The outside of the slide post 5 is sleeved with a spring 8, and the spring 8 here is used to reset the button 6.

[0034] Reference Figure 3 - Figure 5 One end of the spring 8 is fixedly connected to one side of the limit block 7, and the other end of the spring 8 is fixedly connected to one side of the inner wall of the box body 1. The limit block 7 and the box body 1 here play a supporting and fixing role for the spring 8. The inner wall of the bottom end of the sliding column 5 is slidably connected with an arc block 9. The arc block 9 here is a shape of large inside and small outside. The arc block 9 and the inner wall of the bus duct body 4 are in a snap-fitting relationship. The inner side wall of the arc block 9 is fixedly connected with a limit plate 10. The limit plate 10 here is used to prevent the arc block 9 from detaching from the inner wall of the sliding column 5. The outside of the position plate 10 is slidably connected to the inner wall of the sliding column 5, and a spring 2 11 is arranged inside the bottom end of the sliding column 5. The spring 2 11 here is used to provide support force for the arc block 9. One end of the spring 2 11 is fixedly connected to one side of the limit plate 10, and the other end of the spring 2 11 is fixedly connected to one side of the inner wall of the sliding column 5. The sliding column 5 and the limit plate 10 here support and fix the spring 2 11. The rear end of the inner wall of the box body 1 is fixedly connected with a wire harness assembly, which is used to ensure the stability of multiple wirings.

[0035] Reference Figure 5 - Figure 6The wiring harness assembly includes a plurality of slide rods 12, the outer portion of the slide rods 12 is slidably connected to the rear end of the inner wall of the box body 1, and the box body 1 here plays a supporting and fixing role for the plurality of slide rods 12, and the front ends of the plurality of slide rods 12 are fixedly connected with a top ring 13, and the inner wall of the top ring 13 is rotatably connected with a plurality of rotating shafts 16, and rotating the top ring 13 here can drive the rotating shaft 16 to rotate, and the other end of the rotating shaft 16 is rotatably connected with a rubber ring 17, and the rotation of the rotating shaft 16 here will drive the rotation of the rubber ring 17, so as to realize the clamping of the wiring harness of the plurality of wires, and the middle part of the rotating shaft 16 is rotatably connected with a rotating column 18, and the front and rear ends of the plurality of rotating columns 18 are rotatably connected with groove rings 19, and the two groove rings 19 here are used to ensure that the rotating column 18 rotates in a circle, and play a role of limiting, and the rear end of the rear end groove ring 19 is fixedly connected to the rear end of the inner wall of the box body 1;

[0036] The front and rear sides of the rotating shaft 16 are both slidably connected to the adjacent sides of the two groove rings 19. The outer rear end of the front end groove ring 19 is fixedly connected to the inner wall of the top ring 13. Here, the top ring 13 supports and fixes the front end groove ring 19. The rear end of the inner wall of the box body 1 is fixedly connected with a reset component, and the reset component is used to reset the wiring harness component. The reset component includes a bottom ring 14. The rear end of the bottom ring 14 is fixedly connected to the rear end of the inner wall of the box body 1. Here, the box body 1 supports and fixes the bottom ring 14. The front end of the bottom ring 14 is fixedly connected with a spring three 15. The other end of the spring three 15 is fixedly connected to the rear end of the top ring 13. Here, the bottom ring 14 is mainly used to cooperate with the top ring 13, so that it rotates together when driving the spring three 15 to rotate, to prevent the spring three 15 from having torque force, thereby affecting the service life of the spring three 15.

[0037] Working principle: First, the staff places the box 1 on the top of the bus duct body 4, and aligns the slide post 5 with the groove of the bus duct body 4, then turns the button 6 to drive the slide post 5 to rotate, so that the spring 1 8 generates a reaction force. The limit block 7 here serves as a limit for the slide post 5 to prevent it from detaching from the inner wall of the box 1. At this time, because the groove of the bus duct body 4 only allows the thickness of one slide post 5, the slide post 5 will be squeezed. When it is squeezed to the maximum limit, the arc block 9 will continue to be squeezed because the bottom end of the arc block 9 is rounded. Therefore, the arc block 9 will slowly shrink into the interior of the sliding column 5. At this time, the sliding column 5 can be inserted into the inner wall of the bus duct body 4. Then release your hand, and the spring 1 8 will start to work. Because of its own torque force during rotation, it drives the sliding column 5 to rotate, so that the position of the arc block 9 is aligned with the groove on the inner wall of the bus duct body 4. At this time, the arc block 9 is rebounded and ejected under the action of the spring 2 11, thereby forming an engagement with the groove on the inner wall of the bus duct body 4. The limiting plate 10 here serves as a limit for the arc block 9 to prevent it from detaching from the inner wall of the sliding column 5, thereby completing the rapid fixation.

[0038] After the staff completes the connection of the wire to this busbar trunking plug-in box, the top ring 13 can be pulled first to disengage the sliding rod 12 from the clamping of the box body 1. Then, the top ring 13 is rotated to drive the rotating shaft 16 to rotate. At this time, the rotating column 18 will rotate on the inner wall of the groove ring 19, so that multiple rotating shafts 16 clamp towards the center, and multiple rubber rings 17 will tightly clamp multiple wires together. After clamping, the top ring 13 can be pressed to make the sliding rod 12 engage with the box body 1 again. The bottom ring 14 here cooperates with the top ring 13 to prevent the third spring 15 from breaking due to torque force during rotation, improving the service life of the third spring 15.

[0039] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
