Abstract

A screwless electrical terminal unit comprises a pair of parallel channels for receiving respective conductors, with the open sides of the channels facing one another. Between the channels is mounted a W-shaped leaf spring with its central bend mounted on a retaining member, each outer bend adjoining an abutment between the outer bends to limit movement of the latter, and the free limbs extending obliquely towards respective channels for clamping conductors therein. Such an arrangement ensures that manipulation of one limb of the spring has no effect on the clamping of a conductor by the other limb. A rocker member may be provided for selectively moving the free limbs from their conductor-clamping positions.
