Description

Technical Field

[0001] The utility model relates to the technical field of switches, in particular to a switch with dual power supply circuits. Background Art

[0002] A switch is a network device used for forwarding electrical signals. It can provide an exclusive electrical signal path for any two network nodes connected to the switch. The most common switch is the Ethernet switch. Other common switches include telephone voice switches and fiber optic switches. In daily life, we often need to use a switch with a dual power supply circuit.

[0003] Switches in the prior art are generally directly exposed to the external environment during use. This will cause dust and other impurities in the external environment to accumulate on the outside of the switch or enter the inside of the switch, thereby causing damage to the switch and affecting the normal use of the switch. In addition, when objects in the external environment accidentally hit the switch, it will also cause damage to the switch. Moreover, switches in the prior art do not have an effective heat dissipation structure, and a large amount of heat will be generated during the operation of the switch. At this time, if the switch is not heat-dissipated, it will be difficult to discharge the heat inside the switch, thereby reducing the service life of the switch.

[0004] Compared with the Chinese patent publication number CN215897757U, the present invention discloses a switch with a dual power supply circuit. The present invention includes a body, an Ethernet interface is installed at one end of one side of the body, an automatic transfer switch is installed at the middle position of the middle position of one side of the body, and a power switch and a power connection port are installed at the end of the side of the body away from the Ethernet interface. The shell of the present invention is composed of a body and an L-shaped top cover. Since there are slide grooves at the top of both ends of the body, the L-shaped top cover is connected to the body through the slide grooves, and the L-shaped top cover and the body are further connected by bolts and nuts inside the body. When the switch fails, the maintenance personnel only need to remove the two bolts to pull the L-shaped top cover out from the top of the body. This not only makes it convenient for the maintenance personnel to disassemble the switch, but also improves the maintenance efficiency of the maintenance personnel. In addition, the switch shell will not be damaged during the disassembly process.

[0005] The above solution can easily disassemble the switch, but the switch in the above solution is still directly exposed to the external environment during use. Moreover, the switch in the above solution still does not have an effective heat dissipation structure during use, and fails to solve the problems raised in the above background technology.

[0006] Therefore, those skilled in the art provide a switch with a dual power supply circuit to solve the problems raised in the above background technology. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] See also Figure 1- Figure 8 As shown, this embodiment provides a switch with a dual power supply circuit, including a protective housing 1 and further comprising:

[0033] A support plate 8 is fixedly connected to the interior of the protective housing 1, and a switch body 9 is provided on the upper surface of the support plate 8;

[0034] A fixing assembly is provided at the bottom of the support plate 8 and is used to fix the switch body 9;

[0035] The positioning frame 2 is fixedly connected to the outside of the protective shell 1, and a closing cover 3 is provided inside the positioning frame 2;

[0036] The mounting assembly is symmetrically arranged on both sides of the outer wall of the positioning frame 2 and is used to fix the positioning frame 2 and the closing cover 3;

[0037] The heat dissipation component is symmetrically arranged inside the closed cover 3 and is used to dissipate heat from the switch body 9;

[0038] The dustproof component is located above the closing cover 3 and is used to perform dustproof protection on the interior of the protective housing 1 .

[0039] The above working principle: when the switch body 9 needs to be installed and used, it is only necessary to place the switch body 9 on the support plate 8 first, and then use the fixing component to fix and clamp the switch body 9. At this time, the switch body 9 can be prevented from being displaced inside the protective shell 1, etc., which effectively improves the stability of the switch body 9 during operation. After the switch body 9 is installed, the positioning frame 2 and the closing cover 3 are fixed by the installation component. At this time, the switch body 9 can be effectively protected by the cooperation between the closing cover 3 and the protective shell 1, thereby effectively extending the service life of the switch body 9. During the operation of the switch body 9, a large amount of heat will be generated. At this time, the heat dissipation component starts to operate, and the heat dissipation component can effectively dissipate heat for the switch body 9, thereby further extending the service life of the switch body 9. Through the setting of the dustproof component, the dustproof effect of the device as a whole on the switch body 9 can be further improved, effectively improving the overall practicality of the device, saving time and effort.

