Base device of small-sized electromagnetic relay

The utility model provides a base device of a small-sized electromagnetic relay. The base device comprises a base, a static reed, a static contact which is fixedly riveted on the static reed, and a connecting piece. The base comprises an inner surface N and an outer surface W. A first limiting block is arranged on the static reed. A transparent assembly hole is arranged in the base. The static reed on which the static contact is fixedly riveted is inserted into the assembly hole from the inner surface N to the outside, and is fixedly connected with the base. Through the fixed connection, the static contact is located on the side of the inner surface N. The first limiting block contacts and matches the base on the inner surface N. Through the contact matching, the static reed is prevented from playing along the insertion direction F. In a production line, automatic contact riveting and automatic static reed inserting are realized, which can improve the assembly automation of the small-sized electromagnetic relay, the production efficiency, the riveting quality and the qualified rate of finished products. The labor and the product production cost are reduced.
