Embodiment
In order to make object of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
The present invention improves the connecting method of the optical cable tensile ability that continues, and comprises the following steps:
S1, respectively in the end of two optical cables to be continued insert a metallic supports 3;
S2, steel pipe 5 is set in to wherein an optical cable outside is for subsequent use, and for subsequent use at the heat-shrink tube 8 of the outside sheathed inner wall belt glue of steel pipe 5;
Optical fiber in S3, welding two optical cables to be continued;
S4, the end part seal of interior two optical cables that are inserted with metallic supports 3 is fixed in steel pipe 5 two ends;
S5, use pressing mold crimping steel pipe 5 two ends;
S6, by heat-shrink tube 8, steel pipe 5 is carried out to pyrocondensation encapsulation.
In one embodiment of the present of invention, as shown in Figure 2 (a) shows, metallic supports 3 is hollow tubular.As shown in Fig. 2 (b), can limited step be set in one end of metallic supports 3, the other end of metallic supports 3 is made as taper, is convenient to insert in optical cable.When installation, limited step is stuck in the port of optical cable, makes assembling easier, and after crimping, not only the squeezed pressure of optical cable is large, and optical cable and metallic supports 3 is difficult is pulled.
In another embodiment of the present invention, as shown in Figure 2 (c), also can be provided with in one end of metallic supports 3 limited step and at least one anticreep step, the boss of taper also can be set at its other end, after crimping, optical cable is stuck in metallic supports 3 anticreep step places, can increase the resistance that pulls optical cable.
In a preferred embodiment of the present invention, can be first according to the rigging position of weld length, metallic supports 3 length and steel pipe 5 length, at optical cable 1 one end mark steel pipe 5 placement locations, the crimping position of mark pressing mold 4 on steel pipe 5.
By the inner sleeve 6 of optical cable 1 one end and the reserved certain length of optical fiber 7, and make optical cable inner sleeve 6 through metallic supports 3, then metallic supports 3 is inserted to optical cable 1 inside, make metallic supports 3 limited steps near optical cable port, as shown in Figure 1.
The heat-shrink tube of steel pipe 5 and inner wall belt glue 8 is for subsequent use through optical cable 1.
Another root optical cable that needs are continued is ready to as stated above, two optical fiber of welding.
