[0002] The main function of the retimer card (signal extension card) is to serve as a signal extender for the server. When the signal distance between the server and the GPUBOX is far, multiple retimer cards are required as relay stations to assist in transmitting signals and connecting the GPU in the GPU BOX. The GPU BOX is generally used as a server box alone, and needs to be configured with a server with a retimer card as the "head", that is, the server is the main host and the GPU BOX is a subordinate link. The server calls the computing resources of the GPU in the GPU BOX to achieve higher performance and faster computing speed. In the related art, the structural design of the server bracket used to carry the retimer card is unreasonable, which makes it inconvenient to integrate the server bracket with other components of the server, and the space utilization rate is low.

DETAILED DESCRIPTION

[0044] 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.

[0045] 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.

[0046] like Figures 1 to 5 As shown, the module bracket of the embodiment of the present invention is provided with a first installation cavity 110 for installing a signal extension card 200 and a second installation cavity 120 for installing a signal extension adapter card 300, the first installation cavity 110 and the second installation cavity 120 are arranged along the 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 signal extension card 200, the plurality of first storage areas 1101 are arranged along the second direction, 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, and the first direction, the second direction and the third direction are orthogonal to each other.

[0047] It should be noted that the signal extension card 200 is also called a retimer card. The signal extension card 200 (retimer card) has the functions of signal extension and signal enhancement.

[0048] 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.

[0049] According to the module bracket 100 of an embodiment of the present invention, since the first installation cavity 110 includes multiple first storage areas 1101, each first storage area 1101 corresponds to at least one signal extension card 200, so that the module bracket 100 can be arranged with multiple signal extension 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, 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, so that the signal extension adapter card 300 can be horizontally arranged in the second installation cavity 120, and at this time, the thickness direction of the signal extension adapter card 300 can be parallel to the third direction.

[0050] Thus, the signal extension adapter card 300 can fully utilize one side of the module bracket 100 along the first direction (such as Figure 1 The module bracket 100 is used to occupy the space at the rear side of the module bracket 100, reduce the size of the module bracket 100 in the third direction, and adapt to the corresponding server chassis 700, reduce the space occupied, and make the structure more compact. On the other hand, the module bracket 100 of the embodiment of the present invention can arrange the signal extension adapter card 300 horizontally. Compared with the solution of "placing the signal extension adapter card 300 vertically and the signal extension adapter stopper at the rear side of the signal extension card 200", it can facilitate the airflow near the signal extension card 200 to flow along the first direction, improve the heat dissipation effect of the signal extension card 200, and extend the service life of the signal extension card 200.

[0051] Optionally, a third installation cavity 130 for installing a hard disk 400 is provided in the module bracket 100, and 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 signal extension 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 1As shown, the hard disk 400 is arranged in the area just above the signal extension card 200. Thus, the hard disk 400 can be installed on one side of the third direction (Z direction) of the signal extension card 200. Compared with the solution in which the signal extension card 200 and the hard disk 400 are spliced ​​through their own brackets, the structure of the module bracket 100 can be compactly arranged, and the space occupied by the server chassis 700 is small, which is conducive to improving space utilization and has low cost.

[0052] According to the module bracket 100 of the embodiment of the present invention, since the first installation cavity 110 includes multiple first storage areas 1101, each first storage area 1101 corresponds to at least one signal extension card 200, so that the module bracket 100 can be arranged with multiple signal extension cards 200 along the second direction, and 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 signal extension card 200 and the hard disk 400 can be arranged along the third direction, and the signal extension adapter card 300 and the signal extension card 200 can be arranged along the first direction, thereby making the structural arrangement of the module bracket 100 compact, occupying less space on the server, which is beneficial to improving space utilization.

[0053] like Figure 3 and Figure 4 As shown, in the projection plane orthogonal to the third direction (z-axis), the outer periphery of the first installation cavity 110 does not overlap with the outer periphery 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 in the projection plane orthogonal to the z-axis direction.

[0054] Therefore, there will be no interference problem between the hard disk 400 and the signal extension adapter card 300 during assembly, and the module bracket 100 of the above solution can improve the heat dissipation problem of the hard disk 400 and the signal extension adapter card 300 by optimizing the arrangement of the first installation cavity 110 and the third installation cavity 130. In other words, the hard disk 400 and the signal extension 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 conducive to improving the heat dissipation efficiency of the hard disk 400 and the signal extension adapter card 300.

[0055] 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. Figure 1As 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 signal extension card 200 can be horizontally installed in 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 signal extension adapter card 300 can be horizontally installed in the second storage area 1201.

