Abstract

The invention provides a live plugging socket connector of a low-voltage metering box. The socket connector is fixed in the low-voltage metering box and is used for installation of an electric energy meter. The socket connector comprises a socket connector base with socket connector columns fixed to one side. The socket connector also comprises an insulating protection member installed on the socket connector base. The insulating protection member includes a body and an insulating protection plate connected to the body. The insulating protection plate can be ejected out of the body or retracted into the body. When ejected out of the body, the insulating protection plate covers the socket connector columns. The socket connector of the low-voltage metering box allows live plugging, facilitates maintenance and meter change by an operator without disconnecting the power, can reduce inconvenience to a user caused by power disconnection for maintenance, effectively avoids human body safety accidents induced by contact with live parts due to misoperation, and can add an antitheft barrier to the metering box.

Description

technical field [0001] The invention relates to a connector, in particular to a live plug connector for a low-voltage metering box for live installation of an electric energy meter. Background technique [0002] With the rapid improvement of the State Grid Corporation's "big marketing" system, the importance of user electricity safety is increasing day by day. In the process of continuous development of smart grid technology, a new type of interference fit connector has emerged. Since the connector adopts the integrated plug-in technology, the traditional screw tightening method is no longer used, which simplifies the work procedures of new installation, replacement and maintenance of electric energy meters on site to a certain extent, but because there is no live plug-in structure and related protection measures, As a result, it is still necessary to operate after power failure during on-site work, which brings great inconvenience to customers who use electricity; if force...
