DETAILED DESCRIPTION

Referring to FIG. 1, an embodiment of an electronic device includes a main body 20, a panel 10, and four panel fixtures. Each panel fixture includes a button 310 and a fastener 320.

The main body 20 defines a quadrate through hole 201. Four long fixing holes 203 are defined in four corners of the main body 20 around the through hole 201. A lengthways direction of each fixing hole 203 is angled relative to lengthways directions of its neighboring fixing holes 203. In the illustrated embodiment, the lengthways direction of each fixing hole 203 is perpendicular to the lengthways directions of its neighboring fixing holes 203.

The panel 10 includes a quad rate main part 100 and a margin portion 101 extending from edges of the main part 100. The margin portion 101 defines four holes 102 in four corners of the margin portion 101. The panel 10 may be a LCD panel or a keypad.

Referring to FIG. 2, the button 310 of each panel fixture is generally T-shaped and includes two coaxial cylindrical portions 3102, 3104. A diameter of the cylinder portion 3102 is greater than a diameter of the cylinder portion 3104. The button 310 defines a through hole 311 along an axial direction. The through hole 311 includes a cuboid first part 3111 defined in the cylinder portion 3104, and a cylindrical second part 3113 defined in the cylinder portion 3102. The cuboid first part 3111 has a rectangular cross-section. The cylindrical second part 3113 has a circular cross-section whose diameter is smaller than a longest length, while larger than a shortest length of the rectangular cross-section of the first part 3111. As a result, a stop portion 3112 is formed on a wall of the first part 3111 at the intersection of the first part 3111 and the second part 3113.

The fastener 320 includes a cylindrical body 321, a block 322 perpendicularly connected to a first end of the body 321, and a taper-shaped elastic head 325 connected to a second end of the body 321. A diameter of the largest portion of the head 325 is greater than the diameter of the second part 3113 of the through hole 311. Two opposite flat surfaces 326 parallel to an axial direction of the body 321 are formed on a circumference of the head 325.

Referring to FIGS. 3 through 5, in assembling the panel fixtures to the panel 10, the head 325 of each fastener 320 is elastically compressed to pass through the hole 102 of the panel 10 from a back of the panel 10 and the second part 3113 of the through hole 311. After entering the first part 3111 of the through hole 311, the head 325 restores to resist against an inner wall of the first part 3111. The fastener 320 is fixed to the button 310 and will not separate from the button 310, because the stop portion 3112 of the button 310 prevents the head 325 from passing through the second part 3113, and the flat surfaces 326 are resisting against walls of the first part 3111. In addition, the block 322 prevents the fastener 320 from passing through towards the first part 3111.

The panel 10 is attached to the main body 20 by aligning the blocks 322 of the fasteners 320 with the fixing holes 203 of the main body 20. The buttons 310 are rotated to adjust the angle of the lengthways directions of the blocks 322 until the lengthways directions of the blocks are parallel to the lengthways directions of the fixing holes 203 so that the blocks 322 can pass through the fixing holes 203. After the blocks 322 pass through the fixing holes 203, the buttons 310 are rotated to drive the blocks 322 to rotate, until the lengthways directions of the blocks 322 are no longer parallel to the lengthways directions of the fixing holes 203. As a result, the blocks 322 cannot pass through the fixing holes 203. Ideally, the blocks 322 are perpendicularly to the lengthways directions of the fixing holes 203. The cylindrical body 321 of each fastener 320 is received in the corresponding hole 102 of the panel 10 and the corresponding fixing hole 203 of the main body 20. The block 322 of the fastener 320 resists against the main body 20 and the head 325 of the button 310 resists against the panel 10, to tightly sandwich the main body 20 and the panel 10. Thus, the panel 10 is tightly fixed to the main body 20.

The lengthways direction of each fixing hole 203 is angled relative to its neighboring fixing holes 203 to prevent unwanted movements of the panel 10 with respective to the main body 20 and unintentional disassembly. In disassembly, the buttons 310 are rotated until the lengthways directions of the blocks 322 are aligned with the lengthways directions of the corresponding fixing holes 203. As a result, the blocks 322 can disengage from the fixing holes 203. Thus, the panel 10 can be detached from the main body 20, while the buttons 310 and the fasteners 320 are still fixed to each other.

The embodiments were chosen and described in order to explain the principles of the invention and their practical application so as to enable others skilled in the art to utilize the invention and various embodiments and with various modifications as are suited to the particular use contemplated. Alternative embodiments will become apparent to those skilled in the art to which the present invention pertains without departing from its spirit and scope. Accordingly, the scope of the present invention is defined by the appended claims rather than the foregoing description and the exemplary embodiments described therein.
