Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a threaded tightening type waterproof and dustproof connector. Background Technology

[0002] In practical applications, connectors often need to operate in harsh environments, such as humid and dusty environments;

[0003] Ordinary connectors have poor waterproof and dustproof performance. Moisture and dust can easily enter the connector, causing electrical connection failure, affecting the normal operation of equipment, and even causing safety accidents. Most existing waterproof and dustproof connectors use sealing rings or clips for sealing, which has unstable sealing effect. During long-term use, the sealing rings are prone to aging, and the clips are prone to loosening, resulting in a decline in waterproof and dustproof performance. Moreover, these connectors are relatively cumbersome to install and disassemble, which consumes time and labor costs.

[0004] Therefore, this utility model proposes a threaded tightening type waterproof and dustproof connector. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a threaded, tightening, waterproof, and dustproof connector.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a threaded tightening type waterproof and dustproof connector, including a connector assembly, the connector assembly being composed of a connecting sleeve, and further including:

[0007] Both sides of the connecting sleeve are provided with threaded sleeves, and a clamping sleeve is provided on one side of the connecting sleeve. There are two clamping sleeves in total, and the two clamping sleeves are symmetrical about the center of the connecting sleeve.

[0008] Furthermore, the threaded sleeve is provided with a compression sleeve, and the compression sleeve and the threaded sleeve are threadedly connected. The compression sleeve is provided with a rotating protrusion.

[0009] The beneficial effects of adopting the above-mentioned further solution are: the rotating protrusion facilitates the operator to apply force to rotate the extrusion sleeve, and through the threaded connection with the threaded sleeve, the extrusion sleeve can move axially to apply pressure to the sealing components such as the sealing ring, thereby further enhancing the sealing effect. The design of the rotating protrusion makes the operation more labor-saving and precise; the extrusion sleeve and the threaded sleeve cooperate to realize dynamic extrusion adjustment of the sealing components, adapting to the sealing requirements under different working conditions. Even if the sealing ring is slightly worn, it can maintain good sealing performance through adjustment, which greatly improves the long-term waterproof and dustproof performance and reliability of the connector.

[0010] Furthermore, the rotating protrusions are arranged in a ring, and the spacing between two adjacent rotating protrusions is equal. The diameter of the extrusion sleeve is adapted to the threaded sleeve, and the extrusion sleeve contacts the rotating protrusions.

[0011] The beneficial effects of adopting the above-mentioned further solution are: the annularly distributed rotating protrusions make the force more uniform when the operator rotates the extrusion sleeve; the screw drive drives the extrusion sleeve to move axially, accurately extruding the sealing component; the matching diameter ensures that the extrusion sleeve and the threaded sleeve fit tightly; there is no radial offset during rotation, ensuring that the sealing pressure is applied evenly.

[0012] Furthermore, a protective component is provided on the connecting sleeve between the two threaded sleeves. The protective component consists of a reinforcing collar and reinforcing ribs. Multiple reinforcing collars are provided, and the multiple reinforcing collars are connected by reinforcing ribs, which are distributed in a ring.

[0013] The beneficial effects of adopting the above-mentioned further solutions are as follows: the reinforcing collar and reinforcing ribs in the protective assembly form a mesh structure. When the connecting sleeve is subjected to external force, the reinforcing collar disperses the stress through the reinforcing ribs. The annularly distributed reinforcing ribs evenly bear the radial pressure, preventing the threaded sleeve from deforming due to local stress, ensuring the axis alignment when the threads are tightened, maintaining the extrusion accuracy of the sealing assembly, and enhancing the deformation resistance of the connecting sleeve with the annular reinforcing ribs. This prevents thread misalignment caused by external force and ensures the effectiveness of the sealing structure. The mesh protective structure improves the overall mechanical strength, extends the service life of the connector, and ensures the smoothness of thread transmission, preventing the waterproof and dustproof performance from being affected by structural deformation.

[0014] Furthermore, an mounting plate is provided between the two threaded sleeves, and the two mounting plates are respectively provided on both sides of the reinforcing rib.

