Description

Technical Field

[0001] The present invention relates to a retaining system for expansion cards, and more particularly to a multi-axis adjustable retaining system for expansion cards, which uses a plurality of retaining members to retain the expansion cards in multiple directions. Background Art

[0002] In increasingly demanding environments and scenarios, the ability of expansion cards to be securely fixed is crucial to the stability of the system. Current technology, which only secures expansion cards in one direction, often only offers a vibration resistance of 0.5G. Furthermore, when unexpected vibrations occur, the expansion card can be pulled out of the slot, causing system signal loss or even serious issues such as system crashes.

[0003] In addition, as the functions of expansion cards expand, the external dimensions of expansion cards are no longer fixed. Therefore, the original fixing method is bound to be no longer universal, and new structures and fixing methods are needed to solve these problems. Summary of the Invention

DETAILED DESCRIPTION

[0023] See also Figure 1 and Figure 2 , which is a schematic diagram and a roughly exploded schematic diagram of the multi-axis adjustable retaining system for expansion cards of the present invention. Figure 1 and Figure 2 As shown, the multi-axis adjustable holding system 1 for expansion cards includes a fixing structure 3 , a first holding member 11 , a second holding member 12 , a third holding member 13 and a fourth holding member 14 .

[0024] First, it is explained that the multi-axis adjustable retaining system 1 for expansion cards of the present invention is suitable for retaining an expansion card 2 including a connector 20. The expansion card 2 is inserted into a slot 41 of a circuit board 4 with the connector 20.

[0025] like Figure 2As shown, the expansion card 2 further includes a bottom 20a on which a connector 20 is disposed, a front end 21 having two ends connected to the bottom 20a and a top 22, respectively, and a first side 23 and a second side 24 connecting the top 22 and opposite sides of the bottom 20a. The connector 20 of the expansion card 2 may be, but is not limited to, a card edge connector (gold finger connector), typically provided with a row of second terminals, and the sidewalls of the slot 41 correspondingly provided with a row of first terminals for coupling to the second terminals. The circuit board 4 is typically a motherboard, but the present invention is not limited thereto. The surface shapes of the first side 23 and the second side 24 of the expansion card 2 include one of a flat or substantially flat surface (e.g., the circuit board surface of the expansion card 2, the flat surface of an electronic component, the flat surface of a motor component (such as a flat surface of a heat sink), etc.), an inclined surface (e.g., the inclined surface of a motor component), and a curved surface (e.g., the curved surface of a motor component).

[0026] like Figure 1 and Figure 3 As shown, it can be defined first that the direction in which the expansion card 2 is inserted into the slot 41 is defined as a first direction D1, the extension direction of the connector 20 (for example, the arrangement direction of the plurality of second terminals, or the length direction of the slot 41) is defined as a second direction D2, and the normal vector of a plane formed by the first direction D1 and the second direction D2 (for example, the width direction of the slot 41) is defined as a third direction D3.

[0027] Specifically, at least a portion of the expansion card 2 is disposed within a mounting space 30 defined by a mounting structure 3. For example, the mounting structure 3 can be any of the following: a chassis 31, a housing 32, or a combination of the chassis 31 and the housing 32. This provides a secure support for the various retaining components in the multi-axis adjustable retaining system 1 for the expansion card, thereby stably retaining the expansion card 2. Generally, the circuit board 4 is also disposed within the mounting structure 3, with the slot 41 located within the mounting space 30. The housing 32 is typically disposed outside the chassis 31 relative to the mounting space 30.

