Aircraft Plug-in Connector Test System for Rapid Fault Detection

The patent applies preliminary action by integrating test functions directly into the plug-in connectors before faults occur. Each connector includes a test signal generator and evaluator that continuously or periodically test the connection status, so when a fault occurs, the location is already identified or quickly detectable, eliminating the need for time-consuming manual fault-finding procedures after the fault occurs.

The patent implements feedback by having each plug-in connector continuously monitor its own connection status and provide this information to a central evaluation device. The test signal generator sends test signals through the connectors, and the evaluator receives feedback signals from each connector to determine connection status, enabling real-time monitoring and immediate fault detection without manual intervention.

The patent applies segmentation by dividing the aircraft cabling system into multiple independent plug-in connector segments, each equipped with its own test signal generator and evaluation capability. This allows each segment to be tested independently, so faults can be localized to specific connectors rather than requiring systematic testing of the entire cabling system, reducing fault-finding complexity despite the modular structure.

The patent implements self-service by enabling each plug-in connector to autonomously perform self-diagnosis through integrated test signal generators and evaluators. Each connector tests its own connection status and provides self-generated test data to the evaluation device, eliminating the need for external manual testing equipment or procedures and simplifying the overall fault-finding process.

The patent replaces the mechanical manual fault-finding system with an automated electrical testing system. Instead of physically detaching and manually measuring connectors, the system uses electrical test signals transmitted through the connectors to automatically detect faults. This substitution maintains measurement precision through electrical testing while dramatically improving maintenance efficiency by eliminating manual disassembly and measurement procedures.

The patent introduces an intermediary automated evaluation device that mediates between the plug-in connectors and the fault-finding process. This intermediary device receives test signals from connectors, evaluates the connection status, and provides fault information, replacing the need for human operators to manually test each connector while maintaining accurate fault detection capabilities.
