1. Technical Field
This disclosure relates to shielding assemblies and methods for manufacturing the shielding assemblies, particularly to a shielding assembly for portable electronic devices.
2. Description of Related Art
A typical portable electronic device, such as a mobile phone, generally includes a printed circuit board with one or more electrical components and a shielding assembly mounted to the printed circuit board to shield the electrical components from atmospheric EMI. The shielding assembly generally includes a frame and a cover. To mount the cover to the frame, the cover is typically welded to the frame by some additional device. Thus, to assemble the shielding assembly is complicated and can be expensive.
Therefore, there is a room for improvement in the art.
Many aspects of the embodiments 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 exemplary shielding assembly and method for manufacturing the shielding assembly. Moreover, in the drawings like reference numerals designate corresponding parts throughout the several views. Wherever possible, the same reference numbers are used throughout the drawings to refer to the same or like elements of an embodiment.
Referring to
The cover 20 includes a main panel 21 and a peripheral panel 23 protruding from an edge of the main panel 21. The main panel 21 includes openings 22, retaining elements 221 and rims 222, and the number of the openings 22 is same as the number of the retaining holes 122. Each retaining element 221 surrounds one of the opening 22, and each rim 222 protruding outwardly from a distal end of one of retaining elements 221. Referring to
Referring to
Providing and punching a first metal plate to form a frame 10, which defines retaining holes 122 and retaining grooves 124. Each retaining groove 124 surrounds and communicates with one of the retaining holes 122.
Providing and punching a second metal plate to form a cover 20, which includes openings 22 and retaining elements 221, the number of the openings 22 is same as the number of the retaining holes 122. Each retaining element 221 surrounds one of the openings 22.
Each retaining element 221 passes through one of the retaining holes 122.
Punching distal ends of the retaining elements 221 to form the rims 222 latched with the portions of the frame 10 surrounding the retaining holes 122, in this exemplary embodiment, the rims 222 are latched in the retaining grooves 124.
In this exemplary embodiment, each rim 222 is latched in one of the retaining grooves 124 so the cover 20 can be latched to the frame 10. Thus, the cover 20 does not need to be welded to the frame 10 with an additional device, so the cost of making the shielding assembly 100 can be reduced.
It is to be further understood that even though numerous characteristics and advantages of the exemplary embodiments have been set forth in the foregoing description, together with details of structures and functions of various embodiments, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the exemplary disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
