Abstract
The present invention relates to a quick connection electromagnetic relay with a position-limiting convex-arm movable spring eduction piece, which is mainly low in height, small in size and big in power. The present invention comprises a magnetic circuit system, a contact system and a base, and the movable spring eduction piece in a normal open contact type structure is provided with at least one position-limiting convex arm; the movable spring eduction piece is provided with the position-limiting convex arm, so that the spring-back position of the movable spring is accurately limited, and a gap exists between the push block and the movable spring eduction piece of the contact system so as to reduce the initial sucking voltage of the electromagnetic relay and realize quick connection. The quick connection foot of the QC of the electromagnetic relay is educed from the side edge of the housing, so that the whole relay is small in size. After a one-way open slot of the base contains the magnetic circuit, the present invention can effectively enhance insulation performance, which means to increase electrical distance, creepage distance, penetrating insulation distance and isolation degree of the input and the output ends, so that the voltage resistance of the medium is enhanced.
Description
(1) technical field
The present invention relates to a kind of electromagnetic relay, especially a kind of moving spring lead-out tablet of spacing protruding arm of being with that is mainly the small-sized high-power of low clearance connects electromagnetic relay soon.
(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, leading foot generally adopts the PCB mode, the QC of employing connected mode is perhaps arranged, but 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 height, adopting the occasion of fast connected mode, and this series products can't satisfy instructions for use.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 low clearance, simple in structure, assembling, good manufacturability, the small-sized high-power that can carry out streamline production in batches connects electromagnetic relay soon.
It is a kind of high performance that another object of the present invention is to provide, and input, the output dielectric withstanding voltage is more than the 5000Va.c., and its P/C is than being connected electromagnetic relay soon with low clearance that performance/volume ratio all is better than existing like product.
The present invention includes magnetic circuit system, contact system and base, contact system is provided with movable contact spring, moving spring lead-out tablet, static contact spring piece etc., on the moving spring lead-out tablet of normally opened contact type structure, be provided with at least 1 spacing protruding arm, be used to limit the recoil position of movable contact spring, guaranteeing has certain clearance between pushing block and the movable contact spring, with the moving voltage of the initial suction that reduces electromagnetic relay.
Said moving spring lead-out tablet preferably is made as L shaped, and spacing protruding arm is located at one side of L shaped moving spring lead-out tablet.
On base, can establish and the be complementary L groove of clamping of L shaped movable contact spring.
The static contact spring piece of contact system also is L shaped design, its on one side with the L groove coupling clamping of base.
Because moving spring lead-out tablet is provided with spacing protruding arm, has limited the recoil position of movable contact spring exactly, has guaranteed that the pushing block of contact system and moving spring lead-out tablet have certain clearance, thereby voltage is moved in the initial suction that has reduced electromagnetic relay, realizes connecting soon.And the fast connecting pin of the QC of electromagnetic relay is drawn from the shell side, and therefore whole relay volume is less.The unidirectional open slot of base can improve insulation property after containing the magnetic circuit part effectively, promptly increases electrical distance, creepage distance, penetrates insulation distance, improves the isolation of input, output, thereby reaches the purpose that improves dielectric withstanding voltage.

(5) embodiment
As Fig. 1, shown in 2, the present invention includes magnetic circuit system 0, contact system 1 and base 2.Referring to Fig. 3,4, on one side 3.1 of the L shaped moving spring lead-out tablet 3 of the normally opened contact type structure of contact system, be provided with 1 spacing protruding arm 3.2, be used to limit the recoil position of movable contact spring, guaranteeing has certain clearance between pushing block and the movable contact spring 4, with the moving voltage of the initial suction that reduces electromagnetic relay, reach fast purpose of connecting.
On base, can establish and the be complementary L groove 5.1 (referring to Fig. 5) of clamping of L shaped movable contact spring 3.
The static contact spring piece 6 of contact system also is L shaped design, the L groove 5.2 coupling clampings (referring to Fig. 6) of its one side 6.1 and base.
Claims (2)
1, be with the moving spring lead-out tablet of spacing protruding arm to connect electromagnetic relay soon, comprise magnetic circuit system, contact system and base, it is characterized in that on the moving spring lead-out tablet of normally opened contact type structure, being provided with at least 1 spacing protruding arm, moving spring lead-out tablet is made as L shaped, spacing protruding arm is located at one side of L shaped moving spring lead-out tablet, be provided with on base and the be complementary L groove of clamping of L shaped movable contact spring, L shaped movable contact spring is plugged in the L groove on the base.
2, the moving spring lead-out tablet of spacing protruding arm of being with as claimed in claim 1 connects electromagnetic relay soon, the static contact spring piece that it is characterized in that contact system is L shaped design, on base, be provided with and the be complementary L groove of clamping of L shaped static contact spring piece, one side being plugged in the L groove on the base of L shaped static contact spring piece.
