Anti-interference control cable with buffering inner pipe and position-limited conductors

Abstract

The invention discloses an anti-interference control cable with a buffering inner pipe and position-limited conductors. The control cable includes an inner pipe, an outer pipe and a plurality of conductors. The inner pipe is of a hollow insulating structure. The outer wall of the inner pipe is provided with a plurality of evenly distributed conductor-accommodating grooves. The conductors are evenly distributed in the conductor-accommodating grooves. The outer pipe is sleeved outside the inner pipe and unoccupied parts between the inner pipe and the outer pipe are filled with a buffering material. Each conductor includes a core wire, an insulating layer arranged outside the core wire and an armor layer arranged outside the insulating layer. In the anti-interference control cable, because the inner pipe is of the hollow insulating structure, when the whole cable is bent by an external force, the inner pipe is deformed and plays a buffering role on the external force; when the external force disappears, the inner pipe recovers under the action of the elasticity of the inner pipe itself so that it is ensured that the whole cable is straight and does not affect current or signal transmission quality; and because the position-limiting role played by the conductor accommodating grooves on the core wires, it is prevented that in the prior art, when the cable is bent, distances between the core wires are reduced or increased and thus change of electromagnetic fields is generated, which causes signal or current transmission interferences.

Description

technical field [0001] The invention relates to the field of cable technology, in particular to a position-limiting anti-interference control cable with an inner tube buffer conductor. Background technique [0002] Cables are usually twisted wires, each with inner insulation, twisted around a center, and covered with a highly insulating covering. And each wire is formed by twisting a plurality of core wires. Cables are used in some situations, requiring them to be resistant to bending and stretching. For example, in the field of automatic control, cables often bend due to shaking with parts; and when cables are bent or pulled When stretching, the core wire may be worn or deformed, which will affect the quality of current or signal transmission. Contents of the invention [0003] In order to solve the technical problems existing in the background technology, the present invention proposes an inner tube buffer conductor limiting anti-interference control cable to avoid dam...
