Description

Technical Field

[0001] This invention relates to the field of conductive connections, specifically to an energy-saving power fitting. Background Technology

[0002] Copper busbars and wires are conductive components. To meet conductivity requirements and achieve current transmission and power distribution between electrical circuits, conductive connections between copper busbars and multiple wires are necessary. However, existing conductive connection methods typically rely on bolts to press the wires tightly against the surface of the copper busbar, thus achieving conductive connection between the busbar and the wires. When multiple wires need to be connected, operators must tighten the bolts one by one to fix each wire to the copper busbar, a cumbersome process that makes conductive connections inconvenient. Furthermore, to accommodate bolted connections, copper lugs must be pre-installed on the ends of the wires before connection work can begin, adding an extra step and further reducing the ease of conductive connection. Summary of the Invention

[0006] Preferably, the cable support includes multiple fixing blocks linearly arrayed and fixedly installed at the rear end of the support plate. Each fixing block has a clamp fixedly installed at its upper end. Each fixing block has a slide rail slidably installed through it. One end of the slide rail is fixedly installed with a clamp plate. A gathering frame is provided behind the support plate. Multiple cable support grooves are linearly arrayed and fixedly installed at the upper end of the gathering frame.

[0007] Preferably, guide shells are fixedly installed at the rear ends of the two fixed blocks on both sides, and guide cores are slidably installed inside the guide shells. The guide cores extend from the ends of the guide shells and are fixed to the gathering frame.

[0008] Preferably, a guide seat is elastically installed near the middle of the lower end of the bearing plate, a main pusher frame is rotatably installed at the end of the guide seat, a pusher plate is slidably installed through the lower parts of the plurality of fixed blocks, the end of the main pusher frame is rotatably connected to the pusher plate, an auxiliary pusher frame is rotatably installed between the pusher plate and the gathering frame, a curved tongue extends from the side of the guide seat, a lug is provided below the curved tongue, and the lug is fixed to the threaded sleeve below.

[0009] Preferably, a connecting frame is fixedly installed at the other end of the carriage, one end of the connecting frame is pressed against the clamp, and an arc-shaped plate is fixedly installed at the other end of the connecting frame. A wire clamping post is provided on the side of the arc-shaped plate, and a column plate is fixedly installed at the lower end of the wire clamping post. The column plate is fixed to the pusher plate.

[0010] Preferably, a guide post is fixedly installed at the lower end of the support plate near the middle, the guide seat is slidably installed on the outer surface of the guide post, and a return spring is wound around the outer side of the guide post. The two ends of the return spring are fixed to the support plate and the guide seat, respectively.

[0011] Preferably, rubber pads are provided on the opposite surfaces of the clamping plate and the clamping seat, as well as on both sides of the inside of the cable tray.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. First, engage the conductive base with the copper busbar. At this point, the conductive post on the conductive base aligns with the wiring hole on the copper busbar. Then, place the ends of multiple wires into the U-shaped guide seats on the conductive bases. Next, rotate the threaded rod. The symmetrical arrangement of the threads at both ends of the threaded rod drives the two threaded sleeves to move towards each other, which in turn drives the two ring sleeves to move towards each other. This allows the upper ring sleeve to move the pressure block on the upper frame downwards, clamping the wires into the U-shaped guide seats. The lower ring sleeve moves the top plate on the lower frame upwards, pressing it against the copper busbar, thus fixing the conductive base to the copper busbar. This connects multiple wires to the copper busbar, completing the conductive connection. This process allows multiple wires to be connected to the copper busbar simultaneously, eliminating the need to tighten each bolt individually to connect each wire to the copper busbar, effectively facilitating the conductive connection. Furthermore, during connection, the wires can be directly connected to the copper busbar without needing to add copper lugs to the ends of the wires before connection, further simplifying the conductive connection.

[0013] 2. When placing the end of the wire into the U-shaped guide seat on the conductive base, the wire can be pressed into the wire support groove and clamped between the clamp and the plate simultaneously, so that the end of the wire is always in the U-shaped guide seat to wait for connection, thereby preventing the wire from slipping out during the subsequent connection process.

