Abstract

The invention discloses an ammeter housing and an ammeter, for solving the problems of difficult dissipation of heat generated by a conventional ammeter shunt and affected measuring precision. The ammeter comprises electronic components, a cover and the ammeter housing. The ammeter housing comprises an accommodation housing, the accommodation housing comprises a wiring cavity and an electric appliance cavity for accommodating the electronic components, the wiring cavity is internally provided with a terminal box, the terminal box is internally provided with a shunt, multiple wiring terminals and multiple function terminals, the shunt is arranged behind the wiring terminals, the shunt is provided with a lead wire penetrating the terminal box for connection with the electronic components in the electric appliance cavity, the terminal box comprises a base and a cover plate, the shunt is arranged on the base, and the base and the cover plate cooperate to form an accommodation isolation cavity for isolating the shunt from the electric appliance cavity. The ammeter housing and the ammeter have the advantages of simple structure, convenient assembling, good heat dissipation performance, high measuring accuracy, reliable wiring, small energy consumption, low fault rate and the like.

Description

technical field [0001] The invention relates to an electric meter, in particular to an electric meter shell and the electric meter. Background technique [0002] The electric meter is the abbreviation of the electric energy meter, which is used to Measurement Electric energy meters, also known as watt-hour meters, fire meters. The upper cover and base of the existing electric meter terminal box have many and complicated processing procedures, which are not easy to automate and simplify the process; the integrated structure is lower than the waterproof level, it is difficult to meet the waterproof level of IP54 or higher, and it is easy to seep water. In addition, the existing terminal box divides the ammeter case into two accommodating chambers. The shunt and the ammeter function module are sealed in one chamber (in the electrical chamber), and the wiring terminals are in the other chamber (in the wiring chamber). During installation, the shunt is welded on the connection ...
