[0050] This application provides an extension module 100, such as Figure 1 , 2 As shown, it is applied to the server and includes:

[0051] The frame 1 can be formed by four sides, and the frame 1 encloses and forms a structure for accommodating space to realize the expansion of the card slot;

[0052] Circuit board 2 is fixed in the frame 1 and electrically connected to the motherboard on the server. A plurality of card slots 20 are provided on the first surface 2A of the circuit board 2, and a light micro switch 21 is provided on the second surface 2B of the circuit board 2. The second surface 2B is closer to the frame 1 than the first surface 2A. That is, the gap between the second surface 2B and the frame 1 is smaller, while the gap between the first surface 1A and the frame 1 is larger.

[0053] A light guide button 3 is disposed between the circuit board 2 and the frame 1. The light guide button 3 includes a pressing rod 30 and a light-incident column 31. The head 30A of the pressing rod 30 is exposed in the frame 1. The light-incident column 31 extends from the middle of the pressing rod 30 toward the optical micro switch 21, and the light-incident surface 31A of the light-incident column 31 is close to the optical micro switch 21. The fact that the head 30A of the pressing rod 30 is exposed in the frame 1 can be understood as the pressing rod 30 being visible from the outside of the frame 1. For example, the head 30A of the pressing rod 30 can protrude slightly to the outside of the frame 1, or a through hole can be opened in the frame 1, and the head 30A of the pressing rod 30 is slightly lower than the outer edge of the through hole, so that the head 30A of the pressing rod 30 can be seen from the through hole and can be pressed from the outside of the frame 1.

[0054] When the light guide button 3 is pressed, the light input column 31 triggers the light micro switch 21.

[0055] On circuit board 2, the card slot 20 located on the first surface 2A indicates that the card can be inserted from one side of the first surface 2A. The pins of the card slot 20 can be located on the second surface 2B and led out to a connector on the frame 1 via a cable 22. This connector allows the signals and power supply on circuit board 2 to be electrically connected to the server's motherboard. Alternatively, cable 22 can extend from the gap between the second surface 2B and the frame 1, and can be fixed to the side of the frame 1 using a cable bracket. Other components, such as power connectors for auxiliary card power supply, can also be installed on circuit board 2, depending on actual needs.

[0056] After inserting the card 4 into the card slot 20, the expansion module 100 can be pushed into the server chassis, establishing an electrical connection between the expansion module 100 and the motherboard. When the expansion module 100 is running, the optical microswitch 21 receives electrical signals and emits light to indicate the operating status of the expansion module 100. The light-emitting end of the optical microswitch 21 corresponds to the light-receiving surface 31A. After the light is emitted from the light-emitting end, the light-receiving surface 31A receives it and travels along the light-receiving column 31 and the pressing lever 30 to the head 30A of the pressing lever 30, allowing operators to see the operating status of the expansion module 100 from the outside. The card 4 can be a PCIE (Peripheral Component Interconnect Express) card or other functional cards; there are no restrictions on the type.

[0057] When hot-swapping of the expansion module 100 is required, the operator can press the light guide button 3 from the outside of the expansion module 100. The light guide button 3 moves inward into the expansion module 100, and the light-incident surface 31A of the light-incident pillar 31 moves closer to the optical micro-switch 21 and presses the optical micro-switch 21 to trigger it. At this time, the optical micro-switch 21 generates a hot-swapping signal and transmits it to the motherboard. After receiving the hot-swapping signal, the motherboard performs pre-hot-swapping operations on the expansion module 100, such as data saving and task migration. After the pre-hot-swapping operations are completed, the motherboard sends a completion signal to the optical micro-switch 21 to change the working state displayed by the optical micro-switch 21. When the operator observes the change in working state from the outside through the light guide button 3, the expansion module 100 can be removed to perform its hot-swapping.

[0058] In the server's expansion module, a light microswitch is installed in the small space between the circuit board and the frame. The light transmission that triggers notifications and displays the working status during hot-plugging is implemented on the light guide button, thereby reducing the space occupied in the expansion module and improving the space utilization of the expansion module.

[0059] Depending on the implementation method, the light guide button 3 can be manually pressed and pulled out from outside the expansion module 100, or a reset component or other structure can be set in the expansion module 100 to perform elastic reset after manual pressing, without any restrictions.

[0060] Optionally, this extension module 100, such as Figure 1 , 2 As shown, it also includes:

[0061] The button bracket 5 is fixed to the first side 10 of the frame 1 facing the second surface 2B;

[0062] The reset element 6 is disposed between the button bracket 5 and the light guide button 3, and applies a reset force to the light guide button 3 when the light guide button 3 is pressed.

[0063] The reset element 6 can be a spring, leaf spring, etc., and it abuts against the button bracket 5 and the light guide button 3. When the reset element 6 is compressed by the light guide button 3, it provides a reset force to the light guide button 3 through elasticity. After the light guide button 3 is released, the reset force of the reset element 6 drives the light guide button 3 to return to its initial position, that is, the light-incident column 31 of the light guide button 3 disengages from the light micro switch 21.

[0064] Depending on the function, the reset force provided by the reset component 6 can be either a pulling force or a pushing force, which can be set according to actual needs.

[0065] Optionally, the button bracket 5, as... Figure 2 As shown, it includes:

[0066] A fixing plate 50 is fixed to the first side 10. The fixing plate 50 may be arranged parallel to the first side 10 and fixed to the first side 10 by screwing or riveting.