[0056] like Figure 1 and Figure 3 As shown, the signal extension adapter card 300 is horizontally arranged in the second installation cavity 120, so that the signal extension adapter card 300 and the signal extension card 200 are plugged in the first direction (X direction), and the horizontally arranged signal extension adapter card 300 can be easily plugged into the signal transmission line, making the installation structure of the signal extension adapter card 300 more compact. Figure 3 As shown, the Z-dimension of the second installation cavity 120 is smaller than the Y-dimension of the second installation cavity 120 , so that the signal extension card 200 can be horizontally placed in the second installation cavity 120 and the overall height of the module bracket 100 is reduced.

[0057] Alternatively, if Figures 2 to 4 As shown, the first storage area 1101 includes at least two first storage positions 11011, and the second installation cavity 120 is provided with at least two second storage areas 1201. The two first storage positions 11011 and the two second storage areas 1201 are arranged along the third direction, and the two first storage positions 11011 and the two second storage areas 1201 are connected one by one. In other words, the two first storage positions 11011 and the two second storage areas 1201 are arranged along the third direction (Z direction), and the first storage position 11011 located in the upper layer and the second storage area 1201 in the upper layer are substantially located at the same horizontal height, and are connected to each other along the first direction (X direction); similarly, the first storage position 11011 located in the lower layer and the second storage area 1201 in the lower layer are substantially located at the same horizontal height, and are connected to each other along the first direction (X direction). This facilitates the plugging of the signal extension card 200 in the first storage position 11011 and the signal extension adapter card 300 in the second storage area 1201.

[0058] like Figure 1 and Figure 2 As shown, since each first storage area 1101 includes at least two first storage positions 11011, that is, each first storage area 1101 can be arranged with two signal extension cards 200 in the Z direction, and the two signal extension cards 200 are arranged horizontally, the module bracket 100 can accommodate more signal extension cards 200 in a limited space, thereby improving the structural compactness of the module bracket 100.

[0059] In addition, since the second storage area 1201 arranged in the Z direction in the second installation cavity 120 can be used to place different signal extension adapter cards 300, the upper and lower layers of signal extension cards 200 can be plugged into the upper and lower layers of signal extension adapter cards 300 accordingly, thereby fully utilizing the space behind the first installation cavity 110, making the structure of the module bracket 100 more compact and the space utilization rate higher.

[0060] In the example of the present invention, Figure 3 and Figure 4 As shown, there are four first storage areas 1101, and the four first storage areas 1101 are arranged in sequence along the second direction (Y direction), and 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 signal extension cards 200, of which four signal extension cards 200 are arranged adjacent to the upper area of ​​the first installation cavity 110, and the other four signal extension cards 200 are arranged adjacent to the lower area of ​​the first installation cavity 110. Correspondingly, there are two signal extension adapter cards 300, and the two signal extension adapter cards 300 are respectively installed in the two second storage areas 1201, and the four signal extension cards 200 on the upper layer are plugged into the signal extension adapter cards 300 on the upper layer, and the four signal extension cards 200 on the lower layer are plugged into the signal extension adapter cards 300 on the lower layer. In this way, the use requirements of the server can be met to a greater extent.

[0061] like Figures 3 to 5 As 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 in the first installation cavity 110 at intervals along the second direction to divide a plurality of first storage areas 1101, and the first baffle 101 is provided with a first slide 1011 protruding toward the direction of the first storage area 1101, the first slide 1011 extends along the first direction, and two first storage positions 11011 are respectively arranged on both sides of the first slide 1011 along the third direction.

[0062] It is understandable that if Figure 3 and Figure 4As shown, a 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 baffles 101 are 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 slide 1011 extends along the first direction and protrudes toward the direction of the first storage area 1101, the first slide 1011 can guide the disassembly and assembly of the upper signal extension card 200 and the lower signal extension card 200. On the other hand, the first slide 1011 can also separate the two layers of signal extension cards 200 in the Z direction by a certain distance in the third direction (Z direction), thereby reserving a certain space for the heat dissipation of the signal extension card 200, thereby improving the heat dissipation effect of the signal extension card 200.

[0063] like Figure 3 , Figure 4 and Figure 6 As shown, the module bracket 100 includes a bracket body 104 and a second baffle 102, and 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 arranged in the second installation cavity 120, and the 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 signal extension adapter cards 300, and the two signal extension adapter cards 300 are horizontally arranged on both sides of the second baffle 102 along the third direction (Z direction), and the signal extension adapter card 300 located at the lower layer is connected to the bracket body 104, and the signal extension adapter card 300 located at the upper layer is connected to the second baffle 102. In this way, the structural strength of the module bracket 100 can be ensured, and the stability of the connection between the module bracket 100 and the signal extension adapter card 300 can be improved.

