Description

Technical Field

[0001] This invention belongs to the field of circuit construction technology, and in particular relates to a quick-connection device for broken power distribution lines. Background Technology

[0002] Power distribution lines refer to the lines that transmit power from step-down substations to distribution transformers or from distribution substations to power-consuming units. During the installation and construction of electronic components for these lines, it is often necessary to deal with situations where cables or wires need to be extended.

[0003] Existing technology involves connecting two wires end-to-end using terminals, then applying pressure to the terminals with crimping pliers to deform them, thus achieving the connection. However, commercially available wiring equipment typically requires manual operation, resulting in a high failure rate, weak connections, and low efficiency. There is an urgent need to design a quick-connect device for broken wires in power distribution lines to improve these issues, ensuring a secure connection while increasing wiring efficiency on construction sites. Summary of the Invention

[0004] The purpose of this invention is to solve the technical problems of existing wiring devices, such as loose wiring, low wiring efficiency, and inconvenience of use, and to propose a quick-connection device for power distribution line disconnection.

[0005] To achieve the objective of this invention, a quick-connect device for disconnected power distribution lines is disclosed, comprising an outer casing and an inner casing. The inner casing is fixedly connected to the middle position of the bottom inner wall of the outer casing. A wire insertion slot is provided at the middle position of the top of both sides of the outer casing. A material placement platform is provided inside the inner casing, and a connecting piece is provided at the top of the material placement platform. A cover plate is longitudinally slidably connected to the middle position of the top of the outer casing. Insert plates are fixedly connected to both sides of the bottom of the cover plate. A motor is fixedly connected to the bottom side of one insert plate near the other insert plate. A bidirectional screw is driven to the output end of the motor. The outer wall of the bidirectional screw has two sections of threads with opposite directions. Two symmetrically arranged clamps are threaded to the body of the bidirectional screw. An arc-shaped pressure groove is provided on the side of the two clamps that are close to each other. Two indentation knives are fixedly connected inside the two arc-shaped pressure grooves. Two parallel guide rods are fixedly connected to the bottom of the side of the two insert plates that are close to each other. The two clamps are laterally slidably connected to the two guide rods.

[0006] Furthermore, viewing windows are provided on the top of both sides of the outer casing, and symmetrically arranged positioning grooves are fixedly connected to the top of the inner walls on both sides of the two viewing windows. Two insert plates are respectively inserted into the positioning grooves on both sides of the outer casing.

[0007] Furthermore, a handle is fixedly connected to the middle position of the top of the cover plate; the height of the insert plate is equal to that of the positioning groove, and the height of the positioning groove is less than the height of the inner wall of the viewing window.

[0008] Furthermore, a controller is fixedly connected to the middle position of the bottom of the cover plate; a pressure sensor is fixedly connected to the top of one of the two clamps on the side with the arc-shaped pressure groove, and the signal output terminal of the pressure sensor is connected to the signal output terminal of the controller through a signal line.

[0009] Furthermore, a limiting cylinder is fixedly connected to the middle position of the bottom of the inner box, a lifting rod is slidably connected to the top of the limiting cylinder, the top of the lifting rod is fixedly connected to the middle position of the bottom of the material placement platform, a spring is fixedly connected to the bottom of the lifting rod, and the bottom of the spring is fixedly connected to the limiting cylinder.

[0010] Furthermore, an iron core is fixedly connected to the middle position of the bottom of the lifting rod, and an electromagnet is fixedly connected to the bottom of the limiting cylinder, with the electromagnet positioned directly below the iron core.

[0011] Furthermore, positioning corner plates are fixedly connected to the four corners of the top inner wall of the inner box, and the four corners of the material placement platform are respectively located below the four positioning corner plates. Four positioning pins distributed in a rectangular pattern are fixedly connected to the top of the material placement platform. The body of the connecting piece has four positioning holes distributed in a rectangular pattern, and the four positioning pins are respectively inserted into the four positioning holes. Positioning adhesive is glued to the middle position of the top of the connecting piece.

[0012] Furthermore, threaded holes are provided at the middle position of the top of both clamps, and the threads on the inner walls of the two threaded holes are respectively adapted to the two sections of threads on the bidirectional screw body; guide holes are provided on both sides of the top of both clamps, and the same guide rod is inserted into the guide hole on the same side of the two clamps.

[0013] Furthermore, each of the four indentation knives has evenly distributed indentation teeth on one side of its blade; the bottom of both sides of the connecting piece is provided with symmetrically distributed first guide slopes; the bottom of each of the four indentation knives has a second guide slope on one side of its blade; and the bottom of both clamps is provided with a spade blade on one side of their respective sides.

[0014] Furthermore, resistance heaters are fixedly connected to both sides of the bottom of the material placement platform; the interior of the inner box is filled with an insulation layer.

