Abstract

The invention discloses a relay assembly with an arc extinguishing function. The relay assembly comprises a contact bin, an insulating support, a movable iron core, a push rod, two static contacts, a movable contact plate, an arc striking angle, a main spring, magnetic steel and an arc extinguishing gate, the insulating support is arranged at the bottom of the contact bin, a cavity is arranged in a combination body of the contact bin and the insulating support, the static contacts are fixed on the contact bin, the upper ends of the static contacts are located above the contact bin, the lower ends of the static contacts are located in the cavity, the movable iron core is arranged below the insulating support, the push rod is fixed on the movable iron core, a through hole allowing the push rod to enter and exit is formed in the bottom of the insulating support, and the push rod extends into the cavity from the through hole. According to the invention, the arc striking angle, the magnetic steel and the arc chute are matched, so that the relay assembly has double arc extinguishing effects of magnetic quenching and arc chute quenching, the arc extinguishing effect is more ideal, the relay is not easy to damage, and the safe use of the relay is ensured.

Description

【Technical field】 [0001] The invention relates to the technical field of relays, in particular to the technical field of relay components. 【Background technique】 [0002] There are often static contacts and moving contacts on the relay. When the moving contacts and static contacts are in contact or separated, arcs are likely to occur. contacts, but also bring certain security risks. 【Content of invention】 [0003] The purpose of the present invention is to solve the problems in the prior art, and propose a relay assembly with arc extinguishing function, which can make the relay assembly have a good arc extinguishing effect. [0004] In order to achieve the above purpose, the present invention proposes a relay assembly with arc extinguishing function, which includes a contact chamber, an insulating support, a moving iron core, a push rod, a static contact, a moving contact plate, an arc striking angle, a main spring, Magnetic steel, arc extinguishing grid, an insulating s...
