Description

Technical Field

[0001] The invention relates to the technical field of low-voltage cables, in particular to a low-voltage circuit cable which is convenient and quick to connect. Background Art

[0002] In the current electrical construction and maintenance scenarios, the traditional low-voltage circuit cable connection method has many inconveniences. Cables are conductors covered with insulation layers, protective layers, shielding layers, etc., used to transmit power or signal currents and signal voltages. According to voltage, they can be divided into high-voltage cables and low-voltage cables. Although low-voltage cable lines are more expensive and more difficult to lay and maintain than low-voltage overhead lines and low-voltage overhead insulated lines, they are widely used in low-voltage distribution systems because of their reliable operation, no poles, no ground occupation, no obstruction of appearance, and less impact from the outside world. With the acceleration of industrialization and the widespread application of various electrical equipment, the requirements for the timeliness and stability of power supply are becoming more and more stringent. For example, in scenarios such as sudden power outages in production lines of large factories, temporary power access to urban infrastructure, and circuit transformation in home decoration, traditional cable connections require a lot of time for operations such as stripping, winding, and tightening nuts, and the operation process requires professional tools and certain technical experience, which not only prolongs the power outage time and increases economic losses, but also may cause safety hazards due to improper operation. In this context, low-voltage circuit cables that are easy to connect and quick to connect have become an urgent need.

[0003] At present, most cable products have not fully considered the quick connection function in their design. Even some products claiming to have quick-connect characteristics still have problems such as unstable connection, poor conductivity, and poor compatibility. This makes some quick-connect cables easy to loosen after connection, resulting in increased contact resistance and severe heat generation, affecting power transmission efficiency and safety. In addition, some products can only be used for cables of specific specifications and cannot meet diverse construction needs. Therefore, it is necessary to propose a low-voltage circuit cable that is easy to connect and quick-connect. Summary of the invention

[0004] The purpose of the present invention is to provide a low-voltage circuit cable that is convenient for quick connection, so as to solve the problem proposed in the above-mentioned background technology that most cable products have not fully considered the quick connection function in their design.

[0010] Preferably, the side end of the outer protective connection end is rotatably connected with a magnetic connection ring, the inner wall of the magnetic connection ring and the outer peripheral surface of the conductor insulation protection connector form a tight connection, and a twist lock ring is tightly connected on the surface of the magnetic connection ring, and a micro-drive motor is installed inside the twist lock ring. The magnetic connection ring is used to form a magnetic connection with the inner wall surface of the outer protective connection end on the other side when the two sets of outer protective connection ends are docked.

[0011] Preferably, a docking twist bolt column is fastened to the inner surface of the outer protective connection end on the other side, and a sliding lock end is fastened to the outer wall surface of the docking twist bolt column. The side end of the docking twist bolt column and the output end of the micro-drive motor form a key connection. With the cooperation of the micro-drive motor and the docking twist bolt column, the sliding lock end automatically locks along the track lock track opened on the surface of the twist lock ring.

[0012] Preferably, docking cones are installed on the left and right end surfaces of the outer protective connection end, an elastic spring is installed inside the docking cone, and a docking buckle plate is fastened to the side end of the docking cone.

[0013] Preferably, the left and right end surfaces of the outer protective connection end on the other side are provided with docking buckle grooves, and the docking cone drives the docking buckle plate and the docking buckle groove to form a buckling connection.

[0014] Preferably, a through hole is provided on the top surface of the conductor insulation protection connector, and the through hole is used to allow the docking twist bolt column to pass through the through hole and the twist lock ring to form a docking when the outer protection connection end is docked.

[0015] Preferably, the distance adjustment control component includes:

[0016] A micro-drive brushless motor, a drive insulating gear and a rotating insulating gear. The micro-drive brushless motor is installed inside the side convex edge of the conductor insulation protection connector. The output end of the micro-drive brushless motor drives the drive insulating gear to rotate and forms a meshing connection with the rotating insulating gear.

