Technical field
The small-sized high-power that the present invention relates to a kind of electromagnetic relay, particularly a kind of low clearance is organized contact AC and DC electromagnetic relay more.
Background technology
Relay is as a kind of electromechanical compo, extensively apply in the various electromechanical equipments, conventional small-sized high-power is organized the AC and DC electromagnetic relay more and is generally comprised coil, coil exit, iron core, yoke, armature, extension spring, moving spring group, moving spring part, static contact spring piece, contact, arc sheet, base, shell.Wherein the dress mode is erected in the general employing of coil, iron core adopts riveting to be connected with yoke, armature and the riveted joint of moving spring group, and be stuck on the yoke, to restore by extension spring, the short transverse size of product is bigger, isolation between coil and contact is also lower, dielectric withstanding voltage is not high, generally speaking between the contact and coil of relay, high energy reaches 1500VAC between contact sets, reaches 1000VAC between the contact.This is requiring the little and input of height installing space, output isolation high field boundary to close with regard to causing, and this series products can't satisfy instructions for use.
In existing alternating current electromagnetic relay, because resetting of armature is general by tension spring tension, yoke, armature all need design the hook of extension spring, with fixedly extension spring, therefore take certain space, caused product size bigger, can't satisfy the little instructions for use in setting height(from bottom) space.
The CN1255232A patent application discloses a kind of relay with contact spring, and relay has electromagnet system and contact arrangement that has at least one quiet contact spring and at least one moving contact spring of a matrix, belt coil, iron core and an armature.The plate that this contact spring makes the plane respectively with do not have permanent bend to approach at identical plane internal fixation in this matrix.This contact spring is realized the closing of contact by the overlap joint of L shaped end section; In addition, quiet contact spring produces pre-stretching by a corresponding backstop on the matrix.The small-sized high-power sensitive-type direct current electromagnetic relay of a kind of Very Low Clearance of CNZL012207489 patent disclosure.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.
The CN1405815A patent application provides a kind of and goes up vertical high isolation of mo(u)ld bottom half, little erection space structure, strength member adopts the variable cross-section design, structure is more compact, the load volume is higher, assembling is adjusted simpler, the more reliable high-isolated vertical miniaturized variable-section high-power electromagnetic relay of working, be provided with electromagnetic system, contact system, carrier part framework, contact part push card and shell, magnetic circuit system is by coil, yoke, armature, stage clip constitutes, contact system is by movable contact spring, the contact, lead-out tablet constitutes, an end that it is characterized in that said push card is provided with platform, be provided with groove and convex tendon in the bottom of platform, and with carrier part framework on corresponding convex tendon that is provided with and groove interlock.
Summary of the invention
The object of the present invention is to provide a kind of low clearance, simple in structure, assembling, good manufacturability, can carry out the production of batch streamline, performance/volume ratio and P/C are organized the AC and DC electromagnetic relay of contact more than the small-sized high-power that all is better than existing similar relay.
Another object of the present invention is to provide a kind of high performance low clearance to organize contact AC and DC electromagnetic relay more, dielectric withstanding voltage can be greater than 2500VAC between its contact and coil, between contact sets, dielectric withstanding voltage can be greater than 1000VAC between the contact, height can reduce 6mm, and its P/C ratio and performance/volume ratio all are better than existing like product.
The present invention includes magnetic circuit system, contact system and base portion, at least 1 group movable contact spring of contact system connects shape in a row (claiming moving spring row) by insulating part, moving spring lead-out tablet is also corresponding to connect shape in a row (claiming moving spring to draw row) by insulating part, and moving spring is drawn and arranged the movable contact spring part that connects to form relay with moving spring row.Moving spring row preferably adopts plastics forming to be structure as a whole, and the bud of establishing on the movable contact spring on the Kong Yudong spring lead-out tablet cooperates riveting to connect.Moving spring is drawn row and is also preferably adopted plastics forming to be structure as a whole, to guarantee the positional precision of the bud on the moving spring lead-out tablet.
Flange is established in both sides in the movable contact spring part, and flange can snap in the set groove of base, is used for the fixing of movable contact spring part.
The L-shaped structure of yoke, armature of said magnetic circuit part is provided with 1 concave station at the iron core end of yoke, is provided with the boss that cooperates with the set concave station of yoke at an end of reset reed, formation magnetic conduction part spacing.Reset reed is provided with 2 symmetric arms, and each arm is provided with 1 hole, armature be provided with reset reed on set corresponding 2 buds in 2 holes, rivet between hole and the bud, so as to armature form spacing with restore.The other end at reset reed is provided with the hangnail that is used to clamp, and hangnail inserts in the seam that forms between bobbin and the yoke.
Because it is spacing that the hangnail effect is carried out, and fixes the armature part.
Owing to avoid using extension spring, therefore do not need the design hook, reduced the height of relay.Magnetic circuit part adopts high isolation design with contact part, electrical distance, creepage distance, penetrates insulation apart from all than original similar relay height, thereby reaches the purpose that improves dielectric withstanding voltage.
Because the movable contact spring of many group contact sets adopts working of plastics to connect the moving spring row of shape, moving spring lead-out tablet also is connected to form moving spring by plastics and draws row, and connects by riveting, avoids adopting the soft wiring soldering of former like product to connect, avoid the pollution in the soldering process, and effectively reduce product cost.
