2. Description of the Related Art
Currently, many enterprises install relatively cheaper mini servers to satisfy network traffic requirements. In order to improve further economic effect, blade servers are developed. A blade server is a thin, modular electronic board, containing at least one microprocessor and memory that is intended for a single, dedicated application and that can be easily inserted into a rack with many similar servers.
A blade server machine case can accommodate several tends of blade servers or more, and blade server is equivalent to a regular server. These blade servers share the same resources such as server machine case, display, keyboard and power supply unit, achieving easy connection to the big scale data center. Further, the server machine case has installed therein an intelligent system that provides internal resource-related information. The intelligent system can discriminate webbed blade server resources, specific tasks, or application software run on the blade servers, allowing flexible application of every blade server in the server machine case. The most attractive advantage of a blade server is its high reliability and extendibility because every blade server has the backup function. The hot plugging of the server machine case that supports blade servers and system component parts provides high applicability. When one blade server failed, another blade server can take the place without interrupting the service. When wishing to increase the handling power, it needs only to insert more blade servers and to arrange these resources at the place where the demand is most strong.
In order to satisfy the demand for next generation communication equipment and the market demand for high traffic data bandwidth, server blades follow the modular design of Compact PCI specifications. The structural design includes the definition of the server machine case, the main board, the back board, the dimensions of the rear I/O extension board, the height limitation, the connector used, the front panel, the hot plugging handle, and etc. According to this new definition, the 8 U long space of the front face panel is sufficient for accommodating four standard PMC slots and four standard LED displays and can support the hot plugging function of the main board when used with a specific handle. However, a PMC module's user must accurate know the transmission way, interconnection between V (I/O) and rear I/O, and the compatibility of the supported bus arbitration to the carrier board. Further, the power demand for the interface of relatively higher speed and the expansion of next generation silicon circuit requires a change of PMC's specification. These drawbacks impart a barrier to the use of PMC module. Further, a blade server defines the hard diskdrive to be a part of digital ground. Further, when a hard diskdrive is installed in a blade server, it is exposed to the outside and not well protected. This arrangement does not provide an environment for quick dissipation of heat from the hard diskdrive. Therefore, the location and mounting arrangement of hard diskdrives in a server are quite important.
Therefore, it is desirable to provide a diskdrive bracket mounting structure that eliminates the aforesaid problems.
The present invention has been accomplished under the circumstances in view. It is the main object of the present invention to provide a diskdrive bracket mounting structure, which provides both the function of classis ground as well as the function of digital ground. It is another object of the present invention to provide a diskdrive bracket mounting structure, which is practical for repeated use. It is still another object of the present invention to provide a diskdrive bracket mounting structure, which is inexpensive to manufacture and easy to install. To achieve these and other objects of the present invention, the diskdrive bracket mounting structure comprises a bracket, which has a mounting through hole, a hexagonal copper column, which is set at the bottom side of the mounting through hole of the bracket and has a screw hole, a master cushion, which is mounted in the mounting through hole of the bracket and sandwiched between the bracket and the hexagonal copper column and has a shank and a through hole; and a screw, which is inserted through the through hole of the master cushion and threaded into the screw hole of the hexagonal copper column to affix the bracket to the hexagonal copper column and has a head stopped above the master cushion; wherein a supplementary cushion is supported on the top side of the bracket opposite to the hexagonal copper column around the shank of the master cushion and sandwiched in between the head of the screw and the bracket. The master cushion and the supplementary cushion are respectively made out of an electrically insulative material. Further, the master cushion and the supplementary cushion prevent direct contact between the bracket and the hexagonal copper column.
Referring to FIGS. 1˜3, a diskdrive bracket mounting structure in accordance with the present invention is shown comprising a bracket 1, a supplementary cushion 2, a master cushion 3, a hexagonal copper column 4, and a screw 5.
The bracket 1 has a mounting through hole 11.
The supplementary cushion 2 is made out of an electrically insulative material, having a through hole 21 corresponding to the mounting through hole 11 of the bracket 1.
The master cushion 3 is s made out of an electrically insulative material, having a shank 31 insertable through the mounting through hole 11 of the bracket 1 and a through hole 32 axially cut through two distal ends of the shank 31.
The hexagonal copper column 4 has a screw hole 41 extending through the two distal ends thereof.
The screw 5 is a P-head screw insertable through the through hole 21 of the supplementary cushion 2 and the through hole 32 of the master cushion 3 into the screw hole 41 of the hexagonal copper column 4.
Referring to
Further, because the supplementary cushion 2 and the master cushion 3 are electrically insulative and set to prevent direct contact between the bracket 1 and the hexagonal copper column 4, the diskdrive bracket mounting structure provides both the function of classis ground as well as the function of digital ground.
As indicated above, the invention provides a diskdrive bracket mounting structure, which has the following features.
1. The screw 5 is vertically downwardly inserted through the through hole 21 of the supplementary cushion 2 and the through hole 32 of the master cushion 3 and then accurately threaded into the screw hole 41 of the hexagonal copper column 4 to affix the bracket 1 to the hexagonal copper column 4. When not in use, the screw 5 can be directly disconnected from the hexagonal copper column 4, and the parts of the diskdrive bracket mounting structure can be received for a repeated use.
2. The master cushion 3 is attached to the bottom side of the bracket 1 to force the shank 31 into the mounting through hole 11 of the bracket 1 and the through hole 21 of the supplementary cushion 2, and then the hexagonal copper column 4 is attached to the bottom side of the master cushion 3, and then the screw 5 is inserted through the through hole 21 of the supplementary cushion 2 and the through hole 32 of the master cushion 3 and threaded into the screw hole 41 of the hexagonal copper column 4. When the screw 5 and the hexagonal copper column 4 are fastened tight, the master cushion 3 is firmly secured in position between the bracket 1 and the hexagonal copper column 4 without breaking.
3. The parts of the diskdrive bracket mounting structure are inexpensive to manufacture and easy to install.
4. The supplementary cushion 2 and the master cushion 3 prevent direct contact between the bracket 1 and the hexagonal copper column 4, therefore the diskdrive bracket mounting structure provides both the function of classis ground as well as the function of digital ground.
A prototype of diskdrive bracket mounting structure has been constructed with the features of FIGS. 1˜5. The diskdrive bracket mounting structure functions smoothly to provide all of the features disclosed earlier.
Although a particular embodiment of the invention has been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the invention. Accordingly, the invention is not to be limited except as by the appended claims.
