Description

Technical Field

[0001] The utility model relates to the technical field of electric meter boxes, in particular to an electric meter box used for electric power metering. Background Art

[0002] With the development of society, electric power resources have become an indispensable part of people's lives. As an important device for electricity metering, the usage of electric meter boxes is also increasing. Electric meters are usually installed inside the electric meter boxes. The electric meters can be used to perform electricity metering operations and record the amount of electricity used by users. There are many types of electric meter boxes on the market. Most of them are equipped with inspection doors, which are convenient for opening the inspection doors for inspection and other operations.

[0003] Since the meter box needs to be wired when in use, in order to achieve the effect of convenient wiring, the meter box is usually provided with a corresponding through hole, which can be used for the wire to pass through for wiring operation, but only the two ends of this type of through hole are connected to the outside world, and the cable can only be inserted from one side of the through hole and passed out from the other side, and it is not possible to directly insert the cable from the side of the through hole into the through hole. In the specific wiring process, the meter is first installed in the meter box and then the cable is passed through the through hole to the meter for wiring. This type of operation needs to be completed in the meter box. Since the space in the meter box is relatively small and there are many internal electronic devices, it will bring inconvenience to the wiring operation. However, if the cable is directly connected to the meter outside the meter box and then the meter is installed, although the portable wiring operation can be completed, due to the large size of the meter, the meter cannot pass through the cable through hole, which further causes the cable to be unable to be placed in the cable through hole, affecting the normal wiring operation and bringing inconvenience to the user. In view of this, we propose an electric meter box for power metering. Utility Model Content
