Abstract
The invention relates to a method for manufacturing a three-layer insulating winding wire. The method comprises the following steps of: performing annealing after fine-drawing a phi 3mm copper bar by a drawbench, orderly extruding and wrapping two layers of polyester insulation layers on the exterior of a copper conductor through a triple-head extruding machine, extruding and wrapping a polyamide resin insulation layer on the exterior of the two layers of polyester insulation layers, and then coating a layer of self-binding paint insulation layer on the exterior of the polyamide resin insulation layer to obtain the three-layer insulating winding wire. Compared with the prior art, the method of the invention is simple. By coating a self-binding paint on the exterior of three layers of insulation layers, the product obtained by the method has a high voltage resistance property and an excellent high-frequency property of a formed frameless coil and is applicable to the development tendency of the current information industry.
Description
Technical field
The invention belongs to the self-binding enamel wire technical field, it is applied to the exoskeletal winding coil of high frequency that safety standard meets UL1950, IEC60950, is specifically related to a kind of manufacture method of three-layer insulated winding wires.
Background technology
The present enamelled wire on exoskeletal coil, by copper conductor, Polyurethane insulating barrier outward again lacquer cover the tack lacquer and form, its insulated electro is forced down, high frequency performance is not good enough, can not satisfy and adapt to the high pressure resistant requirement with high frequency of electronic building brick.
Summary of the invention
Purpose of the present invention is exactly for a kind of manufacture method that replaces the three-layer insulated winding wires of self-binding enamel wire product is provided.
Purpose of the present invention can be achieved through the following technical solutions:
A kind of manufacture method of three-layer insulated winding wires, it is characterized in that, this method adopts Φ 3mm copper bar to anneal after the wire drawing machine drawing-down, successively the two layers polyester insulating barrier is extruded in the copper conductor outside by three plastic extruding machines then, the polyamide insulating barrier is extruded in outside this two layers polyester insulating barrier again, at last tack varnished insulation layer is coated in polyamide insulating barrier outside, obtains three-layer insulated winding wires.
Compared with prior art, the inventive method is simple, and the product that adopts this method to obtain coats with lacquer owing to apply tack outside three-layer insulated layer, makes the exoskeletal coil proof voltage height of shaping, and high frequency performance is good, is applicable to the current information industry development.
The advantage of product of the present invention is alternative traditional self-binding enamel wire product, makes electronic building brick proof voltage height, and high frequency performance is good.
Embodiment
The invention will be further described below in conjunction with specific embodiment.
A kind of manufacture method of three-layer insulated winding wires, this method adopts Φ 3mm copper bar to anneal after the wire drawing machine drawing-down, by three plastic extruding machines of 30 types the two layers polyester insulating barrier is extruded in the copper conductor outside then, the polyamide insulating barrier is extruded in outside this two layers polyester insulating barrier again, at last tack varnished insulation layer is coated in polyamide insulating barrier outside, obtains three-layer insulated winding wires.
The performance of the three-layer insulated winding wires that is used for the exoskeletal coil of high frequency that the present invention obtains is:
(1) production specification scope: 0.20～1.00mm;
(2) temperature resistant grade B level (130 ℃), outer self-adhesive layer thermal endurance class are B level (130 ℃) and F level (155 ℃);
(3) voltage-resistent characteristic is good, and puncture voltage obtains heavy insulation (test voltage=3000Vrms, evaluation 1min) greater than 15kV;
(4) can directly weld 420 ℃≤3S of solderability;
(5) can pure soluble self-adhering, average cohesive force 〉=0.886N (0.40mm);
(6) high frequency performance is good.
GPX-B (ZZ) the tack three-layer insulated winding wires and the common heat resistant alcohol-soluble UESUW/F self-binding enamel wire performance that are used for the exoskeletal coil of high frequency are more as shown in table 1.
