AI Technical Summary
The conductive contacts of existing power adapters are exposed on the outside, making them susceptible to damage from falling. Furthermore, prolonged exposure to air can lead to dust accumulation or rust, affecting stable operation.
A power adapter with a protective component is designed, including a housing, a movable block, a connecting rod, a resilient component, and a rigid protective cover. By sliding and rotating the resilient component, the protective component covers the plug when not in use, preventing it from being exposed to the air.
It effectively protects the connector from damage, extends its service life, and maintains the stability and aesthetics of the adapter.
