Description

Technical Field

[0001] This application relates to the field of electronic equipment technology, and more particularly to a fixed structure and electronic equipment. Background Technology

[0002] In electronic devices, stable connections between components are crucial for the reliable operation of the device. Components are usually connected by plug-in structures. However, due to vibrations generated when electronic devices are moved, as well as thermal expansion and contraction of materials caused by changes in ambient temperature, the connection between the two parts will gradually loosen, thus affecting the reliable operation of the electronic device.

[0003] Therefore, it is necessary to develop a fixing device that can effectively prevent the plug-in components from loosening. Utility Model Content

[0006] The gland can be fixed to a preset position of the first component by a locking mechanism;

[0007] The pressure cap is provided with an installation port. When the pressure cap is fixed to the preset position of the first component, the installation port corresponds to the position of the insertion hole on the first component, and the second component is inserted into the insertion hole through the installation port.

[0008] The clamping member is located at the mounting opening. When the second component is inserted into the insertion hole, the clamping member presses the second component together in the insertion direction.

[0009] In some alternative embodiments, the clamping element includes an elastomer disposed on the side of the gland facing the insertion hole, the elastomer being inclined relative to the axis of the insertion hole;

[0010] One end of the elastomer is connected to the inner wall of the mounting port, and the other end of the elastomer is a free end that extends toward the axis of the insertion hole.

[0011] When the second component is inserted into the socket, the other end of the elastomer presses the second component together along the insertion direction.

[0012] In some alternative embodiments, there are multiple elastomers, which are circumferentially spaced around the axis of the mounting port.

[0013] In some optional embodiments, the clamping member is a plate-shaped structure, the clamping member is disposed at the mounting opening, one end of the clamping member is rotatably connected to the inner wall of the mounting opening, and the other end of the clamping member is detachably connected to the inner wall of the mounting opening;

[0014] When the second component is inserted into the socket, the clamping member presses the second component in the insertion direction.

[0015] In some alternative embodiments, the gland has a through hole, and the locking element includes a head, a smooth rod section, and a threaded section;

[0016] The smooth section connects the head and the threaded section. The diameter of the smooth section is smaller than the diameter of the through hole, while the diameters of the threaded section and the head are larger than the diameter of the through hole.

[0017] The polished rod section is located inside the through hole, and the head and threaded sections are used to prevent the polished rod section from leaving the through hole in the axial direction.

[0018] In some alternative implementations, the bore wall region of the through hole is made of an elastic material, and the threaded segment elastically deforms the bore wall region by compressing it to pass through the through hole.

[0019] In some alternative embodiments, a retaining body is provided on the other side of the clamping member, and a slot adapted to the retaining body is provided on the inner wall of the mounting port, and the retaining body is engaged with the slot.

[0020] In some alternative embodiments, this application also provides an electronic device, which includes the above-described fixing structure, a first component, and a second component, wherein the second component is fixed to the first component by the fixing structure.

[0021] In some alternative implementations, the first component includes a circuit board and a wireless network card, the wireless network card having a socket, and the second component is a signal cable;

[0022] One end of the signal cable is electrically connected to the circuit board; the other end of the signal cable is plugged into the socket on the wireless network card.

[0023] When the signal line is plugged into the socket, the clamping member presses the other end of the signal line in the insertion direction.

[0024] In some optional embodiments, a first positioning body and a second positioning body are respectively provided on adjacent sides of the pressure cap;

[0025] When the cover is fixed to the preset position on the circuit board, the cover abuts against the top surface of the wireless network card, the first positioning body abuts against the first side of the wireless network card, and the second positioning body abuts against the second side of the wireless network card.

[0026] In the above-mentioned fixing structure, the pressure cap is fixed to the preset position of the first component by the locking member, thereby realizing the positioning and fixing of the pressure cap. At this time, the mounting port of the pressure cap can be aligned with the insertion hole in the extension direction of the insertion hole axis, so that the mounting port forms the insertion space of the second component. The second component is installed into the insertion hole on the first component through the mounting space formed by the mounting port. Then, the abutment member presses the second component along the insertion direction to prevent the second component from coming off along the insertion direction, thereby ensuring the firmness of the connection between the first component and the second component.

[0035] To make the objectives, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0036] It should be understood that the various forms of processes shown above can be used to rearrange, add, or delete steps. For example, the steps described in this application can be executed in parallel, sequentially, or in different orders, as long as the desired result of the technical solution of this application can be achieved, and this is not limited herein.

