Compression cable

Abstract

The invention discloses a compression-resisting cable. The compression-resisting cable comprises a cable body and a cable connector device, wherein a liquid lubricating agent layer fills between a protective layer and a metal cable core so that the protective layer and the metal cable core are not in contact, the cable body is provided with a pull-partitioning pad, and the pull-partitioning pad is an elastic bag body filled with a liquid lubricating agent; and the cable connector device is composed of butt-joint parts arranged on two sides and a connecting part arranged in the middle, the connecting part comprises cable core insertion holes with same number of cable wires, a contact block is arranged in each cable core insertion hole, the contact blocks are connected with guide cores through springs, each butt-joint part comprises a first pressing part and a second pressing part, and each first pressing part comprises cable wire insertion holes communicated with the cable core insertion holes, a first pressing shell body and a flexible filling layer filling between the first pressing shell body and the cable wire insertion holes. The compression-resisting cable has the advantage of excellent compression resistance.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to compression cables. Background technique [0002] Cables include power cables, compression 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 multi-strand wires and insulation layers, and are used to connect circuits, electrical appliances, etc. [0003] For some environments where no cables are erected, such as construction sites, the cables are easily broken by passing vehicles. The mechanism of the breakage is analyzed. The cable core sheath is pressed on the cable core under high pressure, so that the sheath and The cable core produces a large friction, and then the sheath is axially deformed under pressure, which produces an axial pulling force on the cable core, causing the cable core to be pu...

[0003] For some environments where no cables are erected, such as construction sites, the cables are easily broken by passing vehicles. The mechanism of the breakage is analyzed. The cable core sheath is pressed on the cable core under high pressure, so that the sheath and The cable core produces a large friction, and then the sheath is axially deformed under pressure, which produces an axial pulling force on the cable core, causing the cable core to be pulled off

At the same time, part of the cable was broken because there were sharp objects such as stones in the lower part of the cable. When the car rolled over, the stone pierced the cable and caused the cable to break
