Connecting method for carbon fibers and metal wire connector

Abstract

The invention discloses a connecting method for carbon fibers and a metal wire connector, and relates to connection for carbon fibers and metal. The connecting method comprises the following steps of (1) slurry coating: heating conductive slurry to 50-150 DEG C and diluting, and coating heads of the carbon fibers and the head of a metal wire with the heated and diluted conductive slurry, and meanwhile, immersing a copper pipe into the heated and diluted conductive slurry; (2) curing: putting the carbon fibers, the metal wire and the copper plate after being coated with slurry into air to be naturally cured for 5-20min; (3) connecting: enabling the cured heads of the carbon fibers and the metal wire to be arranged in the cured copper pipe in a sleeving manner; (5) crimping: putting the carbon fibers and the metal wire, which are arranged in the copper pipe in a sleeving manner, on a terminal crimping machine to be impacted and crimped; and (5) injection molding: coating the crimped copper pipe with a thermal shrinkage sleeve, and putting the overall connector on an injection molding machine to be subjected to overall injection molding. The connecting method is simple to operate, capable of realizing tight and firm connection, and safe and reliable in performance.

Description

technical field [0001] The invention relates to a connection between carbon fiber filaments and metals, in particular to a connection method between carbon fiber filaments and metal wire joints. Background technique [0002] As a heating element, carbon fiber filaments can be used to make heating and heating products, especially ground heating. Carbon fiber filament is a kind of black body material. The heating of carbon fiber filament is to convert electric energy into heat energy under the condition of electrification. The electrothermal conversion efficiency is high and saves electric energy. At present, carbon fiber filament is a very thin bundle, and carbon fiber filament needs to be connected with metal wires. To connect the circuit, in practice, the metal wire joints of carbon fiber wires are usually connected by metal terminals or copper paste, etc., and the connection performance is poor. Many can not be connected, the connection is not good, the contact resistance...

Carbon fiber filament is a kind of black body material. The heating of carbon fiber filament is to convert electric energy into heat energy under the condition of electrification. The electrothermal conversion efficiency is high and saves electric energy. At present, carbon fiber filament is a very thin bundle, and carbon fiber filament needs to be connected with metal wires. To connect the circuit, in practice, the metal wire joints of carbon fiber wires are usually connected by metal terminals or copper paste, etc., and the connection performance is poor. Many can not be connected, the connection is not good, the contact resistance increases correspondingly and heats up, when the temperature of the joint is too high and the oxidation is fast, it is also prone to ablation, which not only affects the performance, but also has certain safety hazards
