Description

Technical Field

[0001] This utility model relates to the field of lead wire device technology, and in particular to a high-fault-tolerant claw-shaped connector for lead wire devices based on in-tube docking. Background Technology

[0002] The high-tolerance claw connector is a core connection component of the lead wire device designed specifically for in-pipe docking scenarios. It can achieve fast and accurate connection of the lead wire even when the internal space of the pipe is limited and there are deviations in the docking. It is mainly used for pipeline wiring in the power, communication and other fields.

[0003] When existing cable-leading devices move cables inside pipes, the devices experience high friction, making operation laborious and unable to counteract rotational forces, leading to cable entanglement and making cable lead-leading operations inconvenient.

[0004] An existing patent (publication number: CN218040474U) discloses a cable lead device for power installation. Through a rotating friction structure, when the device moves the cable, a connecting collar is installed on the outer side of a metal universal tube. This connecting collar fixes a ball bearing mounting ring, allowing multiple friction balls to be installed inside the ball bearing mounting ring. Therefore, when the device moves, the friction balls contact the cable installation conduit, and the rotation of the friction balls reduces the frictional resistance generated during the device's movement. Furthermore, the rotation of the friction balls also counteracts the rotational force, preventing cable entanglement and facilitating cable lead-out operations.

[0005] Existing patents offer solutions to the above problems, but their wiring performance is poor. In actual use, the lack of a wiring structure makes the connection between the cable and the lead-in device neither stable nor convenient. It cannot withstand the pulling force and vibration during the traction process, and the cable is prone to falling off, affecting subsequent wiring and reducing the practicality of the device.

[0006] To address this, a high-fault-tolerant claw-shaped connector for lead wires based on in-tube mating is proposed. Utility Model Content

This can solve the problems of poor wire threading effect of existing lead wire devices. In actual use, due to the lack of a wiring structure, the connection between the cable and the lead wire device is neither stable nor convenient. It cannot withstand the tension and vibration during the pulling process, and the cable is prone to falling off, which affects subsequent wire threading and reduces the practicality of the device.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a high-tolerance claw-shaped connector for a lead wire based on in-tube docking, comprising a steel wire, a movable component fixedly connected to the front side of the steel wire, and a connector assembly fixedly connected to the other end of the movable component, the connector assembly comprising a connecting round block, a movable round block movably connected to the front side of the connecting round block, and L-shaped clamps rotatably connected to the four corners of the surface of the connecting round block near the movable round block, a magnetic block fixedly connected to the side of the movable round block near the connecting round block, and an annular locking block fixedly connected to the surface of the movable round block, trapezoidal locking blocks fixedly connected to the side of the four L-shaped clamps near the movable round block, and the trapezoidal locking blocks engaging with the annular locking blocks, and winding springs fixedly connected to both ends of the L-shaped clamps, with the other end of the winding springs fixedly connected to the connecting round block.

[0009] Preferably, the moving component includes a metal universal tube, with fixed circular blocks fixedly connected to both ends of the metal universal tube, and the two fixed circular blocks are respectively fixedly connected to a connecting circular block and a steel wire. Moving blocks are movably connected to the four corners inside the fixed circular blocks. A return spring is fixedly connected to the side of the moving block closer to the fixed circular block, and a ball bearing is movably connected to the side of the moving block away from the return spring.

[0010] Preferably, each of the four corners of the fixed circular block is provided with a moving groove for use with the moving block, and the side of the return spring away from the moving block is fixedly connected to the inner wall of the moving groove.

[0011] Preferably, the movable block has a rotating groove on the side away from the return spring that is used to cooperate with the ball, and the surface of the ball is in contact with the inner wall of the rotating groove.

[0012] Preferably, the four corners of the connecting block surface near the moving block are provided with connecting grooves for use with L-shaped clamps.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. By setting up a moving component, this application can utilize the flexible bending characteristics of the metal universal tube to adapt to complex turning paths inside the pipe. At the same time, by using ball bearings to convert sliding friction into rolling friction, the moving resistance inside the pipe is greatly reduced.

After docking, the winding spring rebounds and drives the L-shaped clamping plate and the trapezoidal locking block to reset, so that the trapezoidal locking block and the annular locking block are locked together, forming a double locking structure of magnetic attraction and locking, ensuring fast and firm docking, and improving the convenience of using the device.

[0027] 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.

