Problems solved by technology

The contact system is an important part of the relay, its performance affects the life and safety of the product, and arc ablation is the biggest culprit for damaging the contact system. The arc extinguishing effect is not good due to the power-off delay of the instantaneous moving contact and the static contact. In view of the above problems, it is necessary to study an electromagnetic relay that overcomes the above problems.

Abstract

The invention discloses an electromagnetic relay, which belongs to the field of relays and includes a base, a cover, a magnetic circuit system and a contact system installed on the base, the magnetic circuit system includes an iron core, a coil, an armature and a yoke, and the contact system It includes a static contact group and a dynamic contact group that are set opposite to each other; a push plate is connected between the armature and the dynamic contact group, and a mounting groove for installing the contact system is opened on the base. The slider and the second slider for installing the static contact group, a hinged strip is connected between the upper end of the first slider and the lower end of the second slider, and the middle part of the hinged strip is fixed and connected to the base fixed shaft on the seat. The invention can reduce the ablation time when the contact resistance tends to zero and the pull-in and release rebound, thereby speeding up the arc-extinguishing speed of the relay and improving the arc-extinguishing effect; it can increase the creepage distance between the electromagnetic system and the contact system, so that It is suitable for relays with smaller external dimensions.

Description

technical field [0001] The invention relates to the field of relays, in particular to an electromagnetic relay with good arc extinguishing effect. 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 components. The contact system is an important part of the relay, its performance affects the life and safety of the product, and arc ablation is the biggest culprit for damaging the contact system. The arc extinguishing effect is not good due to the delay of power failure of the instantaneous moving contact and the static contact. In view of the above problems, it is necessary to study an electromagnetic relay that overcomes the above problems. Contents of the invention [0003] 1. Technical problems to be solved [0004] The technical problem to be solved by the present invention is t...
