Terminal members of an electric tool for receiving detachable tips

Abstract

Terminal members of an electric tool, such as a soldering iron or the like, for receiving detachable tips wherein each tip has a pair of electrical conductors which are detachably secured to the terminal members. Each terminal member is an electrically conducting member having a longitudinal bore to receive a tip conductor, the mouth of the bore preferably being conically countersunk to facilitate conductor entry. A spring member, secured to the terminal member by a set screw inserted into a threaded opening intersecting the longitudinal bore remote from the mouth thereof, has a portion overlying the bored end of the member, the portion being movable transversely in opposition to spring bias. The overlying portion of the spring member has an opening therein to receive a tip conductor, the opening when the spring member is unflexed being misaligned with the bore, whereby the spring member is flexed to align the opening and bore to receive a conductor, and the conductor is detachably secured mechanically and electrically to the terminal member by action of the flexed spring member.
