Description
Technical field
The a plurality of conductors that the present invention relates to a kind of will have a resistance heat or shielding electromagnetic wave are arranged on the bedding special-purpose non-magnetic electric-heat wire on the same axle, relate in particular to the thinner bedding special-purpose non-magnetic electric-heat wire that is coated with at least one conductor in a kind of described a plurality of conductors as the enamel layer of heat-resisting and insulating material.
Background technology
Be used as the existing non magnetic heating wire of the heater of beddings such as electric heating floor, electric blanket or electric mattress, roughly comprise: by the heart yearn of polyester silk thread (thread) or glass fiber formation, spiral surrounding is arranged on the heater coil on the described heart yearn, for playing the internal insulator that insulating effect is coated on described heart yearn periphery, on the outer peripheral face of described internal insulator, form with lead or cross hatch setting and with the shielding sheath layer of ground ground connection, and be coated on outer insulator on the described shielding sheath layer.In this structure, each end points of described heater coil and shielding sheath layer interconnects and forms the electricity series connection, and its each front end links to each other with the positive and negative terminal of power supply respectively and becomes power input terminal.
The existing bedding special-purpose non-magnetic electric-heat wire of said structure, to coil and the energising of shielding sheath layer the time, the resistance heat that produces by electric heater coil generates heat, especially, work as adstante febre, described shielding sheath layer will shield the electromagnetic wave that heater coil produces, and therefore can generate heat under the situation that does not outwards discharge unwanted electromagnetic wave.
But described existing bedding special-purpose non-magnetic electric-heat wire is because internal insulator is thicker, so thick and bending and stretching property is poor.
That is to say, because described existing bedding special-purpose non-magnetic electric-heat wire is at adstante febre, it is softening and its insulation effect straight line is descended that the high thermal conductance of heater coil causes internal insulator, and institute thinks that the short circuit that prevents heater coil and shield the sheath layer has to thicken the thickness of internal insulator.Therefore, the diameter of existing bedding special-purpose non-magnetic electric-heat wire is at least more than 6mm, and is relatively thicker, thereby when being used for electric mattress, causing the electric mattress air spots and the user is not felt well.And be difficult to thin bedding such as electric blanket, woollen blanket, floor because it is thick and bending and stretching property is relatively poor.
Moreover, the insulator of existing bedding special-purpose non-magnetic electric-heat wire is high price materials such as polyflon or glass fibre owing to what adopt, so also there is the high problem of cost.
In addition, though the existing high problem of bedding special-purpose non-magnetic electric-heat wire cost, can by adopting the synthetic resin material to solve, still as the internal insulator material, because the thickness of internal insulator is also thicker than glass fibre, so that the problem of thickness just becomes is more serious.
In another embodiment of prior art, it is on the lead of central shaft glass fibre to be set that a kind of non magnetic heating wire is arranged, and coats the insulated synthetic resin body thereon, thereby prevents the short circuit problem between the lead.But described heating wire fails to solve the problem of thickness equally.And, owing between the glass fibre tissue, have moisture and air layer, thus be difficult to the insulated synthetic resin body is coated thereon, thus there is the problem that productivity ratio is low and production cost is high.
Summary of the invention
The objective of the invention is to provides a kind of bedding special-purpose non-magnetic electric-heat wire for solving described the deficiencies in the prior art, can there be the hidden danger that is short-circuited between its heating conductor and shielded conductor, and owing to it carefully can be used for thin bedding, and the productivity ratio height, cost is low.
Bedding special-purpose non-magnetic electric-heat wire of the present invention comprises: first conductor that is arranged on middle position, the internal insulator that described first conductor of ring bag is provided with, around described internal insulator setting and its terminal second conductor that is connected with the end of described first conductor, ring wraps described internal insulator setting and described second conductor is played the outer insulator of insulating effect, this bedding special-purpose non-magnetic electric-heat wire is characterised in that, described first, at least one conductor in second conductor is the heating conductor of heat of having a resistance after the energized, and described first, be coated with the insulation enamel layer on the outer peripheral face of at least one conductor in second conductor.
In described structure, the enamel layer of heater coil is preferably high temperature hardening polyamide material.
Described second conductor can also can be netted grill-shaped conductor for the linear conductor of the described internal insulator setting of spiral surrounding.
In addition, described first, second conductor respectively can be by the time the have a resistance heating conductor of heat and constitute for the less shielded conductor of resistance that shields the electromagnetic wave ground connection that described heating conductor produces of energising; In addition, two kinds of conductors also can all be made of the hot heating conductor that has a resistance.
Except that described structure, bedding special-purpose non-magnetic electric-heat wire of the present invention can also optionally comprise insulating coating or conduction overlay film.Wherein, insulating coating is arranged on the outer peripheral face of described outer insulator, thereby described shielded conductor is played insulating effect with around described outer insulator setting and the ground connection shielded conductor with the electric field that shields described first, second conductor and produce; The conduction overlay film then encircles the periphery of the described outer insulator of bag, and from absorbing electric charge on every side and it is guided to described shielded conductor, and make by conductive material.
The non magnetic heating wire of bedding class of the present invention of described structure, when described first and second conductor was connected power supply, the resistance heat that relies on first conductor or second conductor to produce generated heat.At this moment, because of offsetting by another conductor screen or by the opposing magnetic field that another conductor produces respectively in electric field and magnetic field that each conductor produces, so can generate heat not discharging under the harmful electromagnetic situation.
According to bedding special-purpose non-magnetic electric-heat wire of the present invention, being coated with the enamel layer of the respond well high temperature hardening polyamide material of thermal endurance height, high-temperature insulation at least one conductor in described first, second heating conductor, therefore is the insulation thickness that is provided with of two insulation between the conductor less than 1/2 of the insulation thickness of existing bedding special-purpose non-magnetic electric-heat wire.With diameter is that existing bedding special-purpose non-magnetic electric-heat wire more than the 6mm is compared, the diameter of non magnetic heating wire of the present invention has only below the 3mm, to have the problem that allows the user not feel well when bedding special-purpose non-magnetic electric-heat wire is used for electric mattress etc. now so can solve, and can be used for thin bedding such as electric blanket, woollen blanket, floor owing to bending and stretching property is higher.Moreover, and need not in order to improve insulation effect on insulator, to use such as insulating material at high price such as polyflon, glass fibre, so the productivity ratio height, production cost is low.
