Description

Technical Field

[0001] The invention relates to the technical field of metering connection devices, and in particular to a metering connection device for an overhead main line and an electric meter household line. Background Art

[0002] The metering access device is a device used to connect and measure electric energy in the power system. It is usually installed inside the meter box and connected to the meter to ensure accurate measurement and transmission of electricity data. The working principle of the metering access device usually involves the current passing through the contact points of the device, which are connected to the meter so that the meter can measure the electric energy passing through. The design of the device usually takes into account good electrical contact and sufficient mechanical strength to withstand long-term current loads and physical stress. When the meter is connected to the household, the role of the metering access device is particularly important because it ensures that the electricity consumption of each user can be measured individually. This is crucial for the fairness and transparency of billing, especially when one meter box serves multiple users.

[0003] When installing the metering connection device, strip the insulation layer of the cable to be connected by an appropriate length to expose the metal wire core, and then connect the connecting line to the electric meter with the conductor through the metering connection device. The existing metering connection device fixes the conductor and electrically connects the conductor and the cable through the aluminum fixings in the metering connection device. Due to the size of the conductor or cable, the contact area between the aluminum connector and the cable may change, resulting in changes in the conductivity of the current. In order to ensure that the connection between the cable and the conductor will not be affected by the size of the cable and the conductivity of the aluminum connector, we propose a metering connection device for the overhead main line and the meter entrance line.
