Problems solved by technology

[0002] At present, most low-voltage air circuit breakers adopt a single breakpoint structure in structure, which is compact in layout and easy to meet the requirements of miniaturization. The moving contacts are often connected to the outlet bar through flexible connections; It is made of superimposed multi-layer copper skin. Although it is easy to process, when the soft moving contact made of superimposed copper skin moves, the inner layer of copper skin is compressed due to the bending of the soft connection, and the outer layer of copper skin is stretched. Not soft enough, which brings resistance to the movement of the moving contact, which greatly affects the performance of the low-voltage air circuit breaker

Abstract

The invention discloses a super-thin oxidation resisting copper braided wire which is knitted by a purple copper wire with a diameter of 0.04-0.07mm; and the cross section of the super-thin oxidation resisting copper braided wire is rectangle. The invention also discloses a method for manufacturing the super-thin oxidation resisting copper braided wire. After annealed at a high temperature, the super-thin oxidation resisting copper braided wire is soft, bright, oxidation resisting, and not easy to turn black; the copper braided wire produced by using the method for manufacturing the super-thin oxidation resisting copper braided wire has good quality; and the manufacturing process is energy-saving and environment-friendly.

Description

technical field [0001] The invention relates to a copper braided wire, in particular to an annealed soft, bright and oxidation-resistant ultra-fine anti-oxidation copper braided wire, and also provides a manufacturing method of the ultra-fine anti-oxidation copper braided wire. Background technique [0002] At present, most low-voltage air circuit breakers adopt a single breakpoint structure in structure, which is compact in layout and easy to meet the requirements of miniaturization. The moving contacts are often connected to the outlet bar through flexible connections; It is made of superimposed multi-layer copper skin. Although it is easy to process, when the soft moving contact made of superimposed copper skin moves, the inner layer of copper skin is compressed due to the bending of the soft connection, and the outer layer of copper skin is stretched. It is not soft enough, which brings resistance to the movement of the moving contact, which greatly affects the performan...
