Abstract
A screwless electrical terminal comprises a connector bar and a clamping cage embracing the bar and biassed by a spring to clamp a conductor between the bar and the cage bottom. The cage can be latched open for example by teeth on the rear of the cage engaging recesses on the connector bar, to allow insertion of a conductor. The cage has a forwardly and downwardly projecting pivot element which engages a fixed abutment if traction on the conductor causes the cage to move along the connector bar. Such movement brings the pivot element into engagement with its abutment and thereafter causes the cage to tilt so as to increase the conductor-clamping force in response to traction on the conductor.
