WIPO Patent Application WO/2019/039233

A1

This electrical connection device is provided with: a probe (10) which comprises a top-side plunger (121) and a bottom-side plunger (122), the tip of each exposed from the open ends at both ends of a barrel (11), and which comprises a stopper region (13) formed in an intermediate region between the two ends of the barrel (11) and having an outer diameter different from that of the main body portion of the barrel (11); and a probe head (20) which comprises a middle guide (23) through which is passed whichever of the stopper region (13) and the main body section of the barrel (11) has the smaller outer diameter and through which cannot pass whichever thereof has the larger outer diameter, and which retains the probe (10) in a state in which the thinner region has been passed through the middle guide (23). The probe (10) is configured to be capable of expanding and contracting in the axial direction between the two ends and the stopper region (13), and when the probe (10) is expanded or contracted in the axial direction, the relatively larger region presses against the middle guide (23).
