Description

Technical Field

[0001] This utility model relates to the field of wiring equipment technology, and in particular to a junction box for building electrical systems. Background Technology

[0002] Building electrical junction boxes are widely used in building electrical systems to protect electrical wiring and ensure circuit safety. Traditional junction box designs typically include fixed terminals and screw fasteners to secure the wires to the terminals. Traditional wiring methods usually require winding the copper wire once to increase the contact area, and then using a tool to tighten the screws to secure the wire.

[0003] The above process not only requires precise operation, but also the use of additional tools for tightening. The operation is cumbersome and prone to errors, especially in confined spaces or poor working conditions. In addition, traditional junction boxes often require tools for disassembly and repair, which makes the repair process more complicated and time-consuming. When it is necessary to inspect or repair the electrical system, the junction box usually needs to be disassembled with tools such as screwdrivers, and the operation is inconvenient after disassembly, which increases the workload of workers. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a junction box for building electrical systems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a junction box for building electrical systems, comprising a junction box body, a cover hinged to the back of the junction box body, L-shaped plates fixedly connected to both sides of the inner wall of the cover, and fixed seats fixedly connected to both sides of the inner wall of the junction box body. The top and interior of the fixed seats are respectively provided with a placement groove and a movable groove. An installation component capable of fixing the L-shaped plates is provided inside the movable groove. A plurality of terminal blocks are fixedly installed on the inner bottom surface of the junction box body. A plurality of conductive terminals are fixedly connected to the top of each terminal block. A threaded hole is provided on the top of each conductive terminal, and a fastening component is provided inside the threaded hole.

[0006] The junction box body serves as the main frame, supporting conductive terminals, terminal blocks, and mounting components, providing space for wire connection and protection. A hinged cover is mounted on the back, allowing for quick opening and closing via a mounting bracket and mounting components. L-shaped plates are fixed to both sides inside the cover, acting as locking fulcrums. These plates, in conjunction with a fixing rod, secure and unlock the cover. When closed, the cover is embedded in the mounting slot of the fixing bracket, and the fixing rod is inserted into its hole to lock it in place. The fixing bracket is fixed to both sides of the inner wall of the junction box body, providing the mounting reference for the locking structure. The terminal blocks secure the conductive terminals, providing electrical connection and mechanical support. Multiple terminal positions are provided according to the number of cables, supporting multi-wire parallel connection.

[0007] As a further description of the above technical solution:

[0008] The mounting assembly includes a fixed rod that is slidably mounted inside the movable slot, one end of which extends through to the outside of the junction box body and is fixedly connected to a pull button.

[0009] The fixing rod moves laterally to insert or remove the L-shaped plate, completing the mechanical locking of the lid.

[0010] As a further description of the above technical solution:

[0011] A push ring is fixedly connected to the outer wall of the fixed rod and inside the movable groove, and a spring is fixedly connected to one side of the push ring.

[0012] One end of the spring is fixedly connected to the inner wall of the movable groove. When the pull button is pulled, the fixing rod is pulled out from the hole in the L-shaped plate and the lock is released. When the spring returns to its original position, it pushes the fixing rod to re-lock.

[0013] As a further description of the above technical solution:

[0014] The L-shaped plate is movably placed inside the placement slot and interlocked with the fixing rod.

[0015] As a further description of the above technical solution:

[0016] The fastening assembly includes a fastening rod threaded into a threaded hole, and a knob is fixedly connected to the top of the fastening rod.

[0017] The fastening rod rotates and rises through the threaded hole, causing the copper wire to automatically wind and tighten. When the knob is rotated, the fastening rod moves down along the threaded hole, and the outer thread guides the copper wire to spirally wind.

[0018] As a further description of the above technical solution:

[0019] A wiring block is fixedly connected to the outer wall of the fastening rod, and a wiring hole is provided on one side of the wiring block.

[0020] The connector block is fixed to the outer wall of the fastening rod, and the wiring hole guides the copper wire through and pre-positions it.

This avoids the tedious steps of traditional manual winding of copper wire, simplifies wiring operations, and saves time. At the same time, automatic winding ensures that the copper wire is wound evenly, improving the quality and stability of the connection. Furthermore, the increased contact area of ​​the copper wire during rotation optimizes the stability of the electrical connection.

[0029] 2. Compared with existing technologies, this building electrical junction box, through the combined use of structures such as a fixing base, an L-shaped plate, a fixing base, and mounting components, utilizes a pull button and a fixing rod design to make the opening and closing process of the cover box very simple. Users do not need to use tools; they only need to pull the pull button to unlock the L-shaped plate, facilitating maintenance operations.

