Abstract
This utility model relates to a mini-electromagnetic relay of low-height and high-power, with quick connection of a spacing convex arm of a lead-out moving spring. This device comprises a magnetic circuit system, a contacting system, and a base. At least one spacing convex arm is arranged on the lead-out moving spring of the contacting system. The spacing convex arm equipped on the lead-out moving spring accurately limits rebound position of the moving spring, insuring that certain space exists between the push block and the lead-out moving spring, and thereby decreasing initial operating voltage of the electromagnetic relay and realizing quick connection. After connection of the foot of an external QC terminal with the side of the housing of the electromagnetic relay, the whole relay is in a small volume. Containment of the magnetic circuit within the one-way slot on the base can effectively improve insulating property, which is an increase of electric distance, creepage distance, penetrating insulation distance, and isolation of input and output terminals from other media, enhancing pressure resistance.
Description
(1) technical field
The utility model relates to a kind of electromagnetic relay, and 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 purpose of this utility model is to provide a kind of low clearance, simple in structure, assembling, good manufacturability, and the small-sized high-power that can carry out streamline production in batches connects electromagnetic relay soon.
Another purpose of the utility model is to provide a kind of high performance, 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 utility model comprises 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 utility model comprises 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.
