Description

Electric energy meter connector connected by transformer

technical field

The present invention relates to a connector for an electric energy meter connected through a transformer, which belongs to the field of electric power meter installation.

Background technique

With the transformation of the national grid and the popularization of smart grids, the installation workload of electric energy meters has greatly increased, and the requirements for electrical safety and reliability of the installed meters have also increased. The "convenient, fast and safe" installation requirements for electrical meters have been put forward.

At present, the installation and electrical connection of the transformer-connected electric energy meter in the meter box is connected to the joint test junction box by means of wires. However, the reliability of the wire connection method is poor, the wiring of the test box is complicated, and it is easy to connect wrongly. .

Aiming at the deficiencies in the prior art, the present invention provides a transformer-connected electric energy meter connector.

The present invention is realized by following technical scheme:

A connector for an electric energy meter connected through a transformer, including a plug-in base (1), a plug-in cover (2), a plug-in electrical connector (4), a buckle (5), and a joint test junction box (13); The plug-in electrical connector (4) and the joint test junction box (13) are installed on the plug-in base (1); the plug-in cover (2) is fixed on the plug-in base (1) through screw connection; the joint There is an electrical test connection piece (14) inside the test junction box (13), and the lower end of the joint test junction box (13) is connected with a connection hole (10) connected with a wire; the electric energy meter is fixed on the on the plug-in base (1).

The joint test junction box (13), the plug-in electrical connector (4), and the plug-in base (1) are of an integrated structure.

Electrical test equipment wiring jacks (15) are arranged in the joint test junction box (13) and are on the same horizontal line.

A group of electrical plugs (11) corresponding to the holes of the electric energy meter and RS485 communication connection plugs (16) are installed on the above-mentioned plug-in electrical connector (4). 16) Realize plug-in connection.

The upper end of the electrical plug (11) is a cross-slit elastic cylinder (21), and the lower end is a connection terminal or a wire crimping hole.

In the present invention, through the integrated design of the electrical plug-in and the joint junction box, the installation of the transformer-connected electric energy meter, the electrical connection and the RS485 communication connection do not require on-site wiring, and the on-site installation of the electric energy meter is realized through simple plugging and unplugging actions.
