Research on Automatic Measurement of Aerospace Electrical Connector Wire

Abstract

AbstractAerospace cable network products have the characteristics of large cable network, difficult transportation, many kinds and types of cable plugs, small batch, complex cable signal connection, etc. in the early stage, the loose wire labeling of low-frequency cable connectors mainly relies on manual operation, using common tools such as conductors and multi-meter for inspection, and the test operator generally needs at least two or more people, According to the design drawings and the cable wiring table, the test is carried out one by one. The test time is long, and it is easy to make people tired during the inspection process, resulting in cable detection errors. Therefore, the loose wire conduction number of aerospace cable connector is a major reason for hindering the production efficiency of cable network, This paper designs the scheme of automatic number measurement for different cable connectors, compares and optimizes the design ideas, outputs the required binary code through the cascade of multiple encoders, completes the research on the principle of wire number measurement, realizes the signal conversion and display through the single chip microcomputer, and then transmits the tested wire label content to the label printer through the communication agreement, The label marking machine prints out the label from the test results of the wire number measuring tooling, which makes the label printing convenient for use, improves the efficiency of operator’s whole wire bundle labeling, and ensures the accuracy of wire bundle labeling.
