This application claims priority of Chinese Patent Application No. 201110215120.X, filed on Jul. 29, 2011, the disclosure of which is incorporated herein by reference.
1. Field of the Invention
The invention relates to a riser card module, and more particularly to a riser card module that is easy to assemble and that can save space and an electronic device having the same.
Other features and advantages of the present invention will become apparent in the following detailed description of the embodiment with reference to the accompanying drawings, of which:
FIG. 1 is an exploded perspective view of an electronic device according to the embodiment of the present invention;
FIG. 2 is a fragmentary assembled perspective view of the embodiment;
The above-mentioned and other technical contents, features, and effects of this invention will be clearly presented from the following detailed description of one embodiment in coordination with the reference drawings.
Referring to FIGS. 1 and 3, an electronic device 100 according to the embodiment of the present invention is adapted for insertion of a plurality of expansion cards 4. Each of the expansion cards 4 includes a circuit board 41 and a fixing bracket 42. The fixing bracket 42 is L-shaped, and includes an elongated body 421 disposed on one end face of the circuit board 41, a positioning plate 422 protruding perpendicularly from one end of the elongated body 421, and an insert part 423 formed on another end of the elongated body 421 that is distal from the positioning plate 422. The positioning plate 422 is formed with a notch 426, and has a first surface 424 and a second surface 425 opposite to the first surface 424. The expansion cards 4 may be PCI, AGP, or GPU interface cards. The elongated body 421 may be formed with a slot (not shown) for exposure of a connection port (not shown) of the expansion card 4. The electronic device 100 may be a server or a personal computer which can be inserted with the expansion cards 4. In this embodiment, the electronic device 100 is a server. The electronic device 100 includes a housing 1, a substrate 2 and a riser card module 3.
With reference to FIGS. 1 and 2, the housing 1 defines a receiving chamber 10 for accommodating the substrate and the riser card module 3, and includes a main body 11 and a cover body 12 for covering the main body 11. The housing 1 further includes a first positioning element 111, a second positioning element 112 and an engaging stud 113 all disposed on the main body 11. The first positioning element 111 is formed with a first guide groove 114. The second positioning element 112 is formed with a second guide groove 115. The engaging stud 113 may be a screw that is fastened fixedly to the housing 11 and having a head.
