Battery pack with static discharge protective function and electronic device

Abstract

The invention discloses a battery pack with a static discharge protective function and an electronic device. The electronic device comprises a conductive shell and a circuit board, wherein the circuit board is arranged in the conductive shell, and comprises a power supply earth point and a conditional conducting path; the conditional conducting path further comprises a conductive element and a static discharge element; one end of the conductive element is electrically connected with the conductive shell; and the static discharge element is electrically connected between the other end of the conductive element and the power supply earth point. When the voltage difference between the two ends of the static discharge element satisfies a preset condition, the static discharge element is conducted, otherwise the static discharge element is equivalent to a high-impedance element for the power supply earth point. Moreover, the power supply earth point is electrically connected with a battery, so that a static discharge protection effect is achieved by using the battery.

Description

technical field [0001] The invention relates to a battery pack and electronic device with electrostatic discharge protection function, in particular to a battery pack and electronic device with electrostatic discharge protection function designed by using a conditional conduction path. Background technique [0002] Substances in nature gain or lose electrons through certain processes (such as friction or induction electrification), and this type of charge is called static electricity. When positive charges or negative charges gradually accumulate to generate a potential difference with the surrounding environment, and then transfer between different potentials through a discharge path, it is called Electrostatic Discharge (ESD) phenomenon. The large current generated by this instantaneous discharge will cause permanent damage to electronic components, which will affect the circuit function of the electronic system and make the product operate abnormally. [0003] However, t...
