[0021] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0022] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which this application belongs.

[0023] Example 1

[0024] The embodiment of the present application provides a connection structure, such as Figure 1 As shown, it includes: a connecting part 1, which is used to be detachably connected to the device body 3 of the electronic device; a fixing part 2, which has a pair of limiting members 201 that are relatively arranged and have adjustable spacing, and the pair of limiting members 201 are used to clamp the wire connector 401 connected to the device body 3 to limit the displacement of the wire connector 401 relative to the device body 3.

[0025] The connecting part 1 is detachably connected to the device body 3 of the electronic device, so that the connecting part 1 can be separated or installed from the device body 3, which greatly facilitates daily maintenance, system upgrades or component replacement operations. The fixing part 2 is connected to the connecting part 1, and the wire connector 401 can be accurately clamped by a pair of limiters 201 in the fixing part 2, thereby effectively suppressing the displacement of the wire connector 401, and at the same time, it can also provide necessary support for the wire connector 401 to prevent loosening and falling off. Even if the device body 3 encounters vibration or external force impact, the continuous stability of the electrical connection can be ensured, and the risk of signal interruption and short circuit is significantly reduced. The spacing between the pair of limiters 201 is adjustable, so that the connection structure can adapt to wire connectors 401 of various specifications, improving its versatility and flexibility in different electronic equipment applications. The user can also adjust the clamping force of the limiter 201 on the wire connector 401 according to actual needs, which can ensure the stable connection of the wire connector 401 when necessary, and appropriately release the wire connector 401 when the external force is too large, thereby avoiding damage to the wire 4 and leakage problems caused by strong pulling, as well as accidental falling off and damage to the equipment and components, thereby protecting the overall safety and integrity of the equipment.

[0026] In some embodiments, one limiting member 201 can be moved closer to or farther away from another limiting member 201 , or a pair of limiting members 201 can be moved closer to or farther away from each other.

[0027] At least one of the limiters 201 remains fixed, while the other as a movable part can freely move closer to or farther from the fixed limiter 201, or both limiters 201 are designed to be in an active state, and the distance between them can be adjusted. This dynamic spacing adjustment capability ensures the perfect matching and stable clamping of wire connectors 401 of various sizes, and an appropriate fixing effect can be obtained regardless of the diameter. At the same time, through precise spacing control, not only the stability of the wire connector 401 in the face of mechanical vibration and accidental collision is enhanced, but also the requirements of fixation and release are balanced by finely controlling the clamping force. Even if an abnormal pulling force is encountered, the wire connector 401 can be relaxed in time, which not only protects the wire 4 from damage, but also prevents possible safety hazards such as equipment displacement and falling off.

[0028] Specifically, the stopper 201 can be installed in a fixing part 2 having a guide rail structure, and each stopper 201 is connected to the guide rail through a slider at the bottom. The user can manually push the stopper 201 to slide along the guide rail, so that the two stoppers 201 are moved closer to or farther from each other to accommodate wire connectors 401 of different diameters. In order to ensure smooth sliding and fixed position, a positioning hole or groove can be provided on the guide rail to cooperate with the positioning pin on the slider.

[0029] In some embodiments, the stopper 201 is an arc-shaped elastic structure adapted to the wire connector 401 , and a pair of the stoppers 201 can abut against the outer peripheral surface of the wire connector 401 .

[0030] The stopper 201 can be made of a material with good elasticity, such as silicone rubber, elastic plastic or other suitable elastic materials, which can ensure that sufficient resilience is maintained even after long-term use. Each stopper 201 is designed to be an arc that conforms to the contour of the wire connector 401, and the central recessed portion coincides with the outer peripheral shape of the wire connector 401. When a pair of stoppers 201 are closed, they can tightly wrap the wire connector 401, and use their own elastic force to generate a uniform and moderate clamping force, which can effectively reduce the displacement of the wire connector 401 when the device is vibrating or stressed. At the same time, due to its elastic characteristics, even if it encounters an abnormal pulling force, it can allow the wire connector 401 to relax in time, reducing the damage that may be caused to the wire connector 401 by hard compression.

[0031] In some embodiments, the fixing portion 2 includes a pair of first side walls 202 that are oppositely disposed, and at least one stopper 201 is movably connected to one of the first side walls 202 .

