Description
Technical Field
[0001] This utility model relates to the field of power transmission equipment technology, and in particular to the wiring terminal equipment for power metering boxes. Background Technology
[0002] An electricity metering box is a device used in power systems, particularly for electricity metering, monitoring, and management. Its main functions are to install electricity meters, measure and record electrical energy, and also to protect circuits, distribute current, and provide electrical access. It typically plays a crucial role in ensuring normal electricity usage, accurate billing, and system safety in power supply and consumption systems. A terminal block is a device used for electrical connections, connecting wires and transmitting electrical signals and current. It usually consists of a series of metal terminals, with wires secured to the terminals using screws, springs, and other connection methods to achieve circuit continuity.
[0003] In existing technologies, the wiring terminal equipment of some electricity metering boxes mainly consists of terminal blocks, conductive copper strips, and insulating supports. The terminal blocks are used to connect power input, load output, and current transformers, ensuring accurate signal transmission from the electricity meter. The conductive copper strips are used to achieve efficient current conduction, while the insulating supports ensure the safety of the wiring terminals, preventing accidents such as short circuits and leakage. During operation, the electricity box uses these terminals to achieve stable current and voltage transmission between the power supply and the metering equipment, ensuring accurate measurement and recording of electricity consumption data by the electricity meter, while also ensuring the safe operation of the system.
[0004] However, in practical use, some terminal block devices typically require screws to secure cables. This design is time-consuming and requires specialized tools. In emergencies, such as power system failures, this design can lead to excessively long repair times. Furthermore, existing terminal block devices are usually fixed inside the electricity metering box, making maintenance and replacement difficult. This not only increases maintenance time but also raises safety risks for maintenance personnel. To address these issues, a new terminal block device for electricity metering boxes is proposed.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] Reference Figure 1 , Figure 2 and Figure 4 This utility model provides an embodiment of an electrical metering box terminal block device, including a fixed box 1. The fixed box 1 is generally rectangular in shape and made of high-strength cold-rolled steel plate. It undergoes surface anti-rust treatment, exhibiting good pressure resistance, impact resistance, and corrosion resistance, effectively protecting internal electrical components and other structures. The fixed box 1 has elongated grooves 2 at its upper and lower ends, which are rectangular slots used for installing and positioning components of the mounting mechanism. The fixed box 1 has mounting mechanisms rotatably connected to its upper and lower ends. These mounting mechanisms include connecting rotating columns 3, which are cylindrical and made of alloy steel, heat-treated to achieve high strength. It has good strength and wear resistance, and can withstand the torque and friction during rotation. The upper and lower ends of the connecting rotating column 3 are rotatably connected to the upper and lower ends inside the fixed box 1 through the rotating connection structure of shaft and bearing, so that the connecting rotating column 3 can rotate flexibly inside the fixed box 1. The upper and lower ends of the connecting rotating column 3 are rotatably connected to the upper and lower ends inside the fixed box 1. The external of the connecting rotating column 3 is fixedly connected to the rotating connecting plate 4. The rotating connecting plate 4 is rectangular and made of aluminum alloy, which has good strength and lightness. Under the drive of the connecting rotating column 3, the rotating connecting plate 4 can rotate around the axis of the connecting rotating column 3, thereby adjusting the angle of the electrical component assembly, which is convenient for operation and maintenance.
[0034] An electrical component assembly is fixedly connected to the outside of the rotating connecting plate 4. The electrical component assembly includes a first energy meter 5, which is rectangular in shape and made of fire-resistant and insulating engineering plastic. It integrates a high-precision current transformer, voltage transformer, and metering chip, which can accurately measure the energy consumption in the circuit. The first energy meter 5 is fixedly connected to the outside of the rotating connecting plate 4, and the outside of the rotating connecting plate 4 is rotatably connected to the inside of the fixed housing 1.
