Description
Technical field
Relay technical field is the utility model is related to, more particularly to a kind of relay with bilateral holding function.
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 can include often
Close quiet spring 107 and normally opened quiet spring 108 (as shown in Figure 1) or only normally opened quiet spring.The relay of this structure, armature
102 be L-type shape, and the bending place of armature 102 coordinates the knife-edge part in yoke 101, the head of armature 102 by stage clip 103
1021 are engaged with the head (being provided with pole shoe) of iron core 105, and the afterbody 1022 of armature 102 is engaged with one end of push card 104,
The other end of push card 104 is engaged with dynamic spring part 106.When applying driving voltage to coil 100, the head of armature 102
1021 close with head (i.e. pole shoe) end face of iron core, and the drive push card 104 of afterbody 1022 of armature 102 is by dynamic spring part 106
Movable contact spring ejected toward the normally opened quiet direction of spring 108 so that the normally opened stationary contact of movable contact and normally opened quiet spring 108 closes.Work as line
