Abstract
The utility model relates to a three-layered tinned stranded insulation wire, which comprises a regular hexagonal copper conductor constituted by seven copper wires, a tin plating layer plated on the outer surface of the copper wires, a polyetheretherketone insulating layer wrapped outside the tin plating layer, and a polyamide resin layer wrapped outside the polyetheretherketone insulating layer. Compared with the prior art, the three-layered tinned stranded insulation wire has grade-F (155 DEG) heat resistance and the wire body is more wear-resistant and easy to wind and process. Novel transformers or high-frequency coils using the three-layered tinned stranded insulation wire have considerable advantages over the prior art in size and weight reduction and are high in safe reliability and stability.
Description
Technical field
The utility model relates to a kind of insulated winding wire, especially relates to a kind of zinc-plated strand insulation high line of three-decker, is applied to safety standard and meets UL1950, the transformer of IEC60950 and high frequency winding coil.
Background technology
Be used at present the three-layer insulated stranded winding wire on transformer or the high frequency coil, by the multiply copper conductor, two layers polyester insulation and the insulation of outer polyamide form, and this class insulated wire thermal endurance class is E level (130 ℃), the B level (℃).Along with electronics, telecommunication, the fast development of power-supply device, the temperature resistant grade of E level (130 ℃) and B level (130 ℃) can not satisfy the requirement of safety, reliable, stability, the higher three-layer insulated winding wires of electronic market active demand thermal endurance class.
The utility model content
The purpose of this utility model is exactly the zinc-plated strand insulation high line that the higher three-decker that is used for transformer or high frequency coil of a kind of thermal endurance class is provided for the defective that overcomes above-mentioned prior art existence.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of zinc-plated strand insulation high line of three-decker, this twisted wire comprises:
Copper conductor: consist of a regular hexagon structure by 7 copper wires;
Tin coating: plating is located at the outer surface of copper wire;
Polyether-ether-ketone insulating barrier: the outside that is packaged in tin coating;
Polyamide layer: the outside that is packaged in the polyether-ether-ketone insulating barrier.
Described copper wire is that diameter is electrician's annealed copper wire of 1.17mm.
Described polyether-ether-ketone insulating barrier is provided with two-layer, is packaged in successively the outside of tin coating, consists of the insulating mechanism of twisted wire.
Compared with prior art, the utility model is owing to the composite insulation layer and one deck resin structure layer that have adopted double-layer structure, and the tin coating that cooperates inside to arrange, so that thermal endurance class reaches F level (155 ℃), gained line body is more wear-resisting, is easy to coiling, is easy to processing.Adopt novel transformer of the present utility model or high frequency coil aspect volume-diminished and weight minimizing, to have outside the suitable advantage with prior art, its security reliability, stability height.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment
A kind of zinc-plated twisted wire three-layer insulated winding wires for transformer or high frequency coil, its structure as shown in Figure 1, comprise copper conductor 1, tin coating 2, two-layer polyether-ether-ketone insulating barrier 3, polyamide layer 4, electrician's annealed copper wire that copper conductor 1 is 1.17mm by 7 diameters consists of a regular hexagon structure, tin coating 2 is plated on the outside of annealed copper wire, two-layer polyether-ether-ketone layer 3 extrudes successively in tin coating 2 outsides, and polyamide layer 4 extrudes in the outside of two-layer polyether-ether-ketone layer 3.
Carry out again strandedly after using electrician's annealed copper wire of Ф 1.17mm to be coated with tin through annealing after the drawing-down, two-layer polyether-ether-ketone insulating barrier 3 and polyamide insulating barrier 4 are extruded in the outside of tinned copper conductor twisted wire by 3 plastic extruding machines of 30 types.
The performance that is used for the tinned copper conductor twisted wire three-layer insulated winding wires of transformer or high frequency coil is:
1, temperature resistant grade F level (155 ℃);
2, its anti-interference of tinned copper conductor and high frequency are all good than copper conductor;
3, tinned wird is better than fine copper wire non-oxidizability;
4, resistance to wear and surface smoothness are good, and voltage-resistent characteristic is good, and puncture voltage obtains the evaluation of heavy insulation (test voltage=3000Vrms, 1min) greater than 15kV;
5, need not just can directly weld by peeling outer layer 420 ℃≤3S of solderability;
6, chemically-resistant solvent, anti-impregnating varnish performance is good;
7, extrusion molding excellent processing performance.
But 8, the three-layer insulated twisted wire high frequency coil of gained volume-diminished, high frequency performance is better.
GPX-F (JX) three-layer insulated winding wires and common GPX-B (IX) the three-layer insulated winding wires Performance Ratio that are used for transformer or high frequency coil are more as shown in table 1.
