Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of cables, and more particularly relates to a buckle type anti-disengagement self-locking cable connector. BACKGROUND

[0002] A cable refers to a flexible conductive assembly with a conductive conductor as a core, covered by multiple layers of insulation, shielding, armoring, and sheathing, used for transmitting electric energy, electric signals, or realizing electromagnetic energy conversion. It is usually made of a conductor, an insulation layer, a filling layer, a shielding layer, a protection layer, and other functional units, twisted or extruded according to a specific process, and can realize electric energy transmission, signal transmission, or device interconnection in complex environments such as indoors, outdoors, underground, underwater, etc.

[0003] At present, a buckle type anti-disengagement self-locking cable connector has at least the following technical problems: Firstly, the butt joint locking structure design of the male head and the female head is unreasonable, lacks reliable self-locking anti-disengagement mechanism, and the traditional connector relies on single buckle or thread connection, with limited locking force. When subjected to external force impact, pulling or long-term vibration, the male head and the female head are easily separated, leading to transmission interruption, seriously affecting the normal operation of the equipment, and the operation of part of the locking structure is cumbersome, time-consuming and laborious in the unlocking process, reducing the construction and maintenance efficiency. Secondly, the clamping and fixing effect of the cable and the connector is not good, and the anti-displacement ability is insufficient. The existing clamping structure mostly adopts single mechanical clamping method, and the clamping force adjustment flexibility is poor, and lacks auxiliary fixing mechanism. When the cable is subjected to axial tension, relative displacement or even disengagement from the connector is easily caused. At the same time, the clamping surface is mostly smooth in design, and the friction is insufficient, further increasing the risk of falling off. Thirdly, the internal opening size of the connector is fixed, and the universality is poor. The cable diameters in different application scenarios are different, and the traditional connector cannot flexibly adjust the internal opening size. Special connectors need to be provided for cables of different diameters, which not only increases the use cost and inventory pressure, but also reduces the construction convenience. Fourthly, the safety protection performance needs to be improved. Part of the clamping parts and adjusting parts in contact with the cable are not made of insulating materials, which can easily cause short circuit accidents in humid or complex circuit environments. At the same time, core structural parts such as male head, female head, connecting barrel, etc. are mostly made of ordinary metal materials, and have not been effectively treated against rust. In humid and corrosive environments, rusting and deformation are easily caused, leading to a decrease in structural strength and a shortening of service life. SUMMARY

A mounting bracket is fixedly installed on one side of the annular plate, and a plurality of limiting grooves are provided on one side of the mounting bracket. An annular block is rotatably installed inside the annular plate, and a through groove is provided inside the annular block. A polygonal groove is provided on the periphery of the through groove, and a plurality of sliding plates are slidably installed inside the polygonal groove. A limiting rod is fixedly installed on one side of each of the plurality of sliding plates, and the plurality of limiting rods are slidably installed in the plurality of limiting grooves respectively.

[0009] Preferably, the adjustment assembly further includes a second arc-shaped groove, which is formed on the outer side wall of the annular plate.

Combined with the anti-slip texture on the inner side of the clamping plate, it can not only achieve initial stable clamping of the cable, but also further tighten the clamping force through the linkage of the spring rod and rotating plate when the cable is pulled by external force, preventing axial displacement of the cable and ensuring the firmness of the connection. The adjustment component rotates the ring block by turning the handle, which in turn moves the sliding plate in the polygonal groove synchronously.

The core components, such as the male and female connectors and the mounting plate, are made of alloy materials with an anti-rust coating, balancing structural strength and corrosion resistance to extend service life.