[0037] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0038] In related technologies, components are mechanically connected by plugging. Due to the lack of an external fixing structure, vibrations generated when electronic devices are moved, as well as thermal expansion and contraction of materials caused by changes in ambient temperature, will cause the connection between the two to gradually loosen and affect the reliable operation of the electronic devices.

[0039] To solve the above problems, researchers discovered that the pressure cap can be fixed to the first component first, and a channel for the insertion of the second component can be reserved on the pressure cap. After the second component is inserted into the first component, the second component can be pressed tightly by the clamping part on the pressure cap.

[0040] Combination Figure 1 and Figure 2In some embodiments, this application provides a fixing structure 10, through which the second component 30 is fixed after being inserted into the first component 20. The fixing structure 10 includes a pressure cap 11, a locking member 12, and a retaining member 13. The pressure cap 11 can be fixed to a preset position of the first component 20 by the locking member 12; the pressure cap 11 is provided with an installation port 111, and when the pressure cap 11 is fixed to the preset position of the first component 20, the installation port 111 corresponds to the position of the insertion hole on the first component 20. Specifically, the installation port 111 and the insertion hole are directly opposite each other in the axial direction of the insertion hole; the second component 30 passes through the installation port 111 and is inserted into the insertion hole; the retaining member 13 is provided at the installation port 111, and when the second component 30 is inserted into the insertion hole, the retaining member 13 presses the second component 30 along the insertion direction; the preset position is the position where the installation port 111 on the pressure cap 11 is directly opposite the position of the insertion hole on the first component 20. Figure 1 A schematic diagram of the fixed structure 10, the first component 20, and the second component 30; Figure 2 This is an exploded structural diagram of the fixed structure 10, a part of the first component 20, and the second component 30.

[0041] In the aforementioned fixing structure 10, the pressure cap 11 is fixed to the preset position of the first component 20 by the locking member 12, thereby realizing the positioning and fixing of the pressure cap 11. At this time, the mounting port 111 of the pressure cap 11 can be directly opposite the insertion hole in the extension direction of the axis of the insertion hole, so that the mounting port 111 forms the insertion space of the second component 30. The second component 30 is installed into the insertion hole on the first component 20 through the mounting space formed by the mounting port 111. Then, the abutment member 13 presses the second component 30 along the insertion direction to prevent the second component 30 from coming off along the insertion direction, thereby ensuring the firmness of the connection between the first component 20 and the second component 30.

[0042] Combination Figure 2 In some optional embodiments, the clamping member 13 includes an elastic body disposed on the side of the pressure cap 11 facing the insertion hole, and the elastic body is inclined relative to the axis of the insertion hole; one end of the elastic body is connected to the inner wall of the mounting opening 111, and the other end of the elastic body is a free end extending toward the axis of the insertion hole; when the second component 30 is inserted into the insertion hole, the other end of the elastic body presses against the second component 30 along the insertion direction. Exemplarily, the elastic member can be a spring steel sheet with elastic deformation function.

[0043] Thus, through the inclined free end structure, the elastomer can generate elastic deformation when the second component 30 is inserted into the first component 20, forming an axial clamping force, which effectively compensates for the gap changes between the first component 20 and the second component 30 caused by vibration or thermal expansion and contraction, so that the two maintain a lasting contact pressure; moreover, the elastomer can elastically compress the second component 30 to form a flexible clamping structure, so as to avoid wear caused by hard compression to the second component 30.

[0044] Furthermore, there are multiple elastic bodies, which are circumferentially spaced around the axis of the mounting port 111. This allows the multiple elastic bodies to generate greater elastic pressure, resulting in a better clamping effect of the clamping member 13 on the second component 30, further increasing the reliability of the connection between the first component 20 and the second component 30. Simultaneously, since the other end of each elastic body is a free end extending towards the axis of the insertion hole, the multiple elastic bodies can form a tapered structure, facilitating the precise insertion of the second component 30 into the first component 20 by guiding the tapered structure.

[0045] Specifically, the number of elastomers can be 2, 3, 4, 5, 6, 7, 8, 9, or 10. It should be noted that the above-mentioned number of elastomers is merely an example, and this application does not limit the number of elastomers.

[0046] Specifically, multiple elastomers are evenly distributed circumferentially around the axis of the mounting port 111.

[0047] In some alternative embodiments, the abutment 13 is a plate-shaped structure, the abutment 13 is disposed at the mounting port 111, one end of the abutment 13 is rotatably connected to the inner wall of the mounting port 111, and the other end of the abutment 13 is detachably connected to the inner wall of the mounting port 111; when the second component 30 is inserted into the insertion hole, the abutment 13 presses the second component 30 in the insertion direction.

