The invention discloses a buckling fuzz button electric connector comprising metal conductors and an insulating base. Each metal conductor comprises an upper fixing cap, a fuzz button and a lower fixing cap. The insulating base comprises a lower base and an upper base. The fuzz button is arranged in the upper base, and the two ends of the fuzz button are fixed by the upper fixing cap and the lower fixing cap respectively. The front part of the lower base is provided with a buckle. The internal side surface of the buckle is provided with a buckle chamfer. The front part of the upper base is provided with base slots. The slot walls of the base slots are inwardly slotted so that clamping slots are formed. The lower base and the upper base are locked through the buckled and the clamping slots. Fine metal lines are wound into a cylinder structure by the fuzz button. The electric connector is rapid in assembling and convenient to maintain and disassemble so that reliable transmission of the electric signals of the electric connector can be realized, the electric connector is suitable for connection of the circuits between printed circuit boards requiring large-scale utilization of the electric connector, the development requirements of miniaturization and dwarfing can be met, and thus the electric connector has high anti-vibration and anti-impact performance and meets the environmental use requirements.
