1results about How to "Play a shielding role" patented technology

The utility model relates to the technical field of mobile power supply, concretely relates to a mobile power supply. Mobile power supply includes casing, data line, charging interface and main control circuit board, charging interface and data line are installed in casing one end, and main control circuit board is installed in casing and is located in the one end close to charging interface and data line. Main control circuit board includes AC component region and DC component region, and AC component region is installed with AC component, and DC component region is installed with DC component, is provided with the isolation board on main control circuit board, and the isolation board isolates AC component region and DC component region. The isolation board can play the shielding effect, and the magnetic field produced by AC component and its circuit is blocked to the influence of DC component and its circuit, thereby guaranteeing that the direct current output by DC component and its circuit is more stable, reduces the bad influence to other components using direct current in mobile power supply, such as avoiding electronic equipment signal transmission error, performance instability and so on.
