[0002] Some existing electronic devices (such as servers and computers) may need to be compatible with different models of external devices (such as SSD cards). In some existing solutions, external devices on electronic devices require tools to be installed and removed, which is inconvenient. Utility Model Content

[0003] This application provides an adapter bracket and circuit board assembly to solve the problem of inconvenient operation when replacing external devices in existing electronic devices.

[0004] The adapter bracket provided in the embodiments of this application includes a bracket member and an adapter member. The bracket member has a receiving groove extending along a first direction, and the receiving groove includes a first groove segment and a second groove segment communicating along the first direction. The first groove segment and the second groove segment are adapted to jointly receive a first type of target member, and the first groove segment is adapted to receive a second type of target member. The dimension of the first type of target member along the first direction is larger than the dimension of the second type of target member along the first direction. The adapter member is configured to be detachably mounted on the second groove segment and to limit the second type of target member received in the first groove segment near one end of the second groove segment.

The column segment protrudes from the support platform toward the bottom surface of the receiving groove. The locking protrusion protrudes from the column segment toward the first groove segment along the first direction and is configured to lock one end of the second target member along the first direction toward the second groove segment between the locking protrusion and the support platform.

[0008] In one possible implementation, the adapter further includes an operating part disposed on the side of the clamping part away from the first groove segment along the first direction. The operating part can be pressed and deformed under the action of external force to lift the second target member, so that the second target member elastically pushes open the clamping protrusion and disengages from the clamping part.

The two ends of the operating part are a support end and a pressing end, respectively. The support end is located on the side of the operating part close to the crossbeam along the first direction. The surface of the support end away from the bottom surface of the receiving groove is flush with the surface of the support platform to jointly support the end of the second target part close to the adapter along the first direction. The pressing end is located on the side of the operating part away from the crossbeam along the first direction. The pressing end can move towards the bottom surface of the receiving groove under the action of external force, so that the support end moves away from the bottom surface of the receiving groove and lifts the second target part.

[0011] In one possible implementation, the support member includes a bottom wall, two side walls and a front wall. The bottom wall extends along a first direction, and the two side walls are respectively connected to the two sides of the bottom wall along a second direction. The two ends of the front wall along the second direction are respectively connected to the ends of the two side walls along the first direction away from the second groove segment. The bottom wall, the two side walls and the front wall together form a receiving groove.

The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0068] Some embodiments of this application are described in detail. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0069] Example

[0070] See Figures 1 to 3 This embodiment provides a circuit board assembly 1000, which includes a circuit board 100, an adapter bracket 200, and a target component.

[0071] The circuit board 100 has a connector 101 for connecting the electrical terminal 111 of the target component to electrically connect the target component to the circuit board 100.

[0072] The adapter bracket 200 is connected to the circuit board 100 and is used to mount the target component.

[0073] In this embodiment, the target component can be either a first target component 10 or a second target component 11. The first target component 10 and the second target component 11 are two different models of SSD cards. Both the first target component 10 and the second target component 11 have power terminals 111 adapted to the connector 101. In other embodiments, the target component can also be an external device such as a memory card or memory module. The length of the first target component 10 along the first direction X is greater than the length of the second target component 11 along the first direction X.

[0074] In this embodiment, the first direction X intersects the second direction Y at an angle or perpendicularly, and the third direction Z is perpendicular to the plane formed by the first direction X and the second direction Y. For example, the first direction X can be the length direction of the adapter bracket 200, the second direction Y can be the width direction of the adapter bracket 200, and the third direction Z can be the thickness direction of the adapter bracket 200.