[0018] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0019] Please see Figures 1-8 This invention provides a snap-fit ​​anti-detachment self-locking cable connector, comprising: Male connector 1 and female connector 2. One end of male connector 1 has a insertion slot, and one end of female connector 2 is fixedly equipped with a insertion block. The insertion block and insertion slot are inserted into each other. Mounting discs 3 are fixedly installed at the ends of male connector 1 and female connector 2 that are furthest from each other. Cylindrical connecting cylinders 4 are fixedly installed on the furthest sides of the two mounting discs 3. Mounting rings 5 ​​are fixedly installed at the furthest ends of the two cylindrical connecting cylinders 4 that are furthest from each other. Cables 6 are movably connected to the two mounting rings 5. The opposite ends of the two cables 6 pass through the two cylindrical connecting cylinders 4 and extend into male connector 1 and female connector 2 respectively. Two sets of clamping assemblies are also included. The components are respectively installed inside two cylindrical connecting cylinders 4 and are used to clamp the two cables 6; two sets of adjustment components are respectively installed inside the male connector 1 and the female connector 2 and are used to adjust the size of the internal openings of the male connector 1 and the female connector 2. This connector achieves the stability and versatility of the cable 6 connection through the precise mating of the male connector 1 and the female connector 2, the anti-dislodgement fixation of the clamping components, and the opening adaptation of the adjustment components. The specific working mechanism is as follows: First, the plug block at one end of the female connector 2 is aligned with the plug slot of the male connector 1 and inserted to complete the initial positioning. At this time, the multiple retaining sleeves 27 on the outer wall of the female connector 2 are aligned with the male connector 1. When the insertion holes are aligned with the correct positions, the insertion rod 28 inside the sleeve 27 pops out under the elastic action of the return spring and inserts into the insertion hole to form a snap-lock, preventing the male connector 1 and female connector 2 from falling off during use and achieving self-locking during docking. To release the lock, press the insertion rod 28 to compress the return spring. After the cable 6 passes through the mounting ring 5 of the cylindrical connecting cylinder 4 and extends into the male connector 1 or female connector 2, the clamping assembly is fixed by both mechanical linkage and adsorption. In the initial state, the clamping plate 10 adheres to the outer wall of the cable 6 under the pull of the tension spring 24, while the telescopic air rod 25 drives the suction cup 26 to adsorb the surface of the cable 6. A preliminary clamping is formed. The spring rod 20 inside the mounting bracket 19 provides support for the rotating plate 21. The rotating plate 21 is connected to the sleeve 27 on the connecting plate 23 through the fixing plate 22. When the cable 6 is pulled by an external force, the connecting plate 23 drives the rotating plate 21 to rotate around the connection point. The elastic reaction force of the spring rod 20 is transmitted to the connecting plate 23 through the fixing plate 22, further pulling the clamping plate 10 to tighten and enhance the clamping force. The anti-slip texture on the inner side of the clamping plate 10 increases the friction with the cable 6. The suction force of the suction cup 26 prevents the axial displacement of the cable 6. The dual action ensures a firm connection and prevents it from falling off.The adjustment assembly can flexibly adjust the internal opening size of the male connector 1 and female connector 2 according to the cable specification 6 to improve versatility. Rotating the handle 16 on the outer wall of the male connector 1 or female connector 2 causes the handle 16 to slide along the first arc-shaped groove 7 and the second arc-shaped groove 14, driving the annular block 29 inside the annular plate 11 to rotate synchronously. Multiple evenly distributed sliding plates 17 are provided in the polygonal groove 15 of the annular block 29. When the annular block 29 rotates, the side wall of the polygonal groove 15 pushes the sliding plates 17 to slide along the limiting groove 13. The limiting rod 18 cooperates with the limiting groove 13 to restrict the offset of the sliding plates 17. When the sliding plates 17 synchronously move closer to or away from the center, the passage groove inside the annular block 29 can be adjusted. The opening size is adjustable to accommodate cables 6 of different diameters, and the sliding plate 17 made of insulating rubber provides insulation protection to prevent short circuits. In terms of overall functionality, the male connector 1, female connector 2, mounting plate 3, cylindrical connecting cylinder 4, and mounting ring 5 are all made of alloy materials with an anti-rust coating to ensure structural strength and corrosion resistance. The mounting plate 3 and cylindrical connecting cylinder 4 provide stable mounting support for the cable 6. The anti-slip, adsorption, and elastic clamping design of the clamping components, combined with the opening adaptation function of the adjusting components, enables the connector to achieve both anti-detachment self-locking of the cable 6 connection and good versatility and safety, making it suitable for stable cable 6 connections in various scenarios.

[0020] This invention provides a snap-fit ​​anti-detachment self-locking cable connector, which, in addition to the above-mentioned technical solution, also has the following technical features.

