Description of the invention (l), the present invention relates to a mounting sleeve for a personal computer case and a tower device which can be dismantled and slid. This mounting kit contains peripheral devices such as CD-ROMs, DVDs, etc. β The sliding engagement of the mounting case with the casing allows the peripheral device to be more tightly integrated. However, the cage 5 should be easily dismantled by installing the cage, thereby making it easier to access the internal components of the casing. . Others As office and home workspaces become more crowded, the size of personal enclosures and towers is designed to make more efficient use of space. This downsized design provides a more compact computer control, but as the size of the case continues to decrease, its interior becomes smaller. Similarly, the ease of assembling or installing different functional components becomes more difficult. It is still important that for any electrical device, access to this main component, such as the motherboard, is not required to disassemble or interfere with the main auxiliary components and connection devices inside the system. An earlier solution was to try to design a reduced-volume chassis, but still continue to provide access to the internal components. One such solution includes a computer designed with a motherboard on a removable board. This allows borrowing There are many inconveniences in moving the motherboard from the personal computer to the motherboard, but it is not limited to the following: moving the motherboard without moving the input / output (1 / 〇) card is difficult. It is difficult; it is difficult and expensive to go to ground and to accommodate electromagnetic wave shielding; a more complicated and expensive installation process, and a combination of high-cost parts. Other solutions' include a removable disk cage or multiple cages inside a computer case. This drive cage requires a mounting bracket, and one or more drives can be removed from the personal computer by loosening a set of screws. Since the bracket and / or the cage need space to slide inside the casing, this method needs to be larger '.

Therefore, it is necessary to provide a smaller computer case to maintain a solution that allows easy access to internal components of. This method also allows the main components to be inexpensive, but rugged 5 ground contact and / or electromagnetic wave shielding. In addition, access to the inside of the enclosure should be fast and easy to achieve minimal (or no) removal or interference with other components and connection cables. The invention described herein includes a removable drive mounting cage that can be slidably removed from the front and reinstalled in a computer case. This device allows small tower computers to be designed according to, for example, ATX specifications. Relatively smaller than conventional devices. The ΑΠ specification machine board has a processor and a memory placed in a position so that it is to be installed 2 and to maintain a close proximity to the channel of Heji Long. It is hardly placed in front of the motherboard, so a larger case size is established. . This design allows the motherboard to be mounted inside the enclosure, while the drive is slidably mounted in front of the motherboard. Although these drives effectively re-entered the path to the processor and memory, this is a hindrance, by unplugging-controlling this mounting sleeve in place of the positioning bolt, and then moving the mounting cage from the front of the PC architecture Slide forward and get easily resolved. This sliding action is to further protect the metal and non-metal contact surfaces. = Front-mounted removable drive installation kit can allow reduced size and more = Easy to assemble 4Assembly process by moving the drive installation structure ] Cards, cables, and power supplies for women ’s channel machines, Yoshiichi; rules such as processors, memory, and quick pick '5th buy 10 15 20 -----——_________ This paper applies, 丨 national standards (CNS) A4 specification (_ _I ^ ^ n line (Please read the precautions on the back before filling out this page), 1 a? 4〇b356 ------------- B7 V. Description of the invention (3) ~ 1 " Note 1 'hidden body. It is nearly impossible to access such an upgradeable computer component slot without a removable drive installation cage in a computer of the present invention size. In addition, such as The important components of the motherboard can be fixedly attached to the case without removing them. This ensures that the components are properly grounded, thus reducing electromagnetic wave signals that can harm the performance of computers and peripherals. Relatedly, the movable part The grounding of the Amber is not necessary. With the specific description and examples of the present invention, and other specific embodiments, other advantages of the present invention can be made clear from the following description in conjunction with the accompanying drawings, which constitute the present invention.

The other 5 1 / 4-inch hard disks can also be installed A silk private device, such as a 3 1 / 2-inch holder (not shown), is installed. This device is fixed inside the mounting cage 18 through the mounting holes 22 and the rails 24. —The second picture is not displayed! Picture of the chassis 1Q. The magnetic drive installation cage is installed with a decorative bevel 30 on the front side, which is typically made of plastic. The magnetic drive installation cage 18 is slidingly installed through a hole 32 in the front area 16 of the casing frame. . The figure further shows the mounting holes 22 and the rails 24 for mounting peripheral devices in the drive mounting cage 18. The inclined surface 30 may include a flexible elastic buckle or a connecting tab, which is convenient for attaching the inclined surface 30 to the disk drive installation cage. Once installed, the inclined surface 30 becomes the decoration of the drawer-shaped disk drive installation sleeve 18 Front surface. The bevel 30 and the disk drive mounting cover 18 also include a fixing member 34 (for example, a groove 'tab, or other) to attach an additional decorative filling panel (not shown) to hide the unused disk drive groove. ).

Description of the invention (5) The upper surface 46 of the portion 14 is formed. In this preferred embodiment, these guides 44 are also formed of sheet metal. A U-shaped nylon insert or sleeve is inserted into the long side of each track 44. These nylon inserts prevent metal-to-metal contact in the slippage portion. Alternatively, the tracks 40 and / or 44 may be formed from nylon or a similar material. The resulting metal-to-non-metal contact provides the following advantages: reduces friction between the mounting rail 40 of the disk drive mounting cage 18 and the guide rail 44 of the housing 12, and prevents metal contact parts from slipping due to The action creates salty scratches; and reduces metal-to-metal oxidation on and between sliding surfaces. Each of the rear portions 50 of the disk drive mounting cage 40 has a buckled portion 52 or a cut-out portion formed on the 10 track material. These buckled portions 52 and a pair of latches extending from the upper latch 56 or The hooks 54 cooperate with each other. A handle 60 is provided at an end of the upper latch 56. The latch is a sliding part. In this preferred embodiment, it is fixed against two screws with brass sleeves, which screws extend through the holes of the latch, and the latch 56 is against a 15 small coil springs or the like (not shown). Pressing on the locked position. By pulling the handle 60 against the spring, the latch 56 is unbiased and moved to the unlocked position. Once the disk drive mounting cage 18 is installed in the casing 12, the upper latch 56 is held in place by a locking screw or other device that holds the upper flash 56 and the mounting cage 18 in place.

Such tabs include inwardly facing bumps 72. When the disk drive mounting cage 18 slides on the casing 12, the bumps 72 interact with or touch the edges of the disk drive mounting cage 18. The upper surface 42 of the disk mounting cage 18 also includes similar tabs 78 having bumps 80 that contact the upper surface 46 of the casing 12. As shown in FIG.
