Description

Technical Field

[0001] This invention relates to the field of power distribution equipment technology, specifically to a primary and secondary integrated ring network box. Background Technology

[0002] Ring main units (RMUs) are key equipment in power distribution systems, primarily used for power distribution, control, and protection. Typically, RMUs use a separation of primary and secondary equipment. Primary equipment mainly refers to load switches, circuit breakers, and other devices that perform power transmission, distribution, and switching functions, arranged in multiple bays to form the primary compartment of the RMU. Secondary equipment mainly refers to distribution terminals (DTUs), protection relays, and other devices that monitor, control, protect, and communicate with the primary equipment; these are usually installed in separate cabinets next to the primary compartment. However, this traditional separation of primary and secondary equipment still presents the following problems in practice.

[0003] For example, in practical applications, conventional anti-corrosion spraying and simple sealing are currently the main methods used, lacking a coordinated design from material coating and structural sealing to electromagnetic shielding. When encountering complex environments, such as high humidity and strong electromagnetic environments, primary and secondary components are prone to failure due to insufficient protection, resulting in a higher failure rate and a shorter service life. In addition, the lack of standard communication protocols and electrical interfaces between devices from different manufacturers makes system operation and maintenance difficult. Summary of the Invention

[0004] This invention provides a primary and secondary integrated ring network box, which uses a set of mechanically strongly coupled collaborative mechanisms to integrate the two into an organic whole. By providing the necessary operation of external electrical connection as a mechanical power source and trigger signal to drive the internal environment to strengthen control, and by using a set of precise mechanical linkage parts to forcibly lock the connection process after the purification environment is established, the risk of contamination introduced during operation and maintenance plugging and unplugging is eliminated at the source, and a clean and stable physical basis is provided for the adaptive electrical protocol.

Furthermore, it solves the hardware interface matching problem through a physical coded key and an anti-misinsertion mechanism. The time window provided by the purification process allows the system backend to automatically identify and adapt to different communication protocols, enabling plug-and-play functionality for equipment from different manufacturers. This significantly reduces the complexity and cost of system integration and modification. It deeply couples the two independent functions of environmental control and interface connection through a set of mechanically linked components, so that every necessary external connection operation automatically triggers a targeted environmental maintenance.

[0017] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the invention and to fully convey the scope of the invention to those skilled in the art.

[0018] like Figures 1 to 13 As shown, a primary and secondary integrated ring grate box includes: a base plate 1, multiple frames arranged above the base plate 1, side plates 2 arranged between adjacent front and rear frames, a cabinet door 4 arranged on the inner side of the frame above the base plate 1 in the horizontal direction, a top plate 6 fixedly installed on the top of the side plates 2, a baffle 3 fixedly installed on the top plate 6, a fully sealed partition 11 for primary and secondary partitioning arranged in the middle between the top plate 6 and the base plate 1, and central vertical plates 7 symmetrically fixedly installed on both sides of the fully sealed partition 11. The box is characterized by further including: The environmental control unit is located on one side of the central vertical plate 7 and is used to separate the layout of internal electronic components. The environmental control unit includes components and temperature-conducting components. The components are located on one side of the central vertical plate 7, and the components and temperature-conducting components are connected. The temperature-conducting components are located on the other side of the fully sealed partition 11. The interface connection part is located on the inside of one of the side plates 2 and is used to lock the ring network box; The interface connection part includes a connector and a wind control. The connector is disposed on the inner side of one of the side plates 2. The connector and the wind control are connected, and the wind control is disposed on one side of the connector.

[0019] The mechanical linkage is located on the inner wall of cabinet door 4, in front of the connecting parts, and is used for adjustment and processing. The mechanical linkage includes an intermediate connector and a heat dissipation component. The intermediate connector is located on the inner wall of cabinet door 4. The intermediate connector and the heat dissipation component are connected, and the heat dissipation component is located inside the intermediate connector.

