Abstract
The relay is composed of contact system, magnetic system and base. The magnetic system includes yoke, short circuit ring, armature, return spring leaf and winding. The return spring possessing two arms in diglossia structure can be pressed into corresponding two grooves on the yoke. Stable electric parameters of the relay are insured since the compressing diglossia structure and limited apex of the tongue of return spring leaf. The relay has no spring part, making volume of magnetic system become smaller so as to guarantee miniaturized relay. Unidirectional open slot on the base containing part of magnetic circuit provides good performances: raised insulation property, electrical distance, creepage distance and penetrating through insulation distance. Through experiment, both of creepage distance and spacing interval is larger than 10 mm. Isolation between input end and output end is raised so as to increase withstand voltage of medium. The withstand voltage reaches 5000 Va.c.
Description
(1) technical field
The present invention relates to a kind of electromagnetic relay, especially a kind of small-sized high-power hum bar two tongue reset reed electromagnetic relay that is mainly low clearance.
(2) background technology
Electromagnetic relay extensively applies in the various electromechanical equipments as a kind of electromechanical compo.Existing conventional small-sized high-power alternating current electromagnetic relay generally comprises coil, coil exit, iron core, yoke, armature, spring, pushing block, movable contact spring, static contact spring piece, contact, base, shell.Wherein coil generally adopts the formal dress mode, iron core adopts riveting to be connected with yoke, holding in the mouth 1 iron is stuck on the yoke, restore by spring, the short transverse size of product is bigger, and the isolation between coil and contact is also lower, and dielectric withstanding voltage is not high, the high energy of the product of transfer contact type generally speaking reaches 3000Va.c., and normally opened contact type product also can only reach 4000Va.c..This just causes requiring installing space little, and input, output isolation high occasion, reaches series products and can't satisfy instructions for use.
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 object of the present invention 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 object of the present invention 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 present invention 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 present invention includes parts such as contact system, magnetic circuit system, base, wherein magnetic circuit system is made up of yoke, short-circuited conducting sleeve, armature, reset reed and coil etc., said reset reed is provided with 2 arms, be the two tongue structure and be pressed into corresponding 2 grooves or limiting stand on the yoke, to limit the tongue end of reset reed, guarantee 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.
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.
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.
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..
