A magnetic circuit system with only iron core and its relay

Abstract

The invention discloses a magnetic circuit system with only an iron core and a relay thereof. The magnetic circuit system includes a coil and an iron core; the iron core is a bar shape integrally formed by a mold, and one end of the bar shape is also integrally formed There is a pole surface; the bar-shaped part of the iron core is bent twice to form the first and second bending parts and form a U-shape, and the coil is fitted in the U-shaped iron core, and the U-shape The U-shaped mouth can be used to mate with the armature of the relay. Through the improvement of the structure of the magnetic circuit, the invention has the characteristics of lower cost, fewer procedures, higher magnetic permeability and larger pole surface area.

Description

technical field [0001] The invention relates to the technical field of relays, in particular to a magnetic circuit system with only an iron core and a relay thereof. Background technique [0002] Relay is an automatic switching element with isolation function, which is widely used in communication, automobile, automatic control, household appliances and other fields, and is one of the most important control elements. [0003] Relays are divided into monostable, bistable, AC, and DC. Different application fields have different requirements for relays with different functions. The bistable relay can keep the relay in the closed or open state without additional power consumption; the AC relay can meet the requirements of the application fields that require AC input. With the rapid development of household and industrial control, the use of relays is also increasing, and the cost has become a very important competitiveness; the magnetic circuit system is the core component of t...
