Carbon fiber wire and method of processing and connecting the carbon fiber wire and metal line joint

Abstract

A carbon fiber wire comprises carbon fiber yarns. A first high temperature resistance protecting layer is arranged on the outer side of the carbon fiber yarns. A second high temperature resistance protecting layer is arranged on the outer side of the first high temperature resistance protecting layer. The wall thickness of the first high temperature resistance protecting layer ranges from 2 mm to 3 mm. The carbon fiber wire with a reasonable structure is simple to operate. The internal carbon fiber yarns are prevented from being damaged during a carbon fiber wire rotary-cut peeling process. The basic design power of a product is unchanged. The power and heat can be easily controlled during later-stage using processes. Furthermore, the carbon fiber yarns and metal line joints are tightly and firmly connected. Reliable performance is achieved. No special joint temperature rise emerges. High-temperature or even ablation phenomena caused by virtual connection can be prevented. The carbon fiber wire is safe and reliable.

Description

Technical field: [0001] The invention relates to a carbon fiber wire and a method for processing and connecting the joint with a metal wire. Background technique: [0002] At present, carbon fiber wire is used as a heating element, and can be used to make any heating products, which is very popular among users. When used, the carbon fiber wire needs to be connected with the metal wire to connect the circuit. In practice, because the first high temperature resistant protective layer of the existing carbon fiber wire is too thin, 99% of the carbon fiber wire is peeled after peeling during a rotary cut. The carbon fiber filaments will be damaged and broken around the filaments. Sometimes the carbon fiber filaments are damaged by more than 5%, and the resistance increases, which greatly changes the basic design power of the product, resulting in the inability to control power and heat during later use. In addition, carbon fiber wires and metal wire joints are usually directly c...
