This disclosure can be implemented in many different forms and is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.

[0028] These embodiments are provided to make the disclosure thorough and complete, and to fully express the scope of the disclosure to those skilled in the art. It should be noted that, unless otherwise specifically stated, the relative arrangement of components and steps, material composition, numerical expressions, and values ​​set forth in these embodiments should be interpreted as exemplary only and not as limiting.

[0029] It should be noted that, in the description of this disclosure, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," and "outer," etc., indicating orientation or positional relationship, are only for the convenience of describing this disclosure and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this disclosure. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0030] Furthermore, the terms "first," "second," and similar terms used in this disclosure do not indicate any order, quantity, or importance, but are merely used to distinguish different parts. "Vertical" is not strictly vertical, but within the permissible margin of error. "Parallel" is not strictly parallel, but within the permissible margin of error.

[0033] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0034] Circuit boards are fixed inside electronic devices with screws. During the installation or removal of circuit boards, screws often fall out. Due to the small gaps inside electronic devices, it is not easy to find the fallen screws, and it may even be necessary to disassemble part of the structure inside the electronic device, resulting in unnecessary workload.

[0035] The inventors of this disclosure have discovered a connecting device that can include a ring body and a target structure. The ring body can be disposed on a first structural member and has a connecting hole. A fixing member can be inserted into the connecting hole from one side of the first structural member and connected to a second structural member disposed on the other side of the first structural member. Thus, the connection between the first and second structural members can be achieved through the cooperation of the fixing member and the connecting device. The target structure is disposed on the periphery of the ring body and can retract as the fixing member is inserted into the connecting hole. The target structure has a locking part. When the fixing member moves a target distance in the direction opposite to its insertion direction, the fixing member can detach from the second structural member. However, at this time, the locking part locks the fixing member in a locking manner, preventing it from detaching from the connecting device. The connecting device remains connected to the first structural member, thereby reducing the probability of the fixing member falling off and being lost. The first structural member can be a circuit board, expansion card, or other board, and the second structural member can be a housing that accommodates the connecting device and the first structural member.

[0036] First aspect

[0037] This disclosure provides a connecting device 10, see [link]. Figures 1 to 8 The connecting device 10 may include: a ring body 11 and a target structure 12. The ring body 11 is provided with a connecting hole 111 for inserting the fastener 20. The target structure 12 is disposed on the periphery of the ring body 11 and retracts as the fastener 20 is inserted into the connecting hole 111. The target structure 12 is provided with a snap-fit ​​part 121, which is used to snap-fit ​​and limit the fastener 20 when the fastener 20 moves a target stroke in a direction opposite to the insertion direction of the fastener 20.

[0038] The ring 11 can be detachably or non-detachably connected to the first structural component (such as the board body 41 of the circuit board 40 described below). For example, the first structural component has a through hole (such as the fixing hole 411 described below), and the ring 11 is fixed in the through hole of the first structural component by interference fit. When a pulling or pushing force is applied to the ring 11 in the same direction as the depth of the through hole, the ring 11 can be detached from the first structural component, thereby achieving a detachable connection between the ring 11 and the first structural component. Alternatively, the first structural component has a through hole, and the ring 11 is welded into the through hole, thereby achieving a fixed connection between the ring 11 and the first structural component. The center of the ring 11 and the center of the through hole may coincide or not. The periphery of the fastener 20 may have an elastic layer so that it can be fixedly connected to the connecting hole 111 by interference fit, and the fastener 20 can be pulled away from the connecting hole 111 to detach it from the connecting hole 111. The fastener 20 may also be... Figures 4 to 8 The bolt shown is designed to be connected by a threaded fit to the inner wall of the connecting hole 111, and the fastener 20 can be disengaged from the connecting hole 111 by rotating the fastener 20; the connection between the fastener 20 and the connecting hole 111 can also be in other ways, which are not specifically limited here.

