[0002] Electromagnetic shielding equipment is commonly used in testing scenarios for electronic and communication products to isolate external electromagnetic interference and ensure the accuracy of test results. Common electromagnetic shielding equipment includes shielding boxes and cabinets, which typically require control buttons, circuit control boards, solenoid valves, cylinders, and air pipelines to achieve opening, closing, or clamping actions.

[0003] Existing shielded enclosure control components are typically installed separately inside the equipment, resulting in numerous wire and air pipe connections. When control circuit boards, solenoid valves, or other control components malfunction, maintenance personnel need to disconnect wires and air pipes on-site and troubleshoot one by one, making the repair process complex and time-consuming.

[0004] For shielded enclosures used in production lines, equipment downtime for maintenance can impact production efficiency and increase maintenance costs. Especially when replacing control components, the existing structure hinders quick disassembly and assembly, easily leading to wiring errors, air leaks, or repeated debugging.

A central control box module is detachably mounted on the central control box, and the central control box module is provided with a second electrical connection structure and a second pneumatic connection structure; When the central control box module is installed to the preset installation position of the central control box using a preset installation method, the second electrical connection structure is plugged into the first electrical connection structure to form a transmission path for power signals, control signals, and / or feedback signals between the central control box module and the electromagnetic shielding device; at the same time, the second pneumatic connection structure is plugged into the first pneumatic connection structure to form a gas transmission path between the central control box module and the pneumatic actuator.

[0007] A second aspect of the present invention provides an electromagnetic shielding device, comprising a device body, a pneumatic actuator, and a central control device as described in the first aspect; the device body has an electromagnetic shielding space, the pneumatic actuator is used to drive the device body to open, close, and / or press, the central control device is installed on the device body, and a first pneumatic connection structure in the central control device is connected to the pneumatic actuator, and a first electrical connection structure in the central control device is electrically connected to a control component on the device body.

[0008] The present invention relates to a central control device and equipment for electromagnetic shielding equipment. By incorporating a first electrical connection structure and a first pneumatic connection structure within a central control box, and correspondingly incorporating a second electrical connection structure and a second pneumatic connection structure on a detachable central control box module, the central control box module can simultaneously achieve rapid plug-and-play connection of the electrical and pneumatic circuits when installed in a preset position, and simultaneously achieve rapid disconnection of the electrical and pneumatic circuits when removed. Therefore, when control components such as the control drive board and solenoid valves of the electromagnetic shielding equipment malfunction, maintenance personnel do not need to disconnect and reconnect wires and pipes individually on-site, nor do they need to spend a long time troubleshooting the wiring and pneumatic circuits.

Any technical solution described by the above terms in the embodiments of this application should not be construed as being more preferred or advantageous than other technical solutions. Specifically, these terms are intended to present the relevant technical concepts in terms of specific implementation methods.

[0017] To address the technical problems mentioned in the background section regarding the inconvenience of maintaining, complexity of disassembly and assembly, and long repair time of the control components of electromagnetic shielding equipment, please refer to [link to background section]. Figures 1 to 9 This application provides a central control device for use in an electromagnetic shielding device 100. The central control device mainly includes a central control box 200 and a central control box module 300. The details of each part are described below: The central control box 200, as an internal control component, is installed within the electromagnetic shielding device 100. The central control box 200 is provided with a first electrical connection structure 15 and a first pneumatic connection structure 16. The first electrical connection structure 15 is used for electrical connection with control components such as control buttons and detection components on the electromagnetic shielding device 100; the first pneumatic connection structure 16 is used for pneumatic connection with the pneumatic actuator on the electromagnetic shielding device 100.

[0018] The central control box module 300 is a detachable part, detachably mounted on the central control box 200. The central control box module 300 is provided with a second electrical connection structure 12 and a second pneumatic connection structure 11. The second electrical connection structure 12 is used for electrical connection with the first electrical connection structure 15, and the second pneumatic connection structure 11 is used for pneumatic connection with the first pneumatic connection structure 16.

[0019] When the central control box module 300 is installed in the preset installation position of the central control box 200 using a preset installation method, the second electrical connection structure 12 and the first electrical connection structure 15 are plugged into each other, forming a transmission path for power signals, control signals, and / or feedback signals between the central control box module 300 and the electromagnetic shielding device 100. Simultaneously, the second pneumatic connection structure 11 and the first pneumatic connection structure 16 are plugged into each other, forming a gas transmission path between the central control box module 300 and the pneumatic actuator.

