Abstract
A base for an electric utility watt-hour meter made from a polycarbonate material preferably reinforced with glass fiber and ultraviolet light stabilized. The molded base receives current terminals that have outwardly directed lugs engaging one face of the base and there are locking arms on the other side of the base resiliently biased against the lug to engage a locking formation thereon. The base has a knife-edge rib extending about its periphery to sealingly engage a front edge face of a cup shaped transparent cover for the meter. A metal ring joins the cover to the base the metal ring being a band with a first series of lugs struck out and directed inwardly to engage the flange on the cover and a second group of tabs struck outwardly and bent inwardly to engage the bayonet ramp surfaces on the base.
