Problems solved by technology

[0003] In the prior art, the wire core of the conductive wire is usually made of metal monofilament drawing, which is made of metal filaments after drawing and annealing to microfilaments, which are assembled into bundles and twisted; metal monofilament drawing is usually only It can be drawn to a wire diameter of 0.03mm, and the continuous drawing and thinning process is complicated, the production efficiency and yield are very low, and the cost increases
[0004] Existing multi-core wires are formed by twisting multiple strands. Due to the thick wire diameter, their bending resistance is poor. When bending with a small curvature such as a radius of curvature of 1 mm, the multi-core wires w...

Embodiment 1

[0023] Embodiment 1: a kind of electric wire production process, comprises the following steps:

[0024] 1) Single wire drawing, under the condition of 38 ℃, using a wire drawing machine, through a drawing die, the copper rod is drawn, and the diameter of the drawing is 10um;

[0025] 2) Monofilament annealing, annealing through an annealing furnace, annealing temperature 330 ° C, annealing time 40 minutes, to make metal monofilament;

[0026] 3) Surface treatment, the metal wire is first surface treated to form an isolation coating, the isolation coating is a mixed coating of silicon nitride and silicon powder, and the mass ratio of silicon nitride and silicon powder is 3:4;

[0027] 4) Stranding, which is formed by twisting at least one metal monofilament and at least one non-conductive metal monofilament, and uses a compactor to compact the wire;

[0028] 5) Coating, covering the outer side of the wire with an insulating layer. The thickness of the insulating layer is 1.5m...

Embodiment 2

[0029] Example 2: The rest is the same as Example 1, the difference is that in step 1), the temperature of monofilament drawing is 28 degrees Celsius, and the diameter of the drawn wire is 5um. In step 2), the annealing temperature is 280°C, and the annealing time is For 30 minutes, step 5), the thickness of the insulating layer is 1.5mm.

Embodiment 3

[0030] Example 3: The rest is the same as Example 1, the difference is that in step 1), the temperature of monofilament drawing is 48 degrees Celsius, the diameter of the drawn wire is 20um, in step 2), the annealing temperature is 380°C, and the annealing time is For 50 minutes, step 5), the thickness of the insulating layer is 2mm.

[0031] After the above process steps, the wire samples are taken out, and the tested performance is as follows:

[0032] The flexible electric wire produced by the present invention can be bent without deformation with a small curvature, and the folding resistance is improved. The conductive fabric woven by the flexible electric wire can be directly washed by hand; It will not scratch the insulating layer; due to the small diameter of the metal fiber, it has good softness and spinnability.

[0033] The flexible wires can be used as conductive leads according to the needs of the circuit and arranged together with other fiber yarns by weaving or ...

Description

technical field [0001] The invention relates to the field of wire manufacturing, in particular to a wire production process. Background technique [0002] The softness of the wire and cable, that is, the bendability, depends on the elasticity of the conductive thread and the diameter of a single metal wire, as well as the pitch of the helical winding. Since the core of the conductive thread needs to use a specific metal wire, the elasticity of the conductive thread is not variable. However, the variable range of the pitch is limited relative to the diameter of the wire and cable. So the biggest variable is the diameter of the individual wires, the smaller the diameter, the smaller the bendable radius and the better the bendability. [0003] In the prior art, the wire core of the conductive wire is usually made of metal monofilament drawing, which is made of metal filaments after drawing and annealing to microfilaments, which are assembled into bundles and twisted; metal mo...
