Description

Technical Field

[0001] This utility model relates to the field of fiber optic sensing technology, and in particular to a vehicle-mounted ruggedized fiber optic matrix. Background Technology

[0002] Modern in-vehicle electronic systems are becoming increasingly complex, integrating multiple functions such as navigation, communication, and entertainment. This necessitates an efficient signal management system to ensure the coordinated operation of various subsystems. As a key signal transmission and distribution device, the in-vehicle ruggedized fiber optic matrix can meet the evolving needs of in-vehicle electronic systems, providing strong support for the realization of intelligent and integrated in-vehicle electronic systems.

[0003] However, in the existing technology, the vehicle-mounted fiber optic matrix is ​​subjected to continuous vibration and impact of varying degrees during vehicle operation, which may cause the fiber optic connections inside the fiber optic matrix to loosen, optical devices to shift or be damaged. Vibration can make the connection between the fiber and the connector unstable, which can easily lead to fiber breakage, connector loosening, etc. This not only affects the signal transmission quality, but may also cause the entire system to fail. For example, during vehicle operation, frequent vibration may accelerate the wear of the ferrule at the fiber optic connector, reduce the coupling efficiency of the fiber, and thus increase signal attenuation.

[0012] As an improved technical solution, the fixing component includes a connecting end that is fixedly connected to the insertion slot. The connecting end has a rotating cavity inside. Support rods are rotatably connected to both sides inside the rotating cavity. A fixing strip is fixedly connected to the bottom end of the support rod.
