A first limiting frame 20 is fixedly connected to one side of the connecting plate 14, and a second limiting frame 23 is slidably connected to one side of the connecting plate 14. The rear side of the second limiting frame 23 is inserted into the front side of the first limiting frame 20. A first traction plate 26 is inserted into the top of the first limiting frame 20, and a second traction plate 27 is hinged to the top of the first traction plate 26. A first sliding groove 15 matching the connecting plate 14 is formed on the outer wall of the terminal block housing 1, and the connecting plate 14 is slidably connected to the outer wall of the terminal block housing 1 through the first sliding groove 15. A screw hole 18 is formed on the other side of the connecting plate 14, and a screw thread is threaded into the inner side of the screw hole 18. One side of bolt 19 is attached to the outer wall of terminal block housing 1. A protective plate 4 is snapped into the bottom of the inner side of the limiting groove 2. The protective plate 4 covers the top of the connection port 13. During use, the connection port 13 facilitates the connection of the circuit. To facilitate the installation of the circuit, the user can first remove the second limiting frame 23 by plugging it in, and then connect the circuit connection points. After the connection is completed, the first limiting frame 20 and the second limiting frame 23 are connected as a whole by plugging it in. The height of the connecting plate 14 can be adjusted by the first sliding groove 15 so as to adjust according to the requirements of the circuit limiting point. After the adjustment is completed, the bolt 19 is turned and pressed against the outer wall of terminal block housing 1 to limit the position of the connecting plate 14. Thus, it can achieve the effect of conveniently limiting the outer wall of the circuit. While avoiding the circuit mess, it can also effectively prevent the circuit from being bent.
[0025] refer to Figure 1 A groove 16 is provided on the outer wall of the terminal block housing 1. A rubber pad 17 is fixedly connected to the inner side of the groove 16. The rubber pad 17 covers the inner side of the groove 16. One side of the bolt 19 is in contact with the other side of the rubber pad 17. Due to the presence of the rubber pad 17, which is made of rubber, it has good anti-slip ability and rubber elasticity. While improving the stability of the bolt 19 point under pressure, it can also make the connection plate 14 point more stable.
[0026] refer to Figures 1 to 3 A second sliding groove 22 matching the second limiting frame 23 is provided on one side of the connecting plate 14. The second limiting frame 23 is slidably connected to one side of the connecting plate 14 through the second sliding groove 22.

A positioning groove 21 matching the positioning block 24 is provided on the front side of the first limiting frame 20. The positioning block 24 is inserted into the inner side of the positioning groove 21. Due to the presence of the positioning block 24, the insertion of the positioning block 24 can effectively limit the position of the second limiting frame 23 to prevent the second limiting frame 23 from shifting. At the same time, it can also effectively improve the stability of the position limitation of the second limiting frame 23.
[0027] refer to Figure 4 A sealing ring 3 is fixedly connected to the bottom inner side of the limiting groove 2. The sealing ring 3 is five millimeters thick and is made of rubber material. The top of the sealing ring 3 corresponds to the bottom of the first limiting frame 20. Due to the presence of the sealing ring 3, when the bottom of the overall limiting frame structure is in contact with the top of the sealing ring 3, the sealing ring 3 can effectively seal the connection point of the overall limiting frame structure, and at the same time, it can also prevent the bottom of the overall limiting frame structure from being bumped.
[0028] refer to Figure 1 The top of the first limiting frame 20 and the second limiting frame 23 are both provided with slots 25. The bottom of the first traction plate 26 and the second traction plate 27 are both fixedly connected with plugs 28 that match the slots 25. The plugs 28 are inserted into the inside of the slots 25. Due to the presence of the plugs 28, the insertion of the plugs 28 can effectively limit the position of the first traction plate 26 and the second traction plate 27 to prevent them from shifting. Under the mutual traction of the first traction plate 26 and the second traction plate 27, the line connection can be made more accurate and safe.
