Extruding-resistant and bending-resistant complex cable

Abstract

The invention discloses an extruding-resistant and bending-resistant complex cable. The extruding-resistant and bending-resistant complex cable comprises a cable core, a second wrapping layer, a metal woven protection layer and a jacket layer, wherein an elastic support frame is arranged in the cable core, and consists of an inner barrel, an outer barrel and a plurality of support plates which are distributed along the radial direction of the cable core; one end of each support plate is positioned in the inner barrel, and the other end of each support plate passes through the inner barrel and the outer barrel; an arc-shaped protection part of each support plate positioned at the tail end of the outer side of the outer barrel is pressed against the inner wall of the second wrapping layer; a plurality of leads are longitudinally arranged between any two adjacent support plates, are positioned on the outer side of the outer barrel, and stick close to the support plates on both sides, the outer wall of the outer barrel and the inner walls of the arc-shaped protection parts; a plurality of groups of signal lines are longitudinally arranged between any two adjacent support plates, and are positioned between the inner barrel and the outer barrel; the core layer is coated with the wrapping layer, the metal woven protection layer and the jacket layer in sequence. The extruding-resistant and bending-resistant complex cable is resistant to extruding and bending, and is simple and stable in structure.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to an extrusion-resistant and bending-resistant composite cable. Background technique [0002] In metallurgy, electric power, petrochemical and other working environments that have special requirements for cables such as mobile anti-corrosion, cables are more likely to be squeezed and stretched by the outside after installation, especially in the process of anti-extrusion, the wires in the cable core are easily deformed or even The core is easy to break, and the smooth transmission of power and communication cannot be guaranteed, causing huge economic losses. Therefore, how to manufacture an integrated cable that is resistant to extrusion and bending, and has a simple and stable structure has become a technical problem to be solved urgently by those skilled in the art. Contents of the invention [0003] In order to solve the technical problems existing in the background technology...
