Description

Technical Field

[0001] The utility model relates to the technical field of electronic equipment, in particular to a PCIE expansion bracket for a 4U rack-type server. Background Art

[0002] Rack-mounted server chassis are generally designed with standard PCIE card installation positions, but the number is limited to only 7. As the motherboard CPU performance becomes higher and higher and the links become more and more abundant, the 7 PCIE card slots on the standard rack-mounted server chassis can no longer meet the usage needs. Taking a 4U rack-mounted server chassis as an example, the full-height PCIE card occupies less than 3U of height space after installation, making the 1U space above the PCIE card completely wasted.

[0003] At present, if the number of PCIE card installation slots is increased, the slot connectors on the motherboard must be increased, which increases the width of the motherboard and turns it into a non-standard form. That is, a customized chassis must be used, and the motherboard must be designed into a non-standard board shape according to the structure of the customized chassis, which has no universality. Both the chassis and the motherboard are non-standard forms, and the universality of non-standard forms is limited. For the existing mature standard chassis or motherboard solutions on the market, it is impossible to expand the PCIE installation slots. Utility Model Content

[0004] The utility model provides a PCIE expansion bracket for a 4U rack-type server to solve the technical problems mentioned in the background technology.

[0005] In order to achieve the above object, the technical solution of the utility model is implemented as follows:

[0006] The utility model provides a PCIE expansion bracket for a 4U rack-mounted server, comprising:

[0007] The bracket body is installed in the vacant area of ​​the external 4U rack-mounted server;

[0008] Several hardware extensions are arranged on the inner wall of the bracket body, including a PCB adapter board and several PCIE slot connectors, signal connectors and power connectors installed on the PCB adapter board; the several PCIE slot connectors and signal connectors are electrically connected to the power connector.

[0009] Furthermore, there are two hardware expansion pieces, which are respectively installed on the left and right inner walls of the bracket body.

[0010] Furthermore, the number of PCIE slot connectors in the hardware expansion piece is 1 to 3, the number of signal connectors in the hardware expansion piece is twice the number of PCIE slot connectors, and the number of power connectors is 1.

[0011] Furthermore, the PCIE extension bracket also includes a bracket left side plate, and the bracket left side plate is fixedly mounted on the left end surface of the bracket body in a posture parallel to the left side surface of the bracket body.

[0012] Furthermore, the PCIE expansion bracket also includes a bracket right side plate, and the bracket right side plate is fixedly installed obliquely on the right end surface of the bracket body in an outwardly opened posture.

[0013] Furthermore, the PCIE expansion bracket also includes a plurality of PCIE baffle support seats, and the plurality of PCIE baffle support seats are divided into two groups and are respectively fixedly mounted on the left and right inner walls of the bracket body.

[0014] Furthermore, the PCIE expansion bracket also includes two PCIE baffle fixing seats, and the two PCIE baffle fixing seats are respectively fixed on the front and rear sides of the middle part of the bracket body.

[0015] Furthermore, the PCIE extension bracket also includes an insulating film, and the insulating film is adhered to the surface of the bracket body.

[0016] Furthermore, the PCIE expansion bracket also includes a plurality of connectors, and a plurality of hardware expansion components are fixedly mounted on the bracket body through the plurality of connectors.

[0017] Furthermore, a plurality of weight-reducing and heat-dissipating holes are provided on the bracket body.

[0018] Beneficial effects of the utility model:

[0019] If more than 7 PCIE cards are to be installed in the existing technical solution, a customized chassis must be used, and the motherboard must be designed into a non-standard board type according to the structure of the customized chassis, which is not universal. However, the utility model can expand the installation of multiple PCIE cards without changing the structure of the standard 4U rack-mounted server chassis and the board type of the standard EATX server motherboard, without re-customizing the chassis and motherboard, and has high universality.

[0036] Reference Figures 1 to 5 , the embodiment of the present application provides a PCIE expansion bracket for a 4U rack-mounted server, comprising:

[0037] The bracket body 1 is installed in a free area of ​​an external 4U rack-mounted server;

[0038] Several hardware extensions are arranged on the inner wall of the bracket body 1, including a PCB adapter board 12 and several PCIE slot connectors 11, a signal connector 13 and a power connector 14 installed on the PCB adapter board 12; the several PCIE slot connectors 11 and the signal connector 13 are electrically connected to the power connector 14.

[0039] The extended installed PCIE card 15 is plugged into the PCIE slot connector 11 to perform signal or data transmission.

[0040] In some embodiments, the physical dimensions of the bracket body 1 are 475 mm*220 mm*86 mm.

[0041] In some embodiments, the signal connector 13 is an MCIO signal connector, which is an interface for signal input and output between the hardware extension and the standard EATX server motherboard, and is connected to a corresponding interface on the standard EATX server motherboard via a high-speed cable. Because the connection with the standard EATX server motherboard is via a cable, the flexible characteristics of the cable make the installation position of the utility model unrestricted, and the vacant area can be selected according to the actual use of the server.

[0042] In some embodiments, the power connector 14 uses an ATX-8P power connector, which is a power input interface of a hardware expansion component.

[0043] Reference Figure 2 In some embodiments, the number of the hardware extension parts is two, and they are respectively installed on the left and right inner walls of the bracket body 1.