[0038] Reference Figure 1-5 This utility model provides a junction box for building electrical systems, comprising a junction box body 1, a cover 2 hinged to the back of the junction box body 1, L-shaped plates 3 fixedly connected to both sides of the inner wall of the cover 2, and fixing seats 4 fixedly connected to both sides of the inner wall of the junction box body 1. The top and interior of the fixing seats 4 are respectively provided with a placement groove 5 and a movable groove 6. The movable groove 6 contains an installation component for fixing the L-shaped plates 3. Several terminal blocks 7 are fixedly installed on the inner bottom surface of the junction box body 1. Several conductive terminals 8 are fixedly connected to the top of the terminal blocks 7. The top of the conductive terminals 8 has threaded holes 9, and fastening components are provided inside the threaded holes 9. The junction box body 1 serves as the main frame, supporting the conductive terminals 8, terminal blocks 7, and installation components, providing space for wire connection and protection. The cover 2 is hinged to the back, and the fixing seats 4 and installation components enable the quick opening and closing of the cover 2. The L-shaped plates 3 are fixed to the cover. Inside the box 2, on both sides, serving as locking fulcrums, cooperate with the fixing rod 10 to fix and unlock the box 2. When closed, it is embedded in the placement groove 5 of the fixing seat 4, and the fixing rod 10 is inserted into its hole to complete the locking. The fixing seat 4 is fixed on both sides of the inner wall of the junction box body 1, providing the installation reference for the locking structure. The junction box 7 fixes the conductive terminal 8, providing electrical connection and mechanical support. Multiple terminal positions are set according to the number of cables, supporting multi-line parallel connection. Through the cooperation of the junction box 7, conductive terminal 8, threaded hole 9 and fastening component, the copper wire can be automatically wound on the outer wall of the fastening rod 14 by rotating the knob 15, avoiding the tedious steps of traditional manual winding of copper wire, simplifying the wiring operation and saving time. At the same time, automatic winding ensures that the copper wire is wound evenly, improving the quality and stability of the connection. In addition, the increased contact area of ​​the copper wire during rotation optimizes the stability of the electrical connection.

[0039] The mounting assembly includes a fixed rod 10 that is slidably installed inside the movable slot 6. One end of the fixed rod 10 extends through to the outside of the junction box body 1 and is fixedly connected to a pull button 11. The fixed rod 10 moves laterally to insert into or remove from the L-shaped plate 3, completing the mechanical locking of the cover box 2. A push ring 12 is fixedly connected to the outer wall of the fixed rod 10 and inside the movable slot 6. A spring 13 is fixedly connected to one side of the push ring 12. One end of the spring 13 is fixedly connected to the inner wall of the movable slot 6. When the pull button 11 is pulled, the fixed rod 10 is pulled out from the hole in the L-shaped plate 3, releasing the lock. When the spring 13 returns to its original position, it pushes the fixed rod 10 to re-engage. The L-shaped plate 3 is movably placed inside the placement slot 5 and engages with the fixed rod 10.

[0040] The fastening assembly includes a fastening rod 14 threaded into a threaded hole 9. A knob 15 is fixedly connected to the top of the fastening rod 14. The fastening rod 14 rotates and rises through the threaded hole 9, causing the copper wire to automatically wind and tighten. When the knob 15 is rotated, the fastening rod 14 moves down along the threaded hole 9, and the outer wall thread guides the copper wire to spirally wind. A connector block 16 is fixedly connected to the outer wall of the fastening rod 14. A connector hole 17 is opened on one side of the connector block 16. The connector block 16 is fixed to the outer wall of the fastening rod 14. The connector hole 17 guides the copper wire to pass through and pre-position it. A fastening screw 18 is threadedly connected to the front of the connector block 16. One end of the fastening screw 18 is threaded through the interior of the connector hole 17. The fastening screw 18 pre-tightens the copper wire to prevent the copper wire from slipping when the connector block 16 rotates. A semi-circular disc 19 is fixedly connected to the outer wall of the fastening rod 14. When the semi-circular disc 19 moves down with the fastening rod 14, it squeezes the copper wire to ensure that the wound cable is tightly attached and fixed under constant pressure.

[0041] Working principle: First, install the device in a suitable position. When it needs to be opened for maintenance, pull the button 11 to move the fixing rod 10, allowing it to be pulled out from the hole in the L-shaped plate 3, thus releasing the L-shaped plate 3 from its fixation. Then, the cover box 2 can be rotated to facilitate maintenance of the inside of the junction box body 1. When it needs to be closed, simply pull the button 11 to push the spring 13 on the fixing rod 10, causing it to rotate so that the L-shaped plate 3 aligns with the placement slot 5 on the fixing seat 4. Then, release the button 11. Under the reaction force of the spring 13, the spring 13 pushes the push ring 12, moving the fixing rod 10 to reset and engage with the L-shaped plate 3, thus completing the fixation. This makes it convenient to use and greatly improves the ease of maintenance.

[0042] When wiring is required, simply pass the copper wire inside the wire through the wiring hole 17, then rotate the fastening screw 18 to rotate and move it, squeezing the copper wire. Then, place the copper wire around the fastening rod 14 under the semi-circular disc 19. Then, manually rotate the knob 15 to rotate it and drive the copper wire to rotate, so that the copper wire is wound around the outer wall of the fastening rod 14 and wound through the threaded hole 9. At the same time, the semi-circular disc 19 presses down on the copper wire, so that the copper wire will be automatically wound and compressed during the rotation, ensuring a tightness effect. This solves the problem of difficult manual winding, simplifies the wiring operation, saves wiring time, and because the copper wire is automatically wound and tightly contacted during the rotation, it not only increases the contact area but also reduces the problem of poor contact caused by improper human operation, thereby improving the stability and safety of the electrical connection.
