Embodiment 1

[0028] The pretreatment is mainly to obtain carbon fiber wires and metal wires. Generally, carbon fiber heating wires and metal wires have a multi-layer structure. In this embodiment, the structure of carbon fiber heating wires is PVC anti-corrosion layer, poly Vinyl insulation, silicone insulation and carbon fiber filaments. The structure of the metal wire is a pvc anti-corrosion layer, a polyethylene insulation layer and a tinned copper wire from the outside to the inside.

[0029] In this embodiment, the pretreatment is mainly to peel off the outer multilayer structure of the carbon fiber heating wire and the metal wire, that is, to peel off the pvc anticorrosion layer, polyethylene insulation layer and silica gel insulation layer of the carbon fiber heating wire and 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...

Embodiment 2

[0055] The difference from embodiment 1 is that embodiment 2 provides a carbon fiber cold and hot wire joint forming process without the need to attach flux. That is to say, the method provided in this embodiment is different from that in Embodiment 1 in obtaining the tinned copper wire.

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

[0057] (1) Carry out cathodic protection to the copper wire after the pickling treatment and lead it into the tin pool, after fully immersing, make the copper wire pass through the tinned eye mold, and lead out the tinned copper wire vertically upward;

[0058] (2) The lead-out tinned copper wires were sequentially cooled by about 15°C at a cooling rate of 7°C / min, and then further cooled and pulled at a cooling rate of 15°C / min to obtain finished tinned copper wires.

[0059] In this embodiment, the first composite yarn is obtained by inserting, dividing a...

Embodiment 3

[0065] (1) Carry out cathodic protection to the copper wire after the pickling treatment and lead it into the tin pool, after fully immersing, make the copper wire pass through the tinned eye mold, and lead out the tinned copper wire vertically upward;

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

Abstract

The invention relates to a carbon fiber cold and hot wire joint of a hinging process and a hinging forming process of the carbon fiber cold and hot wire joint. The connection of carbon fibers and metal wires is achieved. Carbon fiber filaments are obtained through pretreatment; a tinned copper wire is obtained; the tinned copper wire is completely wound on the surface of the carbon fiber wire to form a first composite wire; the first composite wire and the metal wire are welded; and the welded carbon fiber wire and the metal wire are reinforced, and the carbon fiber wire and the metal wire are connected and fixed. According to the invention, connection between the carbon fiber wire and the metal wire is achieved through a special winding structure, and the problem that cold and hot wires cannot be directly formed is solved through a welding mode. According to the method, the contact area of the joint is increased, and the contact resistance is reduced; the butt joint strength of the cold and hot joints is improved, and the risk that the joints fall off is avoided; and the method is easy to operate, high in reliability and low in cost.

Description

technical field [0001] The invention relates to a carbon fiber hot and cold wire joint with hinged technology and its hinged forming technology, which realizes the connection of carbon fiber wires and metal wires. Background technique [0002] In the heating method using carbon fiber heating wire as the heating source, it is necessary to connect the carbon fiber heating wire to the metal wire. Since carbon fiber filaments are non-metallic materials, they cannot be connected by direct welding and other processes 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 crimping, bonding with conductive adhesive, or a combination of the two methods. ...
