Description
Technical Field
[0001] This utility model relates to the field of connector technology, specifically to a quick connector for power distribution lines. Background Technology
[0002] In power systems, the connection of distribution lines is a key link to ensure stable power transmission. Currently, after the two wires are connected, they are often only wrapped with a single insulating tape. When the wires are accidentally pulled, this connection method often cannot effectively distribute the tension, resulting in excessive stress on the wire core, which can easily cause the line to loosen or even break, seriously affecting the stability and safety of the distribution line. To address this, we propose a quick connector for distribution lines. Utility Model Content
[0003] The purpose of this invention is to provide a quick connector for power distribution lines, which solves the problems in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a quick connector for power distribution lines, comprising a junction box one and a junction box two, a connecting component being provided between one side of the junction box one and the junction box two, a fixing component being provided inside the junction box one and the junction box two, a limiting groove being provided on the inner wall of the junction box one and the junction box two, a conductive plate being fixedly installed on the inner wall of the junction box one and the junction box two near one side, a conductive block being fixedly installed on one side of the conductive plate, a conduit being provided communicating with the other side of the junction box one and the junction box two, an air cushion being fixedly installed on the inner wall of the conduit, and a sealing gasket being fixedly installed on one side of the junction box one and the junction box two;
[0005] The fixing assembly includes a clamp plate one and a clamp plate two. The top end of the clamp plate one and the bottom end of the clamp plate two are rotatably connected to screws via bearing seats. The two screws are threadedly connected to threaded holes at the top and bottom ends of the junction box one, respectively. A knob is fixedly installed at one end of each screw. A waterproof cloth is fixedly connected between the top end of the clamp plate one and the bottom end of the clamp plate two and the top and bottom ends of the inner wall of the junction box one, respectively. The waterproof cloth is placed on the outer wall of the screws. The clamp plate one and the clamp plate two are slidably connected to the inner wall of the junction box one.
[0006] Preferably, limit sliders are fixedly installed on the outer walls of both clamping plate one and clamping plate two. The limit sliders are slidably connected to the limit grooves. By setting the limit sliders and the limit grooves, clamping plate one and clamping plate two can be limited to ensure their stability during use.
[0007] Preferably, the junction box has drainage holes at both the top and bottom, with plugs tightly inserted into the drainage holes. Clamping pads are fixedly installed on the inner sides of clamping plates one and two. The clamping pads are made of PVC soft rubber. By setting drainage holes, water entering the waterproof cloth can be drained out. By setting clamping pads, the friction between clamping plates one and two and the wires can be increased, thereby improving clamping stability.
[0008] Preferably, the connecting assembly includes a first connecting plate and a second connecting plate, which are respectively fixedly installed on the outer walls of a first junction box and a second junction box. A connecting post is fixedly installed on one side of the second connecting plate. A connecting hole is provided on the first connecting plate, and the connecting post movably passes through the connecting hole. A shrinkage groove is provided on the outer wall of the first junction box, and a retaining plate is inserted into the shrinkage groove. A retaining slot is provided on the outer wall of the connecting post, and the retaining plate is engaged in the retaining slot. A spring is fixedly connected between one end of the retaining plate and the inner wall of the shrinkage groove.
[0009] Preferably, there are two connecting posts and two connecting holes, and the connecting posts and connecting holes are adapted to each other. The card plate and the card slot are adapted to each other. By setting the card plate, the card plate can be inserted into the card slot, thereby limiting and fixing the connecting post.
[0010] Preferably, a limiting rod is fixedly installed on the inner wall of the shrinkage groove, and a rod groove is opened at one end of the clamping plate. The limiting rod is inserted into the rod groove, and the spring surrounds the outer wall of the limiting rod. By setting the limiting rod, the spring can be limited, ensuring the stability of the spring during compression.
[0011] This utility model provides a quick-connector for power distribution lines. This quick-connector for power distribution lines has the following advantages:
[0012] (1) The quick connector for the power distribution line can clamp two wires in junction box one and junction box two respectively, and then connect junction box one and junction box two. When the two wires are pulled after the connection is completed, the clamps in junction box one and junction box two will fix and tighten the two wires, greatly reducing the stress on the wire cores of the two wires, thereby improving the stability and firmness of the connection between the two wires. This solves the problem that when the two wires are accidentally pulled after the connection, the traditional connection method often cannot effectively disperse the pulling force, resulting in excessive stress on the wire cores, which can easily cause the line to loosen or even break, seriously affecting the stability and safety of the power distribution line.
[0013] (2) The quick connector for the power distribution line can greatly improve the sealing and waterproof performance of junction box 1 and junction box 2 after connecting two wires by setting air cushion, waterproof cloth and sealing gasket, so as to avoid the phenomenon of wires getting damp, leakage and short circuit.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0024] like Figure 1-6 As shown, this utility model provides a technical solution: a quick connector for power distribution lines, including a junction box 1 and a junction box 2. A connecting component is provided between one side of the junction box 1 and the junction box 2. A fixing component is provided inside the junction box 1 and the junction box 2. A limit groove 3 is provided on the inner wall of the junction box 1 and the junction box 2. A conductive plate 14 is fixedly installed on the inner wall of the junction box 1 and the junction box 2 near one side. A conductive block 16 is fixedly installed on one side of the conductive plate 14. A wire conduit 9 is connected to the other side of the junction box 1 and the junction box 2. An air cushion 10 is fixedly installed on the inner wall of the wire conduit 9. A sealing gasket 28 is fixedly installed on one side of the junction box 1 and the junction box 2.
