220-grade enameled copper round wire for automobile starting motor

Abstract

The invention discloses a 220-grade enameled copper round wire for an automobile starting motor. The enameled copper round wire comprises a silica gel strip; a flat aluminum strip is spirally wound onthe silica gel strip; a tooth groove which extends along the spiral direction of the flat aluminum strip is formed in the outer side surface of the flat aluminum strip; a toothed belt which extends along the spiral direction of the flat aluminum strip is arranged on the inner side surface of the flat aluminum strip; a copper layer meshed with the tooth groove is arranged on the spiral surface ofthe flat aluminum strip; a plurality of paint-placing grooves are formed in the outer surface of the copper layer; the outer surface of the copper layer is coated with high-temperature-resistant insulating paint; the thickness of the copper layer ranges from 0.15mm to 0.25mm; the silica gel strip is a silica gel strip with the heat-resistant temperature of 250 DEG C or above; the paint-placing grooves are spirally wound on the outer peripheral surface of the copper layer; and a plurality of paint-placing grooves are uniformly distributed in the outer surface of the copper layer. The enameled copper round wire has the advantages that the copper consumption is small, and the cost of manufacturing the automobile starting motor is low, the coil winding is easy, and the stability of the insulation performance is high.

Description

technical field [0001] The invention belongs to the field of 220-grade enameled wires for automobile starter motors, in particular to a 220-grade enameled round copper wire for automobile starter motors. Background technique [0002] Existing 220-grade enameled wires for automobile starter motors are composed of conductive copper wires of the inner core and insulating layers of the outer layer. With the rapid development of the automobile industry, the amount of 220-grade enameled wire used in automobile starter motors has increased rapidly, and the total amount of copper used in automobile starter motors has accounted for a considerable part of the total copper consumption in society. This not only makes scarce copper Resources are tighter, and a large amount of high-priced copper is used to make the cost of the car's starter motor high. The existing 220-grade enameled wires for automobile starter motors use solid copper wires, the material is relatively hard, and the coil...

Problems solved by technology

With the rapid development of the automobile industry, the amount of 220-grade enameled wire used in automobile starter motors has increased rapidly, and the total amount of copper used in automobile starter motors has accounted for a considerable part of the total copper consumption in society. This not only makes scarce copper Resources are tighter, and a large amount of high-priced copper makes the cost of the car's starter motor high

The existing 220-grade enameled wires for automobile starter motors use solid copper wires, the material is relatively hard, and coil winding is difficult

In addition, when the enameled wire is painted, the paint on the insulating layer has a tendency to flow downward under the action of gravity, and the produced enameled wire is prone to uneven paint film thickness, and the stability of the insulation performance is poor.

[0003] Therefore, the existing 220-grade enameled wire for automobile starter motors has the disadvantages of large amount of copper and high cost for making automobile starter motors, and the winding of the coil is difficult, and the stability of insulation performance is poor.
