Description

Technical Field

[0001] The present invention relates to the technical field of servers, and in particular, to a module bracket, a front window module and a server. Background Art

[0002] The main function of a retimer card (signal extension card) is to act as a signal extender for a server. When the signal distance between the server and the GPU BOX is far, multiple retimer cards are required as relay stations to assist in signal transmission and connect to the GPUs in the GPU BOX. The GPU BOX is generally a separate server box, and a server with a retimer card needs to be configured as the "brain", that is, the server is the main host and the GPU BOX is in a subordinate connection form. The server calls the computing resources of the GPUs in the GPU BOX to achieve higher performance and faster computing speed. In the related art, the structural design of the server bracket for carrying the retimer card is unreasonable, which is not convenient for integrating the server bracket with other components of the server, and the space utilization rate is relatively low. Summary of the Invention

[0004] To this end, an embodiment of the present invention provides a module bracket that can carry multiple retimer cards, with a compact structural design, which is conducive to improving the space utilization rate of the module bracket.

[0057] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0058] Please refer to the following Figures 1 to 13 The module bracket 100, the front window module and the server according to the embodiment of the present invention are described.

[0059] like Figures 1 to 5 As shown, a first installation cavity 110 for installing a retimer card 200 and a second installation cavity 120 for installing a retimer adapter card 300 are provided in the module bracket of the embodiment of the present invention. The first installation cavity 110 and the second installation cavity 120 are arranged along a first direction. The first installation cavity 110 includes a plurality of first storage areas 1101, each first storage area 1101 corresponds to at least one retimer card 200, and the plurality of first storage areas 1101 are arranged along a second direction. An extension length of the second installation cavity 120 along the first direction and an extension length of the second installation cavity 120 along the second direction are both greater than an extension length of the second installation cavity 120 along the third direction, and the first direction, the second direction and the third direction are orthogonal to each other.

[0060] It should be noted that the retimer card 200 is also called a retimer card. The retimer card 200 (retimer card) has the functions of signal extension and signal enhancement.

[0061] like Figure 1 As shown, the first direction is Figure 1 The positive direction of the X axis is the direction from the back to the front of the module support. The second direction is Figure 1 The positive direction of the Y axis is the direction from left to right of the module bracket. Figure 1 In the Z direction, the positive direction of the Z axis is the direction from bottom to top of the module bracket.

[0062] The module bracket 100 according to an embodiment of the present invention. Since the first installation cavity 110 includes a plurality of first storage areas 1101, and each first storage area 1101 corresponds to at least one retimer card 200, the module bracket 100 can be arranged with a plurality of retimer cards 200 along the second direction to improve the signal transmission performance of the server. Since the first installation cavity 110 and the second installation cavity 120 are arranged along the first direction, and the extension length of the second installation cavity 120 along the first direction and the extension length of the second installation cavity 120 along the second direction are both greater than the extension length of the second installation cavity 120 along the third direction, the retimer adapter card 300 can be horizontally arranged in the second installation cavity 120. At this time, the thickness direction of the retimer adapter card 300 can be parallel to the third direction.

[0063] Thus, the retimer adapter card 300 can make full use of the space on one side of the module bracket 100 along the first direction (such as Figure 1 the rear side of the module bracket 100 in the figure), reduce the size of the module bracket 100 in the third direction, and adapt to the corresponding server chassis 700, reducing the space occupation and making the structure more compact. On the other hand, the module bracket 100 according to an embodiment of the present invention can horizontally arrange the retimer adapter card 300. Compared with the solution of "vertically placing the retimer adapter card 300 and having the signal extension adapter stop at the rear side of the retimer card 200", it can facilitate the airflow near the retimer card 200 to flow along the first direction, improve the heat dissipation effect of the retimer card 200, and extend the service life of the retimer card 200.