[0014] 3. After the wire and copper busbar are connected, the threaded rod can be rotated to allow the two threaded sleeves to continue moving towards each other. During this process, the lug on the lower threaded sleeve will push the bent tongue, allowing the main pusher frame to move, which in turn pushes the pusher plate to move sideways, thereby driving the auxiliary pusher frame to move. This allows the gathering frame to move towards the fixed block, allowing a section of wire located between the wire support groove and the clamp to loosen. At the same time, the side-moving pusher plate will also cause the clamping post on the column plate to move sideways, pushing the loose wire towards the arc plate, so that the wire is clamped between the clamping post and the arc plate. At this time, under the pushing force of the clamping post, the arc plate will move sideways through the connecting frame and the slide to clamp the wire between the clamp and the clamp. This bends and clamps the wire to improve its tensile strength, so that the wire will not come loose from the U-shaped guide seat when subjected to external force, thus ensuring the stability of the conductive connection.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] This invention provides a technical solution: such as Figures 1-8The energy-saving power fitting shown includes a support plate 1. Multiple conductive seats 8 are linearly arrayed and fixedly installed at the front end of the support plate 1. Conductive posts 10 extend from the inner top surface of each conductive seat 8. A U-shaped guide seat 30 is fixedly installed at the upper center of each conductive seat 8. The conductive seats 8, conductive posts 10, and U-shaped guide seats 30 are all made of low-permeability aluminum alloy or similar materials to reduce eddy current losses, hysteresis losses, and contact resistance losses, thereby reducing power loss in transmission lines and making the power fitting of this invention more energy-efficient. A threaded rod 2 is rotatably installed through the center of the support plate 1. The threads at both ends of the threaded rod 2 are symmetrically arranged, allowing two threaded sleeves 17 to move towards each other. Threaded sleeves 17 are screwed onto both ends of the threaded rod 2. A bending and pressing frame 21 is fixedly installed at the front end of the threaded sleeve 17. When the two threaded sleeves 17 continue to move towards each other to bend and clamp the wire 5, the bending and pressing frame 21 on the two threaded sleeves 17 just abuts against the upper frame 4 and the lower frame 11, so that the upper frame 4 and the lower frame 11 maintain sufficient pressure for connection. A ring sleeve 22 is elastically installed on the opposite surface of the two threaded sleeves 17. The threaded rod 2 passes through the inside of the ring sleeve 22. A wire pressing block 31 is provided above the U-shaped guide seat 30. An upper frame 4 is fixedly installed on the upper end of the wire pressing block 31. The upper frame 4 serves to support the wire pressing block 31. The upper frame 4 is fixed to the ring sleeve 22 above. A top plate 7 is provided below the conductive seat 8. A download frame 11 is fixedly installed at the lower end of the plate 7. The download frame 11 serves to support the top plate 7. The top plate 7, the wire pressing block 31, and the support plate 1 are all made of insulating material to prevent conductivity. The download frame 11 is fixed to the lower ring 22. A wire support is provided at the rear end of the support plate 1. First, the conductive seat 8 is engaged with the copper busbar 6. At this time, the conductive post 10 on the conductive seat 8 is inserted into the wiring hole on the copper busbar 6. Then, the ends of multiple wires 5 are placed into the U-shaped guide seats 30 on multiple conductive seats 8 respectively. Then, the threaded rod 2 is rotated so that the two threaded sleeves 17 move towards each other under the action of the symmetrical arrangement of the threads at both ends of the threaded rod 2, thereby driving the two rings 22 to move towards each other. The upper ring 22 causes the wire clamping block 31 on the upper frame 4 to move downward, clamping the wire 5 into the U-shaped guide seat 30. The lower ring 22 causes the top plate 7 on the lower frame 11 to move upward, pressing against the copper busbar 6, thereby fixing the conductive seat 8 onto the copper busbar 6. This allows multiple wires 5 and the copper busbar 6 to be connected together to complete the conductive connection. The process can connect multiple wires 5 to the copper busbar 6 simultaneously, without having to tighten each bolt individually to connect each wire 5 to the copper busbar 6, effectively facilitating the conductive connection. In addition, during connection, the wires 5 can be directly connected to the copper busbar 6 without having to add copper lugs to the ends of the wires 5 before connection, further facilitating the conductive connection.

[0019] A push-clamp spring 3 is fixedly installed between the opposing surfaces of the ring sleeve 22 and the threaded sleeve 17. The push-clamp spring 3 pushes the ring sleeve 22. The threaded rod 2 passes through the inside of the push-clamp spring 3. Square rods 23 are fixedly installed on the upper and lower ends of the bearing plate 1 on the sides of the threaded rod 2. The square rods 23 guide the ring sleeve 22 and the threaded sleeve 17. The ring sleeve 22 and the threaded sleeve 17 are slidably installed on the outer surface of the square rods 23.

[0020] The wire support includes multiple fixing blocks 19 linearly arrayed and fixedly installed at the rear end of the support plate 1. The fixing blocks 19 serve as supports. Each fixing block 19 has a clamp 33 fixedly installed at its upper end. Each fixing block 19 has a slide 34 slidably installed through it. One end of the slide 34 is fixedly installed with a clamp 29. The slide 34 serves to guide the clamp 29. A gathering frame 9 is provided at the rear of the support plate 1. Multiple wire support grooves 28 are linearly arrayed and fixedly installed at the upper end of the gathering frame 9. The gathering frame 9 serves to support the wire support grooves 28. When the end of the wire 5 is placed in the U-shaped guide seat 30 on the conductive seat 8, the wire 5 can be pressed into the wire support groove 28 and clamped between the clamp 33 and the clamp 29 simultaneously, so that the end of the wire 5 is always located in the U-shaped guide seat 30 to wait for connection, thereby preventing the wire 5 from slipping during the subsequent connection process.

[0021] Guide shells 26 are fixedly installed at the rear ends of the two fixed blocks 19 on both sides. Guide cores 27 are slidably installed inside the guide shells 26. The guide cores 27 extend through the ends of the guide shells 26. The guide shells 26 and guide cores 27 serve to guide the gathering frame 9. The guide cores 27 are fixed to the gathering frame 9.