[0020] Specifically, the fully sealed partition 11 can divide the internal space into a primary fusion area and a secondary fusion area, and can work with the top plate 6 to completely seal the secondary fusion area; an insulating base is provided behind the middle vertical plate 7 to support the installation of the bus coupler 13, facilitating current disconnection and control; there are multiple cabinet doors 4, and a sealing strip is provided between two adjacent cabinet doors 4 for auxiliary sealing to prevent dust from seeping in; the side plate 2 has a cavity inside, which can facilitate heat dissipation, etc. In practical applications, during the installation phase, the sealed front cabinet door 4 is first opened, and then various components, such as the busbar unit 8, load switch fuse 9, first current transformer 10, bus coupler 13, secondary integrated module 17, and second current transformer 18, are sequentially installed on the central vertical plate 7. After that, power is supplied for processing and use. The independent welded cabin is composed of the frame, bottom plate 1, top plate 6, side plate 2, fully sealed partition 11, and front operating cabinet door 4 with multiple sealing strips. It is divided into a primary equipment cabin and a secondary equipment core sealed cabin. The signal transmission through the wall bushing 25 introduces the side sensor signals, and then connects the external data with the dual-door intelligent airlock interface to facilitate the use of the overall equipment. When there is no external connection operation, it mainly operates autonomously through the integrated overall system. During use, the secondary fusion assembly area generates a certain amount of heat, which enters the sandwich main air duct 39 and the main air plate 40 through the inside of the side plate 2, and then is conducted to the interior of the condensation section fins 26 through the evaporation section substrate 23 on one side of the fully sealed partition 11 in the secondary fusion assembly area, forming a continuous silent heat dissipation cycle with no power consumption, ensuring the stable performance of the cabin.

[0021] like Figures 2 to 6 As shown, the components include: The busbar unit 8 and the intelligent switch 12 are located in front of the central vertical plate 7 and are used to adjust the internal lines and current. The load switch fuse 9 is installed on one side of the incoming / outgoing bus unit 8; The first current transformer 10 is installed on the primary side of the fully sealed partition 11. It safely converts the high voltage and large current on the primary side into the low voltage and small current on the secondary side, while achieving electrical isolation for measurement, protection and control. The bus coupler 13, which has multiple units, is located behind the central vertical plate 7. It is the core hub component of the primary equipment compartment and is the key to the flexible switching operation of the ring network power supply. The secondary integration module 17 is located on the outside of the middle vertical plate 7 and inside the secondary fusion area. It is used to integrate current, signal and other data together for easy control. The second current transformer 18 is located on the outside of the middle vertical plate 7 and inside the secondary fusion area. The temperature-conducting components include: The energizing tube 15 is located inside the side plate 2 and is used to process the current. A through hole is provided between the side plate 2 and the power supply pipe 15; The signal receiver 16 is located at one end of the energized tube 15; The evaporation section substrate 23 is disposed on the inner wall of the fully sealed partition 11; The conduction pipe 24 is located at the bottom end of the signal receiver 16 and passes through and connects to the fully sealed partition 11; The condenser section fins 26 are located on the outside of the conduction pipe 24; Two metal tweezers 28 are provided above and below the condenser section fins 26 to deform according to temperature in order to control the temperature. Specifically, the evaporation section substrate 23 is used to collect and transfer heat to ensure heat management within the equipment; the conduction pipe 24 is used to introduce signals to establish a connection between the primary and secondary fusion assembly areas; the condensation section fins 26 facilitate the neutralization of heat to ensure a clean environment inside the equipment; and the signal receiver 16 is used to convert heat signals and transmit them to the primary fusion assembly area via the conduction pipe 24. In practical applications, when the heat is high and the internal heat dissipation is slow, which may cause damage, the heat enters the interior of the side plate 2 and enters the interior of the signal receiver 16 through the power supply pipe 15. Finally, the heat balance of the condenser section fins 26 is achieved, ensuring the heat balance within the primary and secondary fusion assembly area and providing an automatic and silent heat handling function.

[0022] like Figures 6 to 9 As shown, the connector includes: The through-wall sleeve 25 is installed on one side of the fully sealed partition 11 and is used for signal transmission; Electrical connector 20 is fixedly installed at the top of the fully sealed partition 11 and located above the conductive conduit 24; The airlock chamber 32 is located in front of the electrical connector 20; The key restriction strip 30 is located inside the cabinet door 4 and in front of the purified airlock chamber 32; Wind control includes: The miniature sensor 27 is disposed on the inner wall of the fully sealed partition 11 and located on one side of the condenser section fin 26.

[0023] The damper 45 is installed through the inner side of the side panel 2 to allow airflow to enter. The interior of side panel 2 is hollow to reserve space for air ducts; The sandwich main air duct 39 is installed on the inner wall of the side panel 2; The main air panel 40 is located above the sandwich main air duct 39 and is used to cooperate with the sandwich main air duct 39.