[0064] Optionally, a third installation cavity 130 for installing the hard disk 400 is provided in the module bracket 100. The third installation cavity 130 and the first installation cavity 110 are arranged along the third direction. It can be understood that the module bracket 100 can integrate the hard disk 400, and the hard disk 400 is arranged on one side of the retimer card 200 in the third direction. Among them, the first installation cavity 110 and the third installation cavity 130 are located on the same side of the module bracket 100 along the first direction, such as Figure 1 shown in the figure, the hard disk 400 is arranged in the area directly above the retimer card 200. Thus, the hard disk 400 can be installed on one side of the retimer card 200 in the third direction (Z direction). Compared with the solution of splicing the retimer card 200 and the hard disk 400 through their respective brackets, it can make the structural arrangement of the module bracket 100 compact, occupy less space in the server chassis 700, be beneficial to improving the space utilization rate, and have a lower cost.

[0065] According to the module bracket 100 of an embodiment of the present invention, since the first installation cavity 110 includes a plurality of first storage areas 1101, and each first storage area 1101 corresponds to at least one retimer card 200, the module bracket 100 can be arranged with a plurality of retimer cards 200 along the second direction. And because the first installation cavity 110 and the third installation cavity 130 are arranged along the third direction, and the first installation cavity 110 and the second installation cavity 120 are arranged along the first direction, it can be made that the retimer card 200 and the hard disk 400 are arranged along the third direction, and the retimer adapter card 300 and the retimer card 200 are arranged along the first direction. Thus, the structural arrangement of the module bracket 100 can be made compact, occupying less space in the server, which is beneficial to improving the space utilization rate.

[0066] As Figure 3 and Figure 4 shown, in the projection plane orthogonal to the third direction (z-axis), the outer peripheral contour of the first installation cavity 110 does not overlap with the outer peripheral contour of the third installation cavity 130. In other words, there is no overlapping area between the first installation cavity 110 and the third installation cavity 130 on the projection plane orthogonal to the z-axis direction.

[0067] Therefore, there will be no interference problem when the hard disk 400 and the retimer adapter card 300 are assembled, and the module bracket 100 of the above solution can improve the heat dissipation problem of the hard disk 400 and the retimer adapter card 300 by optimizing the arrangement of the first installation cavity 110 and the third installation cavity 130. That is to say, the hard disk 400 and the retimer adapter card 300 respectively installed in the first installation cavity 110 and the second installation cavity 120 can not overlap in the z-axis direction, which is beneficial to improving the heat dissipation efficiency of the hard disk 400 and the retimer adapter card 300 respectively.

[0068] Specifically, the extension length of the first storage area 1101 along the first direction and the extension length of the first storage area 1101 along the second direction are both greater than the extension length of the first storage area 1101 along the third direction. The extension length of the second storage area 1201 along the first direction and the extension length of the second storage area 1201 along the second direction are both greater than the extension length of the second storage area 1201 along the third direction. As Figure 1 shown, the Z-direction dimension of the first storage area 1101 is smaller than the Y-direction dimension and the X-direction dimension of the first storage area 1101, so that the retimer card 200 can be horizontally installed into the first storage area 1101. The Z-direction dimension of the second storage area 1201 is smaller than the Y-direction dimension and the X-direction dimension of the second storage area 1201, so that the retimer adapter card 300 can be horizontally installed into the second storage area 1201.

[0069] As Figure 1 and Figure 3As shown, the retimer adapter card 300 is horizontally arranged in the second installation cavity 120 so that the retimer adapter card 300 can be plugged into the retimer card 200 along the first direction (X direction). Moreover, the horizontally arranged retimer adapter card 300 can facilitate the plugging of signal transmission lines, making the installation structure of the retimer adapter card 300 more compact. Accordingly, as Figure 3 shown, the Z-direction dimension of the second installation cavity 120 is smaller than the Y-direction dimension of the second installation cavity 120, so that the retimer card 200 can be horizontally placed into the second installation cavity 120, and the overall height of the module bracket 100 is reduced.

