Electromagnetic system of clapper type magnetic latching relay, and assembly method thereof

Abstract

The invention relates to an electromagnetic system of a clapper type magnetic latching relay for solving the problem that the existing electromagnetic system of the magnetic latching relay is unsteadyin structure, unreliable in operation and difficult to adjust magnetic attraction force. The electromagnetic system of the clapper type magnetic latching relay comprises an electromagnetic part and ayoke component; the yoke component comprises a yoke; a pressure spring is arranged outside the vertical part of the yoke; a magnetic conduction block is arranged at the inner side; a rectangular holeis arranged on the vertical part of the yoke; furthermore, both the pressure spring and the magnetic conduction block are connected with the yoke; magnetic steel is arranged between the vertical partof the yoke and the magnetic conduction block; the electromagnetic part comprises a coil; an iron core is arranged in the coil in a penetrating manner; furthermore, the upper end of the iron core extends to be above the coil; the vertical part of the yoke is positioned at one side of the coil; the horizontal part of the yoke is connected with the iron core; an armature is arranged at one side ofthe yoke away from the coil; the straight part of the armature is connected with the upper end of the iron core; and a push card square hole is on the bended part of the armature. The electromagneticsystem of the clapper type magnetic latching relay has the advantages of being simple and steady in structure, reliable in operation, easy to adjust the magnetic attraction force and the like.

Description

technical field [0001] The invention belongs to the technical field of circuit control, and in particular relates to an electromagnetic system of a snap-in type magnetic latching relay and an assembly method thereof. Background technique [0002] Magnetic latching relay is an electronic control device, which belongs to the polarization relay in the category of electromagnetic relay, and plays the role of automatic adjustment, safety protection, conversion circuit, etc. in the circuit. The magnetic latching relay is a new type of relay developed in recent years. Its normally closed or normally open state depends on the action of the magnet. According to relevant information, the contact switching current of the magnetic latching relay on the market can reach up to 150A, and the control coil voltage is divided into DC9V, DC12V, etc., which can generally reach 10,000 times of electrical life, 1,000,000 times of mechanical life, and contact pressure drop <100mV. Therefore, ...

AI Technical Summary

Problems solved by technology

[0004] The above scheme solves the problem that the existing magnetic latching relay electromagnetic system is not suitable for various specific relay products and the magnetic attraction is not easy to adjust to a certain extent. However, this scheme still has many shortcomings. For example, due to the impact resistance between its electromagnetic systems The structural connection method is not outstanding, the vibration resistance is not good, and the operation effect of the electromagnetic system and the entire relay is not reliable