[0021] The clamping assembly includes a through groove 8, which is formed inside one of the cylindrical connecting cylinders 4. Two clamping plates 10 are slidably installed in the through groove 8. The two clamping plates 10 are symmetrically arranged, and their opposite sides are in contact with the outer wall of the cable 6. Two baffles 9 are symmetrically fixedly installed in the through groove 8. The outer walls of the two baffles 9 are horizontally aligned with the outer wall of the cylindrical connecting cylinder 4. A connecting plate 23 is provided on the opposite side of each of the two baffles 9. Both connecting plates 23 are slidably installed in the through groove 8. Two tension springs 24 are fixedly installed between one side of the cable 3 and the corresponding side of the clamping plate 10. A telescopic air rod 25 is provided between the two corresponding tension springs 24. The ends of the two telescopic air rods 25 that are far apart from each other are fixedly connected to one side of the connecting plate 23. The ends of the two telescopic air rods 25 that are close to each other pass through the corresponding clamping plate 10 and extend into the interior. Suction cups 26 are fixedly installed at the ends of the two telescopic air rods 25 that are close to each other. The two suction cups 26 are in contact with the outer wall of the cable 6.

[0022] In the initial state, the clamping plate 10 adheres to the outer wall of the cable 6 under the pull of the tension spring 24. At the same time, the telescopic air rod 25 drives the suction cup 26 to adsorb the surface of the cable 6 to form a preliminary clamp. The spring rod 20 in the mounting bracket 19 provides support for the rotating plate 21. The rotating plate 21 is connected to the sleeve 27 on the connecting plate 23 through the fixed plate 22. When the cable 6 is pulled by an external force, the connecting plate 23 drives the rotating plate 21 to rotate around the connection point. The elastic reaction force of the spring rod 20 is transmitted to the connecting plate 23 through the fixed plate 22, further pulling the clamping plate 10 to tighten and enhance the clamping force. In addition, the anti-slip texture on the inner side of the clamping plate 10 increases the friction with the cable 6. The adsorption force of the suction cup 26 prevents the axial displacement of the cable 6. The dual action ensures a firm connection and prevents it from falling off.

[0023] This invention provides a snap-fit ​​anti-detachment self-locking cable connector, which, in addition to the above-mentioned technical solution, also has the following technical features.

[0024] The clamping assembly also includes a mounting frame 19, which is fixedly mounted on the top surface of the cylindrical connecting cylinder 4. Two rotating plates 21 are movably mounted inside the mounting frame 19. The two rotating plates 21 are rotatably connected on opposite sides. A fixing plate 22 is fixedly mounted on the other side of each of the two rotating plates 21. Multiple sleeves 27 are fixedly mounted on the other side of each of the two connecting plates 23. One end of each sleeve 27 is fixedly connected to one side of the corresponding fixing plate 22. Two spring rods 20 are fixedly mounted inside the mounting frame 19. The top ends of the two spring rods 20 are fixedly connected to the bottom surfaces of the two rotating plates 21.

[0025] During the cable 6 connection operation, the mounting bracket 19 serves as a stable support structure for the entire clamping assembly. Its design, which is fixedly installed on the top surface of the cylindrical connecting cylinder 4, ensures the overall structural stability. Two rotating plates 21 are movably installed within the mounting bracket 19 and are rotatably connected to each other on opposite sides. This design allows the rotating plates 21 to rotate flexibly to adapt to situations where the cable 6 is subjected to external forces in different directions. Two fixed plates 22 are respectively fixedly installed on the other side of the two rotating plates 21, providing a foundation for subsequent connection with the connecting plate 23. Multiple clamping sleeves 27 are fixedly installed on the other side of the two connecting plates 23, with one end fixedly connected to the side of the corresponding fixed plate 22. This connection method creates a stable linkage between the connecting plate 23 and the rotating plate 21. At the same time, two spring rods 20 fixedly installed within the mounting bracket 19 have their top ends fixedly connected to the bottom surfaces of the two rotating plates 21, providing elastic support for the rotating plates 21. This allows the rotating plates 21 to rotate around the connection point when the cable 6 is subjected to external forces, and the elastic reaction force of the spring rods 20 further enhances the clamping force.

[0026] This invention provides a snap-fit ​​anti-detachment self-locking cable connector, which, in addition to the above-mentioned technical solution, also has the following technical features.

[0027] The adjustment assembly includes an annular plate 11, which is fixedly installed inside the male head 1. A mounting bracket 12 is fixedly installed on one side of the annular plate 11. Multiple limiting grooves 13 are provided on one side of the mounting bracket 12. An annular block 29 is rotatably installed inside the annular plate 11. A through groove is provided inside the annular block 29. A polygonal groove 15 is provided around the through groove. Multiple sliding plates 17 are slidably installed inside the polygonal groove 15. A limiting rod 18 is fixedly installed on one side of each of the multiple sliding plates 17. The multiple limiting rods 18 are slidably installed in the multiple limiting grooves 13 respectively.

