[0002] A rail meter is a meter used to measure electrical energy consumption, usually installed on the rails of a circuit. It calculates the amount of electrical energy used by measuring current and voltage and displays it on the meter. Figure 8 As shown, it includes an electric meter housing 40, and the electric meter housing 40 includes a housing wiring portion 41 and a housing display portion 42 arranged on the housing wiring portion 41, and the housing wiring holes 43 are horizontally spaced on the housing wiring portion 41. Generally, after we assemble the guide rail type electric meter, we need to use a verification device to verify the connection of the housing wiring holes 43 of the electric meter housing 40. The traditional verification method often adopts a manual sampling method to extract a few guide rail type electric meters from a batch of them so that their housing wiring holes 43 are connected to the verification device one by one for verification. This method is inefficient and cannot be applied to full inspection during large-scale production, so it needs to be improved. Utility Model Content
