieved in that

A kind of optical fiber protecting equipment; roughly be chain form; form by the wire clamp that several structures are identical; be linked in sequence mutually between described several wire clamps and rotatable to each other; wherein; each wire clamp extends upward by base plate with from the base plate both sides and the biside plate that forms is formed, but described base plate surrounds the conduit of a receiving optical fiber with side plate.

Owing to adopt above-mentioned technical scheme, the utlity model has following advantage:

The optical fiber protecting equipment of chain structure, because can be arbitrarily crooked, place the radius of turn of protective device inner fiber so can regulate control effectively, and then can not cause the damage of optical fiber;

This protective device is not owing to adopt tubular structure, thus even when optical fiber has joint, also can easily be positioned in the protective device, and then make use convenient, quick.

Fig. 2 is the structural representation of wire clamp in the utility model.

Embodiment

Please refer to Fig. 1 and Fig. 2; the optical fiber protecting equipment that the utility model provides roughly is chain form; form by the wire clamp 1 that several structures are identical; 1 of described several wire clamp are linked in sequence mutually and are rotatable to each other; wherein; each wire clamp 1 extends upward by base plate 11 with from base plate 11 both sides and the biside plate 13 that forms is formed, but described base plate 11 surrounds the conduit of a receiving optical fiber with side plate 13.

But the inside top appropriate position of described each side plate 13 also bends inwards and is formed with a limit fibre and extrudes the outer boss 131 of wire clamp 1; Base plate 11 front ends of described each wire clamp 1 are provided with the card 111 that can socket-connect with last wire clamp 1 rear end; and base plate 11 rear ends of each wire clamp 1 are curved; and being provided with one can be for the groove 113 of back one wire clamp card, 111 grafting; utilize the socket relation of 113 of card 111 on the adjacent wire clamp 1 and grooves; not only several wire clamps 1 can be coupled together and form the optical fiber protecting equipment that the utility model provides; also can utilize its circular arc rotatable structural design that matches to guarantee to place the minimal curve radius of wire clamp 1 optical fiber well, and then optical fiber is not damaged.

In addition; on each wire clamp 1 of optical fiber protecting equipment of the present utility model two ends and middle appropriate location, also can add a cover a wire dress cover 2; the dual-side of this wire dress cover 2 is embedded in the biside plate top of described wire clamp 1; the optical fiber that described wire dress cover 2 is opposite in the wire clamp 1 provides constraints, and then optical fiber is controlled in the wire clamp 1 better.
