Description

Technical Field

[0001] This invention belongs to the field of cable connection technology, and particularly relates to a smart quick connector for low-altitude economic cables. Background Technology

[0002] With the rapid development of the low-altitude economy, new aircraft such as drones and electric vertical takeoff and landing (eVTOL) aircraft are placing higher demands on the reliability, safety, and maintenance efficiency of power transmission systems. Traditional cable connections often use bolts, welding, or ordinary plug-in connectors. These methods, when operating in complex environments, often suffer from problems such as cumbersome operation, long processing times, easy loosening, and poor contact. Especially in scenarios requiring frequent disassembly and assembly or rapid response, traditional connectors struggle to meet the demands for efficient, intelligent, and reliable connections, becoming a bottleneck restricting the operational efficiency and safe operation of low-altitude equipment.

[0003] Therefore, there is an urgent need for a new type of cable connection device capable of achieving fast, stable, and intelligent electrical connections. An ideal connector should not only have convenient installation and disassembly characteristics but also ensure reliable electrical connections under harsh operating conditions. In response to the above situation, there is an urgent need to develop an intelligent, quick-connect, safe, and reliable intelligent fast connector for low-altitude economic cables to overcome the shortcomings in current practical applications. Summary of the Invention

[0004] The purpose of this invention is to provide a smart quick connector for low-altitude economic cables, which aims to solve the problems mentioned in the background art.

[0005] This invention is implemented as follows: a smart quick connector for low-altitude economic cables, including a central connecting post, and further comprising:

[0006] Two core-passing posts are fixed at both ends of the middle connecting post. The two core-passing posts are circumferentially distributed with multiple core-passing channels for the cable core of the cable body to pass through, and the core-passing channels on the two core-passing posts are evenly staggered.

[0007] Two inner sleeves are rotatably mounted on the intermediate connecting column. Multiple connecting push plates are fixedly distributed circumferentially on the outer sides of the two inner sleeves to correspondingly separate the cable cores passing through the two core columns. An outer sleeve is fixed on the outer side of the connecting push plate.

[0008] The transmission assembly has a cover fixed on the outer side between the two core columns. The cover is equipped with a transmission assembly for driving the two outer sleeves to rotate in opposite directions. The cable cores are driven to move in opposite directions by the connecting push plate on the inner side of the two outer sleeves, so that the cable cores of the two cable bodies are correspondingly abutted and electrically connected.

[0009] A collar is also fitted on the cable body, and an end fixing cylinder is rotatably installed on the collar. The end of the end fixing cylinder away from the collar is threadedly connected to the end of the through-core post.

[0010] In a further technical solution, the number of connecting push plates fixed on the inner sleeve is the same as the number of core-piercing channels opened on the core-piercing column.

[0011] In a further technical solution, the ends of the two outer sleeves that are far apart are also rotatably connected to the core post.

[0012] In a further technical solution, an elastic anti-slip sleeve is fixed on the inner side of the collar, and an annular groove is provided on the outer side of the collar, with the end of the end fixing cylinder rotatably connected to the annular groove.

[0013] A further technical solution includes an adjustment knob, a worm shaft, a worm wheel shaft, a worm, a bevel gear ring, a bevel gear, and a worm wheel. Bevel gear rings are fixedly fixed to the outer sides of the two outer sleeves. A worm wheel shaft is rotatably mounted on the inner wall of the casing. A worm wheel is fixed on the worm wheel shaft. A bevel gear, meshing with both bevel gear rings, is also fixed to the end of the worm wheel shaft. A worm shaft is also rotatably mounted on the casing. A worm, meshing with the worm wheel, is fixed on the worm shaft. An adjustment knob is fixed to one end of the worm shaft.

[0014] In a further technical solution, the worm shaft and the worm wheel shaft are arranged vertically, and the worm shaft is connected to the damping rotatable connection of the cover.

