[0051] Figure 1 This is a schematic diagram of a circuit board assembly according to the present invention. Please refer to [link / reference]. Figure 1 The circuit board assembly 20 in this embodiment includes a circuit board body 30, a connector slot 40, and an expansion card fixing structure 100. In this embodiment, the circuit board body 30 is, for example, a motherboard, but the type of circuit board body 30 is not limited thereto.

[0052] A connector slot 40 is disposed on the circuit board body 30. In this embodiment, the connector slot 40 is, for example, a PCI-E interface slot, but the type of connector slot 40 is not limited thereto. An expansion card fixing structure 100 is disposed on the circuit board body 30 and located next to the connector slot 40. The expansion card fixing structure 100 is adapted to fix the expansion card 10 ( Figure 4 ) of the coupling 12 ( Figure 4 ).

[0053] Figure 2 yes Figure 1 A schematic diagram of the expansion card fixing structure. Figures 3 to 4 The expansion card connector was Figure 2 The diagram shows the expansion card fixing structure before and after installation. It should be noted that... Figure 2 It is a perspective view of the base 110 to make the operation of the internal components clear.

[0054] Please see Figures 1 to 4 In this embodiment, the expansion card fixing structure 100 includes a base 110, a fixing member 120, and a torsion spring 130. Figure 2 ).like Figure 1 As shown, the seat 110 includes a first sidewall 111, a second sidewall 112, a third sidewall 113 and a fourth sidewall 114 connected in sequence, a receiving groove 115 surrounded by the first sidewall 111, the second sidewall 112, the third sidewall 113 and the fourth sidewall 114, an upper opening 116 communicating with the receiving groove 115 and a side opening 117 communicating with the receiving groove 115 and located on the first sidewall 111.

[0055] like Figure 2 As shown, the fixing member 120 and the torsion spring 130 are located in the receiving groove 115. In this embodiment, the fixing member 120 is rotatably disposed on the seat body 110. In this embodiment, the fixing member 120 includes a pressing part 124, a hook part 125 connected to each other, and a pivot part 127 located between the pressing part 124 and the hook part 125. The fixing member 120 is pivotally connected to the seat body 110 via the pivot part 127. The pivot part 127 of the fixing member 120 is at least disposed on the second side wall 112 of the seat body 110. In this embodiment, the pivot part 127 of the fixing member 120 is disposed on the opposite second side wall 112 and fourth side wall 114 of the seat body 110.

[0056] Furthermore, in this embodiment, the fastener 120 includes a first segment 121, a second segment 122, and a third segment 123 connected in sequence and with a bend, thus making the fastener 120 J-shaped. The pressing portion 124 is located in the first segment 121, the hook portion 125 is located in the third segment 123, and the pivot portion 127 is located in the second segment 122 or between the first segment 121 and the second segment 122. Of course, in other embodiments, the shape of the fastener 120 is not limited to this.

[0057] Additionally, in this embodiment, the hook portion 125 includes a clearance slope 126 facing the pressing portion 124. The clearance slope 126 is used to avoid interference with the engagement member 12 of the expansion card 10.

[0058] A torsion spring 130 is fitted onto the pivot portion 127. The torsion spring 130 includes a first end 132 and a second end 134, with the first end 132 abutting against the seat 110 and the second end 134 abutting against the fixing member 120. Specifically, the second end 134 of the torsion spring 130 abuts against the second segment 122. For example... Figure 2 As shown, the second end 134 of the torsion spring 130 normally pushes against the second section 122 of the fixing member 120, so that the hook part 125 is in the open state.

[0059] like Figures 3 to 4 As shown, when expansion card 10 is inserted into connector slot 40 ( Figure 1 When the expansion card 10 is engaged, the hook part 12 extends into the receiving groove 115 and presses against the pressing part 124, causing the hook part 125 to rotate and rotate to the top of the hook part 12, and is in the engaged state. At this time, the hook part 125 of the fixing member 120 fixes the hook part 12 of the expansion card 10, so that the expansion card 10 does not come out, and the expansion card 10 can be easily and well fixed.

