Embodiment 1

[0028] The pretreatment is mainly to realize the acquisition of carbon fiber wire and metal wire. Generally, the carbon fiber heating wire and metal wire are multi-layer structures. Vinyl insulation, silicone insulation and carbon fiber filaments. The structure of the metal wire is pvc anti-corrosion layer, polyethylene insulating layer and tinned copper wire from outside to inside.

[0029] In this embodiment, the pretreatment is mainly to peel the outer multilayer structure of the carbon fiber heating wire and the metal wire, that is, to peel the PVC anti-corrosion layer, the polyethylene insulating layer and the silicone insulating layer of the carbon fiber heating wire and the metal wire. , peel off the multi-layer structure of the outer layer of carbon fiber filaments, and do pretreatment for subsequent connection realization.

[0030] Specifically, use peeling equipment to peel off the PVC anti-corrosion layer, the polyethylene insulating layer and the silicone insulati...

Embodiment 2

[0055] The difference from Example 1 is that the carbon fiber hot and cold wire joint forming process provided in Example 2 does not require flux attachment. That is, the method for obtaining the tinned copper wire in the method provided in this embodiment is different from that in Embodiment 1.

[0056] The processing technology of the tinned copper wire provided by this embodiment includes the following specific steps:

[0057] (1) Carry out cathodic protection to the copper wire after pickling treatment and introduce it into the tin pool, make the copper wire pass through the tin-plated eye mold after being fully immersed, and export the tin-plated copper wire vertically upward;

[0058] (2) The tinned copper wire that was exported was sequentially cooled at a cooling rate of 7°C / min to about 15°C, and then further cooled and pulled at a cooling rate of 15°C / min to obtain a finished tinned copper wire.

[0059] In this embodiment, the first composite filaments are also obt...

Embodiment 3

[0065] (1) Carry out cathodic protection to the copper wire after pickling treatment and introduce it into the tin pool, make the copper wire pass through the tin-plated eye mold after being fully immersed, and export the tin-plated copper wire vertically upward;

[0066] (2) Cool the lead-out tinned copper wire to about 15°C at a cooling rate of 10°C / min in turn, then further cool and pull it at a cooling rate of 30°C / min, add guide shaft oil and then take up the wire to obtain a finished tin-plated wire copper wire.

Abstract

The invention relates to a carbon fiber cold and hot wire joint with a hinge process and a hinge forming process thereof, which realizes the connection of carbon fiber wires and metal wires; obtains carbon fiber wires through pretreatment; obtains tinned copper wires; The first composite wire is completely formed; the first composite wire and the metal wire are welded; the welded carbon fiber wire and the metal wire are reinforced to realize the connection and fixation of the carbon fiber wire and the metal wire; The connection between the carbon fiber wire and the metal wire is solved, and the problem that the hot and cold wire cannot be directly formed is solved by welding. The method improves the contact area of ​​the connection and reduces the contact resistance; also improves the butt strength of the cold and hot joints, and avoids the risk of the joints falling off; the method is easy to operate, has high reliability and is low in cost.

Description

technical field [0001] The invention relates to a carbon fiber hot and cold wire joint with a hinge process and a hinge forming process thereof, which realizes the connection between carbon fiber wires and metal wires. Background technique [0002] In the heating method using the carbon fiber heating wire as the heating source, it is necessary to connect the carbon fiber heating wire and the metal wire. Because carbon fiber is a non-metallic material, it cannot be directly welded and other technological connections like metal materials. However, the reliable connection between the carbon fiber heating wire and the metal wire can greatly improve the quality and service life of the product, and its connection technology is a topic worthy of further exploration in this industry. [0003] In the current prior art, the connection between the carbon fiber heating wire and the metal wire generally adopts the connection method of crimping, bonding with conductive glue, or a combina...