[0015] The beneficial effects of adopting the above-mentioned further solution are as follows: The mounting plate is fixed on both sides of the reinforcing rib, forming a composite support structure with the reinforcing collar and the reinforcing rib. When the connecting sleeve is under stress, the mounting plate bears the axial load and transmits it to the reinforcing collar through the reinforcing rib, dispersing the stress on the threaded sleeve, ensuring the coaxiality of the two threaded sleeves, and ensuring that the sealing component is evenly compressed when tightened. The mounting plate and the reinforcing rib work together to enhance the structural rigidity and prevent sealing failure caused by the displacement of the threaded sleeve. The mounting plates on both sides form symmetrical support, improving the connector's resistance to bending, making it suitable for vibration or impact scenarios, while ensuring the thread engagement accuracy, extending the service life of the sealing component, and enhancing the stability of waterproof and dustproof performance.

[0016] Furthermore, the curved waterproof membrane is provided with snap-fit ​​sleeves, and the curved waterproof membrane is snapped together with the reinforcing ribs through the snap-fit ​​sleeves.

[0017] The beneficial effects of adopting the above-mentioned further solution are as follows: The arc-shaped waterproof membrane is snapped together with the reinforcing ribs through a snap-fit ​​sleeve to form a detachable protective structure. When the connector is intruded by moisture, the arc-shaped waterproof membrane blocks the gaps, and the snap-fit ​​sleeve's fastening design guides the moisture along the surface of the membrane, preventing it from seeping into the threaded sleeve connection. At the same time, the snap-fit ​​structure can adaptively adjust the sealing angle according to the deformation of the reinforcing ribs. The snap-fit ​​arc-shaped waterproof membrane enhances local waterproofing capabilities and allows for quick disassembly and maintenance. The flow-guiding design prevents moisture accumulation and, together with the reinforcing rib structure, improves anti-permeability performance. The adaptive snap-fit ​​adapts to the micro-deformation of the structure under different working conditions, extends the service life of the waterproof components, and enhances the dynamic sealing performance of dustproof and waterproof.

[0018] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0019] In this invention, symmetrical clamping sleeves engage with connecting sleeves via threads. During rotation, they move axially to compress the cable, and simultaneous clamping on both sides creates symmetrical constraint forces, preventing eccentric stress on the cable. Simultaneously, the conical design of the clamping sleeves forces the sealing ring to expand radially, filling the gap between the cable and the sleeve, achieving both mechanical fixation and sealing. The symmetrical clamping structure ensures uniform cable stress, preventing loosening due to pulling. The conical compression ring enhances sealing reliability and adapts to cables of different diameters. Bidirectional synchronous clamping improves installation efficiency, and the symmetrical design balances axial force, reducing connector deformation caused by cable stress and enhancing long-term waterproof and dustproof performance.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] like Figure 1-5 As shown, this utility model provides a technical solution: a threaded tightening type waterproof and dustproof connector, including a connector assembly 1, which is composed of a connecting sleeve 11, and further including:

[0030] Both sides of the connecting sleeve 11 are provided with threaded sleeves 13. A clamping sleeve 131 is provided on one side of the threaded sleeve 13 on the connecting sleeve 11. There are two clamping sleeves 131 in total, and the two clamping sleeves 131 are symmetrical about the center of the connecting sleeve 11. The symmetrical clamping sleeves 131 are engaged with the connecting sleeve 11 through threads. When rotated, they move axially to squeeze the cable. The simultaneous clamping on both sides forms a symmetrical constraint force, which avoids the cable being subjected to eccentric force. At the same time, the conical design of the clamping sleeve 131 forces the sealing ring to expand radially, filling the gap between the cable and the sleeve, and achieving the dual function of mechanical fixation and sealing. The symmetrical clamping structure ensures that the cable is subjected to uniform force and prevents the connection from loosening due to pulling. The conical extrusion ring enhances the sealing reliability and is compatible with cables of different diameters. The bidirectional synchronous clamping improves the installation efficiency, and the symmetrical design balances the axial force, reduces the deformation of the connector caused by the cable force, and enhances the long-term waterproof and dustproof performance.

[0031] A compression sleeve 12 is provided on the threaded sleeve 13, and the compression sleeve 12 is threadedly connected to the threaded sleeve 13. A rotating protrusion 121 is provided on the compression sleeve 12, which allows the operator to apply force to rotate the compression sleeve 12. Through the threaded connection with the threaded sleeve 13, the compression sleeve 12 moves axially, applying pressure to sealing components such as the sealing ring, further enhancing the sealing effect. The design of the rotating protrusion 121 makes the operation more labor-saving and precise. The compression sleeve 12 and the threaded sleeve 13 cooperate to realize dynamic compression adjustment of the sealing components, adapting to the sealing requirements under different working conditions. Even if the sealing ring is slightly worn, it can maintain good sealing performance through adjustment, greatly improving the long-term waterproof and dustproof performance and reliability of the connector.

