Wherein, when the circuit board 63 is pressed down so that the insertion piece 62 is relatively inserted into the wire-free elastic piece 64, the thrust force exerted by the insertion piece 62 on the wire-free elastic piece 64 will cause the wire-free elastic piece 64 to bend. At this time, due to the insufficient structural strength of the solder-free shrapnel 64 itself, fractures often occur, resulting in poor contact between the insertion piece 62 and the circuit board 63, resulting in the yield rate and product reliability of the electronic device. cannot be effectively increased. Therefore, the wire-free shrapnel 64 in the prior art still needs to be further improved.