[0039] The target structure 12 may be disposed along the connecting hole 111 of the ring body 11 and connected to at least one of the inner edge, outer edge, or inner and outer edges of the ring body 11, so as to be located on the periphery of the ring body 11; it may be connected to the ring body 11 by integral molding, welding, or other connection methods. The target structure 12 has a snap-fit ​​portion 121. During the process of the fastener 20 being inserted from one side of the first structural member along the connecting hole 111 and connecting with the second structural member (target member 50 as described below) stacked on the other side of the first structural member, the fastener 20 presses the target structure 12 towards the first structural member, so that the target structure 12 gradually shrinks as the fastener 20 is inserted. After the fastener 20 has finished extending into the connecting hole 111 and the target structure 12 has finished shrinking, the first structural member and the second structural member are connected by the cooperation of the fastener 20 and the connecting device 10. The two structural components are connected together. Then, as the fixing member 20 moves in the direction opposite to the direction in which it is inserted into the connecting hole 111, the fixing member 20 gradually releases the compression on the target structure 12, causing the target structure 12 to switch from a contracted state to an extended state. After the target structure 12 is fully extended, the fixing member 20 moves the target distance and separates from the second structural component. The fixing member 20 is then locked by the locking part 121 of the target structure 12, preventing it from further disengaging from the connecting hole 111. At this point, the ring body 11 remains connected to the first structural component. Here, the target distance is related to the amount of extension of the target structure 12; thus, different target structures 12 can be set to achieve different target distance settings.

[0040] The first structural component can be a circuit board 40, an expansion card, or other board components, while the second structural component can be a housing connection device 10, the outer shell of the first structural component, or other similar components.

[0041] In one example, the laptop computer includes: a display end with a display screen and a system end with an input area (such as an input keyboard, touchpad, etc.). When a user inputs information through the input area, the content displayed on the display screen can be changed. A circuit board 40 (such as a first structural component) within the system end that converts the input information into display information is positioned opposite the system end casing (such as a second structural component). See [reference needed]. Figures 1 to 8The connecting device 10 may include: a ring body 11 and a target structure 12. The ring body 11 is provided with a connecting hole 111 for inserting a fastener 20. The inner wall of the connecting hole 111 is provided with a first thread along the depth direction of the connecting hole 111. The fastener 20 is a bolt and has a second thread adapted to the first thread. The target structure 12 is disposed on the periphery of the ring body 11, and the target structure 12 retracts towards the target structure 12 as the fastener 20 is inserted into the connecting hole 111. The target structure 12 is provided with a snap-fit ​​part 121, which is used to snap-fit ​​limit the fastener 20 when the fastener 20 moves a target stroke in the opposite direction to the direction in which the fastener 20 is inserted into the connecting hole 111.

[0042] In this embodiment, the connecting device 10 may include a ring body 11 and a target structure 12. The ring body 11 may be disposed on a first structural member and has a connecting hole 111. The target structure 12 may be disposed on the periphery of the ring body 11 and has a snap-fit ​​portion 121. The fixing member 20 may be inserted into the connecting hole 111 from one side of the first structural member and connected to a second structural member on the other side of the first structural member. The target structure 12 may retract as the fixing member 20 is inserted into the connecting hole 111, and retract when the fixing member 20 has finished extending into the connecting hole 111 and the target structure 12 has finished retracting. After the process, the first structural member and the second structural member are connected together by the cooperation of the fastener 20 and the connecting device 10; and when the fastener 20 moves a target distance in the direction opposite to the direction in which the fastener 20 is inserted into the connecting hole 111 so that the fastener 20 is detached from the second structural member but is still connected to the connecting hole 111, the locking part 121 locks the fastener 20 so that the fastener 20 is still connected to the connecting device 10, and the connecting device 10 is connected to the first structural member, thereby reducing the probability that the fastener 20 will detach from the first structural member and fall out and be lost.

[0043] In some embodiments, see Figures 1 to 8 The target structure 12 includes a plurality of elastic rods 122. The first end of each elastic rod 122 is elastically connected to the periphery of the ring body 11, and the plurality of elastic rods 122 are located on the same side of the ring body 11. Each elastic rod 122 has a hook 123 at its second end away from the first end, and the hooks 123 of the plurality of elastic rods 122 cooperate to form a locking part 121.