[0020] It should be noted that the power signal can be a voltage / current signal supplying power to the central control box module 300, control drive board 3, solenoid valve module 10, control button 21, or other electrical components. For example, external power enters the central control box module 300 through the power aviation connector 8, and is then distributed to relevant electrical components via the control drive board 3. The control signal can be an electrical signal used to control the electromagnetic shielding equipment 100 to perform actions. For example, when an operator presses control button 21, control button 21 generates an open or close signal. This signal is transmitted to the control drive board 3 through the first electrical connection structure 15 and the second electrical connection structure 12. The control drive board 3 then controls the solenoid valve module 10 to operate, thereby driving the cylinder 22 to open or close the shielding box. The feedback signal can be a signal from the detection components on the electromagnetic shielding equipment 100 to the control drive board 3 to report the equipment status. Examples include open-box position signal, close-box position signal, air pressure detection signal, door position detection signal, and safety protection signal. The control drive board 3 can determine whether the equipment is operating normally based on these feedback signals.

[0021] When the central control box module 300 is removed from the central control box 200 in the preset removal method, the second electrical connection structure 12 is disconnected from the first electrical connection structure 15, and the second air circuit connection structure 11 is disconnected from the first air circuit connection structure 16, so as to realize the disassembly and assembly of the central control box module 300 relative to the electromagnetic shielding device 100.

[0022] During use, the central control box module 300 can control the opening, closing, or clamping action of the electromagnetic shielding device 100. When the control drive board, solenoid valve module, or other control components within the central control box module 300 malfunction, the operator can remove the central control box module 300 from the central control box 200, disconnecting the first electrical connection structure 15 from the second electrical connection structure 12, and simultaneously disconnecting the first pneumatic connection structure 16 from the second pneumatic connection structure 11. Then, a new central control box module 300 can be pushed into the central control box 200 to reconnect the circuits and pneumatic circuits.

[0023] It should be understood that the installation and removal methods can be set according to the specific structure of the central control box 200 and the central control box module 300. The installation method includes, but is not limited to, pushing, sliding, or inserting the central control box module 300 into the central control box 200 in a preset direction so that the central control box module 300 reaches the preset installation position; the removal method includes, but is not limited to, pulling, sliding, or removing the central control box module 300 from the central control box 200 in a direction opposite to the installation direction.

[0024] As can be seen, the central control device for electromagnetic shielding equipment in this application embodiment, by setting a first electrical connection structure and a first pneumatic connection structure inside the central control box, and correspondingly setting a second electrical connection structure and a second pneumatic connection structure on the detachable central control box module, allows for rapid plug-in connection of the circuit and pneumatic circuit when the central control box module is installed in a preset position, and rapid disconnection of the circuit and pneumatic circuit when it is removed. Therefore, when control components such as the control drive board and solenoid valves of the electromagnetic shielding equipment malfunction, maintenance personnel do not need to disconnect and reconnect wires and pipes one by one on-site, nor do they need to spend a long time troubleshooting the wiring and pneumatic circuits. The equipment can be restored to use simply by removing and replacing the entire central control box module. This simplifies maintenance operations, reduces the risk of wiring errors and pneumatic leaks, shortens equipment downtime, reduces maintenance costs, and improves production efficiency without affecting the normal control and shielding use of the electromagnetic shielding equipment.

[0025] Please see Figure 3 , Figure 4 and Figure 5 The central control box module 300 includes a fixed cover 1, a control box base plate 2, a control drive plate 3, an air inlet connector 4, a power connection terminal 8, a solenoid valve module 10, a second air passage connection structure 11, and a second electrical connection structure 12. The fixed cover 1 is connected to the control box base plate 2 and encloses a space for installing the control drive plate 3 and the solenoid valve module 10.

[0026] The following describes the various components of the central control box module 300: An air inlet connector 4 is mounted on the control box base plate 2 and is used to connect to an external air source. The air inlet connector 4 is connected to the air inlet end of the solenoid valve module 10, and the air outlet end of the solenoid valve module 10 is connected to the second air path connection structure 11. Thus, when the central control box module 300 is installed in the preset installation position, the second air path connection structure 11 can be plugged into and connected to the first air path connection structure 16, so that the gas output by the solenoid valve module 10 enters the air path regulating valve 19 through the first air path connection structure 16, and is further delivered to the pneumatic actuator to drive the electromagnetic shielding device 100 to open, close, or press.