[0028] like Figure 3As shown, the first retaining member 11 includes a first retaining portion 110 and a first adjustment portion 111. The first adjustment portion 111 is configured to adjust its position relative to the fixed structure 3. When the first adjustment portion 111 is located at the fixed structure 3, the first retaining portion 110 holds the front end 21. In a feasible embodiment, the first adjustment portion 111 is configured to adjust its position relative to the fixed structure 3 in a fourth direction D4. The fourth direction D4 is parallel to or at an acute angle to the second direction D2. The fourth direction D4 is adjusted in one of a variety of directions to adjust the first adjustment portion 111, thereby generating a thrust component of the first retaining portion 110 parallel to the second direction D2, thereby pressing the expansion card 2 against the slot 41 in the second direction D2. A turning angle is formed between the extension direction of the first retaining portion 110 and the extension direction of the first adjustment portion 111. Specifically, the fourth direction D4 is parallel to the second direction D2, and the turning angle is a right angle.

[0029] like Figure 3 As shown, in another possible embodiment, the first retaining portion 110 includes a first slot 1100, allowing a locking member 5 to adjust the position of the first retaining portion 110 retaining the front end 21 through the first slot 1100. Specifically, taking the first slot 1100 as a slot having semicircular holes at both ends and a rectangular hole between the two ends communicating with the semicircular holes, the length direction of the first slot 1100 (or rectangular hole) is parallel to or forms an acute angle with the first direction D1. However, the first slot 1100 may also be a rectangular hole, a polygonal hole with a maximum length, or an oblong hole. The locking member 5 is adjusted relative to the front end 21 and / or the bracket provided on the front end 21 along the length direction of the first slot 1100 through the first slot 1100. In other words, the height component of the first slot 1100 parallel to the first direction D1 can be adjusted to accommodate the height of the expansion card 2 (in the first direction D1). Furthermore, the length direction of the first slot 1100 is parallel to the first direction D1.

[0030] Similarly, the first adjustment portion 111 includes a second slot 1110, through which a locking member 5 can be inserted to adjust the position of the first adjustment portion 111 on the fixed structure 3. The shape of the second slot 1110 is similar to that of the first slot 1100. Therefore, the position of the locking member 5 locked to the fixed structure 3 can be adjusted along the length of the second slot 1110. In other words, the length component of the second slot 1110 parallel to the second direction D2, as adjusted in one of the various directions, can be adjusted to accommodate the length of the expansion card 2 (the second direction D2). Specifically, the length of the second slot 1110 is parallel to the second direction D2.

[0031] In a possible embodiment, if Figure 4As shown, the fixing structure 3 further includes a bridge plate 33 having a first opening 330 connecting two opposing surfaces of the bridge plate 33. The top portion 22 is positioned between the first opening 330 and the slot 41, allowing the second retaining unit 120 to press against the top portion 22 through the first opening 330. The bridge plate 33 is mounted on the fixing structure 3, such as a rack 31. In this example, opposing sides of the bridge plate 33 are mounted on two frames of the rack 31 on opposing sides of the expansion card 2, such that the top portion 22 is positioned between the slot 41 and the first opening 330, allowing the second retaining unit 120 to press against the top portion 22 through the first opening 330.

[0032] Furthermore, the second adjustment unit 121 includes a first plate 1211 and a second plate 1212 connected by a first transition 1210, and a third plate 1214 and a fourth plate 1215 connected by a second transition 1213. The first plate 1211 and the third plate 1214 each include a third slot 12110. The two third slots 12110 are located on opposite sides of the first opening 330 and are parallel to each other. These slots allow two locking members 5 to adjust the position of the second adjustment unit 121 locked to the bridge plate 33 through the two third slots 12110. The second plate 1212 and the fourth plate 1215 each include a fourth slot 12111. The two fourth slots 12111 are parallel to each other. These slots allow the other two locking members 5 to adjust the position of the second retaining unit 120 pressing against the top portion 22 through the first opening 330 through the two fourth slots 12111.

[0033] Please refer to Figure 4 Specifically, the shape of the third slot 12110 is similar to that of the first slot 1100. The length direction (eighth direction D8) of the third slot 12110 is parallel to or forms an acute angle with the second direction D2. Thus, the position of the second retaining unit 120 against the top portion 22 can be adjusted by adjusting one of the various length components of the third slot 12110 that are parallel to the second direction D2. Furthermore, the length direction (eighth direction D8) of the third slot 12110 is parallel to the second direction D2.

