Description
Technical field
The present invention relates to relay technical field, more particularly to a kind of power is electrically isolated and is easy to implement Automated assembly
Relay.
Background technology
Relay is a kind of automatic switch element with isolation features, and it is widely used in household electrical appliances, remote control, remote measurement, logical
Interrogate, automatically control, in electromechanical integration and power electronic equipment, being one of most important control element, risen in control circuit
Automatically adjust, safeguard protection, the effect such as change-over circuit.
Fig. 1 is a kind of conventional relay construction of prior art, and the relay includes coil 100, yoke 101, armature
102nd, stage clip 103, push card 104, iron core 105, dynamic spring part 106 and quiet spring part, wherein, quiet spring part includes normally closed quiet
Spring 107 and normally opened quiet spring 108, naturally it is also possible to be only normally opened quiet spring.The relay of this structure, armature 102 is L-type shape
Shape, the bending place of armature 102 coordinates the knife-edge part in yoke 101, head 1021 and the iron core 105 of armature 102 by stage clip 103
Head (be provided with pole shoe) be engaged, the afterbody 1022 of armature 102 is engaged with one end of push card 104, push card 104 it is another
One end is engaged with dynamic spring part 106.When applying driving voltage to coil 100, the head 1021 of armature 102 and the head of iron core
(i.e. pole shoe) end face is closed, and the afterbody 1022 of armature 102 drives push card 104 by the movable contact spring of dynamic spring part 106 toward normally opened quiet
The direction of spring 108 is ejected, so that the normally opened stationary contact of movable contact and normally opened quiet spring 108 is closed.When the voltage of coil 100 is removed,
Utilize the mechanical counter-force of the recovery of movable contact spring so that the normally opened stationary contact point of the movable contact and normally opened quiet spring 108 of dynamic spring part 106
Disconnected, finally movable contact moves to the normally closed stationary contact end of normally closed quiet spring 107 in the presence of movable contact spring restores mechanical counter-force, and normal
Close stationary contact and realize closure.The relay of this structure, (is exported in coil magnetic circuit part (i.e. importation) with contact part
Part) between be provided with push card 104 (push card is working of plastics), for by the strong power part (output par, c) of relay with it is weak
(importation) is completely isolated for electric part comes, the air gap and insulation of increase relay importation and output par, c away from
From so that relay can reach the safety index required by relevant criterion, while the motion of armature of relay part is transmitted
Onto movable contact spring part, contact is set to realize closure；Due to push card 104 will mounted in armature 102 afterbody 1022 and movable contact spring it
Between, thus automatic assembling can not be realized, moreover, the assembling of whole magnetic circuit part is not also convenient.
