Description

Technical Field

[0001] The utility model relates to the technical field of optical modules, in particular to an optical module protection structure. Background Art

[0002] The optical module is composed of optoelectronic devices, functional circuits, and optical interfaces. The optoelectronic devices include two parts: transmitting and receiving. Simply put, the function of the optical module is to convert electrical signals into optical signals at the transmitting end. After transmission through optical fiber, the receiving end converts the optical signals into electrical signals. The announcement number is: CN 219162435U, which discloses a protective mechanism for the optical module, including a protective shell, the upper surface of which is fixedly connected to a sealing shell, and the left and right side surfaces of the sealing shell are fixedly embedded with bearings. The upper surface of the protective shell is provided with two sliding openings, and the inner wall of each sliding opening is slidably connected to a slide. The protective mechanism of the optical module covers the optical module body through a protective shell to protect the optical module body. The threaded connection between the positive and negative threaded rods and the threaded holes can control the slide to drive the bent plate to move, thereby positioning optical module bodies of different models. The elastic force of the spring can push the carrier plate to move up and down, so that the carrier plate can push the optical module body upward, so that optical module bodies of different models can all be moved between the two bent plates, thereby making the device applicable to optical modules of different models, solving the problem that the protective mechanism is not applicable to optical modules of multiple models during use.

[0003] The above solution has the following shortcomings during use: the interface of the optical module body is directly exposed to the outside, which can easily cause dust to accumulate at the interface, resulting in the possibility of device malfunction when connected. At the same time, the connection line of the device connected to the optical module body is easily affected by external forces and shakes. In addition, the shell completely wraps the optical module body, which has poor heat dissipation effect and can easily cause the optical module body to overheat during operation.