[0028] Please see Figure 1-5 The present invention provides the following technical solution:

[0029] A high-tolerance claw-shaped connector for a lead wire based on in-tube docking includes a steel wire 1. A movable component 2 is fixedly connected to the front side of the steel wire 1, and a connector component 3 is fixedly connected to the other end of the movable component 2. The connector component 3 includes a connecting block 301. A movable block 302 is movably connected to the front side of the connecting block 301. L-shaped clamps 303 are rotatably connected to the four corners of the surface of the connecting block 301 near the movable block 302. A magnetic block 304 is fixedly connected to the side of the movable block 302 near the connecting block 301. An annular locking block 305 is fixedly connected to the surface of the movable block 302. Trapezoidal locking blocks 306 are fixedly connected to the four L-shaped clamps 303 near the side of the movable block 302, and the trapezoidal locking blocks 306 are engaged with the annular locking blocks 305. A winding spring 307 is fixedly connected to both ends of the L-shaped clamps 303, and the other end of the winding spring 307 is fixedly connected to the connecting block 301.

[0030] In this embodiment: the use of the movable circular block 302 and the bolt 9 provides positioning and installation space for the wire harness. After the wire harness is connected to the movable circular block 302, rotating the bolt 9 can complete the compression and positioning of the wire harness. When the connecting circular block 301 approaches the movable circular block 302, the magnetic force of the magnetic block 304 can pull the movable circular block 302 toward the connecting circular block 301. During the docking process, the inclined surfaces of the annular locking block 305 and the trapezoidal locking block 306 can drive the L-shaped clamping plate 303 to rotate and stretch the winding spring 307, thereby unfolding the L-shaped clamping plate 303. After docking, the winding spring 307 rebounds, driving the L-shaped clamping plate 303 to rotate. The trapezoidal locking block 306 is reset, causing it to engage and lock with the annular locking block 305. The two work together to achieve double locking, which improves the stability of the device. Then, the ball bearing 205 and the connecting block work together to make the ball bearing 205 rotate smoothly within the connecting block, which can convert sliding friction into rolling friction, significantly reducing the resistance of the wire harness to movement within the tube. When subjected to external force, the return spring 204 deforms to effectively buffer the impact from the outside, ensuring smooth movement of the wire harness. At the same time, the flexible bending characteristics of the metal universal tube 201 allow the wire harness to turn smoothly within the tube, which can adapt to complex turning paths within the tube and improve the wire harness threading efficiency.

[0031] Specifically, such as Figure 4 As shown, the movable component 2 includes a metal universal tube 201. Both ends of the metal universal tube 201 are fixedly connected to fixed round blocks 202. The two fixed round blocks 202 are respectively fixedly connected to the connecting round block 301 and the steel wire 1. Movable blocks 203 are movably connected to the four corners inside the fixed round blocks 202. A return spring 204 is fixedly connected to the side of the movable block 203 close to the fixed round block 202, and a ball bearing 205 is movably connected to the side of the movable block 203 away from the return spring 204.

[0032] Specifically, such as Figure 4 As shown, each of the four corners of the fixed circular block 202 is provided with a moving groove 4 for use with the moving block 203, and the side of the return spring 204 away from the moving block 203 is fixedly connected to the inner wall of the moving groove 4.

[0033] Specifically, such as Figure 4 As shown, the moving block 203 has a rotating groove 5 on the side away from the return spring 204, which is used to cooperate with the ball 205, and the surface of the ball 205 is in contact with the inner wall of the rotating groove 5.

[0034] In this embodiment: by using the ball bearing 205 in conjunction with the rotating groove 5, the ball bearing 205 rotates inside the rotating groove 5, which can convert sliding friction into rolling friction, thus greatly reducing the moving resistance inside the tube. At the same time, by using the moving block 203 in conjunction with the moving groove 4, when subjected to external force, the moving block 203 moves smoothly under the restriction of the moving groove 4 and compresses the return spring 204. The return spring 204 rebounds and drives the moving block 203 and the ball bearing 205 to return to their original positions, which can effectively buffer external impacts, ensure smooth movement of the wire harness, and improve the ease of use of the moving component 2.

[0035] Specifically, such as Figure 5 As shown, the four corners of the connecting block 301 near the moving block 302 are provided with connecting grooves 6 for use with the L-shaped clamp 303. The rotating end of the L-shaped clamp 303 is located inside the connecting groove 6, and the side of the coiling spring 307 away from the L-shaped clamp 303 is fixedly connected to the inner wall of the connecting groove 6.

[0036] Specifically, such as Figure 5 As shown, the connecting block 301 has a slot 7 on the side near the moving block 302 that is used to cooperate with the magnetic block 304, and the surface of the magnetic block 304 is in contact with the inner wall of the slot 7.