[0015] A further technical solution includes an auxiliary fixing assembly for securing the cable core threaded on the through-core post. The auxiliary fixing assembly includes a locking cylinder, locking pins, a locking plate, side extension blocks, and springs. Each through-core post has circumferentially distributed sliding openings corresponding to the through-core channels. A locking plate is slidably mounted on each sliding opening. Side cavities are formed on both sides of the sliding openings. Side extension blocks extending into the side cavities are fixed at both ends of the locking plate. Springs are also provided in the side cavities for elastic support of the side extension blocks. A locking cylinder is rotatably mounted on the through-core post. Multiple locking pins are circumferentially fixed on the inner side of the locking cylinder. When the locking pins are not in contact with the locking plate, the locking plate separates from the through-core channels under the elastic force of the springs. When the locking cylinder is rotated, the locking pins push the locking plate to move, thereby causing the locking plate to extend into the through-core channels and secure the cable core.

[0016] A further technical solution is that the inner end of the locking plate is rounded; the locking pin adopts a 1 / 2 cylindrical structure, the outer end of the locking plate adopts a central arc-shaped concave structure, and when the locking pin is locked at the outer end of the locking plate, the locking plate extends into the core-penetrating channel and fixes the cable core.

[0017] In a further technical solution, both ends of the locking cylinder are also connected to the through-core column for damping rotation.

[0018] The present invention provides a smart quick connector for low-altitude economic cables, which has the following beneficial effects:

[0019] The through-hole channels of the through-hole posts facilitate the separate installation of cable cores. The staggered arrangement of the through-hole channels on the two through-hole posts prevents interference between the cable cores of the two main cable bodies during installation, improving convenience. The inner sleeve, outer sleeve, and connecting push plate design allow the connecting push plate to separate the cable cores installed on the two through-hole posts in pairs. A transmission component drives the two outer sleeves to rotate in opposite directions, and the connecting push plate inside the two outer sleeves drives the cable cores to move in opposite directions, thus ensuring that the cable cores of the two main cable bodies abut and are electrically connected. This connection method is intelligent, reliable, and quick. Furthermore, the combination of the collar and end fixing sleeve provides both protection and aesthetic appeal.

[0020] In summary, this invention achieves interference-free cable core installation and automatic alignment electrical connection through the staggered core-passing channel and connecting push plate design, while also possessing the advantages of intelligent and convenient operation and reliable connection.

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0031] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0032] like Figure 1-2 As shown in Figures 6-8, a smart quick connector for low-altitude economic cables is provided according to an embodiment of the present invention, including an intermediate connecting post 12, and further comprising:

[0033] Two core-passing posts 8 are fixed at both ends of the intermediate connecting post 12. Multiple core-passing channels 9 for the cable core 10 of the cable body 7 to pass through are distributed circumferentially on the two core-passing posts 8, and the core-passing channels 9 on the two core-passing posts 8 are evenly staggered.

[0034] Two inner sleeves 13 are rotatably mounted on the intermediate connecting column 12. Multiple connecting push plates 26 are fixedly distributed on the outer circumferential side of the two inner sleeves 13 to correspondingly separate the cable cores 10 passing through the two core columns 8. An outer sleeve 14 is fixed on the outer side of the connecting push plate 26.

[0035] The transmission assembly includes a cover 1 fixed on the outer side between the two core columns 8. The cover 1 is equipped with a transmission assembly for driving the two outer sleeves 14 to rotate in opposite directions. The connecting push plate 26 on the inner side of the two outer sleeves 14 drives the cable cores 10 to move in opposite directions, thereby causing the cable cores 10 of the two cable bodies 7 to abut and be electrically connected.

[0036] A collar 6 is also fitted on the cable body 7. An end fixing cylinder 5 is rotatably installed on the collar 6. The end of the end fixing cylinder 5 away from the collar 6 is threadedly connected to the end of the core post 8.

[0037] In this embodiment of the invention, the through-through channels 9 of the through-through posts 8 facilitate the separate installation of the cable cores 10. Simultaneously, the staggered arrangement of the through-through channels 9 of the two through-through posts 8 avoids interference between the cable cores 10 of the two cable bodies 7 during installation, improving convenience. The inner sleeve 13, outer sleeve 14, and connecting push plate 26 allow the connecting push plate 26 to separate the cable cores 10 installed on the two through-through posts 8 in pairs. Furthermore, the transmission assembly drives the two outer sleeves 14 to rotate in opposite directions, and the connecting push plate 26 inside the two outer sleeves 14 drives the cable cores 10 to move in opposite directions, thereby enabling the cable cores 10 of the two cable bodies 7 to abut against each other and be electrically connected. This connection method is intelligent, reliable, and quick. In addition, the combination of the collar 6 and the end fixing cylinder 5 provides both protection and aesthetic appeal.

