Description

Technical Field

[0001] This utility model relates to the electrical field, and in particular to an electrical installation wiring device. Background Technology

[0002] An existing patent (publication number: CN220822605U) discloses a wiring device for building electrical installation, including a main body, a collar fixedly connected to one side of the main body, an operating opening fixedly connected to one side of the main body, a fixing block fixedly connected to one side of the main body, and a nut fixedly connected to one side of the fixing block. However, the "operating opening on one side of the main body" in this device is an open opening that easily leads to the accumulation of dust inside. The corrosive particles in the dust can erode the insulating material, causing a decrease in insulation performance, leading to short circuits or leakage, reducing the durability of the device, and posing a drawback. Summary of the Invention

[0003] This utility model addresses the aforementioned shortcomings of existing technologies by providing an electrical installation wiring device that is dustproof, preventing external dust from entering and corroding the insulating material, improving the insulation performance and durability of the device, reducing the risk of short circuits and leakage, while also providing stable clamping to prevent loosening at the wiring points, ensuring safe and stable electrical wiring, and facilitating easy disassembly and assembly for cable inspection or replacement, thereby improving the efficiency of electrical installation work.

[0004] The objective of this utility model is achieved through the following technical solution: An electrical installation wiring device includes a nut, a dustproof ring, a junction box, a locking bar, a control half-ring, a bidirectional lead screw, and a clamping plate. The junction box has a wiring groove in the middle, and mounting half-shells at both ends. The outer side of the mounting half-shell has a threaded half-shell, and the inner side of the mounting half-shell has a fixing groove. The fixing groove is adapted to the cable and connects to the cable. The cable is connected to the inside of the dustproof ring, and the nut is connected to the outside of the dustproof ring. The nut is threadedly connected to the threaded half-shell. The nut has locking grooves on both sides, and the mounting half-shell has a storage groove. The storage groove and locking groove are adapted to the locking bar. The outer end of the locking bar is connected to the locking groove, and the inner end of the locking bar is connected to a spring. The spring is connected to the mounting half-shell.

[0005] The present invention relates to an external connection control half-ring for the mounting half-shell. The control half-ring has a lever, the mounting half-shell has a sliding hole, and the locking bar has a lever groove. The lever groove and the sliding hole are adapted to the lever. The lever passes through the sliding hole and is connected to the lever groove. The control half-ring is divided into an upper control half-ring and a lower control half-ring. The upper control half-ring is connected to the lower control half-ring. The lower control half-ring has protruding rods on both sides, and the upper control half-ring has protruding rod holes on both sides. The protruding rods are adapted to the protruding rod holes and pass through the protruding rod holes.

[0006] The junction box of this utility model is divided into an upper junction box and a lower junction box. The upper junction box is connected to the lower junction box. The upper junction box has multiple docking rods, and the lower junction box has multiple docking slots. The docking rods are adapted to the docking slots and are connected to the docking slots. The lower junction box is connected to a clamping plate. The clamping plate is connected to the outside of the rubber pad, and the inside of the rubber pad is connected to the cable. Beneficial effects

[0007] This utility model's junction box adopts an upper and lower junction box docking structure. With the precise engagement of the docking plug and the docking slot, the sealing of the wiring slot area is ensured. The threaded half-shells at both ends of the junction box are fixedly connected by threads and nuts, increasing the stability and tightness of the connection between the upper and lower junction boxes, preventing them from separating and creating gaps. This enhances the dustproof effect of the device while also making disassembly and assembly convenient. The wiring slot can be quickly opened for cable inspection or replacement. By adding a dustproof ring at the cable connection point, a dustproof barrier is formed to prevent external dust from entering and corroding the insulation material, improving the insulation performance and durability of the device, reducing the risk of short circuits and leakage, and ensuring safe and stable electrical wiring.

[0008] This utility model uses the cooperation of a lever, lever groove, and sliding hole to guide and limit the movement of the mounting half-shell and the control half-ring, increasing the control fulcrum for the lock bar and preventing the control half-ring from shifting. The engagement of the convex rod and convex rod hole reinforces the overall structure of the control half-ring, allowing the upper and lower control half-rings to be controlled synchronously. When the control half-ring is pushed inwards to completely disengage the lock bar from the lock groove, the braking fulcrum of the threaded half-shell on the nut disappears. At this point, the nut can be quickly removed by rotating it, and the upper and lower junction boxes can be separated to inspect and maintain the cables in the wiring groove. After the nut is fixed by the threaded half-shell, releasing the control half-ring allows it to automatically return to its original position, driven by the spring force, and embedded in the lock bar. This increases the braking fulcrum of the threaded half-shell on the nut, preventing the nut from loosening due to vibration during long-term use and ensuring the sealing effect of the dust seal and the stability of the device.

