Description

Technical Field

[0001] The present invention belongs to the field of switches, and particularly relates to a POE switch with a waterproof function. Background Art

[0002] A POE switch is a network switching device that can transmit data and electricity simultaneously through an Ethernet cable. Based on PoE technology, it allows power to be provided to PoE-enabled devices through a standard Ethernet cable without the need for additional power cords or local power supplies.

[0003] As one of the core devices to implement this technology, the application of PoE switches in indoor environments has been very mature. However, when these devices are deployed outdoors or in high-humidity environments, the following problems still exist:

[0004] 1. Insufficient waterproof performance: Although some PoE switches may have basic waterproof designs, these designs are usually not sufficient to cope with continuous moisture. For example, key parts such as network ports lack effective sealing measures, making it easy for moisture to enter, which can lead to corrosion of internal components.

[0005] 2. Prone to rust: Due to being in a humid environment for a long time, especially metal parts such as the housing and interfaces are prone to oxidation, forming rust. This corrosion not only affects the appearance, but more importantly, it will damage the electrical performance, shorten the service life of the device, and may cause problems such as network interruption.

[0006] Therefore, there is an urgent need to develop a POE switch with a waterproof function to solve the above technical problems. Summary of the Invention

[0007] In order to overcome the above-mentioned disadvantages of the prior art, the technical problem of the present invention is: to provide a POE switch with a waterproof function.

[0008] The technical solution of the present invention is: A POE switch with a waterproof function, comprising a switch body, a mounting housing, a sliding housing, and an interface sealing mechanism. There is a mounting housing on the switch body. The sliding housing is slidably connected to the interface position of the mounting housing.

A clamping plate is provided at the top of the sliding ring, and the sliding ring is stuck in the clamping plate.

[0011] Furthermore, the interface sealing mechanism further includes a spring I and a spring II. A spring I is connected between the pressing ring and the guide rod I, and a spring II is connected between the left side of the sliding ring and the left end of the guide rod II.

[0012] Furthermore, the interface sealing mechanism further includes a sealing strip. A sealing strip is provided at the contact surface between the interface protection bottom shell and the interface protection upper shell. A placement groove having the same shape as the sealing strip is provided on the interface protection upper shell above the sealing strip.

[0013] Furthermore, a clamping structure is further included. A clamping structure is provided between the installation outer shell and the sliding outer shell.

[0031] Embodiment: A POE switch with a waterproof function, as Figures 1-3 、 Figures 5-7 shown, includes a switch body 1, a mounting housing 101, a sliding housing 102 and an interface sealing mechanism 3. There is a mounting housing 101 on the switch body 1. A through hole for fixing the switch body 1 is opened on the mounting housing 101 to facilitate the fixing of the switch body 1. A sliding housing 102 is slidably connected to the interface position of the mounting housing 101. The edge of the sliding housing 102 is L-shaped to strengthen the strength of the sliding housing 102. The sliding housing 102 cannot slide out of the mounting housing 101. A wire passing port 103 is opened on the right wall of the sliding housing 102, so that the external network cable enters the mounting housing 101 and the sliding housing 102 through the wire passing port 103 and is connected to the switch body 1. An interface sealing mechanism 3 is provided at the right interface of the switch body 1. The interface sealing mechanism 3 is used to prevent water vapor from entering the switch body 1 interface.

[0032] As Figures 5-7As shown, the interface sealing mechanism 3 includes an interface protection bottom shell 301, an interface protection upper shell 302, an elastic sleeve 303, a guide rod I 304, a pressure ring 305, a spring I 306, a guide rod II 307, a sliding ring 308, a card plate 309, a spring II 3010 and a sealing strip 3011. The interface of the switch body 1 is provided with an interface protection bottom shell 301, and an interface protection upper shell 302 is provided on the upper part of the interface protection bottom shell 301. The interface protection upper shell 302 is rotatably connected with the interface protection bottom shell 301. The contact surface of the interface protection bottom shell 301 and the interface protection upper shell 302 is provided with a sealing strip 3011. The interface protection upper shell 302 above the sealing strip 3011 is provided with a placement groove consistent with the shape of the sealing strip 3011. The right sides of the interface protection bottom shell 301 and the interface protection upper shell 302 are both provided with elastic sleeves 303. The sex sleeve 303 is conical, and guide rods I 304 are symmetrically arranged at the bottom of the interface protection bottom shell 301. A pressure ring 305 is slidably connected between the guide rods I 304. The inner side of the pressure ring 305 is an inclined surface, which is retracted from the left to the right. A spring I 306 is connected between the pressure ring 305 and the guide rod I 304. A guide rod II 307 parallel to the guide rod I 304 is arranged on the top of the interface protection upper shell 302. A sliding ring 308 is slidably connected on the guide rod II 307. A spring II 3010 is connected between the left side of the sliding ring 308 and the left end of the guide rod II 307. A clamping plate 309 is arranged on the top of the sliding ring 308, and the sliding ring 308 is clamped in the clamping plate 309. When the interface protection upper shell 302 is rotated upward to open, the sliding ring 308 is separated from the clamping plate 309, and when the interface protection upper shell 302 is rotated downward to close, the sliding ring 308 is clamped in the clamping plate 309.