[0015] Compared with the prior art, the significant advancement of this invention lies in: 1) By setting up a motor, a bidirectional screw, clamps, and an arc-shaped pressure groove, the two wires to be connected are inserted into the insertion slots on both sides of the outer casing, and the wires are placed end to end on the top of the connecting piece. The motor drives the bidirectional screw to rotate, and the two clamps move closer to each other. During this process, the guide rod limits the movement direction of the clamps to prevent the clamps from deflecting. The connecting piece deforms after being squeezed, and the two sides of the connecting piece curl upwards along the inner wall of the arc-shaped pressure groove to cover the connection points of the two guides. After the connecting piece is covered, the two indentation knives further squeeze the connecting piece, pressing the part of the connecting piece squeezed by the indentation knives into the wire. This completes the connection of the two wires. Then, the motor controls the bidirectional screw to reverse, moving the two clamps apart. At this point, the connected wires can be pulled out from one side of the outer casing. The wire connection process is automated, eliminating the need for construction personnel to manually press the terminals with wiring pliers. This improves the wiring efficiency on the construction site while ensuring a secure connection. 2) This power distribution line disconnection quick-connection device, by setting a viewing window, a plug plate, and a positioning groove, allows the plug plate to slide into the outer casing via the positioning groove. The viewing window allows observation of the clamp's operation inside the outer casing. The handle allows the cover plate to be pulled up, causing the plug plate to rise from the positioning groove, thereby pulling the clamp out of the outer casing. The device features detachable clamp installation, facilitating maintenance of the motor and double-wire screw, ensuring precise operation of the device, and extending its service life. Additionally, when the connected wire is too long, the wire can be pulled away from the top of the insertion slot by lifting the clamp. 3) This power distribution line disconnection quick-connection device, equipped with a pressure sensor, spring, electromagnet, and iron core, allows for automatic clamp separation when two clamps connect the wire. The pressure sensor's force-sensitive element detects contact between the pressure sensor and the other clamp, transmitting a signal back to the controller. The controller then reverses the motor, automatically separating the clamps, further simplifying the wire connection process and addressing continuous wiring operations. At the same time, multiple connecting plates can be placed on the top of the material placement platform at one time. When the number of connecting plates on the top of the material placement platform increases, the pressure on the spring increases synchronously and generates compression deformation. The lifting rod drives the material placement platform to descend, and multiple connecting plates descend synchronously. When the number of connecting plates decreases, the pressure on the spring decreases, and the lifting rod drives the material placement platform to rise, realizing the automatic feeding function in continuous operation of the device. When placing connecting plates on the material placement platform, the electromagnet is energized and attracts the iron core downward, pulling the lifting rod down along the wall of the limiting cylinder, controlling the material placement platform to descend directly to the lower limit, reducing the resistance during the installation of connecting plates. After the connecting plates are installed, the electromagnet is de-energized, and the spring can restore its elastic potential energy.4) This type of quick-connect device for disconnected power distribution lines incorporates a resistance heater and an insulation layer. The resistance heater heats the material placement platform and connecting plates, making the connecting plates more prone to deformation. The insulation layer retains the heat generated by the resistance heater, optimizing its heating efficiency.

[0027] Reference Figure 1-7 A quick-connection device for disconnected power distribution lines includes an outer casing 1 and an inner casing 2. The inner casing 2 is fixedly connected to the middle position of the bottom inner wall of the outer casing 1. Wire insertion slots 5 are provided at the middle positions of the top of both sides of the outer casing 1.

The outer wall of the bidirectional screw 10 has two sections of threads with opposite directions. The screw body of the bidirectional screw 10 is threadedly connected to two symmetrically arranged clamps 12. The two clamps 12 are provided with arc-shaped pressing grooves 34 on the side close to each other. Two indentation knives 14 are fixedly connected inside the two arc-shaped pressing grooves 34.

The height of the insert plates 4 is equal to the height of the positioning grooves 3, and the height of the positioning grooves 3 is less than the height of the inner walls of the viewing windows 30. A controller 7 is fixedly connected to the middle position of the bottom of the cover plate 6. A pressure sensor 13 is fixedly connected to the top of one side of the clamp 12 where an arc-shaped pressure groove 34 is provided. The pressure sensor 13... The signal output terminal is connected to the signal output terminal of the controller 7 via a signal line. A limit cylinder 29 is fixedly connected to the middle position of the bottom of the inner box 2. A lifting rod 20 is slidably connected to the top of the limit cylinder 29. The top of the lifting rod 20 is fixedly connected to the middle position of the bottom of the material placement platform 16. A spring 18 is fixedly connected to the bottom of the lifting rod 20. The bottom of the spring 18 is fixedly connected to the limit cylinder 29. An iron core 28 is fixedly connected to the middle position of the bottom of the lifting rod 20. An electromagnet 19 is fixedly connected to the bottom of the limit cylinder 29. The electromagnet 19 is located directly below the iron core 28. Positioning corner plates 31 are fixedly connected to the four corners of the top inner wall of the inner box 2. The four corners of the platform 16 are located below the four positioning angle plates 31. Four rectangularly distributed positioning pins 21 are fixedly connected to the top of the platform 16. The body of the connecting piece 15 has four rectangularly distributed positioning holes 24, into which the four positioning pins 21 are inserted. Positioning adhesive 25 is bonded to the center of the top of the connecting piece 15. Threaded holes 23 are opened at the center of the top of each of the two clamps 12. The threads on the inner walls of the two threaded holes 23 are respectively adapted to the two sections of threads on the body of the bidirectional screw 10. Guide holes 22 are opened on both sides of the top of each of the two clamps 12. The guide holes on the same side of the two clamps 12... The same guide rod 11 is inserted inside the 22. The clamp 12 achieves a sliding connection with the guide rod 11 through the guide hole 22 and a threaded connection with the bidirectional screw 10 through the threaded hole 23. The four indentation knives 14 have evenly distributed indentation teeth 35 on one side of their blades. The bottom of both sides of the connecting piece 15 is provided with symmetrically distributed first guide slopes 26. The bottom of one side of the blades of the four indentation knives 14 is provided with second guide slopes 32. The bottom of the two clamps 12 is provided with scraper blades 33 on the side closer to each other. The bottom of the material placement platform 16 is fixedly connected to both sides of the bottom with resistance heaters 27. The interior of the inner box 2 is filled with a heat insulation layer 17.

