Problems solved by technology

[0003] A magnetic circuit system in the prior art is a horizontal electromagnetic relay. The coil frame of the magnetic circuit system only relies on the coil lead-out terminal installed at one end of the axial direction to be inserted into the base to achieve unilateral fixation. During impact vibration, the other axial end of the coil frame will float, resulting in product parameter changes and failure

Abstract

The invention discloses an anti-impact electromagnetic relay. The electromagnetic relay comprises a base, a magnetic circuit part and a contact part, the magnetic circuit part is horizontal and comprises a yoke, an armature, an iron core, a coil rack arranged on the base and an enameled wire arranged on the coil rack, and two coil leading-out terminals electrically connected with the enameled wireare arranged at one axial end of the coil rack and penetrate through the base respectively; the other axial end of the coil rack is provided with a first fixing part facing the base, and the first fixing part is fixedly connected with the base. After the coil rack is provided with the first fixing part, when the coil rack is impacted and vibrated, the other axial end of the coil rack cannot float, so that the mechanical stability of a magnetic circuit part is improved, and the stability and reliability of product parameters are improved.

Description

technical field [0001] The invention relates to the field of relays, in particular to an impact-resistant electromagnetic relay. Background technique [0002] The relay is an electronic control device, usually used in automatic control circuits, it is actually a kind of "automatic switch" that uses a small current to control a large current. Therefore, it plays the role of automatic adjustment, safety protection, and conversion circuit in the circuit. The mechanical stability of the magnetic circuit system inside the relay is crucial to the stability and reliability of product parameters. [0003] A magnetic circuit system in the prior art is a horizontal electromagnetic relay. The coil frame of the magnetic circuit system only relies on the coil lead-out terminal installed at one end of the axial direction to be inserted into the base to achieve unilateral fixation. When shocking and vibrating, the other axial end of the bobbin will float, resulting in product parameter c...
