Problems solved by technology

In addition, an elastic sheet 64 bent toward the circuit board 61 is provided at the shielding body 63 near the circuit board 61. The front end of the elastic sheet 64 is stuck on the circuit board 61 to prevent the shielding body 63 from moving longitudinally. The position of 64 is provided with a group of shrapnel 65 perpendicular to the side wall of the shielding body 63. When assembled, it contacts the inner wall 68 of the lower end cover 67 and is pressed against the circuit board 61 to prevent the shielding body 63 from moving forward and backward. However, this structure needs to be provided Multiple matching devices, the processing and installation process is more complicated

Embodiment Construction

[0015] Please refer to FIG. 3 and FIG. 4 , the shielding member of the preferred embodiment of the present invention is suitable for portable electronic devices, and this description takes its application in the mobile phone 100 (only partially shown) as an example for illustration. The mobile phone 100 includes an upper casing 10 , a circuit board 20 and a shielding member (not shown). The circuit board 20 is provided with an electronic component 22 and a ground circuit 24 arranged around the electronic component 22 . In addition, two assembly holes 26 are respectively defined near two ends of the circuit board 20 for assembling and connecting the circuit board 20 to the upper casing 10 . The shielding member is used to shield the electronic components 22 of the circuit board 20 from electromagnetic interference.

[0016] The upper casing 10 is a plastic casing, including an upper surface 12 and a lower surface 14, an accommodating cavity 16 is opened on the upper surface 12...

Abstract

This invention discloses one electron shield part, which connects electron shell to protect electron circuit board part, wherein, the shield parts comprise one shield cover composed of top board and folded side board to enclose shield electron parts space; the shield cover is integrated with shell. This invention also discloses one shell part with shield parts.

Description

【Technical field】 [0001] The present invention relates to a shielding component, in particular to a shielding component arranged in an electronic device to shield electronic components. 【Background technique】 [0002] Electromagnetic interference is one of the common problems of electronic equipment. Usually, the circuit will generate electromagnetic waves in the application. This electromagnetic wave will affect the transmission signal and working performance of other electronic components. To reduce this interference, a conductive material can be installed around the electronic components. The shield body, which can eliminate electromagnetic interference. However, in the fixing of this type of shielding body, in the prior art, the shielding body is usually fixed on the circuit board by welding. Please refer to FIG. First place the shielding body 51 around the electronic components to be shielded on the circuit board 52, then solder the shielding body 51 on the circuit boa...