[0027] The power connection terminal 8 is used to connect to an external power source and supply power to the control drive board 3. The control drive board 3 is electrically connected to the solenoid valve module 10, the power connection terminal, and the second electrical connection structure 12. Thus, when the central control box module 300 is installed in the preset installation position, the second electrical connection structure 12 can be plugged into and electrically connected to the first electrical connection structure 15, so that a transmission path for power signals, control signals, and / or feedback signals is formed between the central control box module 300 and the electromagnetic shielding device 100.

[0028] In one embodiment, the central control box module 300 may further include components such as a power switch 5, a DB9 serial port 6, a folding handle 7, and an air hose tee 9. The power switch 5 is used to control the power supply to and from the central control box module 300; the DB9 serial port 6 is used to realize program transmission or remote control connection; the air hose tee 9 is used to distribute the air source connected to the air inlet connector 4 to the solenoid valve module 10; and the folding handle 7 is used to facilitate the operator to pull out or remove the central control box module 300 from the central control box 200.

[0029] Please continue reading. Figure 6 and Figure 7 The second air passage connection structure 11 includes a first sealing plate 24, a first connector mounting plate 26, a sealing ring 29, and at least one first quick-connect air connector 25. The components are described below: The first sealing plate 24 is connected and fixed to the first connector mounting plate 26. The first quick-connect air connector 25 is installed on the first connector mounting plate 26 and is connected to the air outlet of the solenoid valve module 10 in the central control box module 300.

[0030] The sealing ring 29 is disposed on the mating end of the first quick-connect gas connector 30, or on the mating side of the first connector mounting plate 28. When the central control box module 300 is installed in the preset installation position, the first quick-connect gas connector 25 is mated and connected with the second quick-connect gas connector in the first gas connection structure 16. The sealing ring 29 is used to seal the gas connection between the second gas connection structure 11 and the first gas connection structure 16 to prevent gas leakage.

[0031] Therefore, when the central control box module 300 is pushed into the central control box 200, the air circuit connection can be quickly completed; when it is pulled out of the central control box 200, the air circuit connection can be quickly disconnected, which facilitates the disassembly, replacement and maintenance of the central control box module 300.

[0032] Please see Figure 8 and Figure 9 The second electrical connection structure 12 includes a first adjustment plate 34, a first PCB board 35, hexagonal copper pillars 32, and a plurality of first circuit plug-in terminals 37. The first PCB board 35 is fixedly mounted on the first adjustment plate 34 by the hexagonal copper pillars 32, and the plurality of first circuit plug-in terminals 37 are mounted on the first PCB board 35 and electrically connected to the control drive board 3 in the central control box module 300.

[0033] When the central control box module 300 is installed in the preset installation position, multiple first circuit plug-in terminals 37 are plugged into and electrically connected to the corresponding circuit plug-in terminals in the first electrical connection structure 15 to form a transmission path for power signals, control signals and / or feedback signals between the central control box module 300 and the electromagnetic shielding device 100.

[0034] Please return and continue to refer to 3. The central control box 200 includes a shielded chassis 18, a module mounting block 14, a positioning fastener 17, an air circuit regulating valve 19, and a control button 21.

[0035] The module mounting block 14 is mounted on the shielded box chassis 18, and the first electrical connection structure 15 and the first air connection structure 16 are respectively fixed on the module mounting block 14. A positioning fixing member 17 is mounted on the shielded box chassis 18 and / or the module mounting block 14, used to guide and limit the installation direction of the central control box module 300. Specifically, during installation, the central control box module 300 can be pushed into the central control box 200 along the direction defined by the positioning fixing member 17, so that the second electrical connection structure 12 and the first electrical connection structure 15 are accurately connected, and the second air connection structure 11 and the first air connection structure 16 are accurately connected for air passage connection.

[0036] Control button 21 is electrically connected to the first electrical connection structure 15 and is used to send a control signal to the central control box module 300 to control the electromagnetic shielding device 100 to open or close. After receiving the control signal, the central control box module 300 controls the solenoid valve module 10 to operate through the control drive board 3, thereby controlling the pneumatic actuator to drive the electromagnetic shielding device 100 to open or close.

[0037] The pneumatic regulating valve 19 is connected to the first pneumatic connection structure 16 and further connected to the pneumatic actuator. The pneumatic regulating valve 19 is used to regulate the gas flow rate entering the pneumatic actuator, thereby regulating the opening or closing speed of the electromagnetic shielding device 100.

[0038] Thus, the central control box module 300 can be quickly and accurately installed into the preset installation position through the positioning fastener 17, and at the same time complete the electrical and pneumatic connections, which facilitates subsequent quick disassembly, replacement and maintenance.

