Background
In the prior art, the pin connection mode of the busbar and the X & Y capacitor is to directly weld the pin on the surface of the busbar. The thickness of the busbar is close to that of the capacitor pin, for example, the capacitor pin is phi 0.8mm, and the thickness of the busbar is 1 mm. Aiming at a product with the bus-bar thickness of 3mm, because the thickness difference of the two materials is very different and the heat-conducting property of C1100 is very good, the capacitor pins are difficult to weld on the bus-bar by adopting the resistance welding mode. Or the capacitor pin is broken during welding, but the welding tension after welding is lower, and the product is directly broken during vibration test or mechanical impact, so that the function is failed. In addition, the welding process is complex, and manual or jig fixing is needed for fixing the busbar and the capacitor pins. Finally, for products with nickel plating, it is difficult to solder, typically using bare copper or direct tin plating, but not applicable for products with high requirements for salt spray testing.