[0029] refer to Figures 1 to 6 The top of the protective plate 4 is provided with a first slot 5, which extends into the interior of the terminal block housing 1. A second slot 6 is provided on the inner wall of the first slot 5, and a circular groove 7 is provided at the bottom inner side of the first slot 5. A first locking block 9 is engaged with the inner side of the first slot 5, and a second locking block 10 that matches the second slot 6 is fixedly connected to the outer side of the first locking block 9. The second locking block 10 is engaged with the inner side of the circular groove 7. Due to the presence of the first locking block 9, the second locking block 10 can be sent into the circular groove 7. The second locking block 10 is adjusted to an angle that is not corresponding to the second slot 6, thereby effectively engaging the protective plate 4. The protective plate 4 can seal the excess connection port 13. When the protective plate 4 needs to be removed, the second locking block 10 is adjusted to an angle corresponding to the second slot 6, and then the first locking block 9 can be pulled out directly, thereby exposing the excess connection port 13 so as to adjust the single or double cavity of the terminal block housing 1.
[0030] refer to Figures 1 to 6 A retaining spring 8 matching the second retaining block 10 is installed on the inner side of the circular groove 7. The bottom end of the second retaining block 10 is engaged with the top end of the retaining spring 8. The second retaining block 10 is engaged with the inner side of the circular groove 7 through the retaining spring 8. A sealing block 11 is fixedly connected to the top end of the first retaining block 9. The sealing block 11 covers the top end of the first retaining groove 5. A protrusion 12 is fixedly connected to the top end of the sealing block 11. The protrusion 12 has an arc-shaped corner. Due to the presence of the retaining spring 8, the engagement of the retaining spring 8 can further improve the stability of the engagement of the second retaining block 10. At the same time, it can also make the engagement of the protective plate 4 more stable, so as to avoid the displacement of the protective plate 4.
[0031] Operating principle and advantages: During use, the connection port 13 facilitates wiring. For easy wiring installation, the user can first disassemble the second limiting frame 23 using the plug-in principle, and then connect the wiring points. After connection, the first limiting frame 20 and the second limiting frame 23 are integrated using the plug-in principle. The first sliding groove 15 facilitates the adjustment of the height of the connecting plate 14 to meet the requirements of the wiring limiting points. After adjustment, tightening the bolt 19 and pressing it against the outer wall of the terminal block housing 1 limits the position of the connecting plate 14, thus achieving [the desired height]. This design facilitates the limiting of the outer wall of the wiring, preventing mess and bending. The presence of rubber pad 17, made of rubber, provides excellent anti-slip properties and elasticity, improving the stability of the bolt 19 under pressure and ensuring a more secure connection at point 14. The positioning block 24 effectively limits the second limiting frame 23, preventing displacement and enhancing its stability. The sealing ring... The presence of 3 allows the sealing ring 3 to effectively seal the connection point of the overall limiting frame structure when the bottom end of the overall limiting frame structure is in contact with the top end of the sealing ring 3. It also prevents the bottom end of the overall limiting frame structure from being bumped. Due to the presence of the insert block 28, its insertion effectively limits the positions of the first traction plate 26 and the second traction plate 27 to prevent displacement. Under the mutual traction of the first traction plate 26 and the second traction plate 27, the wiring connection becomes more accurate and secure. The presence of the first locking block 9 allows the second locking block 10 to be inserted into the circular groove 7. Adjusting the second locking block 10 to an angle that is not directly opposite to the second slot 6 allows for effective locking of the protective plate 4. The protective plate 4 can seal the excess connection port 13. When the protective plate 4 needs to be removed, adjust the second locking block 10 to an angle that corresponds to the second slot 6, and then pull out the first locking block 9 directly. This exposes the excess connection port 13, allowing for adjustment of the single or double cavity of the terminal block housing 1. Due to the presence of the retaining spring 8, the locking of the retaining spring 8 can further improve the stability of the locking of the second locking block 10, and also make the locking of the protective plate 4 more stable.
