1. Technical Field
The exemplary disclosure generally relates to a fastening structure used in a portable electronic device.
2. Description of Related Art
In assembling electronic devices, many subsidiary pieces need to be secured to a main housing of the electronic device. A typical method uses screws to fasten the subsidiary piece to the main housing. However, because most of the subsidiary pieces are thin and usually made of plastic, and due to the fragile nature of plastic, it is difficult to maintain a tight engagement between the subsidiary pieces and the main housing with screws.
Therefore, there is room for improvement within the art.
Many aspects of the fastening structure 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 fastening structure.
The housing 10 includes a plurality of sidewalls 14 cooperatively defining a cavity 16 for receiving the printed circuit board 20. A plurality of spaced-apart latching portions 60 are formed along the sidewalls 14. Also referring to
The printed circuit board 20 defines a plurality of locking holes 22 at edges thereof for the hooks 64 to extend through.
The metal plate 30 includes a frame 32 to support a display (not shown). A plurality of latching holes 36 is defined at the edges of the metal plate 30 for the hooks 64 to extend through.
The cover 40 includes a main plate 42 and a flange 44 around the main plate 42. The main plate 42 defines a window 46 corresponding to the frame 32. A plurality of positioning pins 70 are formed around the flange 44 corresponding to the latching portions 60.
To assemble the portable electronic device 100, also referring to
It should be understood that the number of the hooks 64 of each latching portion 60 may be reduced to one. The positioning pins 70 are respectively positioned adjacent to the hooks 64 to prevent the hooks 64 from being easily deformed by an outside force.
It is to be understood that even though numerous characteristics and advantages of the present embodiments have been set forth in the foregoing description, together with details of the structures and functions of the 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 disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
