The waterproof multi-national plug interchangeable power adapter consists of a power supply main body and a multi-national plug. It can be freely disassembled and assembled through a special connection locking structure. It not only meets the waterproof IP22 standard for household medical power supplies, but also extends the global versatility of the power supply main body to the greatest extent. The main body of the power supply is designed with a special-shaped connection deep groove. The top of the special-shaped deep groove is designed with a closed waterproof enclosure. Two contact conductive copper pins are symmetrically placed in the geometric center of the special-shaped deep groove. A lock is cleverly hidden in the middle of the special-shaped deep groove. The sliding button structure is used to realize the free plug-in locking function between the plug and the power supply body; the plug contains connection bumps that match the power supply body and required pins, and the bottom of the special-shaped connection bumps is designed with an annular waterproof recess that matches the waterproof enclosure. The groove realizes current transmission through the contact between the three-claw metal contact spring hidden inside the bump and the conductive copper pin. When the plug is inserted into the main body of the power supply, the three-claw metal contact spring contacts the conductive copper pin in an annular surrounding state.

The latest generation of multi-national conversion power supply has flexible and reliable power pin removal and assembly movements, convenient use and good user experience. It skillfully realizes the waterproof requirements of the medical power supply industry and takes the lead in breaking through the waterproof requirements of multi-national replaceable power supplies in the power supply industry. The complete power supply achieves a true IP22 waterproof level, leading the technological trend in the household medical power supply industry!