[0070] Optionally, as Figures 2 to 4 shown, the first storage area 1101 includes at least two first storage positions 11011. At least two second storage areas 1201 are provided in the second installation cavity 120. The two first storage positions 11011 and the two second storage areas 1201 are arranged along the third direction. The two first storage positions 11011 and the two second storage areas 1201 are in one-to-one correspondence and communicate with each other. In other words, the two first storage positions 11011 and the two second storage areas 1201 are both arranged along the third direction (Z direction). The first storage position 11011 on the upper layer and the second storage area 1201 on the upper layer are generally at the same horizontal height and communicate with each other along the first direction (X direction). Similarly, the first storage position 11011 on the lower layer and the second storage area 1201 on the lower layer are generally at the same horizontal height and communicate with each other along the first direction (X direction). This facilitates the plugging of the retimer card 200 in the first storage position 11011 and the retimer adapter card 300 in the second storage area 1201.

[0071] As Figure 1 and Figure 2 shown, since each first storage area 1101 includes at least two first storage positions 11011, that is, two retimer cards 200 can be arranged in the Z direction in each first storage area 1101, and the two retimer cards 200 are horizontally arranged. Thus, the module bracket 100 can accommodate more retimer cards 200 in a limited space, improving the structural compactness of the module bracket 100.

[0072] In addition, since the second storage areas 1201 arranged in the Z direction in the second installation cavity 120 can hold different retimer adapter cards 300, so that the retimer cards 200 in the upper and lower layers can be correspondingly plugged into the retimer adapter cards 300 in the upper and lower layers. Thus, the space behind the first installation cavity 110 is fully utilized, making the structure of the module bracket 100 more compact and the space utilization rate higher.

[0073] In the example of the present invention, as Figure 3and Figure 4 As shown in the figure, there are four first storage areas 1101. The four first storage areas 1101 are arranged in sequence along the second direction (Y direction). Each first storage area 1101 is provided with two first storage positions 11011 in the Z direction. That is to say, the module bracket 100 can accommodate up to eight retimer cards 200 at most. Among them, four retimer cards 200 are arranged adjacent to the upper side area of the first installation cavity 110, and the other four retimer cards 200 are arranged adjacent to the lower side area of the first installation cavity 110. Correspondingly, there are two retimer adapter cards 300. The two retimer adapter cards 300 are respectively installed in the two second storage areas 1201. The four retimer cards 200 on the upper layer are plugged into the upper retimer adapter card 300, and the four retimer cards 200 on the lower layer are plugged into the lower retimer adapter card 300. In this way, the usage requirements of the server can be met in a larger range.

[0074] As Figures 3 to 5 shown in the figure, the module bracket 100 includes a bracket body 104 and a plurality of first baffles 101. The plurality of first baffles 101 are connected to the bracket body 104 and are arranged at intervals in the first installation cavity 110 along the second direction to divide out a plurality of first storage areas 1101. The first baffle 101 is provided with a first slideway 1011 protruding towards the first storage area 1101. The first slideway 1011 extends along the first direction, and the two first storage positions 11011 are arranged on both sides of the first slideway 1011 along the third direction.

[0075] It can be understood that, as Figure 3 and Figure 4 shown in the figure, the plurality of first baffles 101 are arranged at intervals along the second direction (Y direction) to divide the first installation cavity 110 into a plurality of first storage areas 1101. Since the first baffle 101 is arranged in the first installation cavity 110, the structural strength of the module bracket 100 can be improved and the stability is higher. Since the first slideway 1011 extends along the first direction and protrudes towards the first storage area 1101, the first slideway 1011 can guide the disassembly and assembly of the upper retimer card 200 and the lower retimer card 200. On the other hand, the first slideway 1011 can also space out a certain distance between the two layers of retimer cards 200 in the third direction (Z direction), so as to reserve a certain space for the heat dissipation of the retimer card 200 and improve the heat dissipation effect of the retimer card 200.

[0076] As Figure 3 、 Figure 4 and Figure 6As shown, the module bracket 100 includes a bracket body 104 and a second baffle 102. The second baffle 102 is connected to the bracket body 104. For example, the second baffle 102 is riveted to the bracket body 104. The second baffle 102 is disposed within the second installation cavity 120. Two second storage areas 1201 are respectively located on both sides of the second baffle 102 along the third direction. It can be understood that there are two retimer adapter cards 300. The two retimer adapter cards 300 are horizontally arranged on both sides of the second baffle 102 along the third direction (Z direction). The retimer adapter card 300 located at the lower layer is connected to the bracket body 104, and the retimer adapter card 300 located at the upper layer is connected to the second baffle 102. This can ensure the structural strength of the module bracket 100 and improve the stability of the connection between the module bracket 100 and the retimer adapter card 300.

