Abstract
Description
Technical Field
[0001] This invention belongs to the field of electrical construction technology, specifically referring to a cable installation and docking auxiliary device. Background Technology
[0002] Small-gauge cables are widely used in electrical equipment installation, instrument wiring, and on-site maintenance. Currently, the main method for splicing these cables is manual twisting: the operator twists the stripped copper cores of the two cables together, tightens them with pliers, and finally wraps electrical tape around them for insulation. This traditional method has the following drawbacks: First, it is difficult to control the number of turns and the tightness of the copper core winding in manual twisting. This often results in areas that are too loose, leading to increased contact resistance, or too tight, damaging the copper core and causing the joint to overheat or even burn out. Second, the twisted copper cores have an irregular shape, which can easily cause deformation when wrapping the tape. The first problem is that the copper core is prone to air gaps or sharp corners, which reduces insulation reliability and the tape is easy to loosen under vibration. The second problem is that the entire operation relies on operating experience, resulting in poor quality consistency and low efficiency. This is especially true when working at height or in confined spaces, where errors are more likely to occur. Although some existing auxiliary crimping tools (such as manual crimping pliers) can achieve mechanical crimping of the copper core, the copper core is greatly deformed after crimping, which easily leads to stress concentration. Furthermore, it still requires separate insulation wrapping. There is a lack of auxiliary devices that integrate copper core docking, shaping, and temporary insulation fixation, which cannot meet the needs of fast, reliable, and standardized docking on site. Summary of the Invention
[0003] In order to overcome the shortcomings of the prior art, the present invention provides a cable installation and docking auxiliary device, which effectively solves the above problems.
[0004] The technical solution adopted by the present invention is as follows: The present invention provides a cable installation docking auxiliary device, including a clamping plate, a hinge frame, an insulating tape and a gathering mechanism. The hinge frame is hinged to one end of the clamping plate. The clamping plate includes two symmetrical and hinged plates. The gathering mechanism is slidably disposed inside the plates. One of the plates has a storage roller at its end. The insulating tape is wound around the storage roller.
[0005] Furthermore, the two plates have pre-reserved grooves on their opposite sides. The gathering mechanism is slidably disposed inside the pre-reserved grooves. One of the plates has symmetrical bosses on its side away from the hinge axis. The storage roller is rotatably disposed between the bosses. An elastic reset element is provided between the bosses and the storage roller. When the storage roller is rotated, it can rotate back to its original position after the external force is removed. A sliding groove is provided on the inner wall of the pre-reserved groove. A positioning groove is provided on the top wall of the plate. The positioning groove fits with the insulating tape. A clamping rod is provided at the end of the plate without the storage roller away from the hinge axis. The clamping rod is elastic and pulls the insulating tape out of the storage roller, lays it inside the positioning groove, and pulls it toward the clamping rod. The clamping rod can fix the insulating tape by clamping it. Cable hooks are symmetrically provided on both sides of the clamping plate. The cable hooks are located on the side of the hinge axis of the plate. The cable hooks are used to fix the cable. A buffer pad is provided on the top wall of one of the plates. The buffer pad limits the minimum distance after the plate is folded by hinge.
[0006] Furthermore, the gathering mechanism includes a slider one, which is slidably disposed in a reserved groove. The top of the slider one is provided with an arc-shaped platform. A sliding groove three is opened on one side wall of the slider. The sliding groove three is arranged longitudinally. A slider two is slidably disposed in the sliding groove three. The end of the slider two is slidably disposed in the sliding groove one. The arc surface of the arc-shaped platform faces the hinge axis of the plate. A hot melt module and a magnetic block are provided at the top of the arc-shaped platform. The magnetic block is disposed on the side of the hot melt module away from the hinge axis of the plate.
[0007] Preferably, the bottom end of the slider is provided with a button, which is electrically connected to the hot melt module. After pressing the button, the hot melt module is powered on and starts heating. The reserved slot and the end of the slide are both open. After the plate is hinged and folded, the folding mechanism can be pulled out from the reserved slot for disassembly and charging. The slider is provided with a battery to power the hot melt module. A magnetic groove is provided on one side wall of the slider, and an electrode for charging is provided in the magnetic groove.
