At the same time, the transformer 40 transformer body 401 drives the first connecting copper bar 402 to pass from the top of the assembly board 100 from the second avoidance hole 2 to the circuit board 300 from top to bottom, to prevent the two sides of the first connecting copper bar 402 from being interfered by the second side portion 413 of the anti-collision block 411, and the anti-collision block 411 starts The first connecting copper bar 402 is finally lower than the first connecting copper bar 402, so the first connecting copper bar 402 is always in the limiting channel 42 and will not collide with the capacitor 30 on the circuit board 300. At the same time, the second connecting copper bars 403 on both sides of the first connecting copper bar 402 are located away from the ends of the transformer body 401 of the transformer 40 and are against the first side 412 of the anti-collision block 411, and the right angle formed by the first side 412 and the second side 413 is against the "L"-shaped area formed between the first connecting copper bar 403 and the second connecting copper bar 403, ensuring that when the transformer body 401 of the transformer 40 and the connecting copper bar move downward together, the first avoidance hole 1 and the second avoidance hole 2 respectively guide them.
