DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of this patent to clearly and completely describe the technical solutions in the embodiments of this patent. Obviously, the described embodiments are only part of the embodiments of this patent, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0021] See also Figure 1-2 , this patent provides a technical solution: a switch that is easy to disassemble and assemble, including a switch circuit board 1 and a switch housing 2, the switch circuit board 1 is installed in the switch housing 2, an optical fiber connector 3 is installed on the switch circuit board 1, and the optical fiber connector 3 passes through the switch housing 2;

[0022] The switch circuit board 1 and the optical fiber connector 3 proposed in this article are both prior art and consistent with the existing internal circuit board of the switch, wherein the optical fiber connector 3 is an RJ-45 connector;

[0023] The switch housing 2 includes a lower housing 21 and an upper housing 22. A slide groove 4 is provided on the side wall of the lower housing 21. The upper housing 22 is slidably installed in the slide groove 4. A screw 5 is inserted and installed on the side wall of the upper housing 22. The screw 5 can rotate on the upper housing 22. A sleeve 6 is installed on the inner wall of the lower housing 21. An inner wall of the sleeve 6 close to the inner wall of the lower housing 21 is provided with an internal thread. The screw 5 can be inserted into the sleeve 6 and threadedly connected with the sleeve 6.

[0024] The upper housing 22 is slidably mounted on the lower housing 21, so when disassembly is required, only two screws need to be loosened to slide the upper housing 22 out of the lower housing 21, making it convenient to perform maintenance operations inside the switch. Compared with the buckle structure proposed in the background art, the buckle needs to be lifted up by a pry plate during disassembly. The fixed structure proposed in this article is more stable and more convenient for disassembly and assembly;

[0025] In addition, the sleeve 6 provided in this article has only a small section at the tail end provided with threads, so when the screw 5 is loosened, it does not need to be rotated too many times, which is very convenient;

[0026] Cleaning mechanisms 7 are installed on both left and right sides of the lower wall of the upper shell 22;

[0027] The cleaning mechanism 7 can clean the vent holes 12 on the lower shell 21 to prevent dust from affecting the heat dissipation of the device.

[0028] Specifically, the cleaning mechanism 7 includes a connecting tube 71, an air outlet pipe 72, a mesh plate 73 and bristles 74. The connecting tubes 71 are installed on both sides of the upper shell 22. The air outlet pipes 72 are inserted into the side walls of the two connecting tubes 71. The side walls of the air outlet pipes 72 are installed with mesh plates 73. The side walls of the mesh plates 73 are installed with bristles 74. The bristles 74 are in contact with the inner wall of the lower shell 21.

[0029] When the upper shell 22 is Figure 1When the right side of the switch slides, the piston block 11 squeezes the air in the connecting tube 71 out of the air outlet pipe 72 to blow air outward. Under the action of the air flow, the dust scraped off by the bristles 74 can be blown out from the vent hole 12 to prevent dust from falling into the switch.

[0030] Specifically, an arc plate 8 is installed on the inner wall of the lower shell 21. There are two arc plates 8. The two arc plates 8 are respectively located below the two connecting cylinders 71. The arc plates 8 are in contact with the outer wall of the connecting cylinder 71. A support rod 9 is installed on the upper wall of the arc plate 8. A through groove 10 is opened on the lower wall of the connecting cylinder 71. The support rod 9 passes through the through groove 10 and penetrates the side wall of the connecting cylinder 71. A piston block 11 is installed, and the piston block 11 can slide in the connecting cylinder 71.

[0031] The arc-shaped plate 8 can shield the through slot 10 , so that when the upper housing 22 is slid, airflow is prevented from flowing out of the through slot 10 as much as possible.

[0032] Specifically, a vent hole 12 is formed on the side wall of the lower housing 21 , and the vent hole 12 and the mesh plate 73 are on the same horizontal line.

[0033] Specifically, a rotating handle 13 is installed at one end of the screw rod 5 located outside the upper housing 22 .

[0034] Specifically, a sealing gasket 14 is fitted on the upper wall of the arc-shaped plate 8, and the sealing gasket 14 fits the side wall of the connecting tube 71;

[0035] The tightness of the connection between the arc plate 8 and the connecting tube 71 can be further improved by providing the sealing gasket 14 .

[0036] Working principle: When the switch needs to be disassembled and repaired, the two screws can be loosened and the upper shell 22 can be slid out to expose the switch circuit board 1 inside the switch shell 2 for repair. In the process of sliding the upper shell 22, the bristles 74 will clean the vent 12. At the same time, the piston block 11 will squeeze the air in the connecting tube 71 out of the air outlet pipe 72 to blow it outward. Under the action of the air flow, the dust scraped off by the bristles 74 can be blown out from the vent 12 to prevent dust from falling into the switch.
