Abstract

The invention belongs to the technical field of overload protection devices, in particular to an electric meter and an overload protection device used for electric meters. Aiming at the problem of complex structure of the existing overload protection device, the following scheme is proposed, including a housing, and the inner wall of the rear end of the housing There is a first chute, the first slider is slidably connected to the first chute, the front end of the first slider is fixed with the second mounting plate, the inner side of the second mounting plate is fixed with the second electrode piece, the top of the inner wall of the second groove The second spring is fixed, the second block is fixed on the bottom of the second spring, the first mounting plate is fixed on the inner wall of the rear end of the housing, the first electrode piece is nested and fixed on the inner side of the first mounting plate, and one side of the first mounting plate is glued Connected with permanent magnet. In the present invention, the magnetic field force on the second electrode piece interacts with the permanent magnet, so that the first slider releases the restraint of the second block and moves to the right, so that the first electrode piece and the second electrode piece are out of contact. , Cut off the circuit to protect the circuit and electrical appliances.

Description

technical field [0001] The invention relates to the technical field of overload protection devices, in particular to an electric meter and an overload protection device for the electric meter. Background technique [0002] Today's electric power technology is developing rapidly, and the electric meter is inseparable from the process of electric power transmission and use. The electric meter is the abbreviation of the electric energy meter. , The emergence of home appliances has brought about earth-shaking changes in people's lives. Home appliances need to be powered on to work, which requires the use of a power supply. When the current inside the wire is at a normal value, the power supply can normally supply power to household appliances. When the current passing through the wire is at an abnormal value, the power supply cannot normally supply power to household appliances, and if it is serious, it will cause the power supply to burn and explode. [0003] In order to solve...
