Description

Technical Field

[0001] This utility model relates to the field of measurement switch technology, and in particular to a layout structure of a measurement switch. Background Technology

[0002] Measuring switches are key components in power systems for energy metering, line control, and signal transmission. They are widely used in low-voltage distribution areas, and their layout and structure directly affect the stability of equipment operation, ease of assembly, and reliability. During operation, the switching contact assembly generates a significant amount of heat when switching current. To ensure overall structural stability, current technologies generally use bakelite as the main structural material. Bakery possesses excellent heat resistance and insulation properties, effectively resisting the heat generated by the contact assembly. However, bakelite processing is complex, difficult to mold, and cannot be reprocessed. Given the limited overall size of the measuring switch, the flexibility of structural design is significantly reduced. Measurement switches typically integrate a carrier module and a battery compartment. The carrier module handles signal transmission and interaction, while the battery compartment provides power. According to PCB layout principles, the battery compartment should be placed close to the carrier module to shorten the electrical connection path and reduce interference. However, existing bakelite main structures are limited by processing performance and size, making it impossible to reserve space for the battery compartment at the edge of the carrier module. The battery compartment must be placed at the operating mechanism location. This not only makes the electrical connection between the battery compartment and the carrier board prone to loosening due to vibration of the operating mechanism, but also results in cumbersome wiring due to the large distance between them, increasing assembly costs and signal interference, reducing equipment reliability, and hindering later maintenance. Furthermore, bakelite has high processing costs and is difficult to recycle, which does not align with the industry trend of energy conservation, environmental protection, and low cost. Conventional plastic shell materials, with excellent processing performance and lower cost, have poor heat resistance and cannot withstand the large amount of heat generated by the contact components, making them difficult to replace bakelite as the main material. In summary, the current measurement switch layout, due to contact heat generation, can only use bakelite with poor processing properties, leading to unreasonable battery compartment placement and difficulties in electrical connection, thus affecting the performance of the measurement switch. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a layout structure for a measuring switch. Its structure is simple and its layout is reasonable, making the battery compartment more convenient to use, and the wiring connection is reasonable, resulting in good performance.

[0004] To achieve the above objectives, this utility model provides a layout structure for a measuring switch, including a plastic shell. An operation module, a carrier module, and a measuring module are sequentially arranged on the plastic shell along its length. The operation module includes several disconnecting components. The shell of each disconnecting component is made of bakelite. A disconnecting groove is provided on the plastic shell corresponding to the position of the disconnecting component. The disconnecting component is assembled in the disconnecting groove. A battery slot is provided on the side of the plastic shell next to the carrier module. A battery compartment is assembled in the battery slot.

[0005] The advantages of this design are as follows: Using bakelite to construct the casing of the switching component effectively isolates the large amount of heat generated during current switching, preventing high temperatures from affecting the external structure and internal electronic components, thus ensuring the structural stability and electrical safety of the measuring switch during long-term operation. Independently assembling the switching component in the switching slot of the plastic casing allows for the use of plastic casing materials with superior processing performance, significantly improving the flexibility of the structural layout while meeting overall size limitations. Simultaneously, directly placing the battery slot and battery compartment next to the carrier module allows for close placement of the battery compartment, effectively shortening the electrical connection distance between the battery compartment and the circuit board, simplifying the wiring structure, reducing assembly difficulty, minimizing signal interference and poor contact risks caused by excessively long wires, and improving the overall operational stability and reliability of the measuring switch.

[0006] Furthermore, a carrier circuit board is provided in the plastic shell at the position corresponding to the carrier module, and a main circuit board is provided in the plastic shell at the position corresponding to the measurement module. The carrier circuit board is positioned above the main circuit board. The carrier circuit board and the main circuit board are provided with carrier pins and carrier terminals for connection at the overlapping position. A notch is formed on the carrier circuit board at the position corresponding to the battery compartment to expose the main circuit board. The battery compartment passes through the notch and is electrically connected to the main circuit board.

