Description

Technical Field

[0001] This utility model relates to the field of auxiliary structure technology for parameter acquisition devices, and in particular to a waterproof structure for the data interface of a flight parameter acquisition device. Background Technology

[0002] The flight parameter acquisition unit (FPI) is an airborne electronic device specifically designed for real-time acquisition, conditioning, and processing of aircraft flight status information and data from various critical systems. It features multiple signal acquisition interfaces, such as analog, discrete, digital, and bus signals, and connects to the flight data recorder to store the acquired data. After ground processing, this data can provide a basis for flight training and assessment, aircraft fault diagnosis and maintenance, and flight accident investigation. The connectors of the flight parameter acquisition unit need to be waterproof because aircraft may encounter harsh environments such as humidity and rain during flight. If the connectors are not waterproof, moisture can enter through gaps, potentially causing electrical instability or even equipment malfunction, affecting flight safety. Therefore, it is necessary to add a waterproof structure to improve waterproofing, ensuring the parameter acquisition unit can operate stably and reliably in complex environments, providing strong protection for flight safety. However, existing waterproof structures are inconvenient to disassemble, making it difficult for users to remove the data connectors. Furthermore, existing waterproof structures still have gaps, and over time, moisture from the environment can accumulate inside the waterproof structure due to temperature changes, potentially causing equipment malfunction. Therefore, this utility model is proposed. Utility Model Content