[0032] The fixing portion 2 has a pair of first side walls 202 arranged opposite to each other, which can surround the two sides of the wire connector 401, thereby forming a stable support frame. At least one stopper 201 can be flexibly connected to any first side wall 202 by an adjustment mechanism (such as a threaded knob or a combination of a slide groove and a slider), so that the spacing between the pair of stoppers 201 can be adjusted, thereby fixing the wire connector 401. The first side wall 202 has sufficient strength and rigidity to support the reaction force generated by the stopper 201 when clamping the wire connector 401.

[0033] In some embodiments, Figure 1 and Figure 2 As shown, the first side wall 202 is provided with a limiting hole, the axial direction of the limiting hole is perpendicular to the wire connector 401 , and the limiting member 201 can pass through the limiting hole and abut against the outer peripheral surface of the wire connector 401 .

[0034] The first side wall 202 is provided with a limiting hole, and the limiting hole maintains a vertical relationship with the wire connector 401 along the axial direction. At least one limiting member 201 is designed to be able to pass through these limiting holes and finally fit the outer peripheral surface of the wire connector 401 to achieve a stable fixation. The vertical alignment design of the limiting hole and the wire connector 401 ensures that the limiting member 201 can accurately align with the wire connector 401 and apply a uniform clamping force, thereby improving the stability and reliability of the connection.

[0035] The diameter of the limit hole is slightly larger than the diameter of the limit piece 201, ensuring that the limit piece 201 can be smoothly inserted and adjusted. The limit hole can be a threaded structure, forming a threaded connection with the rod-shaped limit piece 201 which also has threads on the outside. By rotating the limit piece 201, its extension length can be flexibly adjusted, so as to accurately control the distance between the two limit pieces 201. One end of the limit piece 201 can be designed with a contact surface that matches the outer shape of the wire connector 401, and the other end may have a handle or a knob, which is convenient for the user to operate the limit piece 201 to pass through the limit hole and adjust the position. The material of the limit piece 201 can be selected from materials with certain elasticity and wear resistance, such as nylon, engineering plastics or metal alloys, to ensure stable performance under long-term use. The user can place the wire connector 401 between a pair of first side walls 202, then pass the limiting member 201 through the corresponding limiting holes one by one, and manually rotate the handle or knob on the limiting member 201 to gradually approach the outer surface of the wire connector 401 until the ideal clamping force is reached.

[0036] In some embodiments, the fixing portion 2 may include an elastic structure, such as a spring, and the expansion and contraction direction of the elastic structure maintains a perpendicular relationship with the wire connector 401, and the stopper 201 is connected to the first side wall 202 through the elastic structure. Specifically, one end of the spring is fixed to the first side wall 202, and the other end is connected to the stopper 201. When installing, the user first places the wire connector 401 between the first side walls 202, and then presses the stopper 201 lightly to compress the spring, and the stopper 201 moves to the vicinity of the wire connector 401. After releasing, the restoring force of the spring makes the stopper 201 close to the outer periphery of the wire connector 401 to achieve a stable clamping. The spring can provide a dynamic clamping force for the stopper 201, and can automatically adjust according to the actual size of the wire connector 401, which not only avoids damage caused by over-tightening, but also prevents unstable connection caused by over-loosening, thereby improving the flexibility and adaptability of use.

[0037] In some embodiments, the fixing portion 2 further includes a second side wall 203 , a pair of first side walls 202 are connected by the second side wall 203 , the second side wall 203 is provided with a wire groove 204 , the wire groove 204 is located between the pair of first side walls 202 , and the wire groove 204 is arc-shaped.

[0038] A pair of first side walls 202 are connected to each other through the second side wall 203 to form a closed or semi-closed space, so that the fixing part 2 becomes a more solid unit as a whole and can withstand greater external forces. A wire groove 204 is provided on the second side wall 203, and the wire groove 204 is located between the two first side walls 202, providing space for the plugging of the wire connector 401. The wire groove 204 is designed in an arc shape, which can match the natural bending shape of the wire connector 401. This effectively alleviates the physical strain of the wire connector 401 in the bending area, and prevents the insulation layer from being damaged or the internal conductor from being damaged due to excessive bending.

[0039] In some embodiments, the connection structure further includes: a buffer portion, which is disposed on the side of the wire slot 204 facing the wire connector 401 , and is a flexible structure that can abut against the wire connector 401 when the wire connector 401 is clamped by a pair of limit members 201 .

