AI Technical Summary
The existing sealing structure of the power interface of intelligent machines is prone to aging and cannot adapt to complex environments. Furthermore, its waterproof performance is insufficient under conditions of frequent plugging and unplugging and vibration, posing a risk of moisture infiltration.
The system employs a multi-layer composite material elastic sleeve and compression ring to achieve a double seal. Combined with the adjustment components of the slide rail and protective cover, it is equipped with a water-absorbing pad, drainage holes and heat sink. Magnetic sheets are used to enhance the closure stability, and a buffer pad reduces impact. The main shell structure is optimized to improve waterproof performance and reliability.
It significantly improves the waterproof performance and reliability of the power interface, extends the service life of the sealing components, ensures the normal operation of the equipment in humid, rainy and high-temperature environments, and simplifies the operation process.
