A high anti-interference trolling cable

Abstract

The invention discloses a high anti-interference towing cable, comprising an outer sheath and an inner sheath, the inner surface of the outer sheath is pasted with a rubber layer, the outer surface of the rubber layer is provided with a metal coating block, and the The inner two sides of the rubber layer are symmetrically embedded with steel cables, the outer surface of the inner sheath is wrapped with an outer metal shielding layer, and the outer surface of the outer metal shielding layer is wrapped with an insulating layer, and the inner sheath is embedded There is a fiber core, the lower surface of the cushion block is elastically connected with the pressure block through the pasted shock-absorbing ball, and the inner side of the pressure block is provided with a conductor. In the present invention, the towed cable adopts the structure of inner and outer double-layer metal shielding layers, which can play the role of double-layer anti-interference protection for the fiber core in the towed cable, realize the independent protection effect of inner and outer layers, and at the same time metal shielding The layer adopts the structure design of three-layer twisted-pair structure metal wire, which further maximizes the blocking effect of external electromagnetic interference signals and ensures the safe use of the towed cable.

Description

technical field [0001] The invention relates to the technical field of trolley cables, in particular to a trolley cable with high anti-interference. Background technique [0002] Originally designed for the power transmission and signal transmission of the trolley system, so as to control the crane, hoist or any equipment that moves laterally. , it can be used in places with limited space, or in places with extremely high bending requirements. The cables are generally soft and resistant to bending, and have a wide range of applications. [0003] However, in the anti-interference protection measures of the existing towed cables, usually only the structure of a single-layer shielding layer is used for anti-interference protection. Comprehensive blocking makes the trolley cable susceptible to interference, which in turn reduces the stability of the trolley cable for data information transmission. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to p...

Problems solved by technology

[0003] However, in the anti-interference protection measures of existing tow cables, usually only a single-layer shielding layer structure is used for anti-interference protection. Due to the different frequencies of external electromagnetic interference models, the single-layer and single-structure shielding layer cannot protect against electromagnetic interference signals. Carry out comprehensive blocking, causing the tow cable to be easily affected by interference, thereby reducing the stability of the tow cable to the transmission of data information