[0032] The rotating protrusions 121 are arranged in a ring, and the distance between two adjacent rotating protrusions 121 is equal. The diameter of the extrusion sleeve 12 is adapted to the threaded sleeve 13. The extrusion sleeve 12 contacts the rotating protrusions 121. The ring-shaped and equidistantly distributed rotating protrusions 121 make the force more uniform when the operator rotates the extrusion sleeve 12. The extrusion sleeve 12 is driven to move axially through the threaded drive to accurately extrude the sealing component. The matching diameter ensures that the extrusion sleeve 12 and the threaded sleeve 13 fit tightly. There is no radial offset during rotation, which ensures that the sealing pressure is applied evenly.

[0033] A protective component 2 is provided on the connecting sleeve 11 between two threaded sleeves 13. The protective component 2 consists of reinforcing rings 22 and reinforcing ribs 23. Multiple reinforcing rings 22 are provided, and the multiple reinforcing rings 22 are connected by reinforcing ribs 23. The reinforcing ribs 23 are distributed in a ring. The reinforcing rings 22 and reinforcing ribs 23 in the protective component 2 form a mesh structure. When the connecting sleeve 11 is subjected to external force, the reinforcing rings 22 disperse the stress through the reinforcing ribs 23. The ring-distributed reinforcing ribs 23 evenly bear the radial pressure, avoiding deformation of the threaded sleeves 13 due to local stress, ensuring the axis alignment when the threads are tightened, maintaining the compression accuracy of the sealing component, and enhancing the deformation resistance of the connecting sleeve 11. This prevents thread misalignment caused by external force and ensures the effectiveness of the sealing structure. The mesh protective structure improves the overall mechanical strength, extends the service life of the connector, and ensures the smoothness of thread transmission, avoiding the impact of structural deformation on waterproof and dustproof performance.

[0034] A mounting plate 21 is provided between the two threaded sleeves 13. The two mounting plates 21 are respectively set on both sides of the reinforcing rib 23. The mounting plates 21 are fixed to both sides of the reinforcing rib 23 and form a composite support structure with the reinforcing collar 22 and the reinforcing rib 23. When the connecting sleeve 11 is under force, the mounting plate 21 bears the axial load and transmits it to the reinforcing collar 22 through the reinforcing rib 23, dispersing the stress on the threaded sleeve 13, ensuring the coaxiality of the two threaded sleeves 13, and ensuring that the sealing assembly is evenly compressed when tightened. The mounting plate 21 and the reinforcing rib 23 work together to enhance the structural rigidity and prevent the sealing failure caused by the displacement of the threaded sleeve 13. The mounting plates 21 on both sides form symmetrical support, improve the connector's resistance to bending, and are suitable for vibration or impact scenarios. At the same time, they ensure the thread engagement accuracy, extend the service life of the sealing assembly, and enhance the stability of waterproof and dustproof performance.

[0035] The curved waterproof membrane 24 is equipped with a snap-fit ​​sleeve 241. The curved waterproof membrane 24 is snapped together with the reinforcing rib 23 through the snap-fit ​​sleeve 241. The snap-fit ​​sleeve 241 and the reinforcing rib 23 form a detachable protective structure. When the connector is invaded by water vapor, the curved waterproof membrane 24 blocks the gaps, and the snap-fit ​​design of the snap-fit ​​sleeve 241 guides the water vapor along the surface of the plate, preventing it from seeping into the connection of the threaded sleeve 13. At the same time, the snap-fit ​​structure can adaptively adjust the sealing angle according to the deformation of the reinforcing rib 23. The snap-fit ​​curved waterproof membrane 24 enhances the local waterproofing capability and can be quickly disassembled and maintained. The flow-guiding design prevents water vapor accumulation and, together with the structure of the reinforcing rib 23, improves the anti-permeability performance. The adaptive snap-fit ​​adapts to the micro-deformation of the structure under different working conditions, extends the service life of the waterproof component, and enhances the dynamic sealing performance of dustproof and waterproof.