[0038] In summary, the present invention, through the design of staggered core-passing channels 9 and connecting push plates 26, achieves interference-free threading and automatic alignment electrical connection of cable cores 10, and has the advantages of intelligent and convenient operation and reliable connection.

[0039] like Figure 1-2 As shown in Figures 6-8, in a preferred embodiment of the present invention, the number of connecting push plates 26 fixed on the inner sleeve 13 is the same as the number of core-passing channels 9 opened on the core-passing column 8; initially, it is only necessary to connect the connecting push plates 26 on the two outer sleeves 14 one by one and separate the two core-passing channels 9 so as to meet the subsequent electrical connection requirements.

[0040] The two ends of the through-hole 9 are rounded to facilitate the insertion and removal of the cable core 10.

[0041] To improve the stability of the outer sleeve 14, the ends of the two outer sleeves 14 that are far apart are also rotatably connected to the core post 8.

[0042] It should be noted that in practical applications, the gap between the adaptive adjustment connecting push plate 26 and the cable core 10 is adjusted. This way, only a small angle needs to be rotated to ensure a reliable electrical connection and a secure, anti-slip grip on the cable core 10, preventing adjacent cable cores 10 from interfering with each other and improving reliability. Furthermore, the cable core 10 located in the area of ​​the intermediate connecting post 12 only needs to expose the electrical connection core, while the cable core 10 located within the core-passing channel 9 retains its insulation layer.

[0043] An elastic anti-slip sleeve is fixed on the inner side of the collar 6 to ensure the fit and stability of the collar 6 on the cable body 7. An annular groove 11 is provided on the outer side of the collar 6. The end of the end fixing cylinder 5 is rotatably connected to the annular groove 11. This prevents the collar 6 from twisting when the end fixing cylinder 5 is connected, and at the same time allows the collar 6 to pull the cable body 7 towards the core post 8 for reliable contact.

[0044] The transmission assembly includes an adjustment knob 2, a worm shaft 3, a worm wheel shaft 15, a worm 16, a bevel gear ring 23, a bevel gear 24, and a worm wheel 25. The outer sides of the two outer sleeves 14 are fixedly fitted with bevel gear rings 23. The inner wall of the cover 1 is rotatably mounted with a worm wheel shaft 15, and a worm wheel 25 is fixed on the worm wheel shaft 15. The end of the worm wheel shaft 15 is also fixed with a bevel gear 24 that meshes with both bevel gear rings 23. The cover 1 is also rotatably mounted with a worm shaft 3, and a worm 16 that meshes with the worm wheel 25 is fixed on the worm shaft 3. One end of the worm shaft 3 is fixed with an adjustment knob 2.

[0045] Furthermore, the worm shaft 3 and the worm wheel shaft 15 are arranged perpendicularly. To avoid unauthorized rotation of the adjustment knob 2, the worm shaft 3 is also damped and rotatably connected to the housing 1. To improve the convenience and reliability of operation, a scale (not shown) can be arranged on the housing 1 to easily indicate the rotation angle and initial position of the worm shaft 3.

[0046] After the cable core 10 is inserted, the adjusting knob 2 rotates the worm shaft 3. The worm 16 then drives the worm wheel 25 to rotate, causing the coaxial bevel gear 24 to drive the two bevel gear rings 23 to rotate in opposite directions. The connecting push plates 26 on both sides reverse at a certain angle, thus pushing the cable core 10 to bend and reliably connect electrically. Moreover, the bending and contact further prevents the cable core 10 from slipping. In addition, the worm 16 and worm wheel 25 have self-locking characteristics, preventing loosening after locking, ensuring high reliability.

