Abstract

The invention provides an electric energy meter, which includes a casing, a relay and a terminal button assembly. The relay is arranged in the casing, and the conductive sheet of the relay is inserted into the terminal button assembly. Fixed connection, the terminal button base includes a side wall, a bottom wall connected to the side wall, and a limiting plate parallel to the side wall. The side wall, the bottom wall and the limiting plate form a receiving groove for the insertion of the conductive piece. A U-shaped groove is provided to form the main body of the bottom wall and the cantilever beam. The cantilever beam is provided with a first positioning part, and the conductive sheet is provided with a second positioning part matched with the first positioning part. In the electric energy meter provided by the present invention, the side wall, the bottom wall and the limit plate form a receiving groove for inserting the conductive sheet of the relay, and the receiving groove has a certain positioning effect on the conductive sheet, the first positioning part and the second positioning part Cooperate with each other, so that the conductive sheet is completely fixed in the terminal button assembly, without using screws to fix.

Description

technical field [0001] The invention belongs to the technical field of electrical accessories, and more specifically relates to an electric energy meter. Background technique [0002] Energy meters are widely used in large-scale circuit systems. The core device inside the energy meter is a relay. The relay and the terminal button are usually fixed to each other by fasteners such as screws. Specifically: the copper sheet of the screw and the relay and the terminal button The shell is tightly fitted, so that the copper sheet is fixedly connected with the end button. However, when the copper sheet is fixed with screws, the man-hours required to assemble the screws are longer, and the screws increase the contact resistance, causing heat at the connection. Contents of the invention [0003] The object of the present invention is to provide an electric energy meter to solve the technical problems existing in the prior art that the relay and the terminal button are fixed by scre...
