In other words, micro-metering devices face difficulties in hardware board layout in order to realize the functions of ordinary energy meters.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

Another core aspect of this invention is to provide a circuit breaker including the above-mentioned micro-integrated metering switch measurement module layout structure.

[0040] This specific embodiment provides a micro-integrated metering switch measurement module layout structure, including:
[0041] LCD PCB board 1;
[0042] The power supply PCB board 2 is vertically disposed on one side of the LCD PCB board 1;
[0043] Communication PCB board 3 is vertically disposed on the other side of LCD PCB board 1;
[0044] Connector 4 is vertically positioned between the power PCB board 2 and the communication PCB board 3;
[0045] The housing 5 is used to enclose the LCD PCB board 1, the power PCB board 2 and the communication PCB board 3, and to close the notch end opposite to the LCD PCB board 1. The side of the housing 5 that is used to fit with the LCD PCB board 1 is provided with a window 51, and the window 51 is correspondingly set with the LCD screen 11 of the LCD PCB board 1.
[0046] It should be noted that, please refer to Figures 4 to 7 The housing 5 is typically made of insulating material. Its function is to isolate the internal gas from the external environment, while also providing structural strength and resistance to shock and pressure. Furthermore, the housing 5 can be a modular structure to facilitate the installation of various components within it, and it must be compatible with each PCB board.
[0047] In addition, it should be noted that the LCD PCB board 1 is mainly responsible for connecting and controlling the various components of the LCD screen 11, such as the driver IC and the character IC, to ensure the normal operation of the LCD screen 11. The power PCB board 2 is equipped with a power supply, which is used to connect the various parts of the circuit to form a complete circuit system. The communication PCB board 3 is equipped with a Bluetooth communication device, which is used to realize the connection and signal transmission between the various components in the electronic device, facilitating remote Bluetooth control. Moreover, in addition to the LCD screen 11 communicating with the outside world through the housing 5, the buttons on the LCD PCB board 1 can also communicate with the outside world through the housing 5, so that the operator can control the LCD screen 11 to switch operations.
[0048] In practical applications, the shape, structure, size, and type of the LCD PCB board 1, power PCB board 2, communication PCB board 3, connector 4, and housing 5 can be determined according to the actual situation and needs.
[0049] When using the micro-integrated metering switch measurement module layout structure provided by this utility model, firstly, the LCD PCB board 1 and the power PCB board 2 can be vertically connected. Then, the connected LCD PCB board 1 and power PCB board 2 are placed and fixed in the housing 5. Next, the communication PCB board 3 is inserted into the housing 5, and the communication PCB board 3 and the LCD PCB board 1 are vertically connected, as shown in the diagram. Figure 1As shown. Finally, the notch opposite to the LCD PCB1 is closed by the housing 5, and the LCD screen 11 is connected to the outside world through the window 51 to display the interface and data, etc.
[0050] This device divides the metering side circuit of the electricity meter into three parts: an LCD PCB board 1, a power supply PCB board 2, and a communication PCB board 3. This effectively modularizes the overall functions of the electricity meter, reducing the design cycle and facilitating later maintenance and debugging. In other words, this device can implement the functions of a standard electricity meter within a limited space while ensuring good electrical isolation and reliable connection. Furthermore, the modular division of each functional area facilitates later maintenance and debugging.
[0051] In summary, the micro-integrated metering switch measurement module layout structure provided by this utility model can realize the function of an electricity meter and complete the hardware layout operation within a limited space.
[0052] In one embodiment, both the communication PCB board 3 and the power PCB board 2 are provided with tenon and mortise protrusions 6, and the corresponding positions of the liquid crystal PCB board 1 are provided with tenon and mortise slots 7. The tenon and mortise protrusions 6 and the tenon and mortise slots 7 are engaged and fixed. That is, by engaging and fixing the tenon and mortise protrusions 6 and the tenon and mortise slots 7, the power PCB board 2 and the liquid crystal PCB board 1, and the communication PCB board 3 and the liquid crystal PCB board 1 can be initially fixed.
[0053] In one embodiment, the communication PCB board 3 and the liquid crystal PCB board 1 are respectively provided with through holes for passing through the right-angle bent pin 8. The right-angle bent pin 8 and the through holes are welded and fixed, that is, the communication PCB board 3 and the liquid crystal PCB board 1 can be reinforced by welding the right-angle bent pin 8.
[0054] The power PCB board 2 and the LCD PCB board 1 are respectively provided with through holes for passing through the right-angle bent pin 8. The right-angle bent pin 8 is welded and fixed to the through hole, that is, the power PCB board 2 and the LCD PCB board 1 can be reinforced by welding the right-angle bent pin 8.
[0055] It should be noted that this device employs a mortise and tenon structure design and a reinforcement design using right-angle bent pins 8. Utilizing the already fixed power PCB board 2 and communication PCB board 3, the LCD PCB board 1 is secured, ensuring reliable and secure connection throughout the entire button press stroke on the LCD PCB board 1. This also eliminates other structures inside the housing 5 used to limit the movement of the LCD PCB board 1, further increasing the internal space utilization of the device. Furthermore, in addition to using the right-angle bent pins 8 to reinforce the PCB boards, solder pads can also be used to reinforce two vertically connected PCB boards.
[0056] In one embodiment, the housing 5 is provided with at least one rivet hole 9 for installing rivets. The rivets are used to connect the communication PCB board 3 and the power PCB board 2, so as to further strengthen the structural stability of the communication PCB board 3 and the power PCB board 2 through the rivets.
[0057] In one embodiment, the outer wall of the rivet hole 9 is provided with a reinforcing rib, and the power PCB board 2 is provided with a rib groove 21, which is used to restrict the rotation of the reinforcing rib.
