Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary devices for electric energy meter detection, in particular to an auxiliary wiring device for an electric energy meter. Background Art

[0002] Electricity meters need to be tested for various functions before leaving the factory. Some current electricity meters have pins extending from their lower ends for testing wiring, while others have sockets at their lower ends for testing wiring. For electricity meters with sockets at the lower ends, each socket corresponds to a different function of the electricity meter. Therefore, during testing, each socket needs to be connected to the corresponding terminal on the testing equipment through a wire. However, if the wires are connected to the electricity meter sockets and the testing equipment one by one, it is relatively cumbersome, especially when batch testing is required, as a large number of electricity meters need to be tested, and wiring one by one greatly reduces the testing efficiency.