[0025] The connecting assembly includes a first connecting plate 17 and a second connecting plate 18. The first connecting plate 17 and the second connecting plate 18 are respectively fixedly installed on the outer walls of junction box 1 and junction box 2. A connecting post 19 is fixedly installed on one side of the second connecting plate 18. A connecting hole 20 is opened on the first connecting plate 17. The connecting post 19 movably passes through the connecting hole 20. A shrinkage groove 22 is opened on the outer wall of junction box 1. A retaining plate 21 is inserted into the shrinkage groove 22. A retaining slot 26 is opened on the outer wall of the connecting post 19. The retaining plate 21 is engaged in the retaining slot 26. A spring 25 is fixedly connected between one end of the retaining plate 21 and the inner wall of the shrinkage groove 22.
[0026] The fixing assembly includes clamp 4 and clamp 6. The top of clamp 4 and the bottom of clamp 6 are rotatably connected to screws 5 through bearing seats. The two screws 5 are threadedly connected to the threaded holes at the top and bottom of junction box 1, respectively. A knob 11 is fixedly installed at one end of each screw 5. A waterproof cloth 8 is fixedly connected between the top of clamp 4 and the bottom of clamp 6 and the top and bottom of the inner wall of junction box 1, respectively. The waterproof cloth 8 is placed on the outer wall of the screws 5. Clamp 4 and clamp 6 are slidably connected to the inner wall of junction box 1.
[0027] Specifically, in the above technical solution, when using the quick connector for the power distribution line, junction box 1 and junction box 2 are respectively passed through conduit 9 through which the two wires to be connected are threaded, so that the core of one end of the two wires is connected to the conductive plate 14. Then, the knob 11 on junction box 1 and junction box 2 is rotated, so that the knob 11 drives the screw 5 to rotate, so that the two screws 5 respectively drive clamping plate 4 and clamping plate 6 to move closer to each other, so that clamping plate 4 and clamping plate 6 clamp the wires, thereby making junction box 1... Junction box 1 and junction box 2 are fixed to the two wires respectively. Then, junction box 1 and junction box 2 are connected so that the conductive blocks 16 on the conductive plates 14 in junction box 1 and junction box 2 come into contact with each other. Then, the locking plate 21 is pressed and retracted into the shrink groove 22, which compresses the spring 25. Then, the connecting post 19 moves through the connecting hole 20. At this time, the locking plate 21 is released, and the locking plate 21 will be locked into the slot 26 under the restoring force of the spring 25, thus limiting and fixing the connecting post 19. The connection between junction box 1 and junction box 2 is completed, thereby completing the wiring operation of the two wires. Through the above structure, junction box 1 and junction box 2 can clamp the two wires respectively. Then, junction box 1 and junction box 2 are connected. When the two wires are pulled after the wiring is completed, the clamping plates 4 and 6 in junction box 1 and junction box 2 will fix and tighten the two wires, greatly reducing the stress on the wire cores, thereby improving the stability and firmness of the connection between the two wires. This solves the problem that traditional wiring methods often cannot effectively distribute the pulling force when the wires are accidentally pulled after wiring, resulting in excessive stress on the wire cores, which can easily cause the line to loosen or even break, seriously affecting the stability and safety of the power distribution line. By setting air cushion 10, waterproof cloth 8 and sealing gasket 28, the sealing and waterproof performance of junction box 1 and junction box 2 after wiring the two wires can be greatly improved, avoiding the phenomenon of wires getting damp, leakage and short circuit.
[0028] Furthermore, limit sliders 15 are fixedly installed on the outer walls of both clamp 4 and clamp 6, and the limit sliders 15 are slidably connected to the limit grooves 3.
[0029] By setting the limiting slider 15 and the limiting groove 3, the clamping plate 4 and the clamping plate 6 can be limited to ensure the stability of the clamping plate 4 and the clamping plate 6 during use.
[0030] Furthermore, both the top and bottom of junction box 1 are provided with drainage holes 12, and plugs 13 are tightly inserted into the drainage holes 12. Clips 7 are fixedly installed on the inner sides of clamps 4 and clamps 6. The material of clips 7 is PVC soft rubber.
[0031] The system includes a drain hole 12 to allow water to drain from the waterproof cloth 8, and a clamping pad 7 to increase friction between the clamping plates 4 and 6 and the wire, thereby improving clamping stability.
[0032] Furthermore, there are two connecting posts 19 and two connecting holes 20, and the connecting posts 19 and the connecting holes 20 are compatible, and the card plate 21 is compatible with the card slot 26.
[0033] The connecting post 19 is fixed by setting a locking plate 21 so that it can be inserted into the locking slot 26.
[0034] Furthermore, a limiting rod 23 is fixedly installed on the inner wall of the shrinkage groove 22, and a rod groove 24 is opened at one end of the clamping plate 21. The limiting rod 23 is inserted into the rod groove 24, and the spring 25 surrounds the outer wall of the limiting rod 23.
[0035] The limiting rod 23 can limit the spring 25 and ensure the stability of the spring 25 during compression.
