Description

Technical Field

[0001] The utility model relates to the technical field of wavelength division multiplexers, in particular to a dustproof structure for wavelength division multiplexers. Background Art

[0002] During the use of optical fiber, in order to facilitate the transmission of optical signals of different wavelengths through one optical fiber, workers usually use the optical fiber line in conjunction with a wavelength division multiplexer. The plug interface of the wavelength division multiplexer is usually directly exposed to the outside, and dust can easily enter the plug interface of the wavelength division multiplexer, causing interference to the optical signal during transmission, thereby reducing the quality of the optical signal.

[0003] After searching, an integrated wavelength division multiplexer is proposed according to the Chinese utility model application number CN202221817796.6, and its invention content records that "this integrated wavelength division multiplexer is provided with a closed dust cover on the wavelength division multiplexer body for automatically closing the plug interface, thereby preventing dust from entering the plug interface, wherein under the action of the elastic opening of the arched spring piece, two pairs of cover plates arranged opposite to each other are closed, thereby automatically closing the plug interface and playing a dust-proof role. When in use, the closed dust cover is manually opened through a functional block provided on the cover plate, so that the optical fiber is inserted into the plug interface, and when the optical fiber is pulled out of the plug interface, under the action of the elastic opening of the arched spring piece, the two pairs of cover plates arranged opposite to each other are closed, thereby automatically closing the plug interface."

[0004] Among them, when inserting the optical fiber into the corresponding plug-in port of the integrated wavelength division multiplexer, it is necessary to keep the two covers open with fingers, which increases the difficulty of inserting the optical fiber. When the optical fiber is taken out from the corresponding plug-in port, the arched spring piece may decay due to long-term force, resulting in a decrease in elastic force. A gap may be generated after the two covers are closed, and dust may contaminate the plug-in port through the gap between the two covers, affecting the dustproof effect. Therefore, a dustproof structure for a wavelength division multiplexer is proposed to solve the above problems. Utility Model Content

[0008] Furthermore, slide grooves are provided on both left and right sides of the inner wall of the shell, and the two slide grooves are matched with the baffle, and a handle is fixedly installed on the front of the baffle.

The baffle is moved upward, and the baffle drives the first magnet to move upward. The first magnet and the second magnet are magnetically attracted to each other.
