Description
Technical field
The utility model belongs to cable for digital communication technical field, particularly a kind of high-strength tensile house data cable.
Background technology
Along with the development of informationized society, digital communication obtains very large development, because data cable can be subject to larger pulling force when laying, conference of exerting oneself causes the conductor drawing-down of digital communication line inside, affect the transmission performance of data cable, indoor easily mouse bites broken, has higher requirement, therefore need the data cable of high, the resistance to damaged by rats of a kind of tensile strength of design badly to the physical property of data cable and mouse bite preventing.
Utility model content
The purpose of this utility model is high for designing a kind of tensile strength described in solution background technology, the problem of the data cable of resistance to damaged by rats, a kind of high-strength tensile house data cable is provided, it is characterized in that, extrude insulating barrier 2 outside conductor 1 and form wire, every 2 wire strandings become one to line group, the core of the skeleton 3 of corner star-shaped cross-section is cylindrical cavity, center strengthening core 4 to be placed in the cylindrical cavity of skeleton 3 and filling disks cylindrical cavity along the longitudinal direction of skeleton 3, 4 are placed in the space between the adjacent angular of skeleton 3 to line group respectively, space between the adjacent angular of skeleton 3 is full of and factice for filling 6 by nylon yarn 5, use belting layer 7 wrapped again, form the cable core of circular cross section, belting layer 7 outer coated inner restrictive coating 8 and the external sheath layer 9 successively of cable core,
Described conductor 1 is copper cash or tinned wird;
The material of described insulating barrier 2 is polyethylene;
Described to line group, its twisting pitch is not more than 50mm;
The material of described skeleton 3 is nylon;
Described center strengthening core 4 is stranded multi-end polyester filament;
Described ointment 6 to block water factice for filling for hot type;
Described belting layer 7 is the polyester belt of two-layer 0.05mm ~ 0.07mm;
The material of described inner restrictive coating 8 is nylon;
The material of described external sheath layer 9 is flame-retardant low-smoke halogen-free polyolefin.
The beneficial effects of the utility model are, adopt the center strengthening core that skeleton is coated, nylon yarn is filled and nylon sheath, improves the tensile strength of data cable; To filled nylon silk and ointment between line group and skeleton in cable core, skeleton by each pair of line group separately, improves the transmission performance of cable; Adopt low-smoke halide-free fireproof composite polyolefine material as jacket material, external sheath layer intensity is high, effectively prevents damaged by rats, decreases the impact by environment.
