[0002] In electronic devices, stable connections between components are crucial for the reliable operation of the device. In related technologies, components are usually connected through plug-in time. 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 components from loosening in order to optimize the component connection technology in electronic devices. Utility Model Content
[0004] This application provides a fixing device and an electronic device to at least solve the above-mentioned problems in the related art.
[0005] To achieve the above objectives, this application provides the following technical solution: a fixing device, the fixing device comprising:
[0006] The base has a support area on its top wall, on which a first component is placed, and a second component is inserted into the side of the first component away from the support area.
[0007] The pressure cap is rotatably connected to the base at a position away from the load-bearing area; wherein,

[0012] When the pressure cap is rotated to the closed state by external force, the pressure cap drives the plug of the second component to be inserted into the socket of the first component.
[0013] In one embodiment, the locking structure includes:
[0014] The snap-fit body protrudes outward in the horizontal direction from the front or rear side wall of the base;
[0015] The elastic side plate is vertically installed on the corresponding side wall of the pressure cap and has a snap-fit hole that is compatible with the snap-fit body.
[0016] in,
[0017] When the gland is in the closed state, the snap-fit body snaps into the snap-fit hole.
[0018] In one embodiment, the snap-fit body is a wedge-shaped block, the inclined surface of the wedge-shaped block forms the top wall of the wedge-shaped block, and the wedge-shaped block slides into the snap-fit hole through the inclined surface.
[0019] In one embodiment, the pressure cap is rotatably connected to the base via a pivot.

Detailed Implementation
[0038] 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.
[0039] 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.
[0040] 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.
[0041] In related technologies, components are typically connected via mating. This type of connection lacks external restraint mechanisms, making the mating points prone to slight displacement when the equipment is subjected to vibration or temperature changes. This is especially true for signal cable connectors, where the plug and socket rely solely on friction for connection; prolonged use can lead to wear on the metal contact surfaces and poor contact. Traditional reinforcement methods often involve adding tape for fixation after mating, but these methods are difficult to disassemble and cannot be reused.
[0042] In order to solve the above-mentioned problems in the related technologies, this application provides an optional solution: using a rotatable pressure cap as a dynamic constraint component, which, together with a rigid base, forms an enclosed fixed space.
[0043] Therefore, combining Figure 1 and Figure 2 This application provides a technical solution for a fixing device 10, which includes a base 11 and a pressure cover 12. The top wall of the base 11 has a bearing area 111, on which a first component 20 is placed. A second component 30 is inserted into the side of the first component 20 opposite to the bearing area 111. The pressure cover 12 is rotatably connected to the base 11 at a position away from the bearing area 111. When the pressure cover 12 is in the closed state, both the first component 20 and the second component 30 are located between the base 11 and the pressure cover 12. The pressure cover 12 rotates to press against the second component 30, and the pressure cover 12 and the base 11 are locked and fixed by a locking structure 14. Figure 1 This is a schematic diagram of the structure of the fixing device 10, the first component 20, the second component 30, and the fixing base 50 when the pressure cap is in the open state. Figure 2 This is a structural diagram of the base 11, positioning component 13, bracket 15, and welding foot 16.
[0044] In the aforementioned fixing device 10, the first component 20 is supported by the base 11, and the pressure cover 12 is rotatably connected to the base 11 at a location away from the support area 111. When the pressure cover 12 is closed, the first component 20 and the second component 30 are securely clamped between the base 11 and the pressure cover 12, and the pressure cover 12 presses against the second component 30. The locking structure 14 securely locks the pressure cover 12 and the base 11, effectively resisting the vibration of electronic equipment movement and the effects of thermal expansion and contraction caused by temperature changes. This greatly reduces the risk of loosening of the component connection, ensuring that the first component 20 and the second component 30 always maintain a tight and stable connection, and significantly improving the stability and reliability of the connection between the first component 20 and the second component 30.
[0045] It is understood that the first component 20 and the second component 30 can be mechanically connected by plugging in; or, the first component 20 and the second component 30 can be electrically connected by plugging in; or, the first component 20 and the second component 30 can be both electrically and mechanically connected by plugging in.
[0046] In some alternative embodiments, a recessed area is provided on the top wall of the base 11, which forms a bearing area 111.
[0047] In some alternative embodiments, a portion of the top wall of the base 11 forms a load-bearing area 111.
[0048] In some alternative embodiments, a raised area is provided on the top wall of the base 11, which forms a bearing area 111.
[0049] It should be noted that the above-described methods of forming the bearing area 111 are merely examples, and this application does not limit the specific method of forming the bearing area 111.
[0050] In some alternative embodiments, the cover 12 is rotatably connected to the base 11 via a pivot; thus, the pivot provides the cover 12 with a single degree of rotational freedom to ensure the accuracy of the rotation trajectory of the cover 12, so as to ensure that the cover 12 can accurately close to the base 11.
[0051] Preferably, a bracket 15 is provided on the top wall of the base 11 at a position away from the bearing area 111. There are two rotating shafts, which are fixedly connected to the opposite sides of the cover 12. Each rotating shaft is rotatably connected to the bracket 15, and the two rotating shafts can support the stable rotation of the cover 12.
