Abstract
The utility model provides a kind of thin film switch precisely turned on, belongs to membrane switch technology field.It solves the technical problems such as existing switch key sensitivity is relatively low, the reliability of conducting is poor.A kind of thin film switch precisely turned on, including circuit board and reed, there is contact on circuit board, reed is located at the top of contact, and a boss is provided between reed and contact, and boss is made up of conductive material, boss turns on contact, and boss is rectangular close to the one side of reed.The utility model has high reliability.
Description
Technical field
The utility model belongs to membrane switch technology field, is related to a kind of thin film switch precisely turned on.
Background technology
Although can feel that shell fragment is pressed on finger when shell fragment is pressed, under partial picture, distance that shell fragment pushes
Also it is not enough to and contact admittance, so that keypress function is not realized, i.e. invalid operation；
Invalid operation, which is gap of the contact between shell fragment, pushes that pretightning force as contact is uncoordinated to be led with shell fragment
Cause, user has used the lower pressure for thinking triggering contact enough, but does not reach the depression distance of anticipation.
The use of this invalid operation electron electrical equipment brings potential safety hazard, even if there is the prompting of keypad tone, can not expire
Sufficient demand for security.
Also a kind of situation, pressure is excessive under user, causes circuit board where contact to be deformed, or even for a long time
Extruding causes it impaired.
Utility model content
The purpose of this utility model is to be directed to above mentioned problem existing for existing technology, there is provided a kind of film precisely turned on
Switch, technical problem to be solved in the utility model are how to improve sensitivity and the reliability of button conducting.
The purpose of this utility model can be realized by following technical proposal：A kind of thin film switch precisely turned on, including
Circuit board and reed, there is contact on the circuit board, the reed is located at the top of contact, it is characterised in that the reed
A boss is provided between contact, the boss is made up of conductive material, and the boss turns on the contact, the boss
One side close to reed is rectangular.
Boss can reduce the distance between reed and contact, make button sensitiveer.
The presence of boss, the triggering distance that reed pushes can be reduced, avoid invalid operation.
Boss is rectangular surfaces close to the side of reed, and gabarit is prismatic, more effective, relatively reliable can be led with reed
It is logical.
As another technical solution, in a kind of above-mentioned thin film switch precisely turned on, the middle part tool of the reed
There is a contact site stretched out to boss direction.
The contact site can further strengthen the reliability of contact, improve keystroke sensitivity.
In a kind of above-mentioned thin film switch precisely turned on, the both ends of the contact site have a limiting section respectively,
The limiting section and trigger unit are the laminated structure being formed integrally.
When reed presses to a certain degree, mutually extruding, limitation reed continues to push two limiting sections, so as to circuit
Plate is protected, and extends the service life of thin film switch and place circuit board.
In a kind of above-mentioned thin film switch precisely turned on, the boss is made up of copper material.
Compared with prior art, the utility model has advantages below：
1st, boss can reduce the distance between reed and contact, make button sensitiveer；The presence of boss, it can reduce
The triggering distance that reed pushes, avoids invalid operation；Boss is rectangular surfaces close to the side of reed, and gabarit is prismatic, Neng Gougeng
Effectively, it is relatively reliable to be turned on reed.
2nd, when reed presses to a certain degree, mutually extruding, limitation reed continues to push two limiting sections, so as to electricity
Road plate is protected, and extends the service life of thin film switch and place circuit board.
Brief description of the drawings
Fig. 1 is the overall structure diagram of this thin film switch in embodiment one.
Fig. 2 is the overall structure diagram of this thin film switch in embodiment two.
In figure, 1, circuit board；11st, contact；2nd, reed；21st, contact site；22nd, limiting section；3rd, boss.
Embodiment
It is specific embodiment of the utility model and with reference to accompanying drawing below, the technical solution of the utility model is made further
Description, but the utility model is not limited to these embodiments.
As shown in figure 1, this thin film switch precisely turned on includes circuit board 1 and reed 2, there is contact 11 on circuit board 1,
Reed 2 is located at the top of contact 11, and a boss 3 is provided between reed 2 and contact 11, and boss 3 is made up of conductive material, boss
3 turn on contact 11, and boss 3 is rectangular close to the one side of reed 2；Boss 3 can reduce between reed 2 and contact 11 away from
From making button sensitiveer；The presence of boss 3, the triggering distance that reed 2 pushes can be reduced, avoid invalid operation；Boss 3
Side close to reed 2 is rectangular surfaces, and gabarit is prismatic, more effective, relatively reliable can be turned on reed 2；Boss 3 is
Copper material is made.
Embodiment two
The content of the present embodiment is substantially identical with embodiment one, except that：
As shown in Fig. 2 the middle part of reed 2 has a contact site 21 stretched out to the direction of boss 3；The contact site 21 can
The reliability of further enhancing contact, improves keystroke sensitivity；The both ends of contact site 21 have a limiting section 22 respectively, limit
Position portion 22 and trigger unit are the laminated structure being formed integrally；Two limiting sections 22 mutually squeeze when reed 2 presses to a certain degree
Pressure, limitation reed 2 continues to push, and so as to being protected to circuit board 1, extend thin film switch and place circuit board 1 uses the longevity
Life.
Specific embodiment described herein is only to the utility model spirit explanation for example.The utility model institute
Category those skilled in the art can make various modifications or supplement to described specific embodiment or using similar
Mode substitute, but without departing from spirit of the present utility model or surmount scope defined in appended claims.
Although the arts such as circuit board 1, contact 11, reed 2, contact site 21, limiting section 22, boss 3 have more been used herein
Language, but it is not precluded from the possibility using other terms.It is used for the purpose of more easily describing and explaining this using these terms
The essence of utility model；Any additional limitation is construed as all to disagree with the utility model spirit.
