1. Technical Field
The present disclosure relates to electronic devices, particularly to an electronic device with a plurality of conductive resilient sheets for electromagnetic interference (EMI) shielding.
2. Description of Related Art
In the enclosure of a typical electronic device, there are many kinds of electronic components, such as central processing units and accelerated chips, mounted in a circuit board of the enclosure. The electronic components may emit electromagnetic radiation when operating, such that electromagnetic interference between the electronic components occurs. Some of the electronic components in the enclosure may work abnormally due to EMI. To decrease or overcome the EMI of the enclosure, a conductive resilient sheet is provided to connect the circuit board of an electronic device with the housing. The conductive resilient sheet can reduce or even stop EMI that is produced by the circuit board effectively.
However, poor contact of the conductive resilient sheet and the housing often occurs when an external force shakes the electronic device.
Therefore, there is room for improvement in the art.
Many aspects of the disclosure can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the electronic device. Moreover, in the drawings like reference numerals designate corresponding parts throughout the several views. Wherever possible, the same reference numerals are used throughout the drawings to refer to the same or like elements of an embodiment.
Referring to
The supporting member 12 can be a substantially elongated rectangular sheet. The supporting member 12 includes a base portion 120 and four side walls 121, 122, 123, 124 extending upward from four edges of the base portion 120. The base portion 120 and the four side walls 121, 122, 123, 124 cooperatively define a cavity 125 to receive the circuit board 13. The side walls 122, 124 are opposite to each other. Each of the side walls 122, 124 forms an engaging portion 1220 extending out from a top end of the side walls 122, 124. Each of the engaging portions 1220 defines a locking hole 1222 and a latching hole 1224 aligned separate from the locking hole 1222 adjacent to a top of each of the engaging portions 1220.
The bottom cover 14 includes a bottom plate 142, a first side frame 144 and a second side frame 146 extending upward from two opposite edges of the bottom plate 142. Each of the side frames 144, 146 forms a latching hook 1440 corresponding to the latching holes 1224 of the two engaging portions 1220. Each of the latching hooks 1440 is formed at an end of each side frames 144, 146 adjacent to the supporting member 12. Each side frames 144, 146 further defines a positioning hole 1442 corresponding to one locking hole 1222 adjacent to and apart from the latching hook 1440.
Referring to
During the assembly of the electronic device 100, the circuit board 13 is fixed in the cavity 125, and the sheet 16 is fixed on the circuit board 13 with two screws extending through the corresponding fixing holes 1622. The bottom cover 14 moves toward the supporting member 12 until the latching hooks 1440 engage with the latching holes 1224 correspondingly. Two bolts (not shown) extend through the locking holes 1222, 1442 correspondingly to lock the supporting member 12 to the bottom cover 14.
Referring to
It is believed that the present embodiments and their advantages will be understood from the foregoing description, and it will be apparent that various changes may be made thereto without departing from the spirit and scope of the embodiments or sacrificing all of its material advantages.
