High tensile and bend resistant movables cable conductor

Abstract

The invention discloses a high tensile and bend resistant movable cable conductor. The cable conductor comprises a tensile wire layer positioned in an inner layer and formed by adopting a plurality of strands of aramid silk fiber strands and multiple strands and a conductor layer formed by respectively enwinding a plurality of homocentric tinning annealed copper wires or annealed bare copper wires on the tensile wire layer. The enwinding directions of each layer of tinning annealed copper wires or annealed base copper wires are opposite from inside to outside. The invention can be taken as the conductor of various movable cables; the cables can freely move, have smaller bending radius, and can freely move along with a movable device, and the conductor service life thereof can be improved to tens of times.

Description

Technical field: [0001] The present invention relates to cable conductors, and more particularly to a high tensile, bending resistant moving cable conductor. Background technique: [0002] With the continuous development of my country's economic construction, the consumption of various mobile power equipment is increasing, and the consumption of mobile cables is increasing day by day. [0003] At present, there are many places where mobile cables are used in my country, such as ports, docks, mines, metallurgy and other industries. There are many mobile devices that require a large number of mobile cables. Mobile devices need to move back and forth during work, and mobile devices and remote power control The cabinets are connected by long cables. When the mobile device works to the front, it needs to move back and forth. During this process, the cables will form severe bending and dragging in the shape of "8", "N" or "S". . The inner coil core of the bent cable is subjected t...

AI Technical Summary

Problems solved by technology

The inner coil core of the bent cable is subjected to great pressure and the outer coil core is subject to great tension, and when the mobile device is walking, a longitudinal tension is formed on the cable, which makes the cable conductor easy to break, so it is required The mobile device system should have protection against cable bending, but it is difficult for mobile devices to do so. The structure of the original conductor is twisted, re-twisted, and then twisted concentrically, and it does not have the ability to resist bending. Therefore, it must be Considering that the cable conductor itself has certain bending resistance and tensile strength, that is, the cable can still maintain normal operation when it is bent to a certain radius at a certain temperature for thousands or even tens of thousands of times and subjected to a huge pulling force. The conductor does not break, but so far there is no conductor for a mobile device special cable with excellent bending resistance and tensile resistance.
