Abstract

The invention discloses an integrated combined terminal row. The combined terminal row comprises terminals of a strong current terminal row and a weak current terminal row and is characterized in that the combined terminal row also comprises a mounting box body, a mutual inductor, coils and movable and static contact pieces of a relay, wherein the mounting box body is provided with installation positions of the terminals of the strong current terminal row, the mutual inductor and the coils and movable and static contact pieces of the relay, the output end of the fixed contact pieces of the relay is used to connect with the mutual inductor in series and then extend to the terminals of the strong current terminal row to connect with an external power supply, and the terminal of the movable terminal extends to the back of the terminals of the strong current terminal row to be introduced. The integrated combined terminal row of the invention can reduce the contact resistance and the total calorific power of an electric energy meter so that the installation efficiency of the electric energy meter is significantly improved, the operation is reliable, the structure is compact, the service life is increased and the cost is reduced.

Description

technical field [0001] The invention relates to a terminal block for an electric energy meter. Background technique [0002] Existing watt-hour meters generally have terminal blocks, transformers, and relays, which are independent of each other in structure. When installing watt-hour meters, they need to be fastened and installed in the meter box with fasteners and connectors, and then Connect each electrical connection point with a cable (e.g. Figure 6 shown). The installation of the electric energy meter with this structure is very time-consuming, and the installation quality cannot be guaranteed. Moreover, due to the large number of electrical connection points and the large heat generation, it is very unfavorable to the service life and reliability of the electric energy meter, resulting in an increase in the overall cost. Contents of the invention [0003] The purpose of the present invention is to provide an integrated combined terminal block integrating the functi...
