Description

Technical Field

[0001] The utility model relates to the technical field of instrument housings, in particular to an instrument housing with good sealing performance for outdoor use. Background Art

[0002] Meters are a general term for instruments that display numerical values, including digital display meters, watt-hour meters, pressure meters, flow meters, and various analytical instruments. In the power supply and distribution system, electric energy meters and digital display meters are often needed. The shells of existing electric energy meters, digital display meters and other instruments include a base, a cover body arranged on the base, and a wiring terminal block and a signal terminal block respectively arranged on the base. There are many types of instruments with different functions on the market. The structures of the wiring terminal blocks and signal terminal blocks installed on instruments with different functions are different. The instrument shell is a supporting device that protects the internal components of the instrument, generally including components such as the shell, panel, lining plate, and bracket.

[0003] The existing instrument housing panel is often exposed to the natural environment when used outdoors. There is a certain gap between the buttons on the panel and the housing. When the instrument is used in an environment with a lot of dust or water vapor, dust or water vapor often easily enters the inner side of the housing through the gap between the buttons and the housing, which can easily cause failures in the internal components of the instrument housing, not only causing damage to the instrument, but also affecting the normal use of the instrument. The poor sealing effect brings great inconvenience to the user and affects the use of the instrument. In view of the above problems, we propose an improved and upgraded instrument housing with good sealing for outdoor use. Utility Model Content
