Abstract
The utility model discloses a cable possessing multiple stranded polytetrafluoroethylene film wrapped insulating wires and shielding wires. The cable is provided with a plurality of polytetrafluoroethylene film wrapped insulating wires and a plurality of polytetrafluoroethylene film wrapped insulating shielding wires, and the insulating wires and the insulating shielding wires are stranded together. Each polytetrafluoroethylene film wrapped insulating wire is provided with a wire core, and the outside of the wire core is coated with a polytetrafluoroethylene film wrapped insulating layer. Each polytetrafluoroethylene film wrapped insulating shielding wire is also provided with the wire core, and the outside of the wire core is coated with the polytetrafluoroethylene film wrapped insulating layer. The outside of the polytetrafluoroethylene film wrapped insulating layer is also coated with a secondary metal shielding layer. The outside of the stranded wires is coated with a primary metal shielding layer, and the outside of the primary metal shielding layer is sleeved with a sheath. Through stranding a plurality of insulating wires and a plurality of shielding wires, and arranging the sheath on the outside, the damages of a metal shielding layer and an insulating layer caused by the long-term outdoor exposure can be effectively avoided, and the damages of the cable caused by insect and ant bites can also be prevented.
Description
Technical field:
The utility model relates to field of cables, relates in particular to a kind of many polytetrafluoroethylene film lapped insulation lines and the shielding conductor cable of strand mutually.
Background technology:
Polytetrafluoroethylene film lapped insulation electric wire belongs to a kind of of high temperature resistant fluoropolymer insulated wire cable, is the cable kind of using under space flight and the particular surroundings, and its characteristic is high temperature resistant, corrosion-resistant, and physics and chemical stability are strong; Polytetrafluoroethylene film lapped insulation electric wire is not in the past installed protector outside it, exposes to the sun and rain for a long time to cause metal screen layer and insulating barrier to damage, and also receives the destructions that bite such as worm ant easily.Therefore imagination provides a kind of equipment to solve this problem.
The utility model content:
The purpose of the utility model just provides the cable of a kind of many polytetrafluoroethylene film lapped insulation lines and the mutual strand of shielding conductor; Solve polytetrafluoroethylene film lapped insulation electric wire in the past; Outside it screening arrangement is not installed, so phase mutual interference between the loop and the more serious problem of external disturbance.
The technical scheme that the utility model adopts is:
Many polytetrafluoroethylene film lapped insulation lines and shielding conductor be the cable of strand mutually: have some polytetrafluoroethylene film lapped insulation lines and some polytetrafluoroethylene film lapped insulation shielding conductors twist together each other; Said polytetrafluoroethylene film lapped insulation line has a core; Core is wrapped with polytetrafluoroethylene film lapped insulation layer; Said polytetrafluoroethylene film lapped insulation shielding conductor also has a core; Core also is enclosed with polytetrafluoroethylene film lapped insulation layer outward, and polytetrafluoroethylene film lapped insulation layer also is enclosed with branch metal screen outward; The line that twists together is wrapped with total metal screen layer, and total metal screen layer is set with sheath outward.
Said core is silver-plated copper core or naked copper core, and structure is for only son and heir's monofilament or the multifilament bundle is stranded forms.
Said polytetrafluoroethylene film lapped insulation layer is the size according to the core cross section, and polytetrafluoroethylene film is cut into the band shape of different in width, and spiral is wrapped on conductor wire core, and film is put up rate 1/2 or 2/3, through the high temperature sintering operation with the insulating barrier bonding firmly.
Said minute metal screen and total metal screen layer; The cylinder-shaped coat of forming by the metal tape of overlapping winding of individual layer, bilayer or multilayer or braiding, thin plain conductor; Its material can be steel, copper, aluminium or lead, also adopts bimetallic or multiple metal composite to process sometimes.
Said sheath is that the several layers polytetrafluoroethylene film wraps up layer by layer and forming; Or according to the outside dimension of metal screen layer; Select different extrusion dies, granular exhaustive fluorinated ethylene propylene or resin extruded being wrapped on the metal screen layer of Meltability polytetrafluorethyletubular are processed.
Compared with prior art, the beneficial effect of the utility model is:
The utility model is through twisting together some insulated wires and shielding conductor, and outside it structure of suit protective jacket, can effectively avoid exposes to the sun and rain for a long time can cause metal screen layer and insulating barrier to damage, and also can prevent that cable from receiving the destructions that bite such as worm ant.
Description of drawings:
Accompanying drawing 1 is the utility model structural representation.
Embodiment:
Below in conjunction with accompanying drawing, the utility model is done further explain through embodiment:
A kind of many polytetrafluoroethylene film lapped insulation lines and shielding conductor be the cable of strand mutually: have some polytetrafluoroethylene film lapped insulation lines and some polytetrafluoroethylene film lapped insulation shielding conductors twist together each other; Said polytetrafluoroethylene film lapped insulation line has a core 1; Core 1 is wrapped with polytetrafluoroethylene film lapped insulation layer 2; Said polytetrafluoroethylene film lapped insulation shielding conductor also has a core 1; The core 1 outer polytetrafluoroethylene film lapped insulation layer 2 that also is enclosed with, the polytetrafluoroethylene film lapped insulation layer 2 outer branch metal screen 3 that also is enclosed with; The line that twists together is wrapped with total metal screen layer 4, is set with sheath 5 outside total metal screen layer 4, and core 1 is silver-plated copper core or naked copper core; Structure is for only son and heir's monofilament or the multifilament bundle is stranded forms, and polytetrafluoroethylene film lapped insulation layer 2 is the sizes according to the core cross section; Polytetrafluoroethylene film is cut into the band shape of different in width; Spiral is wrapped on conductor wire core, and film is put up rate 1/2 or 2/3, through the high temperature sintering operation with the insulating barrier bonding firmly; Divide metal screen 3 and total metal screen layer 4; By the cylinder-shaped coat that the metal tape of overlapping winding of individual layer, bilayer or multilayer or braiding, thin plain conductor are formed, its material can be steel, copper, aluminium or lead, also adopts bimetallic or multiple metal composite to process sometimes; Sheath 5 forms for the several layers polytetrafluoroethylene film wraps up layer by layer; Or, select different extrusion dies according to the outside dimension of metal screen layer, granular exhaustive fluorinated ethylene propylene or resin extruded being wrapped on the metal screen layer of Meltability polytetrafluorethyletubular are processed.