[0028] The internal opening size of the male connector 1 and female connector 2 can be flexibly adjusted according to the cable 6 specification to improve versatility. By rotating the handle 16 on the outer wall of the male connector 1 or female connector 2, the handle 16 slides along the first arc groove 7 and the second arc groove 14, causing the annular block 29 in the annular plate 11 to rotate synchronously. The polygonal groove 15 of the annular block 29 is provided with multiple evenly distributed sliding plates 17. When the annular block 29 rotates, the side wall of the polygonal groove 15 pushes the sliding plate 17 to slide along the limiting groove 13. The limiting rod 18 cooperates with the limiting groove 13 to limit the offset of the sliding plate 17. When the sliding plate 17 moves closer to or away from the center, the opening size of the through groove in the annular block 29 can be adjusted to adapt to cables 6 of different diameters.

[0029] This invention provides a snap-fit ​​anti-detachment self-locking cable connector, which, in addition to the above-mentioned technical solution, also has the following technical features.

[0030] The adjustment assembly also includes a second arc-shaped groove 14, which is formed on the outer side wall of the annular plate 11. The outer side wall of the male head 1 is provided with a first arc-shaped groove 7, which is connected to the second arc-shaped groove 14. The same handle 16 is provided in the first arc-shaped groove 7 and the second arc-shaped groove 14. The bottom end of the handle 16 is fixedly connected to the outer side wall of the annular block 29. The outer side wall of the handle 16 is slidably connected to the inner side wall of the first arc-shaped groove 7 and the second arc-shaped groove 14, respectively.

[0031] In practical use, when it is necessary to adjust the size of the internal opening of the connector, the operator only needs to hold the handle 16. Since the bottom end of the handle 16 is fixedly connected to the outer wall of the annular block 29, and the outer wall of the handle 16 is slidably connected to the inner sidewall of the first arc groove 7 and the second arc groove 14 respectively, when the handle 16 is pushed to slide along the first arc groove 7 and the second arc groove 14, it can drive the annular block 29 to rotate synchronously in the annular plate 11. When the annular block 29 rotates, the sidewall of its polygonal groove 15 will push the sliding plate 17 to slide along the limiting groove 13. The cooperation between the limiting rod 18 and the limiting groove 13 can limit the offset of the sliding plate 17, thereby making the sliding plate 17 move closer to or away from the center synchronously, so as to adjust the opening size of the groove in the annular block 29 to adapt to cables 6 of different diameters.

[0032] This invention provides a snap-fit ​​anti-detachment self-locking cable connector, which, in addition to the above-mentioned technical solution, also has the following technical features.

[0033] Multiple sliding plates 17 are evenly distributed.

[0034] This uniformly distributed design allows the sliding plates 17 to maintain a stable motion state during adjustment, ensuring that the moving distance of each sliding plate 17 is consistent, thereby guaranteeing the accuracy and uniformity of adjusting the opening size of the groove within the annular block 29.

[0035] This invention provides a snap-fit ​​anti-detachment self-locking cable connector, which, in addition to the above-mentioned technical solution, also has the following technical features.

[0036] Multiple retaining sleeves 27 are fixedly installed on the outer side wall of the female head 2. Insertion holes are opened at the corresponding positions of the multiple retaining sleeves 27 on the outer side wall of the male head 1. The same insertion rod 28 is movably connected between the multiple retaining sleeves 27 and the corresponding insertion holes. The outer side wall of the multiple insertion rods 28 is provided with a return spring.

[0037] When connecting male connector 1 and female connector 2, male connector 1 is inserted into female connector 2. At this time, each retainer 27 will be inserted into the corresponding insertion hole on the outer wall of male connector 1. Then, the insertion rod 28 is inserted into the retainer 27 and the insertion hole in sequence. During the insertion process, the insertion rod 28 will compress the return spring, causing the return spring to undergo elastic deformation. When the insertion rod 28 is fully inserted, the return spring will apply a reverse force due to its own elasticity, which will firmly fix the insertion rod 28 between the retainer 27 and the insertion hole, thereby achieving a stable connection between male connector 1 and female connector 2 and preventing it from falling off during use. Moreover, this connection method is simple and convenient to operate, and can quickly realize the installation and removal of male connector 1 and female connector 2.