[0009] This utility model features a bidirectional lead screw and a forward / reverse thread positioning between the two side clamps, combined with a guide limit between the slider and the slide rail. This allows the two side clamps to be moved towards or away from each other by rotating the knob, and to clamp the cable by moving closer together simultaneously, preventing the connection point from loosening due to force. In addition, the clamps are equipped with rubber pads, which can increase the frictional resistance between the contact surface with the cable and improve the stability of the cable. At the same time, the rubber pads have a certain degree of elasticity, which can avoid hard clamping and damage to the external insulation material of the cable.

[0010] This utility model is dustproof, preventing external dust from entering and corroding the insulating material, improving the insulation performance and durability of the device, reducing the risk of short circuits and leakage, while also providing stable clamping to prevent loosening of the wiring due to stress, ensuring safe and stable electrical wiring, and is easy to disassemble and assemble, facilitating cable inspection or replacement, and improving the efficiency of electrical installation work.

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments: Example 1: An electrical installation wiring device includes a nut 02, a dustproof ring 03, a junction box 06, a locking bar 09, a control half-ring 16, a bidirectional lead screw 20, and a clamping plate 24. The junction box 06 has a wiring groove 27 in the middle, and mounting half-shells 05 at both ends. The mounting half-shells 05 have threaded half-shells 04 on their exterior, and a fixing groove 26 inside. The fixing groove 26 is adapted to a cable 01 and connects to the cable 01. The cable 01 connects to the inside of the dustproof ring 03, and the nut 02 is connected to the outside of the dustproof ring 03. The nut 02 is threadedly connected to the threaded half-shell 04. The nut 02 has locking grooves 10 on both sides, and the mounting half-shell 05 has a storage groove 12. The storage slot 12 and locking slot 10 are compatible with the locking bar 09. The outer end of the locking bar 09 is connected to the locking slot 10, and the inner end of the locking bar 09 is connected to the spring 11. The spring 11 is connected to the installation half-shell 05. The junction box 06 adopts the docking structure of upper junction box 061 and lower junction box 062. With the precise engagement of the docking plug 07 and docking slot 08, the area of ​​the junction box 27 is sealed. The threaded half-shells 04 at both ends of the junction box 06 are fixedly connected to the nuts 02 through the threads, which increases the stability and tightness of the connection between the upper junction box 061 and lower junction box 062, prevents the two from separating and causing connection gaps, and enhances the dustproof effect of the device. At the same time, the disassembly and assembly are convenient. The junction box 27 can be quickly opened for cable inspection or replacement. By adding a dustproof ring 03 at the connection with the cable 01, a dustproof barrier is formed to prevent external dust from entering and corroding the insulation material, improving the insulation performance and durability of the device, reducing the risk of short circuit and leakage, and ensuring the safety and stability of electrical wiring.

[0020] Example 2: The present invention relates to an externally connected control half-ring 16 for the mounting half-shell 05. The control half-ring 16 has a lever 13, the mounting half-shell 05 has a sliding hole 15, and the locking bar 09 has a lever groove 14. The lever groove 14 and the sliding hole 15 are adapted to the lever 13. The lever 13 passes through the sliding hole 15 and is connected to the lever groove 14. The control half-ring 16 is divided into an upper control half-ring 161 and a lower control half-ring 162. The upper control half-ring 161 is connected to... The lower control half-ring 162 has protruding rods 17 on both sides, and the upper control half-ring 161 has protruding rod holes 18 on both sides. The protruding rods 17 and protruding rod holes 18 are adapted to each other and pass through the protruding rod holes 18. The mounting half-shell 05 and the control half-ring 16 are guided and limited by the cooperation of the lever 13, lever groove 14, and sliding hole 15. This increases the control fulcrum of the lock bar 09 and prevents the control half-ring 16 from shifting. The rod 17 engages with the protruding rod hole 18, reinforcing the overall structure of the control half-ring 16, allowing the upper control half-ring 161 and the lower control half-ring 162 to be synchronously controlled. When the control half-ring 16 is pushed inward to completely disengage the locking bar 09 from the locking groove 10, the braking fulcrum of the threaded half-shell 04 on the nut 02 disappears. At this time, the nut 02 can be quickly removed by rotating it, and separated through the upper junction box 061 and the lower junction box 062 to inspect and maintain the cable 01 in the wiring groove 27. After the nut 02 is fixed by the threaded half-shell 04, the control half-ring 16 is released, and it is automatically reset to the locking bar 09 embedded in the locking groove 10 by the elastic force of the spring 11. This increases the braking fulcrum of the threaded half-shell 04 on the nut 02, preventing the nut 02 from loosening due to vibration during long-term use, and ensuring the sealing effect of the dust seal 03 and the stability of the device.

