Waterproof ammeter

Abstract

The utility model discloses a waterproof ammeter, which comprises a face shell, a module cover and a sealing element, the face shell is provided with an inclined surface, and the inclined surface is provided with an open window and a pressing ring frame arranged around the open window; the module cover is connected with the face shell and provided with an inclined butt joint face, and the butt joint face is provided with an annular-frame-shaped containing groove. The sealing element is integrally in a ring frame shape and is accommodated in the accommodating groove; the abutting ring frame extends into the containing groove and abuts against the sealing piece so that a continuous and complete ring frame-shaped sealing face can be formed by the abutting ring frame and the sealing piece. The waterproof electric meter is novel in structure, the pressing ring frame on the surface shell forms a retaining wall for preventing water vapor from entering the window through the inclined surface, and the difficulty of water vapor entering the electric meter is increased; the abutting ring frame and the sealing member on the module cover can form a ring frame-shaped sealing surface which is connected completely, so that the waterproof performance of the waterproof ammeter is greatly improved. In addition, due to the fact that the inclined face has a certain inclination angle, water vapor abutting against the outer side of the annular frame can be drained, and water vapor gathering is avoided.

Description

Technical Field

[0001] The utility model relates to the technical field of electric energy meters, in particular to a waterproof electric energy meter. Background Art

[0002] like Figure 1 As shown, the electric meter at least includes a bottom shell 10 and a front shell 1 and a module cover 2 respectively connected to the bottom shell 10, and the electric meter has a functional module 4 arranged corresponding to the module cover 2, and the functional module 4 includes but is not limited to an indicator light module. In order to facilitate the positioning and installation of the module cover 2, a buckle groove structure 20 is provided on the vertical surface 14 of the front shell 1 close to the module cover 2. However, the existence of the buckle groove structure 20 makes it possible to install only a U-shaped seal 30 in the gap between the module cover 2 and the bottom shell 10 for waterproof sealing. However, in actual use, the applicant found that water vapor will enter the interior of the electric meter through the vertical surface 14 of the face shell 1 over the buckle groove structure 20 or enter the interior of the electric meter through the gap between the buckle groove structure 20 and the U-shaped seal 30, thereby resulting in unsatisfactory waterproof performance of the electric meter. Therefore, there is still room for further improvement in the waterproof performance of the electric meter. Utility Model Content
