Shield structure of electronic apparatus and electronic apparatus equipped with the shield structure

Abstract

There is provided a shielding structure which can suppress radiation noise for an electronic device, which is resistive against external noise and electrostatic discharge, which has a sufficient EMC characteristic and a sufficient ESD characteristic, and which is capable of reducing the thickness of the electronic device without increasing its size in the plan view. Shielding structure for use in an electronic device comprising a housing 2 and an electronic substrate 1 which is arranged in the housing 2 and which includes electronic parts 4, wherein the housing 2 includes at least a surface facing the electronic parts 4, the surface being made of an electrically conductive substance.; There is disposed a shielding member 3 made of electrically conductive material comprising a frame-shaped section 5 disposed on the printed board 1 to surround a periphery of the electronic parts 4 and a leaf spring section 6 disposed to project from an upper-edge section of the frame-shaped section 5 toward the inside of the frame-shaped section 5 and upwardly in an inclined direction. The shielding member 3 is disposed on the electronic substrate 1, and the surface made of an electrically conductive substance of the housing 2 pushes the leaf spring section 6 to be brought into contact therewith.

Description

technical field [0001] The present invention relates to a shielding structure, a shielding element, and a substantially small-sized electronic device comprising the shielding structure, the shielding element. Background technique [0002] Generally, with electronic devices, there is a case where it is necessary to suppress electromagnetic noise from electronic parts included in the electronic device to external devices, and conversely, by suppressing electrostatic discharge noise and influence from external devices to electronic devices. Ensure adequate electromagnetic compatibility (EMC) characteristics and adequate electrostatic discharge (ESD) characteristics. [0003] In order to ensure sufficient EMC characteristics and sufficient ESD characteristics, a shielding structure is an effective means. [0004] figure 1 is a perspective view showing the shielding structure of the first conventional example, and figure 2 for along figure 1 A cross-sectional view of line A-...
