Description

Technical Field

[0001] The utility model relates to the technical field of dustproofing of optical splitters, in particular to a dustproofing structure of a PLC optical splitter. Background Art

[0002] The main reason for dust prevention of PLC optical splitter is to protect its internal precision optical components and circuits, ensure the stable transmission of optical signals and the long-term stable operation of the equipment. Dust and other tiny particles enter the equipment, and the dust will adhere to the surface of optical fiber and optical components, affecting the transmission efficiency and quality of optical signals and increasing optical path loss. Therefore, a dust-proof structure for PLC optical splitter is proposed.

[0003] Patent announcement number CN 216927147 U discloses a PLC optical splitter with dustproof function. The device facilitates the entry of external air through the air flow hole, realizes the heat dissipation effect of the splitter while preventing dust, utilizes the jack to facilitate the insertion of the connector, and the rubber sheet can prevent the possibility of dust entering the interface during a long period of time. The device can play a good dustproof effect, but the air flow hole is exposed to the air for a long time. When the humidity in the air is too high, it is easy to enter the device and affect the internal components. Although the rubber sheet can prevent dust from entering the interface, the dust will accumulate on the outside of the rubber sheet for a long time. When the connector is inserted, the dust will be brought into the interface, thereby affecting the transmission efficiency. In addition, the rubber sheet may be clamped and broken during insertion. Therefore, a dustproof structure of a PLC optical splitter is proposed. Summary of the invention

A plurality of semicircular pressing pieces 4 are fixedly installed on the outer side of the movable plate 5. The movable plate 5 is movably connected in the plug-in slot to facilitate the connection of the rubber sheet 11 with the plug-in hole 6. A spring 10 is connected between the groove and the pressing piece 4. A plurality of plug-in holes are provided on the movable plate 5, and the positions of the plug-in holes and the plug-in holes 6 correspond. A rubber sheet 11 is installed in the plug-in hole, and the plug-in hole 6 and the rubber sheet 11 are movably connected to enable the plug-in hole 6 to push out dust on the outside of the rubber sheet 11.

[0022] In this embodiment, an arc-shaped adjustment groove 14 is provided in the device housing 1, and two arc-shaped closing plates 7 are movably connected in the adjustment groove 14. One end of the closing plate 7 is connected to the inner wall of the device housing 1, and the closing plate 7 is movably connected to the inner notch of the heat dissipation groove. A base 17 is fixedly installed on the outer side of the device housing 1, and two rotating shafts are rotatably connected to the base 17. The first tooth piece 12 and the second tooth piece 16 are respectively welded and installed on one end of the two rotating shafts.