[0052] It is understandable that when the cover 12 is in the closed state, the top wall of the base 11 abuts against the inner wall of the cover 12, and the cover 12 presses against the second component 30 with a predetermined pressure, thereby ensuring that the pressure of the cover 12 on the second component 30 remains stable, so as to avoid the cover 12 rotating excessively and causing excessive compression of the second component 30, thereby damaging the second component 30.
[0053] In some alternative embodiments, the pressure cap 12 is rotatably connected to the base 11 by a hinge or latch.
[0054] It should be noted that the above-described methods of rotational connection between the cover 12 and the base 11 are merely examples, and this application does not limit the specific methods of rotational connection between the cover 12 and the base 11.
[0055] In some embodiments, please combine Figure 1 and Figure 2 The base 11 is provided with a positioning element 13, which is located in the bearing area 111. The first component 20 is provided with a positioning groove 21 that is adapted to the positioning element 13, and the first component 20 is positioned in the bearing area 111 by the positioning element 13. For example, the positioning element 13 can be a cylindrical structure.
[0056] Thus, the positioning member 13 and the positioning groove 21 can constrain the first component 20 in the horizontal direction to prevent the first component 20 from moving in the horizontal direction and to achieve the positioning of the first component 20.
[0057] Preferably, when the bearing area 111 is a recessed area, the positioning member 13 is a positioning post, and the side wall of the positioning post abuts against the side wall of the bearing area 111, the bottom end of the positioning post is fixedly connected to the bottom wall of the bearing area 111, and the first component 20 is positioned in the bearing area 111 by the positioning groove 21 and the positioning post.
[0058] In some embodiments, please combine Figure 1 and Figure 3 The pressure cap 12 has a slot 121 on the side facing the first component 20. The shape of the slot 121 is adapted to the shape of the plug of the second component 30. The pressure cap 12 is engaged with the second component 30 through the slot 121. When the pressure cap 12 is rotated to the closed state by external force, the pressure cap 12 drives the plug of the engaged second component 30 to be inserted into the socket of the first component 20. Figure 3 This is a schematic diagram of the structure of the second component 30.
[0059] Thus, when the plug and socket are first connected, the plug of the second component 30 is first snapped into the slot 121 to fix and position the plug. Then, external force is applied to the cover 12 to rotate the cover 12 to the closed state, so as to drive the plug of the second component 30 into the socket of the first component 20. When the plug and socket are connected in subsequent times, the plug and socket can be directly separated or connected by rotating the cover 12 to open or close, making the operation convenient and quick.
[0060] It is understood that the slot 121 is a recessed structure provided on the inner wall of the cover 12, which can be formed by injection molding or machining. The outline of the recessed structure is consistent with the outline of the plug of the second component 30 so that the plug can be held and fixed in the slot 121. The external force drive is the operating force applied to the cover 12 and causing the cover 12 to rotate around the axis of the rotating shaft. Specifically, the external force can be achieved by manual pressing.
[0061] In some embodiments, please combine Figure 1 The locking structure 14 includes a snap-fit body 141 and an elastic side plate 142. The snap-fit body 141 protrudes outward along the axis of the rotating shaft on the side wall of the base 11. The elastic side plate 142 is vertically disposed on the corresponding side wall of the pressure cover 12 and has a snap-fit hole 143 adapted to the snap-fit body 141. When the pressure cover 12 is in the closed state, the snap-fit body 141 snaps into the snap-fit hole 143.
[0062] Thus, when the pressure cap 12 rotates to the closed state, the elastic side plate 142 elastically bends outward after contacting the locking body 141, causing the locking body 141 to gradually slide into the locking hole 143. As the pressure cap 12 continues to press down, the elastic side plate 142 returns to its original shape after the locking body 141 is fully inside the locking hole 143, at which point the inner wall of the locking hole 143 and the outer surface of the locking body 141 form surface contact. The engagement between the locking body 141 and the locking hole 143 achieves self-locking through elastic deformation, maintaining the fixed state of the pressure cap 12 and the base 11 without the need for additional external force.
[0063] Preferably, there are two snap-fit bodies 141 and two elastic side plates 142. The two snap-fit bodies 141 are spaced apart on opposite sides of the base 11 along the axis of rotation, and the elastic side plates 142 are spaced apart on opposite sides of the pressure cover 12 along the axis of rotation. Each snap-fit body 141 is snapped with a corresponding elastic side plate 142.
[0064] In some embodiments, please combine Figure 1 The snap-fit body 141 is a wedge-shaped block. The inclined surface of the wedge-shaped block forms the top wall of the wedge-shaped block. The wedge-shaped block is guided by the inclined surface and slides into the snap-fit hole 143 to realize the snap-fit between the wedge-shaped block and the snap-fit hole 143.