[0024] Specifically, the through-wall sleeve 25 penetrates the fully sealed partition 11 and extends into the primary fusion assembly area, used to connect the signals in the primary fusion assembly area and the secondary fusion assembly area; the inner wall of the side panel 2 is provided with a desiccant to absorb moisture in the air duct; the purified airlock 32 and the key restraint strip 30 are easily matched with the key pin 21 to form a combination; the electrical connector 20 facilitates support for the purified airlock 32; the conduction pipe 24 is located in the front door panel for external data connection; the combination of the sandwich main air duct 39 and the main air plate 40 facilitates slow air exchange through the sandwich main air duct 39 in the side panel when there is a small pressure difference in the secondary fusion assembly area; the miniature sensor 27 is used to control the internal current temperature; the purified airlock 32 is used to connect the key pin 21 and the electrical connector 20; one end of the key pin 21 is provided with a raised and recessed physical code that is compatible with the elastic latch array at the entrance of the electrical connector 20; the miniature sensor 27 is used to sense internal moisture; In practical applications, when there is moisture inside the secondary fusion area and it needs to be treated, air enters the side plate 2 through the damper 45 and comes into contact with the sandwich main air duct 39. The wind blows the sandwich main air duct 39, and the main air plate 40 is affected by the sandwich main air duct 39 and moves. Through the wave action, the internal moisture is blocked, preventing the moisture from seeping out quickly. In the path formed by the tortuous main air plate 40 and sandwich main air duct 39, the dust in the air is blocked, and the water vapor is absorbed by the replaceable desiccant module in the middle of the air duct. This process is relatively slow, which is enough to balance the air pressure in the secondary fusion area, maintain low humidity, and prevent a large amount of air from rushing in from the outside. like Figures 3 to 10 As shown, the connector includes: The partition sleeve 41 is installed on the inner wall of the purified airlock chamber 32 and located on one side of the purified airlock chamber 32, and is used to limit the direction of insertion. Torsion plate 42 is hinged to one side of partition wall sleeve 41; Key pin 21 is located on one side of partition wall sleeve 41; The flexible rubber tube 22 is installed at the top of the partition wall sleeve 41; The inner side of the partition wall sleeve 41 is provided with a slot hole that matches the key pin 21, so that the partition wall sleeve 41 can be combined with the purified airlock chamber 32 through the slot hole.

[0025] The connector also includes: Positioning pin 37 is installed inside the purified airlock chamber 32; The retaining ring 38 is located on one side of the positioning pin 37; Multiple tension springs 43 are evenly arranged on one side of the torsion plate 42 and located at the outer edge of the soft rubber tube 22; The positioning knob 44 has a V-shape on one side, is located below one end of the torsion plate 42, and matches the retaining ring 38. Miniature air flap 50 is installed on the inner wall of the purified airlock chamber 32; The flexible duct 150 is installed below the purified airlock chamber 32 and passes through the power supply pipe 15 to connect with the bypass high-pressure air duct 47. Mechanical linkage components are installed inside the purified airlock chamber 32 to complete synchronous heat and moisture treatment during insertion. Mechanical linkage parts include: The first cam groove 210 is formed on the outside of the key pin 21; The first rotating shaft 212 is rotatably disposed inside the purified airlock chamber 32; The first follower roller 211 is fixedly installed on the outside of the first rotating shaft 212; The first swing arm 213 is fixedly installed on the outside of the first rotating shaft 212 and located on the outside of the first follower roller 211; The first short connecting rod 214 is located at one end of the first swing rod 213; The second rotary cam 215 is fixedly installed on the outside of the first rotary shaft 212 and located on the other side of the first follower roller 211; The central support shaft 217 is rotatably installed inside the purified airlock chamber 32; The second swing arm 216 is fixedly installed on the outside of the central support shaft 217.

[0026] Specifically, the partition sleeve 41 is used to support the torsion plate 42 and restrict the keyhole of the key pin 21; a rotating strip is provided between the partition sleeve 41 and the torsion plate 42; the purified airlock chamber 32 is located between the electrical connector 20 and the key pin 21, the physical code of the key pin 21 corresponds to a specific equipment protocol type, after insertion, the system can automatically identify and load the corresponding communication protocol driver to achieve plug and play; the key pin 21 is compatible with the partition sleeve 41; the electrical connector 20 is provided with a guide groove inside to guide heat.

[0027] In actual use, the physical coding of the mechanical coding key pin 21 at the end of the external device's cable moves along the inside of the key restriction strip 30 and toward the elastic locking tongue array on the electrical connector 20. Finally, it is inserted into the electrical connector 20 through the airlock chamber 32 to form a combination, thereby releasing the key and preventing hardware-level misinsertion. A reset spring is provided at the bottom of the elastic locking tongue on the electrical connector 20.

