Embodiment Construction

[0030] Figure 1 to Figure 5 A first embodiment of the present invention is schematically shown. The shielding case in this embodiment has such figure 1 shown on cover 1 as well as figure 2 The frame 2 shown, the frame 2 and the cover 1 are usually made of conductive sheet metal.

[0031] The frame 2 is roughly rectangular or square, and of course other shapes can also be adopted as required. When the frame 2 is placed horizontally on a printed circuit board (not shown), the lower ends of the four vertical side walls 20 of the frame 2 are connected to the printed circuit board so as to enclose electronic devices or circuits to be shielded (not shown). A transverse edge 22 extends from the top of each side wall 20 toward the inside of the frame, and these four transverse edges are sequentially connected to form a whole, thereby defining an opening at the top of the frame. Typically, frame 2 is formed from a single piece of conductive metal. At least one engaging leg 24 ex...

Abstract

The invention relates to a shielding shell, which comprises a framework and a cover. The framework comprises an uprightly extending side wall and a transverse rim horizontally extending inwards from the side wall; the transverse rim defines a top opening of the framework and is provided with a clamping leg horizontally extending outwards; the cover is provided with a cover board for covering the top opening of the framework, and at least one flange extending downwards from the rim of the cover board; and at least one of the flanges has a clamping structure. When the cover is arranged on the framework, the clamping leg of the framework is locked by the clamping structure. The clamping structure can be either a clamping groove or a clamping protrusion.

Description

technical field [0001] The present invention relates to a shielding shell for electromagnetic shielding of electronic devices and / or circuits within an electronic device. In particular, the shielding shell of the present invention is used for a mobile phone, and the shielding shell has a relatively low height. Background technique [0002] Printed circuit boards are now widely used in electronic and communication equipment, and are often used as substrates for mounting electronic components. A printed circuit board generally includes one or more layers of an insulating substrate, and a circuit is formed on the insulating substrate by depositing conductive metal (such as copper) in a predetermined pattern to connect various electronic components mounted or inserted on the printed circuit board layer ( such as semiconductor components). Such circuits include components capable of operating at high radio frequencies (RF). Radio frequencies emitted by these components may int...
