Description

Technical Field

[0001] The utility model relates to the technical field of electric energy meters, in particular to an anti-misconnection electric energy meter. Background Technique

[0002] An electric energy meter is an instrument used to measure electric energy, also known as a kilowatt-hour meter, a fire meter, or a kilowatt-hour meter, which refers to an instrument for measuring various electrical quantities. When using an electric energy meter, it should be noted that under low voltage (not exceeding 500 volts) and small current (tens of amperes), the electric energy meter can be directly connected to the circuit for measurement. Under high voltage or large current conditions, the electric energy meter cannot be directly connected to the line and needs to be used in conjunction with a voltage transformer or a current transformer.

[0003] After retrieval, a Chinese patent with the publication number CN215816680U discloses an intelligent electric energy meter with an anti-misconnection wire joint structure, including a main body and a joint assembly. The joint assembly includes a fixed shell and an installation hole opened on the surface of the fixed shell. A limiting groove is opened on the inner wall of the fixed shell. One end of the fixed shell is movably connected through a clamping shell, and insulating rubber rings are arranged at the upper and lower ends of the clamping shell.

[0004] When the device moves by squeezing the inner wall of the fixed shell through the limiting block, the second spring is squeezed at the same time. The connecting rod drives the arc-shaped plate to squeeze the wire until the limiting block enters the limiting groove, and then the wire is connected by screwing a screw in the installation hole. Each plug has a corresponding clamping shell, which achieves the effect of preventing misconnection of the wire and also plays a role in fixing it. The operation is simple and the use is convenient.

[0005] However, the device still has the following problems. A groove is opened on the side surface of the main body of the device, and then three groups of joint assemblies are fixedly connected to the inner wall of the groove. When wiring, the wire is inserted into the insulating rubber ring inside the clamping shell, and then the wire and the clamping shell are installed in the installation hole at the bottom end of the fixed shell. In the actual use process, when wiring, first, the electric energy meter needs to be hung in the meter box. Therefore, the electric energy meter is at a relatively fixed angle during wiring, which is not convenient for the staff to observe the wiring port and it is difficult to improve the wiring efficiency.