[0021] Example 3: The junction box 06 of this utility model is divided into an upper junction box 061 and a lower junction box 062. The upper junction box 061 is connected to the lower junction box 062. The upper junction box 061 has multiple docking rods 07, and the lower junction box 062 has multiple docking slots 08. The docking rods 07 are adapted to the docking slots 08 and are connected to the docking slots 08. The lower junction box 062 is connected to a clamping plate 24. The clamping plate 24 is connected to the outside of a rubber pad 25, and the inside of the rubber pad 25 is connected to a cable 01. This device is dustproof, preventing external dust from entering and corroding the insulating material, improving the insulation performance and durability of the device, reducing the risk of short circuits and leakage, while providing stable clamping to prevent the wiring from loosening under stress, ensuring safe and stable electrical wiring, and is easy to disassemble and assemble, facilitating cable inspection or replacement, and improving the efficiency of electrical installation work.

[0022] Example 4: The lower junction box 062 of this utility model has a slide rail 22, and the clamping plate 24 has a slider 23. The slider 23 is connected to the slide rail 22 and slides within the slide rail 22. The bidirectional lead screw 20 passes through the lower junction box 062 and the slider 23 in sequence. The bidirectional lead screw 20 is connected to the slider 23 by a thread. The two ends of the bidirectional lead screw 20 are connected to knobs 21. The knobs 21 fit against the lower junction box 062. The bidirectional lead screw 20 and the clamping plates 24 on both sides are positioned by the positive and negative threads. With the guide limit between the slider 23 and the slide rail 22, the clamping plates 24 on both sides can be driven to move towards or away from each other by rotating the knobs 21. The cable 01 is clamped by moving closer together at the same time to prevent the connection from loosening due to force. In addition, the clamping plate 24 is provided with a rubber pad 25, which can increase the frictional resistance between the contact surface with the cable 01 and improve the stability of the cable 01. At the same time, the rubber pad 25 has a certain elasticity, which can avoid hard clamping and damage to the external insulation material of the cable 01.

[0023] Example 5: Installation steps: First, assemble the junction box 06 structure. Place the spring 11 and locking bar 09 into the storage slot 12, ensuring the lever slot 14 corresponds to the sliding hole 15. Then, place the control half-ring 16 outside the mounting half-shell 05, and insert the lever 13 through the sliding hole 15 into the lever slot 14, fixing it to the locking bar 09. Next, place the clamping plate 24 into the wiring slot 27 of the lower junction box 062, embedding the slider 23 into the slide rail 22. Then, pass the bidirectional lead screw 20 through the lower junction box 062 and slider 23, with both ends of the bidirectional lead screw 20 connected to the sliders 23 on both sides via positive and negative threads. Finally, place the knob 21 outside the lower junction box 062 and fix it to the outer end of the bidirectional lead screw 20, ensuring the inner surface of the knob 21 is flush with the lower junction box. After the outer surfaces of 062 are fitted together and the junction box 06 structure is assembled, the cable 01 is passed through the nut 02 and placed into the fixing groove 26 and the wiring groove 27 in sequence. After the connection between the two ends of the cable 01 is completed, the two clamping plates 24 on both sides are moved relative to each other by rotating the double-sided screw 20 to clamp the cable 01. Then, the upper junction box 061 is fastened to the upper part of the lower junction box 062, and the docking rod 07 is inserted into the docking slot 08. The protruding rod 17 passes through the protruding rod hole 18. Then, by pushing the control half ring 16 inward, the locking bar 09 is retracted into the storage groove 12. Finally, after the nut 02 is fixedly connected to the threaded half shell 04 through the thread, the control half ring 16 is released. It is pushed by the elasticity of the spring 11 and automatically resets to the locking bar 09 embedded in the locking groove 10, completing the installation.
