Embodiment 1

[0033] Embodiment one: the present invention discloses a kind of coaxial cable production technique (see attached figure 1 , 2 , 3, 4, 5), including the following steps:

[0034] 1) copper wire drawing process: drawing copper wire as conductor 1;

[0035] 2) Foam insulation injection molding and cooling process: injecting and covering the outer surface of the conductor 1 with a foam insulation material to form a foam insulation layer 2, and cooling the surface covered with the foam insulation material;

[0036] 3) Copper tape wrapping and welding process: wrap the copper tape to the foam insulation surface, and weld it into a seamless outer conductor layer 3;

[0037] 4) Spray coating and curing process: spray heat-insulating and corrosion-resistant coating 4 on the outer conductor layer 3, and dry and cure;

[0038] 5) Sleeve fiber sleeve process: weave fiber net 8 and wrap it on the coaxial cable to form fiber sleeve 5;

[0039] 6) Melting and cooling process: melting th...

Embodiment 2

[0046]Embodiment two: the fiber web 8 in the step 5) and step 6) is woven by the first fiber 51 and the second fiber 52, and the metal wire is braided in the first fiber 51, and the second fiber 52 The melting temperature of the second fiber 52 is lower than the melting temperature of the first fiber 51; the melting temperature of the second fiber 52 is 150° C. to form the skeleton 7 structure. In the melting and cooling process of step 6), the fiber sheath 5 is melted and cooled by blowing air at 5°C. Air purging at 5°C-10°C cools faster and is convenient for cooling with shorter contact time on the assembly line. In the actual production process, the length of the purge equipment and the setting of the nozzle are adjusted according to the flow rate of the assembly line.

[0047] The fiber sheath 5 is melted at a temperature of 150°C. The melting time is 15 minutes. With an external heating temperature of 100°C-150°C and a melting time of 5min-15min, the heating temperature...

Abstract

The invention discloses a coaxial cable production technology. The technology comprises the following steps: 1, copper wire fine-drawing operation; 2, foaming insulation injection molding and cooling operation; 3, copper belt wrapping and welding operation; 4, film spraying and solidification operation; 5, fiber sleeve joining operation; 6, fusion cooling operation; 7, insulation layer injection molding and cooling operation; and 8, blow-dry operation, wherein a fiber web in the fifth step and the sixth step is formed by braiding first fibers and second fibers, metal wires are braided into the first fibers, and the fusing temperature of the second fibers is smaller than the fusing temperature of the first fibers; and the second fibers are fused to form a skeleton structure, and the fusing temperature of the second fibers is 100 to 150 DEG C. According to the invention, a fiber sleeve formed by braiding the first fibers and the second fibers is used, the structure is simple, the damping effect is good, the bending and stretching performance is quite excellent, by use of fiber materials, the metal wires can be easily braided, an overall cable has a better economic effect, and through adoption of the fiber materials, improvement of various chemical properties of a coaxial cable protective layer is facilitated.

Description

technical field [0001] The invention relates to the field of cable production, in particular to a coaxial cable production process. Background technique [0002] Coaxial cables can be divided into two basic types, baseband coaxial cables and broadband coaxial cables. At present, the baseband is a commonly used cable, and its shielding wire is a mesh made of copper, with a characteristic impedance of 50 (such as RG-8, RG-58, etc.); the shielding layer of the cable commonly used in broadband coaxial cables is usually made of aluminum. Stamped, the characteristic impedance is 75 (such as RG-59, etc.). [0003] Coaxial cables can be divided into thick coaxial cables and thin coaxial cables according to their diameters. The thick cable is suitable for a relatively large local network. It has a long standard distance and high reliability. Since the cable does not need to be cut during installation, the network access position of the computer can be flexibly adjusted according to...
