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 and belongs to the field of relays. The electromagnetic relay comprises a base, a housing, a magnetic circuit system and a contact system, wherein themagnetic circuit system and the contact system are arranged on the base, the magnetic circuit system comprises an iron core, a coil, an armature and a yoke, the contact system comprises a static contact group and a dynamic contact group which are oppositely arranged, a push plate is connected between the armature and the movable contact group, a mounting groove for mounting a contact system is formed in the base, a first sliding block used for installing the movable contact set and a second sliding block used for installing the static contact set are arranged in the installation groove, a hinge batten is connected between the upper end of the first sliding block and the lower end of the second sliding block, and a fixing shaft fixedly connected with the base is arranged in the middle of the hinge batten in a clearance and penetrating mode. According to the invention, the ablation time and pull-in and release rebound when the contact resistance tends to zero can be reduced, so that thearc extinguishing speed of the relay can be increased, and the arc extinguishing effect is improved, the creepage distance between the electromagnetic system and the contact system can be increased, so that the electromagnetic relay is suitable for relays with small boundary 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...
