Insect-proof termite-proof protective long-life branch cable and manufacturing method thereof

Abstract

The invention discloses an insect-proof termite-proof protective long-life branch cable and a manufacturing method thereof. The outer side edge end of a connecting conductor is coated with an insulating protective layer; the edge end of the insulating protective layer is spirally and tightly wound with a metal heat-insulation belt; a wrapping layer is tightly wound on the outer side of the metal heat-insulation belt and located at the joint of a main cable sheath and a branch cable sheath; and the outer side of the wrapping layer is sleeved with a metal protective cover. According to the invention, when the branch cable is manufactured, the outer side of the branch cable can be protected in the mode that the metal protective cover is additionally arranged on the outer side of the joint ofthe branch cable, and a molten polyvinyl chloride material is injected into a filling chamber on the inner side of the metal protective cover in an injection molding manner, so the injected material has high protection performance at the joint of the branch cable after being cured and molded, and the joint of the branch cable has higher pressure-bearing and pressure-resisting capability; and thus,the effect of improving the mechanical strength of the branch cable is achieved.

Description

technical field [0001] The invention relates to the technical field of branch cables, in particular to an insect-proof and long-life branch cable and a manufacturing method thereof. Background technique [0002] The branch cable is the main and branch cable model, specification, cross-section, length and branch position required by the factory according to the requirements of the cable user. A series of special production equipment in the factory is produced on the assembly line with a branch cable. It is a new technology product that comes, and the branch cable and the pre-branch cable refer to the branch cable leading to the cable trunk; [0003] In the actual application process of the branch cable, due to the lack of protective and fixed components at the connection between the main cable and the branch cable, on the one hand, the stability of the connection between them cannot be guaranteed; on the other hand, due to the lack of protection at the connection between them...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides an anti-insect long-life branch cable and its manufacturing method, which can effectively solve the problem of lack of protective and fixed components at the connection between the main cable and the branch cable during the actual application of the branch cable proposed in the background technology. On the one hand, the stability of the connection between them cannot be guaranteed. On the other hand, due to the lack of protection of the connection between them, it is easy for external insects and small insects to enter the connection between them, which will cause damage to the connection between them. , so that the service life of the branch cables in the actual application process is reduced, and in the prior art, because the connection between them is protected by a covering material, after covering the material, the shape of the branch cable connection The specifications cannot be determined, which will cause the shape of the branch cable to be ugly. At the same time, the protection will be formed by the covering material, which will also reduce the overall protection performance of the branch cable.
