Abstract
The present invention relates to a heat-resistant wire coated with silicone rubber which is used for the heating coil, the wire being mainly suitable to the coil winding and the leading line of microwave oven. It includes from the inner to outer portion a core 1 made of nickel plated copper wires, an insulating layer 2 made of silicone rubber, a weaving layer 3 made of Dacron and an outer heat-resistant coating 4. The weaving layer of the invention has high strength, good wear-resistance, long operating life and good firmness of color attachment.
Description
Technical field:
The present invention relates to a kind of electric wire.Particularly relate to a kind of heater coil silicon rubber heat-resisting electric wire.Mainly be applicable to the coil windings and the lead wire of micro-wave oven transformer.
Background technology:
At present, generally be used for the coil windings of micro-wave oven transformer and the electric wire of lead wire, tinned copper wire core, silicone rubber insulation layer, fiberglass braided layer and outer heat-resisting red insulating varnish coating are arranged from the inside to the outside successively.It mainly has the following disadvantages:
1, fiberglass braided layer intensity is too low, and it is easy to wear to add the man-hour surface, the damage silicone rubber insulation layer;
2, the glass fibre tiny dust of fray causes that easily operator's skin itches even cause allergic;
3, the at high temperature easy oxidation blackout of tinned copper wire core is quickened silicon rubber and is worn out, terminal connections place frangibility, and electric wire is short useful life;
4, the outer insulation paint immersion coating of electric wire easily fades, and the surface colour firmness is poor.
Summary of the invention:
The objective of the invention is to overcome above-mentioned deficiency, a kind of braid intensity height is provided, resistance to wear is good, to human zero damage, long service life, heater coil silicon rubber heat-resisting electric wire that the firm coloration degree is good.
The object of the present invention is achieved like this: a kind of heater coil silicon rubber heat-resisting electric wire has nickel-clad copper silk thread core, silicone rubber insulation layer, polyester fiber braid and outer refractory coating from the inside to the outside successively.
Polyester fiber braid of the present invention adopts the coloring polyester fiber braid, and its colorant directly adds in the polyester fiber raw material.
Its major advantage is:
1, polyester fiber braid intensity height is wear-resisting, can more effectively protect silicone rubber insulation layer;
2, the polyester fiber braid does not have any unwholesome dust generation, and environmental-protection function is obvious;
3, nickel-clad copper silk thread core intensity is higher than tinned copper wire, and the terminal connections place is frangibility not, can oxidation under 200 ℃, prolonged the useful life of electric wire.
4, colorant directly adds in the polyester fiber braid raw material, can not produce and fade, and the firm coloration degree is good.
Description of drawings:
Fig. 1 is a cross-sectional structure schematic diagram of the present invention.
Embodiment:
As Fig. 1, the present invention is a kind of heater coil silicon rubber heat-resisting electric wire.Be used for the coil windings of micro-wave oven transformer and the electric wire of lead wire.It is made up of nickel-clad copper silk thread core 1, silicone rubber insulation layer 2, coloring polyester fiber braid 3 and outer refractory coating 4 from the inside to the outside successively.The polyester fiber braid adopts light resistance: 7-8 level, heatproof:＞300 ℃ of nondiscolourings, the red polyester fiber of anti-migration below 5 grades.Its colorant directly adds in the polyester fiber raw material.