[0040] In order to effectively fix the switch body 9, the fixing assembly includes a fixing plate 11 fixedly connected to the bottom of the support plate 8, the interior of the fixing plate 11 is fixedly connected to the inner plate 12, and the outer walls of the inner plate 12 are fixedly connected to sliding rods 25 on both sides, and the other ends of the two sliding rods 25 are respectively fixedly connected to the inner walls of the fixing plate 11 on both sides, and the interior of the fixing plate 11 is symmetrically provided with a contact plate 13, and the interior of the two contact plates 13 is provided with a guide groove for the movement of the sliding rods 25. The outside of the two sliding rods 25 is sleeved with a return spring 26, and the two return springs 26 are in contact between the contact plate 13 and the fixing plate 11. The outside of the contact plate 13 is symmetrically provided with connecting rods 27, and the other end of each two connecting rods 27 extends to the outside of the protective shell 1 and is fixedly connected to the connecting plate 14. The outsides of the two connecting plates 14 are fixedly connected with pull rings, and the opposite sides of the two connecting plates 14 are fixedly connected to the clamping plate 29 through the outer plate 28. When the switch body 9 needs to be fixed, just pull When the pull ring is moved, the pull ring will drive the connecting plate 14 to move synchronously, and the connecting plate 14 will drive the connecting rod 27 to move synchronously, and the connecting rod 27 will drive the contact plate 13 to move synchronously on the outside of the sliding rod 25. During the movement of the contact plate 13, the reset spring 26 will be squeezed, and the connecting plate 14 will also drive the outer plate 28 and the clamping plate 29 to move synchronously. At this time, the switch body 9 is placed on the upper surface of the support plate 8, and the pull ring is released again. At this time, the reset spring 26 is reset, driving the contact plate 13 to move synchronously, and the contact plate 13 again drives the connecting rod 27 and the connecting plate 14 to move synchronously, and the connecting plate 14 again drives the outer plate 28 and the clamping plate 29 to move synchronously. When the clamping plate 29 contacts the outside of the switch body 9, the switch body 9 can be effectively fixed and clamped by the clamping plate 29, thereby preventing the switch body 9 from being displaced inside the protective shell 1, and effectively improving the stability of the switch body 9 during use.

[0041] Taking into account that when the switch body 9 is protected, the closing cover 3 and the protective shell 1 need to be closed and fixed, so the installation component includes guide rods 20 symmetrically arranged on both sides of the outer wall of the positioning frame 2, and the other ends of the multiple guide rods 20 are fixedly connected to the limit disk 21. The outside of each two guide rods 20 is slidably connected with a movable plate 22, and the outside of the multiple guide rods 20 are sleeved with a resistance spring 23. The multiple resistance springs 23 are in resistance between the movable plate 22 and the limit disk 21. The outside of the movable plate 22 is fixedly connected with a handle, and the opposite side of the two movable plates 22 is fixedly connected with an insertion plate 24. Guide grooves for the movement of the insertion plate 24 are provided on both sides of the outer walls of the positioning frame 2, the protective shell 1 and the closing cover 3. When it is necessary to install the closing cover 3 and the protective shell 1, you only need to pull the handle first. At this time, the handle will drive the movable plate 22 to move synchronously outside the guide rod 20. During the movement of the movable plate 22, the resistance spring 23 will be squeezed, and the movable plate 22 will also drive the plug plate 24 to move synchronously. At this time, the closing cover 3 is inserted into the interior of the positioning frame 2, and the handle is released. At this time, the resistance spring 23 is reset, driving the movable plate 22 to move synchronously, and the movable plate 22 then drives the plug plate 24 to move synchronously. When the plug plate 24 is inserted into the guide grooves on both sides of the outer wall of the closing cover 3, the closing cover 3 and the positioning frame 2 can be fixed. At this time, the closing cover 3 and the protective shell 1 can be fixedly installed, so that the switch body 9 can be effectively protected by the cooperation between the closing cover 3 and the protective shell 1, thereby effectively extending the service life of the switch body 9.