[0035] The rotating connecting plate 4 is externally fixedly connected to a connecting assembly, which includes multiple fixed transverse plates 6. The fixed transverse plates 6 are rectangular plates made of aluminum alloy, possessing good corrosion resistance and surface hardness. The fixed transverse plates 6 are externally fixedly connected to the rotating connecting plate 4 by welding. Multiple fixed transverse plates 6 are evenly distributed on the rotating connecting plate 4. Multiple limiting grooves 7 are formed on the external surface of the fixed transverse plates 6. These limiting grooves 7 are rectangular grooves used to limit the position and movement trajectory of the first terminal blocks 8. Multiple first terminal blocks 8 are slidably connected to the external surface of the fixed transverse plates 6. The first terminal blocks 8 are cuboid blocks made of copper alloy with good conductivity, and their surfaces are tin-plated to improve their conductivity and oxidation resistance. Externally, a fixed connecting post 9 is fixedly connected by welding. The first terminal 8 is externally fixedly connected to the fixed connecting post 9. The fixed connecting post 9 is cylindrical and made of stainless steel, which has high strength and corrosion resistance. The fixed connecting post 9 is externally slidably connected to the inside of the fixed horizontal plate 6. The inside of the fixed horizontal plate 6 is slidably connected to the outside of the limiting sliding ball 10. The limiting sliding ball 10 is spherical and made of stainless steel, which has high strength and wear resistance. The limiting sliding ball 10 slides in the limiting groove 7 of the fixed horizontal plate 6, thereby driving the first terminal 8 to slide on the fixed horizontal plate 6, realizing the adjustment of the line connection position. When adjusted to the appropriate position, the limiting sliding ball 10 can be locked in a specific position of the limiting groove 7 to fix the position of the first terminal 8.
[0036] Reference Figure 1 , Figure 3The fixed housing 1 has multiple ventilation holes 12 on its exterior. The ventilation holes 12 are circular and their function is to increase air circulation and improve heat dissipation. Multiple heat dissipation mechanisms are rotatably connected inside the fixed housing 1. The heat dissipation mechanism includes a cooling fan 13. The cooling fan 13 is circular and the fan blades are made of aluminum alloy, which has good strength and lightweight characteristics. It generates a strong airflow to expel hot air from the housing and introduce cool air from the outside, thus achieving the heat dissipation function. The cooling fan 13 is rotatably connected to the interior of the fixed housing 1. A fixed heat dissipation plate 14 is fixedly connected inside the fixed housing 1. The fixed heat dissipation plate 14 is rectangular and made of copper plate with good thermal conductivity. The fixed heat dissipation plate 14 can absorb the heat generated by the electrical components and transfer the heat to the air, further improving the heat dissipation efficiency. A dust filter plate 15 is fixedly connected inside the fixed housing 1. The dust filter plate 15 is rectangular and made of metal filter mesh with good air permeability and filtration performance. It can effectively filter dust and impurities entering the housing and protect the electrical components from contamination.
[0037] A cleaning assembly is slidably connected to the outside of the dust filter plate 15. The cleaning assembly includes two cleaning brush plates 16, which are rectangular plates made of plastic with soft nylon bristles that provide good cleaning performance. The sides of the two cleaning brush plates 16 that are close to each other are slidably connected to the outside of the dust filter plate 15. A connecting transfer plate 17, which is rectangular and made of aluminum alloy, is fixedly connected to the outside of the cleaning brush plates 16. The two connecting transfer plates 17 are fixedly connected by welding to each other via a U-shaped connector. Plate 11, two connecting transfer plates 17 are externally fixedly connected to a U-shaped connecting plate 11. The U-shaped connecting plate 11 is in the shape of a U and is made of aluminum alloy. When it is necessary to clean the dust filter plate 15, the connecting transfer plate 17 and the cleaning brush plate 16 can be driven to slide up and down in the fixed box 1 by pushing the U-shaped connecting plate 11. The bristles of the cleaning brush plate 16 contact the surface of the dust filter plate 15 to clean away the dust and ensure the normal operation of the dust filter plate 15. The outer sides of the fixed box 1 have elongated holes for the sliding of the cleaning components. The left and right sides of the inside of the fixed box 1 are slidably connected to the outside of the connecting transfer plate 17.
[0038] Working principle: First, by holding the handle on the side of the rotating connecting plate 4, the rotating connecting plate 4 is rotated and slid along the elongated groove 2 inside the fixed housing 1, so that internal components, such as the first terminal 8, can be easily exposed to the outside, which facilitates the worker to carry out later maintenance and inspection. At the same time, by sliding the limiting sliding ball 10 at the rear of the first terminal 8 against the hole inside the fixed transverse plate 6, and then sliding to other grooves for limiting, it is easy to pick up and disassemble later.
[0039] During equipment operation, in order to maintain internal temperature and cleanliness, the cooling fan 13 is activated, allowing external air to enter the interior of the fixed housing 1 and then be circulated through the fixed heat dissipation plate 14 to achieve internal heat dissipation. The U-shaped connecting plate 11 is held and driven by the connecting transfer plate 17 to move the cleaning brush plate 16 up and down, thereby cleaning the surface of the dust filter plate 15 on both sides and ensuring smooth internal heat dissipation.
[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
