Description
Technical field
The utility model relates to microswitch fields, and in particular to a kind of silent micro switch.
Background technique
Microswitch is that have small contact separation and snap-action mechanism, and it is dynamic to carry out switch with defined stroke and defined power
The contact mechanism of work, is covered with shell, outside have a kind of switch of drive rod because contact spacing of its switch is smaller,
Therefore named microswitch, is called sensitive switch.
A kind of terminal portion structure of microswitch is disclosed in patent CN201721675463.3.This microswitch is pressed
Casting die is located above the crossbeam portion of movable contact spring, has apparent contact to hit sound after pressing, and sound is larger when use, ten partial volumes
Easily bother the people of surrounding.
Utility model content
Pass through and nothing in view of the above-mentioned problems, the utility model is intended to provide a kind of electric current that can satisfy 0.1A-10.1A
The silent micro switch of sound.
To realize that the technical purpose, the embodiment of the utility model be: a kind of silent micro switch, including movable contact spring, upper end
Son, lower terminal, common terminal, pressing piece, pedestal, the pedestal pass through integrated injection molding and upper terminal, lower terminal, common end
The middle part of son, which is molded, to be fixed, and the upside down place of the upper terminal is provided with upper contact, and place is set upward for the upper end of the lower terminal
It is equipped with lower contact, described movable contact spring one end is fixed on common terminal upper end by buckle structure, and the movable contact spring other end is located at
Between upper contact and lower contact；
The movable contact spring includes crossbeam portion, shrapnel part, contact portion, and the crossbeam portion buckle is mounted on common terminal side
End, the shrapnel part buckle are mounted on common terminal other side upper end, and the contact site is between upper contact and lower contact；
Shell is set on the pedestal, pressing piece is nested on the shell, the pressing piece is being located at shrapnel part just
Top.
Preferably, being also movably installed with press handle above the shell, the press handle is located above pressing piece.
The beneficial effects of the utility model, the application reset the position of pressing piece, and pressing piece is being located at shrapnel part just
Top is equal to and changes switching mode, to generate noiseless effect；The application, can relative to traditional clip type press-key structure
Enough electric currents by 0.1A-10.1A, are also able to achieve voiceless sound.
Detailed description of the invention
The cross-sectional view of Fig. 1 the utility model；
The explosive view of Fig. 2 the utility model；
The partial structural diagram of Fig. 3 the utility model.
Specific embodiment
The utility model is described in further details in the following with reference to the drawings and specific embodiments.
As shown in Figure 1-3, specific embodiment described in the utility model be a kind of silent micro switch, including movable contact spring 4,
Upper terminal 3, lower terminal 2, common terminal 1, pressing piece 6, pedestal 5, the pedestal 5 by integrated injection molding and upper terminal 3, under
The middle part injection molding of terminal 2, common terminal 1 is fixed, and the upside down place of the upper terminal 3 is provided with upper contact 7, the lower terminal
Place is provided with lower contact 8 upward for 2 upper end, and described 4 one end of movable contact spring is fixed on common 1 upper end of terminal, institute by buckle structure
4 other end of movable contact spring is stated between upper contact 7 and lower contact 8；
The movable contact spring 4 includes crossbeam portion 401, shrapnel part 402, contact portion 403,401 right-hand end of the crossbeam portion buckle
It is mounted on common 1 side upper end of terminal, the buckle of shrapnel part 402 is mounted on common 1 other side upper end of terminal, the contact
Portion 403 is between upper contact 7 and lower contact 8；
Shell 9 is set on the pedestal 5, is nested pressing piece 6 on the shell 9, the pressing piece 6 is located at elastic slice
Right above portion 402.
In order to more accurately and conveniently be pressed into pressing piece, 9 top of shell is also movably installed with press handle 10,
The press handle 9 is located at 6 top of pressing piece.Pressing section can be increased by press handle, it conveniently at an arbitrary position can be effective
Pressing piece is touched, realizes preferably pressing effect.
General switch press crossbeam position can generate switching, there is apparent contact shock sound, and the application is by pressing piece
Position is reset, and pressing piece is located at right above shrapnel part, is equal to and is changed switching mode, to generate noiseless effect；
The structure of switch contact conducting has obvious switching sound substantially, and does not just have sound using clip type, but
It is the electric current that cannot be loaded beyond 1A of intermediate plate mode, the structure of the application can either also can by the electric current of 0.1A-10.1A
Realize voiceless sound.
The above, the only preferred embodiment of the utility model, are not intended to limit the utility model, all according to this
The technical spirit of utility model any trickle amendment, equivalent replacement and improvement to the above embodiments should be included in this
Within the protection scope of utility model technical solution.