[0028] When the key pin 21 is inserted, the cam on it directly pushes a mechanical linkage part, which first opens the damper 45, allowing airflow to enter the bypass powerful air duct 47 for dehumidification; at the same time, this movement is recorded by another delay gear set, and after a preset mechanical delay to ensure the purification time, the locking of the elastic locking tongue inside the electrical connector 20 is released, allowing the key to continue to be inserted to complete the electrical connection. After the key pin 21 is inserted into the airlock chamber 32 and then further inserted, the soft rubber tube 22 on the outside of the key pin 21 contacts the inner wall of the airlock chamber 32 and squeezes the torsion plate 42, causing the torsion plate 42 to deflect. At this time, the tension spring 43 is pushed by the key pin 21 and extends, and the positioning torque 44 comes into contact with the retaining ring 38. The positioning torque 44 is temporarily locked on the retaining ring 38. Small magnets with opposite magnetic poles are provided on the contact surfaces of the two. After they come into contact, they are fixed, thus forming a locking effect. When moving back, when the key pin 21 is pulled back, the force of the soft rubber tube 22 against the tension spring 43 is released. The tension spring 43 contracts and pulls the positioning torque 44 back from the retaining ring 38, thus forming a retracting effect for the next use.

[0029] Meanwhile, during the process of linking input and power source, the side of the key pin 21 is provided with a first cam groove 210. When the key is inserted, the first cam groove 210 pushes a first follower roller 211 set in the purification airlock chamber 32 to work. In the first stage of the action, the first follower roller 211 is fixed on the first rotating shaft 212, and a first rocker arm 213 is also fixed on the first rotating shaft 212. When the key is inserted, the first cam groove 210 pushes the follower roller, the first rotating shaft 212 rotates, and drives the first rocker arm 213 to swing. The end of the first rocker arm 213 is connected to the bottom wall of the miniature damper 50 through a first short connecting rod 214. That is, the key insertion motion is converted into the opening motion of the miniature damper 50. The second-level action, state transmission and delayed triggering, involves a second rotating cam 215 coaxially fixed on the first rotating shaft 212. The contour of the second rotating cam 215 and the contour of the first cam groove 210 are designed to match the phase difference. When the first rotating shaft 212 rotates to the position where the damper 50 reaches the predetermined opening degree due to the key insertion, the second rotating cam 215 rotates exactly to the high point area of ​​its contour. The final action unlocks the elastic latch on the electrical connector 20. The high point of the second rotating cam 215 pushes one end of a second lever 216. The middle of the second lever 216 is hinged to the frame of the purified airlock 32, forming a lever. The other end of the second lever 216 is connected to the return spring of the elastic latch on the electrical connector 20. When the second rotating cam 215 pushes the second lever 216, the lever action overcomes the force of the first rotating shaft 212 of the latch, pulling the elastic latch out of the lock hole of the electrical connector 20, thereby unlocking. Therefore, only when the key is inserted deep enough to trigger the air damper to open, and the first rotating shaft 212 rotates to a specific position, indicating that the miniature air damper 50 is working, will the second rotating cam 215 move to a position that can push open the elastic latch. Any attempt to bypass the miniature air damper 50 and directly unlock the door will be impossible due to the physical obstruction of the cam profile.

[0030] like Figures 7 to 13 As shown, the heat sink includes: The rotating shaft 35 is located on one side of the purified airlock chamber 32; Fan blade 36 is located on the outside of the rotating shaft 35; Pressure sensor 34 is located at one end of rotating shaft 35; The labyrinthine main air duct 46 is installed on the inner wall of the side panel 2; A bypass high-power air duct 47 is located on the other side of the labyrinthine main air duct 46; Temperature sensor 48 is located on one side of bypass high-power air duct 47; A partition plate 49 is installed between the labyrinthine main air duct 46 and the bypass powerful air duct 47 on the inner wall of the side plate 2.

[0031] Specifically, a servo motor is installed at one end of the rotating shaft 35 and connected to the output end of the servo motor, and a processor is installed at the other end; a pressure sensor 34 is used to contact the torsion plate 42 to sense changes in position and facilitate signal output to the processor; a labyrinthine main air duct 46 and a bypass high-power air duct 47 are located below the side plate 2; a support shaft is installed between the partition plate 49 and the side plate 2 to allow the partition plate 49 to rotate; a miniature cyclone separator is installed inside the bypass high-power air duct 47, with a small top and a large bottom opening, for moisture isolation treatment of the equipment.

