1. Field of the Invention
The present invention relates to a mounting apparatus, and particularly to a mounting apparatus for an expansion card.
2. General Background
Typically, an expansion card such as MPEG Audio Layer3 (MP3) card or an additional circuit board are provided in a portable computer for an additional function, and the expansion card or the additional circuit board are connected to a mother board of the portable computer by a wire. However, a plurality of screws is generally provided to mount the expansion card or the additional circuit board in the portable computer, and it will be discommodious and will waste a lot of time to detach and assemble the expansion card or the additional circuit board.
What is desired, therefore, is a mounting apparatus which is able to fix an expansion card in a portable computer conveniently.
In one preferred embodiment, a mounting apparatus for fixing an expansion card in a base, the mounting apparatus includes a receiving portion, a bracket and a latch. The receiving portion is formed from the base for receiving one end of the expansion card therein, and the bracket is formed from the base opposite to the receiving portion. The latch is rotatablely fixed in the bracket. The latch includes a main body, a handle portion and a pedestal extending from two end of the main body respectively, and the other end of the expansion card is engaged between the handle portion and the pedestal.
Other advantages and novel features will become more apparent from the following detailed description of a preferred embodiment when taken in conjunction with the accompanying drawings, in which:
Referring to FIGS. 1 to 3, a mounting apparatus for an expansion card in accordance with the preferred embodiment of the present invention is adapted for fixing an expansion card 20 to a base 10 of a portable computer. The mounting apparatus includes a receiving portion 30, a bracket 40 and a latch 50.
The base 10 includes a sidewall 13, a plurality of keys 15 is formed from the sidewall 13.
The expansion card 20 includes a first end 21 and a second end 22, and an stepped comer 23 is defined in a bottom of the second end 22. A pair of long sides parallel to each other are defined and extends between the first end 21 and the second end 22. A connector 25 is installed in the expansion card 20. The expansion card 20 is electrically connected to a circuit board through the connector 25 and a wire.
The receiving portion 30 is formed from the base adjacent to the sidewall 13. A receiving recess 31 is defined in the receiving portion 30 for receiving the first end 21 of the expansion card 20 therein.
The bracket 40 is formed adjacent to the sidewall 13 and opposite to the receiving portion 30. The bracket 40 includes two spaced panels 41, 42 parallel with the sidewall 13 respectively. Two engaging slots 44 are defined in opposite sides of the panels 41, 42 respectively, and a hole 43 is defined in each of the panels 41, 42.
The latch 50 includes a main body 55. A pedestal 51 extends from one end of the main body 55, and a handle portion 52 extends from the other end of the main body 55. A groove 511 is defined in the pedestal 51 to engage the stepped comer 23 of the second end 22 of the expansion card 20. The main body 55 includes two sides, and each of the sides of the main body 55 forms a protrusion 53 and a wedge-shaped block 54 corresponding to the holes 43 and the engaging slots 44 of the panels 41, 42.
A fixing portion 60 and a stop plate 70 as a fixing element of the mounting apparatus are formed from the base 10 between the receiving portion 30 and the bracket 40 to protect the expansion card 20 from incline. A slot 61 is defined in the middle of the fixing portion 60 for receiving the expansion card 20 and further fixing the expansion card 20.
Referring also to
The first end 21 of the expansion card 20 is hold in the receiving recess 31 of the receiving portion 30, and then the second end 22 of the expansion card 20 is engaged with the groove 511 of the pedestal 51 of the latch 50, with the middle of the expansion card 20 received in the slot 61 of the fixing portion 60. Pushing the handle portion 52 of the latch 50 toward the expansion card 20 until the wedge-shaped blocks 54 engage in the engaging slots 44 of the panels 41, 42, the second end 22 of the expansion card 20 is completely engaged between the pedestal 51 and the handle portion 52, and the expansion card 20 is finally fixed. The expansion card 20 is adjacent to the sidewall 13, and the expansion card 20 can be controlled to carry out some task by pressing the keys 15 at the sidewall 13.
Referring to
It is believed that the present embodiment and its advantages will be understood from the foregoing description, and it will be apparent that various changes may be made thereto without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the example hereinbefore described merely being preferred or exemplary embodiment.
