Patent Application
20130205585
1. Technical Field
The present disclosure relates to mounting apparatuses, and more particularly to a mounting apparatus for securing a circuit board to a bottom panel of a computer enclosure.
2. Description of Related Art
Many mounting apparatuses may include a bolt and a nut. The bolt includes a head portion and a shaft. A bottom panel defines a through hole. A circuit board defines a hole. In use, the shaft is extended through the through hole and the hole in the circuit board, and engaged in the nut to secure the circuit board to the bottom panel. The head portion abuts the bottom panel. Thus, the head portion may increase the overall thickness of the bottom panel.
Therefore, there is room for improvement in the art.
Many aspects of the embodiments can be better understood with references 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 embodiments. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.
The disclosure is illustrated by way of example and not by way of limitation in the figures of the accompanying drawings in which like references indicate similar elements. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean at least one.
Referring to
The bottom panel 10 includes a top surface 151 and a bottom surface 153 opposite to the top surface 151. A polygon-shaped concave portion 11 is located in the bottom panel 10. A through hole 13 is defined in the concave portion 11. In one embodiment, the concave portion 11 is hexagon-shaped.
The circuit board 30 defines an installation opening 31. The installation opening 31 includes a narrow portion 311, a guiding portion 312 communicating with the narrow portion 311, and a wide portion 313 communicating with the guiding portion 312. A flange 33 surrounds the edge of the narrow portion 311 and the guiding portion 312. In one embodiment, the flange 33 is U-shaped. Two guiding surfaces 3121 are located on the flange 33. In one embodiment, the two guiding surfaces 3121 are two beveled surfaces.
The first mounting member 50 includes a positioning portion 51, a connecting portion 53 extending from the positioning portion 51, and an installation portion 55 extending from the connecting portion 53. In one embodiment, the installation portion 55 extends from the positioning portion 51. The positioning portion 51 has a polygon-shape corresponding to the concave portion 11. A thickness of the positioning portion 51 is smaller than or equal to depressed depth of the concave portion 11. The positioning portion 51 can be received in the concave portion 11. The connecting portion 53 can be received in the through hole 13. Outer thread 551 is formed on outer surface of the installation portion 55. In one embodiment, the positioning portion 51 is hexagon-shaped, and the installation portion 55 is column-shaped.
The second mounting member 70 includes a stopper portion 71 and a locking portion 73 extending from the stopper portion 71. A plurality of blocking portions 711 is located on the outer surface of the stopper portion 71, for facilitating the rotation of the stopper portion 71. The stopper portion 71 has a first cross section taken along a plane parallel to the bottom panel 10, and the locking portion 73 has a second cross section taken along the plane. Area of the first cross section is greater than area of the second cross section. An installation hole 75 is defined in the locking portion 73 through the stopper portion 71. Inner thread 731 is formed on the inner surface of the installation hole 75, for engaging with the outer thread 551 of the first mounting member 50.
Referring to
The stopper portion 71 is aligned to the wide portion 313 of the installation opening 31. The circuit board 30 is moved towards the bottom panel 10, until the second mounting member 70 extends through the wide part 313, and then the circuit board 30 is moved so that the mounting member 70 is extended through the narrow portion 311 contacts the flange 33 of the circuit board 30. At this time, the locking portion 73 is located in the narrow portion 311 and the stopper portion 71 resists the flange 22.
In disassembly, the circuit board 30 is moved parallel to the bottom panel 10 until the stopper portion 71 disengages from the flange 33 and the second mounting member 70 moves to the wide part 313 from the narrow portion 311. Thereby the circuit board 30 is easily dismounted from the bottom panel 10.
It is to be understood, however, that even though numerous characteristics and advantages have been set forth in the foregoing description of embodiments, 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 the 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.
