optical cable for vehicle

Abstract

An optical fiber cable for vehicles, comprising: a main cable (6) and a branch cable (8), wherein the main cable (6) comprises a framework (4), a framework groove being provided on the outer periphery of the framework (4), while optical fiber (3) is laid in the framework groove, and the exterior of the framework (4) is covered by an outer protection sleeve (1); a head of one end or two ends of the main cable (6) is provided with a branching cable protection device (7), one side of the branching cable protection device (7) being connected to the main cable (6), while another side leads out the branch cable (8); the branch cable (8) comprises the optical fiber (3) which branches from the main cable (6) and a casing (10) which is sleeved on the exterior of the optical fiber (3). The structure is simple in structure and lightweight, while being small in size, flexible, having strong lateral pressure resistance, and may be evenly bent such that the optical cable may withstand complex usage environments and may be easily installed in small radius bends in a vehicle. The optical cable has an all-medium structure, may be used in ordinary cars, may be applied in power-on maintenance of high-voltage vehicles, may also be applied in signal monitoring in special high-voltage environments and special strong electric field environments, may be directly pulled out when connected, and is easy to use and install.

Description

technical field [0001] The invention relates to a vehicle optical cable, which belongs to the technical field of communication optical cables. Background technique [0002] With the popularization and development of automobiles and the introduction of smart cars, higher requirements have been placed on the information transmission and signal control systems of automobiles. Traditional automobile information signal transmission systems have been difficult to meet the needs of modern automobiles for large-scale information transmission. Therefore, it has become an inevitable trend to replace traditional metal signal lines with optical cable transmission. On the other hand, due to the special environment in which automobile cables are installed, and the specific functions required by certain automobiles with specific functions, optical cables are required to have better performances such as compression resistance, bending resistance, high voltage resistance and oil resistance. ...

[0002] With the popularization and development of automobiles and the introduction of smart cars, higher requirements have been put forward for the information transmission and signal control systems of automobiles. The traditional automobile information signal transmission system has been difficult to meet the needs of large information transmission in modern automobiles. , therefore, it has become an inevitable trend to replace traditional metal signal lines with optical cable transmission

On the other hand, due to the special environment in which automobile cables are installed, and the specific functions required by certain automobiles with specific functions, optical cables are required to have better performances such as compression resistance, bending resistance, high voltage resistance and oil resistance. Ordinary optical cables are difficult to meet the above specific requirements
