Magnetic latching relay is the automatic switch element for having isolation features, be widely used in remote control, remote measurement, communication, from It is one of most important control element, magnetic latching relay does not have at present in dynamic control, electromechanical integration and power electronic equipment Heat sinking function, it is impossible to worked in hygrothermal environment, decay resistance is poor, it is impossible to carries out circuit protection.It is therefore, it is proposed that a kind of High-temp resistant type magnetic latching relay.
【Utility model content】
Main purpose of the present utility model is to provide a kind of high-temp resistant type magnetic latching relay, passes through small-sized heat radiating fan Magnetic latching relay is radiated, avoids temperature is too high from influenceing relay work, can be absorbed by drier in relay Moisture, by protective cover can magnetic latching relay there is high temperature resistant and decay resistance, pass through resettable fuse Circuit can be protected, effectively can solved the problems, such as in background technology.
To achieve the above object, the technical scheme that the utility model is taken is:
A kind of high-temp resistant type magnetic latching relay, including protective cover and set casing, magnetic is installed with the set casing Guard relay body and resettable fuse, the resettable fuse is arranged on magnetic latching relay body side, described Protective cover inside bottom is provided with damping spring, and described damping spring one end is connected with set casing bottom, one in the protective cover Side is provided with drier, is provided with small-sized heat radiating fan at the top of the protective cover, the protective cover side is provided with temperature controller, institute State and basic unit is provided with protective cover, the basic unit lower surface is provided with high-temperature-resistant layer, is provided with below the high-temperature-resistant layer acidproof Alkali layer.
Further, protective cover and the set casing both sides are provided with threading hole.
Further, the temperature controller and small-sized heat radiating fan are electrical connected, the resettable fuse and magnetic keep after Electrical equipment body is electrical connected.
Further, the acid and alkali-resistance layer is prepared by epoxide resin material, and the high-temperature-resistant layer is by glass fiber material system It is standby.
Compared with prior art, the utility model has the advantages that:Can be to circuit by resettable fuse Shield, when circuit overload, at this moment resettable fuse is in high resistant guard mode, and the increase of impedance limits electricity Stream, electric current drastically decline within a very short time, and so as to which protection circuit equipment is against damages, resettable fuse can after failture evacuation To recover automatically, the vibrations of magnetic latching relay body can be slowed down by damping spring, enable relay be arranged on vibrations compared with Used in big equipment, start small-sized heat radiating fan when temperature is higher than temperature controller setting value and radiated, avoid temperature too high Magnetic latching relay job stability is influenceed, drier can remove the moisture in containment vessel, avoid circuit from making moist short circuit, pass through The high-temperature-resistant layer set on protective cover can make magnetic latching relay have stronger resistance to elevated temperatures, can be set installed in high temperature Standby upper use, acid and alkali-resistance layer can avoid magnetic latching relay from being corroded in acid or alkali environment, adapt to a variety of environment and use.
