通过采用动片211的动片弯折部2110与静片212的静片弯折部2120直接电性连接于PCB板,并在PCB板1上增设第一插拔孔13与第二插拔孔14,分别供动片211下端与静片212下端插拔,由此,使得动片211与静片212 具有开关电性导通功能的同时,还具有反复插拔能力。By using the moving piece bending portion 2110 of the moving piece 211 and the static piece bending portion 2120 of the static piece 212 to be directly electrically connected to the PCB board, and adding a first plugging hole 13 and a second plugging hole on the PCB board 1 14. The lower end of the moving piece 211 and the lower end of the static piece 212 are respectively inserted and removed, so that the moving piece 211 and the static piece 212 have the function of switching electrical conduction and also have the capability of repeated insertion and removal.
在本实施例中,所述动片弯折部2110与静片弯折部2120均为弹性体,即动片弯折部2110与静片弯折部2120均具有弹性。同时,所述动片弯折部2110与静片弯折部2120均呈弧形,如图4与图5所示。In this embodiment, the moving piece bending portion 2110 and the static piece bending portion 2120 are both elastic bodies, that is, the moving piece bending portion 2110 and the static piece bending portion 2120 both have elasticity.