[0033] like Figure 4 As shown, a clamping structure 2 is also included. A clamping structure 2 is provided between the mounting shell 101 and the sliding shell 102. The clamping structure 2 includes a clamping block 202 and a torsion spring 203. The right outer portions of the front and rear walls of the mounting shell 101 are rotatably connected with the clamping block 202. The left portion of the clamping block 202 is tilted outward, and the rear portion of the clamping block 202 is an inclined surface extending inward. A torsion spring 203 is provided at the rotational connection between the clamping block 202 and the mounting shell 101. The front and rear walls of the sliding shell 102 are both provided with clamping grooves 201, and the clamping block 202 can be clamped into the clamping grooves 201.

[0034] like Figure 8 and Figure 9As shown, it further includes an outlet sealing structure 4. The sliding outer shell 102 at the wire passing port 103 is provided with the outlet sealing structure 4. The outlet sealing structure 4 includes a collar 401, an L-shaped hollow rod 402, a piston rod 403, a push plate 404, a spring III 405 and an airbag 406. Collars 401 are provided on the sliding outer shell 102 at the wire passing port 103. L-shaped hollow rods 402 are evenly spaced on the sliding outer shell 102 outside the collar 401. Two L-shaped hollow rods 402 form a group, respectively above and below the collar 401. Piston rods 403 are slidably connected to the left parts inside the L-shaped hollow rods 402. The push plate 404 is connected to the left end of each group of piston rods 403. When the push plate 404 moves leftward, it can contact the pressure ring 305. A spring III 405 is connected between the piston rod 403 and the L-shaped hollow rod 402. An airbag 406 is connected between the right ends of the L-shaped hollow rods 402. The airbag 406 is annular. The axis of the airbag 406, the axis of the collar 401, the center of the push plate 404 and the center of the pressure ring 305 are on the same horizontal line.

[0035] When the interface of the Ethernet cable needs to be plugged into the switch, first, the left part of the latch 202 needs to be pressed inward. At this time, the torsion spring 203 deforms, and the right part of the latch 202 no longer locks in the card slot 201. Then, the sliding outer shell 102 is pulled to the right until Figure 1 the state, and then the interface of the Ethernet cable is inserted into the left side of the sliding outer shell 102 from the collar 401. Then, the interface protection upper shell 302 is rotated upward to Figure 7 the state, so that the interface of the Ethernet cable can be better docked with the switch body 1. The interface of the Ethernet cable passes through the pressure ring 305 and the interface protection bottom shell 301 and is docked with the switch body 1 well. Then, the interface protection upper shell 302 is rotated back to Figure 6In this state, the sliding housing 102 is then pushed to move leftward to close with the mounting housing 101. At this time, the pushing plate 404 moves leftward to contact the pressure ring 305, and the pressure ring 305 is pushed to move leftward to squeeze the elastic sleeve 303. The spring I 306 and the spring II 3010 are compressed, so that the elastic sleeve 303 can tightly fit on the outer surface of the Ethernet cable, ensuring no gap between the Ethernet cable and the elastic sleeve 303, preventing water vapor from entering the interface. At the same time, the interface protection bottom shell 301 and the interface protection upper shell 302 are pressed against each other. Due to the presence of the sealing strip 3011, the gap between the protection bottom shell and the interface protection upper shell 302 is filled, preventing water vapor from entering through the gap between the protection bottom shell and the interface protection upper shell 302, further preventing water vapor from entering. When the pushing plate 404 moves leftward to contact the pressure ring 305, under the action of the reaction force, the piston rod 403 enters the L-shaped hollow rod 402, and the spring III 405 is compressed. The gas in the L-shaped hollow rod 402 enters the airbag 406, causing the airbag 406 to expand. The inner surface of the airbag 406 tightly fits on the outer surface of the Ethernet cable, and the outer surface of the airbag 406 fits with the collar 401. In this way, external water vapor cannot enter the mounting housing 101 and the sliding housing 102, further preventing moisture from entering. When it is necessary to open the mounting housing 101 and the sliding housing 102 to repair the switch body 1, first press the left part of the latch 202 inward, causing the latch 202 to disengage from the card slot 201. At this time, under the action of the reset of the spring I 306, the spring II 3010 and the spring III 405, the sliding housing 102 moves outward and resets. At the same time, the L-shaped hollow rod 402 resets, and the gas in the airbag 406 returns to the L-shaped hollow rod 402, and the airbag 406 shrinks and no longer fits the Ethernet cable and the collar 401. Subsequently, the interface protection upper shell 302 is rotated to Figure 7 this state, so the sliding ring 308 is stuck in the clamping plate 309, and the clamping plate 309 does not hinder the upward rotation of the interface protection upper shell 302 and its upper components. Subsequently, the switch body 1 can be repaired.

[0036] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