[0022] A guide seat 13 is elastically installed near the middle of the lower end of the bearing plate 1. A main pusher frame 12 is rotatably installed at the end of the guide seat 13. A pusher plate 20 is slidably installed between the lower parts of multiple fixing blocks 19. The end of the main pusher frame 12 is rotatably connected to the pusher plate 20. The upward movement of the guide seat 13 can drive the main pusher frame 12 to move, thereby pushing the pusher plate 20 to move laterally. A secondary pusher frame 24 is rotatably installed between the pusher plate 20 and the gathering frame 9. The lateral movement of the pusher plate 20 drives the secondary pusher frame 24 to move, so that the gathering frame 9 can move in the direction of the fixing block 19, allowing a section of wire 5 located between the wire support groove 28 and the clamp 33 to be relaxed. A bent tongue 14 extends from the side of the guide seat 13. A lug 18 is provided below the bent tongue 14. The lug 18 is fixed to the threaded sleeve 17 below. The lug 18 on the threaded sleeve 17 will push the bent tongue 14, causing the guide seat 13 to move upward.

[0023] A connecting frame 25 is fixedly installed at the other end of the slide 34. One end of the connecting frame 25 is pressed against the clamp 33, which can position the maximum distance between the clamp 33 and the clamp plate 29. An arc plate 36 is fixedly installed at the other end of the connecting frame 25. The connecting frame 25 serves to connect the arc plate 36. A wire clamping post 32 is provided on the side of the arc plate 36. A column plate 35 is fixedly installed at the lower end of the wire clamping post 32. The column plate 35 is fixed to the push plate 20. The push plate 20 will drive the wire clamping post 32 on the column plate 35 to move laterally, so as to push the slack wire 5 towards the direction of the arc plate 36, so that the wire 5 is clamped between the wire clamping post 32 and the arc plate 36. At this time, under the pushing force of the wire clamping post 32, the arc plate 36 will drive the clamp plate 29 to move laterally through the connecting frame 25 and the slide 34, so as to clamp the wire 5 between the clamp plate 29 and the clamp 33, thereby bending and clamping the wire 5.

[0024] A guide post 16 is fixedly installed at the lower end of the bearing plate 1 near the middle. A guide seat 13 is slidably installed on the outer surface of the guide post 16. The guide post 16 serves to guide the guide seat 13. A return spring 15 is wound around the outside of the guide post 16. The return spring 15 serves to reset the guide seat 13. The two ends of the return spring 15 are fixed to the bearing plate 1 and the guide seat 13 respectively.

[0025] Rubber pads 37 are provided on the opposite surfaces of the clamping plate 29 and the clamping seat 33, as well as on both sides of the inside of the wire support groove 28. The rubber pads 37 can increase the friction and the clamping force on the wire 5.

[0026] During the conductive connection, first, the conductive seat 8 is engaged with the copper busbar 6. At this time, the conductive post 10 on the conductive seat 8 is inserted into the wiring hole on the copper busbar 6. Then, the ends of multiple wires 5 are placed into the U-shaped guide seats 30 on multiple conductive seats 8 respectively, and the wires 5 are pressed into the wire support groove 28 and clamped between the clamp 33 and the clamp plate 29. Then, the threaded rod 2 is rotated, so that the two threaded sleeves 17 move towards each other due to the symmetrical arrangement of the threads at both ends of the threaded rod 2. This causes the two ring sleeves 22 to move towards each other, so that the upper ring sleeve 22 can drive the wire pressing block 31 on the upper frame 4 to move down, so as to clamp the wires 5 in the U-shaped guide seats 30. The lower ring sleeve 22 drives the top plate 7 on the lower frame 11 to move up, so as to press against the copper busbar 6, thereby fixing the conductive seat 8 to the copper busbar 6, so that multiple wires 5 and the copper busbar 6 are connected together to complete the conductive connection. Then, the threaded rod 2 is rotated again, so that the two threaded sleeves 17 continue to move towards each other. During this process, the lug 18 on the lower threaded sleeve 17 pushes the bent tongue 14, allowing the main pusher frame 12 to move, thereby pushing the pusher plate 20 to move laterally, which in turn drives the auxiliary pusher frame 24 to move, allowing the gathering frame 9 to move towards the direction of the fixing block 19, allowing the section of wire 5 located between the wire support groove 28 and the clamp 33 to loosen. At the same time, the laterally moving pusher plate 20 also causes the clamping post 32 on the column plate 35 to move laterally, so as to move the loosened wire 5 towards the arc plate 36. The conductor 5 is clamped between the clamping post 32 and the arc plate 36 by the direction of the movement. At this time, under the pushing force of the clamping post 32, the arc plate 36 will move the clamping plate 29 to the side through the connecting frame 25 and the slide 34, so as to clamp the conductor 5 between the clamping plate 29 and the clamping seat 33. This bends and clamps the conductor 5 to improve its tensile strength and prevents it from coming loose from the U-shaped guide seat 30 when it is pulled by external force, thus ensuring the stability of the conductive connection.