[0077] In one example, as Figure 6 shown, the second baffle 102 includes a first cross beam 1021 and a second cross beam 1022. The first cross beam 1021 and the second cross beam 1022 are stacked along the third direction (Z direction). The first cross beam 1021 and the second cross beam 1022 can be connected by riveting to improve the support strength of the second baffle 102.

[0078] As Figure 1 and Figure 3 shown, the third installation cavity 130 includes a plurality of third storage areas 1301. The plurality of third storage areas 1301 are arranged in sequence along the second direction. Each third storage area 1301 includes at least two third storage positions 13011. The two third storage positions 13011 are arranged along the third direction. Each third storage position 13011 can hold one hard disk 400. The extension length of the third storage position 13011 along the first direction and the extension length of the third storage position 13011 along the second direction are both greater than the extension length of the third storage position 13011 along the third direction, so that the hard disk 400 can be horizontally placed in the third storage position 13011. Compared with the solution of "vertically placing the hard disk 400", the overall height dimension of the front window module can be reduced to adapt to the size of the server chassis 700.

[0079] As Figure 1 and Figure 3 shown, the extension length of the third installation cavity 130 along the first direction is equal to the extension length of the first installation cavity 110 along the first direction. The extension length of the third installation cavity 130 along the second direction is equal to the extension length of the first installation cavity 110 along the second direction. That is to say, the first installation cavity 110 and the third installation cavity 130 are aligned along the first direction (X direction) and along the second direction (Y direction), so that the structure of the module bracket 100 is more regular.

[0080] In an example of the present invention, there are three third storage areas 1301. The three third storage areas 1301 are arranged in sequence along the second direction (Y direction). Each third storage area 1301 is provided with two third storage positions 13011 in the Z direction. That is to say, the module bracket 100 can accommodate up to six hard disks 400 at most. Among them, three hard disks 400 are arranged adjacent to the upper side area of the third installation cavity 130, and the other three hard disks 400 are arranged adjacent to the lower side area of the third installation cavity 130. Thus, the module bracket 100 can accommodate more hard disks 400 in a limited space, improving the structural compactness of the module bracket 100.

[0081] In an exemplary embodiment, as Figure 3 and Figure 8 shown, the module bracket 100 includes a bracket body 104 and a plurality of third baffles 103. The plurality of third baffles 103 are connected to the bracket body 104 and are arranged at intervals in the third installation cavity 130 along the second direction to divide the third installation cavity 130 into a plurality of third storage areas 1301. The third baffle 103 is provided with a second slideway 1031 protruding in the direction of the third storage area 1301. The second slideway 1031 extends along the first direction. Two third storage positions 13011 are arranged on both sides of the second slideway 1031 along the third direction.

[0082] It can be understood that, as Figure 3 and Figure 4 shown, the plurality of third baffles 103 are arranged at intervals along the second direction (Y direction) to divide the third installation cavity 130 into a plurality of third storage areas 1301. Since the third baffle 103 is arranged in the third installation cavity 130, the structural strength of the module bracket 100 can be improved, and the stability is higher. Since the second slideway 1031 extends along the first direction and protrudes in the direction of the third storage area 1301, the second slideway 1031 can guide the disassembly and assembly of the upper-layer hard disk 400 and the lower-layer hard disk 400. On the other hand, the second slideway 1031 can also space the upper and lower layers of hard disks 400 at a certain distance in the third direction (Z direction), thereby reserving a certain space for the heat dissipation of the hard disk 400 and improving the heat dissipation effect of the hard disk 400.

