Description
Technical field
The present invention relates to a kind of button and comprise its mobile terminal.
Background technology
DOME sheet, i.e. metal clips conducting film (Metaldomearray/DomeArray), for modal DOME sheet, it is one piece of thin slice comprising metal clips, according to pad locations corresponding on wiring board to arrange the position of each metal clips, and other components and parts arrange corresponding clearance position and location hole etc.DOME sheet is used in PCB(printed circuit board) or the wiring board such as flexible circuit board (i.e. FPC) on use as switch, between user and instrument, play the effect of an important sense of touch type switch.Compared with traditional silica gel push-button, DOME sheet has better feel, longer life-span, also indirectly can improve the production efficiency of all types of switches using conducting film.Operation principle on DOME sheet is exactly the conducting position (major part is positioned at above the golden finger on wiring board) that metal clips is positioned on wiring board, when being subject to pressing, the central point of shell fragment is recessed, touch the circuit on wiring board, thus formation loop, electric current passes through, and whole product is just able to normal work.
The button of current product, generally presses DOME sheet by pressing piece, makes shell fragment recessed, for this reason, the press surface of pressing piece can be provided with protuberance, removes contact DOME sheet by the protuberance of correspondence.When user presses, the sense of touch depressed by shell fragment can learn whether pressing operation completes, in order to avoid press more.But in fact, because DOME sheet is fixed and reason such as pressing piece assembling tolerance etc., easily cause protuberance and DOME center to produce eccentric phenomena, thus have impact on the pressing feel of user, even cause pressing less than DOME, cause button malfunction.
Summary of the invention
The technical problem to be solved in the present invention is not good in order to overcome prior art handfeel of keys, easily malfunctioning, causes the defect of misoperation, provides a kind of button and comprises its mobile terminal.
The present invention solves above-mentioned technical problem by following technical proposals:
A kind of button, comprise at least one pressing piece, at least one DOME sheet, its feature is, described button also comprises wiring board and insulating blanket, described DOME sheet is arranged between described wiring board and described insulating blanket, wherein, described insulating blanket is provided with protuberance, the quantity of described protuberance is identical with the quantity of described DOME sheet, and each described protruding parts is in the center of the described DOME sheet of correspondence.Protuberance is arranged on after on insulating blanket, and its position is in the center position of DOME sheet all the time, the impact that can not be assembled, and after pressing piece pressing, protuberance can be made to be pressed into DOME sheet.Wiring board can according to circumstances select PCB(printed circuit board) or FPC(flexible PCB) etc.Insulating blanket and protuberance all adopt electrical insulating material, avoid producing interference.
Preferably, described insulating blanket comprises at least one fixed groove, and described fixed groove is for holding each described DOME sheet.Fixed groove forms a cavity, makes DOME sheet be contained in fixed groove, and the sidewall of fixed groove then constrains DOME sheet, makes it not easily produce movement.

Preferably, the material of described insulating blanket is rubber.
Preferably, described protuberance and described insulating blanket are formed in one and make.Production efficiency can be increased by one-body molded.
Preferably, described insulating blanket connection bonding with described wiring board.
Preferably, described pressing piece comprises one for the press surface with described protrusion contacts, and described press surface is plane.Plane can ensure better and protrusion contacts.
The present invention also comprises a kind of mobile terminal, and its feature is, it comprises described button, and described pressing piece is embedded on the casing of described mobile terminal, and described wiring board is electrically connected with the mainboard of described mobile terminal.Mobile terminal is mostly handheld device, and operating condition is not good, and user also payes attention to more to feel, described by the better raising operating handle of bond energy by using.
In the present invention, above-mentioned optimum condition can combination in any on the basis meeting this area general knowledge, obtains each preferred embodiment of the present invention.
Positive progressive effect of the present invention is: by utilization of the present invention, can improve the pressing feel of button, reduces misoperation, effectively avoids button malfunction.
