[0001] The utility model relates to the technical field of photoelectric composite cables, in particular to a flexible anti-twist shielding photoelectric composite cable. [Background Technology]

[0002] With the acceleration of global industrialization and the continuous advancement of intelligent manufacturing technology, the demand for efficient and reliable transmission solutions is growing. Especially in the field of industrial automation and intelligence, the demand for a composite cable that can transmit electrical energy and optical signals at the same time has become particularly urgent. This composite cable plays a vital role in modern industrial systems. They are not only used to connect various robots, robotic arms, intelligent devices and sensors, but also widely used in remote monitoring, data communication and energy distribution. In addition, this cable is used as a transmission line in the broadband access network system. It is a new access method that integrates optical fiber and power transmission copper wire, which can solve the problems of broadband access, equipment power consumption and signal transmission.

[0003] However, existing optoelectronic composite cables face a series of challenges in practical applications. Due to the complexity and variability of the industrial environment, cables often encounter torsion, bending or other mechanical stresses during use, which may cause damage to the cable structure and affect the transmission quality of power, electrical signals and optical signals. Cable damage will not only reduce the overall performance of the system, but may also cause data loss, communication interruption and even safety accidents, bringing serious consequences to industrial production. In addition, electromagnetic interference and electrical noise in industrial environments are also important factors affecting cable performance, and effective shielding measures are needed to ensure the clarity and accuracy of signals.

[0004] In order to solve these problems, it is urgent to develop a new type of optoelectronic composite cable, which should have excellent anti-torsion performance, anti-interference ability and shielding and anti-electric shock function. Such a cable can maintain stable transmission of power, electrical signals and optical signals under harsh working conditions, while resisting external electromagnetic interference to ensure the safety and reliability of communication. The design of this cable needs to take into account the selection of materials, optimization of structure and enhancement of protective measures to ensure that the internal optical fiber and conductor of the cable can minimize the risk of damage when facing torsion, bending and other mechanical stresses. Through such a design, the new optoelectronic composite cable will greatly improve the reliability and stability of industrial automation systems, meet the needs of future intelligent manufacturing for efficient and durable transmission solutions, and ensure the safety of personnel and equipment.
