AI Technical Summary

Technical Problem

Electromagnetic compatibility problems caused by nonlinear effects in electronic devices, especially in folding screen mobile phones and mobile phones with lifting camera modules, the nonlinear effect of the nonstable contact area leads to electromagnetic compatibility problems.

Method used

By introducing a conductive dielectric into the electronic device, a second current path is formed to shunt the coupling current in the first current path, eliminating or weakening the nonlinear effect. The conductive dielectric may cover the surface of the structural member or be electrically connected to the structural member through a conductive filler to form a low impedance second current path.

Benefits of technology

It effectively solves the electromagnetic compatibility problem caused by nonlinear effects in electronic devices. By shunting the current, the nonlinear effects are reduced and the electromagnetic compatibility of the equipment is improved.

Abstract

Provided in the embodiments of the present application are an electromagnetic protection structure and an electronic device. The electromagnetic protection structure comprises: a first structural member, which comprises a radio frequency source; a second structural member, wherein a first current path is coupled between the second structural member and the first structural member, a nonlinear region is included in the first current path, and when a coupling current of the radio frequency source passes through the nonlinear region, the nonlinear region produces a nonlinear effect; and a conductive medium, which is electrically connected to the first structural member and the second structural member, so as to form a second current path between the second structural member and the first structural member, such that at least part of the coupling current of the radio frequency source flows from the first structural member to the second structural member, passing through the second current path. In the embodiments of the present application, a second current path formed by a conductive medium can perform current division on a first current path, so as to eliminate or weaken a nonlinear effect on the first current path, thereby solving the electromagnetic compatibility problem of an electronic device caused by the nonlinear effect.
