The utility model discloses a misplug-proof connecting plug for a high-voltage combined metering box. The high-voltage combined metering box comprises a socket with a conductive column arranged on thehigh-voltage combined metering box, an outgoing line of the high-voltage combined metering box is connected with the conductive column; the test junction box is connected with a plug with a jack through a cable; the cable core is connected into the jack; outgoing lines of the high-voltage combined metering box comprise an A voltage outgoing line, a B voltage outgoing line, a C voltage outgoing line, an aS1 current outgoing line, an aS2 current outgoing line, a cS1 current outgoing line and a cS2 current outgoing line. The cable comprises three voltage cables A, B and C and four current cablesaS1, aS2, cS1 and cS2. Each outgoing line is connected with one conductive column; an identifier corresponding to the outgoing line is marked near the conductive column; wherein each cable core is connected into a jack, an id