[0034] For further information, please refer to Figure 4 and Figure 5 , Figure 5 for Figure 4A cross-sectional view along line AA' shows the second retaining unit 120 as a box or U-shaped structure with an opening. Opposite ends of the bottom surface 1201 of the second retaining unit 120 are connected to two side surfaces 1202 of the second retaining unit 120, and each side surface 1202 includes a through-hole 1203. The shape of the fourth slot 12111 is similar to that of the first slot 1100, allowing the locking member 5 to be adjusted along the length of the fourth slot 12111 (fifth direction D5) to secure the locking member 5 within the through-hole 1203. The fifth direction D5 is parallel to or at an acute angle to the first direction D1. Thus, the height component of the fourth slot 12111 parallel to the first direction D1 can be adjusted to accommodate the height of the expansion card 2 (first direction D1). This allows the position of the bottom surface 1201 against the top 22 to be adjusted to accommodate various possible heights of the top 22 (first direction D1) after insertion into the slot 41. Furthermore, the length direction (fifth direction D5 ) of the fourth slot 12111 is parallel to the first direction D1 .

[0035] Optionally, the multi-axis adjustable holding system 1 for expansion cards of the present invention further includes a first buffer unit 6. Figure 5 As shown, the first buffer unit 6 is disposed on the second retaining unit 120, such that the first buffer unit 6 is located between the second retaining unit 120 and the top portion 22. For example, the material of the first buffer unit 6 is any of the following: rubber, foam, resin, plastic, cork, silicone, or a combination of at least two of these (e.g., overlapping sheets of different materials, a woven structure, etc.). Furthermore, the first buffer unit 6 is disposed on the bottom surface 1201 to prevent damage to the top portion 22 when the bottom surface 1201 presses against the top portion 22.

[0036] In a possible embodiment, if Figure 6 and Figure 7 As shown, Figure 7 for Figure 6 A schematic cross-sectional view along line BB'. The bridge plate 33 also includes two fifth slots 331 connecting two opposing surfaces of the bridge plate. The third retaining portion 130 and the fourth retaining portion 140 each pass through a corresponding fifth slot 331, positioning the first side 23 and the second side 24 between the third retaining portion 130 and the fourth retaining portion 140, respectively. This allows for adjustment of the distance between the third retaining portion 130 and the first side 23, and between the fourth retaining portion 140 and the second side 24. The third adjustment portion 131 and the fourth adjustment portion 141 each also include a sixth slot 1310, allowing a locking member 5 to adjust the position of the third retaining portion 130 and the fourth retaining portion 140 securing the first side 23 and the second side 24, respectively, through the two sixth slots 1310. The locking member 5 is secured to the bridge plate 33 through the two sixth slots 1310. Note that the positions of the third retaining member 13 and the fourth retaining member 14 are interchangeable.

[0037] Specifically, the third retaining portion 130 and the third adjustment portion 131 are connected by a transition, and the fourth retaining portion 140 and the fourth adjustment portion 141 are connected by another transition. The third retaining portion 130 and the fourth retaining portion 140 are each adjusted in a sixth direction D6 to correspond to a fifth slot 331, thereby clamping the expansion card 22 between the third retaining portion 130 and the fourth retaining portion 140. The fifth slot 331 is rectangular or similar in shape to the first slot 1100. The sixth direction D6 is parallel to or forms an acute angle with the third direction D3. In this way, the third retaining portion 130 and the fourth retaining portion 140 can adapt to the width (third direction D3) and / or side profile of the expansion card 2 by adjusting the sixth slot 1310 in one of various directions, along a width component parallel to the third direction D3. Specifically, the sixth direction D6 is parallel to the third direction D3.

