Abstract
The utility model relates to a switch, in particular to quick switching, little differential micro -gap switch. Technical scheme does: a quick switching, little differential micro -gap switch, the rocker switch structure comprises a housing, a button, locate the static contact of normally opening in the shell, normal close static contact and movable contact spare, movable contact spare is the strip body, movable contact spare including banding driving body and on locating the driving body and can with the contact of normally opening static contact and the quiet male contact of normal close, be equipped with the support that supplies movable contact spare to erect in the shell, it is parallel form with the normal close static contact and erects in the shell to normally open the static contact, the contact of movable contact spare extends to to be normally opened between static contact and the normal close static contact, it contradicts with the support to be equipped with one end on the support, the elasticity return spare of the driving body conflict of the other end and movable contact spare. Adopt above -mentioned technical scheme, provide that a conversion rate is fast, the deviation can have appeared during the conversion, made that circuit connection is stable, simple structure's quick switching, little differential micro -gap switch.
Description
Technical field
The utility model relates to a kind of switch, particularly a kind of rapid translating, little differential sensitive switch.
Background technology
Sensitive switch has small contact clearance and snap-action mechanism, carries out the contact mechanism of switch motion with the stroke specified and specified force.
Traditional sensitive switch is primarily of shell, button, be located in shell often open fixed contact, normally closed fixed contact and driven by button can with the movable contact piece often opening fixed contact or normally closed fixed contact and contact conducting, movable contact piece is plates, and it extends to the one end of often opening fixed contact and normally closed fixed contact place and is provided with moving contact.
Movable contact piece by after button press with often open fixed contact and fit, impel switch to be unlatching conducting state, and button releasing is to after the compressing of movable contact piece, movable contact piece then can contact and the laminating of often holding fixed contact, otherwise can keep fitting by elastic force and normally closed fixed contact.Usual movable contact piece is flexure strip, but after using for a long time, its elastic sensitivity can reduce, movable contact spring is in often open to occur between fixed contact and normally closed fixed contact changing situation about slowly maybe cannot change, and movable contact spring and often to open stroke between fixed contact and normally closed fixed contact longer in traditional sensitive switch, in use easily occur larger differential.
Summary of the invention
For the deficiency that prior art exists, the utility model provides that a kind of conversion speed is fast, conversion time there will not be deviation, make the simple rapid translating of circuit stable connection, structure, little differential sensitive switch.
For achieving the above object, the utility model provides following technical scheme: a kind of rapid translating, little differential sensitive switch, include shell, button, be located at and often open fixed contact in shell, normally closed fixed contact and driven by button can with the movable contact piece often opening fixed contact or normally closed fixed contact and contact conducting, movable contact piece is strip shape body, movable contact piece includes the driving body of strip and to be located on driving body and can with the contact often opened fixed contact and normally closed fixed contact and contact, the support for movable contact piece erection is provided with in shell, it is characterized in that: described often open fixed contact and normally closed fixed contact is that parallel shape is set up in shell, the contact of movable contact piece extends to often to be opened between fixed contact and normally closed fixed contact, support is provided with one end and support is conflicted, the elastic recoil part that the driving body of the other end and movable contact piece is conflicted.
Adopt technique scheme, often open fixed contact and normally closed fixed contact is that parallel shape is set up in shell, its spacing is little, on movable contact piece, the amplitude of fluctuation of moving contact when impelling circuit communication or cutting off diminishes, and stroke shortens, and stability is in use guaranteed, embody the little differential feature of this sensitive switch, the another elastic recoil part arranged for implementing to conflict to touch part on support, impels the conversion speed of movable contact piece faster, and more stable.
The utility model is set to further: elastic recoil part comprises the shell fragment with two elasticity conflict ends, two elasticity of shell fragment are conflicted to hold and are connected by cambered surface, support is positioned at one of them elasticity conflict end place of shell fragment and is provided with the spacing breach placed for this elasticity conflict end, another elasticity conflict end of shell fragment and the driving body of movable contact piece are conflicted.
Adopt technique scheme, arrange structure so simple, the large and elastic force of elastic force is not easily lost, long service life.
The utility model is further set to: one end that button and touch part are conflicted is that triangular shape is arranged.
Adopt technique scheme, when setting makes button implement to conflict to touch part like this, touch part can be implemented to swing fast, for the conversion speed increasing movable contact piece provides advantage.
Below in conjunction with accompanying drawing, the utility model is further described.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
A kind of rapid translating as shown in Figure 1, little differential sensitive switch, include shell 1, button 2, be located at and often open fixed contact 3 in shell 1, normally closed fixed contact 4 and driven by button 2 can with the movable contact piece 5 often opening fixed contact 3 or normally closed fixed contact 4 and contact conducting, movable contact piece 5 is strip shape body, movable contact piece 5 includes the driving body 51 of strip and to be located on driving body 51 and can with the contact 52 often opened fixed contact 3 and normally closed fixed contact 4 and contact, the support 6 set up for movable contact piece 5 is provided with in shell 1, often opening fixed contact 3 is set up in shell 1 with normally closed fixed contact 4 in parallel shape, the contact 52 of movable contact piece 5 extends to often to be opened between fixed contact 3 and normally closed fixed contact 4, support 6 is provided with one end and support 6 is conflicted, the elastic recoil part 7 that the driving body 51 of the other end and movable contact piece 5 is conflicted.In such scheme, often opening fixed contact 3 is set up in shell 1 with normally closed fixed contact 4 in parallel shape, its spacing is little, on movable contact piece 5, the amplitude of fluctuation of moving contact 52 when impelling circuit communication or cutting off diminishes, and stroke shortens, and stability is in use guaranteed, embody the little differential feature of this sensitive switch, the another elastic recoil part 7 arranged for implementing to conflict to touch part 5 on the frame 6, impels the conversion speed of movable contact piece 5 faster, and more stable.
In the utility model embodiment, elastic recoil part 7 comprises the shell fragment with two elasticity conflict ends 71, two elasticity conflict ends 71 of shell fragment are connected by cambered surface 72, support 6 is positioned at one of them elasticity conflict end 71 place of shell fragment and is provided with the spacing breach 61 placed for this elasticity conflict end 71, another elasticity conflict end 71 of shell fragment is conflicted with the driving body 51 of movable contact piece 5.Certainly, it should be noted that, elastic recoil part 7 also can be the spring be located between touch part 5 driving body 51 and button 2, and just its installation process is comparatively loaded down with trivial details, and elastic force cannot be guaranteed, therefore the utility model preferably the former.
In order to further improve the conversion speed of sensitive switch in the utility model embodiment, one end that button 2 and touch part 5 are conflicted is that triangular shape is arranged.Certainly, also can be arc-shaped and arrange, implement point-to-point compressing and both can.
