Description
Technical field
The present invention relates to a kind of noise-damping bowl and noise reducing type relay thereof.
Background technology
In the prior art, it is usually present a movable part and moves to a fixed component and the structure that contacts, work as work
Collision when dynamic component contacts with fixed component will make a noise, this noise can affect user use product time perceived quality under
Fall.Such as, in relay, relay is generally made up of magnetic circuit system, contact system, pushing portion and installation extension,
Wherein magnetic circuit system mainly converts electrical energy into mechanical energy and drives pushing portion motion, makes contact system contact, thus reaches out
The effect closed.The mechanical movement that magnetic circuit system therein produces when electric energy is converted into mechanical energy makes pushing portion (movable part)
Motion, so that the sound closing of contact (disconnection).The many groups of movable parts contacted and fixed component is deposited in relay,
Such as when the actuating of relay, movable contact (being equivalent to movable part) and stationary contact (being equivalent to fixed component) is just had to contact,
Dynamic iron core (being equivalent to movable part) and static iron core (being equivalent to fixed component) contact, and when relay discharges, just have
Pushing portion (being equivalent to movable part) contacts with static iron core or yoke (being equivalent to fixed component), and dynamic iron core (is equivalent to
Movable part) and iron core mounting seat (being equivalent to fixed component) contact, these contact be likely to produce noise.In order to
Reducing noise, prior art is typically with the noise-damping bowl of a flat bowl structure and is arranged between movable part and fixed component, comes
As the buffer unit between movable part and fixed component, this structure is produced impulsive force energy during collision, only
Can be deformed by compression bolster and extend buffer time, and the displacement for solid deformation generation is the most limited, therefore,
The time of impact moment is the least so that the instant impact of collision is very big, thus, this noise-damping bowl of prior art, it disappears
Except noise result is poor, however it remains bigger noise.
Summary of the invention
It is an object of the invention to overcome the deficiency of prior art, it is provided that a kind of noise-damping bowl and noise reducing type relay thereof, by right
