Description

A kind of joints of optical fibre

Technical field

This utility model is related to the joints of optical fibre and in particular to a kind of joints of optical fibre.

Background technology

In recent years global information technology high-speed development, communication bandwidth network speed improves constantly, as the important carrier in broadband：Optical fiber Communication technology, even more high speed development.The joints of optical fibre are docking accurate for two end faces of optical fiber, make launching fiber defeated The luminous energy going out is coupled to greatest extent and accepts in optical fiber.

The existing joints of optical fibre connect defective tightness, there is the silver that insertion core end face and optical fiber damage in installation process OK, and dust-proof effect difference shortcoming.

Utility model content

The purpose of this utility model：There is provided a kind of joints of optical fibre, solution insertion core end face in installation process is easily impaired, And the problem of dust-proof effect difference.

For achieving the above object, a kind of joints of optical fibre of this utility model, including attachment means and plug assembly, described company Connection device and plug assembly are detachable connection, and attachment means are inserted respectively into plug assembly two ends, make two of optical fiber to hold Face is docked；

Described attachment means include protective case, ceramic insertion core and end cap, described protective case, and it is wrapped in outside optical fiber, protection It is provided with locking groove on set；A ceramic insertion core part is fixedly installed in protective case, another part exposed outside protective case, end Lid parcel ceramic insertion core, the afterbody of end cap is fixed on inside protective case using the first spring, and the head of end cap corresponds to ceramic insertion core Position setting optic fibre hole, so that ceramic insertion core can be stretched out by optic fibre hole；

Described plug assembly includes main body and retainer, and described main body is symmetrical structure, its internal setting ceramic insertion core hole, Ending cover hole and protective case hole, when union joint insertion body interior, each several part is corresponding to be placed in the hole；The center of main body About two symmetrical projections of setting；Described retainer has two, corresponding locking groove, and be respectively symmetrically is arranged on body top Two ends, retainer includes scotch, connecting rod, second spring and pulling block, the two ends of described connecting rod fixed stop block and drawing respectively Block, second spring is enclosed within connecting rod, scotch positioned at body interior.

Preferably, the lower surface of described scotch is acute angle with the angle of the longitudinal axis of main body.

Preferably, being provided with locating slot in described main body, corresponding protective case is provided with positioning convex.

Compared with prior art, the utility model has the advantages that：End cap protection ceramic insertion core so as to injury-free, is installed Convenient, attachment means are completely embedded with plug assembly, good dustproof effect.

Brief description

By the description to this utility model embodiment referring to the drawings, of the present utility model above-mentioned and other mesh , feature and advantage will be apparent from, in the accompanying drawings：

Fig. 1 is structural representation of the present utility model；

Fig. 2 is the structural representation of this utility model attachment means；

Fig. 3 is the structural representation of this utility model plug assembly.

Specific embodiment

It is more fully described various embodiment of the present utility model hereinafter with reference to accompanying drawing.

As shown in Figure 1, a kind of joints of optical fibre, include attachment means 1 and plug assembly 2, described attachment means 1 with slotting Connection device 2 is detachable connection, and attachment means 1 are inserted respectively into plug assembly 2 two ends, makes two end face docking of optical fiber；

As shown in Figure 2, described attachment means 1 include protective case 11, ceramic insertion core 12 and end cap 13, described protective case 11, it is wrapped in outside optical fiber 4, and protective case 11 is provided with locking groove 111；Ceramic insertion core 12 part is fixedly installed on protection In set 11, another part is exposed, and outside protective case 11, end cap 13 wraps up ceramic insertion core 12, and the afterbody of end cap 13 utilizes the first spring 131 are fixed on inside protective case 11, the position setting optic fibre hole 132 of the corresponding ceramic insertion core 12 of head of end cap 13, so that pottery is inserted Core 12 can be stretched out by optic fibre hole 132；

As shown in Figure 3, described plug assembly 2 includes main body 21 and retainer 22, and described main body 21 is symmetrical structure, its Internal setting ceramic insertion core hole, ending cover hole and protective case hole, when attachment means 1 insertion main body 21 inside, each several part is corresponding It is placed in the hole；The center of main body 21 arranges about two symmetrical projections 23；Described retainer 22 has two, corresponding Locking groove 111, the two ends being arranged on main body 21 top being respectively symmetrically, retainer 22 includes scotch 221, connecting rod 222, second Spring 223 and pulling block 224, two ends fixed stop block 221 and the pulling block 224 respectively of described connecting rod 222, second spring 223 is enclosed within On connecting rod 222, scotch 221 inside main body 21.

In order that during attachment means 1 insertion plug assembly 2, convenient, the lower surface of described scotch 221 and main body 21 Longitudinal axis angle be acute angle.

Locating slot 3 is provided with described main body 21, corresponding protective case 11 is provided with positioning convex 31.

End cap 13 is connected using the first spring 131 with protective case 11, and end cap 13 parcel ceramic insertion core 12 is effectively protected The end face of ceramic insertion core 12；During connection, attachment means 1 are inserted, raised 23 block end cap 13 and compress the first spring 131, the One spring 131 drives end cap 13 mobile, so that ceramic insertion core 12 is exposed, and scotch 221 falls in locking groove 111 so as to fix tightly Gu, during dismounting, pull pulling block 224, and extract attachment means 1, the first spring 131 recovers elasticity, so that end cap 13 is ejected, and wraps up Ceramic insertion core 12, protects ceramic insertion core 12.

Finally it should be noted that：Obviously, above-described embodiment is only intended to clearly illustrate this utility model example, And the not restriction to embodiment.For those of ordinary skill in the field, also may be used on the basis of the above description To make other changes in different forms.There is no need to be exhaustive to all of embodiment.And thus The obvious change amplified out or change among still in protection domain of the present utility model.