[0047] like Figure 1-5 As shown in the preferred embodiment of the present invention, the low-altitude economic cable intelligent quick connector further includes an auxiliary fixing component for fixing the cable core 10 passing through the core post 8. The auxiliary fixing component includes a locking cylinder 4, a locking post 21, a locking plate 22, a side extension block 18, and a spring 19. The core post 8 has sliding openings 17 circumferentially distributed to correspond to the core passages 9. The locking plate 22 is slidably mounted on the sliding opening 17. Side cavities 20 are opened on both sides of the sliding opening 17. The two ends of the locking plate 22 are fixed with extensions into the side cavities 20. The inner side extension block 18 is provided with a spring 19 for elastic support of the side extension block 18 in the side cavity 20; a locking cylinder 4 is rotatably installed on the core-passing column 8, and multiple locking columns 21 are fixedly distributed circumferentially on the inner side of the locking cylinder 4; when the locking column 21 is not in contact with the locking plate 22, the locking plate 22 is separated from the core-passing channel 9 under the elastic force of the spring 19; when the locking cylinder 4 is rotated, the locking column 21 pushes the locking plate 22 to move, thereby causing the locking plate 22 to extend into the core-passing channel 9 and fix the cable core 10.

[0048] Furthermore, the inner end of the locking plate 22 is rounded to improve the reliability of fixing the cable core 10 and prevent damage to the cable core 10. The locking post 21 adopts a 1 / 2 cylindrical structure, and the outer end of the locking plate 22 adopts a central arc-shaped concave structure. When the locking post 21 is locked at the outer end of the locking plate 22, the locking plate 22 extends into the core-passing channel 9 and fixes the cable core 10. To make the locking cylinder 4 more reliable, both ends of the locking cylinder 4 are also damped rotatably connected to the core-passing post 8.

[0049] After the cable core 10 is inserted and connected to the push plate 26, the locking cylinder 4 can be rotated, which causes the locking pin 21 to push the locking plate 22 to move, so that the locking plate 22 extends into the core insertion channel 9 and fixes the cable core 10, thus completing the auxiliary fixation of the cable core 10 and improving the overall reliability.

[0050] The above embodiments of the present invention provide a smart quick connector for low-altitude economic cables, the working principle of which is as follows:

[0051] The cable cores 10 of the two cable bodies 7 are respectively inserted into the core-passing channels 9 on the core-passing posts 8 at both ends of the intermediate connecting post 12. Since the core-passing channels 9 on the two core-passing posts 8 are staggered, interference during cable core 10 insertion can be effectively avoided, improving the ease of cable insertion. During insertion, the portion of the cable core 10 located within the core-passing channel 9 retains the insulation layer, and only the insulation layer is stripped in the intermediate connecting area to expose the conductor.

[0052] After the cable core 10 is threaded through, operate the adjustment knob 2 to drive the worm 16 to rotate via the worm shaft 3. The worm 16 drives the worm wheel 25 to rotate, which in turn drives the coaxial worm wheel shaft 15 and bevel gear 24 to rotate. Since the bevel gear 24 simultaneously meshes with the bevel gear rings 23 on the outer walls of the two outer sleeves 14, it drives the two outer sleeves 14 to rotate in opposite directions. The connecting push plate 26, fixed to the inner side of the outer sleeve 14, rotates accordingly, pushing the exposed ends of the cable cores 10 on both sides to bend in opposite directions and abut against each other, achieving automatic alignment and reliable electrical connection. The bending structure also prevents the connection from loosening.

[0053] To enhance connection stability, the locking cylinder 4 can be further rotated, and the locking pin 21 fixed inside it pushes the locking plate 22 to slide in the sliding port 17 of the core-penetrating pin 8, and overcomes the elastic force of the spring 19 in the side cavity 20, so that the locking plate 22 extends into the core-penetrating channel 9, presses and fixes the cable core 10, and achieves auxiliary locking and anti-derailment.

[0054] The collar 6 is fitted onto the cable body 7. The end fixing cylinder 5 is threadedly connected to the end of the core post 8, which drives the collar 6 to be pressed, thus providing external protection, dust prevention, aesthetics, and assisting in tightening the cable.

[0055] In summary, this invention achieves interference-free installation of the cable core 10, automatic alignment and electrical connection, mechanical locking, and external protection through the coordinated operation of various components, making the operation intelligent, fast, and reliable.

[0056] The control of each component can be achieved using a PLC controller disclosed in the existing technology. There are no specific limitations on the model and circuit connection of each component, and they can be flexibly set in actual applications.

[0057] The circuits, electronic components, and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this invention does not involve any improvement to the software and methods.

[0058] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0059] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
