Abstract
A power supply device includes a main body defining a receiving cavity which has an opening, a battery and a metallic plate both disposed in the receiving cavity, a metallic ring mounted around the opening, and a cover disposed at the opening. The metallic ring is positioned between the cover and the main body and heated by the high-frequency heating for fusion of the cover and the main body to seal up the battery in the receiving cavity. The metallic plate is located between the battery and acting parts by the high-frequency heating to separate the energy of the high-frequency heating from the battery. The main body or the cover are provided with a connecting element of which one end is exposed in the receiving cavity to electrically connect the battery and the other end is exposed outside the power supply device to electrically connect an external electronic product.