[0075] See Figure 3 (The dotted line in the figure additionally shows the second type of target component 11.) In this embodiment, the adapter bracket 200 also includes a first heat dissipation pad 22, a second heat dissipation pad 23, and a heat dissipation plate 24. When installing the first type of target component 10, the first heat dissipation pad 22 is disposed between the first type of target component 10 and the bottom surface of the receiving groove 16 along the second direction Y, so that the first type of target component 10 is thermally connected to the bracket component 12. The length of the first heat dissipation pad 22 along the first direction X is less than the length of the first type of target component 10 along the first direction X. The heat dissipation plate 24 is connected to the side of the first type of target component 10 away from the bottom surface of the receiving groove 16 along the third direction Z. The heat dissipation plate 24 is spaced apart from the first type of target component 10. The second heat dissipation pad 23 is disposed between the first type of target component 10 and the heat dissipation plate 24 along the third direction Z, so that the first type of target component 10 is thermally connected to the heat dissipation plate 24. The length of the second heat dissipation pad 23 along the first direction X is less than the length of the portion of the first type of target component 10 received in the receiving groove 16 along the first direction X.

[0076] When installing the second target component 11, a first heat dissipation pad 22 is disposed along the second direction Y between the second target component 11 and the bottom surface of the receiving groove 16, so that the second target component 11 is thermally connected to the support component 12. The length of the first heat dissipation pad 22 along the first direction X is less than the length of the portion of the second target component 11 disposed in the receiving groove 16 along the first direction X. A heat dissipation plate 24 is connected to the side of the second target component 11 away from the bottom surface of the receiving groove 16 along the third direction Z. The heat dissipation plate 24 is spaced apart from the second target component 11. A second heat dissipation pad 23 is disposed along the third direction Z between the second target component 11 and the heat dissipation plate 24, so that the second target component 11 is thermally connected to the heat dissipation plate 24. The length of the second heat dissipation pad 23 along the first direction X is less than the length of the portion of the second target component 11 disposed in the receiving groove 16 along the first direction X.

[0077] See Figures 2 to 5 In this embodiment, the adapter bracket 200 includes a bracket member 12 and an adapter member 300. The bracket member 12 has a receiving groove 16 extending along a first direction X. The receiving groove 16 includes a first groove segment 161 and a second groove segment 162 communicating along the first direction X. The first groove segment 161 and the second groove segment 162 are adapted to jointly receive a first target member 10, and the first groove segment 161 is adapted to receive a second target member 11. The dimension of the first target member 10 along the first direction X is larger than the dimension of the second target member 11 along the first direction X. The adapter member 300 is configured to be detachably mounted to the second groove segment 162 and to limit the second target member 11 received in the first groove segment 161 near the end of the second groove segment 162.

[0078] In this embodiment, the adapter 300 can be detached from the adapter bracket 200 to change the receiving groove 16 from a state adapted to the second target member 11 to a state adapted to the first target member 10.

[0079] When installing the second target component 11, the adapter 300 is installed and fixed in the second groove section 162. The groove wall of the receiving groove 16 away from the second groove section 162 along the first direction X and the side of the adapter 300 close to the first groove section 161 along the first direction X together limit the second target component 11, so as to restrict the displacement of the second target component 11 along the first direction X.

[0080] When installing the first target component 10, the adapter 300 is removed from the second groove section 162, and the groove walls on both sides of the receiving groove 16 along the first direction X jointly limit the first target component 10 along the first direction X, so as to restrict the displacement of the first target component 10 along the first direction X.

[0081] In this embodiment, the bracket 12 has a first groove segment 161 and a second groove segment 162 distributed along a first direction X. The first groove segment 161 and the second groove segment 162 are adapted to the first type of target component 10. The adapter 300 is detachably disposed on the second groove segment 162 so that the bracket 12 can be fitted with the second type of target component 11 adapted to the first groove segment 161. During the disassembly and assembly process, it is not necessary to remove the adapter bracket 200 as a whole; only the adapter 300 needs to be removed to set different types of target components on the circuit board 100. Moreover, the disassembly process of the adapter 300 does not require the assistance of tools such as screwdrivers, making it highly versatile and convenient to operate.

[0082] See Figures 4 to 6 In this embodiment, the adapter 300 includes a base 17 and a locking portion 18. The base 17 has a crossbeam 171 extending along a first direction X towards the first groove segment 161. The locking portion 18 includes a support platform 181, a column segment 182, and a locking protrusion 183. The support platform 181 is disposed on the side of the crossbeam 171 away from the bottom surface of the receiving groove 16 along a third direction Z. The column segment 182 protrudes from the support platform 181 along a third direction Z towards the bottom surface of the receiving groove 16. The locking protrusion 183 protrudes from the side of the column segment 182 facing the first groove segment 161 along the first direction X and is configured to lock one end of the second target member 11 near the second groove segment 162 along the first direction X between the locking protrusion 183 and the support platform 181.

