The invention discloses a small electromagnetic relay. The small electromagnetic relay comprises a magnetic circuit system, a contact system, a push block, a cover shell and a base, wherein the base comprises a magnetic circuit system installation portion, a contact system installation portion and an integrally-arranged isolation wall of the relay. The small electromagnetic relay is characterized in that the isolation wall is arranged between the magnetic circuit system and the contact system, a push block slide groove used for installing the push block is arranged on the isolation wall, and a first convex rib and a second convex rib are arranged on the inner side of the top wall of the cover shell; the magnetic circuit system installation portion is provided with a magnetic circuit system slide groove, the contact system installation portion is provided with a contact system slide groove, and the installation slide-in direction of the push block installed in the push block slide groove is mutually parallel to that of the magnetic circuit system installed in the magnetic circuit system slide groove and that of the contact system installed in the contact system slide groove. The relay has the advantages of being simple and fast to assemble, easy to realize automatic production, low in manufacturing cost, good in insulation performance, wide in application range, and more reliable in working.
Description
technical field [0001] The invention relates to a relay, in particular to a small electromagnetic relay. Background technique [0002] A relay is a widely used electronic component, which is used in household appliances, automobiles, industrial control, power systems, communication devices and other fields.
