Abstract
The utility model provides an insulation conducting wire and a coil made of same. The insulation conducting wire comprises a conducting wire and an insulation paper, wherein insulation paint is painted on the insulation paper, the insulation paper wraps outside the conducting wire, with the surface, on which the insulation paint is painted, of the insulation paper faces outward. The insulation paint on the insulation paper is in block structures which are distributed uniformly, the blocks with consistent intervals are distributed on the surface of the insulation paper. The coil is made of the insulation conducting wire through winding. The insulation paint on the insulation paper are bonded together after being heated through applying electricity on two ends of the conducting wire, and the insulation paint is solidified and moulded when the temperature is reduced to a normal level after the power is turned off, so that the surfaces of the conducting wires are bonded together, and a reliable insulation coil is formed.

Background technology
The insulation of winding wire is the basic demand to transformer, be widely used at present the technique that is heating and curing in forming materials, coating spraying, circuit substrate manufacturing also through being usually used in the insulation of voltage device and motor coil, its principle is that the bonding coating with electrical insulation capability mutually bonds together under specified temp, solidify to form the adhesive linkage with some strength in the time of normal temperature.
In motor, transformer coil formation curing process, generally adopt gluing to fix, machinery is fixing or be directly dried and carried out forming and hardening by dipping lacquer, people seek simple and easy reliable method in this field always and reach the object of expection.The patent of invention that for example publication number is CN101847505A, its method is that insulating varnish is uniformly coated on to NOMEX paper and glass cloth surface, then NOMEX paper and the glass cloth with insulating varnish are wound on wire, reaches the object of insulation; And the utility model that publication number is CN 202034096 U discloses a kind of ultra thin special paint packed round copper line, mainly formed by superminiature circular copper wire, on copper cash, scribble polyurethane paint and make insulating barrier, be coated with again polyester-imide paint outward at insulating barrier and make the self-adhesion paint in semi-cured state, in use, enamelled wire is wound into various shapes, in the energising heating of winding two ends, in several seconds, self-adhesion paint completes the conversion to bonding sizing by semi-cured state.
State of the art also exists improves part.
Summary of the invention
In order to make up the deficiencies in the prior art part, the purpose of this utility model is to provide that a kind of processing method is simple, reliable insulated conductor and the coil with its making insulate.
In order to realize foregoing invention object, the technical solution adopted in the utility model is as follows: a kind of insulated conductor, comprise wire and insulating paper, and it is characterized in that, on described insulating paper, be coated with insulating varnish, the one side of insulating paper coating insulating varnish is wrapped in wire external layer outwardly.
Further, the insulating varnish on described insulating paper is equally distributed block structure, and between each, spacing is unanimously distributed in insulating paper surface.
Further, described wire and be coated with the insulating paper that is wound around one or more layers not tape insulation paint between the insulating paper of insulating varnish.
Further, described conductor cross-section is circle, ellipse or rectangle.
The coil of making according to above-mentioned insulated conductor, is characterized in that, described coil is formed by described insulated conductor coiling, and after the energising heating of wire two ends, the insulating varnish on insulating paper is heated and is mutually bonded together; The temperature that stops switching on is down to normal temperature insulating varnish curing molding, and the insulating paper of conductive line surfaces is bonded together, and forms the coil of reliable insulation.
The utility model, in order to realize the be heating and curing object of insulation of motor, transformer coil, is made insulated conductor by being wound around one deck in conductive line surfaces with the insulating paper of insulating varnish; Use again such wire coiling motor and transformer coil, after coil winding moulding, guiding line two ends pass into electric current, realize coil temperature rise by the autonomous heating of conductor resistance, under specified temp and keep a period of time, mutually bond together with the insulating paper of block insulation paint subsequently.When temperature is down to after normal temperature, insulating varnish curing molding, the insulating paper of conductive line surfaces bonds together, and realizes the integral solidifying of coil.In heating process, can adjust coil dimension by the mode of knocking, make coil meet design size requirement; Be down to after normal temperature, insulating varnish solidifies, and realizes the curing molding of whole coil, improves mechanical performance and the impact resistance of coil.