[0083] In this embodiment, the adapter 300 is integrally made of an elastic material, such as an elastic plastic material. When the clamping part 18 is pressed, the crossbeam 171 can elastically twist and drive the clamping part 18 to retract in the first direction X away from the first groove segment 161.

[0084] When installing the second target part 11, firstly, insert the end of the second target part 11 away from the second groove segment 162 along the first direction X at an angle to the side wall 14 of the receiving groove 16 on the side away from the second groove segment 162 along the first direction X. Then, screw the end of the second target part 11 close to the second groove segment 162 along the first direction X to the clamping part 18. In this way, the clamping part 18 can be elastically retracted under pressure to fix the end of the second target part 11 close to the second groove segment 162 along the first direction X to the clamping part 18.

[0085] In this embodiment, the snap-fit ​​protrusion 183 has a guide slope 183a along the first direction X near the side of the first groove segment 161 (see... Figure 2The guide slope 183a is inclined to intersect the first direction X, so that when the second target part 11 is installed, the end of the second target part 11 near the second groove segment 162 presses against the guide slope 183a, and drives the snap-fit ​​protrusion 183 to elastically retract to the side away from the first groove segment 161, thereby snapping the second target part 11 between the snap-fit ​​protrusion 183 and the support platform 181.

[0086] In this embodiment, the base 17 includes two side portions 172, which are parallel and spaced apart along the second direction Y. The two ends of the crossbeam 171 along the second direction Y are respectively connected to the ends of the two side portions 172 along the first direction X near the first groove segment 161.

[0087] In this embodiment, the two side portions 172 are spaced apart along the second direction Y. Each side portion 172 is provided with a limiting protrusion 173 that faces the two side walls of the receiving groove 16 along the second direction Y. The limiting protrusions 173 of the two side portions 172 respectively abut against the two side walls of the receiving groove 16 along the second direction Y to limit the displacement of the adapter 300 along the second direction Y.

[0088] In this embodiment, the adapter 300 further includes an operating part 19, which is disposed on the side of the clamping part 18 away from the first groove segment 161 along the first direction X. The operating part 19 can be pressed and deformed under the action of external force to lift the second target member 11, so that the second target member elastically pushes open the clamping protrusion 183 and disengages from the clamping part 18. The middle of the operating part 19 is connected between the two side parts 172, and the middle position of the operating part 19 is connected between the two side parts 172 by a connecting rod 193. The connecting rod 193 extends along the second direction Y and is connected to the groove walls on both sides of the receiving groove 16 along the second direction Y. When the pressing end 192 of the operating part 19 is pressed, the connecting rod 193 can be elastically twisted so that the supporting end 191 turns away from the bottom surface of the receiving groove 16.

[0089] The operating part 19 has a support end 191 and a pressing end 192 at its two ends. The support end 191 is located on the side of the operating part 19 along the first direction X, close to the crossbeam 171. The surface of the support end 191 along the third direction Z, away from the bottom surface of the receiving groove 16, is flush with the surface of the support platform 181, so as to jointly support the end of the second target part 11 along the first direction X, close to the adapter 300. The pressing end 192 is located on the side of the operating part 19 along the first direction X, away from the crossbeam 171. The pressing end 192 can move along the third direction Z towards the bottom surface of the receiving groove 16 under the action of external force, so that the support end 191 moves along the third direction Z towards the side away from the bottom surface of the receiving groove 16 and lifts the second target part 11. During the lifting process, the second target part 11 abuts against the locking protrusion 183, causing the locking protrusion 183 to elastically retract along the first direction X to the side away from the first groove segment 161, thereby allowing the second target part 11 to be removed from the adapter bracket 200.