[0032] In practical application, the key pin 21 is inserted into the interior of the partition sleeve 41 and pushes the torsion plate 42 and the positioning knob 44 to rotate together. When the positioning knob 44 rotates, it contacts the pressure sensor 34. The pressure sensor 34 transmits the signal to the processor. The processor drives the motor to work and drives the fan blade 36 to rotate through the rotating shaft 35. The airflow is introduced into the primary fusion sleeve area through the electrical connector 20 and passes through the condenser section fins 26 to balance the heat and ensure a reasonable internal environment. The equipment enters the side plate 2 through the damper 45 and then enters the sandwich main air duct 39 through the labyrinthine main air duct 46, where it comes into contact with the main air plate 40. The heat is then conducted away through the signal receiver 16 and the conduction pipe 24, and the heat is balanced through the evaporation section substrate 23 and the condensation section fins 26. When the humidity is high, the moisture will enter the side plate 2 through the damper 45. At this time, the temperature sensing block 48 drives the electric telescopic rod to pull the partition plate 49 back. The top of the partition plate 49 blocks the labyrinthine main air duct 46, and the moisture is introduced into the bypass strong air duct 47. After being processed by the micro cyclone separator, the moisture that rises is negligible, thus completing the use of the equipment. A control method for a primary and secondary integrated ring network enclosure, applied to a primary and secondary integrated ring network enclosure, includes the following steps: Insert the key pin 21 with the physical code into the key restriction strip 30 of the ring network box; The insertion action of the key pin 21 is converted into the rotation of the first rotating shaft 212 through the mechanical linkage parts; The rotation of the first rotating shaft 212 first drives the air damper 45 or the miniature air plate 50 of the environmental control unit to open, thus purifying the connecting channel; After the first rotating shaft 212 rotates to the predetermined position, the second rotating cam 215 fixed thereon drives the lever mechanism to release the lock of the electrical connector. During the purification phase, the system identifies the external device protocol based on the physical code of the key pin 21 and completes the protocol adaptation.

[0033] Working principle: It can be mainly divided into two modes: autonomous operation under normal conditions and external connection triggering. Its essence lies in the fact that, through a set of precise mechanical linkage parts, the necessary connection operation to external devices is forcibly transformed into an irreversible process of first performing environmental purification and then establishing electrical connection, thereby preventing pollution intrusion at the physical level and providing a guarantee for intelligent adaptation.

[0034] Part 1: Under normal conditions, the ring network box operates independently when no external connection is required. When no external device connection is needed, the system is in a low-power silent maintenance state, and its core tasks are heat dissipation management and microenvironment maintenance. Heat generation and collection: The main heat is generated by the operation of equipment such as the inlet and outlet busbar unit 8, intelligent switch 12, and bus coupler 13 in the primary equipment compartment, and the secondary integrated module 17 in the secondary equipment compartment will also generate a certain amount of heat; the evaporation section substrate 23 located on the side of the secondary compartment and close to the fully sealed partition 11 continuously absorbs the heat of the air in the compartment. During the process of the heat pipe in silent heat dissipation without power consumption, the low-boiling-point working fluid in the evaporation section substrate 23 is heated and evaporated. The vapor is transported through the conduction pipe 24 to the heat pipe's adiabatic transmission section to the condensation section fin 26 located at the heat pipe's condensation end on the primary equipment compartment side. Steam is cooled at the condenser fins 26, and condenses into liquid in the relatively large space of the primary compartment through natural convection, releasing latent heat of vaporization. At this time, the heat is dissipated into the air of the primary compartment through the fins. The condensed liquid working fluid flows back to the evaporator substrate 23 along the tube wall under the action of gravity or capillary force, completing a closed-loop heat dissipation cycle that does not require a fan or pump. This process continues to maintain the temperature balance of the secondary core sealed compartment. During the process of balancing micro-pressure and humidity, the secondary compartment is not absolutely airtight, allowing extremely slow gas exchange to balance the pressure. When a slight pressure difference exists between the inside and outside, air is exchanged through the sandwich-type main air duct 39 and the labyrinthine main air duct 46 inside the side panel 2. These air ducts are designed to be winding and long, and their inner walls are coated with desiccant. As air slowly passes through the duct, dust particles are blocked and moisture is absorbed by the desiccant, achieving the effect of breathing without inhaling moisture and dust. The metal fin 28 senses the temperature of the condenser section fin 26. If the temperature is too low, condensation may occur. Its deformation can be linked to the fine adjustment of the air duct to prevent condensation. In the second scenario, the external connection trigger mode, when the key pin 21 is inserted, the maintenance personnel need to perform data connection or debugging. When the key pin 21 at the end of the external device cable is inserted into the key restriction strip 30 on the cabinet door 4, a forced chain reaction is triggered, and the entire process is mechanically locked in sequence and cannot be skipped. Step 1: Physical code recognition and insertion start: The key pin 21 housing has a unique embossed physical code, which uniquely matches the shape of the key restriction strip 30 and the inlet of the airlock chamber 32, realizing hardware-level anti-misinsertion, and the insertion action begins; Step 2: Mechanical linkage triggers the first stage of action, opening the purification air duct: During the insertion process, the first cam groove 210 on the side of the key pin 21 pushes the first follower roller 211; the first follower roller 211 is fixed on the first rotating shaft 212, driving the first rotating shaft 212 to rotate, and the first swing rod 213 fixed on the same shaft swings accordingly; the first swing rod 213 pulls the miniature air plate 50 located on the bottom side of the purification airlock chamber 32 through the first short connecting rod 214 to open. At this time, the purification channel has been opened, but the electrical connector 20 is still in the mechanically locked state.

