Abstract

The utility model discloses an improved button cell tank structure, which mainly comprised a circuit board, a fixed ring and a cover body, wherein the circuit board is provided with a central contact point which is connected with an electronic element and a welding point which is circularly arranged at the contact point. The fixed ring is positioned at the position of the welding point and is welded on the circuit board, and after a button battery is positioned, the cover body is locked at the fixed ring. Through the conduction of the fixed ring and the contact point, the positive electrode voltage and the negative electrode voltage of the button battery are transmitted to the electronic element. Because the cover body is locked and opened along the fixed ring, the replacement of the button battery is more convenient and quicker.
