Problems solved by technology

If the drop height is high, the moving reed 511' will undergo plastic deformation. After the impact disappears, the deformation of the moving reed 511' will not recover, and the reaction force of the relay will change. The armature 42' and the yoke 41' will not contact, and the function will be abnormal.

Abstract

The invention discloses an electromagnetic relay with good anti-falling performance. The electromagnetic relay comprises a magnetic circuit part, a contact part, a shell and a base, wherein the magnetic circuit part is horizontally installed on the base and comprises a coil, a yoke, an armature and an iron core; the axis of the iron core is parallel to the board of the base; the contact part comprises a moving spring with moving contacts and a static spring with static contacts; the moving spring is connected between the yoke and the armature in a buckling manner; the yoke and the armature are orthogonally arranged; the moving spring is provided with a first buckling line corresponding to the orthogonal part of the yoke and the armature and a second buckling line sticking to the armature;the moving spring section outside the second buckling line abuts against and is fixed on the armature and forms a moving spring and armature assembly capable of moving with the armature; and limitingconvex plates for limiting the moving spring and armature assembly to move towards the direction far away from the iron core are respectively arranged on the base and on the inner wall of the shell at the side opposite to the base. With the structure, the electromagnetic relay has good anti-falling performance and simultaneously has the characteristics of simple structure, low cost and better manufacturability.

Description

technical field [0001] The invention relates to an electromagnetic relay, in particular to an electromagnetic relay with good drop resistance. Background technique [0002] Electromagnetic relay is an electromechanical component widely used in various automobiles, household appliances, office equipment, and industrial control. Usually it is composed of base, magnetic circuit part, contact part, shell and so on. In order to improve the environmental applicability of the product, relays (especially automotive relays) are required to have better anti-drop performance. [0003] figure 1 It is a structural diagram of an existing electromagnetic relay, which includes a magnetic circuit part 1', a contact part 2', a casing 3' and a base 23'. The magnetic circuit part 1' adopts a horizontal structure, that is, a horizontal magnetic circuit; the horizontal magnetic circuit 1' includes a yoke 11', an armature 12', an iron core 13', a coil 14' and a tension spring 15'. The contact ...
