Technical Field
[0001] This utility model relates to the field of switch technology, specifically to a switch external wiring protection device. Background Technology
[0002] A switch, meaning "switch," is a network device used for forwarding electrical (optical) signals. It can provide a dedicated electrical signal path for any two network nodes connected to the switch. The most common type of switch is the Ethernet switch, while other common types include fiber optic switches. In mining operations, mine cameras and positioning devices are required, so switches are needed to ensure that the mine cameras and positioning devices can transmit data normally.
[0003] The switch with public serial number CN218385935U has exhibited the following defects during use:
[0004] This utility model features multiple RS485 data connection ports, offering advantages such as long communication distance and support for multi-level network communication. Each RS485 data connection port supports parallel connection of multiple devices. Furthermore, an inverter is integrated into the switch body to convert the 220V voltage to the 12V voltage required by the positioning device and camera, enabling unified management of the data power lines. Wireless signal receiving antennas are located on both sides of the switch body for wireless signal reception, facilitating convenient operation and ensuring the normal and efficient use of the switch body. However, in actual use, the method of positioning the wiring using plugs and positioning blocks may lead to tangling and knotting at the interface front end when there are many wires. This can damage the wiring itself and affect the stability of the connection. Therefore, we propose an external wiring protection device for the switch. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a protective device for external wiring of a switch. It solves the problem that using plugs and positioning blocks to position wiring may result in knots and tangles at the front end of the interface when there are many wirings. This not only damages the wiring itself but also affects the stability of the connection.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0007] An external wiring protection device for a switch includes a base plate. A first placement groove is formed on the top surface of the base plate. A lower pressure plate is disposed inside the first placement groove. An upper pressure plate is disposed on the top surface of the lower pressure plate. Two through holes are formed on the top surface of the lower pressure plate. Two sliding rods are fixedly installed on the bottom surface of the upper pressure plate. A plurality of lower pressure holes are formed on one side of the lower pressure plate. A plurality of upper pressure holes are formed on one side of the upper pressure plate. The lower pressure holes and the upper pressure holes are positioned correspondingly and are complementary semi-circular structures.
[0008] Preferably, a limiting plate is fixedly installed at the bottom end of the sliding rod, the lower pressure plate and the upper pressure plate are snapped together by the sliding rod and the limiting plate, a spring is sleeved on the outer wall surface of the sliding rod, the spring is limited by the inner top surface of the through hole opened on the top surface of the limiting plate and the lower pressure plate, and a limiting ring is fixedly installed on the outer wall surface of the sliding rod.
[0009] Preferably, the first placement groove has snap-fit grooves on both sides, and the lower pressure plate has snap-fit blocks fixedly installed on both sides. The lower pressure plate is snapped into the interior of the first placement groove through the snap-fit grooves and the snap-fit blocks.
[0010] Preferably, the top surface of the base plate is provided with a fixing groove, and the switch body is fixedly installed inside the fixing groove. A number of connection holes are provided on one side of the switch body, and a protective pad is snapped into the inside of the connection hole. The protective pad is composed of a waist-shaped tube structure and a waist-shaped frame structure on the outer wall of both ends.
[0011] Preferably, two limiting blocks are provided on one side of the protective pad. The limiting blocks are arc-shaped. Two through holes are provided on one side of the protective pad. A through hole is opened on one side of the limiting blocks. The two through holes and the through hole on one side of the protective pad are aligned. A screw is sleeved inside the through hole. A nut is threaded onto the outer wall of the screw. The limiting blocks are engaged with one side of the protective pad by the screw and the nut.
[0012] Preferably, a pad is fixedly installed on the inner wall surface of the limiting block, and the pad is made of rubber.
[0013] In summary, the present invention has the following main advantages:
[0014] 1. By setting a lower pressure plate and an upper pressure plate, two sliding rods are set inside the through hole on the top surface of the lower pressure plate. On the one hand, the distance between the lower pressure plate and the upper pressure plate can be adjusted at any time. On the other hand, the sliding trajectory of the upper pressure plate is restricted, allowing the upper pressure plate to slide in a vertical direction. In use, the wire is placed between the lower pressure hole and the upper pressure hole. By moving the lower pressure plate and the upper pressure plate, the lower pressure hole and the upper pressure hole can be made to make close contact with the wire. This limits the wire before the interface is connected, avoiding the wire from getting tangled, causing them to pull against each other, and affecting the stability of the connection.
