The invention provides a
constant voltage output structural member. The
constant voltage output structural member comprises a protection plate, a
constant voltage plate, an output terminal and an insulation elastic
gasket, wherein a central hole is formed in the insulation elastic
gasket, and a protruding part is arranged at the edge of the central hole. The constant
voltage output structural member also comprises a rechargeable battery employing the constant
voltage output structural member provided by the invention, wherein a battery core is arranged in a shell, a
punching groove is formed in an opening end of the shell, the constant
voltage output structural member is further sealed at the opening end of the shell, a positive
electrode leading-out tab of the battery core is connected to the other end which a first
resistor 9R1) and a VDD port of a protection
integrated circuit (IC) are connected, a negative
electrode leading-out tab of the battery core is connected to a GND port of the protection IC, the protection plate is arranged blew a groove position of the
punching groove in the shell, the insulation elastic
gasket and the constant voltage plate are sequentially arranged above the groove position of the
punching groove in the shell, and a negative
electrode output end of the constant voltage plate is in
close contact with the shell. The rechargeable battery is novel in structure and is convenient to fabricate, the voltage output can be limited according to demands, and the market demand can be satisfied.
