Problems solved by technology

[0004] However, in the known technology, after the shielding cover 13 covers the electronic components on the circuit board 11, it is not easy to disassemble, so that if the electronic components are to be repaired or replaced in the future, it is necessary to spend a lot of man-hours to remove the shielding cover 13. Quite a waste of manpower cost
Furthermore, the electronic components close to the inner edge of the bracket 12 have limited maneuvering space for operation, which also causes problems that are not easy to maintain.
In addition, in terms of material cost, if the shape of the circuit board 11 or the placement of electronic components is changed, the bracket 12 must also be remade, which is not easy to mass-produce and costly

Embodiment Construction

[0020] The screening device according to the preferred embodiment of the present invention will be described below with reference to the relevant drawings, wherein the same elements will be described with the same reference symbols.

[0021] Figure 2A and Figure 2B They are respectively an assembled view and an exploded view of a shielding device according to the first embodiment of the present invention. Please refer to Figure 2A and Figure 2B As shown, the shielding device 2 is applied to a circuit board 21, which is preferably a printed circuit board. The shielding device 2 includes a shielding cover 22 and a plurality of buckles 23 .

[0022] The shielding cover 22 has a plurality of perforations 221, but the number of the perforations 221 is not particularly limited, depending on the shape of the circuit board 21 or the placement of the electronic components, so as to securely fix the shielding cover 22 at the desired covering position. And it is the principle to...

Abstract

The invention provides a cloaking device applied to a circuit board. The cloaking device comprises a cloaking cover body and a plurality of fastening pieces, wherein the cloaking cover body covers the circuit board and is provided with a plurality of through holes, each fastening piece is provided with an elastic part and a fixed part, the fixed parts are fixedly arranged on the circuit board, and the elastic parts deform so as to pass through the corresponding through holes and recover so as to fix the cloaking cover on the circuit board. The cloaking device provided by the invention is beneficial to replacement or maintenance of electronic elements in the future and is good for the production standardization of material and parts.

Description

technical field [0001] The invention relates to a shielding device, in particular to a shielding device for preventing electromagnetic interference. Background technique [0002] Electronic components will generate a certain degree of electromagnetic field during operation. The electromagnetic fields generated by electronic components may interfere with each other and block each other. This is the so-called Electro-Magnetic Interference (EMI), which will cause electronic components to malfunction and affect signal transmission. the quality of. At present, the methods used to prevent electromagnetic interference on the market include water electroplating, electroplating, vacuum sputtering and spraying conductive paint, or directly use the shielding effect of metal materials, such as stainless steel, aluminum foil, iron parts or aluminum-magnesium alloys. Among them, the method of directly covering with metal parts is the most commonly used because of its low cost and complia...
