Abstract

The invention belongs to the technical field of overload protection devices, particularly relates to an electric meter and an overload protection device for the electric meter, and provides the following scheme for solving the problem that an existing overload protection device is complex in structure: the electric meter comprises a shell, a first sliding groove is formed in the inner wall of the rear end of the shell, and a first sliding block is slidably connected in the first sliding groove; a second mounting plate is fixed to the front end of the first sliding block, and a second electrode plate is fixed to the inner side of the second mounting plate; a second spring is fixed to the top of the inner wall of the second groove, and a second clamping block is fixed to the bottom of the second spring; a first mounting plate is fixed to the inner wall of the rear end of the shell, and a first electrode plate is embedded and fixed to the inner side of the first mounting plate; and a permanent magnet is adhered to one side of the first mounting plate. According to the invention, the magnetic field force on the second electrode plate and the permanent magnet interact with each other, so that the first sliding block relieves the constraint of the second clamping block and moves rightwards, the first electrode plate and the second electrode plate are separated from contact, a circuit is cut off, and the circuit and an electric appliance are protected.

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...
