Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cables, in particular to a flexible cable which is convenient for bending and laying. Background Art
[0002] Cable is a device for transmitting electric energy or signals, usually composed of several or several groups of wires. There are many types of cables, including power cables, control cables, compensation cables, shielded cables, high temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mining cables, aluminum alloy cables, etc. They are all composed of single or multiple wires and insulation layers, used to connect circuits, electrical appliances, etc.
[0003] When laying cables, they often encounter corners and obstacles blocking the way. At this time, the cables need to be bent to fit the curve to facilitate the continued laying work. However, when ordinary cables are bent, the film layer on their surface will be deformed due to the tensile force of the bending, which will cause the surface layer of the cable at the bend to become thinner. During long-term burial underground, the cable surface may be damaged, thus affecting its use. In order to solve the above problems, while facilitating the bending of the cable, the overall structure of the cable is strengthened to avoid damage that affects its use. For this reason, we propose a flexible cable that is easy to bend and lay. Utility Model Content