[0048] Thus, the second component 30 is first inserted into the first component 20, and then the clamping member 13 is flipped to press the second component 30, and the other end of the clamping member 13 is fixed to the cover plate, thereby forming an axial clamping force and pressing the second component 30 in the insertion direction. This effectively compensates for the gap changes between the first component 20 and the second component 30 caused by vibration or thermal expansion and contraction, so that the two maintain a lasting contact pressure. At the same time, the clamping member 13 can form a large contact area with the second component 30, so that the pressure can be evenly released onto the second component 30, thereby avoiding stress concentration that causes wear on the contact surface of the second component 30.

[0049] In some alternative embodiments, the clamping member 13 is a plate-shaped structure. The clamping member 13 is located at the mounting port 111, and one end of the clamping member 13 is rotatably connected to the inner wall of the mounting port 111 via a rotating shaft. An elastic member is provided at the rotating shaft. One end of the elastic member is connected to the clamping member 13, and the other end of the elastic member is connected to the pressure cap 11. The elastic force released by the elastic member is used to drive the clamping member 13 to press the second component 30.

[0050] It should be noted that the structure of the clamping member 13 disclosed above is merely an example, and this application does not limit the specific structure of the clamping member 13.

[0051] Combination Figure 2 and Figure 3 In some embodiments, the pressure cap 11 has a through hole 112, and the locking member 12 includes a head 121, a smooth rod section 122, and a threaded section 123. The smooth rod section 122 is connected between the head 121 and the threaded section 123. The diameter of the smooth rod section 122 is smaller than the diameter of the through hole 112, while the diameters of the threaded section 123 and the head 121 are larger than the diameter of the through hole 112. The head 121 and the threaded section 123 are used to prevent the smooth rod section 122 from disengaging from the through hole 112 in the axial direction. Figure 3 This is a schematic diagram of the locking component 12.

[0052] Thus, the head 121 and threaded section 123 of the locking member 12 have a larger diameter, while the smooth rod section 122 located in the through hole 112 has a smaller diameter, so that the locking member 12 forms a double axial stop structure at both ends of the smooth rod section 122, so as to keep the smooth rod section 122 always within the through hole 112, thereby preventing the locking member 12 from falling off or being lost.

[0053] In some embodiments, the hole wall region of the through hole 112 is made of an elastic material, and the threaded segment 123 causes elastic deformation by pressing the hole wall region of the through hole 112 to pass through the through hole 112, so that the polished rod segment 122 can move into the through hole 112, and the head 121 and the threaded segment 123 prevent the polished rod segment 122 from leaving the through hole 112 in the axial direction.

[0054] Thus, when the locking member 12 is installed into the through hole 112 on the pressure cap 11, the threaded section 123 compresses the hole wall area of ​​the through hole 112 to generate elastic deformation, so that the diameter of the through hole 112 can be expanded radially, so that the threaded section 123 can pass through the through hole 112 and the smooth section 122 can enter the through hole 112. At this time, the elastically expanded through hole 112 returns to its original diameter, so that the larger diameter head 121 and the threaded section 123 prevent the smooth section 122 from dislodging from the through hole 112 in the axial direction, thereby preventing the locking member 12 from falling off or being lost; at the same time, by making the hole wall of the through hole 112 elastically deformable, the locking member 12 can be quickly installed into the through hole 112 on the pressure cap 11.

[0055] Furthermore, the gland 11 can be made of plastic, utilizing the elastic deformation capability of the plastic itself to form the radial deformation capability of the hole wall of the through hole 112. Alternatively, an elastic ring can be provided at the hole wall of the through hole 112. For example, the elastic ring can be made of rubber material to give the hole wall of the through hole 112 greater elastic deformation capability.

[0056] In some optional embodiments, a retaining body is provided on the other side of the abutment 13, and a slot adapted to the retaining body is provided on the inner wall of the mounting port 111. The retaining body and the slot are engaged and connected. In this way, the retaining body and the retaining body achieve the engagement connection between the abutment 13 and the cover plate. The engagement between the retaining body and the slot can adopt a sliding engagement structure. During assembly, pressing the abutment 13 can complete the locking and fixing of the abutment 13. The operation is convenient, quick and easy and saves time and effort.

[0057] In some alternative embodiments, the other end of the clamping member 13 can also be detachably connected to the inner wall of the mounting port 111 by means of a threaded structure, a pin structure, or the like.

