Abstract

The invention relates to the technical field of circuits, in particular to a circuit protection structure of a power management chip and a working method thereof, including a circuit board, a push switch body mounted on the circuit board, and a mounting device for easy assembly provided on the circuit board The circuit board is provided with a rebound component that assists the rebound of the push switch body, the circuit board is provided with a heat dissipation component that dissipates heat from the circuit board, and the heat dissipation component is provided with a preload for the mounting component. The purpose of the present invention is to provide a circuit protection structure for a power management chip, which can flexibly adjust the angle of the circuit board, avoid the circuit board from being unable to be assembled with the casing due to the angle of the circuit board, and at the same time can help the push switch body. Rebound after pressing, avoid pressing the switch body for a long time, and the rebound performance will deteriorate and cannot fully rebound. In addition, the circuit board can be dissipated to avoid a large amount of heat generated by the circuit board, which will affect the normal operation of the circuit board.

Description

technical field

[0001] The invention relates to the technical field of circuits, in particular to a circuit protection structure of a power management chip and a working method thereof. Background technique

[0002] The power management device includes a circuit board and a power management chip. When assembling the power management device, the power management chip needs to be installed on the circuit board. At the same time, a switch will be installed on the circuit, and then the casing will be installed on the circuit board. Most of the current switches are pressed back. However, after long-term use, the resilience performance of the push switch is significantly reduced. At the same time, when the circuit board is assembled with the casing, the problem that the circuit board cannot be assembled due to the angle problem and the casing is often encountered. SUMMARY OF THE INVENTION

[0003] The purpose of the present invention is to provide a circuit protection structure ...