[0083] As Figures 1 to 4As shown in the figure, the front window module of another embodiment of the present invention includes: a module bracket 100, a retimer card 200, and a retimer adapter card 300. The module bracket 100 is the module bracket 100 of the present invention. There are multiple retimer cards 200. The multiple retimer cards 200 are installed in the first installation cavity 110. The length direction of the retimer card 200 is consistent with the first direction, the width direction of the retimer card 200 is consistent with the second direction, and the thickness of the retimer card 200 is consistent with the third direction. The retimer adapter card 300 is installed in the second installation cavity 120, and the retimer adapter card 300 is electrically connected to the retimer card 200. The length direction of the retimer card 200 is consistent with the first direction, the width direction of the retimer card 200 is consistent with the second direction, and the thickness direction of the retimer card 200 is consistent with the third direction.

[0084] According to the front window module of the embodiment of the present invention, multiple retimer cards 200 can be arranged in the module bracket 100 along the second direction to improve the signal transmission performance of the server. The retimer adapter card 300 can be horizontally arranged in the second installation cavity 120. Thus, the retimer adapter card 300 can make full use of the space on one side of the module bracket 100 along the first direction (such as Figure 1 the rear side of the module bracket 100 in the figure), reduce the size of the module bracket 100 in the third direction, and adapt to the corresponding server chassis 700 to reduce the space occupation. On the other hand, the front window module of the embodiment of the present invention can horizontally arrange the retimer adapter card 300. Compared with the scheme of "vertically placing the retimer adapter card 300 and having the signal extension transfer stop at the rear side of the retimer card 200", it can facilitate the airflow near the retimer card 200 to flow along the first direction, improve the heat dissipation effect of the retimer card 200, and extend the service life of the retimer card 200.

[0085] Optionally, a third installation cavity 130 for installing a hard disk 400 is provided in the module bracket 100. The third installation cavity 130 and the first installation cavity 110 are arranged along the third direction. The front window module further includes a hard disk 400 and a hard disk adapter card 500. The hard disk 400 is installed in the third installation cavity 130, and the hard disk 400 is electrically connected to the hard disk adapter card 500. Since the first installation cavity 110 and the third installation cavity 130 are arranged along the third direction, and the first installation cavity 110 and the second installation cavity 120 are arranged along the first direction, the retimer card 200 and the hard disk 400 can be arranged along the third direction, and the retimer adapter card 300 and the retimer card 200 can be arranged along the first direction. Thus, the structural arrangement of the front window module can be compact, occupying less space of the server, which is beneficial to improving the space utilization rate of the server.

[0086] Optionally, as Figure 1 Figure 9 shown, the retimer adapter card 300 includes a card body 301, a pluggable connector 302, and a high-speed signal connector 303. The pluggable connector 302 is disposed on the lower side of the card body 301 and is plugged into the retimer card 200, and the high-speed signal connector 303 is disposed on the upper side of the card body 301.

[0087] Compared with the solution where "the pluggable connector 302 and the high-speed signal connector 303 are disposed on the same side of the third direction (Z direction) of the card body 301", the space occupied by the retimer adapter card 300 in the height direction can be reduced, so that the thickness after assembling two retimer adapter cards 300 is thinner. Since the high-speed signal connector 303 is disposed on the upper side of the card body 301, it is convenient for the retimer adapter card 300 to be connected to the high-speed signal transmission cable and for plugging and unplugging.

[0088] In the example of the present invention, the lower end surface of the card body 301 is spaced apart from the upper end surface of the bracket body 104 in the third direction (Z direction). Thereby, the probability that the card body 301 of the lower retimer adapter card 300 is damaged due to being in close contact with the bottom of the bracket body 104 can be reduced.

[0089] Optionally, as Figure 1 and Figure 9 shown, the retimer adapter card 300 includes a card body 301, a low-speed signal connector 304, and a power supply connector 305. The low-speed signal connector 304 and the power supply connector 305 are disposed on the same side of the card body 301 along the second direction (Y direction) of the card body 301. Thereby, it is convenient for the layout of electrical lines.

[0090] Further, as Figure 2 shown, a single wire outlet hole 1042 is provided on one side of the bracket body 104 in the second direction (Y direction). Two connection cables of the low-speed signal connector 304 and the power supply connector 305 are respectively led out from the single wire outlet hole 1042, so as to facilitate the cable planning of the front window module, improve the electrical safety, and be convenient for wiring.