[0064] In one example, if Figure 6 As shown, the second baffle 102 includes a first beam 1021 and a second beam 1022 , which are stacked along a third direction (Z direction) and can be connected by riveting to improve the support strength of the second baffle 102 .

[0065] like Figure 1 and Figure 3As shown, the third installation cavity 130 includes a plurality of third storage areas 1301, which are arranged in sequence along the second direction, and each third storage area 1301 includes at least two third storage positions 13011, which are arranged along the third direction, and each third storage position 13011 can hold a 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.

[0066] like Figure 1 and Figure 3 As 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. In other words, 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.

[0067] In the example of the present invention, there are three third storage areas 1301, and the three third storage areas 1301 are arranged in sequence along the second direction (Y direction), and each third storage area 1301 is provided with two third storage positions 13011 in the Z direction. In other words, the module bracket 100 can accommodate a maximum of six hard disks 400, of which three hard disks 400 are arranged adjacent to the upper area of ​​the third installation cavity 130, and the other three hard disks 400 are arranged adjacent to the lower area of ​​the third installation cavity 130. In this way, the module bracket 100 can accommodate more hard disks 400 in a limited space, thereby improving the compactness of the structure of the module bracket 100.

[0068] In an exemplary embodiment, Figure 3 and Figure 8 As 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 in the third installation cavity 130 at intervals along the second direction to divide a plurality of third storage areas 1301, and the third baffle 103 is provided with a second slide 1031 protruding toward the direction of the third storage area 1301, the second slide 1031 extends along the first direction, and two third storage positions 13011 are respectively arranged on both sides of the second slide 1031 along the third direction.

[0069] It is understandable that if Figure 3 and Figure 4As shown, a 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 baffles 103 are 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 slide 1031 extends along the first direction and protrudes toward the direction of the third storage area 1301, the second slide 1031 can guide the disassembly and assembly of the upper hard disk 400 and the lower hard disk 400. On the other hand, the second slide 1031 can also separate the upper and lower hard disks 400 by a certain distance in the third direction (Z direction), thereby reserving a certain space for the heat dissipation of the hard disk 400, thereby improving the heat dissipation effect of the hard disk 400.

[0070] like Figures 1 to 4 As shown, a front window module of another embodiment of the present invention comprises: a module bracket 100, a signal extension card 200 and a signal extension adapter card 300, the module bracket 100 is the module bracket 100 of the present invention, there are multiple signal extension cards 200, multiple signal extension cards 200 are installed in the first installation cavity 110, the length direction of the signal extension card 200 is consistent with the first direction, the width direction of the signal extension card 200 is consistent with the second direction, the thickness of the signal extension card 200 is consistent with the third direction, the signal extension adapter card 300 is installed in the second installation cavity 120, and the signal extension adapter card 300 is electrically connected to the signal extension card 200, the length direction of the signal extension card 200 is consistent with the first direction, the width direction of the signal extension card 200 is consistent with the second direction, and the thickness direction of the signal extension card 200 is consistent with the third direction.

[0071] According to the front window module of the embodiment of the present invention, a plurality of signal extension cards 200 can be arranged in the module bracket 100 along the second direction to improve the signal transmission performance of the server. The signal extension adapter card 300 can be arranged horizontally in the second installation cavity 120, so that the signal extension adapter card 300 can make full use of one side of the module bracket 100 along the first direction (such as Figure 1 The space of the module support 100 (behind 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 front window module of the embodiment of the present invention can arrange the signal extension adapter card 300 horizontally. Compared with the scheme of "placing the signal extension adapter card 300 vertically and the signal extension adapter stopper at the rear side of the signal extension card 200", it can facilitate the airflow near the signal extension card 200 to flow along the first direction, improve the heat dissipation effect of the signal extension card 200, and extend the service life of the signal extension card 200.

[0072] Optionally, a third installation cavity 130 for installing a hard disk 400 is provided in the module bracket 100, and the third installation cavity 130 and the first installation cavity 110 are arranged along a third direction. The front window module also includes a hard disk 400 and a hard disk adapter card 500, and 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 signal extension card 200 and the hard disk 400 can be arranged along the third direction, and the signal extension adapter card 300 and the signal extension card 200 can be arranged along the first direction, thereby making the structure of the front window module compact, occupying less space in the server, and being conducive to improving the space utilization of the server.

[0073] Alternatively, if Figure 1 Fig. 9 As shown, the signal extension adapter card 300 includes a card body 301 , a plug-in connector 302 and a high-speed signal connector 303 . The plug-in connector 302 is disposed on the lower side of the card body 301 and plugged with the signal extension card 200 . The high-speed signal connector 303 is disposed on the upper side of the card body 301 .

