[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0028] In order to improve the stability of the incoming line node 3 when inserted into the power distribution cabinet, refer to Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6As shown, it includes a bus duct body 1, and an incoming line section 3 is provided at one end of the bus duct body 1. The incoming line section 3 and the outgoing line section 2 are the starting bus and the terminal bus respectively. The bus duct body 1 is connected to the power distribution cabinet, and the incoming line section 3 needs to be connected to the row in the power distribution cabinet. A guide block 5 for connecting the bus duct body 1 to the distribution box is provided on the outside of the incoming line section 3. A soft connection circuit board is provided in the guide block 5. When the wiring barrel 7 is inserted into the plug slot 4, the lead 9 can be connected to the circuit board, so that the current can be transmitted to the wiring barrel 7. The guide block 5 is provided with a terminal barrel 7 softly connected to the circuit board in the distribution box on the side away from the bus duct body 1. A limiting component is provided on the outer side of the terminal barrel 7 for stabilizing the terminal barrel 7 after the soft connection with the distribution box circuit board. By inserting the terminal barrel 7 into the terminal post 10, the external thread cutter is inserted into the limiting hole 13 and rotated, which drives the second screw 19 to rotate. As the first screw 12 rotates in the threaded hole 11 and engages with the two limiting posts 21, the card interfaces 17 on the two limiting posts 21 are carded onto the extension 8 on the terminal barrel 7, thereby fixing the incoming line section 3 softly connected to the circuit board in the distribution box.

[0029] In order to facilitate the fixing of the incoming line section 3, refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the guide block 5 is provided with a plug-in slot 4 adapted to the incoming line section 3 on one side close to the busbar trunk body 1, and a circuit board is provided in the plug-in slot 4 for current to flow to the wiring barrel 7, so as to facilitate the subsequent current transmission. The plug-in slot 4 is provided with a sliding unit for reducing the friction when the incoming line section 3 enters the plug-in slot 4, and the sliding unit includes a groove provided on the inner wall of the slot opening of the plug-in slot 4, and the plug-in slot 4 is provided in multiple numbers, and each of the upper and lower walls of the plug-in slot 4 is provided with a groove, and a connecting rod 15 is provided in the groove, and a roller 16 is provided on the connecting rod 15, and a connecting rod 15 and a roller 16 are provided in each groove.

A second screw rod 19 is arranged between the two limiting posts 21, and a limiting hole 13 is arranged on the side of the two limiting posts 21 that are separated from each other. The limiting hole 13 is rotated by an external tool, so as to drive the rotation of the second screw rod 19. The two limiting posts 21 are provided with a plug hole, and the plug hole is provided with a thread matching the outer thread of the second screw rod 19. When the second screw rod 19 rotates, the two limiting posts 21 can rotate on the second screw rod 19, and the two limiting posts 21 move through the rotation limit of the first screw rod 12. The second screw rod 19 extends into the limiting hole 13, and a connection port 20 for soft connection with the circuit board is provided in the cavity 18. An extension portion 8 is provided on the outside of the wiring barrel 7, and a lead 9 adapted to the connection port 20 is provided on the side of the wiring barrel 7 close to the terminal 10. The opposite surfaces of the two terminal 10 are provided with a card interface 17 for carding the extension portion 8. When the extension portion 8 is carded in the card interface 17, the wiring barrel 7 is fixed in the cavity 18. The other end of the bus duct body 1 is provided with an outlet node 2.

Under the rotation of the roller 16, the incoming wire section 3 is inserted into the deep end of the plug-in slot 4.

[0032] Step B, then slowly insert the wire barrel 7 into the cavity 18 of the terminal 10, insert the lead wire 9 into the connection port 20, and then insert the thread cutter into the limiting hole 13, rotate the thread cutter to drive the second screw rod 19 to rotate, and as the second screw rod 19 rotates, the two limiting posts 21 move closer to the center of the cavity 18;

[0033] Step C, as the two limiting posts 21 approach the wiring barrel 7, the outer extension 8 of the wiring post 10 is clamped into the clamp interface 17 to fix the wiring barrel 7, and when the two limiting posts 21 face the wiring barrel 7, the first screw 12 rotates synchronously in the threaded hole 11 and fits with the notch 14;
