Embodiment Construction

[0008] As shown in the figure, after the main cable 1 and the branch cable 4 are connected by the connecting body 2, the product of the present invention adopts a heat-fused material suitable for the original cable to wrap around the wrapping tape to form a heat-fused wrapping layer 3. Hot-melt splicing around the cladding layer 3 and then wrapping high-temperature-resistant plastic tape, soft copper tape, etc. in sequence to form a sheath layer. Heat is used to achieve fusion bonding of the materials surrounding the cladding layer 3 by heat fusion, so that the branch cables 4 and the main cables 1 are closely combined.

[0009] The invention discloses an idea of ​​a new type of branch cable, which can also be used in branch cables of various other materials and different forms. The same function and effect can be achieved without substantial changes to the above-mentioned method of the invention , all belong to the protection scope of the present invention.

Abstract

The invention discloses a branch cable comprising a main cable and a branch cable which are connected through a connector; the connection part of the main cable and the branch cable is provided with a hot melt taped covering; and a jacket layer is arranged outside the hot melt taped covering. The hot melt taped covering is formed by winding a tape made of a hot melt material. A large expensive injection molding unit and die in the prior art are not needed, and therefore, the production cost is reduced, and meanwhile, the safety and the reliability are improved.

Description

[0001] technical field [0002] The invention relates to the field of power cables, in particular to a branch cable. Background technique [0003] Branch cables are mostly used in high-rise buildings as main and trunk cables for power supply and distribution. It can be divided into three parts in structure: main cable, branch cable and branch connector. The branch cables are generally prefabricated by the factory and manufactured according to the corresponding size according to the surveying and mapping requirements. The conductors of the main cable and the branch cables are compressed and connected by copper or copper alloy, and a complete insulation treatment is performed. However, this method leads to very high requirements for surveying and mapping. Once a certain data is wrong, it may cause cumulative errors. When the data is wrong, it is generally only found during on-site installation, and it cannot be changed after production. Once there is a change, production must...
