BACKGROUND OF THE INVENTION1. Field of the Invention
The present invention relates to a shielding structure for a housing, and more particularly, to a housing shielding structure with elastic conductive elements.
2. Description of Related Art
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.
Accordingly, the present invention provides a shielding structure for a housing which is capable of preventing the electromagnetic radiation leakage and easy to install.
The present invention provides a shielding structure for a housing, which comprises a plurality of elastic conductive elements, at least one carrier, and a cover. The plurality of elastic conductive elements is distributed along a periphery of an opening portion of the housing. Each of the elastic conductive elements comprises 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 comprises a conductive layer electrically connected to each of the conductive materials.
According to one embodiment of the present invention, the conductive material comprises a conductive fabric or a conductive metal mesh screen.
According to one embodiment of the present invention, the soft material comprises a foam. In addition, the material of the foam comprises polyester foam resin or acrylic foam resin.
According to one embodiment of the present invention, the housing has a supporting surface and a plurality of slots formed at the periphery of the opening portion, and the at least one carrier comprises a plurality of carriers fixing the elastic conductive elements in the slots, respectively.
According to one embodiment of the present invention, the housing comprises a plurality of rivets formed on an inner surface of the housing, and the at least one carrier comprises a plurality of carriers with the rivets inserting through the carriers to fix the carriers to the inner surface of the housing.
According to one embodiment of the present invention, the conductive layer and each of the conductive material are electrically connected in a face-to-face contact manner.
According to one embodiment of the present invention, the housing, the cover and the elastic conductive elements are closely engaged with one another.
According to one embodiment of the present invention, the elastic conductive elements are strip-shaped.
According to one embodiment of the present invention, the elastic conductive elements are coplanarly arranged along the periphery of the opening portion.
According to one embodiment of the present invention, the elastic conductive elements are slightly higher than the plane at which the opening portion is located.
In view of the foregoing, the housing shielding structure of the present invention can keep the housing, the cover and the elastic conductive elements in a closely engaged state so as to prevent the electromagnetic radiation leakage. In addition, the elastic conductive elements are fixed to the housing by means of the carrier and are received in the slots, thereby preventing the permanent deformation of the elastic conductive elements due to the long time compression and making it easy to install.
In order to make the aforementioned and other features and advantages of the present invention more comprehensible, embodiments accompanied with figures are described in detail below.
Referring to
In the present embodiment, a supporting surface 202 is formed along the periphery of the opening portion C of the housing 200 and a plurality of slots 204 is formed through the supporting surface 202. The slots 204 are, for example, rectangular slots and there is no limitation as to the number and location of the slots 204. The slots 204 can receive the elastic conductive elements 220 (which are strip-shaped), respectively, such that when the cover 240 covers the opening portion C, a conductive layer 242 (for example, aluminum foil) of the cover 240 may be electrically connected to each of the elastic conductive elements 220 to prevent the electromagnetic radiation leakage. In addition, the cover 240 may be fastened to the housing 200 by a screw (not shown) threaded into a screw hole 206 of the housing 200.

As shown in
In summary, the housing shielding structure of the present invention can keep the housing, the cover and the elastic conductive elements in a closely engaged state so as to prevent the electromagnetic radiation leakage. In addition, the elastic conductive elements are fixed to the housing by means of the carrier and are received in the slots, thereby preventing the permanent deformation of the elastic conductive elements due to the long time compression and making it easy to install.
It will be apparent to those skilled in the art that various modifications and variations can be made to the structure of the present invention without departing from the scope or spirit of the invention. In view of the foregoing, it is intended that the present invention cover modifications and variations of this invention provided they fall within the scope of the following claims and their equivalents.