[0017] Preferably, the side wall surface of the rotating insulating gear is fastened with a connecting short column, the side end of the connecting short column is inserted and connected with a rotating groove track plate, the side end of the connecting short column and the clamping carbon brush form a fastened connection, the side end of the clamping carbon brush is fastened with a stabilizing sliding column, and the side end of the stabilizing sliding column is inserted and connected with a track slide groove stabilizing plate.

[0019] Preferably, a docking completion detection end is installed on the side end of the outer protective connection end on the other side, and an indicator light is installed on the surface of the docking completion detection end.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. In the present invention, with the cooperation of the magnetic connection end and the magnetic fixed end, due to the magnetic effect of the magnetic connection end, the outer protection connection end of the first low-voltage circuit cable body will automatically be attracted to the magnetic connection end inside the outer protection connection end on the side of the second low-voltage circuit cable body, and then the magnetic connection end starts to slide along the three groups of slide grooves opened on the outer wall surface of the conductor insulation protection connector, and forms a magnetic connection setting with the magnetic fixed end fastened and connected on the surface of the slide groove, further fixing the connection between the two cables to prevent them from accidental separation. The operator only needs to gently push the cable to assist the magnetic attraction process to ensure the initial stable docking of the two. This process is fast and does not require precise alignment operations, which greatly saves time and can be easily completed even in dark or narrow spaces. Then, the docking cone is popped outward under the elastic force of the elastic spring, and the docking buckle plate at its side end is embedded in the docking buckle groove opened on the surface of the outer protection connection end on the other side, so as to achieve further precise positioning and mechanical buckling, and effectively prevent the two cables from being in a state of being disconnected. Relative displacement occurs in subsequent operations to ensure the stability and accuracy of the connection. At the same time, the micro-drive motor receives the trigger signal generated by the key connection between its output end and the docking twist bolt column, and starts to operate, causing the docking twist bolt column to rotate accordingly, and then the sliding lock end connected to the outer wall surface of the docking twist bolt column is tightened. Under the guidance of the rotation of the docking twist bolt column and the track lock path opened on the surface of the twist lock ring, it automatically slides along the lock path, and finally achieves complete locking, firmly fixing the connection between the two cables. This process does not require additional complex tools and has a high degree of automation, further improving the connection efficiency and reliability, and realizing the overall "fool-style" operation of cable docking, which greatly simplifies the connection process, reduces the skill requirements for operators, ensures mechanical stability during the connection process, prevents accidental disconnection of the cable, and also ensures the stability of the internal electrical connection, ensuring that power or signal transmission is not interfered with, and improving the survivability of the entire low-voltage circuit cable connection system in harsh environments.

[0022] 2. In the present invention, by cooperating with the pitch control component, when the initial magnetic docking is completed and the signal mechanism for starting the micro-drive brushless motor is triggered, the micro-drive brushless motor starts to operate. After the micro-drive brushless motor operates, its output end drives the driving insulating gear to rotate at a high speed. Since the driving insulating gear and the rotating insulating gear are meshed with each other, the rotating insulating gear rotates synchronously under the action of the gear transmission. The rotation of the rotating insulating gear drives the connecting short column fastened to the side wall surface to make a circular motion together. While the connecting short column makes a circular motion, it drives the clamping carbon brush fastened thereto to move, so that the clamping carbon brush makes a relatively complex curved motion along the trajectory defined by the rotating groove track plate on the one hand, so that the trajectory is adjusted according to the optimal The optimized design ensures that the clamping carbon brush can fully cover the surface of the conductor connector. At the same time, the stabilizing slide column at its side end slides in the slide groove of the track slide groove stabilizing plate to ensure the stability of the clamping carbon brush movement. In this process, the clamping carbon brush is in close contact with the outer wall surface of the first conductor connector and the second conductor connector, and good conductivity is ensured by removing the oxide layer and impurities, thereby improving the electrical performance of the cable connection, reducing the safety hazards such as heat and power loss caused by increased contact resistance, extending the reliable operation time of the cable connection, and reducing maintenance costs. It eliminates the need for operators to replace connection equipment due to changes in cable specifications, and can be conveniently used in various electrical engineering projects, broadening the application scope of the product and improving resource utilization.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Embodiment 1: In the present invention, referring to Figure 1 - Fig.10 Shown: A convenient and quick-connect low-voltage circuit cable, including:

