Description
Technical field
The utility model relates to the relay class of electromechanical compo, particularly high-power sealed electromagnetic relay.
Background technology
The operation principle of electromagnetic relay is: after coil electricity, iron core is magnetized and produces enough large electromagnetic force, inhale moving armature and drive in the middle of reed, make that reed and normally-closed contact separate, and normally opened contact closure; After coil blackout, electromagnetic attraction disappears, and armature returns to original position, the state that moving contact returns to original closure or separates.
Common electromagnetic relay can not be taken into account on environmental index and load capacity simultaneously, and reliability is low.
Summary of the invention
Provided by the utility model a kind ofly have two groups of double make contacts, switch load electric current and reach 40A, environmental index is high, reliability is high high-power sealed electromagnetic relay.
Formation of the present utility model: a kind of high-power sealed electromagnetic relay, partly formed by contact system, magnetic circuit system and case, it is characterized in that: in the case part, contact system and magnetic circuit system are housed, contact system mainly is made of base, contact, static contact spring piece, splitter and movable contact spring, and magnetic circuit system mainly is made of yoke, coil, iron core, holder part, armature part and magnet steel; The contact of contact system, splitter riveting are contained on movable contact spring, and static contact spring piece, movable contact spring soldering are on base; The yoke of magnetic circuit system, coil, iron core and holder part riveting are fitted together, and armature partly is locked in rotating shaft, and the magnet steel soldering is on support; The rotating shaft riveting of holder part is contained on support; The pusher section point of armature part is welded on support chip, and the support chip point is welded on armature; Contact system connects together by spot welding with magnetic circuit system, and the case part encapsulates by melting welding.
Compared with the prior art, characteristics of the present utility model are to use the two air gap contact portions of bridge-type, and the ability of cut-offfing the high-energy direct-current arc is improved greatly; Middle reed uses the high-performance elastic alloy, has high conductance and temperature tolerance; The silver-base alloy contact that cut-offs the direct-current arc excellent performance is used in the contact; The rotary armature of rotating mechanism balance has good anti-vibration, shock resistance; Shell uses metal cap shell melting weldering sealing, the inner protective gas of filling, and steam vent uses the steel ball spot welding seal, has guaranteed the reliability of working under the low pressure.
The beneficial effects of the utility model:
The switch load volume ratio is large, anti-vibrating and impact, serviceability temperature wide ranges, is specially adapted to switch in Aeronautics and Astronautics electronic instrument, equipment the circuit of large electric current.
