[0021] In this embodiment, the copper busbar body 2 is a low-voltage lead copper busbar, and the limiting bolt 10 is a nylon bolt. During use, the base plate 1 is first fixed to the transformer through the mounting plate 7, and the copper busbar body 2 is directly installed above the base plate 1. Specifically, the copper busbar body 2 is placed on the inner side of the first clamping plate 5, and the positioning strip 19 is clamped on the base plate 1 to pre-position the copper busbar body 2. Then, the limiting bolt 10 of the limiting mechanism 4 is rotated. Under the action of the thread, the limiting bolt 10 will push the transverse plate 9 to one side, and the transverse plate 9 and the fixed plate 3 can clamp both sides of the copper busbar body 2.

[0022] See Figure 1-4 The first clamping plate 5 and the second clamping plate 12 are arranged correspondingly. A plurality of engaging holes 15 are provided on one side of the first clamping plate 5. A plurality of engaging columns 13 are connected to one side of the second clamping plate 12. The engaging columns 13 are engaged with the engaging holes 15. A slider 16 is connected to the back of the transverse plate 9.

A rotating torsion bar 14 is fixedly connected to one side of the limit bolt 10.

[0023] In this embodiment, when the limiting bolt 10 is rotated to make the transverse plate 9 approach the fixed plate 3, the second clamping plate 12 will also move close to the first clamping plate 5, and the slider 16 on the back of the transverse plate 9 slides inside the guide groove 17. Finally, the first clamping plate 5 and the second clamping plate 12 are fitted together to limit the front position of the copper busbar body 2, and the locking column 13 can be locked into the locking hole 15.

[0024] See Figure 1-5 The corners of the substrate 1 are fixedly connected with mounting pieces 7, the middle of the mounting piece 7 is provided with a mounting hole 8, both sides of the positioning card strip 19 are clamped with the surface of the substrate 1, and the surface of the substrate 1 is provided with a plurality of heat dissipation holes 18;

Specifically, the copper bar body 2 is placed on the inner side of the first clamping plate 5, and the positioning card strip 19 is clamped on the substrate 1 to pre-position the copper bar body 2. Then, the limiting bolt 10 of the limiting mechanism 4 is rotated. The limiting bolt 10 will push the transverse plate 9 to one side under the action of the thread. When the transverse plate 9 approaches the fixed plate 3, the second clamping plate 12 will also move close to the first clamping plate 5. Finally, the first clamping plate 5 and the second clamping plate 12 are fitted together to limit the front position of the copper bar body 2. The first and second clamping plates 5 and 12 are used to block the front of the copper bar body 2, thereby completing the limitation of the copper bar body 2 and completing the installation of the copper bar body 2. Similarly, when disassembling the copper bar body 2, the limiting bolts 10 are directly loosened, the transverse plate 9 and the fixed plate 3 no longer limit the copper bar body 2, and the copper bar body 2 can be directly taken out after the second clamping plate 12 is moved to the position to one side. The entire low-voltage lead copper bar installation structure facilitates the installation and disassembly of the copper bar, and there is no need to use tools to fix the copper bar with bolts.