[0058] It should be noted that rivet holes 9 can be provided inside the housing 5, and reinforcing ribs can be provided on the outer wall of the rivet holes 9. Correspondingly, rivet holes 9 for rivets to pass through can be provided on the power PCB board 2, and rib grooves 21 for engaging and fixing with the reinforcing ribs can be provided around the rivet holes 9. The communication PCB board 3 and the power PCB board 2 can be fixedly connected by rivets. Due to the engagement and fixing of the reinforcing ribs and rib grooves 21, the torsional rigidity of the housing 5 can be improved, and the power PCB board 2 and other components in the relay component can be prevented from rotating easily when the motor rotates.
[0059] In one embodiment, the outer diameter of the reinforcing rib gradually decreases from the end near the power PCB board 2 to the end near the communication PCB board 3, and the end of the reinforcing rib abuts against the communication PCB board 3.
[0060] It should be noted that when assembling the micro-integrated metering switch measurement module board structure, firstly, the LCD PCB board 1 and the power PCB board 2 can be fastened together using the tenon protrusion 6 and tenon groove 7. Then, through the through holes on the LCD PCB board 1 and the power PCB board 2, right-angled pins 8 are used to weld and fix the LCD PCB board 1 and the power PCB board 2 in place. Next, the LCD PCB board 1 and the power PCB board 2 are placed in the housing 5, and their positions are limited by the rivet holes 9 and reinforcing ribs of the housing 5 to prevent rotation. Subsequently, the communication PCB board 3 is fastened to the tenon groove 7 of the LCD PCB board 1 through the tenon protrusion 6, and fixed by welding through the through holes on the communication PCB board 3 and the LCD PCB board 1 using right-angled pins 8, thus completing the connection and installation of the three PCB boards.
[0061] It should also be noted that rivet holes 9 are provided inside the housing 5, and reinforcing ribs are added to the outer wall of the rivet holes 9. This serves two purposes: firstly, it supports the power PCB board 2, and secondly, it increases the torsional rigidity of the housing 5 to prevent the lateral torque generated by the motor from opening the housing 5. Furthermore, the outer diameter of the reinforcing ribs gradually decreases from the end closer to the power PCB board 2 towards the end closer to the communication PCB board 3, to facilitate the installation of the LCD PCB board 1, power PCB board 2, and communication PCB board 3. This device effectively improves the reliability of the overall PCB layout, the torsional strength of the housing 5, and the utilization rate of the internal space of the device.
[0062] In one embodiment, the connector 4 includes three double-molded pins disposed between the communication PCB board 3 and the power PCB board 2. The three double-molded pins are arranged in a triangular pattern, and each double-molded pin is positioned to avoid circuit breaker components. That is, the double-molded pins can be placed at appropriate locations on the communication PCB board 3 and the power PCB board 2 (i.e., avoiding circuit breaker components and following the principle of electrical isolation), and multiple double-molded pins can form a stable triangular structure to improve the torsional stiffness of the communication PCB board 3 and the power PCB board 2.
[0063] It should be noted that the dual-molded pin is a connector assembly widely used in the electronics field, primarily for connecting circuits. A dual-molded pin is a pin with two plastic housings, typically used as connector 4 on a PCB board. Its main function is to provide electrical connections between circuits, enabling different electronic components to communicate with each other, i.e., allowing communication PCB board 3 and power PCB board 2 to communicate with each other.
[0064] In addition to the aforementioned micro-integrated metering switch measurement module layout structure, this utility model also provides a circuit breaker including the micro-integrated metering switch measurement module layout structure disclosed in the above embodiments. This circuit breaker includes a switching side and a metering side connected to the switching side to achieve the functions of a conventional circuit breaker. The metering side is any of the micro-integrated metering switch measurement module layout structures described above. The structures of other parts of this circuit breaker are described in the prior art and will not be repeated here.
[0065] In one embodiment, the switch side includes an electric motor as the power source for the circuit breaker, a contactor and a relay for controlling the switching action of the circuit breaker, and an operating device for realizing the automatic control function of the circuit breaker.
[0066] In one embodiment, the switch side further includes a protection device and a fuse. The protection device ensures the safe operation of the circuit when an overload or short circuit occurs in the circuit breaker, and the fuse promptly disconnects the circuit when an overload or short circuit occurs. In practical applications, the switch side, the metering side, and the connection method between the switch side and the metering side can be determined according to actual conditions and needs.
[0067] Furthermore, isolating switches, arc chambers, and arc-extinguishing systems can be selectively installed on the switch side. The isolating switch completely isolates the circuit when it is broken, effectively preventing damage from hazardous factors. When the circuit breaker performs switching operations, an electric arc is generated. The arc chamber absorbs and cools the arc, preventing damage to equipment. Typically, the arc chamber is filled with compressed air, oil, or a mixture of air and oil to provide sufficient cooling and arc-extinguishing capacity. The arc-extinguishing chamber is designed to quickly extinguish the arc and protect equipment. It usually includes the arc-extinguishing chamber itself, an arc-extinguisher, and an arc-extinguishing agent. The arc-extinguishing chamber allows the arc to develop into a sufficiently large space for the arc-extinguisher to work effectively. The arc-extinguisher generates air or liquid flow to cool and separate the arc, while the arc-extinguishing agent consumes the arc's energy and extinguishes it.
[0068] In addition, it should be noted that the orientation or positional relationship indicated by "vertical", "parallel", etc. in this application is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the purpose of simplifying the description and making it easier to understand, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

Similar or identical parts between embodiments can be referred to interchangeably. Any combination of all embodiments provided by this utility model is within the protection scope of this utility model and will not be elaborated upon here.