[0074] Compared with the solution of "the plug-in connector 302 and the high-speed signal connector 303 are arranged on the same side of the third direction (Z direction) of the card body 301", the space occupied by the signal extension adapter card 300 in the height direction can be reduced, so that the thickness of the two signal extension adapter cards 300 after assembly is thinner. Since the high-speed signal connector 303 is arranged on the upper side of the card body 301, the signal extension adapter card 300 can be connected to the high-speed signal transmission cable, and it is easy to plug and unplug.

[0075] 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 along the third direction (Z direction), thereby reducing the probability of the signal extension adapter card 300 being damaged due to the card body 301 of the lower layer of the signal extension adapter card 300 being close to the bottom of the bracket body 104.

[0076] Alternatively, if Figure 1 and Fig. 9 As shown, the signal extension adapter card 300 includes a card body 301, a low-speed signal connector 304 and a power supply connector 305, and the low-speed signal connector 304 and the power supply connector 305 are arranged on the same side of the card body 301 along the second direction (Y direction) of the card body 301. This facilitates the arrangement of electrical circuits.

[0077] Furthermore, if Figure 2As shown, a single wire outlet hole 1042 is provided on one side of the second direction (Y direction) of the bracket body 104, and the single wire outlet hole 1042 respectively leads out two connecting cables of the low-speed signal connector 304 and the power supply connector 305, so as to facilitate the cable planning of the front window module, improve electrical safety, and facilitate wiring.

[0078] like Figure 3 and Figure 4 As shown, before installing the signal extension card 200, it is necessary to install the upper and lower double-layer signal extension adapter cards 300. When installing the lower layer signal extension adapter card 300, it is only necessary to match the first screw hole 306 on the signal extension 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 signal extension adapter card 300, it is only necessary to match the first screw hole 306 on the signal extension adapter card 300 with the second threaded column 1023 on the second baffle 102 one by one, and fasten them with screws.

[0079] 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.

[0080] 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.

[0081] like Figure 4 and Fig.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.

[0082] like Figure 4and Fig.10 As 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 one to one with the multiple third installation cavities 130. In this way, 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 of the Y direction (i.e., the hard disks 400 in different third installation cavities 130) correspond to different hard disk adapter cards 500 respectively. When one of the hard disk adapter cards 500 is damaged, it will not affect the normal operation of the hard disks in other third installation cavities 130.

[0083] like Fig.10 As shown, the hard disk adapter card 500 is provided with a heat dissipation hole 501, which is connected to the third installation cavity 130, and the module bracket 100 is provided with a fixed hook 1032, which is engaged with the heat dissipation hole 501. It can be understood that the heat dissipation hole 501 on the hard disk adapter card 500 can not only be used to ventilate and dissipate heat for the third installation cavity 130, but also can be used to connect with the fixed hook 1032, thereby making the hard disk adapter card 500 simple in structure design and improving the heat dissipation effect of the hard disk 400 and the hard disk adapter card 500.

[0084] Alternatively, if Figure 3 and Fig.10 As shown, the hard disk adapter card 500 is provided with a first positioning portion 502, the module bracket 100 is provided with a first matching portion 1041, the first positioning portion 502 and the first matching portion 1041 are in contact with each other, and the front window module further includes a first threaded member 503, and the first threaded member 503 is passed through the hard disk adapter card 500 and the module bracket 100. In this way, the stability of the hard disk adapter card 500 after installation can be improved, and the positioning is accurate and the installation is convenient.

[0085] For example, Fig.10 As shown, the first positioning portion 502 includes a stop convex hump 5021 and a stop groove 5022, and the first matching portion 1041 is a contoured structure of the first positioning portion 502, so that the first positioning portion 502 and the first matching portion 1041 are installed in alignment, thereby improving the positioning accuracy of the hard disk adapter card 500.

[0086] The first matching portion 1041 is disposed on the bracket body 104. Figure 8 As shown, the fixed hook 1032 is provided on the third baffle 103, and the first matching 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 first hole 1033 on the hard disk adapter card 500 and the third baffle 103 along the first direction (X direction) to improve the stability of the hard disk adapter card 500 after installation.

[0087] like Figure 8 As shown, a contact portion 1034 is provided on the front wall surface of the third baffle 103 , and the hard disk 400 can cooperate with the contact portion 1034 to fix the installation of the hard disk 400 .

