Description
Technical Field

Background
EWIS refers to various wires, termination devices, wiring devices, or combinations thereof installed in any area of an aircraft for transmitting electrical power between two or more termination points. The EWIS design is wide, large and complete in professional scope, and any small problem or fault can lead the whole body to be dragged, so that the normal work of the whole system is influenced. EWIS has become the most complex, demanding, longest design cycle specialty in aircraft development.
The electrical connector serves as a basic and important component of the EWIS system, and plays a role in connecting lines on the machine, conducting current and electrical signals. The permanent and stable reliable connection of the electric connector is a necessary prerequisite for ensuring the safe and reliable operation of the aviation system, and the case that the whole system cannot work normally due to the fault of the electric connector is not rare.
According to the statistics of the American air force safety center on the faults of the airplane caused by various components related to the electronic and electric system of the airplane during the period from 1989 to 1999, the faults caused by the connector account for 14 percent.

In combination with feedback from the outfield of a large-sized aircraft, common failure modes of the electrical connector during use are poor contact and poor sealing caused by the machining and manufacturing reasons of the connector, loose disconnection and poor contact of the electrical connector caused by environmental reasons, disconnection and connection errors caused by human factors, and the like.
Aiming at the problems of loosening, breaking and poor contact of the electric connector, the connector adopted in the current model is a quick-release electric connector with a locking function, but the connector still has the possibility of loosening under certain strong vibration environment, and the remedy measures aiming at the problems are as follows: 1. the electric connector with the fuse hole is used, and the fuse is used for fusing after the connector is connected in place, so that the maintainability index of the airplane is reduced, the quick-release connector loses the quick-release function, and meanwhile, the problems of disconnection and connection errors caused by human reasons cannot be solved by adopting a fuse-making measure; 2. the crew increases the frequency of inspecting the connectors in a manner that artificially increases the workload of the crew while making inspection difficult for locations that are not easily accessible.
Therefore, how to efficiently and quickly troubleshoot the connector failure is a problem to be solved.
