Abstract

The invention is suitable for the technical field of electric energy meters, and particularly relates to an electric energy meter and a key sealing component thereof. The component comprises a meter cover, a key embedded in the meter cover and an elastic element, wherein the key comprises a key cap and a key pillar protruded out of the inner surface of the key cap; the meter cover is provided with an accommodating cavity which is protruded inwards and used for accommodating the key cap and part of the key pillar; a through hole is formed in the bottom of the accommodating cavity; the key pillar passes through the through hole; the elastic element is elastically supported between the key cap and the bottom of the accommodating cavity; a convex ring encircling the key pillar is outwards protruded out of the bottom of the accommodating cavity; a sealing sleeve is sleeved on the peripheral wall surface of the convex ring; and the sealing ring is used for sealing the ring opening of the convex ring. According to the component, a sealed structure is formed by arranging the sealing sleeve and is well waterproof; and the structure is simple and compact, and the production cost is saved. Furthermore, a sealing ring is provided; and therefore, water cannot penetrate into the component from the through hole, and the waterproof capacity is further improved.

Description

technical field [0001] The invention relates to the field of electric energy meters, in particular to an electric energy meter and a key sealing assembly thereof. Background technique [0002] With the popularization of household appliances, people are increasingly dependent on the living environment with electricity, and the electric energy meter is one of the electronic components that are indispensable for the daily life of residents or the operation of enterprises and institutions. Since the energy meter is in a home environment or a factory environment, and is usually placed on an open wall, it is easy to contact with water. Therefore, waterproof is a problem that the energy meter must overcome. [0003] In the structure of the energy meter, such as the button part, there are gaps in the structure of these parts, which are the key points of waterproofing. At present, the keys of electric energy meters on the market have low waterproof ability, or complex structures, hi...
