Embodiment Construction

[0043] Next, an exemplary embodiment for carrying out the present invention will be described with reference to the drawings.

[0044] In recent years, as electronic devices have been reduced in size and thickness, metal housings are widely used in order to ensure the structural strength of the electronic devices.

[0045] As will be described later, in the present embodiment, a metal suitable for the case is used as a part of the shield case; therefore, the thickness can be reduced compared with the prior art.

[0046] Figure 5 is a perspective view showing the shielding structure according to the present embodiment, and Figure 6 for the shielding structure along the Figure 5 Cross-sectional front view of line A-A. By the way, Figure 5 The casing 2 (which will be described later) is not shown.

[0047] Such as Figure 6 As shown, the shielding structure of this embodiment includes a housing 2 of an electronic device (the entire electronic device is not shown), a pri...

Abstract

A shield structure of an electronic apparatus is provided. The structure is strong against external noise or electrostatic discharge, excellent in EMC characteristics and ESD characteristics, and can make the electronic apparatus thin without enlarging the plane dimensions thereof while suppressing radiation noise. The shield structure used in an electronic apparatus comprises a housing (2), and an electronic substrate (1) arranged in the housing (2) while having an electronic component (4). At least a surface of the housing (2) directing toward the electronic component (4) is composed of a conductive material. The shield structure further comprises a frame-shaped portion (5) provided on the electronic substrate (1) to surround the electronic component (4), a leaf spring portion (6) provided to project from the upper edge portion of the frame-shaped portion (5) obliquely upward toward the inside of the frame-shaped portion (5), and a shield member (3) composed of a conductive material. The shield member (3) is provided on the electronic substrate (1) and pressed against the leaf spring portion (6) to come into contact with the surface of the housing (2) composed of a conductive material.

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-...
