[0049] Please see Figures 1 to 5 In this embodiment, the circuit board module 20 is adapted for connection of the expansion card 10. The circuit board module 20 includes a circuit board 30 and an expansion card fixing device 100. The circuit board 30 includes a slot 32 configured for insertion of the insertion portion 12 of the expansion card 10. In this embodiment, the circuit board 30 is, for example, a motherboard, the slot 32 is, for example, a PCI-E slot 32, and the expansion card 10 is, for example, a PCI-E graphics card; however, the types of the circuit board 30, slot 32, and expansion card 10 are not limited thereto.

[0050] The expansion card holder 100 is disposed on the circuit board 30 and located next to the slot 32. The expansion card holder 100 is configured to secure the hook portion 14 of the expansion card 10. Specifically, as... Figure 3 As shown, the expansion card fixing device 100 of this embodiment includes a fixing base 110, a sliding locking member 140, and an elastic member 150.

[0051] The sliding engagement member 140 is movably disposed on the fixed base 110. The fixed base 110 includes a base 120 located below the sliding engagement member 140 and a cover 130 covering the sliding engagement member 140. The sliding engagement member 140 is slidably disposed between the base 120 and the cover 130. The base 120 includes a screw hole 125, and the cover 130 includes a through hole 138. Figure 4 The locking fastener 160 passes through the through hole 138 and is fixed to the screw hole 125 to fix the cover 130 to the base 120.

[0052] The base 120 includes a side wall 121 facing the slot 32 and a limiting groove 122 recessed in the side wall 121. Figure 1 As shown, the sliding engagement piece 140 is normally positioned above the limiting groove 122. Figure 2 As shown, when the sliding card 140 is above the hook 14, the hook 14 of the expansion card 10 is located in the limiting groove 122.

[0053] In addition, by Figure 3 As can be seen, in this embodiment, the fixing base 110 may optionally include two guide ribs 123 protruding from the side wall 121 toward the slot 32, and the space between the two guide ribs 123 communicates with the limiting groove 122. The two guide ribs 123 include two inclined ramps 124 facing each other to form an upwardly expanding opening, and the hook portion 14 of the expansion card 10 is adapted to enter the space between the two guide ribs 123 through the expanding opening.

[0054] Therefore, during the process of inserting the expansion card 10 into the slot 32, the hook 14 of the expansion card 10 will enter the space between the two guide ribs 123 from the bulge opening. This design ensures that the hook 14 of the expansion card 10 will not be tilted.

[0055] In addition, such as Figure 4 As shown, the cover 130 of the fixing seat 110 includes a notch 132 recessed on the side and a receiving groove 134 recessed on the lower surface. The sliding engagement member 140 is located at least partially in the receiving groove 134, and the elastic member 150 is also located in the receiving groove 134.

[0056] In this embodiment, the sliding engagement member 140 includes a slider 146 that slides through the receiving groove 134, and the cover 130 includes a limiting block 136 located within the receiving groove 134. The limiting block 136 is located above the slider 146. The sliding engagement member 140 can move linearly relative to the cover 130 through the engagement of the slider 146 and the limiting block 136. In addition, since the cover 130 is fixed to the base 120, and the limiting block 136 is located above the slider 146, it can restrict the upward movement of the sliding engagement member 140 relative to the cover 130, thus preventing it from disengaging from the cover 130.

[0057] Furthermore, the elastic element 150 is disposed between the fixed base 110 and the sliding engagement element 140. Specifically, as... Figure 5 As shown, the sliding engagement member 140 includes a mounting groove 144, an elastic member 150 located in the mounting groove 144, and a first end 152 of the elastic member 150. Figure 3 The second end 154 of the elastic element 150 abuts against the wall of the mounting groove 144. Figure 3 It abuts against the wall of the receiving groove 134.

[0058] like Figure 1As shown, the sliding engagement member 140 includes a slope 142. In this embodiment, the sliding engagement member 140 is pushed by the elastic member 150, causing the slope 142 to be normally exposed in the recess 132. The slope 142 is designed to change the direction of force application. When the hook 14 of the expansion card 10 contacts the slope 142 of the sliding engagement member 140 from top to bottom, the sliding engagement member 140 will not move downward because it is supported by the base 120. The downward force of the hook 14 of the expansion card 10 will be converted by the slope 142 into a force inward toward the cover 130 (to the right in the figure), causing the sliding engagement member 140 to retract into the cover 130.

[0059] Therefore, in this embodiment, during the process of inserting the plug portion 12 of the expansion card 10 into the slot 32, the hook portion 14 of the expansion card 10 pushes against the inclined surface 142 of the sliding card assembly 140, and the sliding card assembly 140 moves inward toward the fixed base 110 (to the right in the figure) and retracts into the receiving groove 134, so that the hook portion 14 of the expansion card 10 passes through the sliding card assembly 140.

[0060] At this time, the elastic element 150 stores elastic force. After the hook 14 passes the sliding engagement member 140, the elastic element 150 releases the stored elastic force, causing the sliding engagement member 140 to move towards the slot 32 (to the left in the figure), and positioning the sliding engagement member 140 above the hook 14 of the expansion card 10, thereby limiting the upward movement of the hook 14 of the expansion card 10. Therefore, the expansion card fixing device 100 can easily and reliably fix the expansion card 10.

[0061] To remove the expansion card 10, the user can first move the left side of the expansion card 10 upwards, tilting the expansion card 10 so that the hook 14 of the expansion card 10 can first move downwards. Then, the expansion card 10 as a whole is moved to the upper left, so that the hook 14 of the expansion card 10 is disengaged from the limiting position of the sliding card assembly 140. Therefore, the expansion card 10 can be easily removed from the expansion card fixing device 100.

[0062] In other words, the user can use only one hand to install or remove the expansion card 10 during insertion or removal from the slot 32, and the hook 14 of the expansion card 10 can be fixed or detached from the expansion card fixing device 100, which is very convenient to use, and the expansion card fixing device 100 has a simple structure.

[0063] Of course, when removing the expansion card 10, the user can also move the sliding card assembly 140 inward toward the fixing base 110 (to the right in the figure) and then move the expansion card 10 upward, which can also easily remove the expansion card 10.

[0064] The expansion card securing device of this invention has a sliding engagement member movably disposed on a mounting base and includes an inclined surface. An elastic element is disposed between the mounting base and the sliding engagement member. During the insertion of the expansion card into the slot, the hook portion of the expansion card pushes against the inclined surface, causing the sliding engagement member to move inward toward the mounting base, and the elastic element accumulates elastic force. After the hook portion passes the sliding engagement member, the elastic element releases the accumulated elastic force, and the sliding engagement member is positioned above the hook portion to limit its upward movement. Therefore, the expansion card securing device of this invention can easily and reliably secure the expansion card.

[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this case, and not to limit them; although this case has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this case.
