Screwless electrical terminal
First Claim
1. An electrical terminal comprising a rigid bent sheet metal member having a first portion provided with a projecting pivot and a second portion spaced from and generally parallel to the pivot, a cam pivotable on the pivot and having an eccentric surface facing the said second portion, and a torsion spring action on the cam to urge the eccentric surface towards the said second portion for clamping, in use, a conductor inserted therebetween, and in which the torsion spring has a helical portion fitted over the pivot, the cam has a bearing aperture fitted over the said helical portion, and the spring has a projecting leg acting on the cam.

Abstract
An electrical terminal comprising a rigid bent sheet metal member having a first portion provided with a projecting pivot and a second portion spaced from and generally parallel to the pivot, a cam pivotable on the pivot and having an eccentric surface facing the said second portion, and a torsion spring acting on the cam to urge the eccentric surface towards the said second portion for clamping a conductor inserted therebetween. Preferably the member is of channel section, its web forming the second portion and a flange forming the first portion. The torsion spring preferably has a helical portion which is fitted over the pivot and on which the cam is fitted, and a leg acting on the cam.
