Computer mainframe housing for computer

[0002] The present invention relates to a computer mainframe housing, and more particularly to a quick-detachable computer mainframe housing for holding a computer mainframe unit for test.

[0003] Following fast development of computer technology, advanced personal computers have been continuously developed, and intensively used in different fields for data processing, word processing, inventory control, and any of a variety of purposes. Because computer parts are commonly modularized, they can easily be built up to form a personal computer by the users. FIG. 9 shows a computer housing 5 having installed therein a main board 6, a power supply device 61, a hard diskdrive 62, a floppy diskdrive 63 and a CD-ROM player 64. The computer parts are fastened to the computer housing 5 on the inside by screws 67. After installation of the computer parts, power cables 65 and signal lines 66 are respectively inserted through respective openings at the computer housing 5, and electrically connected to the computer parts in the computer housing 5. Because the computer parts are fastened to the computer housing 5 by screws 67, the installation procedure is complicated. When repairing or replacing one computer part, removal of the computer part in question takes much time and labor.

[0004] The present invention provides a computer mainframe housing for test purpose which is detachable. According to one embodiment of the present invention, the computer mainframe housing comprises a rack formed by using four-way connectors to connect vertical frame bars and horizontal frame bars into a rectangular frame structure, a top board, an intermediate board and a bottom board respectively supported on the horizontal frame bar at different elevations for holding computer parts including a computer main board, a power supply device, floppy and hard diskdrives and a CD-ROM player, a plurality of clamping devices respectively symmetrically fastened to the vertical frame bars at different elevations, and four cover panels respectively fastened to the clamping devices and covered on the rack at four sides, the cover panels each having a plurality of coupling members respectively fastened to the clamping devices at the vertical frame bars, and openings for the passing of power cables and signal lines. A sponge pad may be respectively covered on the bottom board and the intermediate board for positive positioning of the computer parts. The intermediate board has an opening for the passing of power cables and/or signal lines. As an alternate form of the present invention, cover panels and clamping devices are eliminated, and a plastic duct cover is directly covered on the rack for protection against dust. The dust cover has openings for the passing of power cables and signal lines.

[0014] Referring to FIGS. from 1 through 7, a computer housing is shown comprised of a rectangular rack 1. The rectangular rack 1 is a hollow frame structure formed of four-way connectors 114, vertical frame bars 11, and horizontal frame bars 12, 13 and 14. A bottom board 32, at least one intermediate board 131 and a top board 141 are respectively mounted on the horizontal frame bars 12, 13 and 14 at different elevations. In the embodiment shown in FIGS. from 1 through 5, there is provided one intermediate board 131. In the embodiment shown in FIG. 7, there are provided three intermediate boards 131 arranged at different elevations between the top board 141 and the bottom board 32. A sponge pad 33 is covered on the top side wall of the bottom board 32 to support a main board 3. Pins 34 of component parts at the main board 3 are extended out of the bottom side wall of the main board 3, and inserted into the sponge pad 33 to secure the main board 3 in place. The intermediate board 131 has an opening 132 for the passing of cables. A power supply unit 2 is mounted on the intermediate board 131. Floppy diskdrives 4 and 43, a hard diskdrive 42 and a CD-ROM player 41 are arranged in a stack and supported on the intermediate board 131 at one side of the power supply unit 2. The power supply unit 2, the floppy diskdrives 4 and 43, the hard diskdrive 42 and the CD-ROM player 41 each have a plurality of anti-skid foot members 44 at the bottom for positive positioning. After mounting, respective power cables 21 and signal lines 31 are respectively connected to the power supply unit 2, the floppy diskdrives 4 and 43, the hard diskdrive 42 and the CD-ROM player 41. A plurality of clamping devices 111 are symmetrically fastened to the vertical frame bars 11 at different elevations to hold four cover panels 113 around the rack 1. The clamping devices 111 each comprise two clamping portions 112 arranged at right angles to hold two adjacent cover panels 113 at right angles. The cover panels 113 are respectively covered on the four vertical sides of the rack 1, each comprising a plurality of coupling members 1131 for fastening to the clamping devices 111 at the vertical frame bars 11. The coupling members 1131 each comprise a coupling rod 1132, which is forced into engagement with the clamping portion 112 at one clamping device 111. Openings 1133 are respectively provided at the cover panels 113 for the passing of the power cables 21 and/or the signal lines 31.

[0015] FIG. 7 shows an alternate form of the present invention. According to this alternate form, two computer mainframe units (each computer mainframe unit comprises a power supply unit, 3½″ and 5¾″ floppy diskdrives, a hard diskdrive and a CD-ROM player) are respectively arranged in the rack 1 at different elevations.

[0016] Referring to FIG. 8, a cloth covering 45 may be covered on the rack 1 for protection against dust. The cloth covering 45 can be made of plastic sheet material, having different openings 451 at predetermined locations for the passing of power cables and/or signal lines.
