Aviation wire harness continuity test--aircraft wire harness tester

The current wiring harness continuity test uses a large number of test cables, resulting in a series of problems such as low efficiency, high cost, and poor compatibility. Aigtek proposed a testing method that combines software and hardware to test aircraft wiring harness continuity testing.

With the continuous development of my country's aviation industry, its safety management level is also constantly improving. The quality of aviation cables plays a very important role in safety testing. Aviation cables are neural networks that connect aircraft electrical, control and other systems and provide power, control signals and data information to various parts of the aircraft. They play a very important role. The manufacturing quality of aviation cables has a very important impact on the quality of aircraft. Its performance directly affects the safety of aircraft flight. Cable inspection, as a key link to ensure the quality of aviation cables, has been highly valued by various aviation manufacturing companies. Once there is a problem with the cable, it may endanger the flight safety of the aircraft. Therefore, it is very necessary to repair the aircraft cable.

After the aircraft cables are made, a comprehensive test is conducted on the correctness of the cable wiring, on-off status, and cable insulation performance to determine whether the connections are correct and whether there are disconnections (open circuits), cross-wiring (misconnections), short circuits, and The insulation is damaged to ensure that the aircraft systems can function normally after their wiring is completed. Aviation electrical systems require high reliability, high integration, and high portability, so cables are generally very thin; and due to the space limitations of the aircraft fuselage, electrical system wiring is generally concentrated in the small space of the fuselage wall, and most wires are bent and shuttled between Between the metal structures, the aircraft walls are almost covered with wires; and there are many types of wires, including power wires, signal wires, control wires, AC power wires, DC power wires, high-frequency wires, low-frequency wires, single power wires, and three power wires. Scores are mixed. Due to the structural limitations of the aircraft itself, and the wiring in the fuselage space is bent a lot, many wires are bundled into a bundle. When the aircraft is flying, long-term vibration causes the cables and the shareholder frame to rub against each other, damaging the insulation layer, and even causing the cable conductor to break. This requires comprehensive testing of the conduction status of aviation cables and the insulation performance of the cables to ensure the safety and reliability of the aviation electrical system.
