Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, right
The present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, not
For limiting the present invention.
The present invention improves the connecting method of splicing cables resistance to tension, comprises the following steps:
S1, respectively insert a metallic supports 3 in the end of two optical cables to be continued；
S2, that steel pipe 5 is set in wherein optical cable is outside standby, and in the pyrocondensation of the outside sheathed inner wall belt glue of steel pipe 5
Pipe 8 is standby；
Optical fiber in two optical cables that S3, welding are to be continued；
S4, the end seal of interior two optical cables being inserted with metallic supports 3 is fixed in steel pipe 5 two ends；
S5, with pressing mold crimp steel pipe 5 two ends；
S6, by heat-shrink tube 8, steel pipe 5 is carried out pyrocondensation encapsulation.
In one embodiment of the present of invention, as shown in Figure 2 (a) shows, metallic supports 3 is hollow pipe.As shown in Fig. 2 (b), can
Arrange limited step in one end of metallic supports 3, the other end of metallic supports 3 is set to taper, it is simple to insert in optical cable.Peace
During dress, limited step is stuck in the port of optical cable so that assembling is easier to, and after crimping, not only the squeezed pressure of optical cable is big, and optical cable is with golden
Belong to support member 3 to be difficult to be pulled.
In another embodiment of the present invention, as shown in Figure 2 (c), also one can be provided with in one end of metallic supports 3
Limited step and at least one anticreep step, also can arrange the boss of taper at its other end, and after crimping, optical cable is stuck in metal
At support member 3 anticreep step, it is possible to increase pull the resistance of optical cable.
In one preferred embodiment of the present invention, can be first long according to weld length, metallic supports 3 length and steel pipe 5
The rigging position of degree, at optical cable 1 one end labelling steel pipe 5 placement location, the crimping position of labelling pressing mold 4 on steel pipe 5.
Inner sleeve 6 and the optical fiber 7 of optical cable 1 one end are reserved certain length, and makes optical cable inner sleeve 6 through metallic supports
3, then metallic supports 3 is inserted optical cable 1 internal, make metallic supports 3 limited step against optical cable port, as shown in Figure 1.
The heat-shrink tube 8 of steel pipe 5 and inner wall belt glue is standby through optical cable 1.
Another root optical cable continued by needs is ready to as stated above, two optical fiber of welding.
Above-mentioned optical cable 1 and metallic supports 3 periphery are coated waterproof gasket cement, then steel pipe 5 is inserted in optical cable 1, steel pipe 5
The alignment marked position of optical cable 1, one end, rotates and makes glue be fully contacted.
Another root optical cable gluing in aforementioned manners is directed at steel pipe 5 other end.
Pressing mold 4 is directed at marked position on steel pipe 5, crimps steel pipe 5 two ends with instruments such as hydraulic tongses, as shown in Figure 1.
The heat-shrink tube 8 of inner wall belt glue is put steel pipe 5, with instrument pyrocondensations such as heat guns, after having assembled as shown in Figure 4.
In the embodiment of the present invention, pressing mold 4 is the hexagon of two sideband double wedges, as shown in Figure 3.After pressing mold 4 crimps steel pipe 5
Effect is as shown in Figure 4.Because cable interior has metallic supports 3(as shown in Figure 2) and outside steel pipe 5, interior after pressing mold 4 crimping deformation
Outer extruding optical cable forms the biggest crimp force, reaches to improve the resistance to tension of splicing cables.
For applying the hexagon pressing mold 4 of two sideband double wedges, after steel pipe 5 is crimped, more there is gmatjpdumamics；For application steel pipe
The metallic supports 3 of form, after crimping, in optical cable, epipolar restriction is bigger；According to the metallic supports 3 of limited location stepped form,
Assembling is easier to, and after crimping, not only the squeezed pressure of optical cable is big, and optical cable and support member are difficult to pull；According to limited location step and
Individual or the metallic supports 3 of multiple anticreep stepped form, after crimping, optical cable is stuck in the recessed place of support member, increases and pulls optical cable
Resistance.
By the junction structure of the optical cable that said method completes, as it is shown in figure 5, include:
Two metallic supports 3, are plugged on the end of to be continued two piece optical cable 1 respectively；
Steel pipe 5, is crimped on the optical cable 1 after two weldings outside, and the end seal of two optical cables 1 is at the two ends of this steel pipe 5
In；
Heat-shrink tube 8, it is outside that pyrocondensation is encapsulated in steel pipe 5.
To sum up, the present invention can improve splicing cables resistance to tension, simple to operate, and with low cost, size is little, good looking appearance.
Can be widely used in the fields such as Fibre Optical Sensor, fiber-optic transfer, fiber optic communication.
It should be appreciated that for those of ordinary skills, can be improved according to the above description or be converted,
And all these modifications and variations all should belong to the protection domain of claims of the present invention.