[0040] The buffer part is connected to the second side wall 203, and can cover the side of the wire slot 204 facing the wire connector 401. When the wire connector 401 is fixed, the buffer part can directly contact it. The buffer part can be made of a flexible material, such as rubber, soft plastic or sponge-like material. These materials have good elasticity and can be deformed and restored to their original shape when subjected to pressure. They can provide a buffering effect when the wire connector 401 is bent, reduce the displacement or damage of the wire connector 401 caused by external force, and avoid the wire connector 401 from having a hard contact with the side wall of the wire slot 204 when bent, resulting in damage to the outer skin of the wire 4.

[0041] In some embodiments, the buffer portion may be provided on one side of a pair of stoppers 201 for clamping the wire connector 401. In the process of the stopper 201 clamping the wire connector 401, the buffer portion may first contact the wire connector 401, absorb and disperse the excess pressure that may be generated when the stopper 201 is closed, prevent direct transmission to the wire connector 401, and reduce the risk of physical damage. At the same time, the buffer portion can also absorb part of the energy of vibration or impact encountered during the operation of the equipment, protecting the wire connector 401 from vibration damage. Direct physical damage caused by excessive clamping or mechanical vibration during the operation of the equipment is avoided, and the service life of the wire 4 and the wire connector 401 is extended.

[0042] In some embodiments, Figure 1 As shown, the connecting portion 1 includes a third side wall 101 , and the third side wall 101 is provided with a first connecting hole 102 , and the first connecting hole 102 is used for bolt connection with the docking hole on the equipment body 3 .

[0043] The surface of the third side wall 101 is provided with a first connection hole 102, which can be a threaded hole for aligning with a preset docking hole on the device body 3. Specifically, a bolt or a similar fastener can be used to pass through the first connection hole 102 to connect with the docking hole on the electronic device. By fastening with a thread or fixing with a nut, the connection structure can be assembled or disassembled with the electronic device body 3.

[0044] In some embodiments, the third side wall 101 may be directly connected to the pair of first side walls 202. Specifically, the pair of first side walls 202 are distributed on both sides of the third side wall 101 and are respectively perpendicular to the third side wall 101. The third side wall 101 and the pair of first side walls 202 may be processed into a continuous, seamless integrated structure through a bending process, which facilitates processing while ensuring the stability and rigidity of the structure.

[0045] In some embodiments, the third side wall 101 can be indirectly connected to a pair of first side walls 202 through the second side wall 203. Specifically, one side edge of the third side wall 101 can be integrated with the second side wall 203 through a bending process, and the two remain vertical. A pair of first side walls 202 are respectively arranged on both sides of the second side wall 203, and are also connected to the second side wall 203 in a vertical manner using a bending process, together forming a stable three-dimensional frame structure. With the second side wall 203 as an intermediary, not only a stable connection between the third side wall 101 and the first side wall 202 is achieved, but also a stable frame structure is constructed, which improves the compression and torsion resistance of the overall structure.

[0046] In some embodiments, one side edge of the third side wall 101 is vertically connected to the second side wall 203, and the first side wall 202 is vertically connected to the edge of the third side wall 101 connected to the second side wall 203 on both sides. A frame structure is formed with the third side wall 101 as the center and vertically extending from the three adjacent sides thereof. This frame structure improves the rigidity and stability of the overall structure and effectively resists the impact and distortion of external forces.

[0047] In some embodiments, the connecting portion 1 further includes at least one fourth side wall 103 , a pair of first side walls 202 are connected to the fourth side wall 103 via the third side wall 101 , the third side wall 101 and the fourth side wall 103 meet the vertical condition, and the fourth side wall 103 is provided with a second connecting hole 104 .

[0048] The third side wall 101 can be used as a connecting bridge to firmly combine a pair of first side walls 202 with at least one fourth side wall 103 to form a solid and stable three-dimensional frame structure. Specifically, the third side wall 101 can be directly vertically connected to the first side wall 202, or indirectly connected through the second side wall 203, and the specific connection method is not limited. At least one fourth side wall 103 is connected to the third side wall 101, and the third side wall 101 and the fourth side wall 103 meet the vertical condition, so that the fourth side wall 103 can fit with the device body 3, ensuring the stability and reliability of the connection. The second connecting hole 104 is provided on the fourth side wall 103, which can provide an additional fixing option for the connecting part 1, allowing the user to select the most suitable connection point according to the equipment installation environment and requirements, increasing the flexibility and convenience of installation, and at the same time reducing the weight of the connecting structure.

