A miniature bridge type sealed DC (Direct Current) electromagnetic relay with double air gap structures consists of contact part, an electromagnetic part and an enclosure. The electromagnetic part (1) is fixed in a groove corresponding to the contact part (2) through electric resistance welding; a relay part (3) is sealed with the enclosure (4) through laser welding; the contact part consists of a base, movable reels, a stationary contact, a stationary reel, a shunting piece and a stationary contact; the movable contact (7) is connected with the movable reel (6) through riveting process to form movable reel parts; the shunting piece (9) is used for connecting the two movable reel parts through riveting processing to form a movable reel assembly; the stationary contact (10) is connected with the stationary reel (8) through riveting process to form a stationary reel part; the movable reel assembly and the stationary reel part are welded on the base through soldering welding process, and jointly form the contact part; and the two movable reel parts are connected through the shunting piece to form the group of movable reel assembly which is welded on the base, thus forming a double-air gap structure of the contact. The electromagnetic relay is large in load switching ability and strong in process operability and applicability and can work under severe environments.
Description
technical field [0001] The invention relates to a relay, in particular to a small bridge type double air gap structure sealed DC electromagnetic relay. Background technique: [0002] Relays are divided into miniature relays, ultra-small relays and small relays according to different dimensions, and are divided into low-power relays, medium-power relays and high-power relays according to different load powers. This type of relay belongs to high-power small relays. The ability of the relay contact to switch the load has a certain range. If it exceeds the specified range, the relay will be damaged or the switching will be unreliable. The ability of relay contacts to switch loads is usually restricted by the external dimensions. The larger the external dimensions, the greater the ability to switch loads, but this is contrary to the requirements of some special users. In some special occasions, users want small external dimensions but The ability to switch loads is large. Ther...
