摘要： An A-base utility meter cover assembly is described. The meter cover assembly is fabricated of a thermoplastic injection molding material, such as polycarbonate, and includes a base cover covered by a terminal cover. In one embodiment, the base cover includes a terminal block cavity for receiving a utility meter terminal block, and two locking tabs and a snap portion which engage openings through the terminal cover when the base cover and terminal cover are in an assembled configuration. In the assembled configuration, a dam and deflectors on the terminal cover are aligned with ribs on the base to form a continuous barrier against water flow into the terminal block cavity. The configuration of the locking tabs and snap portion also protect against tampering with meter electronics by preventing removal of the terminal cover.
