Abstract
Description
Technical Field
[0001] This invention relates to the field of power supply technology, specifically to an automatic plug-in / plug-out connection device for power and low voltage. Background Technology
[0002] The current aerospace assembly stage demands stringent requirements for the precision, efficiency, and safety of high-voltage and low-voltage connections. These connections rely on manual plugging and unplugging, requiring precise interface alignment during assembly. This is not only inefficient (each connection is time-consuming) but also prone to interface wear due to operational errors. Furthermore, plugging and unplugging in high-voltage circuits carries risks of electric shock and short circuits. Traditional connection devices, often single-function designs, cannot simultaneously meet the demands of coordinating high-voltage and low-voltage connections, necessitating frequent tool changes when adapting to multi-module integration scenarios, thus impacting assembly progress. Moreover, in explosion-proof environments, the weight of explosion-proof plugs and cables makes them difficult for one person to handle, requiring multiple people to work together, which is time-consuming and labor-intensive. Finally, the limited assembly space further complicates the operation for workers. Summary of the Invention

The device improves connection reliability through automated and precise control and is suitable for various complex assembly scenarios and confined operating spaces.
