Description

Technical Field

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

[0002] The optical communication module consists of an optical module housing, a fiber optic connector, a transmitting optical component, a receiving optical component, and a printed circuit board. The optoelectronic device includes two parts, the transmitting part and the receiving part. Its function is to convert the electrical signal into an optical signal at the transmitting end. After being transmitted through the optical fiber, the receiving end converts the optical signal into an electrical signal.

[0003] When the existing optical communication module is not in use, its plug-in end does not have a dust-proof structure, so that the plug-in end is exposed to the outside, causing dust to adhere to the outer wall of the gold finger, thereby affecting its conduction effect. At the same time, the use of a traditional plug-in dust plug structure is sealed and dust-proof by plugging in, but static electricity will be generated during the plugging and unplugging process, which can easily damage the electronic devices and circuits inside the optical module housing, further reducing the efficiency and safety of the use of its dust-proof structure. Utility Model Content

[0004] The utility model aims to provide an optical communication module with a dustproof structure to solve the problems of poor dustproof effect and low safety in use proposed in the above-mentioned background technology.

[0005] To achieve the above object, the utility model provides the following technical solution: an optical communication module with a dustproof structure, comprising:

[0006] An optical module integration, wherein the outer wall of the optical module integration is fixedly connected to a limit ring, and one end of the optical module integration is connected to a tow rod;

[0008] Preferably, one end of the optical module integration is a fiber optic interface, and the outside of the fiber optic interface corresponds to the second sleeve, and the other end of the optical module integration is an electrical interface, and the outside of the electrical interface corresponds to the first sleeve.

[0010] Preferably, the inner diameter of the positioning ring is equal to the outer diameter of the optical module assembly, and the inner diameter of the positioning ring is equal to the inner diameter of the limiting ring.

[0011] Preferably, a first rotating shaft is arranged between the first support frames, and the external rotation of the first rotating shaft is connected with the second dust cover, the height of the first support frame is greater than the height of the first sleeve, and the sum of the height of the first sleeve and the thickness of the two sets of second dust covers is equal to the height of the first support frame.

[0012] Preferably, a second rotating shaft is arranged between the second support frames, and the outside of the second rotating shaft is rotatably connected to the first dust cover, the upper and lower ends of the second support frame both extend out of the outer wall of the second sleeve, and the extension distance of the second support frame is equal to the thickness of the first dust cover.
