[0018] Please refer to the atta Figure 1 -achment Figure 4, an embodiment provided by the present utility model: a rectifier bridge with a spot welding positioning point structure, including a connecting piece 1, on which a pin positioning component 2 is installed. The pin positioning component 2 includes a through groove 21, in which two first vertical plates 22 are fixedly connected. The bottom end of the first vertical plate 22 is fixedly connected with an arc plate 23, the bottom end of the arc plate 23 is fixedly connected with a second vertical plate 24, one end of the second vertical plate 24 is fixedly connected with a baffle 25, and the bottom end of the second vertical plate 24 is fixedly connected with a first cross plate 26. Two symmetric second vertical plates 24 and the first cross plate 26 form a receiving cavity for the pins. The baffle 25 is used to limit the pins, and the arc plate 23 is also used to limit the pins. The first vertical plate 22 is used to connect the connecting piece 1 and the arc plate 23; on the connecting piece 1, a diode positioning component 3 is installed, and the diode positioning component 3 is arranged on one side of the pin positioning component 2. The diode positioning component 3 includes a third vertical plate 31, a through hole 32, a second cross plate 33, an elastic opening ring 34, an anti-slip pattern 35, a guiding piece 36, a fourth vertical plate 37, a limiting plate 38, an elastic supporting plate 39, a connecting plate 310 and a notch 311. A notch 311 is opened on the connecting piece 1, and a third vertical plate 31 is fixedly connected to the notch 311. The bottom end of the third vertical plate 31 is fixedly connected with a second cross plate 33, and one end of the second cross plate 33 is fixedly connected with an elastic opening ring 34. The third vertical plate 31 is used to connect the connecting piece 1 and the second cross plate 33, and the second cross plate 33 is used to connect the elastic opening ring 34 and the third vertical plate 31; a through hole 32 is opened on the third vertical plate 31, and the through hole 32 is used to accommodate the diode pins; an anti-slip pattern 35 is arranged on the inner wall of the elastic opening ring 34, and the anti-slip pattern 35 is used to increase the frictional resistance between the diode and the elastic opening ring 34 and improve the clamping firmness of the elastic opening ring 34; two guiding pieces 36 are fixedly connected to the outer wall of the elastic opening ring 34, and the guiding pieces 36 are used to guide the diode; two fourth vertical plates 37 are fixedly connected to the top end of the elastic opening ring 34, a limiting plate 38 is fixedly connected to the top end of the fourth vertical plate 37, an elastic supporting plate 39 is arranged at the bottom end of the limiting plate 38, the bottom end of the elastic supporting plate 39 is fixedly connected with a connecting plate 310, and the connecting plate 310 is fixedly connected to the connecting piece 1. The elastic supporting plate 39 limits the limiting plate 38 to prevent the elastic opening ring 34 from folding downwards. At the same time, the elastic supporting plate 39 provides additional reset elastic force for the elastic opening ring 34 through the fourth vertical plate 37, and can also prevent the elastic opening ring 34 from deforming excessively. The fourth vertical plate 37 fits the notch 311 to prevent the elastic opening ring 34 from folding upwards.

[0019] Working principle: When welding a diode onto the present utility model, one end of the diode can be inserted into the elastic opening ring 34 until it is limited by the third vertical plate 31. This process is guided by the guiding piece 36. The anti-slip pattern 35 is used to increase the frictional resistance between the diode and the elastic opening ring 34, improving the firmness of the clamping of the elastic opening ring 34. At the same time, the elastic support plate 39 on the connecting plate 310 limits the limiting plate 38 to prevent the elastic opening ring 34 from folding downwards. Meanwhile, the elastic support plate 39 provides additional restoring elastic force for the elastic opening ring 34 through the fourth vertical plate 37, and can also prevent the elastic opening ring 34 from being excessively deformed. The fourth vertical plate 37 fits the notch 311 to prevent the elastic opening ring 34 from folding upwards. The second horizontal plate 33 is used to connect the third vertical plate 31 and the elastic opening ring 34; the two symmetrical second vertical plates 24 and the first horizontal plate 26 form a receiving cavity for the pins. When one end of the diode is inserted into the elastic opening ring 34, the pins of the diode are inserted into the receiving cavity through the through holes 32 until they are blocked by the baffle 25. During this process, the two symmetrical arc-shaped plates 23 limit the pins. The first vertical plate 22 is used to connect the connecting piece 1 and the arc-shaped plate 23. After one end of the diode is inserted into the elastic opening ring 34, the pre-assembly of the diode can be achieved. By dripping the welding fluid into the receiving cavity through the through groove 21, the welding of the pins can be achieved.
