Problems solved by technology

[0008] In view of this, the technical problem to be solved by the present invention is to use the design of the conditional conduction path to form a discharge path for electrostatic discharge without greatly increasing the complicated process and product cost, effectively disabling all the static electricity on the conductive shell. The accumulated static charge is conducted to the power ground point of the electronic product

Embodiment Construction

[0032] The invention is aimed at the design of electrostatic discharge protection for electronic devices with conductive shells. In the circuit design, use the grounding point of the power supply of the electronic device to match the electrical characteristics of the electronic components to complete the discharge channel of the electrostatic discharge. In this way, in the normal state where the conductive shell has not yet generated electrostatic discharge, an open circuit is formed between the conductive shell and the ground point of the power supply; and when the conductive shell generates electrostatic discharge, the electrostatic charge accumulated on the conductive shell Venting can then be done via the power ground point.

[0033] In addition, in circuit design, ground points with different functions are usually planned, which can be roughly divided into power ground points and data signal ground points. And because the present invention is to provide electrostatic dis...

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...
