Abstract
An electric connection device includes a probe (10) and a probe head (20). The probe (10) includes: a tubular barrel (11), a rod-like top-side plunger (121), and a rod-like bottom-side plunger (122). The top- and bottom-side plungers are connected to the barrel (11) with tips thereof exposed from respective open ends of the barrel (11). The probe head (2) includes guide plates (211 and 212) which are spaced apart from each other in the axial direction of the probe (10) and each include a through-hole through which a body of the barrel (11) penetrates. A protrusion (13) having an outer diameter greater than the body of the barrel (11) is provided on the circumference of the probe (10). The guide plates (211 and 212) include a support guide plate in which the through-hole has a diameter smaller than the outer diameter of the protrusion (13). The probe (10) is supported by the support guide plate with the top-side plunger (121) up such that the lower section of the protrusion (13) is in contact with the edge of the upper opening of the through-hole of the support guide plate.
