Description

Technical Field

[0001] This utility model relates to the field of junction box technology, specifically to an electrical wiring junction box. Background Technology

[0002] Electrical junction boxes are indispensable connection and protection devices in modern building and industrial electrical systems. They are widely used in power distribution and signal transmission scenarios in residential, commercial buildings and industrial equipment. Their core function is to provide standardized connection ports and physical protection for different types of lines, ensuring that current and signals are transmitted stably and safely to terminal equipment.

[0003] However, existing junction boxes lack independent compartments, forcing high-voltage lines (such as mains power lines) and low-voltage lines (such as network communication lines and sensor signal lines) to coexist in the same enclosed space. This layout allows electromagnetic interference generated during high-voltage operation (such as power frequency magnetic fields and high-frequency harmonics) to directly intrude into the low-voltage system through spatial coupling or parasitic capacitance between lines, causing data transmission errors (such as network packet loss and snow in video surveillance images), signal attenuation, and even equipment malfunctions. More seriously, when the insulation of high-voltage and low-voltage lines is damaged due to long-term vibration, aging, or external pressure, direct contact between metal conductors can trigger a short circuit. The instantaneous high-temperature arc may burn out the lines or equipment, or even cause a fire, seriously threatening the safety and reliability of the electrical system. Therefore, we propose an electrical wiring junction box. Utility Model Content

[0004] The purpose of this utility model is to provide an electrical wiring junction box to solve the problems mentioned in the background art, such as electromagnetic interference causing signal transmission errors and insulation damage causing mixed short circuits due to the lack of isolation between strong and weak current lines in existing junction boxes.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an electrical wiring junction box, comprising: a box body and a box cover;

[0006] It also includes: several second partitions, which are located in the inner cavity of the box and are used to divide the inner cavity of the box;

[0007] The inner cavity of the box is symmetrically and fixedly connected with several limiting blocks. A connecting groove is provided on the side of the inner cavity of the box near the limiting block. A limiting component is provided in the inner cavity of the connecting groove. The limiting component is used to limit the position of the second partition in the inner cavity of the box. The second partition is slidably connected to the opposite surfaces of two adjacent limiting blocks.

[0008] The cable tray assembly is located in the lower part of the inner cavity of the box and is used to connect and connect electrical wires.

[0009] Several guide components are located in the middle of the box body and are used to guide the wires into the inner cavity of the box body.

[0010] The limiting component includes a housing that is fixedly connected to the inner cavity of the connecting groove. A slider is slidably connected to the inner cavity of the housing. A snap-fit ​​block is fixedly connected to the side of the slider near the second partition. A spring is provided in the inner cavity of the housing. The two sides of the spring are fixedly connected to the side of the slider away from the snap-fit ​​block and the side of the inner cavity of the housing away from the snap-fit ​​block, respectively. A guide rod is fixedly connected to the middle of the inner cavity of the housing. The guide rod is slidably connected to the slider and the snap-fit ​​block. The spring is wound around the outer surface of the guide rod.

[0011] The second partition has symmetrical operating grooves in the middle, and a limiting groove for use with the snap-fit ​​block is provided on the side of the second partition near the snap-fit ​​block. The second partition is made of flame-retardant reinforced PA66 plastic material.

[0012] The cable assembly includes a connecting block that is fixedly connected to the bottom wall of the inner cavity of the box. The connecting block is fixedly connected to several first partitions, and terminal screws are provided between two adjacent first partitions.

[0013] The first partition plate has symmetrically fixedly connected limit posts at its upper end, and the second partition plate has symmetrically opened second slots on the side near the wire assembly in the middle. The inner cavity of the second slot is engaged with the outer surface of the adjacent limit post.

[0014] The box body has a first connecting post fixedly connected to all four sides of the inner cavity, a first locking block fixedly connected to the upper end of the box body, an arc-shaped groove opened on all four sides of the upper part of the box cover, a second connecting post fixedly connected to all four sides of the inner cavity of the box cover, a number of screws threadedly connected to the box cover, the screws being threadedly connected to the adjacent second connecting post, and the screws being threadedly connected to the adjacent first connecting post, and a first locking groove opened at the lower part of the inner cavity of the box cover, the inner cavity of the first locking groove engaging with the first locking block.

Finally, by providing several connecting slots and installing limiting components within these slots, the position of the second partitions within the limiting block cavities can be restricted, improving the stability of the second partitions within the box cavity.

[0030] It also includes: several second partitions 5, the second partitions 5 being located in the inner cavity of the box body 1, the second partitions 5 being used to divide the inner cavity of the box body 1;

[0031] A number of limiting blocks 13 are symmetrically fixedly connected to the inner cavity of the box body 1. A connecting groove 14 is provided on the side of the inner cavity of the box body 1 near the limiting block 13. A limiting component 15 is provided in the inner cavity of the connecting groove 14. The limiting component 15 is used to limit the position of the second partition 5 in the inner cavity of the box body 1. The second partition 5 is slidably connected to the opposite surfaces of two adjacent limiting blocks 13.

[0032] Cable strip assembly 4 is located in the lower part of the inner cavity of the box 1. Cable strip assembly 4 is used to connect electrical wires.

[0033] Several guide components 3 are provided, which are located in the middle of the box body 1. The guide components 3 are used to guide the wires into the inner cavity of the box body 1.

[0034] By providing several second partitions 5, the inner cavity of the box 1 can be divided into multiple chambers, which can separate the high-voltage and low-voltage lines in the inner cavity of the box 1, preventing electromagnetic interference caused by the mixing of high-voltage and low-voltage lines without isolation, which could lead to signal transmission errors and short circuits caused by insulation damage. By symmetrically fixing several limiting blocks 13 in the inner cavity of the box 1, the second partitions 5 are slidably connected to the inner cavities of adjacent limiting blocks 13, which can limit the second partitions 5. By providing several connecting grooves 14, and setting limiting components 15 in the inner cavities of the connecting grooves 14, the position of the second partitions 5 in the inner cavities of the limiting blocks 13 can be limited by the limiting components 15, which can improve the stability of the second partitions 5 in the inner cavity of the box 1.

