The invention relates to a method for detecting electric connectors of satellite ground power supply and distribution test equipment, comprising: the same even number of blank points are selected from the electric connectors to be taken as detection points, and the detection points selected from each set of electric connector are not allowed to be completely the same as each other. Then, the detection points are respectively short connected by leads, so that the blank points of the electric connectors can be connected together in series to form a secondary port. The secondary port is connected with a detection circuit provided with an indicator light, a power supply and a detector switch; after the detector switch is closed, a closed loop can be formed only when all connectors are accurately plugged and in good contact, and the indicator light is luminescent at this time. As the numbers of the selected detection points are the blank points which are not used by the connectors, signal points that are already used in the connectors are not influenced; meanwhile, the detection circuit can provide an independent power supply and is completely isolated from a signal circuit of power supply and distribution equipment. The method can effectively improve the safety and the reliability of implementation of satellite integrative test.
