Abstract
A clip-on electrical terminal block has an earth terminal which grips one flange of a channel-section support rail with outwardly turned flanges. To prevent the earth terminal from drifting in the case of a flange of tapered cross section, a clamping member of the flange not only engages the underside of the flange but also has an inner arm which engages the internal surface of the channel-section rail. A single clamping screw clamps together the earth conductor, the clamping member of the terminal, and the flange of the support rail, by means of a lower arm of the clamping member. To facilitate access to the clamping screw in the case of a terminal block with stacked terminals, the region of the terminal block housing containing the earth terminal may be laterally offset.
