Abstract

The invention provides a built-in constant-voltage protection structural member. An insulation elastic part is arranged on each of the two surfaces of a printed circuit board (PCB), at least one penetrating hole is formed in the insulation elastic part, and the PCB comprises a substrate, a voltage converter, a protective integrated circuit (IC), an inductor, a diode, a first resistor (R1), a second resistor (R2), a third resistor (R3), a first capacitor (C1), a second capacitor (C2), a third capacitor (C3), a fourth capacitor (C4) and a fifth capacitor (C5). The invention also provides a rechargeable battery using the built-in constant-voltage protection structural member arranged between a battery cell and a punching groove position of a 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 is met.

Description

technical field [0001] The invention relates to a built-in constant voltage protection 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 ...