[0015] 2. By setting a limit block, the angle can be rotated freely when the nut is not tightened. When the wiring is placed inside the protective pad, it can make close contact with the wiring and provide auxiliary limit for the wiring. When adjusted to the position of close contact with the wiring, tightening the nut locks the limit block, ensuring that the limit function can be used normally. Through the design of the pad, the wear between the inner wall of the pad and the wiring can be reduced while ensuring the limit function of the limit block, avoiding wear and damage to the protective layer of the connecting wire.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] refer to Figures 1-4 An external wiring protection device for a switch includes a base plate 1. A first placement groove 2 is formed on the top surface of the base plate 1. A lower pressure plate 3 is disposed inside the first placement groove 2. An upper pressure plate 4 is disposed on the top surface of the lower pressure plate 3. Two through holes are formed on the top surface of the lower pressure plate 3. Two sliding rods 5 are fixedly installed on the bottom surface of the upper pressure plate 4. Several lower pressure holes 6 are formed on one side of the lower pressure plate 3, and several upper pressure holes 7 are formed on one side of the upper pressure plate 4. The lower pressure holes 6 and upper pressure holes 7 are positioned correspondingly and have complementary semi-circular structures. Through the design of the lower pressure plate 3 and upper pressure plate 4… Two sliding rods 5 are set inside the through holes on the top surface of the lower pressure plate 3. On the one hand, the distance between the lower pressure plate 3 and the upper pressure plate 4 can be adjusted at any time. On the other hand, the sliding trajectory of the upper pressure plate 4 can be restricted, allowing the upper pressure plate 4 to slide in a vertical direction. When in use, the wire is placed between the lower pressure hole 6 and the upper pressure hole 7. By moving the lower pressure plate 3 and the upper pressure plate 4, the lower pressure hole 6 and the upper pressure hole 7 can be made to make close contact with the wire. This limits the wire before the interface is connected, preventing the wire from getting tangled and pulling on each other, which would affect the stability of the connection.
[0023] A limiting plate 8 is fixedly installed at the bottom end of the sliding rod 5. The lower pressure plate 3 and the upper pressure plate 4 are connected together by the sliding rod 5 and the limiting plate 8. A spring 9 is sleeved on the outer wall of the sliding rod 5. The spring 9 is limited by the inner top surface of the through hole opened on the top surface of the limiting plate 8 and the lower pressure plate 3. Through the design of the spring 9, after the limiting ring 10 is released, the elastic force of the spring 9 can force the lower pressure plate 3 and the upper pressure plate 4 to return to the distance before pressing, which is convenient for the next limiting of the connecting line. A limiting ring 10 is fixedly installed on the outer wall of the sliding rod 5. Through the design of the limiting ring 10, the state of the lower pressure plate 3 and the upper pressure plate 4 after pressing can be restricted. When the lower pressure plate 3 and the upper pressure plate 4 are in the pressing state, the top surface of the limiting ring 10 and the bottom surface of the upper pressure plate 4 can be limited. The gaps on the surface limit the distance between the lower pressure plate 3 and the upper pressure plate 4, ensuring stable restriction of the connecting wires. The inner sides of the first placement slot 2 are provided with snap-fit slots 11, and the lower pressure plate 3 is fixedly installed with snap-fit blocks 12 on both sides. The lower pressure plate 3 is snapped into the interior of the first placement slot 2 through the snap-fit slots 11 and snap-fit blocks 12. The design of the snap-fit slots 11 and snap-fit blocks 12 allows them to act as a pivot, ensuring the stability of the lower pressure plate 3 within the first placement slot 2 while allowing it to rotate. When not in use, the lower pressure plate 3 can be rotated and stored inside the first placement slot 2, effectively reducing the space occupied by the device during storage. The top surface of the base plate 1 is provided with a fixing slot 13, inside which the switch body 14 is fixedly installed. The switch body 14 has several connection holes 15 on one side. Protective pads 16 are fitted inside the connection holes 15. The protective pads 16 consist of an oblong tube structure and oblong frame structures on both ends of the outer wall. The design of the protective pads 16 protects the inner wall of the connection holes 15 and the outer wall of the connecting wires, effectively reducing wear during plugging and unplugging and slowing down the wear and damage to the protective layer of the connecting wires. Two limiting blocks 17 are provided on one side of the protective pads 16. The limiting blocks 17 have an arc-shaped structure. Two through holes are provided on one side of the protective pads 16. A through hole 18 is provided on one side of the limiting blocks 17. The two through holes and the through hole 18 on one side of the protective pads 16 are aligned. A screw 19 is fitted inside the through hole 18, and the outer wall of the screw 19 is threaded. A nut 20 is attached, and a limiting block 17 is engaged with the nut 20 on one side of the protective pad 16 via a screw 19. The limiting block 17 is designed to rotate freely when the nut 20 is not tightened. When the wiring is placed inside the protective pad 16, it can make close contact with the wiring and provide auxiliary limiting for the wiring. When adjusted to a position that makes close contact with the wiring, tightening the nut 20 locks the limiting block 17, ensuring that the limiting function can be used normally. A pad 21 is fixedly installed on the inner wall of the limiting block 17. The pad 21 is made of rubber. The design of the pad 21 can reduce the wear between the inner wall of the pad 21 and the wiring while ensuring the limiting function of the limiting block 17, thus avoiding wear and damage to the protective layer of the connecting wire.