[0091] As Figure 3 and Figure 4As shown, before installing the retimer card 200, it is necessary to install the upper and lower double-layer retimer adapter cards 300. When installing the lower layer retimer adapter card 300, it is only necessary to match the first screw hole 306 on the retimer adapter card 300 with the first threaded column 1043 on the bracket body 104 one by one, and fasten them with screws. When installing the upper layer retimer adapter card 300, it is only necessary to match the first screw hole 306 on the retimer adapter card 300 with the second threaded column 1023 on the second baffle 102 one by one, and fasten them with screws.

[0092] like Figure 6 and Figure 7 As shown, in order to improve the structural strength of the second baffle 102, the second baffle 102 includes a first beam 1021 and a second beam 1022. The first beam 1021 and the second beam 1022 are stacked on each other along a third direction (Z direction). The first beam 1021 and the second beam 1022 can be connected by riveting to improve the supporting strength of the second baffle 102.

[0093] like Figure 3 , Figure 4 and Figure 6 As shown, the second baffle plate 102 is provided with a first I-shaped nail 1024 on both sides of the Y direction, and the corresponding position of the bracket body 104 is provided with a first nail groove 1044. The second baffle plate 102 is installed on the bracket body 104 from top to bottom, and the first I-shaped nail 1024 can slide into the first nail groove 1044, thereby eliminating the need for external fixing parts, thereby improving the convenience of assembling the second baffle plate 102.

[0094] like Figure 4 and Figure 10 As shown, the hard disk adapter card 500 is arranged at the rear side of the third installation cavity 130 and connected to the module bracket 100. The thickness direction of the hard disk adapter card 500 is consistent with the first direction (X direction) of the module bracket 100. In other words, the card surface of the hard disk adapter card 500 is orthogonal to the first direction (X direction) of the module bracket 100. It can be understood that the hard disk adapter card 500 is arranged vertically and the hard disk adapter card 500 is covered at the rear side of the third installation cavity 130, thereby making the arrangement of the components of the front window module more compact and the space utilization rate higher.

[0095] like Figure 4 and Figure 10As shown, there are multiple hard disk adapter cards 500, and the multiple hard disk adapter cards 500 are arranged at intervals along the second direction (Y direction) of the module bracket 100 and correspond to the multiple third installation cavities 130 one by one. Thus, one or more hard disks 400 in each third installation cavity 130 can share one hard disk adapter card 500, and the hard disks 400 on both sides in the Y direction (i.e., the hard disks 400 in different third installation cavities 130) respectively correspond to different hard disk adapter cards 500. When one of the hard disk adapter cards 500 is damaged, it does not affect the normal operation of the hard disks in other third installation cavities 130.

[0096] As Figure 10 shown, the hard disk adapter card 500 is provided with heat dissipation holes 501, the heat dissipation holes 501 communicate with the third installation cavity 130, and the module bracket 100 is provided with fixed hooks 1032, and the fixed hooks 1032 are clamped with the heat dissipation holes 501. It can be understood that the heat dissipation holes 501 on the hard disk adapter card 500 can not only be used for ventilation and heat dissipation of the third installation cavity 130, but also be used for connection with the fixed hooks 1032. Thus, the structural design of the hard disk adapter card 500 can be simple, and the heat dissipation effect of the hard disk 400 and the hard disk adapter card 500 can be improved.

[0097] Optionally, as Figure 3 and Figure 10 shown, the hard disk adapter card 500 is provided with a first positioning portion 502, the module bracket 100 is provided with a first mating portion 1041, the first positioning portion 502 and the first mating portion 1041 are in abutment with each other, and the front window module further includes a first threaded member 503, and the first threaded member 503 passes through the hard disk adapter card 500 and the module bracket 100. Thus, the stability of the hard disk adapter card 500 after installation can be improved, and the positioning is accurate and the installation is convenient.

