Abstract
The utility model provides a kind of microswitch structure, relates to the field such as electronic device, medical device, is related specifically to a kind of microswitch structure.Comprise the button, spring, shell fragment, normally open contact, normally closed interlock and the common contact that arrange in base, base, shell fragment described in described spring one end connects, described shell fragment is between described normally closed interlock and normally open contact, the other end of described spring is fixed on described common contact, described button is against described spring, it is characterized in that, one cavity volume is set in described base, arrange a diode in described cavity volume, these diode two ends are connected with common contact and normally closed interlock respectively.The utility model by arranging a cavity volume, diode-built-in on base, and reduce the external space that takies and machining period, after overall package, the performance of this sensitive switch is good.
Description
Technical field
The utility model relates to the field such as electronic device, medical device, is related specifically to a kind of microswitch structure.
Background technology
Sensitive switch is applied in as electric pushrod, computer mouse, automobile Genius mouse, automobile electronics, communication apparatus, war products, tester, gas heater, gas range, small household appliances, microwave oven, electric rice cooker, ball float coordinative composition of equipments, medicine equipment, building automatic, electric tool and generally electric and wireless device, 24 hours timers etc., there is small contact separation and quick-acting mechanism, the contact mechanism of switch motion is carried out with the stroke specified and power, covered by shell, there is driver its outside, and profile is less.But the inside of existing sensitive switch encapsulation, it only has some mechanical part interior, and it needs external diode or other circuit, reaches protection or realizes electrical behavior switch state, this external circuit or diode, takes up room large, consuming time many.
Utility model content
The technical problem to be solved in the present invention is to provide a kind of micro-switch structure, its simple structure, takes up room little, inside connects diode, compact conformation, and encapsulation is simple.
Be achieved through the following technical solutions above-mentioned purpose:
A kind of microswitch structure, comprise the button, spring, shell fragment, normally open contact, normally closed interlock and the common contact that arrange in base, base, shell fragment described in described spring one end connects, described shell fragment is between described normally closed interlock and normally open contact, the other end of described spring is fixed on described common contact, described button is against described spring, one cavity volume is set in described base, arrange a diode in described cavity volume, these diode two ends are connected with common contact and normally closed interlock respectively.
Preferably, row is held in described common contact and the pull-out of normally closed interlock level with both hands, and is separately positioned on the side of described base.
Preferably, described common contact and the pull-out end of normally closed interlock arrange the recess of a symmetry respectively.
Preferably, described cavity volume is arranged at below described spring.
Preferably, described base is also provided with fixed leg between normally open contact, normally closed interlock.
The beneficial effects of the utility model are: the utility model is passing through rationally to arrange all parts on base, the cavity volume of one placement diode is set, realize diode-built-in, this diode is serially connected in the middle of the loop that normally closed interlock is connected with common contact, use as switch, built-in diode is arranged on base compactly, does not take redundant space.
Accompanying drawing explanation
Fig. 1 is explosive view of the present utility model;
Fig. 2 is the explosive view adopting another form diode;
Fig. 3 is the profile that Fig. 1 is corresponding;
Fig. 4 is the profile that Fig. 2 is corresponding.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described:
The direction term mentioned in following examples, such as " upper and lower, left and right " are only the directions with reference to accompanying drawing, and therefore, the direction term of use is used to illustrate and is not used for limiting the utility model.
As shown in figures 1-4, a kind of microswitch structure, comprise base 1, the button 8 arranged in base, spring 5, shell fragment 6, normally open contact 3, normally closed interlock 2 and common contact 4, shell fragment 6 described in described spring 5 one end connects, described shell fragment 6 is between described normally closed interlock 2 and normally open contact 3, the other end of described spring 5 is fixed on described common contact 4, preferably, spring 5 horizontal positioned, described button 8 is from being positioned at top against described spring 5, a shell fragment 6 is fixed in the right of spring 5, when button 8 is pressed time, spring 5 is with spring plate 6 to be connected with normally open contact 3 instantaneously downwards, when spring 5 resets time, spring 5 is with spring plate 6 to be upwards connected with normally closed interlock 2 instantaneously.The left of spring 5 arranges common contact 4, and the pull-out end of common contact 4 is vertical with spring 5.Row is held in described common contact 4 and the pull-out of normally closed interlock 2 level with both hands, and is separately positioned on the side of described base.
One cavity volume 11 is set in described base, this cavity volume 11 the pull-out end of common contact 4 and normally open contact 3 pull out hold between and be positioned at below spring 5, arrange a diode 7 in described cavity volume 11, these diode 7 two ends are connected with common contact 4 and normally closed interlock 2 respectively.
Described common contact 4 and the pull-out end of normally closed interlock 2 arrange the recess 21,41 of a symmetry respectively.This recess 21,41 places two links of diode 7, guarantees normal connection.
Described base 1 is also provided with fixed leg 9 between normally open contact 3, normally closed interlock 2, in order to strengthen the overall and outside fixed effect of sensitive switch further.
The utility model is passing through rationally to arrange all parts on base, the cavity volume 11 of one placement diode 7 is set, realize diode-built-in 7, this diode 7 is serially connected in the middle of the loop that normally closed interlock 2 is connected with common contact 4, use as switch, built-in diode 7 is arranged on base compactly, does not take redundant space.
The above not imposes any restrictions this novel technical scope, all above embodiment is done according to the utility model technical spirit any amendment, equivalent variations and modification, all still belong in the scope of this novel technical scheme.
