Description

Technical Field

[0002] In the power system, the meter box is a key device for electric energy metering. It is a current metering device. The difference between it and the electric energy meter is that the electric energy meter mainly measures the power integral of the circuit per unit time. It is usually used for household meters and industrial electricity metering equipment. The connection stability and safety of the cables inside the meter box are directly related to the reliability and safety of the power supply.

[0003] For example, the patent number disclosed in the China Patent Network is: CN111900666B, and the patent name is: An auxiliary installation device for the incoming cable of an electric power meter box; it includes an upper hoop ring and a lower hoop ring, the upper hoop ring includes a first half ring and a second half ring, the lower hoop ring includes a third half ring and a fourth half ring, the upper hoop ring and the lower hoop ring are connected by a plurality of hoop ring connectors, the right end of the first half ring is rotatably connected to the right end of the second half ring by a rotating connection part, the right end of the third half ring is also rotatably connected to the right end of the fourth half ring by a rotating connection part, a hoop ring tightening part is connected between the left end of the first half ring and the left end of the second half ring, a hoop ring tightening part is also connected between the left end of the third half ring and the left end of the fourth half ring, and a plurality of auxiliary guide parts are connected to the upper hoop ring and the lower hoop ring; the invention has a reasonable overall structure and is easy to use, can fix and guide the incoming cable of the electric power meter box, improves work efficiency and construction quality, and reduces labor intensity and production costs.

[0004] In actual use, a traditional meter box incoming cable auxiliary installation device like this may have some problems when connecting cables. Specifically, there are the following deficiencies: Poor connection stability: Traditional cable connections often rely on simple plugging or screw fixing, which makes it difficult to ensure stable connection of cables during long-term operation. Especially when the cables are subjected to external forces for a long time, they are prone to loosening or falling off, affecting the continuity and stability of power transmission.

[0005] Low safety: The cables inside the existing meter box are sealed by passing through a rubber ring that is clamped inside the meter box when passing through the meter box. If the rubber ring fits tightly with the cable, it will cause the operator to have complicated operations when passing the cable, affecting the installation efficiency. If the rubber ring is large and difficult to fit tightly with the cable, the cable connection will not be effectively sealed and will be easily affected by external environmental factors, such as the intrusion of moisture and dust, resulting in a decrease in the insulation performance of the cable and even causing safety accidents such as short circuits. In response to the above problems, the present invention document proposes an auxiliary connection device for cables inside the meter box. Summary of the invention