[0090] In this embodiment, the support end 191 and the pressing end 192 are distributed along the first direction X, and the thickness of the operating part 19 along the third direction Z is small, so that the thickness of the adapter bracket 200 along the third direction Z is small, and the adapter bracket 200 occupies less space when installed on the circuit board 100.

[0091] In this embodiment, the operating surface of the pressing end 192 is oriented along the third direction Z toward the side away from the bottom surface of the receiving groove 16. When the operator presses along the third direction Z, there are no parts obstructing the view, and no other tools are needed to assist in disassembling the second target part 11 during the operation, making the operation convenient.

[0092] See Figure 6 and Figure 7 In this embodiment, the support member 12 includes a bottom wall 13, two side walls 14, and a front wall 15. The bottom wall 13 extends along a first direction X. The two side walls 14 are respectively connected to the two sides of the bottom wall 13 along a second direction Y. The front wall 15 is connected to the side of the bottom wall 13 along the first direction X away from the second groove segment 162. The two ends of the front wall 15 along the second direction Y are respectively connected to the ends of the two side walls 14 along the first direction X away from the second groove segment 162. The bottom wall 13, the two side walls 14, and the front wall 15 together form a receiving groove 16.

[0093] In this embodiment, the front wall 15 has a through hole 151 (see... Figure 2 When installing the first type of target component 10, the electrical terminal 111 of the first type of target component 10 passes through the through hole 151 along the first direction X and extends out of the receiving groove 16, and is electrically connected to the connector 101. When installing the second type of target component 11, the electrical terminal 111 of the second type of target component 11 passes through the through hole 151 along the first direction X and extends out of the receiving groove 16, and is electrically connected to the connector 101.

[0094] In this embodiment, the bottom wall 13 has a first through hole 131 and a second through hole 132, which are formed in the bottom wall 13 along the second direction Y corresponding to the second groove segment 162. The adapter 300 includes a bending portion 20 and a positioning portion 21. The bending portion 20 and the positioning portion 21 are disposed on the side of the adapter 300 along the third direction Z close to the bottom surface of the receiving groove 16. The bending portion 20 corresponds to the first through hole 131. The positioning portion 21 corresponds to the second through hole 132. The bending portion 20 can pass through the first through hole 131 and extend out of the receiving groove 16, and be engaged with the bottom wall 13. The positioning portion 21 can extend into the second through hole 132 to fix the adapter 300 to the bottom wall 13, or elastically leave the second through hole 132 under the action of external force, so as to allow the adapter 300 to be removed from the bottom wall 13.

[0095] In this embodiment, when the adapter 300 is installed in the receiving groove 16, the adapter is first moved along the third direction Z to fit against the bottom wall 13, so that the bent part 20 extends into the first through hole 131 along the third direction Z, and the positioning part 21 elastically abuts against the bottom wall 13 on the side of the second through hole 132 away from the first groove segment 161 along the first direction X. Then the adapter 300 slides along the first direction X toward the first groove segment 161, so that the bent part 20 slides along the first direction X and is engaged with the bottom wall 13. The positioning part 21 moves along the first direction X to the corresponding second through hole 132 and extends into the second through hole 132 along the third direction Z. Thus, the bending part 20 abuts against the wall of the first through hole 131 along the first direction X, which is close to the wall of the first groove segment 161, and the positioning part 21 abuts against the wall of the second through hole 132 on the side away from the first groove segment 161. The bending part 20 and the positioning part 21 together restrict the movement of the adapter 300 along the first direction X and fix the adapter 300 to the bottom wall 13.

[0096] In this embodiment, the adapter 300 has a plurality of bent portions 20 and a plurality of first through holes 131 are provided on the bottom wall 13. Each bent portion 20 corresponds to a first through hole 131 and can slide along the first direction X to engage with the corresponding first through hole 131.

[0097] In this embodiment, the adapter 300 also has a handle portion 211, which is disposed on the side of the positioning portion 21 away from the bottom surface of the receiving groove 16 along the third direction Z. The handle portion 211 can drive the positioning portion 21 away from the second through hole 132 under the action of external force, so that the adapter 300 can be moved and removed along the first direction X away from the first groove segment 161.
