AI Technical Summary

Benefits of technology

The present invention provides a shielding structure for a housing that prevents electromagnetic radiation leakage and is easy to install. The structure includes a plurality of elastic conductive elements distributed along the periphery of an opening portion of the housing, at least one carrier that fixes the elastic conductive elements to the periphery of the opening portion, and a cover that covers the opening portion and is electrically connected to each of the conductive materials. The elastic conductive elements can be made of a soft material, such as foam, and can be fixed in slots or rivets on the housing. The cover and the elastic conductive elements are closely engaged with each other, and the elastic conductive elements are strip-shaped or coplanarly arranged along the periphery of the opening portion. The shielding structure prevents the permanent deformation of the elastic conductive elements and ensures the housing, the cover, and the elastic conductive elements are in a closely engaged state to prevent electromagnetic radiation leakage.

Problems solved by technology

However, the above-mentioned fabrication process must involve the additional step of soldering the metal elastic tab 123 to a pad 122 of the circuit board 12, which not only increases the material cost but also increases the fabrication cost.

Embodiment Construction

[0026]FIG. 3A is a top view of a shielding structure for a housing according to one embodiment of the present invention. FIG. 3B is a bottom view of the housing shielding structure of FIG. 3A. FIG. 3C is a cross-sectional view of the housing shielding structure of FIG. 3A.

[0027]Referring to FIGS. 3A to 3C, the housing shielding structure 210 includes a plurality of elastic conductive elements 220, a plurality of carriers 230, and a cover 240. These elastic conductive elements 220 are distributed along a periphery of an opening portion C of a housing 200. Each elastic conductive element 220 includes a soft material 222 and a conductive material 224 wrapping the soft material 222. The conductive material 224 is, for example, a conductive fabric, a metal mesh screen, or another conductive material. The soft material 222 may be a foam or compressible porous material. The material of the foam is, for example, polyester foam resin or acrylic foam resin. Once the conductive material 224 wr...

Abstract

A shielding structure for a housing includes a number of elastic conductive elements, at least one carrier, and a cover. The elastic conductive elements are distributed along a periphery of an opening portion of the housing. Each elastic conductive element includes a soft material and a conductive material wrapping the soft material. The at least one carrier fixes the elastic conductive elements to the periphery of the opening portion. The cover covers the opening portion and has a conductive layer electrically connected to each conductive material.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims the priority benefit of Taiwan application serial no. 98123231, filed on Jul. 9, 2009. The entirety of the above-mentioned patent application is hereby incorporated by reference herein and made a part of specification.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to a shielding structure for a housing, and more particularly, to a housing shielding structure with elastic conductive elements.[0004]2. Description of Related Art[0005]In electronic products such as notebook computers, cell phones, displays or the like, a conductive layer is usually formed by plating at a seam between a housing and a cover in order to prevent leakage of electromagnetic radiation from between an opening portion of the housing and the cover.[0006]FIG. 1 illustrates a cross-sectional view of a conventional metal shielding structure. Referring to FIG. 1, the shielding structure 100 includes a co...