[0036] A first low-voltage circuit cable body 1 is installed at the left end of the outer sheath connection end 2 and is connected to a second low-voltage circuit cable body 5 through the outer sheath connection end 2 to form a complete closed electrical circuit;

[0037] The outer protection connection end 2 is provided in two groups, and the two groups of outer protection connection ends 2 are installed on the outer peripheral side of the conductor insulation protection connection piece 6, and are used to connect the first conductor connection piece 7 and the second conductor connection piece 11 through the conductor insulation protection connection piece 6;

[0038] The distance control assembly 10 is installed in the inner side wall slot of the conductor insulation protection connector 6, and is used to further increase the docking stability of the first conductor connector 7 and the second conductor connector 11, and clean the outer wall surface of the first conductor connector 7 and the second conductor connector 11 by clamping the carbon brush 105 to ensure their conductive stability;

[0039] The magnetic connection end 21 forms three groups of equally divided and encircled arrangements inside the outer protective connection end 2 on the side of the second low-voltage circuit cable body 5. When the first low-voltage circuit cable body 1 and the second low-voltage circuit cable body 5 are docked, the magnetic connection end 21 will slide along the three groups of slide grooves 12 opened on the outer wall surface of the conductor insulation protection connector 6, and form a magnetic connection arrangement with the magnetic fixed end 13 fastened to the surface of the slide groove 12.

[0040] In a specific scheme, one end of the first low-voltage circuit cable body 1 is brought close to the corresponding end of the second low-voltage circuit cable body 5 so that the outer protective connection ends 2 of the two are aligned with each other. At this time, due to the magnetic effect of the magnetic connection end 21, the outer protective connection end 2 of the first low-voltage circuit cable body 1 will automatically be attracted to the magnetic connection end 21 inside the outer protective connection end 2 on the side of the second low-voltage circuit cable body 5, and then the magnetic connection end 21 starts to slide along the three groups of slide grooves 12 opened on the outer wall surface of the conductor insulation protection connector 6, and forms a magnetic connection setting with the magnetic fixed end 13 fastened on the surface of the slide groove 12, thereby further fixing the connection between the two cables to prevent them from being accidentally separated. The operator The operator only needs to gently push the cable to assist the magnetic attraction process to ensure that the two are initially and stably connected. This process is fast and does not require precise alignment operations, which greatly saves time and can be easily completed even in dark or narrow spaces. As the magnetic attraction process is completed, the first conductor connector 7 and the second conductor connector 11 are basically close but not yet completely and accurately connected, so that the distance control component 10 is operated to accurately control the connectivity between the first conductor connector 7 and the second conductor connector 11 through adjustment to achieve the best electrical connection spacing, ensure a close fit, and avoid poor contact and heating problems caused by loose connections. In the adjustment process, the clamping carbon brush 10 in the distance control component 10 5 will be in close contact with the outer wall surfaces of the first conductor connector 7 and the second conductor connector 11. When the distance control component 10 is actuated, the clamping carbon brush 105 is in close contact with the conductor connectors, and automatically wipes and cleans the outer wall surfaces of the first conductor connector 7 and the second conductor connector 11 as the relative movement is performed, effectively removing the oxide layer, dust, impurities, etc. that may exist on the metal surface, ensuring the conductive stability between the conductors, reducing contact resistance, reducing power loss and heating risks, and realizing the "fool-style" operation of cable docking as a whole, greatly simplifying the connection process, reducing the skill requirements for operators, and ensuring good conductivity by removing the oxide layer and impurities. It fundamentally improves the electrical performance of cable connections, reduces safety hazards such as heat and power loss caused by increased contact resistance, extends the reliable operation time of cable connections, reduces maintenance costs, and eliminates the need for operators to replace connection equipment due to changes in cable specifications. It can be easily used in various electrical engineering projects, broadens the application range of the product, improves resource utilization, reduces equipment procurement and management costs during construction, ensures mechanical stability during the connection process, prevents accidental disconnection of cables, and ensures the stability of internal electrical connections, ensuring that power or signal transmission is not interfered with, and improves the survivability of the entire low-voltage circuit cable connection system in harsh environments.