[0037] Specifically, such as Figure 5 As shown, a wire-threading groove 8 is provided on the side of the movable circular block 302 away from the magnetic block 304, and the surface of the wire bundle is in contact with the inner wall of the wire-threading groove 8.

[0038] Specifically, such as Figure 2 , Figure 5 As shown, the front side of the top of the movable circular block 302 is threaded with a bolt 9, and the port of the bolt 9 extends into the interior of the wire groove 8.

[0039] In this embodiment: the wire-passing groove 8 provides installation and positioning space for the wire harness, allowing the movable circular block 302 to be tightly connected to the wire harness. Simultaneously, by rotating the bolt 9, it extends into the wire-passing groove 8 and compresses and positions the wire harness, achieving stable fixation of the specific wire harness. This effectively resists external impacts to prevent detachment, ensuring the normal operation of the wire-passing process and improving the ease of use of the connector assembly 3. Then, through the cooperation of the magnetic block 304 and the slot 7, the magnetic block 304 can be precisely embedded into the slot 7 of the connecting circular block 301, utilizing its... Magnetic force completes the adsorption and fixation, achieving precise docking between the moving circular block 302 and the connecting circular block 301. During the docking process, with the help of the inclined surfaces of the annular locking block 305 and the trapezoidal locking block 306, the L-shaped clamping plate 303 is driven to rotate smoothly along the connecting groove 6 and stretch the coiling spring 307, completing the unfolding of the L-shaped clamping plate 303. After docking is completed, the coiling spring 307 rebounds, causing the L-shaped clamping plate 303 and the trapezoidal locking block 306 to reset, so that the trapezoidal locking block 306 and the annular locking block 305 engage and lock. The two work together to complete double locking, improving the stability of the device.

[0040] Specifically, such as Figure 1 , Figure 2 , Figure 3 As shown, a handle 10 is fixedly connected to the side of the steel wire 1 away from the moving component 2, and the surface of the handle 10 is provided with anti-slip texture.

[0041] Specifically, such as Figure 1 , Figure 2 , Figure 3 As shown, the surface of the steel wire 1 is covered with a silicone protective film, and the surface of the silicone protective film is provided with anti-slip texture.

[0042] In this embodiment: the handle 10 provides a stable gripping structure for the operator, making it easy to apply tension to the steel wire 1, thereby enabling the threading operation to be completed quickly. At the same time, the silicone protective film on the surface of the steel wire 1 not only protects the steel wire 1 from damage during friction inside the tube, but also improves the gripping comfort of the operator's hand, thus enhancing the ease of use of the device.

[0043] Working Principle: When threading wires into opposing pipes, the wire harness is first embedded into the threading groove 8 of the movable block 302. Simultaneously, the bolt 9 is rotated to extend it into the threading groove 8 and compress and position the wire harness. Then, the movable block 302 with the wire harness is inserted from one end of the pipe, and the connecting block 301 is placed into the other end. The pushing force of the steel wire 1 is manually adjusted. During movement, the ball bearing 205 rotates within the movable block 203, converting sliding friction into rolling friction, significantly reducing movement resistance within the pipe. Simultaneously, the flexible bending characteristics of the metal universal tube 201 allow the connecting block 301 to smoothly turn within the pipe, adapting to complex turning paths. When the connecting block 301 approaches the movable block 302, the magnetic force of the magnetic block 304 pulls the movable block 302 towards the connecting block 301. Even with slight spatial deviations or component misalignments within the pipe, the magnetic force compensates for docking errors, achieving high precision. For initial alignment with tolerance, during the docking process, the annular locking block 305 and the trapezoidal locking block 306 engage with each other, which can drive the L-shaped clamping plate 303 to rotate smoothly along the connecting groove 6 and stretch the winding spring 307, thus unfolding the L-shaped clamping plate 303. After the magnetic block 304 is embedded in the slot 7 of the connecting round block 301 to complete the magnetic attraction and fixation, the winding spring 307 rebounds and drives the L-shaped clamping plate 303 to reset, so that the trapezoidal locking block 306 and the annular locking block 305 are tightly engaged, forming a double locking structure to ensure a firm docking. After docking is completed, the operator can use the handle 10 to perform a stretching operation, which can drive the wire harness to move smoothly in the pipe to complete the threading. When encountering obstruction, the reset spring 204 deforms, which can effectively buffer the external impact and ensure the smooth movement of the wire harness. After the threading is completed, the bolt 9 is loosened to remove the wire harness, and then the L-shaped clamping plate 303 is pushed to release the lock, completing the separation of the moving round block 302 and the connecting round block 301, which facilitates the subsequent threading operation.

[0044] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
