Please refer to FIG. 2 , FIG. 3 and FIG. 4 again, the plug member 3 moves between open and closed positions relative to the insulating body 1 . When the plug is in the open position, the insulating body is formed with an insertion opening 101 for the flexible printed circuit board 200 to be inserted into the docking space 111, and when the plug is in the closed position, the connection between the flexible printed circuit board 200 and the terminal 2 electrical contact.

Please refer to Fig. 1, Fig. 2, Fig. 4 and Fig. 5, the plug member 3 has a longitudinal beam 31 extending along the Y direction, an extrusion part 32 extending from the beam and being accommodated in the docking space 111, and The buckling arms 33 extend from both longitudinal ends of the crossbeam. The buckling arms can be accommodated in the space formed by the main body 11 and the elastic arm 12 of the insulating body. The side wall 114 of the insulating body is provided with a guide chute 116 penetrating through the mating surface 110, the guide chute has two side surfaces 102 extending parallel to each other, and the buckle arm 33 of the plug is provided with The guide slider 331 protrudes into the guide slide chute 116; in this embodiment, the guide slide chute includes three sections, which are respectively the parallel section 103 running through the butt joint surface, the arc section 104 connecting the parallel section, and the Another parallel segment 105 extends from the arc segment.
