Abstract
The invention relates to a relay, especially an electromagnetic relay with movable reed having good flexibility. Invented relay consists of magnetic circuit part, driving clip, contacting part, shell and bottom seat. The contacting part includes parts of static reed and movable reed. The contacting part connects to the magnetic circuit part by using the driving clip. The movable reed possesses a knee bend with U shape in same direction as the driving direction of the driving clip. The knee bend with U shape lengthens the working length of the movable reed so that it provides better flexibility than the flexibility of L type reed and plain piece type reed. The upper static reed is in L type fixed on the bottom seat, providing good positioning and stability under high temperature. The heave of armature iron matches with the inclined plane of the driving clip, used to localize the two parts so as to reduce the difficulty for producing these two parts. The magnetic circuit part can be composed of U shaped yoke iron, coil and armature iron, also it can be composed of iron core by rivet jointed and yoke iron or coil and armature iron.
Description
(1) technical field
The present invention relates to a kind of electromagnetic relay, especially a kind of electromagnetic relay with well flexible moving reed.
(2) background technology
Electromagnetic relay is a kind of electromechanical compo that is widely used in various household electrical appliance, office equipment, Industry Control.Usually it is made up of contact system, magnetic circuit system, shell and base portion.Product requirement its moving spring little, highly sensitive for volume has good flexibility.
The contact system of existing a kind of small-sized high-power electromagnetic relay (see figure 1) comprises static contact spring piece 11, the flexible movable contact spring 12 of fluting.Movable contact spring 12 is a plain film, has groove along its length.Magnetic circuit system is made up of U-shaped yoke 13, coil 14, armature 15 and making leaf spring 16.Other is provided with pushing block 17, base 18.
Another kind of small high-power relay (see figure 2) by normally closed static contact spring piece part 28, often open static contact spring piece part 29, movable contact spring part 19, yoke 20, coil 21, armature 22, making leaf spring 23, base 24, pushing block 25, moving spring and draw weld tabs 26, shell and coil and draw weld tabs 27 and form.Often open static contact spring piece part 29 for L shaped, rely on the L profile to cooperate with base 24, plastics are softening under the high temperature, easily cause the reed change in location.Armature 22 and pushing block 25 cooperate with inclined-plane on the pushing block 25 by the skewed slot on the armature 22, and part processing is difficult, easily causes the working of plastics fracture during assembling.
As everyone knows, the flexibility of moving spring is very big to the sensitivity influence of electromagnetic relay, yet the miniaturization of electromagnetic relay is the inexorable trend of its development, in more and more littler space, under the situation that the electromagnetic relay technology has become ripe, the competition of the ratio of performance to price gets over acutely, and it improves and also becomes more and more difficult.
(3) summary of the invention
The object of the present invention is to provide and a kind ofly have well flexible moving reed so that it is easy to process, sensitivity big, the electromagnetic relay of stable performance.
The present invention is made up of magnetic circuit part, push card, contact portion, shell and base.Contact site sets up quiet spring part, moving spring part separately, and contact portion is connected by push card with the magnetic circuit part, and moving spring has the U-shaped bending identical with the push card pushing direction, to improve the flexibility of moving spring.The bending of said moving spring U-shaped specifically can be designed to
Or analogous shape.
The magnetic circuit part of relay can be designed to horizontal, and the cavity of a horizontal direction opening is arranged on base, and magnetic circuit partly inserts the cavity of base.Along with development of science and technology, electromagnetic relay especially volume is little, the extensive more and urgent need of the application of highly sensitive big or middle power miniature electro-magnetic relay, yet electromagnetic relay is a very ripe industry, and the structure of movable contact spring and performance are very big to parameter influences such as the volume of electromagnetic relay and sensitivity.Because moving spring of the present invention has the U-shaped bending identical with the push card pushing direction, the active length of moving spring has extended, and adopt the design of above-mentioned different shape, therefore have than existing various types of moving springs, for example the moving spring of Chang Yong plain film is better flexible, and the sensitivity that has improved relay significantly also can be dwindled its volume, and easy to process, reduced product cost.In addition, upper electrostatic spring is L shaped, except that utilizing profile and base cooperates, also utilizes breach to cooperate with the convex tendon of base, is fixed in base, and its positioning action ratio only depends on profile to have good positioning, and is at high temperature more stable.The projection of armature cooperates with the push card inclined-plane, is used for the mutual location of two parts, reduces the part manufacture difficulty.The magnetic circuit part can be made up of U-shaped yoke, coil, armature, also can be made up of riveting iron core, yoke assembly and coil, armature together.

As shown in Figure 3, the present invention is by quiet spring part 1, upper electrostatic spring part 2, moving spring part 3, push card 4, armature 5, coil 6, stage clip 7, lead-out wires of coil 8, yoke 9, base 10 and shell etc. are formed down.Quiet spring part 1, upper electrostatic spring part 2, moving spring part 3 are inserted in the groove of base 10 down, form contact portion.Upper electrostatic spring part 2 is made up of upper electrostatic spring 2.1, fixed contact 2.2.Moving spring part 3 is made up of moving spring 3.1, moving spring bracket 3.2, moving contact 3.3.Moving spring 3.1 is the U-shaped bending identical with push card 4 pushing directions, for
Or analogous shape, to improve the flexibility of moving spring.U-shaped yoke 9 (also can be L shaped yoke with unshakable in one's determination combination) is formed the magnetic circuit parts with coil 6, armature 5, stage clip 7, partly pack into the die cavity 10.1 towards the horizontal direction opening of base 10 of magnetic circuit.The magnetic circuit part is connected by push card 4 with contact portion.When the relay adhesive, armature 5 moves to yoke 9 directions, drives push card 4 and moves, and makes moving spring 3.1 rotate, and realizes the switching of contact, and the relay dispose procedure in contrast.
Shown in Fig. 3,4,8,9, the column part 4.1 of push card 4 passes the hole 3.1.1 of moving spring 3.1, and push card 4 utilizes inclined-plane 4.2 to cooperate with the projection 5.1 of armature 5, makes push card reliably to locate.