[0088] like Figure 1 , Figure 2 and Fig.11 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 in the first installation cavity 110 at intervals along the Y direction, for example, the first baffles 101 are riveted to the bracket body 104. The front window module also includes a signal extension bracket 600, the signal extension card 200 is installed on the signal extension bracket 600, the signal extension bracket 600 can slide into the first storage area 1101 from the front to the back direction, and the signal extension bracket 600 is snap-fitted with the first baffle 101. It can be understood that before assembling the signal extension card 200 to the front window module, the signal extension 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-fitted with the first baffle 101, the stability of the signal extension bracket 600 after assembly can be improved, and it is convenient to disassemble and assemble.

[0089] like Figure 6 and Fig.11 As shown, the first baffle 101 is provided with a first stop groove 1012, the signal extension bracket 600 includes a support frame 601 and a stop plate 602, the signal extension card 200 is installed on the support frame 601, the stop plate 602 is provided at the front side of the support frame 601, and can rotate relative to the support frame 601 in the open position and the closed position, and the stop plate 602 has a hook body 6021, in the open position, the hook body 6021 is separated from the first stop groove 1012, and 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 signal extension card 200 and the module bracket 100, and is easy to disassemble and assemble, and has stronger operability and maintainability.

[0090] It is understandable that when the stop plate 602 is in the closed position, the hook body 6021 protrudes along one side of the second direction (Y direction) to the signal extension bracket 600. Therefore, before the signal extension bracket 600 is inserted into the first storage area 1101, the stop plate 602 needs to be rotated to the open position to avoid interference of the hook body 6021 during the insertion of the signal extension bracket 600.

[0091] like Figure 5 and Fig.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 position limit of the signal extension bracket 600. Then the stop plate 602 can be fixed to the module bracket 100 through the second screw member 603. At this time, the plug-in position 202 of the signal extension card 200 is plugged and matched with the plug-in connector 302 of the signal extension adapter card 300, and the extended connector 201 of the signal extension card 200 extends forward to the signal extension bracket 600.

[0092] A specific embodiment of the front window module of the present invention is described below.

[0093] like Figures 1 to 4 As shown, the front window module includes a module bracket 100, eight signal extension cards 200, two signal extension 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 arranged on the upper side of the first installation cavity 110, and the second installation cavity 120 is arranged on the rear side of the first installation cavity 110.

[0094] The three first baffles 101 in the module support 100 are arranged at equal intervals along the second direction (Y direction) to divide the first installation cavity 110 into four equal first storage areas 1101. A second baffle 102 in the module support 100 is horizontally arranged in the second installation cavity 120 to divide the second installation cavity 120 into two second storage areas 1201 that are equal in upper and lower directions. The two third baffles 103 in the module support 100 are arranged at equal intervals along the second direction (Y direction) to divide the third installation cavity 130 into three equal third storage areas 1301.

[0095] like Figures 1 to 4 As shown, the four signal extension cards 200 of the upper layer are arranged along the second direction (Y direction) and correspond one-to-one with the four first storage areas 1101, and the signal extension cards 200 of the upper layer are arranged adjacent to the upper area of ​​the first storage area 1101. The four signal extension cards 200 of the lower layer are arranged along the second direction (Y direction) and correspond one-to-one with the four first storage areas 1101, and the signal extension cards 200 of the lower layer are arranged adjacent to the lower area of ​​the first storage area 1101. Two signal extension adapter cards 300 are respectively installed in the two second storage areas 1201 of the second installation cavity 120, and the four signal extension cards 200 of the upper layer are plugged into the signal extension adapter cards 300 of the upper layer, and the four signal extension cards 200 of the lower layer are plugged into the signal extension adapter cards 300 of the lower layer.

[0096] like 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.

[0097] 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 .

[0098] According to the server of the embodiment of the present invention, a plurality of signal extension cards 200 may be arranged in the module bracket 100 along the second direction to improve the signal transmission performance of the server. The signal extension adapter card 300 may be arranged horizontally in the second installation cavity 120, so that the signal extension adapter card 300 can make full use of one side of the module bracket 100 along the first direction (such as Figure 1 The space of the module support 100 (behind 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 signal extension adapter card 300 horizontally, which is beneficial for the airflow near the signal extension card 200 to flow along the first direction, improve the heat dissipation effect of the signal extension card 200, and extend the service life of the signal extension card 200, compared with the solution of "the signal extension adapter card 300 is placed vertically, and the signal extension adapter stopper is at the rear side of the signal extension card 200".

[0099] 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.

[0100] like Figure 1 , Fig.12 and Fig.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.

[0101] Since the weight of the entire front window module is relatively large, the weight of the external cable connected to the signal extension card 200 is also relatively large. Furthermore, 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 fixation, thereby improving the stability of the connection between the front window module and the chassis 700.
