Speed, so that trigger unit 382 hits the contact part 21 in tripping mechanism 20, makes tripping mechanism 20 thread off close to static iron core 33.
The restorable in the presence of external force of time-delay mechanism 30, the return of time-delay mechanism 30 is dynamic iron core 35 to away from static iron core 33
Direction motion.Dynamic iron core 35 to the direction away from static iron core 33 when being moved, and steel wire will be slided finally along the second lead-in chamfered 372
Move and cross protuberance 37, finally realize return.
In the present embodiment, limiting section is the protuberance 37 located at the outside of dynamic iron core 35, elastic wire 34 and protuberance
Can mutually it be restricted between 37 so that whole time-delay mechanism 30 delay time is longer, delay effect is good.In addition, on protuberance 37
The gradient of first lead-in chamfered 371 is more than the gradient of the second lead-in chamfered 372 so that during 30 return of time-delay mechanism, elastic wire 34
Being capable of easier leap protuberance 37.
Remaining structure of the present embodiment is same as Example 1, will not be repeated here.
The preferred embodiments of the present invention are these are only, are not intended to limit the invention, for those skilled in the art
For member, the present invention can have various modifications and variations.Any modification within the spirit and principles of the invention, being made,
Equivalent, improvement etc., should be included within the scope of the present invention.
