Magnetic flow convertor with permanent magnet

Abstract

The invention relates to a magnetic flow convertor with a permanent magnet, which comprises a magnetic yoke, the permanent magnet, a coil framework, a coil, mandrils, a spring, a jump spring and a buffer cushion, wherein the coil is wound on the coil framework, the permanent magnet is placed in the coil framework, the magnet yoke is also used as a casing of the magnetic flow convertor, the coil framework is also used as a cover of the magnetic flow convertor, the mandrils are absorbed on the permanent magnet in a suction state, the magnet yoke has two fixed jaws symmetrically arranged at two sides, the inside of the coil framework is divided into three cavities, the permanent magnet is placed in a circular cavity at the bottom of the coil framework, mandrils are placed in circular cavities at the middle part and the upper part of the coil framework, and the diameter of the cavity at the middle part is more than that of the cavity at the upper part so as to be used for limiting the mandrils. The structure of the magnetic flow convertor is improved, an air gap among the permanent magnetic and the mandrils is removed, the volume of the magnetic flow convertor is reduced; the coil framework can be used for limiting and fixing the permanent magnet and the mandrils and has the functions of the casing and the cover, thereby reducing the parts, lowering the production cost and being convenient for installation.

Description

technical field [0001] The invention relates to a magnetic flux converter, in particular to a magnetic flux converter with permanent magnets, belonging to the technical field of low-voltage electrical appliances. Background technique [0002] Any low-voltage electrical appliances are structurally composed of two parts, the sensing organ and the executing organ. The sensing organ receives the input signal, makes a judgment after detection and comparison, and then commands the organ to execute the action and output the signal command to achieve the purpose of control. The sensing mechanism is generally an electromagnetic system, bimetal, etc.; the actuator is generally a contact arc extinguishing system or a contact, which disconnects the circuit or sends a signal. [0003] With the development of micro-processing technology, low-voltage electrical appliances are developing towards digitalization. In digital electrical appliances, the sensing mechanism is generally completed...

AI Technical Summary

Problems solved by technology

The device includes all the components of the magnetic flux converter. The structure of the shell and the cover is complicated, and the production process of the whole device is complicated. Because it includes permanent magnets, tripping coils, armatures, ejector rods and other parts, the volume is relatively large.