[0060] It is worth mentioning that, Figure 4 In this state, the torsion spring 130 stores spring force. To release the restriction on the expansion card 10, simply move the hook 12 of the expansion card 10 slightly upward to release the push against the pressing part 124. The torsion spring 130 then releases the stored spring force, pushing the fixing member 120 to rotate clockwise, thereby releasing the restriction of the hook part 125 on the expansion card 10. Furthermore, when the torsion spring 130 releases the stored spring force, the pressing part 124 pushes upward against the hook 12 of the expansion card 10, thus ejecting the hook 12 of the expansion card 10. Therefore, the expansion card 10 can be removed from the expansion card fixing structure 100 quite easily.

[0061] In this embodiment, the connector slot 40 and the expansion card fixing structure 100 are two separate pieces located close to each other. Each is fixed to the circuit board body 30 by a locking fastener. Of course, the form of the expansion card fixing structure 100 is not limited to this; other forms of expansion card fixing structures 100 will be described below. It should be noted that only the main differences from the expansion card fixing structure 100 in the previous embodiment will be described below. Identical or similar components are indicated by the same or similar symbols, and identical content will not be repeated.

[0062] Figures 5 to 7 This is a schematic diagram of various expansion card fixing structures according to this utility model. Please refer to it first. Figure 5 , Figure 5 Expansion card fixing structure 100a and Figure 1 The main difference of the expansion card fixing structure 100 is that, Figure 5 In this circuit, the connector slot 40 and the expansion card fixing structure 100a are integrated. Therefore, the expansion card fixing structure 100a can be fixed to the circuit board body 30 through the connector slot 40 without the need for additional fasteners.

[0063] Please see Figure 6 , Figure 6 The expansion card fixing structure 100b and Figure 1 The main difference between the expansion card fixing structure 100 and the other two lies in the different forms of the bases 110 and 110b. Figure 1 In the middle, the base 110 also includes a recessed section 118, through which the first sidewall 111 is connected to the connector slot 40. Figure 6 In the middle, the first sidewall 111 of the base 110b is directly connected to the connector slot 40.

[0064] Please see Figure 7 , Figure 7 The expansion card fixing structure 100c and Figure 6 The main difference between the expansion card fixing structure 100b and the expansion card fixing structure 100b is that, Figure 6 In the middle, the seat 110b has a first sidewall 111, and the first sidewall 111 is connected to the connector slot 40. Figure 7 In the middle, the seat 110c does not have Figure 6 Instead of the first sidewall 111, the second sidewall 112 and the fourth sidewall 114 are connected to the connector slot 40.

[0065] Figures 8 to 9 This is a schematic diagram showing the expansion card's connecting parts being fixed by another expansion card fixing structure of this utility model before and after. Figure 8 The expansion card fixing structure 100c and Figure 1The main difference between the expansion card fixing structure 100 and the expansion cards 10 and 10c lies in the form of the fixing elements 120 and 120c. Figure 8 In the expansion card 10c, the engagement member 12c also includes a shaft 14, and the fixing member 120c has two parts partially separated by a slot 128, and the engagement member 12c of the expansion card 10 can extend into the slot 128 of the fixing member 120c.

[0066] like Figure 8 As shown, when expansion card 10c is inserted into connector slot 40 ( Figure 1 When the expansion card 10c is engaged, the hook 12c of the expansion card 10c extends into the receiving groove 115 and the slot 128 of the fixing member 120c, and presses against the pressing part 124, causing the hook part 125 to rotate. In particular, the hook part 125 rotates to the top of the shaft 14 and is in the engaged state. At this time, the hook part 125 of the fixing member 120c fixes the shaft 14 of the hook 12c of the expansion card 10c, so that the expansion card 10c does not come out, and the expansion card 10c can be easily and well fixed.

[0067] Figures 5 to 8 The expansion card fixing structures 100a~100c also have fixing elements 120, 120c and torsion spring 130, which can provide good fixation for expansion cards 10, 10c.

[0068] In summary, the expansion card fixing structure of this utility model has a fixing member rotatably mounted on the base, and includes a pressing part and a hook part that are linked to each other. The first end of the torsion spring abuts against the base, and the second end of the torsion spring abuts against the fixing member and normally pushes against the fixing member, thus keeping the hook part in an open state. When the expansion card's engaging part presses against the pressing part, it drives the hook part to rotate, thereby fixing the expansion card's engaging part. Therefore, the expansion card fixing structure of this utility model can easily and effectively fix the expansion card.
