In the depth direction of the mounting hole 41, the abutting portion 54 is closer to the first connecting portion 51 than the third free end 561.

In embodiment 4, the distance H3 between the third free end 561 and the first connecting portion 51 is greater than the depth T of the mounting hole 41, and H3 > T ensures that the third card 56 can pass through the mounting hole 41, wherein the two first cards 53 are symmetrically arranged with the center line between one side and the other side of the buckle body 521, the distance L3 between the third free end 561 and the center line is greater than 1/2 of the width D of the mounting hole 41, so that the third card 56 is outwardly opened after passing through the mounting hole 41, and the third free end 561 exceeds the edge of the mounting hole 41, so that the PCB 4 is not separated from the third card 56, thereby achieving the purpose that the PCB 4 is clamped between the first connecting portion 51 and the second elastic clamping portion.
