Technical Field

[0001] This utility model relates to the field of junction box technology, specifically to a junction box equipped with a dustproof component. Background Technology

[0002] Junction boxes are commonly used devices in power systems. They are used to connect electrical wires. For example, a junction box can connect a main line to multiple branch lines, enabling the transmission of power from the main line to the terminal equipment of each branch line. A junction box generally consists of several parts, including a base box, a cover, a cable inlet, a wiring mechanism, connecting wires, and connectors. Junction boxes are typically designed with dustproof and insulation properties in mind to prevent electric shock and leakage, thus protecting personal safety.

[0003] Currently, junction boxes typically have multiple openings. After the cable passes through the inlet hole, it is fixed inside the junction box by bolts and other connectors. Because the working environment of junction boxes is relatively complex, and they are often in a humid and dusty environment, dust and moisture entering the junction box can cause discharge at the terminals. In severe cases, the internal circuit will short-circuit, affecting the use of the circuit and even damaging the motor, posing a great safety hazard. In addition, existing junction boxes require tools to open them when replacing, inspecting and maintaining cables, which is time-consuming, laborious and difficult to disassemble.

[0020] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Please see the appendix Figures 1-5 This application provides the following technical solutions.

[0022] A junction box with dustproof components includes a junction box body 1, a fixing member 2 provided at the bottom of the side wall of the junction box body 1, a wiring terminal 7 provided inside the junction box body 1, a cover 3 rotatably connected to the top of the junction box body 1, and several through holes 4 provided on both sides of the junction box body 1; the cover 3 includes a cover body 31, two shrink plates 32 fixedly connected to the side wall of the cover body 31, several shrink grooves 33 provided on opposite sides of the two shrink plates 32, wire clamping plates 34 slidably connected to the inner walls of the shrink grooves 33, two limiting grooves 36 provided on one side of the shrink grooves 33, springs 37 provided inside the two limiting grooves 36, and a first groove provided on the side of the wire clamping plates 34 facing out of the shrink grooves 33. Two sliding rods 35 are fixedly connected to one side of the junction box body 1 located within the shrinkage groove 33. The end of the sliding rod 35 away from the clamping plate 34 is inserted into the limiting groove 36. The end of the sliding rod 35 within the limiting groove 36 is fixedly connected to the spring 37. Several clamping plates 6 are provided on the bottom surface of the inner wall of the junction box body 1. A second groove is provided on the top of the clamping plates 6. The diameter of the second groove is equal to the diameter of the first groove and the wire hole 4. The clamping plates 6 correspond to the wire holes 4 and the clamping plates 34. A gap is provided between the clamping plates 6 and the inner wall of the junction box body 1. The width of the gap is the same as the thickness of the clamping plate 34. Baffles 15 are provided on both sides of the clamping plates 6. One side of the baffle 15 is in contact with the inner wall of the junction box body 1.

[0023] It should be noted that during use, the operator connects the device to the desired location by passing the fixing screw through the fixing piece 2. After fixing, the operator inserts the wire to be connected through the wire holes 4 on both sides of the junction box body 1. The wire passes through the second groove on the top of the clamping plate 2 6 and is connected through the terminal 7. After installation, the operator rotates and closes the box cover body 31, so that the clamping plate 1 34 is inserted into the storage groove formed between the baffle 15 and the clamping plate 2 6. For the wire holes 4 where no wire is inserted, the clamping plate 1 34 directly blocks them. When the clamping plate 1 34 contacts the wire and is squeezed, it retracts into the shrinkage groove 1 33. The sliding rod 1 35 is inserted into the limiting groove 1 36 and squeezes the spring 1 37 to retract it. The first groove on the clamping plate 1 34 and the second groove on the clamping plate 2 6 clamp the wire tightly, reducing the gap, until the box cover body 31 and the junction box body 1 are in contact. At the same time, the baffle 15 is set to be in contact with the clamping plate 1 34 to completely seal it.

[0024] A locking block 38 is fixedly connected to the side wall of the main body 31 of the junction box. The locking block 38 has locking slots 39 on both sides. A slot 5 is provided on the top of the main body 1 of the junction box. A second contraction groove 8 is provided on the inner wall of the slot 5. A sliding groove 14 is provided through the inner wall of the slot 5, and the sliding groove 14 communicates with the second contraction groove 8. Two limiting grooves 12 are provided on one side of the inner wall of the second contraction groove 8. A buckle 10 is slidably connected inside the second contraction groove 8. A lever 9 is fixedly connected to one side of the buckle 10, and the lever 9 is slidably connected to the inner wall of the sliding groove 14. Two sliding rods 11 are fixedly connected to the other side of the buckle 10. The outer wall of the sliding rod 11 is slidably connected to the limiting groove 12. A spring 13 is fixedly connected to the end of the sliding rod 11 away from the buckle 10, and the spring 13 is located inside the limiting groove 12.

[0025] It should be noted that when the box cover body 31 is rotated and closed, the locking block 38 presses the buckle 10, causing it to retract into the shrinkage groove 2 8, and the sliding rod 2 11 is retracted into the limiting groove 2 12. At the same time, the spring 2 13 is pressed, causing it to contract and generate elastic potential energy until the box cover body 31 is attached to the top of the junction box body 1. At this time, the spring 2 13 releases elastic potential energy to push the buckle 10 to reset and insert into the slot 39. When the staff needs to inspect the wires, the operator presses the two levers 9 along the sliding groove 14 to both sides, causing the buckle 10 to slide along the inner wall of the shrinkage groove 2 8 until it is disengaged from the slot 39. At this time, the staff can rotate and pull the box cover body 31 to open the device for inspection.

[0026] In use, the operator connects the device to the desired location by passing the fixing screw through the fixing piece 2. After fixing, the operator inserts the wire to be connected through the wire holes 4 on both sides of the junction box body 1. The wire passes through the second groove on the top of the clamping plate 2 6 and is connected through the terminal 7. After installation, the operator rotates and closes the box cover body 31, so that the clamping plate 1 34 is inserted into the storage groove formed between the baffle 15 and the clamping plate 2 6. For the wire holes 4 where no wire is inserted, the clamping plate 1 34 directly blocks them. When the clamping plate 1 34 comes into contact with the wire and is squeezed, it retracts into the shrinkage groove 1 33. The sliding rod 1 35 inserts into the limiting groove 1 36 and squeezes the spring 1 37 to retract it, so that the first groove on the clamping plate 1 34 and the second groove on the clamping plate 2 6 clamp the wire. The gap is reduced until the cover body 31 is in contact with the junction box body 1. At the same time, the baffle 15 is set to fit against the clamping plate 34 to completely seal it. When the cover body 31 is rotated to close, the locking block 38 presses the buckle 10, causing it to retract into the shrinkage groove 8. The sliding rod 11 is then put into the limiting groove 12, while the spring 13 is compressed to generate elastic potential energy until the cover body 31 is in contact with the top of the junction box body 1. At this time, the spring 13 releases its elastic potential energy and pushes the buckle 10 to reset and insert into the slot 39. When the staff needs to inspect the wires, the operator presses the two levers 9 along the sliding groove 14 to both sides, causing the buckle 10 to slide along the inner wall of the shrinkage groove 8 until it is disengaged from the slot 39. At this time, the staff can rotate and pull the cover body 31 to open the device for inspection.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
