Abstract
The utility model discloses a cover piece of an electric energy meter. The cover piece comprises a window (1) and a cover plate (2), wherein the window (1) is provided with a clamping slot (1.1) and a button hole (1.2); the cover plate (2) is hinged to the window (1); a first ring-shaped protrusion (1.1.1) is formed on the outer side edge of the clamping slot (1.1) and used for retaining water; and a second ring-shaped protrusion (1.2.1) is formed on the outer side edge of the button hole (1.2) and used for retaining water. The cover piece of the electric energy meter prevents water from entering through the clamping slot and the button hole, so as to ensure the performance of the electric energy meter.
Description
Technical field
The utility model relates to the electric energy meter technical field, specifically is a kind of electric energy meter case.
Background technology
A kind of plug-in card electric energy meter case is arranged at present; It comprises forms and cover plate; Be provided with the draw-in groove and the button hole that are used for inserted IC card in the pit of these forms, this cover plate prevents that with hinged and can be embedded in the pit of forms with forms external substance from entering into electric energy meter from draw-in groove or button hole.There is following shortcoming in the electric energy meter case of prior art: because the outer ledge of draw-in groove and button hole is the plane, when cover plate was opened, water may flow in the electric energy meter from draw-in groove and button hole like this, thereby influenced the performance of electric energy meter.
The utility model content
The technical matters that the utility model will solve is to provide a kind of water of avoiding to get into from draw-in groove and button hole, thereby guarantee the electric energy meter case of electric energy meter performance.
The technical scheme of the utility model is; A kind of electric energy meter case with following structure is provided; It comprises forms and cover plate, and said forms are provided with draw-in groove and button hole, and said cover plate and forms are hinged; The outer ledge of said draw-in groove is provided with first annular protrusion of dash, and the outer ledge of said button hole also is provided with second annular protrusion of dash.