[0042] In order to effectively dissipate heat for the switch body 9, mounting holes are symmetrically opened on the upper surface of the closing cover 3. The heat dissipation assembly includes a cooling fan 10 fixedly connected to the inside of the two mounting holes. During the operation of the switch body 9, a large amount of heat is generated. At this time, the cooling fan 10 starts to run. The cooling fan 10 can effectively dissipate heat for the switch body 9, thereby effectively extending the service life of the switch body 9.

[0043] In order to effectively protect the switch body 9 from dust, the dustproof component includes a dustproof mesh cover 4 located above the closing cover 3. Both sides of the outer wall of the dustproof mesh cover 4 are fixedly connected to the mounting plate 7 through an L-shaped plate 6. The upper surface of the closing cover 3 is symmetrically provided with a fixing frame 5. The upper surfaces of the two fixing frames 5 are provided with guide grooves for the movement of the mounting plate 7. The interior of the mounting plate 7 is fixedly connected to a fixing block 16. The outside of the fixing block 16 is symmetrically provided with a telescopic rod 17. The telescopic ends of the multiple telescopic rods 17 are fixedly connected to the insertion rod 18. The outsides of the multiple telescopic rods 17 are all sleeved with connecting springs 19. The multiple connecting springs 19 are all in contact between the insertion rod 18 and the fixing block 16. The interior of the mounting plate 7 and the fixing frame 5 are provided with a guide groove for the movement of the insertion rod 18. When the switch body 9 needs to be protected from dust, it is only necessary to press the insertion rod first. 18. At this time, the insertion rod 18 will simultaneously squeeze the telescopic rod 17 and the connecting spring 19, and then the mounting plate 7 will be inserted into the interior of the fixed frame 5. At this time, the mounting plate 7 will drive the insertion rod 18 to move synchronously. When the mounting plate 7 drives the insertion rod 18 to move into the guide groove inside the fixed frame 5, the connecting spring 19 resets, driving the insertion rod 18 to move synchronously. When the insertion rod 18 is inserted into the guide groove inside the fixed frame 5, the mounting plate 7 and the fixed frame 5 can be fixed. At this time, the dustproof mesh cover 4 can be fixedly installed, so that the switch body 9 can be effectively protected from dust by the dustproof mesh cover 4, thereby further extending the service life of the switch body 9, and the staff can also conveniently disassemble, replace and clean the dustproof mesh cover 4, effectively improving the overall practicality of the device.

[0044] In addition, in order to provide dust-proof protection for the switch body 9 when the switch body 9 is not in use, a plurality of wire insertion holes 15 are opened through the front surface of the protective shell 1, and a plurality of connection frames 30 are fixedly connected to the front surface of the protective shell 1. The interior of the plurality of connection frames 30 is fixedly connected to a fixing rod 31, and the outside of the fixing rod 31 is fixedly connected to a spiral spring 32. The other end of the spiral spring 32 is fixedly connected to a rotating sleeve 33. The outside of the rotating sleeve 33 is fixedly connected to a rubber protective plug 36 through a side plate 34. The outside of the side plate 34 is fixedly connected to a paddle 35. When the switch body 9 needs to be plugged in for use, it is only necessary to paddle the paddle 35 first. At this time, the paddle 35 will drive the side plate 34 to move synchronously, and the side plate 34 will drive the rotating sleeve 33 to rotate synchronously, and the rotating sleeve 33 will then rotate the spiral spring 32 synchronously. When the switch body 9 is not needed, just pull out the wire head. At this time, the vortex spring 32 resets, driving the rotating sleeve 33 to rotate synchronously, and the rotating sleeve 33 drives the side plate 34 to move synchronously, and the side plate 34 drives the rubber protective plug 36 to move synchronously. When the rubber protective plug 36 is clamped to the wire plug hole 15 on the front surface of the protective shell 1, the protective shell 1 can be sealed by the rubber protective plug 36, thereby preventing dust and other impurities in the external environment from entering the interior of the protective shell 1 through the wire plug hole 15.