[0008] Furthermore, the hinge frame includes a bracket, a pressing wheel, and a second sliding groove. The bracket is hinged to the plate, the second sliding groove is symmetrically located at the end of the bracket, the pressing wheel is slidably located between the second sliding grooves, and the pressing wheel has a retaining pin at both ends. The retaining pin is slidably located in the second sliding groove. After stripping the insulation of the two cables to be connected, they are respectively fixed on the cable hooks so that the copper cores are stacked on each other. Through repeated pressing of the pressing wheel, the copper cores of the cables can be fully embedded and fused together.
[0009] The beneficial effects of this invention using the above structure are as follows: The cable installation docking auxiliary device provided by this solution, firstly, replaces the traditional manual winding method by combining the flat laying of the hinge plate with the rolling of rollers to achieve copper core fusion. The copper cores of the two cables are evenly flattened and interlocked under the repeated rolling of the rollers, achieving full fusion of the copper wires that make up the copper cores, significantly reducing contact resistance and improving pull-out resistance, avoiding the risk of localized overheating caused by uneven winding; secondly, when the plate is closed, the insulating tape is automatically wrapped around the copper core connection point. Simultaneously, folding and closing the plate causes the gathering mechanism to dock, forming a large arc surface and clamping the insulating tape from the outside, sliding towards the hinge axis for convergence. At the same time, the storage roller slightly reverses its direction after the plate is folded, thus... The folded part of the insulating tape is pulled towards the gathering mechanism. The bent part of the insulating tape and the spliced arc-shaped platform form two arc-shaped contact surfaces, which match each other to form a complete outline of approximately circle. This allows the insulating tape to fit tightly against and gather the spread copper core, eliminating air gaps and sharp corners and improving uniformity. Third, the heat-fusion strip set on the slider can be heated after the tape is gathered in place to heat-melt and bond the insulating tape, forming a temporary fixation at the copper core connection. This prevents relative displacement of the copper core or loosening of the insulating tape during subsequent operations, greatly reducing the difficulty of operation. A single person can complete a high-quality connection. Fourth, the entire device has a simple structure and intuitive operation. It does not require complex electrical control and is suitable for rapid on-site construction, effectively improving the reliability, consistency and work efficiency of small-specification cable connections.

[0015] like Figures 1-7 As shown, the present invention provides a cable installation docking auxiliary device, including a clamping plate 1, a hinge frame 2, an insulating tape 3, and a gathering mechanism 4. The hinge frame 2 is hinged to one end of the clamping plate 1. The clamping plate 1 includes two symmetrical and hinged plates 101.

One of the plates 101 has a storage roller 109 at its end, and the insulating tape 3 is wound around the storage roller 109.
[0016] A reserved groove 103 is provided on the opposite side of plate 101 and another plate 101. The gathering mechanism 4 is slidably disposed inside the reserved groove 103. One of the plates 101 has a boss 108 symmetrically provided on the side away from the hinge axis. The storage roller 109 is rotatably disposed between the bosses 108. An elastic reset element is provided between the bosses 108 and the storage roller 109. When the storage roller 109 is rotated, it can be rotated back to its original position after the external force is removed. A sliding groove 104 is provided on the inner wall of the reserved groove 103. A positioning groove 102 is provided on the top wall of the plate 101. The positioning groove 102 is attached to the insulating tape 3. A clamping rod 106 is provided at one end of the plate 101 of the storage roller 109 away from the hinge axis of the plate 101. The clamping rod 106 is elastic and pulls the insulating tape 3 out of the storage roller 109, lays it inside the positioning groove 102 and pulls it toward the clamping rod 106. The clamping rod 106 can fix the insulating tape 3 by clamping it. Wire hooks 105 are symmetrically provided on both sides of the clamping plate 1. The wire hooks 105 are located on the side of the hinge axis of the plate 101 and are used to fix the cable. A buffer pad 107 is provided on the top wall of one of the plates 101. The buffer pad 107 limits the minimum distance after the plate 101 is hinged and folded.
