Electromagnetic Trailing Cable

Abstract

The invention relates to an electromagnetic towing cable. The electromagnetic towing cable includes an electric wire core and a protective ring; the electric wire core is composed of wires tightly twisted together; Closed wire loops are arranged, the ring surface of each said wire loop extends radially along the protection ring, the axis of the wire loop is oblique to the axis of the protection ring and the inclination direction of each wire loop is consistent; Diodes are also installed on the ring; a thermal expansion ring is fixed on the inner ring surface of the protection ring, and micro-protrusions are densely distributed on the outer ring surface of the protection ring; the cable structure is simple, easy to store, and can effectively protect the cable , while facilitating the handling of cables.

Description

technical field [0001] The present invention relates to a cable, in particular, a trailing cable. Background technique [0002] Towing cables are mostly used in occasions where equipment units need to move back and forth, such as robotic arms, workbenches, etc.; it places the cables in the cable drag chain to prevent the cables from being entangled, worn, pulled off and scattered during the towing process. This kind of cable has high flexibility; the traditional drag chain cable has a structure similar to a crawler, so it is also called a tank chain cable or a drag chain cable; however, the traditional drag cable is too bulky and must occupy a large space when it is coiled and stored; the crawler track The structure of the cable drag chain is complex, which requires a lot of labor costs and wastes a lot of time during production; in addition, there are many inconveniences during use: since the crawler can only be bent in one plane direction, it needs to be installed before u...

[0002] Drag cables are mostly used in occasions where equipment units need to move back and forth, such as mechanical arms, workbenches, etc.; it places the cables in the cable drag chain to prevent the cables from being entangled, worn, pulled off and scattered during the dragging process. This kind of cable has high flexibility; the traditional drag chain cable structure is similar to the track, so it is also called tank chain cable or drag chain cable; but the traditional drag cable is too large and must occupy a large space when it is coiled and stored; the track Shaped cable chains have a complex structure, which consumes a lot of labor costs and wastes a lot of time during production; in addition, there are many inconveniences in the use process: since the track can only be bent in one plane direction, it needs to be bent before use. It is placed in a suitable position to facilitate the translation of the cable; at the same time, it is necessary to rotate the reel and then remove the cable when it is untied from the cable reel, and the operation is more cumbersome; There is still much room for improvement
