The kenel that wherein protective sleeve is convergent, is therefore being sheathed on after fiber connector, and the optical fiber in protective sleeve can be by the coated restriction of this convergent kenel, to reach the stable contiguity that increases optical fiber and fiber connector.
A structure-improved for fiber boot, is characterized in that:
It comprises
One fiber connector, its one end has an abutting end, on this abutting end outside surface and be provided with plural groove;
At least one optical fiber, one termination is located in this fiber connector;
One protective sleeve, its one end has a junction, and is sheathed on by this connecting portion on the abutting end of fiber connector;
It is mainly that the connecting portion that sees through protective sleeve one end is sheathed on the abutting end of fiber connector; with the contiguity of strengthening fiber connector and optical fiber; and see through set plural groove on abutting end outside surface and increase contact area and friction number; make protective sleeve being sheathed on after this abutting end, can increase the tightness degree of the two combination.
Wherein groove separately can be its one of convex body and shrinkage pool.
Wherein groove separately can be a uneven surface.
Wherein on abutting end, separately can be coated with an adhesion layer.
Wherein protective sleeve is the kenel of a convergent.
The beneficial effects of the utility model are: the utility model includes a fiber connector, at least one optical fiber and a protective sleeve; after seeing through on the abutting end that the connecting portion of protective sleeve one end is sheathed on fiber connector; by this to strengthen the contiguity of fiber connector and optical fiber; and see through set plural groove on abutting end outside surface and increase contact area and friction factor; make protective sleeve being sheathed on after this abutting end, can increase the tightness degree of the two combination.
The utility model is simple in structure, easy to maintenance, cost is lower, has application value widely.

Embodiment
Referring to shown in Fig. 4, Fig. 5, Fig. 6, Fig. 7 and Fig. 8, is stereo appearance figure of the present utility model, three-dimensional exploded view, cut-open view, preferred embodiment figure and the further illustration of implementing, and by knowing and find out in figure, the utility model mainly includes:
One fiber connector 2, its one end has an abutting end 21, on these abutting end 21 outside surfaces and be provided with plural groove 211;
At least one optical fiber 3, one termination is located in this fiber connector 2;
One protective sleeve 4, its one end has a junction 41, and is sheathed on by this connecting portion 41 on the abutting end 21 of fiber connector 2;
The utility model is mainly that the connecting portion 41 that sees through protective sleeve 4 one end is sheathed on the abutting end 21 of fiber connector 2, except in order to protect fiber connector 2 with optical fiber 3 the two part that are connected, more can increase the tightness degree of fiber connector 2 and optical fiber 3 the two combination, and be sheathed on after fiber connector 2 when protective sleeve 4, mainly to see through the plural groove 211 arranging on abutting end 21, increase contact area and friction factor between abutting end 21 and protective sleeve 4, and then improve combination degree closely, protective sleeve 4 can not come off because of pullling easily of external force, moreover, seeing through protective sleeve 4 is the design of convergent kenel, more can this end portion complete envelope optical fiber 3, improve by this stable contiguity of optical fiber and fiber connector, make optical fiber 3 can not rupture or depart from easily fiber connector 2 because of pullling of external force, and the plural groove 211 arranging on seeing through abutting end 21 improves the combination degree closely between abutting end 21 and protective sleeve 4, separately can on the surface of abutting end 21, be coated with an adhesion layer 5, more to improve the combination degree of the two by this adhesion layer 5,