[0038] This invention provides a snap-fit ​​anti-detachment self-locking cable connector, which, in addition to the above-mentioned technical solution, also has the following technical features.

[0039] The multiple clamping plates 10 and the multiple sliding plates 17 are all made of insulating rubber.

[0040] This insulating rubber material has excellent insulation properties, which can effectively prevent current leakage during the connection process and ensure the safety of users.

[0041] This invention provides a snap-fit ​​anti-detachment self-locking cable connector, which, in addition to the above-mentioned technical solution, also has the following technical features.

[0042] The male connector 1, female connector 2, two mounting discs 3, two cylindrical connecting cylinders 4, and two mounting rings 5 ​​are all made of alloy material and have an anti-rust coating on their surfaces.

[0043] The alloy material has high strength and hardness, which ensures that components such as male connector 1 and female connector 2 are not easily deformed or damaged during long-term use, thus extending the service life of the entire connector. The anti-rust coating on the surface can effectively prevent the alloy material from rusting in harsh environments such as humidity, further improving the durability and stability of the components and ensuring that the connector can operate reliably in various complex working environments.

[0044] This invention provides a snap-fit ​​anti-detachment self-locking cable connector, which, in addition to the above-mentioned technical solution, also has the following technical features.

[0045] Anti-slip textures are provided on opposite sides of the multiple clamping plates 10.

[0046] These anti-slip patterns are distributed in a regular wave or stripe pattern. Their function is to increase the friction between the cable 6 and the surface of the cable 6 after the cable 6 is inserted into the connector, thereby effectively preventing the cable 6 from sliding or loosening inside the connector.

[0047] Working Principle: This connector achieves stability and versatility in cable 6 connection through precise mating of male head 1 and female head 2, anti-detachment fixing of the clamping component, and adaptation of the opening of the adjustment component. The specific working mechanism is as follows: First, the plug block at one end of female head 2 is aligned with the plug slot of male head 1 for initial positioning. At this time, multiple retaining sleeves 27 on the outer wall of female head 2 align with the corresponding insertion holes of male head 1. The insertion rod 28 inside the retaining sleeve 27 pops out under the elastic action of the return spring and inserts into the insertion hole to form a snap-lock, preventing male head 1 and female head 2 from falling off during use and achieving self-locking during mating. To release, pressing the insertion rod 28 compresses the return spring to release the lock. After cable 6 passes through the mounting ring 5 of the cylindrical connecting cylinder 4 and extends into the male head 1 or female head 2, the clamping component, through mechanical linkage, connects with... The suction effect provides dual fixation. In the initial state, the clamping plate 10 adheres to the outer wall of the cable 6 under the pull of the tension spring 24. At the same time, the telescopic air rod 25 drives the suction cup 26 to adhere to the surface of the cable 6 to form a preliminary clamp. The spring rod 20 in the mounting bracket 19 provides support for the rotating plate 21. The rotating plate 21 is connected to the sleeve 27 on the connecting plate 23 through the fixed plate 22. When the cable 6 is pulled by an external force, the connecting plate 23 drives the rotating plate 21 to rotate around the connection point. The elastic reaction force of the spring rod 20 is transmitted to the connecting plate 23 through the fixed plate 22, further pulling the clamping plate 10 to tighten and enhance the clamping force. In addition, the anti-slip texture on the inner side of the clamping plate 10 increases the friction with the cable 6. The suction force of the suction cup 26 prevents the axial displacement of the cable 6. The dual effect ensures a firm connection and prevents it from falling off. The adjustment assembly can flexibly adjust the internal opening size of the male connector 1 and female connector 2 according to the cable specification 6 to improve versatility. Rotating the handle 16 on the outer wall of the male connector 1 or female connector 2 causes the handle 16 to slide along the first arc-shaped groove 7 and the second arc-shaped groove 14, driving the annular block 29 inside the annular plate 11 to rotate synchronously. Multiple evenly distributed sliding plates 17 are provided in the polygonal groove 15 of the annular block 29. When the annular block 29 rotates, the side wall of the polygonal groove 15 pushes the sliding plates 17 to slide along the limiting groove 13. The limiting rod 18 cooperates with the limiting groove 13 to restrict the offset of the sliding plates 17. When the sliding plates 17 synchronously move closer to or away from the center, the passage groove inside the annular block 29 can be adjusted. The opening size is adapted to cables 6 of different diameters, and the sliding plate 17 made of insulating rubber can provide insulation protection to avoid short circuits.