[0041] Embodiment 2: In the present invention, according to Figure 4 - Figure 8As shown, the side end of the outer protection connection end 2 is rotatably connected with a magnetic connection ring 17, the inner wall of the magnetic connection ring 17 and the outer peripheral surface of the conductor insulation protection connection piece 6 form a tight connection, and a twist lock ring 18 is tightly connected on the surface of the magnetic connection ring 17. A micro drive motor 19 is installed inside the twist lock ring 18. The magnetic connection ring 17 is used to form a magnetic connection with the inner wall surface of the outer protection connection end 2 on the other side when the two sets of outer protection connection ends 2 are docked.

[0042] A docking twist bolt column 22 is fastened to the inner surface of the outer protective connection end 2 on the other side, and a sliding lock end 23 is fastened to the outer wall surface of the docking twist bolt column 22. The side end of the docking twist bolt column 22 and the output end of the micro-drive motor 19 form a key connection. With the cooperation of the micro-drive motor 19 and the docking twist bolt column 22, the sliding lock end 23 automatically locks along the track lock track opened on the surface of the twist lock ring 18.

[0043] A butt cone 14 is installed on the left and right surfaces of the outer protective connection end 2 , an elastic spring 15 is installed inside the butt cone 14 , and a butt buckle plate 16 is fastened to the side end of the butt cone 14 .

[0044] The left and right end surfaces of the outer protective connection end 2 on the other side are provided with butt buckle grooves 20 , and the butt cone 14 drives the butt buckle plate 16 and the butt buckle grooves 20 to form a buckled connection.

[0045] A through hole 24 is provided on the top surface of the conductor insulation protection connector 6. The through hole 24 is used to allow the connecting twist bolt 22 to pass through the through hole 24 and the twist lock ring 18 to form a connection when the outer protection connection end 2 is connected.

[0046] In a specific scheme, when the above-mentioned preliminary docking is completed, the docking cone 14 pops outward under the elastic force of the elastic spring 15, and the docking buckle plate 16 at its side end is embedded in the docking buckle groove 20 opened on the surface of the outer protective connection end 2 on the other side, to achieve further precise positioning and mechanical buckling, effectively preventing the two cables from relative displacement in subsequent operations, ensuring the stability and accuracy of the connection. At the same time, the micro-drive motor 19 receives the trigger signal generated by the key connection between its output end and the docking twist bolt column 22, and starts to operate, so that the docking twist bolt column 22 rotates accordingly, and then the sliding lock end 23 is fastened to the outer wall surface of the docking twist bolt column 22. Under the guidance of the rotation of the docking twist bolt column 22 and the track lock track opened on the surface of the twist lock ring 18, it automatically slides along the lock track, and finally achieves complete locking, and the connection between the two cables is firmly fixed. This process does not require additional complex tools, has a high degree of automation, and further improves the connection efficiency and reliability.

[0047] Embodiment 3: In the present invention, according to Fig. 9 and Fig.10 As shown, the distance control assembly 10 includes:

[0048] A micro-drive brushless motor 101, a drive insulating gear 102 and a rotating insulating gear 103. The micro-drive brushless motor 101 is installed inside the side convex edge of the conductor insulation protection connector 6. The output end of the micro-drive brushless motor 101 drives the drive insulating gear 102 to rotate and forms a meshing connection with the rotating insulating gear 103.

[0049] The side wall surface of the rotating insulating gear 103 is fastened with a connecting short column 107, the side end of the connecting short column 107 is inserted and connected with a rotating groove track plate 106, the side end of the connecting short column 107 and the clamping carbon brush 105 form a fastened connection, the side end of the clamping carbon brush 105 is fastened with a stabilizing sliding column, and the side end of the stabilizing sliding column is inserted and connected with a track slide groove stabilizing plate 104.