[0058] It should be noted that the detachable fixing structures listed above are merely examples, and this application does not limit the specific structure of the detachable connection.

[0059] Combination Figure 1In some embodiments, this application also provides an electronic device, which includes the aforementioned fixing structure 10, a first component 20, and a second component 30; the second component 30 is fixed to the first component 20 by the fixing structure 10. The fixing structure 10 includes a pressure cover 11, a locking member 12, and a pressing member 13. The pressure cover 11 is fixed to a preset position of the first component 20 by the locking member 12; the pressure cover 11 is provided with an installation port 111, and when the pressure cover 11 is fixed to the preset position of the first component 20, the installation port 111 corresponds to the position of the insertion hole on the first component 20. Specifically, the installation port 111 and the insertion hole are directly opposite each other in the axial direction of the insertion hole; the second component 30 is inserted into the insertion hole through the installation port 111; the pressing member 13 is provided at the installation port 111, and when the second component 30 is inserted into the insertion hole, the pressing member 13 presses the second component 30 along the insertion direction.

[0060] Thus, the locking member 12 fixes the cover 11 to the preset position of the first component 20, thereby achieving the positioning and fixing of the cover 11. At this time, the mounting port 111 of the cover 11 is aligned with the insertion hole in the extension direction of the insertion hole axis, so that the mounting port 111 forms the insertion space of the second component 30. The second component 30 is installed into the insertion hole on the first component 20 through the mounting space formed by the mounting port 111. Then, the abutment member 13 presses the second component 30 along the insertion direction to prevent the second component 30 from coming off along the insertion direction, thereby improving the firmness of the connection between the first component 20 and the second component 30.

[0061] Combination Figure 1 In some optional embodiments, the first component 20 includes a circuit board 21 and a wireless network card 22, the wireless network card 22 having a socket, and the second component 30 is a signal line; one end of the signal line is electrically connected to the circuit board 21; the other end of the signal line is inserted into the socket on the wireless network card 22; when the signal line is inserted into the socket, the abutment 13 presses the other end of the signal line along the insertion direction.

[0062] It should be noted that a connector is also plugged into one end of the wireless network card 22, and the fixing structure 10 is fixed to the other end of the wireless network card 22. The connector is used to achieve electrical connection with the circuit board 21. When the wireless network card 22 is inserted into the connector, the other end away from the connector is prone to tilting up. When the signal line is inserted, the terminals between the wireless network card 22 and the connector are very easy to become loose, which affects the reliability of the connection.

[0063] Thus, firstly, one end of the wireless network card 22 is inserted into the connector to fix one end of the wireless network card 22; then, the other end of the wireless network card 22 is pressed and fixed by the pressure cover 11. At this time, both ends of the wireless network card 22 are fixed, thereby effectively preventing the other end of the wireless network card 22 from lifting when the signal cable is inserted into the wireless network card 22; next, the signal cable is inserted into one end of the wireless network card 22. Since the signal cable is a rear-insertion structure, the cable management step is omitted when installing the pressure cover 11, improving work efficiency; finally, the signal cable is pressed onto the wireless network card 22 by the clamping member 13.

[0064] Combination Figure 2 In some embodiments, the pressure cover 11 is provided with a first positioning body 14 and a second positioning body 15 on adjacent sides respectively; the preset position is set on the circuit board, and when the pressure cover 11 is fixed to the preset position of the circuit board 21, the pressure cover 11 abuts against the top surface of the wireless network card 22, the first positioning body 14 abuts against the first side of the wireless network card 22, and the second positioning body 15 abuts against the second side of the wireless network card 22.

[0065] Thus, by pressing the cover 11 against the top surface of the wireless network card 22, the cover 11 is positioned in the thickness direction of the wireless network card 22. By pressing the first positioning body 14 against the first side of the wireless network card 22 and the second positioning body 15 against the second side of the wireless network card 22, the cover 11 is positioned in the horizontal direction.

[0066] Furthermore, the first side and the second side are two opposite sides of the wireless network card 22, which enables the cover 11 to be positioned on the wireless network card 22 in the left-right direction. Alternatively, the first side and the second side are two adjacent sides, which enables the cover 11 to be positioned on the wireless network card 22 in the front-back direction and the left-right direction.

[0067] It should be noted that the length direction of the wireless network card 22 is the front-to-back direction, the width direction is the left-to-right direction, and the thickness direction is the thickness direction. Among these, the left-to-right and front-to-back directions of the wireless network card 22 are horizontal directions.

[0068] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
