Abstract

This application illustrates an electro-static discharge protection structure and an electronic device. One end of the metal partition wall is connected to the metal housing, the other end of the metal partition wall extends in a direction away from the metal housing, to form an end surface at one end away from the metal housing, and a screen module is disposed on a side of the metal partition wall; A continuous conductive layer is disposed between the insulation frame and the screen module; the insulation frame comprises a junction surface, which faces the end face of the metal partition wall; an insulation layer is disposed between the conductive layer and the end surface; and the insulation layer is an insulation layer that can be broken down by static electricity. The electro-static discharge protection structure prevents a problem of RSE and further affecting antenna performance, and prevents secondary discharge.