[0035] The limiting assembly 15 includes a housing 151 fixedly connected to the inner cavity of the connecting groove 14. A slider 153 is slidably connected to the inner cavity of the housing 151. A locking block 154 is fixedly connected to the side of the slider 153 near the second partition 5. A spring 152 is provided in the inner cavity of the housing 151. The two sides of the spring 152 are fixedly connected to the side of the slider 153 away from the locking block 154 and the side of the inner cavity of the housing 151 away from the locking block 154, respectively. A guide rod 155 is fixedly connected to the middle of the inner cavity of the housing 151. The guide rod 155 is slidably connected to the slider 153 and the locking block 154. The spring 152 is wound around the outer surface of the guide rod 155. The second partition 5 is symmetrically opened in the middle. The second partition 5 is provided with an operating groove 51. Each side of the second partition 5 near the snap-fit ​​block 154 is provided with a limiting groove 52 that cooperates with the snap-fit ​​block 154. The second partition 5 is made of flame-retardant reinforced PA66 plastic material.

The inner cavity of the second snap-fit ​​groove 53 is snapped with the outer surface of the adjacent limiting post 43.

[0036] When it is necessary to divide the inner cavity of the box body 1 to form multiple chambers, the second partition 5 is slid into the inner cavity of the corresponding limiting block 13. During the placement of the second partition 5, the second partition 5 applies a force to the locking block 154, causing the locking block 154 to slide away from the second partition 5. Then, the locking block 154 can be pushed into the inner cavity of the outer shell 151. When the locking block 154 slides, it will drive the slider 153 to move together, and then drive the slider... 153 applies a force to spring 152, causing spring 152 to contract. When the latching block 154 contacts the inner cavity of the limiting groove 52, the spring 152 will extend under its own elastic force, which will push the slider 153 to slide towards one side of the limiting groove 52, pushing the latching block 154 into the inner cavity of the limiting groove 52. Then, with the cooperation of the latching block 154 and the limiting groove 52, the position of the second partition 5 in the inner cavity of the limiting block 13 can be limited.

[0037] By providing an operating groove 51 in the middle of the second partition 5, it is convenient for workers to hold the second partition 5 through the operating groove 51. By connecting the connecting block 41 to the inner wall of the box 1, the position of the wire assembly 4 can be limited. Then, by providing several first partitions 42, several terminal screws 44 can be divided by the first partitions 42. Then, by cooperating with the first partitions 42 and the second partition 5, the sealing of the chamber can be improved. By providing several terminal screws 44, it is convenient to connect the wires. By fixing the limit post 43 to the upper end of the first partition 42, and by providing a second slot 53 in the lower part of the second partition 5, the position of the second partition 5 can be further limited by cooperating with the limit post 43 and the second slot 53, thereby improving the stability of the second partition 5 in the inner cavity of the box 1.

The upper part of the box cover 2 is provided with arc-shaped grooves 21 on all four sides. The inner cavity of the box cover 2 is fixedly connected to the second connecting post 23 on all four sides. The box cover 2 is threadedly connected to several screws 22. The screws 22 are threadedly connected to the adjacent second connecting post 23 and the adjacent first connecting post 12. The lower part of the inner cavity of the box cover 2 is provided with the first locking groove 24. The inner cavity of the first locking groove 24 is engaged with the first locking block 11. The guide component 3 includes a first connecting tube 31 fixedly connected to the box body 1. The outer surface of the first connecting tube 31 away from the box body 1 is threadedly connected to the second connecting tube 33. The inner cavity of the second connecting tube 33 is fixedly connected to the rubber block 34. The inner cavity of the first connecting tube 31 away from the rubber block 34 is engaged with the dustproof locking block 32.

[0040] The first connecting tube 31 is fixedly connected to the box body 1, and the inner cavity of the first connecting tube 31 communicates with the inner cavity of the box body 1, thus facilitating the transmission of the wire through the inner cavity of the first connecting tube 31 into the inner cavity of the box body 1, where it is then connected to the terminal screw 44. A dustproof block 32 is engaged with the inner cavity of the first connecting tube 31 on the side away from the second connecting tube 33, thereby sealing the inner cavity of the first connecting tube 31 and preventing external dust from drifting into the inner cavity of the box body 1 when the wire is not being passed through it, thus affecting the normal operation of the cable assembly 4. The dustproof block 32 engaged in the inner cavity of the first connecting tube 31 provides dust and moisture protection to the inner cavity of the box body 1. The second connecting tube 33 is connected to the first connecting tube 31 by screws... The second connecting tube 33 is connected to the first connecting tube 31 by a threaded connection. A rubber block 34 is fixedly connected inside the second connecting tube 33. When the wire passes through the inner cavity of the second connecting tube 33, the elasticity of the rubber block 34 can be used to make the inner cavity of the rubber block 34 fit tightly against the outer surface of the wire. This prevents dust and moisture from entering the inner cavity of the box 1 through the gap between the inner cavity of the rubber block 34 and the outer surface of the wire, and causing a short circuit in the inner cavity of the box 1. The first locking block 11 is engaged with the inner cavity of the first locking groove 24 to improve the sealing of the entire device when the box cover 2 and the box 1 are closed. The second connecting post 23 and the first connecting post 12 are provided to facilitate the use of the screw 22 to fix the position of the box cover 2 and the box 1, preventing the box cover 2 from separating from the box 1.
