Description

Technical Field

[0001] This utility model relates to the field of sealing and isolation technology for optical cables and electrical cables, specifically to an optical fiber sealing chamber device. Background Technology

[0002] In many industrial, scientific, and military applications, optical devices (such as optical sensors, optical switches, optical amplifiers, and detectors) need to operate in harsh environments, such as high humidity, underwater, corrosive atmospheres, high pressure, vacuum, or environments containing dust and contaminants. These environmental factors can lead to performance degradation and shortened lifespan of optical devices, or increase losses or even cause failure of fiber optic connections. Therefore, it is necessary to encapsulate these sensitive optical devices or connections in a sealed cavity that provides effective protection.

[0003] Achieving a sealed cavity is not difficult, but a key technical challenge is how to reliably connect optical fibers while ensuring the cavity is sealed and that the seal at the connection point is effective for a long time without damaging the fiber.

[0004] However, traditional fiber optic access sealing methods have some problems: their reliability, pressure resistance and ease of operation are significantly insufficient in applications that need to withstand high external pressure (such as deep-water applications) or require frequent plugging and unplugging of connectors. Utility Model Content

[0005] To address the aforementioned problems, the purpose of this utility model is to provide a fiber optic sealed chamber device that can effectively protect internal optical devices and fiber optic connection points, and achieve safe, reliable fiber optic access and sealing.

A device mounting bracket is fixedly disposed in the second-level sealed cavity, and optical and electronic devices are disposed on the device mounting bracket. A ferrule component and an electrical connector socket are respectively provided through the end face of the end cap. An optical fiber sealing plug and a sealing pin are disposed on the closed end face of the isolation cylinder. After the optical cable is connected to the ferrule component, the optical fiber in the optical cable passes through the ferrule component and enters the first-level sealed cavity, then passes through the optical fiber sealing plug and enters the second-level sealed cavity to connect with the optical device. After the cable is connected to the electrical connector socket, the wire in the cable passes through the electrical connector socket and enters the first-level sealed cavity, then passes through the sealing pin and enters the second-level sealed cavity to connect with the electronic device.

[0008] Preferably, in the optical fiber sealing chamber device, one end of the device mounting bracket is connected to the end face of the closed end of the isolation cylinder via a first connector.

[0009] Preferably, in the fiber optic sealed chamber device, a first O-ring is provided at the contact point between the outer wall of the isolation cylinder and the inner wall of the protective cylinder.