[0039] Please see Figure 8 and Figure 9 The first electrical connection structure 15 includes a second adjustment plate 31, a second PCB board 33, a hexagonal copper pillar 32, and a plurality of second circuit plug-in terminals 36.

[0040] The second PCB board 33 is fixedly mounted on the second adjustment plate 31 by hexagonal copper pillars 32. Multiple second circuit plug-in terminals 36 are disposed on the second PCB board 33 and electrically connected to the control components on the electromagnetic shielding device 100. The control components may include control buttons 21, detection elements, limit switches and / or other electrical components.

[0041] When the central control box module 300 is installed in the preset installation position, the second circuit plug-in terminal 36 in the first electrical connection structure 15 and the first circuit plug-in terminal 37 in the second electrical connection structure 12 are connected to each other, thereby realizing the transmission of power signals, control signals and / or feedback signals between the central control box module 300 and the electromagnetic shielding device 100.

[0042] Therefore, when the central control box module 300 is pushed into the central control box 200, the first electrical connection structure 15 and the second electrical connection structure 12 can quickly complete the electrical connection; when the central control box module 300 is pulled out, the two can quickly disconnect the electrical connection, thereby avoiding disconnecting and reconnecting wires one by one during maintenance, improving maintenance efficiency and reducing the risk of wiring errors.

[0043] Please return and refer to Figure 6 and Figure 7 The first air passage connection structure 16 includes a second sealing plate 27, a second air connector mounting plate 28, and a second quick-connect air connector 30.

[0044] Specifically, the second sealing plate 27 is connected and fixed to the second air connector mounting plate 28, and the second quick-connect air connector 30 is installed on the second air connector mounting plate 28 and connected to the air circuit regulating valve. The second quick-connect air connector 30 is used to connect with the first quick-connect air connector 25 in the second air circuit connection structure 11 when the central control box module 300 is installed in the preset installation position, so that the solenoid valve module in the central control box module can form an air circuit connection with the pneumatic actuator of the electromagnetic shielding device through the first air circuit connection structure.

[0045] This application also provides an electromagnetic shielding device 100, which includes a device body, a pneumatic actuator 22, and a central control device as described in any of the above embodiments.

[0046] The equipment body has an electromagnetic shielding space, which is used to accommodate the product to be tested and isolate external electromagnetic interference. The equipment body includes a housing door 23, and a pneumatic actuator 22 is disposed on the equipment body and is used to drive the housing door 23 to open, close and / or press.

[0047] The central control device is installed on the equipment body. The first air passage connection structure 16 in the central control device is connected to the pneumatic actuator 22 to provide a gas transmission path to the pneumatic actuator 22. The first electrical connection structure 15 in the central control device is electrically connected to the control components on the equipment body to realize the transmission of control signals, power signals and / or feedback signals.

[0048] When the central control box module 300 is installed in the preset installation position of the central control box 200, the central control box module 300 can control the pneumatic actuator 22 to operate through the first air connection structure 16 and the second air connection structure 11, and is electrically connected to the control components on the equipment body through the first electrical connection structure 15 and the second electrical connection structure 12, thereby realizing the control of the opening, closing and / or pressing action of the cabinet door 23.

[0049] The present invention relates to a central control device and equipment for electromagnetic shielding equipment. By incorporating a first electrical connection structure and a first pneumatic connection structure within a central control box, and correspondingly incorporating a second electrical connection structure and a second pneumatic connection structure on a detachable central control box module, the central control box module can simultaneously achieve rapid plug-and-play connection of the electrical and pneumatic circuits when installed in a preset position, and simultaneously achieve rapid disconnection of the electrical and pneumatic circuits when removed. Therefore, when control components such as the control drive board and solenoid valves of the electromagnetic shielding equipment malfunction, maintenance personnel do not need to disconnect and reconnect wires and pipes individually on-site, nor do they need to spend a long time troubleshooting the wiring and pneumatic circuits. The entire central control box module can be removed and replaced to restore equipment operation, thereby simplifying maintenance operations, reducing the risk of wiring errors and pneumatic leaks, shortening equipment downtime, reducing maintenance costs, and improving production efficiency without affecting the normal control and shielding function of the electromagnetic shielding equipment.

[0050] The specific embodiments of the invention have been described in detail above, but these are merely examples, and the invention is not limited to the specific embodiments described above. For those skilled in the art, any equivalent modifications or substitutions to the invention are also within the scope of this invention. Therefore, all equivalent transformations, modifications, and improvements made without departing from the spirit and principles of this invention should be covered within the scope of this invention.