[0038] like Figure 6 As shown, please refer to Figure 7 The third adjustment portion 131 and the fourth adjustment portion 141 overlap with each other, and the sixth slots 1310 of the two also at least partially overlap. The shape of the sixth slots 1310 is similar to that of the first slots 1100, so that the locking member 5 can be locked to the bridge plate 33 through the two sixth slots 1310 and the through holes or slots of the bridge plate 33.

[0039] Optionally, the multi-axis adjustable retaining system 1 for an expansion card of the present invention further includes at least one second buffer unit 7. The second buffer unit 7 is disposed on one of the third retaining portion 130 and the fourth retaining portion 140, such that the second buffer unit 7 is located between the third retaining portion 130 and the first side surface 23, or between the fourth retaining portion 140 and the second side surface 24.

[0040] For example, the material of the second buffer unit 7 can be any of the following: rubber, foam, resin, plastic, cork, silicone, or a combination of at least two of these (e.g., overlapping sheets of different materials, a woven structure, etc.). Furthermore, the second buffer unit 7 prevents damage to the first side surface 23 or the second side surface 24 when the third retaining portion 130 or the fourth retaining portion 140 clamps the expansion card 2. Ideally, two second buffer units 7 can be disposed on the third retaining portion 130 and the fourth retaining portion 140, respectively.

[0041] Please come back Figure 6The multi-axis adjustable retaining system 1 for an expansion card of the present invention further includes a third adjustment member 15. The third adjustment member 15 includes two parallel seventh slots 150 and at least one second opening 151. The bridge plate 33 further includes an eighth slot 332 connecting two opposing surfaces of the bridge plate. The third retaining portion 130 and the fourth retaining portion 140 respectively pass through the fifth slot 331 via the second opening 151. The lengths of the two seventh slots 150 and the eighth slot 332 are parallel to each other. When the third retaining portion 130 and the fourth retaining portion 140 respectively retain the first side 23 and the second side 24, the two seventh slots 150 allow the other two locking members 5 to adjust the position of the third adjustment member 15 locked to the bridge plate 33. The eighth slot 332 allows the locking member 5 to be locked to the bridge plate 33 in sequence through the two sixth slots 1310, the through-hole or the second opening 151 of the third adjustment member 15, and the eighth slot 332.

[0042] Specifically, the shapes of the seventh slot 150 and the eighth slot 332 are similar to those of the first slot 1100. The length direction (seventh direction D7) of the seventh slot 150, the second opening 151, and the eighth slot 332 is parallel to or forms an acute angle with the second direction D2. Thus, the length component of the seventh slot 150 parallel to the second direction D2 can be adjusted to accommodate the length of the expansion card 2 (second direction D2). Furthermore, the seventh direction D7 is parallel to the second direction D2.

[0043] Ideally, when the third adjusting member 15 is stacked on the bridge board 33, at least one second opening 151 is located above the fifth slot 331, allowing the third retaining portion 130 and the fourth retaining portion 140 to pass through the second opening 151 and the fifth slot 331, respectively. Furthermore, while the second seventh slot 150 allows the other two locking members 5 to adjust the position of the third adjusting member 15 locked to the bridge board 33, the other locking member 5 also moves along the parallel eighth slot 332. When the third retaining portion 130 and the fourth retaining portion 140 clamp the expansion card 22, the other locking member 5 is locked to the bridge board 33 by sequentially passing through the second sixth slot 1310, the through-hole or second opening 151 of the third adjusting member 15, and the eighth slot 332.

[0044] Advantages of the present invention:

[0045] By utilizing a multi-axis adjustable retention system that secures expansion cards in at least three directions, the present invention significantly improves the card's tolerance to acceleration (force) when inserted into the slot, thereby preventing the system from freezing due to stress. Furthermore, by adding position adjustment features to each retaining element, the present invention can better accommodate expansion cards of various sizes and external profiles.

[0046] The above is only a preferred embodiment of the present invention and is not intended to limit the scope of the present invention.
