Embodiment

[0024] Such as figure 2 Shown is the circuit diagram of the detection circuit when using the method of the present invention to detect three aviation connectors. In the figure, aviation connectors I, II and III are 50-core Y2-50 electrical connectors, which are composed of plugs and sockets; I-ZJ, II-ZJ and III-ZJ are aviation connectors I and II respectively. The socket ends of and III are fixed on the power supply and distribution equipment; I-TK, II-TK and III-TK are the plug ends of aviation connectors I, II and III respectively, which are connected to the cables respectively; here it is assumed that aviation Points 1, 2 and 3 of connectors I, II and III are unused empty points.

[0025] First, select an unused empty point as the detection point of the aviation connector, and the empty points selected by the three plugs cannot be exactly the same. Here, "12" is selected for aviation connector I, "13" is selected for aviation connector II, and "23" is selected for aviati...

Abstract

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.

Description

technical field [0001] The invention relates to an anti-misplug detection method for an electrical connector widely used in satellite ground power supply and distribution test equipment in the aerospace field. Background technique [0002] The satellite ground power supply and distribution test equipment is an important part of the satellite comprehensive test. The test equipment uses a large number of bayonet type circular sealed electrical connectors of the same type. The appearance of each electrical connector is exactly the same, and it is easy to The problem of mismating electrical connectors. [0003] At present, satellite ground power supply and distribution test equipment adopts the method of pasting labels on electrical connectors to avoid misplugging. However, due to the large number of electrical connectors and the identical appearance, it is difficult to avoid misplugging of electrical connectors only by visually observing the labels. In addition, the current pa...
