Abstract

A spring connector comprises a supporting member, a cylindrical plunger, and a coil spring provided in the cylindrical plunger. The supporting member has a base, a pillar extended from the base, and a shoulder and a head having a diameter larger than that of the pillar. The upper end of the head has an inclined surface. The plunger has a closed upper end, an opening formed in an annular bent portion of a lower end thereof. An annular edge of the opening is slidably engaged with the supporting member at the shoulder thereof. The coil spring is provided between the closed upper end and the inclined surface of the head so that a shoulder formed on the head at a lower annular periphery is pressed against the annular bent portion of the opening.
