Server and its backplane

The present invention relates to a server, and more particularly to a server having a storage device and its backplane.

Referring to FIG. 1, a perspective view of a conventional server 1 is shown. The server 1 includes a casing 10, a motherboard 11, a central processing module 12, a plurality of hard disks 13, and a back plate 14 of the whole block. The motherboard 11 is disposed within the housing 10. The central processing module 12 is disposed on the motherboard 11. The hard disk 13 is disposed on one side of the casing 10, and the entire back plate 14 is fixed in the casing 10 and located between the motherboard 11 and the hard disk 13. The entire backplane 14 can be electrically connected to the motherboard 11 and the hard disk 13. However, regardless of the amount of demand for the hard disk 13, the size of the entire backplane 14 and the tolerance for the hard disk 13 are fixed and cannot be changed. When the size of the entire backing plate 14 and the tolerance for the hard disk 13 are to be changed, there is no other way than to redesign and replace the entire backing plate 14. This results in inflexible component configuration within the server 1. Moreover, the backboard 14 cannot be applied to the server 1 of different specifications.

In view of the above problems, the present invention provides a server and its backplane for docking various numbers of hard disks.

The invention discloses a server, which comprises a motherboard and a central unit. Processing module and a storage device. The central processing module is disposed on the motherboard. The storage device includes a carrying case, a plurality of hard disks housed in the carrying case, and a back plate fixed to one side of the carrying case. The back plate is formed by splicing a plurality of parallel sub-back plates. Each sub-backboard is provided with at least one slot. The slot is for docking with the corresponding hard drive.

The adjacent sub-backplanes are aligned and electrically connected.

The adjacent sub-backplanes are electrically connected to the female connector through the male connector.

The sub-backplane is located between the motherboard and the hard disk, and is perpendicular to the direction in which the hard disks are docked with the corresponding slots and the motherboard.

The adjacent sub-backplanes are mutually engaged.

The sub-backboard includes an adjacent first sub-backboard and a second sub-backplane. The first sub-backplane includes a first assembly side and a first expansion port disposed on the first assembly side. The second sub-backboard includes a second assembly side adjacent to the first assembly side and a second expansion port disposed on the second assembly side. The second expansion port is opposite to the first expansion port, and the second expansion port is mounted on the first expansion port.

The invention also discloses a backboard formed by splicing a plurality of parallel sub-back panels. Each sub-backboard is provided with at least one slot. The slot is connected to the corresponding one of the hard disks, and the adjacent sub-backplanes are aligned and electrically connected.

The adjacent sub-backplanes are electrically connected to the female connector through the male connector.

The adjacent sub-backplanes are mutually engaged.

The sub-backboard includes an adjacent first sub-backboard and a second sub-backplane. The first sub-backplane includes a first assembly side and a first expansion port disposed on the first assembly side, the second sub-backboard includes a second assembly side adjacent to the first assembly side and is disposed at the second One of the assembly side is a second expansion port, the second expansion port is opposite to the first expansion port, and the second expansion port is mounted on the first expansion port.

According to the server and the backplane of the present invention, the backplane is formed by splicing a plurality of sub-backplanes to flexibly adjust the number of hard disks to which the backplane is docked. Therefore, when the user wants to adjust the number of hard disks in the server, the number of the sub-backplanes can also be changed to adjust the tolerance of the backplane to the hard disk. When the user encounters a server with different specifications, the number and arrangement of the sub-backplanes in the backplane can also be adjusted to match various servers.

The above description of the present invention and the following description of the embodiments of the present invention are intended to illustrate and explain the spirit and principles of the invention.

The main body 7411 has a first assembly side 7411a, a second assembly side 7411b adjacent to the first assembly side 7411a, a third assembly side 7411c adjacent to the first assembly side 7411a and adjacent to the second assembly side 7411b, The fourth assembly side 7411d is adjacent to the second assembly side 7411b and adjacent to one of the first assembly side 7411a and the third assembly side 7411c. In the sub-backplane 741, the slot 7412 is disposed on the main body 7411, the first expansion port 7413 is disposed on the first assembly side 7411a and can be, for example, a female connector, and the second expansion port 7414 is disposed on the second assembly side 7411b. For example, the male connector can be disposed on the third assembly side 7411c and can be, for example, a male connector. The fourth expansion connector 7416 is disposed on the fourth assembly side 7411d and can be, for example, a female connector.

The sub-back boards 741 of the same specifications are aligned with each other. The first expansion connection 埠7413 (female) of the central sub-backboard 741 is electrically butted and mutually clamped to the third expansion connection 埠 7415 (male) of the sub-backboard 741 on the right side. The second extension connector 7414 (male) of the central sub-backplane 741 is electrically butted and mutually latched to the fourth extension port 7416 (mother) of the sub-backplane 741 of the upper side. The third expansion connection of the central sub-board 741 is electrically butted and mutually clamped to the first expansion connection 埠 7413 (mother) of the left sub-back plate 741. The fourth expansion connection 埠7416 (female) of the central sub-backboard 741 is electrically butted and mutually clamped to the second expansion connection 埠7414 (male) of the sub-backplane 741 on the lower side. Therefore, when the size of the extended back plate 74 is to be expanded, it is possible to fight each other by a plurality of sub-back boards 741. Then formed.

In summary, the server and the backplane of the present invention are formed by splicing a plurality of sub-backplanes to flexibly adjust the number of hard disks to which the backplane is docked. Therefore, when the user wants to adjust the number of hard disks in the server, the number of the sub-backplanes can also be changed to adjust the tolerance of the backplane to the hard disk. When the user encounters a server with different specifications, the number and arrangement of the sub-backplanes in the backplane can also be adjusted to match various servers.

Although the present invention has been disclosed above in the foregoing embodiments, it is not intended to limit the invention. It is within the scope of the invention to be modified and modified without departing from the spirit and scope of the invention. Please refer to the attached patent application for the scope of protection defined by the present invention.