[0065] Thus, as the pressure cap 12 rotates to the closed state, the edge of the snap-fit hole 143 on the elastic side plate 142 contacts the inclined surface of the wedge block. The inclined surface of the wedge block decomposes the vertical closing force applied by the pressure cap 12 into a horizontal sliding component, forcing the elastic side plate 142 to elastically deform outward, causing the snap-fit hole 143 to slide along the inclined surface until it is fully engaged with the wedge block. During this process, the inclined surface continuously guides the alignment of the snap-fit hole 143 and the wedge block. When locking is complete, the bottom and side surfaces of the wedge block form surface contact with the inner wall of the snap-fit hole 143, preventing the snap-fit body 141 from moving, thereby forming a secure locking structure 14.
[0066] In some embodiments, please combine Figure 4 This application also provides an electronic device, which includes a fixing device 10; wherein, the first component 20 is a wireless network card, and the second component 30 is a signal cable. For example, the electronic device can be a laptop computer. Figure 4 This is a schematic diagram of the structure of the fixing device 10, the first component 20, the circuit board 40, and the fixing base 50 when the cover is in the closed state.
[0067] Thus, the wireless network card is placed in the bearing area 111 of the base 11, and the plug end of the signal cable is inserted into the wireless network card socket. When the cover 12 is rotated to the closed state, the slot 121 on the inner side of the cover 12 matches the shape of the signal cable plug, and the cover 12 presses against the signal cable, forcing the plug to maintain tight contact with the socket. When the cover 12 is in the closed state, the locking body 141 of the locking structure 14 is engaged in the locking hole 143 of the elastic side plate 142, forming a rigid fixation. The wireless network card and the signal cable are clamped and fixed by the base 11 and the cover 12, and the pressing force of the cover 12 acts directly on the plug-in part, eliminating the slight displacement caused by vibration or material deformation, thereby realizing a stable connection between the wireless network card and the signal cable to ensure the stability of electrical signal transmission.
[0068] Preferably, there are two signal cables and two sockets on the wireless network card, with each signal cable plug corresponding to its respective socket.
[0069] In some embodiments, please combine Figure 4 The electronic device also includes a circuit board 40, and the wireless network card is fixedly connected to the circuit board 40 through a fixing device 10; the upper surface of the circuit board 40 is provided with a base 11, the signal line passes through the base 11 in the vertical direction, and the first end of the signal line is inserted into the socket on the wireless network card, and the other end of the signal line is fixedly connected to the circuit board 40; wherein, the wireless network card is electrically connected to the circuit board 40 through the signal line.
[0070] Thus, the base 11 is directly fixed to the upper surface of the circuit board 40, so that the wireless network card and the circuit board 40 are spatially locked to prevent them from shifting laterally due to vibration; the first end of the signal line is plugged into the wireless network card socket through the plug, and the second end of the signal line is soldered to the pad of the circuit board 40 through the pin, so that the wireless network card and the circuit board 40 can achieve stable transmission of electrical signals.
[0071] It is understandable that circuit board 40 refers to the substrate that carries electronic components, specifically an FR-4 laminate material, used to provide the mounting base and electrical connection carrier for the wireless network card. Please refer to... Figure 2 The signal line passing through the base 11 in the vertical direction means that the signal line passes through the structure of the base 11 in a direction perpendicular to the plane of the circuit board 40. Specifically, this can be achieved by setting a through hole 113 in the base 11, and using the base 11 to form a physical limit on the signal line in the vertical direction.
[0072] Please combine Figure 2 Preferably, the top wall of the base 11 is also provided with a recess 112, so that when the plug is inserted into the socket, the part of the signal line near the plug is stored in the recess 112.
[0073] In some embodiments, please combine Figure 3 The second component 30 is a signal line, which includes a plug and pins. The plug forms the first end of the signal line and is inserted into the socket of the wireless network card. The pins form the second end of the signal line and are fixedly connected to the circuit board 40 by soldering.
[0074] In this way, the signal line is permanently fixed to the circuit board 40 through the pins, and is detachably connected to the wireless network card's socket through the plug, so as to facilitate the maintenance and replacement of the wireless network card.
[0075] It is understood that a pin refers to a metal conductor at the end of a signal line used to connect to the circuit board 40. Specifically, it can be implemented using a flat pad or a columnar solder foot 16, and a fixed connection is formed with the pad of the circuit board 40 by molten solder.
[0076] In some embodiments, please combine Figure 4 The base 11 and the circuit board 40 are fixed by welding to achieve rigid fixation between the base 11 and the circuit board 40, which effectively suppresses the relative displacement caused by mechanical vibration, avoids the wear and loosening problems of traditional detachable connection methods, and ensures the long-term stability of the internal structure of electronic devices.
[0077] Furthermore, each corner of the bottom wall of the base 11 is provided with solder feet 16, which are then soldered and fixed to the circuit board 40. For example, the solder feet 16 can be tin solder.
[0078] Please combine Figure 4In some embodiments, the end of the first component 20 facing away from the base 11 is connected to the circuit board 40 via a fixing seat 50. The fixing seat 50 is fixedly connected to the circuit board and detachably connected to the end of the first component 20 facing away from the base 11. The fixing seat 50 is used to support the end of the first component 20 facing away from the base 11.
[0079] 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.
