Specific embodiment
To keep the above objects, features, and advantages of the utility model more obvious and easy to understand, with reference to the accompanying drawing to this
The specific embodiment of utility model is described in detail.Many details are explained in the following description in order to abundant
Understand the utility model.But the utility model can be implemented with being much different from other way described herein, this field
Technical staff can do similar improvement without prejudice to the utility model connotation, therefore the utility model is not by following public affairs
The limitation for the specific embodiment opened.
As shown in Figs 1-4, the utility model provides a kind of chip touch-switch, and the chip touch-switch includes:
Metal clips 1 is directly integrally formed by punching press, and 1 surrounding of the metal clips level is intermediate to arch upward；And
Pad 2 is arranged at four angles of the metal clips 1, and the pad 1 passes through electronic welding technique hand
Section is welded on circuit board, forms first electrode；
The metal clips 1, by arched part and the contact point contact on circuit board, forms the second electricity by pressed by external force
Pole, first electrode and second electrode are connected to form closed circuit, switching function conducting.
Specifically, the word explanation of switch is to open and close.It also refers to that one can make open circuit, make in electric current
Break or it is made to flow to the electronic component of other circuits.It is most common switch be allow people operate electromechanical equipment, wherein have one or
Several electronic contacts." closure " (the c l osed) of contact indicates electronic contact conducting, and electric current is allowed to flow through；" open circuit " of switch
(open) it indicates that electronic contact is not turned on to form open circuit, does not allow electric current to flow through.The conducting reliability crucial effect of touch-switch
Factor is the structure of elastic slice contact point, because the function of touch-switch is that circuit board contact pad and elastic slice carry out contact conducting, that
The contact surface of elastic slice contact point is the bigger the better, and contact surface is determined by structure, and the present embodiment is in order to guarantee to be connected to greatest extent
Reliability uses four pads together with welding circuit board, and inside region of arching upward may be incorporated for and circuit board contacts
Point contact.When needing using switching function, region of arching upward is pressed, makes arch upward region and circuit board contacts point contact, forms one
A closed circuit, so that closing the switch conducting.After cancelling pressure, metal clips 1 is sprung back, and arch upward region and circuit board disconnection company
It connects, switch disconnects.Such design, so that the present embodiment direct-assembling uses on circuit boards, assembling is extremely simple to the greatest extent, required
Material also greatly reduces, and the production time is greatly saved and has saved cost, stability and consistency but greatly improve.
In some embodiments, which is characterized in that 1 cross section of metal clips is in square.
In some embodiments, the metal clips 1 is equipped with the arc-shaped through-hole 3 for preventing the pad from loosening,
Its inside that pad 2 is set.
In some embodiments, there are four the arc-shaped through-hole 3 is set.
Specifically, arc-shaped through-hole 3 can be applied directly to pad 2 when applying pressure to arched part to avoid pressure
On, 2 two sides of capable past pad are transmitted, pad 2 is avoided to loosen.
In conclusion the utility model includes metal clips 1, directly it is integrally formed by punching press, the metal clips 1
It arches upward among surrounding is horizontal；And pad 2, it is arranged at four angles of the metal clips 1, the pad 1 passes through
Electronic welding process means are welded on circuit board, form first electrode；The metal clips 1 will be arched upward portion by pressed by external force
Point with the contact point contact on circuit board, form second electrode, first electrode connects to form closed circuit with second electrode, switch
Function conducting.Using the above design, touch-switch can be made not need multiple component assemblings, material and production time is saved, mention
High efficiency and stability.
Above-described embodiments merely represent several embodiments of the utility model, the description thereof is more specific and detailed,
But it cannot be understood as the limitations to utility model patent range.It should be pointed out that for the common skill of this field
For art personnel, without departing from the concept of the premise utility, various modifications and improvements can be made, these are belonged to
