Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application is a divisional of U.S. patent application
Ser. No. 13/231,143, filed on Sep. 13, 2011, titled "MOUNTING
APPARATUS FOR CIRCUIT BOARD".
BACKGROUND
[0002] 1. Technical Field
[0003] 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.
[0004] 2. Description of Related Art
[0005] 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.
[0006] Therefore, there is room for improvement in the art.
BRIEF DESCRIPTION OF THE DRAWINGS
[0007] 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.
[0008] FIG. 1 is an exploded, isometric view of an embodiment of a
mounting apparatus for a circuit board.
[0009] FIG. 2 is similar to FIG. 1, but viewed in a different
aspect.
[0010] FIG. 3 is an assembled view of FIG. 1.
[0011] FIG. 4 is an assembled view of FIG. 2.
DETAILED DESCRIPTION
[0012] 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.
[0013] Referring to FIGS. 1-2, a mounting apparatus for securing a
circuit board 30, in accordance with an embodiment, includes a
bottom panel 10, a first mounting member 50, and a second mounting
member 70. In one embodiment, the bottom panel 10 is a bottom panel
of a computer enclosure.
[0014] 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.
[0015] 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.
[0016] 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.
[0017] 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.
[0018] Referring to FIGS. 3-4, in assembly, the first mounting
member 50 is moved toward the bottom panel 10, until the
installation portion 55 is through the through hole 13. The
positioning portion 51 is received in the concave portion 11, for
preventing rotation relative to the bottom panel 10, and the
connecting portion 53 is received in the through hole 13. The
second mounting member 70 is moved towards the installation portion
55, until the installation hole 75 is aligned with the installation
portion 55. The second mounting member 70 is rotated to drive the
installation portion 55 into the installation hole 75, until the
outer thread 551 completely occludes the inner thread 731.
Therefore, the bottom panel 20 is secured to the first mounting
member 50, and the locking portion 73 abuts the top surface 151 of
the bottom panel 10. In this position, the locking portion 73 is
between the bottom panel 10 and the stopper portion 71.
[0019] 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.
[0020] 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.
[0021] 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.
