Problems solved by technology

[0003] However, the double-layer glass filaments of these structures all adopt a small pitch, that is, a winding angle of 1-2°. When the coil is wound, the bending and adhesion performance of the winding wire cannot meet the requirements, and the bending surface of the winding coil is easy to produce during use. The insulation layer is cracked, causing its coil to be damaged and shorten its service life

Embodiment Construction

[0012] The preferred embodiments of the present invention are given below in conjunction with the accompanying drawings to describe the technical solution of the present invention in detail.

[0013] like figure 1 As shown, in the prior art, a wrapping angle of 1-2° is adopted, so that when the coil is wound, especially the glass filament at the bending part will reduce the adhesion performance due to bending cracks. like figure 2 As shown, the present invention adopts a mesh glass fiber layer whose winding pitch n is more than 5 millimeters and less than 6 millimeters, and the winding angle a is greater than 10° and less than 30°, so that the phenomenon of bending and cracking of the winding wire when winding the coil can be avoided. And ensure that the glass wire is close to the copper flat wire, especially can improve the adhesion of the bending part of the copper flat wire.

[0014] like image 3 Shown, the production technology of double glass fiber clad copper flat w...

Abstract

The invention discloses a double-glass-fiber covered enamelled copper flat wire, which is formed of wrapping double-layer glass fiber on a copper flat wire and coating a layer of bonding paint on the surface and among all layers, and the double-layer glass fiber adopts reticular glass fiber layers with the wrapping pitch greater than 5mm and smaller than 6mm and the wrapping angle greater than 10 degrees and smaller than 30 degrees. The invention also discloses a production process of the double-glass-fiber covered enamelled copper flat wire. The double-glass-fiber covered enamelled copper flat wire has the advantages that the indexes of performance such as the bending performance, the sticking performance and the like are improved, the use requirements can be met, and the service life is prolonged.

Description

technical field [0001] The invention relates to a flat copper-clad double-glass wire and a production process thereof, in particular to a copper-clad double-glass flat wire suitable for dry motors and electric appliances and a production process thereof. Background technique [0002] At present, the winding wires used in motors and electrical products generally use copper flat wires or mica tape copper-clad flat wires to wrap double-layer glass filaments, and a layer of bonding varnish is applied between each layer and on the surface to solve the problem of insulation. [0003] However, the double-layer glass filaments of these structures all adopt a small pitch, that is, a winding angle of 1-2°. When the coil is wound, the bending and adhesion performance of the winding wire cannot meet the requirements, and the bending surface of the winding coil is easy to produce during use. The insulation layer is cracked, causing its coil to be damaged and shorten its service life. C...
