Description

Technical Field

[0001] This utility model relates to the field of aviation plug technology, and in particular to a waterproof and dustproof aviation plug structure with a cavity. Background Technology

[0002] Existing industrial aviation connectors are mostly of a split structure, with a waterproof rating typically of IP44. They only provide basic plug-to-power functionality, lacking current and voltage detection and identification capabilities for the load devices. Generally, aviation connectors are used for powering large load equipment or machine tools, requiring the installation of various levels of distribution boxes on-site. These distribution boxes supply power to the load equipment or tools via the aviation connectors, which are directly connected to the distribution boxes. Calculating the power consumption of the load equipment or tools requires manual checking of their respective power distribution meters, making it impossible to obtain real-time information on the current power consumption of each load equipment or machine tool. Without knowing the power consumption of these load devices or tools, it is impossible to keep track of their frequency of use, current fluctuations, and current trends, thus hindering proper maintenance and upkeep of the equipment and tools, and preventing the review of relevant usage records. To obtain information on the electrical connections, power consumption, and identification of the load devices or tools, the researchers temporarily installed a communication module (intelligent circuit control board) at the power supply point of the aviation socket to provide feedback on the electrical connection status. After the aviation plug is inserted into the distribution box, power can be supplied to the communication module (intelligent circuit control board), thereby enabling the acquisition of information on the electrical connections, power consumption, and identification of the load devices or tools.

[0003] In order to better integrate the communication module with the aviation plug, a new type of aviation plug structure needs to be developed, which can provide waterproof and dustproof functions, and can also build a communication module (intelligent circuit control board) to realize the current and voltage detection and identification information of the plug load product.

[0004] Therefore, it is necessary to propose a waterproof and dustproof aviation plug structure with a cavity to seal and house the communication module, so that the aviation plug can contain items and be waterproof and dustproof. Utility Model Content

[0026] Please refer to Figures 1-3 This utility model proposes a waterproof and dustproof aviation plug structure with a cavity, including a plug end 1 and a protective shell 2. The plug end 1 adopts a one-time injection molding process to achieve an integrated waterproof design. One end of the plug end 1 is fixed and sealed to one end of the protective shell 2. The protective shell 2 has a cavity 21 for accommodating items. The other end of the protective shell 2 is a conventional structure that wraps around the cable for a sealed connection.

[0027] In this embodiment, a receiving cavity 21 is provided inside the protective shell 2. The receiving cavity 21 can hold the communication module and the cable connecting the plug-in terminal 1. After the communication module and the cable are placed into the receiving cavity 21, one end of the plug-in terminal 1 is fixedly and sealed to one end of the protective shell 2. At this time, the communication module and the cable have a waterproof and dustproof effect inside the receiving cavity 21. After the aviation plug is connected to the power distribution box, the communication module can be powered through the plug-in terminal 1 and communicate with the power distribution box, thereby obtaining the electrical connection, power consumption and identity information of the load equipment or tools.

[0028] In summary, this waterproof and dustproof aviation plug structure with a cavity can effectively seal and accommodate the communication module, allowing the aviation plug to house items while remaining waterproof and dustproof.