[0044] The first end of the elastic rod 122 is elastically connected to the ring 11, so that the second end of the elastic rod 122 moves toward the first structural member when subjected to the compressive force of the fixing member 20 toward the first structural member, thereby compressing the target structure 12, and can return to its original shape as the fixing member 20 moves in the opposite direction to the direction in which the fixing member 20 is inserted into the connecting hole 111; a plurality of elastic rods 122 are connected to the periphery of the ring 11, and each elastic rod 122 has a hook 123 at its second end away from the first end, so that the second ends of the plurality of elastic rods 122 can be compressed synchronously under the compressive force of the fixing member 20 toward the first structural member, and when the fixing member 20 moves a target distance in the opposite direction to the direction in which the fixing member 20 is inserted into the connecting hole 111, the plurality of hooks 123 can engage with the surface of the fixing member 20 facing away from the first structural member.

[0045] The multiple elastic rods 122 can be evenly distributed around the circumference of the ring 11 to make the insertion of the fastener 20 into the connection hole 111 more stable, and the movement of the fastener 20 in the opposite direction to the direction in which the fastener 20 is inserted into the connection hole 111 is also more stable.

[0046] In some embodiments, see Figures 1 to 8 The elastic rod 122 includes a connecting end 1221 and a rod body 1222. One end of the rod body 1222 is connected to the periphery of the ring body 11 through the connecting end 1221, and the other end of the rod body 1222 is misaligned with the connecting end 1221. The hook 123 is provided at the end of the rod body 1222 away from the connecting end 1221, and has an angle with the rod body 1222 to form a snap-fit ​​area 1223. When the fixing member 20 moves the target stroke in a direction opposite to the insertion direction of the fixing member 20, the snap-fit ​​areas 1223 of the multiple elastic rods 122 cooperate to snap-fit ​​limit the fixing member 20.

[0047] The other end of the rod 1222 is misaligned with the connecting end 1221, which allows the hook 123 connected to the other end of the rod 1222 to be misaligned with the connecting end 1221. This makes it easier for the fixing member 20 to press the target structure 12 towards the first structural member. The angle between the hook 123 and the rod 1222 can be set such that the surface of the hook 123 engaging with the fixing member 20 is parallel to the surface of the ring 11 corresponding to the elastic rod 122. This results in a larger contact area between the hook 123 and the fixing member 20 when the hook 123 engages with the fixing member 20, thus making the connection between the fixing member 20 and the first structural member more stable.

[0048] In some embodiments, see Figure 1The connecting end 1221 is plate-shaped and is vertically connected to the end surface of the ring body 11 along the axial direction; the rod body 1222 is inclined to the connecting end 1221 so that the other end of the rod body 1222 is misaligned with the connecting end 1221.

[0049] The connecting end 1221 can be plate-shaped and is perpendicularly connected to the end surface of the ring 11 in the axial direction by welding or other means. The rod 1222 is inclined to the connecting end 1221, so that the angle and distance between the rod 1222 and the first structural member are small. The small angle makes it easier for the fixing member 20 to press the target structure 12 towards the first structural member, and the small distance makes it faster for the fixing member 20 to connect to the second structural member.

[0050] In some embodiments, see Figures 1 to 8 The multiple elastic rods 1222 are inclined along the same circumferential direction of the ring 11 and are evenly distributed. In this way, not only can the visual effect of the connecting device 10 be improved, but the process of the fixing member 20 pressing the multiple elastic rods 122 against the first structural member is also more stable, and the process of the fixing member 20 moving in the opposite direction to the direction of the fixing member 20 being inserted into the connecting hole 111 is also more stable.