[0007] The advantages of this design are as follows: The carrier circuit board is stacked on top of the main circuit board, and direct plug-in connection is achieved using carrier pins and connectors, eliminating the need for traditional wire connections. This results in a more compact structure, a more robust and reliable connection, and effectively improves the signal transmission stability between modules. A notch is created on the carrier circuit board corresponding to the battery compartment, allowing the battery compartment to directly connect to the main circuit board through the notch. This further optimizes the power supply path, reduces line loss, minimizes electromagnetic interference, and facilitates assembly and subsequent maintenance, while also improving the integration and operational reliability of the measurement switches.

[0008] Furthermore, a power circuit board is also provided in the plastic shell. The power circuit board is located below the main circuit board, and power supply pins and power supply terminals are provided at the overlapping position of the power circuit board and the main circuit board for connection.

[0009] The advantages of this design are: placing the power supply circuit board below the main circuit board, forming a vertically stacked layout, fully utilizes internal space, reduces the overall size of the measurement switch, and achieves a compact and miniaturized structure. Direct connection between the power supply circuit board and the main circuit board is achieved through power supply pins and terminals, ensuring stable connection and reliable conductivity, avoiding issues such as tangled or loose wires, improving power supply stability, and guaranteeing continuous and stable operation of the measurement switch under complex working conditions. Simultaneously, it simplifies the internal structure and improves production and assembly efficiency.

[0010] Furthermore, the battery compartment is provided with a battery cover, and the battery cover is provided with a cover handle.

[0011] The benefits of this design are as follows: The battery cover effectively protects the battery, preventing dust and moisture from entering the compartment, thus avoiding poor contact or short circuits and improving safety. The handle on the battery cover allows for quick and easy opening and closing, making battery installation and removal more convenient and effortless, enhancing the user experience. Furthermore, the design is simple, has low manufacturing costs, and is highly practical. Attached Figure Description

Along its length, an operation module 2, a carrier module 3, and a measurement module 4 are sequentially arranged on the plastic shell 1. The operation module includes several disconnecting components. The shells of the disconnecting components are made of bakelite. Disconnecting grooves are provided on the plastic shell 1 corresponding to the positions of the disconnecting components. The disconnecting components are assembled in the disconnecting grooves. A battery slot is provided next to the carrier module 3 on the plastic shell 1, and a battery compartment 5 is assembled in the battery slot. The advantages of this design are: by using bakelite to make the shells of the disconnecting components, the large amount of heat generated by the disconnecting components during current switching can be effectively isolated, avoiding the impact of high temperatures on the external structure and internal electronic components, and ensuring the structural stability and electrical safety of the measurement switch during long-term operation. By independently assembling the disconnecting components in the disconnecting grooves of the plastic shell 1, the external body can use the plastic shell 1 material with better processing performance, significantly improving the flexibility of the structural layout while meeting overall size limitations. Meanwhile, by directly setting the battery slot and battery compartment 5 next to the carrier module 3, the battery compartment 5 can be arranged close to the carrier module 3, which effectively shortens the electrical connection distance between the battery compartment 5 and the circuit board, simplifies the wiring structure, reduces the assembly difficulty, reduces the risk of signal interference and poor contact caused by excessively long wires, and improves the overall operational stability and reliability of the measurement switch.

The notch in the carrier circuit board 31 at the position corresponding to the battery compartment 5 allows the battery compartment 5 to pass through the notch and be directly electrically connected to the main circuit board 41, further optimizing the power supply path, reducing line loss, reducing electromagnetic interference, and facilitating assembly and subsequent maintenance, while improving the integration and operational reliability of the measurement switch.

[0015] Furthermore, a power circuit board 6 is also provided in the plastic shell 1. The power circuit board 6 is located below the main circuit board 41, and power supply pins and terminals are provided at the overlapping position of the power circuit board 6 and the main circuit board 41 for connection. The beneficial effects of this arrangement are: placing the power circuit board 6 below the main circuit board 41 forms a vertical stacked layout, which can make full use of the internal space, reduce the overall size of the measuring switch, and achieve a compact and miniaturized structure. The direct connection between the power circuit board 6 and the main circuit board 41 is achieved through the power supply pins and terminals, which ensures stable connection and reliable conductivity, avoids problems such as wire tangling and loosening, improves power supply stability, ensures continuous and stable operation of the measuring switch under complex working conditions, and simplifies the internal structure, thereby improving production and assembly efficiency.

[0016] Furthermore, the battery compartment 5 is provided with a battery cover, and the battery cover is provided with a handle.
