Description
Technical field
The utility model belongs to switch, is specifically related to a kind of sensitive switch.
Background technology
Sensitive switch is to have small contact separation and fast actuation mechanism, and the contact mechanism that carries out switch motion by stroke and the power of regulation, because of the less therefore named sensitive switch of its switch contact spacing, is again sensitive switch.Sensitive switch is widely used in the electric equipments such as computer mouse, vehicle electronics, communication apparatus, tester, small household appliances.Existing sensitive switch has fixing triggering stroke conventionally, can not meet under different operating modes triggering the demand of stroke.
Utility model content
(1) technical problem that will solve
The technical problems to be solved in the utility model is to provide a kind of simple in structure, and volume is small and exquisite and and can adjust the sensitive switch that triggers stroke.
(2) technical scheme
For solving the problems of the technologies described above, the utility model provides a kind of sensitive switch, comprises shell, upper cover, and described upper cover and shell are realized embedding by the groove of the projection that covers on being arranged on and corresponding setting on shell and be connected; On described, cover and be provided with through hole, described through hole and button are connected; The end of described button contacts with movable contact spring, and the left end of described movable contact spring is fixedly connected with shell by screw, and the right-hand member of described movable contact spring is provided with moving contact; The bottom of described shell is provided with a counter sink, and described counter sink internal thread is connected with bolt, and the top of described bolt contacts with movable contact spring.
Wherein, the diameter of the end of described button is greater than the diameter on button top.
Wherein, the left end of described movable contact spring is connected with pin, and described pin is fixed on described shell.
Wherein, be also provided with static contact on described shell, one end of described static contact is provided with fixed contact, described fixed contact be positioned at moving contact under.
Wherein, the end of described button comprises a protruding curved portions.
(3) beneficial effect
Compared with prior art, the utlity model has simple in structurely, the feature such as volume is small and exquisite, and can regulate the triggering stroke of sensitive switch, meets the user demand of different operating modes.
Accompanying drawing explanation
Structural representation when Fig. 1 is the less stroke of the utility model sensitive switch.
Structural representation when Fig. 2 is the larger stroke of the utility model sensitive switch.
Fig. 3 is the partial enlarged drawing of the utility model sensitive switch A portion.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but can not be used for limiting scope of the present utility model.
The structure of the utility model sensitive switch as Figure 1-3, comprise shell 1, upper cover 2, described upper cover 2 and shell 1 are realized embedding and are connected by being arranged on the groove of projection 201 on upper cover 2 and corresponding setting on shell 1, adopt embedded connection can make upper cover 2 and shell 1 realize being connected faster, and there is higher connection reliability; On described upper cover 2, be provided with through hole 202, described through hole 202 is connected with button 3; The end 301 of described button 3 contacts with movable contact spring 4, and the left end of described movable contact spring 4 is fixedly connected with shell 1 by screw 401, and the right-hand member of described movable contact spring 4 is provided with moving contact 402; The bottom of described shell 1 is provided with a counter sink 101, and described counter sink 101 internal threads are connected with bolt 6, and the top of described bolt 6 contacts with movable contact spring 4.
As optimization, the diameter of the end 301 of described button 3 is greater than the diameter on button 3 tops, and the therefore displacement of energy limit button 3 in the vertical directions prevents that button 3 from departing from upper covers 2.
As optimization, the left end of described movable contact spring 4 is connected with pin 8, and described pin 8 is fixed on described shell 1.
As optimization, on described shell 1, be also provided with static contact 7, one end of described static contact 7 is provided with fixed contact 701, described fixed contact 701 be positioned at moving contact 402 under.
As optimization, the end 301 of described button 3 comprises a protruding curved portions, described button 3 contacts by curved portions with movable contact spring 4, can make the relative sliding between button 3 ends 301 and movable contact spring 4 more level and smooth, prevents that the motion causing because local pressure is excessive is obstructed.
During use, button 3 moves downward under pressure, and shift knob 3 is in the process moving downward, 301 pairs of movable contact springs 4 of end face on button 3 are exerted pressure, make movable contact spring 4 that elastic deformation occur, finally make joint on moving contact 402 and fixed contact 701, realize circuit communication.During active force on withdrawing button 3, movable contact spring 4 restores to the original state under the effect of self elastic force, drives button 4 to move up simultaneously.
In the time of need to changing the triggering stroke of sensitive switch, bolt 6 is screwed in shell 1, under the effect of bolt 6, the initial deformation amount of movable contact spring 4 increases, and the spacing of 701 of moving contact 402 and fixed contacts is increased, and then realize the object that changes triggering stroke.
These are only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