[0017] The gathering mechanism 4 includes a slider 401, which is slidably disposed in a reserved groove 103. The top of the slider 401 is provided with an arc-shaped platform 404. The side wall of the slider 401 is provided with a sliding groove 402, which is arranged longitudinally. A slider 403 is slidably disposed in the sliding groove 402. The end of the slider 403 is slidably disposed in the sliding groove 104. The arc surface of the arc-shaped platform 404 faces the hinge axis of the plate 101. The top of the arc-shaped platform 404 is provided with a hot melt module 405 and a magnetic block 406. The magnetic block 406 is disposed on the side of the hot melt module 405 away from the hinge axis of the plate 101.
[0018] A button 407 is provided at the bottom of slider 401. Button 407 is electrically connected to the hot melt module 405. After pressing button 407, the hot melt module 405 is powered on and starts heating. The reserved slot 103 and the end of the slide 104 are both open. After the plate 101 is hinged and folded, the folding mechanism 4 can be pulled out from the reserved slot 103 for disassembly and charging. A battery is provided inside slider 401 to power the hot melt module 405. A magnetic groove 408 is provided on the side wall of slider 401. An electrode 409 for charging is provided inside the magnetic groove 408.
[0019] The hinge frame 2 includes a bracket 201, a pressing wheel 203, and a second sliding groove 202. The bracket 201 is hinged on the plate 101. The second sliding groove 202 is symmetrically arranged at the end of the bracket 201. The pressing wheel 203 is slidably arranged between the second sliding grooves 202. The pressing wheel 203 has a retaining shaft 204 at both ends. The retaining shaft 204 is slidably arranged in the second sliding groove 202. After stripping the insulation of the two cables to be connected, they are fixed on the hanging buckle 105 respectively, so that the copper cores are stacked on each other. Through repeated pressing of the pressing wheel 203, the copper cores of the cables can be embedded into each other and fully fused together.
[0020] In practical use, firstly, the insulating tape 3 is pulled out from the storage roller 109 and placed on the positioning groove 102, while its end is clamped and fixed by the clamping rod 106. Then, the ends of the cables to be connected are stripped and installed on the hanging buckles 105 respectively, so that the exposed copper cores of the two cables are stacked. Then, the hinge frame 2 is flipped to the top of the clamping plate 1, and the operator presses and rolls the pressing wheel 203. The pressing wheel 203 repeatedly rolls and presses the copper cores, so that the copper wires that make up the copper cores of the two cables are interlocked. After the copper core is fully integrated, the hinge frame 2 is removed and the plate 101 is flipped to fold and close. The insulating tape 3 wraps the integrated copper core inside the insulating tape 3. Then, the operator presses the slider 401 with two fingers to the inside, so that the retracting mechanism 4 is engaged. The magnetic blocks 406 attract each other to position the retracting mechanism 4. At the same time, the operator presses the button 407 and pulls the retracting mechanism 4 towards the hinge axis of the plate 101. The retracting mechanism 4 folds from the outside of the insulating tape 3 towards the insulating tape 3. The insulation tape 3 is gathered in the direction of the crease. At the same time, after the plate 101 is folded, the storage roller 109 will tend to gather the insulation tape 3 against the pressure of the cable due to the closer distance between the clamping rod 106 and the storage roller 109. The folded part of the insulation tape 3 will be pulled towards the gathering mechanism 4. The bent part of the insulation tape 3 and the spliced arc platform 404 form two arc-shaped contact surfaces, which are squeezed against each other to form a complete outline of approximately circle. This makes the insulation tape 3 closely adhere to and gather the spread copper core, eliminating air gaps and sharp corners, and improving the uniformity and sealing of the insulation. At the same time, after the gathering is completed, the hot melt module 405 has reached the set temperature and heats the insulation tape 3 to make the insulation tape 3 fuse and stick, and initially fixes the cable joint, which is convenient for operators to perform subsequent operations such as wrapping insulating tape. When the gathering mechanism 4 needs to be charged, simply fold the plate 101 and pull the gathering mechanism 4 out along the reserved groove 103 to remove it. The gathering mechanism 4 can then be placed on the external charger.
