Abstract

The invention provides a constant-voltage output structural part which comprises a protecting plate, a constant-voltage plate, an output terminal and an insulating elastic gasket and further comprises a rechargeable battery using the constant-voltage output structural part, wherein a central hole is formed in the insulating elastic gasket; a convex part is arranged on the edge of the central hole; a battery cell is arranged inside a shell; a stamping notch is formed in the opening end of the shell; the constant-voltage output structural part is sealed by the opening end of the shell; an anode led-out lug is connected with another end connected with a VDD port of a protecting IC, of a first resistor (R1); a cathode led-out lug of the battery cell is connected with a GND port of the protecting IC; the protecting plate is arranged below the stamping notch on the shell; the insulating elastic gasket and the constant-voltage plate are sequentially arranged above the stamping notch in the shell; a cathode output end on the constant-voltage plate is in close contact with the shell. The rechargeable battery provided by the invention is novel in structure and convenient to manufacture, voltage output can be defined according to demands, and market requirements can be met.

Description

technical field [0001] The invention relates to a constant voltage output structural part and a rechargeable battery using the same. Background technique [0002] With the development of secondary battery technology, the performance of secondary batteries has been rapidly improved, and its cost has also been greatly reduced, especially the high energy density and recyclable characteristics of secondary batteries, so it has been increasingly The wider the application. For example, rechargeable lithium-ion batteries in secondary batteries have become the main power supply batteries for mobile phones, notebook computers, and cameras, and in many traditional application fields of primary batteries such as remote controls, flashlights, toys, etc., secondary batteries are gradually becoming more and more popular. Primary battery replacement. [0003] However, compared with the primary battery, the secondary battery still has many inconveniences in use. The primary battery does ...
