Abstract

The invention discloses a low height electromagnetic relay which comprises a base, a bobbin wound with enameled wires, an iron core, a yoke, an armature, a compression spring, a moving spring with a pin, a static spring with a pin and a push clamp. The bobbin is horizontally mounted on the base. The yoke is T-shaped and horizontal. The iron core is L-shaped, and the horizontal side of the iron core penetrates in the bobbin. The end surface of the horizontal side of the iron core is a knife edge surface. The vertical side of the iron core is connected with the tail of the yoke. The end surfaceof the head of the yoke is a pole shoe surface. The armature is limited by the compression spring so that the armature is vertical and corresponds to the matching place of the knife edge surface of the iron core and the pole shoe surface of the yoke. The moving spring is provided with a number of curved structures. The initial suction force of the magnetic circuit system is enhanced by utilizing the pole shoe surface of the yoke and the flexibility is enhanced by utilizing a plurality of curved structures of the moving spring so that the low height design of the relay and the two systems reachthe optimal matching state, and the requirement of realizing the small volume of the relay can be met.

Description

technical field [0001] The invention relates to an electromagnetic relay, in particular to a low-height electromagnetic relay. Background technique [0002] With the further miniaturization and intelligentization of products in the fields of home appliances and industrial control, the volume requirements of the internal electronic components are becoming smaller and smaller. As one of the control switching components, the electromagnetic relay has small size, low power consumption, High load will be the future development trend. [0003] However, after the height of the relay is reduced, higher requirements will be placed on the two internal systems. On the one hand, after the height is reduced, the volume of the magnetic circuit system is limited, so the suction force of the product will be reduced, and the product may not be able to pull in or the pull-in voltage is high. On the other hand, after the volume of the contact system is reduced, in order to match the suction ...
