Anti-torsion and environment-resistant ultra-flexible cable for field photography

Abstract

The invention discloses an anti-twist environment-resistant super soft cable for field photography. The super soft cable is composed of a plurality of insulation cable cores and a buffer protection outer layer. The buffer protection outer layer wraps the insulation cable cores. Reinforcing ribs are arranged between the insulation cable cores. Each insulation cable core comprises a soft guide body, an insulation layer and an aromatic hydrocarbon weaving layer. The buffer protection outer layer sequentially comprises a cable-forming wrapping band layer, a steel wire weaving layer and an outer protection layer from inside to outside. Each soft guide body is formed by binding and then wenching a plurality of thin anaerobic copper wires. Each insulation layer is formed by extruding and wrapping vulcanization-free ethylene propylene rubber elastic body composite. Each aromatic hydrocarbon weaving layer is formed by weaving high-strength aromatic hydrocarbon fiber yarn. The reinforcing ribs are formed by processing fine tawny daylily hemp ropes or high-strength composite. The cable-forming wrapping band layer is formed by winding and wrapping polyester belts. The steel wire weaving layer is formed by weaving a plurality of fine steel wires. The anti-torque environment-resistant super soft cable can meet requirements for special lighting wires and cables, and equipment connection cables used by film and television equipment in telecast halls and studios, can meet the requirements of wild photography work, and is widely used in film and television hall construction, photographic equipment operation and outdoor photography work.

Description

Technical field: [0001] The invention relates to a light source cable, in particular to a twist-resistant and environment-resistant ultra-flexible cable for field photography, which can be used in harsh and complex environments and is a special special cable for photography. Background technique: [0002] In the power supply or data control lines of frequently moving photographic mechanical equipment, especially in field photography, with the dragging of continuous and frequent reciprocating movements, as well as the damage of the external environment and artificial mechanical forces, the cables used for laying are always in a dynamic state. In the state of winding motion, the cable conductor bears the main moving traction. During the moving process, the bending radius of the cable is only several times of its own outer diameter. After thousands of reciprocating movements, under high-speed and high-frequency conditions, the copper stranded conductor of ordinary flexible cabl...

AI Technical Summary

Problems solved by technology

During the moving process, the bending radius of the cable is only several times of its own outer diameter. After thousands of reciprocating movements, under high-speed and high-frequency conditions, the copper stranded conductor of ordinary flexible cables often undergoes yield fatigue and core breakage. , the service life is only one to two months, and because there is no protective layer against mechanical force, and the sheath layer is often made of ordinary rubber material, it is prone to cracking when it is frequently twisted and moved

Due to the damage of the cable, the pause and disorder of the entire photography, editing and broadcasting work frequently occur. In this type of industry, the cable used for frequent movement is a kind of fast-wearing device.
