Embodiment Construction

[0015] refer to figure 1 , the present invention proposes an elastic anti-bending control cable, including a cable core and a flame-retardant tape wrapping layer 1 wrapped outside the cable core, an inner sheath 2, a tinned copper wire braided shielding layer 3 and an outer sheath 4. The cable core includes a central support tube 5, a central control core, and a plurality of outer control cores 7, wherein:

[0016] The central support tube 5 is arranged at the center of the cable and the central support tube 5 is made of a hard material. The central support tube 5 is provided with a central cavity 51 extending along the axial direction of the cable. The central support tube 5 is provided with a plurality of To the extending cooling chamber 52, the cooling chamber 52 is filled with coolant, and the outer periphery of the central support pipe 5 is provided with a plurality of rigid supports 8 arranged radially along the cable, and the plurality of rigid supports 8 are arranged o...

Abstract

The invention provides an elastic anti-bending control cable, which comprises a cable core, a flame-retardant band wrapping layer, an inner sheath, a tinned copper wire braided shielding layer and anouter sheath, wherein the flame-retardant band wrapping layer, the inner sheath, the tinned copper wire braided shielding layer and the outer sheath are wrapped outside the cable core in sequence. A center support pipe is peripherally provided with a plurality of rigid supports distributed in the radial direction of a cable; the end, away from the center support pipe, of each of the plurality of rigid supports is provided an elastic support member; a plurality of external control cores are arranged in the plurality of elastic support members respectively; a center control core is arranged in the center support pipe; and the inner sides of the plurality of external control cores are abutted against the inner circle surfaces of the plurality of elastic support members and the outer sides ofthe plurality of external control cores are abutted against the flame-retardant band wrapping layer respectively, thereby ensuring tightness of the control cable. When the cable is bent due to external force, the elastic support members and a plurality of elastic tubes deform to achieve a buffer effect for bending of the control cable; and when the bending force fades away, the elastic support members and the plurality of elastic tubes recover under the resilience actions thereof, thereby ensuring that the whole cable is smooth and straight, and not influencing current or signal transmission quality.

Description

technical field [0001] The invention relates to the technical field of control cables, in particular to an elastic and anti-bending control cable. Background technique [0002] With the rapid development of science and technology, the application of electronic computers and instruments is becoming more and more popular, people's safety awareness is constantly increasing, and the performance of the cables matching it is also constantly improving. Some cables used in specific environments require strong bending resistance to prevent the cables from breaking during use, affecting work and causing a lot of waste of resources. This requires improving the bending resistance of the cable to avoid interruption of transmission due to the inability of the cable to withstand strong enough bending resistance. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes an elastic anti-bending control cable. ...
