Problems solved by technology

Because the armature needs to move for a long time, if the armature is not set properly, it is easy to cause problems such as unsmooth movement, offset fulcrum, wrong contact, resulting in unstable electrical parameters, etc., resulting in a decline in the seismic performance of the product and unreliable mechanical structure.

Abstract

The invention relates to an electromagnetic relay comprising a substrate. An electromagnet unit, a plugging board, a movable terminal and a fixed terminal are arrayed on the substrate parallelly; the electromagnet unit comprises a yoke and a coil fixed to the yoke; an armature is provided with a rotary shaft inside and is fixed to the yoke through the rotary shaft; the plugging board is fixed to the substrate in a swinging manner and comprises a first terminal and a second terminal, the first terminal contacts with the armature, and the second terminal contacts with the movable terminal; the movable terminal contacts with the fixed terminal. The electromagnet unit generates magnetic force after being powered on to drive the armature to rotate around the rotary shaft and perform mechanical actions, the second terminal of the plugging board contacts with the movable terminal to drive the movable terminal to contact with the fixed terminal, and the circuit is conductive. The armature adopts the fixed rotary shaft as a supporting point, and the transmission force reduction caused by the armature position displacement can be avoided during rotation.

Description

technical field [0001] The invention relates to an electromagnetic relay. Background technique [0002] Electromagnetic relays generally include bus bars, which are used to connect connectors and electronic components. In the field of electromagnetic relay use, the electromagnetic system of most electromagnetic relays is composed of coils, yokes, armatures and other parts. The two ends of the coil are connected with voltage to generate electromagnetic field and magnetic flux, and finally the system armature makes the electromagnetic relay produce mechanical action. . Because the armature needs to operate for a long time, if the armature is not set properly, it is easy to cause problems such as unsmooth movement, offset fulcrum, wrong contact, resulting in unstable electrical parameters, which will cause problems such as the decline in the seismic performance of the product and the unreliability of the mechanical structure. Contents of the invention [0003] In order to s...