[0098] For example, as Figure 10 shown, the first positioning portion 502 includes a stop boss 5021 and a stop groove 5022, and the first mating portion 1041 is a profiling structure of the first positioning portion 502, so as to facilitate the alignment installation of the first positioning portion 502 and the first mating portion 1041 and improve the positioning accuracy of the hard disk adapter card 500.

[0099] Among them, the first mating portion 1041 is arranged on the bracket body 104. As Figure 8 shown, the fixed hook 1032 is arranged on the third baffle 103, and the first mating portion 1041 and the fixed hook 1032 are arranged at intervals along the second direction (Y direction). The first threaded member 503 is arranged adjacent to the fixed hook 1032, and the first threaded member 503 passes through the hard disk adapter card 500 and the first hole 1033 on the third baffle 103 along the first direction (X direction) to improve the stability of the hard disk adapter card 500 after installation.

[0100] As Figure 8As shown, a contact portion 1034 is provided on the wall surface of the front side of the third baffle 103. The hard disk 400 can cooperate with the contact portion 1034 to fix the installation of the hard disk 400.

[0101] As Figure 1 , Figure 2 and Figure 11 shown, the module bracket 100 includes a bracket body 104 and a plurality of first baffles 101. The plurality of first baffles 101 are connected to the bracket body 104 and are arranged at intervals along the Y direction in the first installation cavity 110. For example, the first baffle 101 is riveted to the bracket body 104. The front window module further includes a signal extension bracket 600. The retimer card 200 is installed on the signal extension bracket 600. The signal extension bracket 600 can slide into the first storage area 1101 along the front-to-back direction. The signal extension bracket 600 is snap-connected to the first baffle 101. It can be understood that before assembling the retimer card 200 into the front window module, the retimer card 200 needs to be installed on the signal extension bracket 600 first, and then the signal extension bracket 600 is inserted into the first storage area 1101. Since the signal extension bracket 600 is snap-connected to the first baffle 101, the stability of the signal extension bracket 600 after assembly can be improved, and the disassembly and assembly are convenient.

[0102] As Figure 6 and Figure 11 shown, a first stop groove 1012 is provided on the first baffle 101. The signal extension bracket 600 includes a support frame 601 and a stop baffle 602. The retimer card 200 is installed on the support frame 601. The stop baffle 602 is provided on the front side of the support frame 601 and is rotatable relative to the support frame 601 between an open position and a closed position. The stop baffle 602 has a hook body 6021. In the open position, the hook body 6021 is separated from the first stop groove 1012. In the closed position, the hook body 6021 is engaged in the first stop groove 1012. This can facilitate the installation of the signal extension bracket 600 and the retimer card 200 on the module bracket 100, and the disassembly and assembly are convenient, and the operability and maintainability are stronger.

[0103] It can be understood that when the stop baffle 602 is in the closed position, the hook body 6021 protrudes to the signal extension bracket 600 on one side in the second direction (Y direction). Therefore, before the signal extension bracket 600 is inserted into the first storage area 1101, the stop baffle 602 needs to be rotated to the open position to avoid the interference problem of the hook body 6021 during the insertion process of the signal extension bracket 600.

[0104] As Figure 5 and Figure 11As shown, after the signal extension bracket 600 is inserted into the first storage area 1101, the operator can rotate the stop plate 602 to the closed position so that the hook body 6021 is engaged in the first stop groove 1012, thereby completing the positioning of the signal extension bracket 600. Then, the stop plate 602 can be fixed to the module bracket 100 through the second threaded member 603. At this time, the mating position 202 of the retimer card 200 is plugged and mated with the mating connector 302 of the retimer adapter card 300, and the extension connector 201 of the retimer card 200 extends forward to the signal extension bracket 600.

[0105] A specific embodiment of the front window module of the present invention will be described below.

[0106] As Figures 1 to 4 shown, the front window module includes a module bracket 100, eight retimer cards 200, two retimer adapter cards 300, six hard disks 400, and three hard disk adapter cards 500. The module bracket 100 includes a first installation cavity 110, a second installation cavity 120, and a third installation cavity 130. The third installation cavity 130 is provided on the upper side of the first installation cavity 110, and the second installation cavity 120 is provided on the rear side of the first installation cavity 110.

