Abstract
This utility model relates to a mini-electromagnetic AC relay of low-height and high-power, with a double-tongued return spring. This device comprises a housing, a magnetic circuit system, a contacting system, and a base. The magnetic circuit system is provided with a yoke, a short-circuit ring, an armature, a return spring, and a coil, wherein two arms of a double-tongued structure are arranged on the return spring and pressed into the two concave slots or spacing platforms on the yoke. One end of the armature is provided at least two fixed concave slots for the double-tongued ends and convex edge for spacing of the armature. The yoke and the armature forms an integrating structure and the yoke is of ''U'' shape, in whose slots the short-circuit ring is arranged. The two slots on the end of the yoke are for the two edges of the short-circuit ring. The magnetic circuit system is arranged in the single-side open sealed cavity on the base, being located on the convex of the yoke. The adoption of a double-tongued pressure structure and restriction of tongue ends of the return spring together insure stability of the electric parameters of the relay. Absence of spring components makes the magnetic system and the relay a smaller volume.

In existing alternating current electromagnetic relay, the general spring tension that passes through that resets of armature is a fulcrum with the yoke, seesaw type structure in the formation, and the magnetic circuit volume is bigger, causes product size bigger, can't satisfy the little instructions for use in setting height(from bottom) space.The CN2472340Y patent disclosure a kind of small-sized high-power sensitive-type direct current electromagnetic relay of Very Low Clearance, mainly form by contact system, magnetic circuit system, base and shell.Contact system comprises static contact spring piece, U-shaped movable contact spring, and inserts in the base by the guide groove on the base, and the U-shaped press-bending position of movable contact spring is inserted the base guide groove and fixed.Magnetic circuit system is packed in the cavity on the base, locatees in the base guide groove, and some glue is fixed.
(3) summary of the invention
The purpose of this utility model is to provide a kind of electric parameter stable, low clearance, simple in structure, assembling, good manufacturability can be carried out the production of batch flowing water, and performance, volume ratio and performance, price are than the small-sized high-power alternating current electromagnetic relay that all is better than existing similar relay.
Another purpose of the present utility model is to provide a kind of high performance low clearance alternating current electromagnetic relay, input, output dielectric withstanding voltage are greater than 5000Va.c., dielectric withstanding voltage is greater than 2500Va.c. between two groups of contacts, and it is low to exchange the magnetic circuit height, can satisfy user's requirement low to setting height(from bottom).
To achieve these goals, the utility model adopts two tongue compression type reset reed structure to the reed of magnetic circuit system, and limits the position of its tongue end, and is stable with the electric parameter of guaranteeing electromagnetic relay.
The utility model comprises contact system, magnetic circuit system, base and shell, and wherein contact system is provided with static contact spring piece and movable contact spring, and is located on the guide groove of base; Magnetic circuit system is provided with yoke, short-circuited conducting sleeve, armature, reset reed and coil, and is located in the cavity on the base, is fixed on the base.Said reset reed is provided with 2 arms, is the two tongue structure and is pressed into corresponding 2 grooves or limiting stand on the yoke, to limit the tongue end of reset reed, guarantees that the electric parameter of electromagnetic relay is stable.One end of armature is provided with at least 2 reset reed tongue end fixed grooves, and is provided with the flange that is used for limiting position of armature.Armature places a side of bobbin, flange armature rotating support, and flange is used for the spacing of armature.The yoke and the armature of magnetic circuit system are integrative-structure, the yoke structure that takes the shape of the letter U, and short-circuited conducting sleeve places the open slot of U-shaped yoke end, and U-shaped yoke end is provided with 2 grooves, is used to clamp 2 limits of short-circuited conducting sleeve.Magnetic circuit system is located in the closed cavity of the single face opening on the base, is positioned the protruding bud on the yoke.And by the some glue with magnetic circuit partial fixings such as bobbins in base portion.
Said reset reed can be L-shaped, on one side it is provided with at least 2 tongue ends, another side is provided with tears lug boss, and the chucking that is used on bobbin is fixed.One side of the bobbin of said coil is provided with and is used to support and the spacing flange of holding in the mouth the position.
Owing to adopt two tongue compression type reset reed structure, and define the tongue end of reset reed, guaranteed that therefore the electric parameter of electromagnetic relay is stable.Owing to avoided the use spring members, therefore make the volume of magnetic circuit system become less in addition, the overall volume of electromagnetic relay is also obviously dwindled, for the miniaturization of electromagnetic relay is given security.Simultaneously, after the unidirectional open slot of base has contained the magnetic circuit part, can improve its insulation property effectively, promptly increase electrical distance, creepage distance, penetrated insulation distance, through test, creepage distance and spacing have improved the isolation of input and output all greater than 10mm, thereby reached the purpose that improves dielectric withstanding voltage, dielectric withstanding voltage can reach 5000Va.c..