[0029] In use, the two wires to be connected are inserted into the insertion slots 5 on both sides of the outer casing 1, and the wires are placed end to end on top of the connecting piece 15. The motor 9 drives the bidirectional screw 10 to rotate, and the two clamps 12 move closer to each other. During this process, the guide rod 11 limits the movement direction of the clamps 12 to prevent the clamps 12 from deflecting. The connecting piece 15 deforms after being squeezed, and the two sides of the connecting piece 15 curl upward along the inner wall of the arc-shaped pressure groove 34 to cover the connection points of the two guides. After the connecting piece 15 is covered, the two indentation knives 14 further squeeze the connecting piece 15, pressing the part of the connecting piece 15 squeezed by the indentation knives 14 into the wire body, thus completing the connection of the two wires. When the two clamps 12 complete the connection of the wires... When the force-sensitive element of pressure sensor 13 detects that pressure sensor 13 has made contact with another clamp 12, the signal is transmitted back to controller 7. Controller 7 then controls motor 9 to reverse, causing clamp 12 to automatically separate, further simplifying the wire connection process. At this point, the connected wire can be pulled out from one side of the outer casing 1. The operation of clamp 12 inside the outer casing 1 can be observed through viewing window 30. The cover plate 6 can be pulled up using handle 8, causing the insertion plate 4 to rise from the positioning slot 3, thereby pulling clamp 12 out of the outer casing 1. This achieves detachable installation of clamp 12. Furthermore, when the connected wire is too long, the wire can be pulled away from the top of the insertion slot 5 of the outer casing 1 by pulling clamp 12 upwards. When facing continuous wiring operations, multiple connecting pieces 15 can be placed on the top of the material placement platform 16 at once. As the number of connecting pieces 15 on the top of the material placement platform 16 increases, the pressure on the spring 18 increases synchronously and generates compression deformation. The lifting rod 20 drives the material placement platform 16 to descend, and multiple connecting pieces 15 descend synchronously. When the number of connecting pieces 15 decreases, the pressure on the spring 18 decreases, and the lifting rod 20 drives the material placement platform 16 to rise, realizing the automatic feeding function in continuous operation of the device. When placing connecting pieces 15 on the material placement platform 16, the electromagnet 19 is energized and attracts the iron core 28 downward, pulling the lifting rod 20 down along the wall of the limiting cylinder 29, controlling the material placement platform 16 to descend directly to the lower limit, reducing the time required for installing connecting pieces 15. The resistance is such that after the connecting piece 15 is installed, the electromagnet 19 is de-energized, and the spring 18 can recover its elastic potential energy. The upper limit of the material placement platform 16 is limited by the positioning angle plate 31. The positioning pin 21 is inserted into the positioning hole 24 for positioning between the connecting piece 15 and the material placement platform 16. When multiple connecting pieces 15 are placed, the positioning glue 25 plays a role in connecting and fixing between different connecting pieces 15, without affecting the separation between the connecting pieces 15. When the clamp 12 moves towards each other, the two shovel blades 33 move to the bottom of the two first guide slopes 26 respectively, and shovel up the edge of the connecting piece 15 along the two first guide slopes 26, guiding the first guide slopes 26 to fit against the inner wall of the arc-shaped pressing groove 34. When the connecting piece 15 is about to contact the indentation knife 14,The first guide slope 26 first adheres to the second guide slope 32 and slides relative to it during the deformation of the connecting piece 15, to prevent the blade of the indentation knife 14 from affecting the continuity of the deformation of the connecting piece 15. The resistance heater 27 heats the material placement platform 16 and the connecting piece 15, making it easier for the connecting piece 15 to deform. The insulation layer 17 retains the heat generated by the resistance heater 27, optimizing the heating efficiency of the resistance heater 27.
