Patent Application
20170156241
The subject matter herein generally relates to a shielding cover, a shielding cover assembly and an electronic device employing the shielding cover assembly.
Electronic devices normally include radio frequency circuits and shielding covers for preventing electromagnetic Interference. It is general to arrange a blank zone in a circuit board for being latched to the shielding cover. However, the blank zone is a waste of the design size of the circuit board.
Many aspects of the disclosure can be better understood with reference to the following figures. The components in the figures are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the disclosure. Moreover, in the drawings, like reference numerals designate corresponding parts throughout several views.
It will be appreciated that for simplicity and clarity of illustration, where appropriate, reference numerals have been repeated among the different figures to indicate corresponding or analogous elements. In addition, numerous specific details are set forth in order to provide a thorough understanding of the embodiments described herein. However, it will be understood by those of ordinary skill in the art that the embodiments described herein can be practiced without these specific details. In other instances, methods, procedures and components have not been described in detail so as not to obscure the related relevant feature being described. Also, the description is not to be considered as limiting the scope of the embodiments described herein. The drawings are not necessarily to scale and the proportions of certain parts may be exaggerated to better illustrate details and features of the present disclosure.
The term “coupled” is defined as connected, whether directly or indirectly through intervening components, and is not necessarily limited to physical connections. The connection can be such that the objects are permanently connected or releasably connected. The term “comprising,” when utilized, means “including, but not necessarily limited to”; it specifically indicates open-ended inclusion or membership in the so-described combination, group, series and the like.
The first cover 10 is substantially rectangular in shape and includes a first top wall 13 and three first sidewalls 14 substantially and perpendicularly extended from three edges of the first top wall 13. The other edge of the first top wall 13 substantially and perpendicularly extends at least one first latch 11. In at least one embodiment, the first top wall 13 has three first latches 11 extending therefrom, and a recess 12 is formed between every two adjacent latches 11 and between every one latch 11 and one adjacent first sidewall 14 such that four recesses 12 are formed. Each first latch 11 includes a first connecting portion 111 and a first bent portion 112. The first connecting portion 111 is extended from the first top wall 13, the first bent portion 112 is substantially and perpendicularly bent and extended from the first connecting portion 111. A junction of the first top wall 13 and the first sidewalls 14 defines several first grooves 131 for receiving external tools to separate the first cover 13 and the first frame 30.
The second cover 20 is substantially rectangular in shape, and the second cover 20 includes a second top wall 23 and four second sidewalls 24 substantially and perpendicularly extended from peripheral edges of the second top wall 23. One of the second sidewalls 24 corresponding to the first cover 10 includes four second latches 21 and three notches 22, each notch 22 is formed between every two adjacent second latches 21. The second latches 21 correspond to the recesses 12, the notches 22 correspond to the first latches 11. Each second latch 21 includes a second connecting portion 211 and a second bent portion 212. The second connecting portion 211 extends from the second top wall 23, the second bent portion 212 substantially and perpendicularly bends from the second connecting portion 211 and extends perpendicularly with respect to the second connecting portion 211. A junction of the second top wall 23 and the second sidewalls 24 defines several second grooves 231 for receiving external tools to separate the second cover 20 and the second frame 40.
The first frame 30 and the second frame 40 are substantially rectangular frames and aligned to each other. The first frame 30 includes a peripheral wall 31. The second frame 40 includes a front wall 43 corresponding to the first frame 30. The front wall 43 includes a third connecting portion 432 and a third bent portion 434 substantially and perpendicularly extended from the third connecting portion 432. A junction of the third connecting portion 432 and the third bent portion 434 defines several slots 41. In at least one embodiment, the front wall 43 has four supporting portions 42 extending therefrom, and a slot 41 is formed between every two adjacent supporting portions 42 such that three slots 41 are formed.
Referring to
The first cover 10 and the second cover 20 are latched to each other on the first frame 30 and the second frame 40, thereby decreasing a size of a blank zone from the circuit board 50 while the first cover 10 and the second cover 20 are mounted thereon.
It is believed that the 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 scope of the disclosure or sacrificing all of its advantages, the examples hereinbefore described merely being illustrative embodiments of the disclosure.
