Abstract
The miniaturized great-power electromagnetic relay includes magnetic path system, contact system, base seat, pushing clamp and casing. Partition wall on the base seat separates the space to right and left variable-section cavities, one holding magnetic path system and the other holding the contact system. The armature acts via the pushing slot on the partition wall and is linked by the pushing clamp to moving reed to push the reed for contact conversion. Reasonable space distribution results in small volume, compact structure and high isoaltion degree. The parts are assembled via inserting and this is simple and favorable to mass production.
Description
The present invention relates to a kind of electromagnetic relay, especially a kind of carrier part framework adopts the miniaturized variable-section high-power electromagnetic relay of right and left variable-section cavities design.

Corresponding partition wall cooperation on middle partition wall and the shell, the relay inner space is divided into the cavity of two high isolation, before the relay sheath body, the cavity of dress magnetic circuit system and contact system all opens wide, compare with existing relay, the not assembling of instrument part, adjust more conveniently, quick, be very beneficial for realizing that automation produces in enormous quantities continuously; And current capacity after enough length spaces and height space are guaranteed the flexible and load raising of movable contact spring arranged.
Adopt the horizontal high low clearance structure of isolating, can guarantee that coil has enough coiling window space, effectively improves sensitivity; The location of magnetic circuit system is adopted and designed the self-align boss that cooperates with the base location on yoke, and whole magnetic circuit system and contact system are accurately located, and has simplified the assembly technology device effectively, has improved assembly precision; Designed the limiting position of armature structure on the base, within the limits prescribed with the moving qualification of the string of armature on the edge of a knife.
The section cavities of the dress magnetic circuit system that base and shell constitute, the end that the cross section is big is guaranteed to promote the rotation space of armature movable contact spring and realize conversion.Corresponding with dress magnetic circuit system one end, the heavy in section cavity is distributed to the contact system of contact system, switches space requirement thereby satisfied the contact.
A side of system is touched in the base attaching, be provided with the hole of inserting dynamic and static contact lead-out tablet, direct fixing lead-out tablet, compare with known plastic hot riveting fixation, the anti-intensity that plugs and unplugs that connects (QC) leading foot fast effectively improves, and has saved the expense of rivet hot equipment and operation, has reduced the complexity coefficient of lead-out tablet processing of dynamic and static contact and assembling simultaneously, and having improved the utilance of lead-out tablet material, is that automated production lays the foundation when reducing part manufacturing cost.
On the correspondence position of base and shell partition wall, be provided with the promotion groove, corresponding with the variable cross-section armature arm, the variable cross-section push card of packing into, magnetic circuit system and contact system that height is isolated connect.
Push card is provided with the boss of pack into armature and promotion groove, pack into and be provided with the distortion slot to make way in the middle of the boss of armature, set up defences and withdraw from buckle in the side, push card is provided with the enough big platform of an area in the moving spring position of promotion, guarantees to satisfy the space and the creepage distance requirement of the requirement of VDE reinforced insulation.
Armature is movably connected on the variable cross-section yoke by stage clip, and the limiting stand on the base satisfies the reliable and stable work of energy under strong vibration, the impact condition with the moving qualification of the string of armature on the edge of a knife within the limits prescribed.
Partition wall on base of the present invention and the shell, with two section cavities of relay internal insulation for dress magnetic circuit system and contact system, the action of armature is connected by the movable contact spring of push card with itself and contact system by the promotion groove on the partition wall, promotes the switching that movable contact spring is realized the contact.By rational allocation of space, make relay littler at volume, highly lower, satisfied the high insulation request of VDE safety certification in the time of more compact structure.Adopt between parts to clamp the location and be connected, make assembling simpler, locate more accurately, be beneficial to continuous production in enormous quantities.
