Abstract
The utility model discloses a polytetrafluoroethylene powder pushing insulated wire cable possessing a sheath. The polytetrafluoroethylene powder pushing insulated wire cable includes a wire core. The outside of the wire core is coated with a polytetrafluoroethylene power pushing insulating layer. The outside of the polytetrafluoroethylene power pushing insulating layer is coated with a metal shielding layer. The wire core is a silver-plated copper wire core or a nickel-plated copper wire core. The structure of the wire core is that the wire core is formed by stranding a single filament bundle or multiple filament bundles. The polytetrafluoroethylene power pushing insulating layer is prepared by the following steps: the polytetrafluoroethylene power is formed into a tubular material via a pre-forming die, and then the tubular material is put into a material barrel, and next the tubular material is pushed out of the material barrel to coat a conductive wire core via a pushing die, and finally the polytetrafluoroethylene power pushing insulating layer is prepared by high temperature sintering. The metal shielding layer is a cylindrical outer sleeve which is formed by metal belts and thin metal leads which are superposingly wound or woven into a single-layer, dual-layer, or multi-layer structure. The sheath is formed by multiple layers of polytetrafluoroethylene films. Through arranging the sheath on the outside of the insulating layer, the damage of the metal shielding layer and the insulating layer caused by the long-term outdoor exposure can be effectively prevented, and the cable can be prevented from being bitten by insects.
Description
Technical field:
The utility model relates to field of cables, relates in particular to a kind of polytetrafluoroethylene powder with sheath and pushes insulated wire cable.
Background technology:
It is belong to high temperature resistant fluoropolymer insulated wire cable a kind of that the polytetrafluoroethylene powder is pushed 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 powder is in the past pushed insulated wire cable, outside it protector is not installed, 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 a kind of polytetrafluoroethylene powder with sheath and pushes insulated wire cable; The polytetrafluoroethylene powder that solves is in the past pushed insulated wire cable; Its outer protector of not installing; Expose to the sun and rain for a long time and can cause metal screen layer and insulating barrier to damage, also receive the problem of the destructions that bite such as worm ant easily.
The technical scheme that the utility model adopts is:
The polytetrafluoroethylene powder of band sheath is pushed insulated wire cable, and comprise core: core is wrapped with the polytetrafluoroethylene powder and pushes insulating barrier, and the polytetrafluoroethylene powder is pushed insulating barrier and is wrapped with metal screen layer, and metal screen layer is set with sheath outward.
Said core is silver-plated copper core or nickel-clad copper core, and structure is for only son and heir's monofilament or the multifilament bundle is stranded forms.
Said polytetrafluoroethylene powder is pushed insulating barrier; Be that the polytetrafluoroethylene powder is made the tubulose molding mass through preforming tool; Put into barrel,, select the different moulds of pushing according to the size of cross-sectional area of conductor with the insulation external diameter; Molding mass in barrel pushing extruded be wrapped on the conductor wire core, process through high temperature sintering again.
Said metal screen layer, 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.
Said sheath is that the several layers polytetrafluoroethylene film wraps up layer by layer and forming; Or the polytetrafluoroethylene powder made the tubulose molding mass through preforming tool; Put into barrel,, select the different moulds of pushing according to the size of cross-sectional area of conductor with the insulation external diameter; Molding mass in barrel pushing extruded be wrapped on the metal screen layer, process through high temperature sintering again.
Compared with prior art, the beneficial effect of the utility model is:
The utility model is through installing the structure of protective jacket outside insulating barrier, 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.
