DETAILED DESCRIPTION

[0020] The following is a further detailed description of the embodiments of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the technical solutions of the present invention, but cannot be used to limit the protection scope of the present invention.

[0021] Embodiment 1: like Figures 1 to 12As shown, the present invention provides a switch capable of quick plug-in connection, including a switch body 11 and multiple groups of connecting wires 21, multiple groups of connecting ports 12 are arranged on the switch body 11, and a locking assembly is arranged on one side thereof, the locking assembly includes a locking shell 301, a wire tube 302 is arranged corresponding to the connecting port 12, and a connector 22 is arranged at one end of the connecting wire 21. During the connection process, the connector 22 will pass through the wire tube 302 and then be clamped in the connecting port 12, thereby achieving a stable and effective connection. A first protective shell 401 and a second protective shell 402 are arranged at the top and bottom of the switch body 11, respectively. Both protective shells are connected to the switch body 11 to form a protective cavity together. The protective cavity provides additional protection for the key components inside the switch body 11, so that it can operate in a relatively stable and safe environment. A ventilation duct 403 is arranged between the first protective shell 401 and the second protective shell 402, and the ventilation duct 403 connects the two groups of protective cavities, promotes the circulation of air in the entire system, and facilitates a more comprehensive heat dissipation on the surface of the switch body 11. At the same time, the heat dissipation component disposed inside the second protective shell 402 provides support for the stable operation of the entire system. When the switch body 11 is running at high load, a large amount of heat generated can be effectively dissipated through the heat dissipation component. Both sides of the first protective shell 401 are provided with first ventilation slots 404, so that hot air can be discharged smoothly. The entire switch body 11 can maintain good temperature control during operation, thereby improving the reliability and stability of the equipment and extending its service life.

[0022] like Figure 3 , Figure 5 , Figure 6 As shown, the locking housing 301 is connected to the switch body 11 by multiple sets of screws, ensuring that the locking housing 301 can be stably fixed on the switch body 11 during long-term use, providing reliable support and protection for the internal connection structure. Multiple sets of baffles 303 are arranged inside the locking housing 301. When the locking housing 301 is connected to the locking cover plate 304, the baffles 303 divide the internal space into multiple sets of locking cavities. The wire tube 302 is located in these locking cavities, providing a channel for the insertion and fixation of the connecting wire 21. The locking cover plate 304 is provided with a wire groove 305 corresponding to the wire tube 302. When the connection operation is performed, the connecting wire 21 can be inserted into the wire groove 305 and the wire tube 302. At the same time, in order to further enhance the sealing and stability, a sealing plate 23 is also arranged on one side of the locking cover plate 304. The sealing plate 23 is sleeved on the connecting line 21 and is in close contact with the locking cover plate 304, effectively preventing external impurities such as dust and water vapor from entering the locking cavity, thereby ensuring the reliability and stability of the connection.

[0023] The locking assembly also includes multiple sets of locking members 306 and multiple sets of first permanent magnets 307. The locking members 306 and the first permanent magnets 307 are both located in the locking cavity. Multiple sets of fixed blocks 308 are arranged inside the locking housing 301. The fixed blocks 308 are provided with fixed grooves 309. The locking members 306 are clamped in the fixed grooves 309 and can be smoothly slidably connected with the fixed blocks 308. The locking members 306 can be flexibly moved when needed to achieve the locking or loosening operation of the connecting line 21. In addition, multiple sets of limit blocks 310 are also arranged inside the locking housing 301. The first permanent magnet 307 is clamped between two sets of limit blocks 310 to ensure that its position is stable and can play an effective role. Multiple sets of protrusions 311 are arranged on one side of the locking cover plate 304. These protrusions 311 are respectively in contact with the fixed blocks 308 and the limit blocks 310, further enhancing the stability and reliability of the entire locking structure.

[0024] A locking block 24 is provided on the connecting line 21, and the locking block 24 is also inserted into the wire tube 302. Two groups of second permanent magnets 312 are provided in the fixing groove 309, and the locking member 306 is in contact with both groups of second permanent magnets 312. In addition, the magnetic strength of the first permanent magnet 307 is greater than that of the two groups of second permanent magnets 312. A locking groove 25 is provided on the locking block 24, and when a locking operation is required, the locking member 306 can pass through the wire tube 302 and be clamped in the locking groove 25 to achieve a firm locking of the connecting line 21. Not only does it ensure the stability of the connection, but it also provides convenience for quick plug-in and pull-out operations, greatly improving the efficiency and convenience of use.