[0044] Reference Figure 2 In some embodiments, the number of PCIE slot connectors 11 in the hardware expansion piece is 1 to 3, the number of signal connectors 13 in the hardware expansion piece is twice the number of PCIE slot connectors 11, and the number of power connectors 14 is 1.

[0045] Preferably, the number of the PCIE slot connectors 11 in the hardware expansion piece is 2, and the number of the signal connectors 13 in the hardware expansion piece is 4.

[0046] Reference Figure 2 and Figure 3 In some embodiments, the PCIE expansion bracket further includes a bracket left side plate 2, which is fixedly mounted on the left end surface of the bracket body 1 in a posture parallel to the left side surface of the bracket body 1. The function of the bracket left side plate 2 is to prevent the air volume from diverging outwards, and at the same time connect the bent part of the bracket body 1 to prevent the bent part of the bracket body 1 from deforming.

[0047] Reference Figure 2 and Figure 3 In some embodiments, the PCIE expansion bracket further includes a bracket right side plate 3, which is fixedly mounted obliquely on the right end surface of the bracket body 1 in an outwardly opened posture. The function of the bracket right side plate 3 is to prevent the air volume from diverging outwards, and at the same time connect the bent part of the bracket body 1 to prevent the bent part of the bracket body 1 from deforming.

[0048] Reference Figure 2 and Figure 3In some embodiments, the PCIE expansion bracket further includes a plurality of PCIE baffle support seats 4, which are divided into two groups and respectively fixedly mounted on the left and right inner walls of the bracket body 1. The function of the PCIE baffle support seats 4 is to guide the PCIE card 15 when it is plugged in, and to support the PCIE baffle.

[0049] Reference Figure 2 and Figure 3 In some embodiments, the PCIE expansion bracket further includes two PCIE baffle fixing seats 5, which are respectively fixed on the front and rear sides of the middle of the bracket body 1. The function of the PCIE baffle fixing seat 5 is to fix the PCIE card 15 after it is inserted, so as to prevent the gold finger connection position on the PCIE card 15 from being stressed and affecting the signal quality.

[0050] Reference Figure 3 In some embodiments, the PCIE extension bracket further includes an insulating film 6, which is bonded to the inner wall of the bracket body 1. The function of the insulating film 6 is to prevent the components at the bottom of the bracket body 1 from contacting the bracket body 1 made of metal material after the PCIE card 15 is installed, thereby causing a short circuit in the device.

[0051] Reference Figure 2 and Figure 3 In some embodiments, the PCIE expansion bracket further includes a plurality of connectors 7 , and a plurality of hardware expansion components are fixedly mounted on the bracket body 1 through the plurality of connectors 7 .

[0052] Specifically, the connector 7 is a standard connector such as a rivet, a rivet nut, a stud, etc., which is used to fix the hardware extension on the bracket body 1.

[0053] Reference Figure 3 In some embodiments, a plurality of weight-reducing and heat-dissipating holes are provided on the bracket body 1. The weight-reducing and heat-dissipating holes are used to reduce weight and facilitate ventilation and heat dissipation.

[0054] In some embodiments, the materials of the bracket body 1, the bracket left side plate 2, the bracket right side plate 3, the PCIE baffle support seat 4 and the PCIE baffle fixing seat 5 are all SECC (electrogalvanized steel plate).

[0055] For a standard 4U rack-mounted server, after the PCIE card 15 is installed in the standard position, its status is as follows Figure 6 As shown, from Figure 6 It can be seen from the figure that the space above the PCIE card 15 in the standard position is completely free. The utility model uses this space to expand the installation of the PCIE card 15 and increase the number of PCIE cards 15 that can be installed in the 4U standard rack server.

[0056] After the four PCIE cards 15 installed for expansion are assembled into a 4U standard rack-mounted server, the status is as follows: Figure 7 As shown. Figure 7 It can be obtained that the newly installed 4 PCIE cards 15 are connected to the standard EATX server motherboard through high-speed cables, and the air ducts of the 7 PCIE cards 15 in the original standard position are independent and do not affect each other. After adopting the design of the utility model, the number of PCIE cards 15 that can be installed in the standard 4U rack server increases from 7 to 11.

[0057] The main advantages of this utility model are:

[0058] The expansion installation of PCIE card 15 can be realized by using a standard 4U rack-mounted server chassis and a standard EATX server motherboard. In other words, any mature standard 4U chassis solution and motherboard solution on the market can realize the expansion installation of PCIE card 15.

[0059] Because the PCIE card 15 installed in the utility model is connected to the standard EATX server motherboard through a high-speed cable, there is no restriction on the installation position. In the conventional solution, the PCIE card 15 is directly plugged into the standard EATX server motherboard. If the number of PCIE cards 15 to be installed is increased, a connector must be added to the standard EATX server motherboard, thereby changing the standard layout and size of the motherboard to a non-standard form. Similarly, in order to fix the newly added PCIE card 15, the rear window structure of the chassis must be changed and also becomes a non-standard form.

[0060] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field can easily think of changes or replacements within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. In addition, the technical solutions between the various implementations of the utility model can be combined with each other, but it must be based on the ability of ordinary technicians in the field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope of the utility model. Therefore, the protection scope of the utility model shall be based on the protection scope of the claims.
