Description
Technical field
The utility model relates to leading in cable production technical field, particularly a kind of stressed easy curved leading in cable.
Background technology
Domesticly be called leading in cable for the optical cable that enters user, this optical cable arranges reinforcement outward at optical fiber, then protectsCover is coated optical fiber, reinforcement. Although this optical cable is simple in structure, in construction, there is a large amount of problems, causeA large amount of complaints of user, main cause is: the stress-bearing capability of optical cable is too poor, be too simple and easy to cause optical fiber for the protection of optical fiberUnknown cause fracture.
Therefore be necessary existing leading in cable structure to carry out technological innovation further.
Utility model content
The purpose of this utility model is for the defect of prior art and deficiency, provides a kind of simple in structure, and design is closedReason, stressed easy curved leading in cable easy to use.
For achieving the above object, the technical solution adopted in the utility model is:
The stressed easy curved leading in cable of one described in the utility model, comprises optical fiber body, and described optical fiber body is insulatedLayer be wrapped in, described insulating barrier be reinforced layer be wrapped in, described enhancement Layer be modified layer be wrapped in, described modified layer is by restrictive coatingBe wrapped in; In described enhancement Layer, be along the circumferential direction provided with several wires; The cylindrical wall of described modified layer along its lengthBe provided with several bulge loops, between every two adjacent bulge loops, be provided with gap; Described modified layer adopt elastomeric material make andBecome, described enhancement Layer and restrictive coating all adopt pvc material to make.
Further, the quantity of described wire has 12 at least.
Further, the cross section of described bulge loop shape triangular in shape.
Further, the cross-sectional surface area in described gap is greater than the cross-sectional surface area of bulge loop.
Further, the cross section of described bulge loop is equilateral triangle shape.
Adopt after said structure, the utility model beneficial effect is: the stressed easy curved introducing of one described in the utility modelOptical cable, comprises optical fiber body, described optical fiber body be insulated layer be wrapped in, described insulating barrier be reinforced layer be wrapped in, described in addThe strong layer of layer that is modified is wrapped in, and described modified layer is wrapped in by restrictive coating; In described enhancement Layer, be along the circumferential direction provided with someIndividual wire; The cylindrical wall of described modified layer is provided with several bulge loops along its length, between every two adjacent bulge loops, establishesBe equipped with gap; Described modified layer adopts elastomeric material to be made, and described enhancement Layer and restrictive coating all adopt pvc materialMake.
In the time using the utility model, strengthen the resistance to tension of optical fiber by the built-in wire of enhancement Layer, by changingThe bulge loop of property layer strengthens bending resistance, the anti-pressure ability of optical fiber, has greatly improved the stress-bearing capability of whole optical cable, avoids optical cable to go outExisting phenomenon of rupture. The utlity model has simple in structurely, arrange rationally, the advantage such as cost of manufacture is low.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1 to Figure 2, the stressed easy curved leading in cable of one described in the utility model, comprises optical fiber body 1, instituteState optical fiber body 1 and be insulated layer and 2 be wrapped in, described insulating barrier 2 is reinforced layer 3 and is wrapped in, described enhancement Layer 3 layer 4 bag that are modifiedWrapping up in, described modified layer 4 is wrapped in by restrictive coating 6; In described enhancement Layer 3, be along the circumferential direction provided with several wires 5; ThisThe quantity of the wire 5 of utility model has 12 at least.
The cylindrical wall of described modified layer 4 is provided with several bulge loops 4-1 along its length, every two adjacent bulge loop 4-1Between be provided with gap 4-2; Described modified layer 4 adopts elastomeric material to be made, and described enhancement Layer 3 and restrictive coating 6 all adoptPvc material is made.
Further, the cross section of described bulge loop 4-1 shape triangular in shape, the cross section of bulge loop 4-1 of the present utility model is excellentSelect equilateral triangle shape, greatly strengthen bending resistance, the anti-pressure ability of optical fiber.
Further, the cross-sectional surface area of described gap 4-2 is greater than the cross-sectional surface area of bulge loop 4-1; When protectingWhen jacket layer 6 is subject to external force bending or compressive strain, bulge loop 4-1 is just out of shape energy-absorbing, and gap 4-2 can play the cushioning effect of stepping down.
In the time using the utility model, strengthen the resistance to tension of optical fiber by the built-in wire of enhancement Layer, by changingThe bulge loop of property layer strengthens bending resistance, the anti-pressure ability of optical fiber, has greatly improved the stress-bearing capability of whole optical cable, avoids optical cable to go outExisting phenomenon of rupture. In addition, this is simple in structure, reasonable in design, low cost of manufacture.
The above is only preferred embodiments of the present utility model, therefore all according to described in the utility model patent claimThe equivalence done of structure, feature and principle change or modify, be included in the utility model patent claim.