[0025] A magnetic shielding plate 315 is provided in the locking cavity, and is located between the limiting block 310 and the fixing block 308 , which can effectively weaken the suction force of the first permanent magnet 307 on the locking piece 306 , so that the locking piece 306 is attracted by the second permanent magnet 312 and is clamped in the locking groove 25 . When it is necessary to plug in the connecting line 21, the magnetic shielding plate 315 is removed, the magnetic force of the first permanent magnet 307 is greater than the two groups of second permanent magnets 312, the locking piece 306 moves toward the first permanent magnet 307, retracts into the fixed groove 309, and the connector 22 is inserted into the connecting port 12. The magnetic shielding plate 315 returns to its original position, the magnetic force of the first permanent magnet 307 is weakened, and is less than the magnetic force of the two groups of second permanent magnets 312. The locking piece 306 moves toward the second permanent magnet 312, and the locking piece 306 is stuck in the locking groove 25; when it is necessary to unplug the connecting line 21, it is only necessary to move the magnetic shielding plate 315 so that the magnetic force of the first permanent magnet 307 is greater than the two groups of second permanent magnets 312, and the locking piece 306 withdraws from the locking groove 25, so that the connecting line 21 can be quickly unplugged. Through the locking assembly, users no longer need to face complicated screw removal and large clamping force, and can connect and remove the connecting line 21 with simple operations, saving time and labor costs and improving work efficiency.

[0026] In order to ensure the stable installation and flexible movement of the magnetic shielding plate 315, multiple groups of connecting rods 316 are arranged in the locking housing 301, and connecting rings 317 are provided on both sides of the magnetic shielding plate 315. The connecting rings 317 are sleeved on the connecting rods 316, and the magnetic shielding plate 315 and the connecting rods 316 are slidably connected. One end of the magnetic shielding plate 315 also passes through the locking cover 304, so that the magnetic shielding plate 315 can be easily controlled and adjusted during operation. Two groups of second springs are also arranged in the locking cavity, both of which are sleeved on the connecting rods 316, and their two ends are respectively in contact with the connecting rings 317 and the locking cover 304. The second spring gives the magnetic shielding plate 315 a certain elastic recovery ability. By compressing the second spring, the movement of the magnetic shielding plate 315 is achieved. When the magnetic shielding plate 315 is released, the magnetic shielding plate 315 returns to its original position due to the elasticity of the second spring. This not only improves the stability and reliability of the entire locking cavity structure, but also makes the operation of the magnetic shielding plate 315 more flexible.

[0027] like Figure 2 , Figure 7 , Fig.12 As shown, the heat dissipation assembly includes two groups of first fans 405 and two groups of semiconductor components 406, which provide a guarantee for efficient heat dissipation of the switch. Two groups of assembly slots 407 are provided at one end of the second protective shell 402, and one group of protective cavities is connected to the outside world through the two groups of assembly slots 407. The first fan 405 is clamped in the assembly slot 407, and a firm connection is achieved through the fixing screws, which not only ensures the stability of the first fan 405 during operation, but also facilitates subsequent maintenance and replacement. The first fan 405 can blow the outside air into the protective cavity, and the internal air is discharged through the first ventilation slot 404, so as to achieve heat dissipation operation for the switch body 11. Two groups of mounting frames 408 are also provided on the second protective shell 402, and the semiconductor components 406 are clamped on the top of the mounting frames 408 to achieve stable installation and effective heat dissipation. An assembly plate 409 is provided at the bottom of the mounting frame 408, and a second fan 410 is installed on the assembly plate 409. The semiconductor component 406 is used to realize the cooling effect, which can effectively reduce the temperature in the protective cavity, and the first fan 405 circulates the cold air to achieve a more comprehensive heat dissipation and cooling effect on the switch body 11, so that it can adapt to the needs of high-load operation, extend the service life of the switch, reduce failures and performance degradation caused by overheating, and improve the reliability and stability of the equipment. At the same time, the semiconductor component 406 will generate heat when in use, and the heat dissipation operation of the semiconductor component 406 is realized by the second fan 410. A second ventilation slot 411 is also provided on one side of the mounting frame 408, which can discharge the heat generated by the semiconductor component 406, ensuring the stable operation of the semiconductor component 406.

[0028] The heat dissipation component also includes a controller 412 and a temperature sensor 413, which realizes intelligent heat dissipation control. An installation box 414 is arranged inside the second protective shell 402, and an installation cover 415 is arranged on the opening surface of the installation box 414. The installation cover 415 is connected to the installation box 414, thereby forming a relatively closed installation cavity. The controller 412 is installed in this installation cavity and is effectively protected. The controller 412 can adopt an Omron CP1H controller. The temperature sensor 413 is located in the protective cavity and is installed on the second protective shell 402. The controller 412 and the temperature sensor 413 are effectively connected through a connecting wire. In this way, the temperature sensor 413 can sense the temperature change in the protective cavity in real time and transmit the data to the controller 412. The temperature sensor 413 can adopt a DS18B20 temperature sensor.