[0107] Three first baffles 101 in the module bracket 100 are arranged at equal intervals in the second direction (Y direction) to divide the first installation cavity 110 into four equal first storage areas 1101. One second baffle 102 in the module bracket 100 is horizontally arranged in the second installation cavity 120 to divide the second installation cavity 120 into two equal upper and lower second storage areas 1201. Two third baffles 103 in the module bracket 100 are arranged at equal intervals in the second direction (Y direction) to divide the third installation cavity 130 into three equal third storage areas 1301.

[0108] As Figures 1 to 4 shown, the four upper retimer cards 200 are arranged in the second direction (Y direction) and correspond one by one to the four first storage areas 1101. The upper retimer cards 200 are arranged adjacent to the upper side area of the first storage area 1101. The four lower retimer cards 200 are arranged in the second direction (Y direction) and correspond one by one to the four first storage areas 1101. The lower retimer cards 200 are arranged adjacent to the lower side area of the first storage area 1101. The two retimer adapter cards 300 are respectively installed in the two second storage areas 1201 of the second installation cavity 120. The four upper retimer cards 200 are plugged with the upper retimer adapter card 300, and the four lower retimer cards 200 are plugged with the lower retimer adapter card 300.

[0109] As Figures 1 to 4As shown, the six hard disks 400 are divided into two layers, each layer has three hard disks 400 and are arranged in sequence in the second direction (Y direction). The three hard disks 400 in each layer correspond to the three third storage areas 1301 one by one, and the three hard disk adapter cards 500 are respectively installed on the rear sides of the three third installation cavities 130, and each hard disk adapter card 500 is correspondingly plugged into two hard disks 400 arranged in the upper and lower directions.

[0110] A server according to another embodiment of the present invention comprises a front window module and a chassis 700 . The front window module is the front window module of the present invention and is installed in the chassis 700 .

[0111] According to the server of the embodiment of the present invention, a plurality of retimer cards 200 may be arranged in the module support 100 along the second direction to improve the signal transmission performance of the server. The retimer adapter card 300 may be arranged horizontally in the second installation cavity 120, so that the retimer adapter card 300 can make full use of one side of the module support 100 along the first direction (such as Figure 1 The space of the module support 100 (the rear side of the module support 100) is reduced, the size of the module support 100 in the third direction is reduced, and the server chassis 700 is adapted accordingly to reduce the space occupied. On the other hand, the server of the embodiment of the present invention can arrange the retimer adapter card 300 horizontally, which is beneficial for the airflow near the retimer card 200 to flow along the first direction, improve the heat dissipation effect of the retimer card 200, and extend the service life of the retimer card 200, compared with the solution of "placing the retimer adapter card 300 vertically and the signal extension adapter stopper at the rear side of the retimer card 200".

[0112] Optionally, the front window module is slidably engaged with the chassis 700 along the first direction (X direction) of the module bracket 100 , thereby facilitating operators to disassemble and assemble the front window module, thereby improving convenience in using the server.

[0113] like Figure 1 , Figure 12 and Figure 13 As shown, when the front window module is installed in the chassis 700, the operator can push the front window module into the chassis 700 from the front to the back. There is a guide pin 701 on the inner side of the chassis 700, which can guide the disassembly and assembly of the front window module. The bottom of the chassis 700 is provided with a second I-shaped nail 702 to cooperate with the second nail groove 1045 at the bottom of the module bracket 100. In addition, a third screw member 1047 is penetrated through the bottom of the chassis 700 and the bottom of the module bracket 100 to further fix the front window module.

[0114] Since the weight of the entire front window module is relatively large, and the weight of the external wiring cable connected to the retimer card 200 is also relatively large. Further, a third nail groove 1046 is provided on the upper side of the module bracket 100. The third nail groove 1046 can cooperate with the third I-shaped nail 703 on the upper side of the chassis 700 to achieve better guiding and fixing, thereby improving the connection stability between the front window module and the chassis 700.
