Abstract
The present utility model discloses a wire and cable formed by arranging a sheath over a plurality of polytetrafluoroethylene powder pushing insulated wires. The wire and cable is provided with a plurality of polytetrafluoroethylene powder pushing insulated wires which are twisted together, each polytetrafluoroethylene powder pushing insulated wire is provided with a wire core, a polytetrafluoroethylene powder pushing insulated layer is wrapped outside the wire core, a metal shielding layer is wrapped outside the polytetrafluoroethylene powder pushing insulated wire, and the sheath is sleeved outside the metal shielding layer. In the wire and cable, the insulated wires are twisted, and the sheath is sleeved outside, thus damages of the metal shielding layers and the insulated layers caused by long-time sun scorching and rain drenching can be effectively prevented, and the wire and cable can be prevented from being gnawed and destroyed by bugs and ants.
Description
Technical field:
The utility model relates to field of cables, relates in particular to the electric wire that many polytetrafluoroethylene powders are pushed insulation tape sheath.
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 the electric wire that many polytetrafluoroethylene powders are pushed insulation tape sheath; Solve high temperature resistant fluoropolymer insulated wire cable in the past; 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:
Many polytetrafluoroethylene powders are pushed the electric wire of insulation tape sheath: have the some polytetrafluoroethylene powders that twist together and push insulated wire; Said polytetrafluoroethylene powder is pushed insulated wire and is had a core, and core is wrapped with the polytetrafluoroethylene powder and pushes insulating barrier; The polytetrafluoroethylene powder is pushed insulated wire 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 outside dimension of metal screen layer; 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 twisting together some insulated wires, 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:
Many polytetrafluoroethylene powders are pushed the electric wire of insulation tape sheath: have the some polytetrafluoroethylene powders that twist together and push insulated wire, said polytetrafluoroethylene powder is pushed insulated wire and is had a core 1, and core 1 is wrapped with the polytetrafluoroethylene powder and pushes insulating barrier 2; The polytetrafluoroethylene powder is pushed insulated wire and is wrapped with metal screen layer 3, is set with sheath 4 outside the metal screen layer 3, and core 1 is silver-plated copper core or nickel-clad copper core; Structure is for only son and heir's monofilament or the multifilament bundle is stranded forms, and the polytetrafluoroethylene powder is pushed insulating barrier 2, is 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 metal screen layer 3 again through high temperature sintering; 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, and sheath 4 forms for the several layers polytetrafluoroethylene film wraps up layer by layer; Or the polytetrafluoroethylene powder made the tubulose molding mass through preforming tool; Put into barrel,, select the different moulds of pushing according to the outside dimension of metal screen layer; Molding mass in barrel pushing extruded be wrapped on the metal screen layer, process through high temperature sintering again.
The foregoing description is merely the preferred implementation of the utility model, and in addition, the utility model can also have other implementations.Need to prove that under the prerequisite that does not break away from the utility model design, any conspicuous improvement and modification all should fall within the protection range of the utility model.