[0049] In some embodiments, the fourth side wall 103 is arranged opposite to the second side wall 203 through the third side wall 101, that is, the fourth side wall 103 forms a U-shaped or Z-shaped stable frame through the third side wall 101 and the second side wall 203, which can cover at least part of the wire connector 401, so that the connecting structure can protect the wire connector 401 from environmental damage (such as dust and water) while providing support for the wire connector 401.

[0050] In some embodiments, there may be multiple fourth side walls 103, and multiple fourth side walls 103 may be evenly arranged around the third side wall 101, and may be connected to the third side wall 101 through a bending process. For example, if the third side wall 101 presents a rectangular structure, four fourth side walls 103 are configured, and each fourth side wall 103 is connected to one side of the third side wall 101. Each fourth side wall 103 is provided with a second connection hole 104, and multiple fourth side walls 103 can be seamlessly connected to electronic devices of various structures, sizes and installation positions, thereby improving the market adaptability of the product. Users can select the most convenient or most suitable one or more third side walls 101 for connection according to the actual layout of the device, which has high flexibility, is easy to install, and reduces the difficulty and time cost of installation. The number of fourth side walls 103 is not limited and can be set according to the actual layout of the device.

[0051] In some embodiments, the connection portion 1 can utilize a snap-on connection to achieve a convenient and stable detachable connection with the device body 3 .

[0052] Specifically, an elastic buckle structure may be designed or connected to the third side wall 101. The buckle may be made of a material with a certain elasticity, such as spring steel or elastic plastic, and can be deformed and rebounded appropriately when subjected to force, thereby achieving reliable buckling and release functions. The buckle may be designed to be a structure that is compatible with the slot or protrusion structure on the device body 3, ensuring a tight and stable connection between the connecting part 1 and the device body 3. The elastic buckle can provide sufficient clamping force in the locked state to ensure a tight connection between the connecting part 1 and the device body 3, and is not easy to loosen even under vibration or slight impact conditions. At the same time, it allows users to easily complete installation or disassembly without the help of any tools, greatly improving the convenience of operation.

[0053] The connection structure provided in the embodiment of the present application is suitable for ensuring convenient plug-in and unplugging operation and stable electrical performance between the wire connector 401 and the device body 3, and is widely applicable to a variety of mainstream electronic devices, including but not limited to: desktop computers, laptops, televisions, etc.

[0054] Example 2

[0055] An embodiment of the present application provides an electronic device, such as Figure 3 As shown, it includes a device body 3, which is provided with an interface; a wire 4, which has a wire connector 401 adapted to the interface, and the wire connector 401 is detachably connected to the interface; a connecting structure, which includes a connecting part 1, and the connecting part 1 is used to be detachably connected to the device body 3; a fixing part 2, which has a pair of limiting members 201 that are oppositely arranged and have an adjustable spacing, and the pair of limiting members 201 are used to clamp the wire connector 401 to limit the displacement of the wire connector 401 relative to the device body 3.

[0056] The device body 3 is provided with standardized or proprietary interfaces, such as USB-C, HDMI, etc. These interfaces are provided with locking mechanisms to facilitate the insertion and removal of the wire connector 401, while ensuring stable electrical performance. The wire 4 has a wire connector 401, and the wire connector 401 part can be designed according to the interface type of the device body 3, which can not only match the physical structure, but also consider the compatibility of electrical parameters to ensure efficient and lossless data transmission or power supply. The connecting part 1 adopts a detachable design, such as being connected to the device body 3 by a buckle, a screw or a quick-insert and quick-release connector to achieve a simple connection with the device body 3. The fixing part 2 is arranged around the wire connector 401, and a pair of limiters 201 can be adjusted according to the diameter of the wire connector 401. The spacing of the limiters 201 can be changed by rotating the adjusting screw, the slider or other mechanical mechanism to ensure tightening without excessive pressure on the wire connector 401.

[0057] Through the design of adjustable limiter 201, no matter how the size of wire connector 401 changes, it can be stably and securely fixed, effectively preventing loosening due to vibration or external force. At the same time, reasonable limit force design avoids physical damage to wire connector 401. At the same time, it can be released appropriately in extreme cases (such as excessive pulling), protecting wire 4 and equipment from damage and improving safety of use.

[0058] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application.