[0029] An adapter 416 is also provided in the installation cavity. The adapter 416 is electrically connected to the controller 412 and the external power supply, respectively, to provide stable power support for the entire heat dissipation assembly. Multiple sets of through slots are provided on both sides of the installation box 414 to ensure that the electronic components in the installation cavity maintain a certain heat exchange with the environment in the protective cavity to avoid local overheating.

[0030] like Figure 2 , Figures 9 to 11 As shown, multiple groups of adjusting screw rods 13 are respectively arranged at both ends of the switch body 11, and multiple groups of connecting members 14 are configured on the switch body 11. The adjusting screw rod 13 is inserted into the connecting member 14, so that the adjusting screw rod 13 and the switch body 11 can be slidably connected, which is convenient for subsequent position adjustment. Mounting seats 15 are respectively arranged at both ends of the adjusting screw rod 13, which provide a stable support and installation foundation for the entire structure. Multiple groups of connecting plates 16 are also arranged at both ends of the adjusting screw rod 13, and the connecting block 17 arranged on the mounting seat 15 is clamped between the two groups of connecting plates 16 and connected by a connecting bolt. Not only the stability of the structure is guaranteed, but also the mounting seat 15 and the adjusting screw rod 13 can be rotatably connected. In the actual installation and use process, the angle and position of the switch body 11 can be flexibly adjusted according to different installation environments and requirements, so as to better adapt to various complex installation scenarios. Two groups of regulating valves 18 are also sleeved on the adjusting screw rod 13. The connecting piece 14 is located between the two sets of regulating valves 18, and the regulating valves 18 are in contact with the connecting piece 14. When the position of the switch body 11 needs to be fixed, the regulating valve 18 is rotated to make it tightly against the connecting piece 14, thereby locking the position of the switch body 11. This brings convenience to the installation and use of the switch. Whether it is installed on an uneven surface or the position and angle of the switch needs to be adjusted according to specific space requirements, it can be achieved by adjusting the coordinated action of the screw rod 13, the regulating valve 18 and related connecting parts.

[0031] Embodiment 2: Based on the switch that can be quickly plugged and connected provided in the first embodiment of the present application, the second embodiment of the present application proposes a switch that can be quickly plugged and connected. This second embodiment is only a preferred method of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment. The second embodiment of the present invention will be further described below.

[0032] like Figure 4 , Figure 6 As shown, a locking block 24 is provided on the connecting line 21, and the locking block 24 is also inserted into the wire tube 302. Two groups of second permanent magnets 312 are provided in the fixing groove 309, and the locking member 306 is in contact with both groups of second permanent magnets 312. In addition, the magnetic strength of the first permanent magnet 307 is greater than that of the two groups of second permanent magnets 312. A locking groove 25 is provided on the locking block 24, and when a locking operation is required, the locking member 306 can pass through the wire tube 302 and be clamped in the locking groove 25 to achieve a firm locking of the connecting line 21. Not only does it ensure the stability of the connection, but it also provides convenience for quick plug-in and pull-out operations, greatly improving the efficiency and convenience of use.

[0033] In order to further enhance the stability and accuracy of the connection, locking sleeves 313 are also provided on both sides of the wire tube 302. A positioning ball 314 is provided in the locking sleeve 313, and the positioning ball 314 and the locking sleeve 313 are connected by a first spring. When the locking block 24 penetrates the wire tube 302, the positioning ball 314 will shrink inward due to the elastic effect of the first spring. When the positioning holes 26 on both sides of the locking block 24 correspond to the positions of the positioning balls 314, the positioning balls 314 will be stuck in the positioning holes 26 under the elastic force of the first spring. Not only does it provide additional positioning and fixing functions for the connection, but it can also effectively prevent the locking block 24 from shaking or displacing unnecessarily in the wire tube 302. Even in the case of external vibration or pulling, the cooperation between the positioning ball 314 and the positioning hole 26 can ensure the stability and reliability of the connection. The connection between the connecting line 21 and the switch is made more firm and stable, reducing the signal transmission problems that may be caused by loose connection. Whether it is in frequent plugging and unplugging or in a long-term stable connection state, it can provide guarantee for the normal operation of the equipment.

[0034] The difference between the second embodiment and the first embodiment is that locking sleeves 313 are also provided on both sides of the wire tube 302, and positioning balls 314 and first springs are provided in the locking sleeves 313. The synergistic effect of the positioning balls 314 and the first spring can provide additional positioning and fixing effects for the entire connection structure. When the connecting wire 21 is inserted, the first spring pushes the positioning balls 314 into the corresponding position, thereby enhancing the accuracy and stability of the connection. This effectively reduces the possible loose connection and displacement problems, and further improves the reliability of the connection. Even in a complex and changeable use environment, or subject to large external interference, the connection can be firmly connected to ensure the normal operation of the equipment. The remaining conditions are consistent with those of the first embodiment, so this embodiment will not be repeated.

[0035] The basic principles and main features of the present invention and the advantages of the present invention are shown and described above. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments.