[0067] The support plate 51 extends from the side of the fixed plate 50 away from the second side 11 of the frame 1 toward the circuit board 2. The second side 11 is the side fixed to the first side 10 and the head 30A of the pressing rod 30 is exposed on the second side 11.

[0068] The button bracket 5 is roughly L-shaped based on the structure of the fixed plate 50 and the support plate 51. The reset member 6 can abut against either the support plate 51 or the fixed plate 50. During installation, the button bracket 5 can be installed on the first side 10 first, and then the reset member 6 and the light guide button 3 can be set so that the reset member 6 abuts against the support plate 51 and the light guide button 3 of the button bracket 5 respectively.

[0069] Optional, such as Figure 2 As shown, a guide groove 50A is provided on the fixed plate 50;

[0070] The light guide button 3 also includes:

[0071] A guide strip 32 is formed in the middle of the light guide button 3 and cooperates with the guide groove 50A;

[0072] The reset sleeve 33 is provided, with one end of the reset member 6 housed within it and the other end of the reset member 6 abutting against the support plate 51.

[0073] During installation, the reset element 6 is secured by the reset sleeve 33 to prevent it from slipping out of the light guide button 3. The guide strip 32 is then slid into the guide groove 50A, allowing it to move along the trajectory of the guide groove 50A into the expansion module 100 until the reset element 6 abuts against the support plate 51. A button sleeve can be formed on the second side 11 to secure the light guide button 3 within the expansion module 100.

[0074] Optional, such as Figure 3 As shown, a bottom portion 50B is formed on the fixed plate 50 on the side away from the first edge 10, and the guide groove 50A is formed on the bottom portion 50B.

[0075] By forming a bottom part 50B on the fixed plate 50 that is far from the first side 10, i.e. protruding into the interior of the expansion module 100, and opening a guide groove 50A on the protruding bottom part 50B, a certain space is created between the fixed plate 50 and the first side 10. When the guide bar 32 slides into the guide groove 50A, the middle part of the guide bar 32 can be locked, thereby preventing the guide bar 32 from coming out when sliding in the guide groove 50A.

[0076] Optional, such as Figure 4 As shown, a sliding cavity 50C is formed on the fixed plate 50, and a guide groove 50A is formed at the bottom of the sliding cavity 50C;

[0077] The light guide button 3 also includes:

[0078] A guide strip 32 is formed in the middle of the light guide button 3 and cooperates with the guide groove 50A;

[0079] A sliding rod 34 is formed at the top end of the guide bar 32 and disposed in the sliding cavity 50C. The reset member 6 is disposed between the sliding rod 34 and the inner wall of the sliding cavity 50C.

[0080] A sliding cavity 50C can be formed on the fixed plate 50, a sliding groove 50A is formed at the bottom of the sliding cavity 50C, a guide strip 32 is formed on the light guide button 3, and a sliding rod 34 is formed at the top of the guide strip 32. When the guide strip 32 slides into the sliding groove 50A, the sliding rod 34 is engaged in the sliding cavity 50C and can slide within the sliding cavity 50C. The reset member 6 can be compressed by the sliding rod 34, and when the light guide button 3 is released from pressure, the light guide button 3 is reset by pushing the sliding rod 34.

[0081] Additionally, it should be noted that the support plate 51 is in Figure 3 , 4 The solution shown can also serve as a limit to prevent the light guide button 3 from being pushed in too far and falling off.

[0082] Specifically, the frame 1, as shown Figure 1 , 5 As shown in Figure 6, it includes:

[0083] The first side 10 faces the second surface 2B of the circuit board 2;

[0084] The second side 11 is fixed to the first side 10 and the head 30A of the pressing rod 30 is exposed on the second side 11;

[0085] The third side 12 faces the first surface 2A of the circuit board 2 and is rotatably connected to the second side 11;

[0086] The fourth side 13 is detachably connected to the third side 12.

[0087] The detachable connection can be achieved through the cooperation of hooks and buckles, pins and through holes, locking rods and rolled edges, etc., and there are no restrictions on this.

[0088] When the third side 12 is separated from the fourth side 13, the third side 12 can rotate relative to the second side 11, thereby opening the expansion module 100 to make it easier to insert and remove the card 4 relative to the card slot 20.

[0089] Optional, such as Figure 1 , 5 As shown in Figure 6, a display through hole 14 is formed on the frame 1, and the head 30A of the pressing rod 30 is close to the interior of the frame 1 relative to the display through hole 14.

[0090] Compared to the setting where the push rod 30 protrudes from the frame 1, the push rod 30 is retracted into the expansion module 100, which can avoid accidental activation and improve the reliability of server use.

[0091] Optional, expansion module 100, such as Figure 1 , 5 As shown in Figure 6, it also includes:

[0092] The self-locking wrench 7 is located on the frame 1, on the exposed side of the head 30A of the pressing rod 30, i.e., the first side 10.

[0093] The self-locking wrench 7, through its interaction with the server's enclosure, allows the expansion module 100 to be pushed into the server. Furthermore, the self-locking wrench 7 can be locked onto the first side 10 for more reliable fixation. The self-locking wrench 7 can be locked using a non-removable screw or similar method.

[0094] Correspondingly, this application also provides a server, such as Figure 1 As shown, it includes:

[0095] Box;

[0096] The motherboard is fixed inside the enclosure; and,
