In view of this, the utility model is for the disappearance of prior art existence, its main purpose is to provide a kind of high intensity button, by arranging contact portion, annular skew wall and annular vertical wall in lower end, press section, angle between annular skew wall and contact portion is set to 40-45 °, thus, utilize angle to arrange and press-key structure coordinates raising button toughness, strengthen button bulk strength, extend button service life.
For achieving the above object, the technical scheme that the utility model employing is following:
A kind of high intensity button, include press section, it is integrally formed at lower end, press section for contacting the contact portion of circuit board, it is integrally formed at the annular skew wall on dual-side edge, lower end, press section, it is vertically arranged at annular skew wall lower end for strengthening the annular vertical wall of button overall flexibility and being integrally formed at annular vertical wall lower end for supporting press section, contact portion, annular skew wall and the supporting part of annular vertical wall entirety, this contact site is in lower end, press section center position, its cross section is narrower than press section cross section, between this annular skew wall and contact portion outer wall, angle is 40-45 °, in the middle part of this supporting part, above-mentioned contact portion is provided with pressing space, this pressing Space Cross Section is wider than above-mentioned contact portion cross section.
As a kind of preferred version: described button material is silica gel.
As a kind of preferred version: described circular slanting wall thickness is 0.40-0.42mm.
As a kind of preferred version: described annular vertical wall height is 0.34-0.36mm.
As a kind of preferred version: described annular vertical wall and annular skew wall total height are 1.1-1.3mm.
As a kind of preferred version: described supporting part height is 1.1-1.2mm.
As a kind of preferred version: distance pressing space, described contact portion lower end lower surface distance is 1.34-1.36mm.
The utility model compared with prior art has clear advantage and beneficial effect, specifically, as shown from the above technical solution, by arranging contact portion in center, lower end, press section, in lower end, press section dual-side along being wholely set annular skew wall, angle between annular skew wall and contact portion is set to 40-45 °, thus, annular press section transmission pressure suffered by skew wall is made most preferably to be decomposed, reduce and press pressure suffered by annular skew wall, improve and press bond strength, and it is wholely set annular vertical wall in annular skew wall lower end, this annular vertical wall can share annular skew wall pressure, and play the effect supporting button, thus, improve button toughness further, strengthen button bulk strength, simultaneously, pressing more has sense of touch, extend the service life of button.
For more clearly illustrating architectural feature of the present utility model and effect, it is described in detail with specific embodiment below in conjunction with the accompanying drawings.

Detailed description of the invention
The utility model as depicted in figs. 1 and 2, a kind of high intensity button, include press section 10, contact portion 20, annular skew wall 30, annular vertical wall 40 and supporting part 50, wherein:
This press section 10 is touched for finger pressing with switch-on keying circuit；This contact portion 20 is integrally formed at lower end, press section 10 and realizes circuit turn-on with the contact circuit board when the 10 times pressures in press section, and this contact portion 20 is positioned at lower end, press section 10 center position, and its cross section is narrower than press section 10 cross section；This annular skew wall 20 is integrally formed at dual-side edge, lower end, press section 10, between this annular skew wall 30 and contact portion 20 outer wall, angle a is 40-45 °, this design can make button when pressurized, pressure can obtain an equitable breakdown, improving key press toughness, this annular skew wall 30 thickness b is 0.40-0.42mm；This annular vertical wall 40 is integrally formed at annular skew wall 30 lower end; this annular vertical wall 40 height c is 0.34-0.36mm; this annular vertical wall 40 and annular skew wall 30 total height d are 1.1-1.3mm; when pressing keys; annular vertical wall 40 can play support and share annular skew wall 30 pressure; thus improve button toughness further, make button compression number to increase, extend button service life；This supporting part 50 is integrally formed at annular vertical wall 40 lower end, this supporting part 50 height e is 1.1-1.2mm, it is overall that it is used for supporting press section 10, contact portion 20, annular skew wall 30 and annular vertical wall 40, and in the middle part of supporting part 50, above-mentioned contact portion 20 is provided with pressing space 51, this pressing space 51 cross section is wider than above-mentioned contact portion 20 cross section, and contact portion 20 lower end is 1.34-1.36mm with pressing space 51 lower surface distance f；This button generally silica gel material.
Key press rebound stroke curve synoptic diagram is described as follows: when top curve is key press state, key press stroke curve, when lower curve is button resilience, and button rebound stroke curve.When in key press stroke curve, P1 point represents button depressed power F1, button downward stroke reaches S1, the peak force that herein can bear for button annular skew wall and annular vertical wall, is button annular skew wall and peak power that annular vertical wall can bear；After having crossed P1 point, button can bear power and falls down the most suddenly, this is because the annular skew wall of button and annular vertical wall start bending and bear the most original strength, make button dramatic decrease until touching on base plate, now button stress F2 stroke arrives S2, it is in P2 contacting points position, if now continuing button is applied pressure, by pressure rapid increase, but button can press down the most very much (stroke is the shortest) almost to be terminated, strength F5 applied in theory can be infinitely great, but simply at pressing silica gel, is in P5 point.Button rebound stroke curve, when being applied on button after pressure cancellation, button can first discharge the pressure being originally compressed on silica gel, until being returned to P3 point (corresponding S3 stroke by P5 point, button is by F2 pressure and base plate just contact position), after having crossed P3 point, button starts bounce-back, and bounce is increasing, till knowing that annular skew wall and annular vertical wall no longer bend, after arriving P4 point (screen resilience F4), button bounce is linear more and more less, until returning to initial point.
Design focal point of the present utility model is, by arranging contact portion in center, lower end, press section, in lower end, press section dual-side along being wholely set annular skew wall, angle between annular skew wall and contact portion is set to 40-45 °, thus, annular press section transmission pressure suffered by skew wall is made most preferably to be decomposed, reduce and press pressure suffered by annular skew wall, improve and press bond strength, and it is wholely set annular vertical wall in annular skew wall lower end, this annular vertical wall can share annular skew wall pressure, and play the effect supporting button, thus, improve button toughness further, strengthen button bulk strength, simultaneously, pressing more has sense of touch, extend the service life of button.
The above, it it is only preferred embodiment of the present utility model, not technical scope of the present utility model is imposed any restrictions, therefore every according to technical spirit of the present utility model to any trickle amendment made for any of the above embodiments, equivalent variations and modification, all still fall within the range of technical solutions of the utility model.