[0050] In a specific solution, when the above-mentioned pitch control component 10 is in operation, after the initial magnetic docking is completed and the signal mechanism of the micro-drive brushless motor 101 is triggered to start, the micro-drive brushless motor 101 starts to operate. After the micro-drive brushless motor 101 operates, its output end drives the driving insulating gear 102 to rotate at a high speed. Since the driving insulating gear 102 and the rotating insulating gear 103 are meshed with each other, the rotating insulating gear 103 rotates synchronously therewith under the action of the gear transmission. The rotation of the rotating insulating gear 103 drives the connecting short column 107 fastened to the side wall surface to make a circular motion together. While the connecting short column 107 is making a circular motion, it drives the clamping carbon brush 105 fastened thereto to move, so that the clamping carbon brush 105 makes a relatively complex curved motion along the trajectory defined by the rotating groove track plate 106 on the one hand, so that the trajectory is optimized according to the design to ensure that the clamping carbon brush 105 can fully cover the surface of the conductor connector. At the same time, the stabilizing slide column at its side end slides in the slide groove of the track slide groove stabilizing plate 104 to ensure that the clamping carbon brush 105 The stability of movement, and in this process, the clamping carbon brush 105 is in close contact with the outer wall surface of the first conductor connector 7 and the second conductor connector 11. Relying on the soft texture, good conductivity and moderate friction characteristics of the carbon brush itself, the oxide layer, dust, impurities, etc. on the metal surface are automatically and efficiently wiped off to ensure the conductive stability between the conductors. With the continuous movement of the clamping carbon brush 105, the circular motion trajectory of the connecting short column 107 is converted into a precise adjustment of the distance between the first conductor connector 7 and the second conductor connector 11 through the exquisite design of the groove track plate 106. When the preset optimal electrical connection spacing is reached (the spacing can be optimized and set through preliminary experiments and built into the control system. The control system determines whether the target spacing is reached based on the number of gear rotations or other suitable sensor feedback), the micro-drive brushless motor 101 stops running. At this time, the conductor connectors of the two cables are tightly fitted, completing the dual tasks of precise distance adjustment and cleaning, and realizing stable and reliable electrical connection. The cable connection is completed and can be put into normal use.

[0052] A docking completion detection terminal 3 is installed on the side end of the outer protective connection terminal 2 on the other side, and an indicator light 4 is installed on the surface of the docking completion detection terminal 3.

[0053] In the specific scheme, during the above docking, the first sealing ring 8 and the second sealing ring 9 in the outer protective connection end 2 are squeezed on both sides to tightly fit the inner wall of the wire core body 25 and the outer protective connection end 2, forming a reliable double-layer sealing structure, further isolating the external environment, ensuring the stability of the internal electrical connection, and avoiding problems such as short circuit and leakage caused by water vapor and dust. When the cable connection operation is basically completed, the docking completion detection end 3 automatically starts the detection program, so that it uses the built-in electromagnetic induction sensor to detect the key parameters of the cable connection according to the detection principle, such as whether the pressure at the connection part reaches a stable and reliable value, whether there is normal current passing, whether the magnetic connection is in place, etc. When the test result shows that the cable connection meets the preset standard, the docking completion detection end 3 immediately sends a signal to the indicator light 4, and the indicator light 4 lights up (usually green), intuitively informing the operator that the connection is successful and the cable can be put into normal operation. When an abnormality is detected, the indicator light 4 lights up in a warning color (such as red), and can be matched with a simple buzzer alarm, so that the operator can quickly troubleshoot the problem and reconnect the operation.

[0054] The wiring diagram of the built-in electromagnetic induction sensor, micro-drive brushless motor 101 and micro-drive motor 19 in the present invention is common knowledge in the field, and its working principle is a well-known technology. The model is selected according to the actual use, so the control method and wiring arrangement of the built-in electromagnetic induction sensor, micro-drive brushless motor 101 and micro-drive motor 19 will not be explained in detail.

[0055] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
