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 h...

specific Embodiment approach

[0016] The specific implementation, non-limiting examples are as follows:

Embodiment

[0017] Example: see figure 1 , the cable conductor of the present embodiment includes, the anti-stretch layer 1 in the inner layer, which is made of multiple strands of high-strength spun yarn fibers twisted and twisted, and the twisted and twisted directions are the same, and its tensile strength The strength is 2 to 5 times that of steel wire, dozens of times that of copper wire, and its elongation is less than 4%, while the elongation of copper wire is about 15 to 25%. Strong bending resistance, suitable for wire drawing of various mobile cable conductors.

[0018] The conductor layer 2 is wound on the anti-drawing layer 1 with thin tinned annealed copper wire or thin annealed copper wire in layers. The winding direction of each layer is opposite from the inside to the outside, and the winding direction of the outermost layer is left. This structural form The pitch is very small, and the length of the conductor monofilament is 1.3 to 1.5 times the original length. When the...

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...
