Bending-resistant flexible cable

Abstract

The present invention discloses a bending-resistant flexible cable, including an anti-bending element, a cable core, a wrapping layer, a woven reinforcement layer and a wear-resistant sheath layer that are sequentially distributed from the inside to the outside. The anti-bending element includes a reinforcement core and an elastic sheath. A plurality of curved segments are evenly disposed around the outer side of the reinforcement core. The elastic sheath is sleeved on the outer side of the reinforcement core. A plurality of splitting segments are evenly arranged around the outer side of the elastic sheath. A pair of cable cores are disposed between adjacent splitting segments. A shielding rubber sleeve is disposed on an outer side of the cable core, and the shielding rubber sleeve is internally filled with a plurality of lead bead chains. The wrapping layer is disposed on the outer side of the cable core, the woven reinforcing layer is disposed on the outer layer of the wrapping layer, and the outer side of the woven reinforcing layer is extruded with the wear-resistant sheath layer. In the present invention, the cable can have strong resistance to bending and deformation, has a reasonable structure, is not easy to be bent and damaged, and has a long service life, and is favorable for popularization and application.

Description

【Technical field】 [0001] The invention relates to the technical field of cables, in particular to the technical field of a bending-resistant flexible cable. 【Background technique】 [0002] Flexible cables are the preferred cables for power transmission materials and signal transmission carriers in towline motion systems, also known as: towline cables, tow cables, mobile cables, robot cables, etc. The sheath of the flexible cable is mostly made of low-viscosity flexible wear-resistant material to slow down the wear rate of the cable during continuous reciprocating movement. The flexible cable often needs to be bent and dragged during use, and the cable core and its outer sheath will be constantly damaged. To withstand a certain range of twisting and deformation, due to the lack of a suitable protective structure, the flexible cable is prone to damage, core wire breakage and other faults during the bending process, which seriously affects the use effect. 【Content of inventio...

The sheath of the flexible cable is mostly made of low-viscosity flexible wear-resistant material to slow down the wear rate of the cable during continuous reciprocating movement. The flexible cable often needs to be bent and dragged during use, and the cable core and its outer sheath will be constantly damaged. Under a certain range of twisting and deformation, due to the lack of a suitable protective structure, the flexible cable is prone to damage, core wire breakage and other faults during the bending process, which seriously affects the use effect
