Description

Technical Field

[0001] This utility model relates to the field of controllers, and in particular to a modular plastic shell controller. Background Technology

[0002] Conventional intelligent controllers are designed with a CPU as the core, supplemented by multiple functional circuits such as signal input circuits, power input circuits, user settings, indicator lights, tripping execution, and data storage, which together form an inseparable controller unit.

[0003] Based on the needs of switchgear manufacturers during the early development phase, user-defined components are implemented in two forms: encoding and LCD. The common practice is to differentiate between these two modes at the hardware level, and once the switchgear manufacturer selects and installs the device, this mode cannot be changed. However, this unchangeable mode presents many inconveniences in practical applications. For example, when user needs change, or different forms of user-defined components are required in different application scenarios, conventional intelligent controllers cannot adapt flexibly and must be replaced with the entire controller unit to meet the requirements. This not only increases costs but also wastes resources. Utility Model Content

[0004] The technical problem solved by this utility model is to provide a modular plastic shell controller that allows for easy modification of user-defined components.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a modular plastic shell controller, including a main PCB board, on which a control circuit module is fixedly connected, and a first plug-in structure is provided, which is signal-connected to the control circuit module. It also includes a first sub-PCB board and a second sub-PCB board, on which a first functional module is provided, and on which a second functional module is provided. Both the first and second sub-PCB boards are provided with a second plug-in structure for interlocking with the first plug-in structure. When the first and second plug-in structures are interlocked, the control circuit module and the first or second functional module are signal-connected.

[0006] Furthermore, the first functional module is an encoding switch setting circuit module.

[0007] Furthermore, the second functional module is a liquid crystal control circuit module.

[0008] Furthermore, the control circuit module includes a current transformer coil module for connecting to an external power source, a signal input module, a power input module, a CPU processor module, a tripping circuit module, a storage module, and a display circuit module; The current transformer coil module is connected to the signal input module and the power input module respectively; The signal input module, power input module, trip circuit module, storage module, and display circuit module are respectively connected to the CPU processor module.

[0009] Furthermore, the display circuit module is an indicator light.

[0010] Furthermore, the first plug-in structure is a socket, and the second plug-in structure is a pin.

[0011] Furthermore, the first plug-in structure is a pin, and the second plug-in structure is a socket.

[0012] The beneficial effects of this utility model are as follows: By setting the first and second plug-in structures, the first and second PCB boards can be easily plugged into and disassembled with the main PCB board, thereby facilitating changes to the form of user-defined components. When user needs change or different forms of user-defined components are required in different application scenarios, only the corresponding first or second PCB board needs to be replaced, without replacing the entire controller unit, thus reducing costs and avoiding waste of resources. Furthermore, this modular plastic-cased controller also has the advantages of simple structure and ease of implementation. Attached Figure Description

[0013] Figure 1 This is a schematic diagram of the frame structure of the modular plastic shell controller according to an embodiment of this application. Detailed Implementation

[0014] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0015] like Figure 1 As shown in the figure, an embodiment of this application discloses a modular plastic shell controller, including a main PCB board, on which a control circuit module is fixedly connected. The main PCB board is provided with a first plug-in structure, which is signal-connected to the control circuit module. It also includes a first sub-PCB board and a second sub-PCB board. The first sub-PCB board is provided with a first functional module, and the second sub-PCB board is provided with a second functional module. Both the first and second sub-PCB boards are provided with a second plug-in structure for interlocking with the first plug-in structure. When the first plug-in structure and the second plug-in structure are interlocked, the control circuit module and the first functional module or the second functional module are signal-connected.

[0016] Specifically, the first functional module is the encoding switch setting circuit module.

[0017] Specifically, the second functional module is the LCD control circuit module.

[0018] It should be noted that the first and second functional modules mentioned above can also be replaced with other control modules as needed.

[0019] Specifically, this modular molded case controller can be used for circuit breaker control. In practical applications, it is connected to the circuit breaker, and the control circuit module on the main PCB board provides precise control. When user settings are required in coded form, the first PCB board, which contains the coded switch setting circuit module, is plugged into the first plug-in structure on the main PCB board via its second plug-in structure. At this time, the control circuit module and the coded switch setting circuit module are signal-connected, enabling the coded setting function. When the application scenario or user requirements change, and user settings are required via an LCD, simply remove the first PCB board and plug the second PCB board, which contains the LCD control circuit module, into the first plug-in structure on the main PCB board via its second plug-in structure. This allows the control circuit module and the LCD control circuit module to signal-connect, completing the LCD setting operation. This flexible replacement method greatly improves the controller's applicability in different scenarios and effectively reduces costs and resource waste caused by changing requirements.

[0020] In this embodiment, the control circuit module includes a current transformer coil module for connection to an external power source, a signal input module, a power input module, a CPU processor module, a tripping circuit module, a storage module, and a display circuit module; the current transformer coil module is connected to the signal input module and the power input module respectively; the signal input module, the power input module, the tripping circuit module, the storage module, and the display circuit module are connected to the CPU processor module respectively.

[0021] Specifically, the display circuit module displays the current status, the current transformer coil module connects to the external power supply, the signal input module receives external signals and converts them into digital signals that the controller can recognize, and the power input module provides a stable power supply to the entire controller. It employs efficient power conversion technology to convert external power into the stable voltage and current required by the controller, ensuring that the controller will not experience power fluctuations or power outages during long-term operation. The CPU processor module processes various input signals and performs logical operations and control outputs according to preset programs. The trip circuit module quickly cuts off the power supply when the controller detects an abnormal situation to protect the equipment and personnel. The storage module stores various parameters and settings of the controller.

[0022] It should be explained that the circuit structures of the above modules are all existing circuit structures, and no improvements have been made to the circuit structure itself.

[0023] In this embodiment, the display circuit module is an indicator light.

[0024] Specifically, the indicator lights are configured to display the controller's operating status under different conditions. For example, when the controller is operating normally, the indicator light is green; when a fault or abnormal situation occurs, the indicator light turns red, reminding the operator to check and handle the situation promptly. This intuitive display method allows operators to quickly understand the controller's operating status, improving work efficiency and safety.

[0025] In this embodiment, the first plug-in structure is a socket, and the second plug-in structure is a pin, or the first plug-in structure is a pin and the second plug-in structure is a socket.

[0026] Specifically, when the first connector structure is designed as a socket, the corresponding second connector structure uses a pin. This design provides clear guidance during the connection process, allowing operators to quickly and accurately connect the first or second PCB board to the main PCB board. During connection, the pins can smoothly insert into the socket, ensuring stable signal transmission. Moreover, this connection method maintains good contact performance even after multiple insertions and removals, reducing the likelihood of loosening or poor contact.

[0027] Conversely, if the first connector structure is designed as a pin and the second connector structure as a socket, a convenient and quick connection can still be achieved. The rigid structure of the pin ensures sufficient force when inserted into the socket, making the connection more secure. At the same time, the internal structure of the socket provides precise positioning for the pin, preventing it from shifting during insertion, thus ensuring the accuracy of the signal connection between the control circuit module and the first or second functional module.

[0028] In practical applications, operators can flexibly choose the specific form of the first and second plug-in structures according to their specific usage needs and operating habits. Regardless of the combination method, it can meet the requirement of easy replacement of user-defined components in the modular plastic housing controller, further demonstrating the flexibility and practicality of the controller design.

[0029] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