[0035] Step 3: During the execution of the forced purification process, as the key continues to be inserted, the opened miniature air panel 50 and air door 45 allow airflow to enter; The airflow is directed to the bypass high-power air duct 47 via a flexible duct. This air duct may be equipped with a miniature cyclone separator or a high-efficiency desiccant module. The high-speed airflow blows, dries and cleans the socket area of ​​the electrical connector 20 that is about to be connected, removing any dust and moisture that may be present. Meanwhile, the system's backend circuit identifies the protocol of the external device through the physical code of the key pin 21, and automatically loads the corresponding communication protocol driver within the few seconds of the purification process. Step 4: If a delay occurs during mechanical use, the electrical connection will be unlocked. Simultaneously with the rotation of the first rotating shaft 212, the second rotating cam 215 fixed to it also rotates. Its cam profile has a carefully designed phase difference with the first cam groove 210. When the key is inserted to a certain depth, that is, the purification has lasted for a preset mechanical delay time, such as seconds, the first rotating shaft 212 rotates to a specific angle, at which point the second rotating cam 215 just rotates to its highest point; The high point of the second rotary cam 215 pushes one end of the second rocker arm 216; The second lever 216 acts as a lever, and its other end pulls the reset mechanism of the elastic locking tongue inside the electrical connector 20 to release the locking of the socket of the electrical connector 20. Only at this point can the tip of the key pin 21 continue to advance and make contact with the electrical contacts of the electrical connector 20; Step 5: Establish complete connection and maintain state: When the key pin 21 is fully inserted, a stable electrical and communication connection is established with the electrical connector 20. The soft rubber tube 22 on the key pin 21 squeezes the torsion plate 42, causing the positioning torque 44 to engage with the retaining ring 38 under the action of the tension spring 43, forming a temporary mechanical lock to prevent the key from accidentally falling off. The purified airflow may switch to a low-speed maintenance mode to continue providing positive pressure clean air curtain to the working connection port. If the temperature inside the chamber rises during the connection, the pressure sensor 34 of the heat sink will sense the pressure of the positioning torque 44 and can start the fan blades 36 to enhance heat dissipation. When the temperature sensing block 48 senses that the humidity exceeds the standard, it will control the partition plate 49 to switch the air duct and introduce all the humid air into the bypass powerful air duct 47 for treatment. During the reverse linkage process of pulling out, a slight force is applied to twist and pull back the key pin 21, overcoming the magnetic force between the positioning torque 44 and the retaining ring 38, causing the tension spring 43 to contract and the positioning torque 44 to disengage; when the key pin 21 retracts, the mechanical linkage parts move in the opposite direction, the second rotating cam 215 disengages first, and the electrical connector 20 is immediately relocked by the spring; as the key continues to pull back, the first cam groove 210 causes the first rotating shaft 212 to reverse, and the miniature air vane 50 and the connected damper 45 close finally, cutting off the purified airflow; when the key is completely pulled out, the system returns to the autonomous operation mode under normal conditions, the purified airlock chamber 32 closes, and prevents outside air from entering.
