Description
Technical field
It the utility model is related to a kind of shock resistance microswitch.
Background technology
Microswitch is also known as sensitive switch, has the characteristics that to be active in one's movements, parameters precision is high, small volume, is made extensively
In electronic instrument and meter and electrical equipment.At present, most of microswitch impact resistances are weak on domestic market, no
The environment requirement of weaponry can be met, high impact-resistance switch can only pass through external import
Utility model content
In order to solve the above technical problems, the utility model provides a kind of shock resistance microswitch, the shock resistance fine motion is opened
Pass can expand use range, increase the diversification of environmental suitability, and small volume, easy to operate, reliability is high, realize anti-powerful
Impact.
The utility model is achieved by the following technical programs.
A kind of shock resistance microswitch provided by the utility model, including movable contact spring, locator card, electric-conductor；It is described dynamic tactile
Piece interrupted midway position is stuck in the middle part of locator card, and movable contact spring both ends stress is crimped on electric-conductor, and movable contact spring center is upward
Projection, correspond to and be provided with locator card moving up and down on the position that movable contact spring raises up；The electric-conductor is two difference
The both ends installation of corresponding movable contact spring is fixed, and electric-conductor electrically connects with movable contact spring；Movable contact spring center interposition is equipped with interruption.
Movable contact spring center bottom position, which is set, vertically has stage clip.
The locator card is fixed on button center bottom.
The electric-conductor is fixed in pedestal, and button is stuck in pedestal center tip position.
The position that the movable contact spring center raises up is stuck in locator card.
The button is stuck in pedestal by neck, and can be moved up and down.
The beneficial effects of the utility model are：Use range can be expanded, increase the diversification of environmental suitability, volume
It is small, easy to operate, reliability is high, realize anti-strong impact.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure：1- movable contact springs, 2- locator cards, 3- buttons, 4- pedestals, 5- electric-conductors, 6- stage clips.
Embodiment
Be described further below the technical solution of the utility model, but claimed scope be not limited to it is described.
A kind of shock resistance microswitch as shown in Figure 1, including movable contact spring 1, locator card 2, electric-conductor 5；The movable contact spring 1
Interrupted midway position is stuck in the middle part of locator card, and movable contact spring (1) both ends stress is crimped on electric-conductor (5), the center of movable contact spring 1
Raise up, locator card 2 moving up and down is provided with the position that corresponding movable contact spring 1 raises up；The electric-conductor 5 is two
The individual both ends installation for corresponding to movable contact spring 1 respectively is fixed, and electric-conductor 5 electrically connects with movable contact spring 1；The movable contact spring 1 hits exactly centre
There is interruption position.
The movable contact spring 1, which hits exactly bottom position and set, vertically has stage clip 6.
The locator card 2 is fixed on button 3 and hits exactly bottom.
The electric-conductor 5 is fixed in pedestal 4, and button 3 is stuck in pedestal 4 and hits exactly tip position.
The movable contact spring 1 hits exactly the position to raise up and is stuck in locator card 2.
The button 3 is stuck in pedestal 4 by neck, and can be moved up and down.
Thus, by pressing keys 3, promote locator card 2 to move down, strut the " u "-shaped position of movable contact spring 1, so as to send out
Raw elastic deformation, produces elastic force, when locator card 2 is moved to commutation critical point, the elastic energy of " u "-shaped position storage in flat reed
Abrupt release is measured, switch is commutated, realizes the forward conversion of switch.When external force eliminates, locator card 2, movable contact spring 1 are in the bullet of stage clip 6
Automatically reset in the presence of power, complete one-off circulation.The utility model mechanism is designed using " u "-shaped reed-type, locator card 2
Cooperation with movable contact spring 1 is by " convex " shape step in the middle part of movable contact spring and the checkpost position of locating groove four, after movable contact spring component deformation
Extruding to middle (locating groove), the firm screens in the presence of movable contact spring component deformation power, switch is using stage clip compression bullet
Power resets.Compared with the prior art, the utility model is simple in construction, contact is reliable, has anti-strong impact (20000g) ability,
The harsh use environment requirement of weaponry can be met.
