Problems solved by technology
There is still room for improvement in the safety performance of the existing electric energy meter connectors. For example, in the patent CN 105548637 A, the automatic short circuit will only be performed when the electric energy meter is completely pulled out of the connector. In addition, the existing electric energy meter connector is not equipped with a device for automatically detecting the connection status between the electric energy meter and the connector, so during the installation process of the electric energy meter, it is necessary to judge the electric energy meter and the connector by naked eyes and experience. Whether the connectors are plugged in place, the judgment is not accurate, and the operation is inconvenient

The invention discloses an electric energy meter connector with an acousto-optic alarm and automatic shorting function, which comprises a sound device (7) and an indicator light (8) disposed on a base (1) and electrically connected with a circuit board, six current contacts (2) electrically connected to a current fixed contact (11), and four voltage contacts (3) electrically connected to a voltage fixed contact (13). The inner side of the base (1) is provided with a push buckle (4) and a plurality of press buckles (4). The rear ends of the press buckles (4) are fixedly connected with a current moving contact (12) and a voltage moving contact (14) through springs (10), and the current fixed contact (11) is located just below the current moving contact (12). One end of the voltage moving contact (14), the middle of which is fixedly connected to the press buckles (4), is located just below the voltage fixed contact (13). The electric energy meter connector has an acousto-optic alarm function, can automatically disconnect a circuit, is safe and reliable, and convenient to control.
Description
technical field [0001] The invention relates to an electric energy meter connector device in the technical field of electric power, in particular to an electric energy meter connector with sound and light alarm and automatic short circuit function. Background technique [0002] Energy meters are instruments used to measure electric energy, also known as watt-hour meters. According to their working principles, they can be divided into inductive energy meters, static energy meters and electromechanical integrated energy meters. With the transformation and upgrading of the power grid, electric energy meters are widely used in the field of electric power. The State Grid stipulates that the installation of electric energy meters should be realized through special connectors for electric energy meters. The wires must not be directly connected to electric energy meters. , in order to realize the fast, convenient, safe and reliable installation function of the electric energy meter....
