Problems solved by technology
The base structure of this electromagnetic relay makes the isolation between the magnetic circuit part and the dynamic and static spring part, between the moving spring part and the static spring part insufficient. On the one hand, during the use of the relay, contact spatter will fall on these areas. This leads to a decrease in the insulation capacity of the product, or even breakdown failure; on the other hand, the structure of these areas is thin (influenced by the slots of the side-mounted dynamic and static springs), and in high-temperature environments, the base is prone to warping and deformation, thereby reducing the parameter stability of the relay , reducing the electrical life of the relay

The invention discloses a high temperature-resistant relay base structure. The high temperature-resistant relay base structure comprises a base body; one end of the base body is provided with a firsthalf frame structure for mounting a magnetic circuit portion; insertion slots into which a movable reed portion and a fixed reed portion can be laterally mounted are formed at the other end of the base body; and the base body is provided with a first full frame structure arranged at a position between the insertion slots of the movable reed portion and the fixed reed portion. With the high temperature-resistant relay base structure of the invention adopted, the degree of isolation between the magnetic circuit portion of a relay and the movable and fixed reed portion can be increased; the deformation resistance of the base at a high temperature can be enhanced; and therefore, the use performance of the relay can be improved.
Description
technical field [0001] The invention relates to the technical field of relays, in particular to a high temperature resistant relay base structure. Background technique [0002] Electromagnetic relay is a kind of control element, which is widely used in home appliances, industrial control equipment and other fields. Electromagnetic relays in the prior art usually include a magnetic circuit part, a base, a moving spring part, a static spring part and a push block, wherein the moving spring part includes a moving reed and a moving contact, and the static spring part includes a static reed and a static contact , The magnetic circuit part is installed or inverted on the base. A kind of electromagnetic relay of the prior art, its moving spring part and static spring part are both loaded into the base from the side, and the suction force generated by the magnetic circuit part pushes the spring part through the pushing block, so that the moving contact and static spring part of the...
