During preparation, multiple capacitors are stacked between two opposing frames with lead terminals provided on the frames. However, existing large-size chip molded pulse capacitors are limited by the properties of the molded materials. When the size and chip reach a certain level, they are prone to cracking and delamination, which needs further improvement. Summary of the Invention

[0011] Furthermore, a gap is formed between the side surface of the first connecting groove and the first connecting rod or the second connecting rod, and a gap is formed between the side surface of the second connecting groove and the first connecting rod or the second connecting rod.

[0012] Furthermore, the second connecting section is buckled with the first connecting section located on the same first connecting rod or the second connecting rod in upper and lower positions, and is respectively located on both sides of the first connecting rod or the second connecting rod.

[0013] Furthermore, the first connecting section includes a first vertical section and a second vertical section arranged opposite to each other, and a horizontal section arranged between the first vertical section and the second vertical section.

[0017] From the above description of the utility model, it can be seen that compared with the prior art, the beneficial effect of the utility model is: the present application limits the structure of the frame and further limits the structure of the welding plate assembly, so that after the frame is assembled with several large-size capacitor chips, it can be molded to form a capacitor group, ensuring that the prepared multi-core pulse capacitor is not prone to cracking and delamination during subsequent use, and has high reliability.

For further elaboration, the first pin 13 and the second pin 14 are staggered front to back; further, the number of the first connecting rods 12 is greater than the number of the second connecting rods 22, and the number of the second connecting rods 22 is odd, and the number of the first connecting rods 12 is plural, so that the two sides of the frame are exactly the first connecting rods 12, and the multiple second connecting rods 22 and the remaining first connecting rods are alternately arranged between the two first connecting rods 12 at the end; further, the second connecting rods 22 are copper rods.

[0028] Multiple pad assemblies 3 are arranged between adjacent first connecting rods 12 and second connecting rods 22. The pad assemblies 3 include multiple first welding pads 31 arranged at intervals on the first connecting rod 12 and multiple second welding pads 32 arranged on the adjacent second connecting rod 22 opposite to the multiple first welding pads 31, or multiple first welding pads 31 arranged at intervals on the second connecting rod 22 and multiple second welding pads 32 arranged on the adjacent first connecting rod 12 opposite to the multiple first welding pads 31.

[0029] The first welding plate 31 includes a first connecting section 311 connected to the first connecting rod 12 or the second connecting rod 22 and a first welding plate 312 arranged on one side of the first connecting section 311 and extending in a direction close to the adjacent second connecting rod 22 or the first connecting rod 12.

Specifically, the first connecting section 311 includes a first vertical section 314 and a second vertical section 315 arranged opposite to each other, and a first vertical section 316 arranged on the first vertical section 317. A horizontal section 316 is formed between the straight section 314 and the second vertical section 315, wherein the height of the first vertical section 314 is lower than the height of the second vertical section 315, and the first connecting groove 313 is formed between the first vertical section 314 and the second vertical section 315, and the first welding pad 312 is connected to the top of the first vertical section 314; further, a gap is formed between the side surface of the first connecting groove 313 and the first connecting rod 12 or the second connecting rod 22, allowing the first welding pad 31 to deform appropriately, and its connection strength remains unchanged during the deformation process.