[0051] Second aspect

[0052] This disclosure provides a connection component 30, see [link] Figure 4 The connecting assembly 30 may include a bolt and a connecting device 10. The connecting device 10 may include a ring 11 and a target structure 12. The ring 11 is provided with a connecting hole 111 for bolt insertion. The target structure 12 is disposed on the periphery of the ring 11 and shrinks as the bolt is inserted into the connecting hole 111. The target structure 12 is provided with a snap-fit ​​part 121, which is used to snap-fit ​​and limit the bolt when the bolt moves a target stroke in the direction opposite to the bolt insertion direction.

[0053] The inner wall of the connecting hole 111 can be provided with a first thread along the depth direction of the connecting hole 111 to adapt to the second thread on the bolt. When the fixing member 20 extends into the connecting hole 111 and is connected to the second structural member, the fixing member 20 is threadedly connected to the connecting hole 111 and the second structural member. The concave and convex arrangement of the thread can make the fixing member 20, the connecting hole 111 and the second structural member have a limiting force in the depth direction of the connecting hole 111, so as to improve the relative fixing effect between the fixing member 20, the first structural member and the second structural member.

[0054] It should be noted that the connecting device in the connecting component provided in this disclosure is similar to the connecting device embodiments described above, and has similar beneficial effects. For technical details not disclosed in the connecting component embodiments of this disclosure, please refer to the description of the connecting device embodiments in this disclosure for understanding; further details will not be repeated here.

[0055] Third aspect

[0056] This disclosure provides a circuit board 40, see [link to relevant documentation] Figures 5 to 8 The circuit board 40 may include a board body 41 and a plurality of connecting devices 10. The board body 41 is provided with a plurality of fixing holes 411. The plurality of connecting devices 10 are respectively disposed in the plurality of fixing holes 411. The connecting device 10 includes a ring body 11 and a target structure 12. The ring body 11 is provided with a connecting hole 111 for inserting the fixing member 20. The target structure 12 is disposed on the periphery of the ring body 11 and shrinks as the fixing member 20 is inserted into the connecting hole 111. The target structure 12 is provided with a snap-fit ​​part 121. The snap-fit ​​part 121 is used to snap-fit ​​limit the fixing member 20 when the fixing member 20 moves a target stroke in a direction opposite to the insertion direction of the fixing member 20. When the fixing member 20 is inserted into the connecting hole 111, the fixing member 20 can also be detachably connected to the target member 50.

[0057] Multiple fixing holes 411 on the board 41 can be connected one-to-one with multiple connecting devices 10. Multiple fasteners 20 can then pass through the connecting holes 111 of the multiple connecting devices 10 and connect to the target component 50, thus creating multiple connection points between the board 41 and the target component 50 for better relative fixation. The target component 50 can be a housing for the connecting devices 10, the outer shell of the circuit board 40, etc.

[0058] It should be noted that, Figure 5 To prepare a structural diagram for inserting the fastener 20, Figure 6 This is a schematic diagram of the structure of the target structure 12 being compressed during the insertion of the fastener 20 into the connecting hole 111. Figure 7 This is a schematic diagram showing the structure after the plate 41 and the target part 50 are connected by the fastener 20 and the connecting device 10. Figure 8 This is a schematic diagram of the structure after the fixing member 20 has moved a target distance in the opposite direction to the direction in which the fixing member 20 is inserted into the connecting hole 111. At this time, the target member 50 is separated from the fixing member 20, but the fixing member 20 is still connected to the plate 41.

[0059] In this embodiment, the circuit board 40 may include: a board body 41 and a plurality of connecting devices 10. The board body 41 is provided with a plurality of fixing holes 411. The plurality of connecting devices 10 are respectively disposed in the plurality of fixing holes 411. The connecting device 10 may include: a ring body 11 and a target structure 12. The ring body 11 may be disposed on the board body 41 and is provided with a connecting hole 111. The target structure 12 may be disposed on the periphery of the ring body 11 and has a snap-fit ​​portion 121. The fixing member 20 may be inserted into the connecting hole 111 from one side of the board body 41 and connected to the target member 50 on the other side of the board body 41. The target structure 12 may retract as the fixing member 20 is inserted into the connecting hole 111. After the process of the fastener 20 extending into the connecting hole 111 is completed and the target structure 12 has completed the shrinkage process, the plate 41 and the target part 50 are connected together by the cooperation of the fastener 20 and the connecting device 10. Furthermore, when the fastener 20 moves a target distance in the opposite direction to the direction in which the fastener 20 is inserted into the connecting hole 111 so that the fastener 20 is detached from the target part 50 but is still connected to the connecting hole 111, the locking part 121 locks the fastener 20 so that the fastener 20 is still connected to the connecting device 10, and the connecting device 10 is connected to the plate 41, thereby reducing the probability that the fastener 20 will detach from the plate 41 and fall out and be lost.

