[0018] 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.

[0019] In order to extend the service life of the conductive copper sheet 2, refer to Figure 1 , Figure 2 and Figure 3As shown, it includes a bus duct body 1, and a plurality of conductive copper sheets 2 are extended outward on both sides of the bus duct body 1. A protective shell 3 for protecting the conductive copper sheets 2 is sleeved on the conductive copper sheets 2. A cavity 4 is provided in the protective shell 3, and a plurality of plug-in slots 5 adapted to the guide copper sheets are provided in the cavity 4. When the bus duct body 1 is not in use, the conductive copper sheets 2 on both sides of the bus duct body 1 are respectively aligned with the corresponding protective shells 3, and the protective shells 3 are moved to insert the conductive copper sheets 2 into the plug-in slots 5. When the conductive copper sheet 2 is inserted, the guide column 8 is first aligned with the guide hole 9, and the guide column 8 is inserted into the guide hole 9. At this time, the conductive copper sheet 2 can be inserted into the plug-in slot 5 through the planned path, and the conductive copper sheet 2 will not be damaged, thereby improving the safety and service life of the conductive copper sheet 2. When the conductive copper sheet 2 is inserted into the plug-in slot 5, the limit block 7 is squeezed. As the spring 6 deforms, the elastic potential energy reacts to the limit block 7, so that the two limit blocks 7 squeeze the conductive copper sheet 2, thereby completing the fixation of the conductive copper sheet 2.

[0020] In order to facilitate the stability of the protective shell 3 after installation, refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the plug-in slot 5 corresponds to the conductive copper sheet 2, and a limit assembly for positioning the conductive copper sheet 2 in the slot is provided in the plug-in slot 5. The protective shell can be fixed to the outside of the conductive copper sheet 2 by the limit assembly to prevent the conductive copper sheet 2 from falling off. The limit assembly includes a spring 6 arranged on the inner wall of the plug-in slot 5, and the spring 6 is connected to a limit block 7 at one end away from the plug-in slot 5. The limit block 7 is arranged in an arc shape on the side facing the insertion side of the conductive copper sheet 2, and the arc-shaped side is so that the conductive copper sheet 2 can be smoothly inserted between the two limit blocks 7, so that the spring 6 can be deformed later, and the elastic potential energy is converted into kinetic energy to react on the limit block 7, so that the two limit blocks 7 clamp and fix the conductive copper sheet 2. The limit block 7 can preferably be made of rubber material to avoid friction on the surface of the conductive copper sheet 2, thereby causing damage. Two sets of limit assemblies are arranged in each of the plug-in slots 5, and the limit assemblies in the same horizontal direction are symmetrically arranged. The symmetrically arranged limit assemblies can further improve the clamping of the conductive copper sheet 2. Four guide posts 8 are arranged at equal intervals around the protective shell 3 toward the outside of the conductive copper sheet 2. A guide hole 9 compatible with the guide post 8 is opened on the outside of the bus duct body 1. When the protective shell 3 is installed, the guide post 8 is inserted into the guide hole 9, so that the conductive copper sheet 2 can be inserted into the plug-in slot 5 in the direction of a preset path, thereby completing the installation of the protective shell 3.

[0021] When in use, first, when the bus duct body 1 is not in use, align the conductive copper sheets 2 on both sides of the bus duct body 1 with the corresponding protective shells 3 respectively, move the protective shells 3, and insert the conductive copper sheets 2 into the plug-in slots 5. When the conductive copper sheets 2 are inserted, first, the guide columns 8 are aligned with the guide holes 9, and the guide columns 8 are inserted into the guide holes 9. At this time, the conductive copper sheets 2 can be inserted into the plug-in slots 5 along the planned path, and the conductive copper sheets 2 will not be damaged. After the conductive copper sheets 2 are inserted into the plug-in slots 5, the limit blocks 7 are squeezed. As the springs 6 deform, the elastic potential energy is reacted to the limit blocks 7, so that the two limit blocks 7 squeeze the conductive copper sheets 2, thereby completing the fixation of the conductive copper sheets 2.

[0022] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
