Redundant heavy-current power supply cable assembly and assembly method thereof

Abstract

The invention relates to a redundant heavy-current power supply cable assembly and an assembly method thereof. In the redundant heavy-current power supply cable assembly, a mold shrinkage sleeve is sleeved at the crotch of a cable conductor trunk wire harness converged by a plurality of cable conductor branching basic wiring harnesses; and one end of each cable conductor branching basic wiring harness is provided with an A terminal, an identifier is sleeved at the A terminal, and the other end of each cable conductor branching basic wiring harness is provided with a B terminal. The invention has the advantages that: due to the adoption of a bifurcate and branching design of a cable, the cable assembly has a flexible structure and is easy to assemble; the terminals with corresponding specifications can be subjected to compression joint according to the wiring harnesses with different sectional areas, so that the cable assembly meets assembly modes of different space sizes; the cable assembly can be recycled and also can be assembled in a butt joint mode; an outer sheath of the integral cable is made of an oil-resistant, wear-resistant and high temperature-resistant material, so that the integral cable is sealed and protected completely to ensure the safe and reliable use of the cable effectively; the cable assembly is easy to wire and can be wired according to different wiring spaces on site, so that the effective space occupied by a transmission system is small; and compared with copper sheets with the same sectional areas, the cable assembly has the advantage that: the overcurrent is increased.

Description

Technical field: [0001] The invention relates to a redundant high-current power supply cable assembly and an assembly method thereof which provide reliable channels for high-current transmission. It is used for high-load transmission between various high-power equipment, especially some equipment with narrow space and strict wiring requirements, such as the interior of the aircraft cabin, for easy installation and maintenance. Background technique: [0002] In the process of system design and production, it is necessary to modularize the system to facilitate its production and installation, shorten its research and development cycle, and reduce maintenance costs. The subsystems need to be connected through detachable cable assemblies to form a reliable electrical connection. For high-power equipment, high-power power transmission is required between the power supply and equipment or between equipment and equipment. In order to improve the efficiency of power transmission, i...

Problems solved by technology

Its shortcoming is that the cable assembly has a fixed structure and can only be straddled between subsystems or equipment, which increases the difficulty of equipment appearance design; Long and difficult to transport and install

At the same time, if there is a large AC current passing through, because of the skin effect of the copper conductor, the effective conductive cross-sectional area will be reduced, thereby increasing the resistance, increasing the heat on the cable, and seriously damaging the outer insulation of the cable, making the cable The metal core is exposed to the air, which increases the leakage current of the cable and seriously affects the safety of maintenance personnel