[0060] In some embodiments, see Figures 5 to 8 The fixing hole 411 is provided with a connector 42, which is annular and is connected to the inner wall of the fixing hole 411 and the outer wall of the ring 11 respectively. The axial end surface of the connector 42 forms the connection area of ​​the connection end 1221 of the target structure 12.

[0061] The connector 42 can be an adhesive. The adhesive can not only connect the inner wall of the fixing hole 411 of the circuit board 40 and the outer wall of the ring 11, but also bond it to the connection end 1221 of the target structure 12, so that the connection area between the connector 10 and the board 41 is larger and the connection is stronger.

[0062] In some embodiments, see Figures 5 to 8 The surface of the connecting end 1221 corresponding to the outer ring wall of the connecting body 42 is flush with the outer ring wall of the connecting body 42. That is to say, the orthographic projection of the connecting end 1221 onto the plate 41 is misaligned with the plate 41, thereby reducing the probability of the plate 41 being squeezed and damaged during the process of the fastener 20 connecting the plate 41 and the target part 50.

[0063] It should be noted that the connection device in the circuit board provided in this disclosure is similar to the connection device embodiments described above, and has similar beneficial effects. For technical details not disclosed in the circuit board embodiments of this disclosure, please refer to the description of the connection device embodiments in this disclosure; further details will not be repeated here.

[0064] Fourth aspect

[0065] This disclosure provides an electronic device 60, see [link to document]. Figure 9 The electronic device 60 may include a target component 50 and a circuit board 40. The circuit board 40 may include a board body 41 and multiple connecting devices 10. The board body 41 is provided with multiple fixing holes 411. The multiple connecting devices 10 are respectively disposed in the multiple fixing holes 411. Each connecting device 10 includes a ring body 11 and a target structure 12. The ring body 11 is provided with a connecting hole 111 for inserting the fixing component 20. The target structure 12 is disposed on the periphery of the ring body 11 and retracts as the fixing component 20 is inserted into the connecting hole 111. The target structure 12 is provided with a snap-fit ​​part 121, which is used to snap-fit ​​and limit the fixing component 20 when the fixing component 20 moves a target stroke in a direction opposite to the insertion direction of the fixing component 20. When the fixing component 20 is inserted into the connecting hole 111, the fixing component 20 can also be detachably connected to the target component 50.

[0066] Electronic device 60 can be a laptop computer, desktop computer, server, or other similar device. Target component 50 can be the housing of the connecting device 10, circuit board 40, or similar components.

[0067] In this embodiment, the electronic device 60 may include a target component 50 and a circuit board 40. The circuit board 40 may include a board body 41 and multiple connecting devices 10. The board body 41 is provided with multiple fixing holes 411. The multiple connecting devices 10 are respectively disposed in the multiple fixing holes 411. The connecting device 10 may include a ring body 11 and a target structure 12. The fixing component 20 can be inserted into the connecting hole 111 in the center of the ring body 11 from one side of the board body 41 and connected to the target component 50 on the other side of the board body 41. After the fixing component 20 is separated from the target component 50, if it still wants to be separated from the board body 41, the snap-fit ​​part 121 of the target structure 12 snaps the fixing component 20, so that the fixing component 20 is still connected to the connecting device 10, and the connecting device 10 is connected to the board body 41, thereby reducing the probability that the fixing component 20 will fall off the circuit board 40 and be lost.
