Description

A kind of mobile phone key

Technical field

The utility model relates to button technical field, particularly relates to a kind of mobile phone key.

Background technology

Mobile phone has become a kind of instrument indispensable in people's life now, and the requirement of people to mobile phone is more and more higher.

, there is following problem in existing mobile phone: character printing opacity on (1) button, and printing opacity is also followed in other regions; (2) keytop is not wear-resistant; (3) with after a period of time, the character on button can become unintelligible; (4) handfeel of keys is poor; (5) insufficient sensitivity of button.

Such as: the patent No. be 99201774.2 Chinese patent disclose a kind of Nonopaque type key; its mobile phone key is transparent silica gel; spray or coat different color layer in keytop zones of different; color layer has the lighttight ink layer of last layer; surperficial at character keys is the radium-shine colourful transparent character window cutting out ink layer; at the protective layer that character keys has an anti-font to disappear on the surface, namely its structure comprises the bottom-up transparent silica gel, color layers, ink layer, character window and the diaphragm that stack gradually.The mobile phone key of this utility model is under the lighting of bottom, and button demonstrates the font of different colours clearly, and font can not disappear because of friction.

Technology disclosed in above patent, although it has added protective layer on character surface, protective layer is very thin after all, and after using a period of time, protective layer is worn, and does not just have the effect of protection to character, and in addition, after increasing protective layer, the feel of button will be deteriorated.

How developing a kind of mobile phone key simultaneously can taking into account following four conditions has then become mobile phone development business to need the problem considered: 1, on button, character is printing opacity, and other regions are light tight; 2, keytop is super wear-resistant, the character that namely conventional friction (paper tape, stainless steel bobbles, denim etc.) can not destroy on button for several ten thousand times; 3, there is the elastic handfeel of silica gel on surface; 4, conductive base is highly sensitive.

Embodiment

With the following Examples the utility model is further described.

A kind of mobile phone key of the present embodiment, as depicted in figs. 1 and 2, comprise PC plastic rubber material conductive base, the first adhesion agent layer, low temperature silicon glue-line, the second adhesion agent layer, ink layer, character layer and TPU film layer, described character layer and ink layer are positioned at same formation legend ink layer of TPU film layer, described first solid connects a face of described legend ink layer and low temperature silicon glue-line, described second solid connects another face and the PC plastic cement bed of material conductive base of described low temperature silicon glue-line, and described ink layer is provided with multilayer.Low temperature silica gel refers to the silica gel that temperature is shaping between 90 to 120 DEG C, because plastic material (TPU film or PC plastic rubber material) softening point temperature is at 120 DEG C, the forming temperature of common silica gel is 150 ~ 250 DEG C, plastic cement can be scorched with ordinary silicon gum forming, low temperature silica gel is used to scorch plastic material, best 110 DEG C of shaping low temperature silica gel effects.

Concrete, described ink layer specifically comprises 7 layers, described 7 layers comprise 4 black ink layer stacked gradually, 2 white ink layers and 1 gloss varnish layer, and described 4 black ink layer connect described TPU film layer, and described 1 gloss varnish layer connects described low temperature silicon glue-line.Because film and print superincumbent ink and can be stretched when oil pressure is shaping, if ink print is thick not, just there will be leakage problem, the ink printed like this would not printing opacity.Find through experiment, arrange 4 black ink layer and can guarantee light tight, 1 gloss varnish layer can improve the adhesive ability with the first solid, and black ink layer and the first solid can separate by white ink layer, avoid affecting black ink layer and causing printing opacity.

Concrete, the thickness of described TPU film is 0.1mm.TPU is TPUE, on Vehicles Collected from Market conventional TPU film thickness be " 0.05,0. 1,0.15,0.2mm " etc. common-use size size.TPU film is too thin and too thickly all can have problems when oil pressure is shaping, and through contrast test, 0.1mm thickness effect is best.0.1mm thickness is purchase standard, and thin and thick JND does not affect use.

The thickness of described first solid is: 3 ~ 5 μm.First solid of this thickness can just realize good cementability, does not waste material again.

Described first solid comprises two-layer, and adhesive effect is better.

A kind of mobile phone key of the present embodiment, has the following advantages: 1, by ink layer is set to multilayer, and character on button can be made to be printing opacity, and other regions are light tight; 2, owing to selecting TPU film as keytop, make keytop super wear-resistant, owing to character to be located at the bottom surface of TPU film, therefore, character can not fall paint; 3, owing to adopting TPU film and the cementing conjunction of low temperature silicon, make keytop just like the elastic handfeel of pressing silica gel; 4, owing to using PC plastic rubber material conductive base, the highly sensitive of conductive base is made.

Finally should be noted that; above embodiment is only in order to illustrate the technical solution of the utility model; but not the restriction to the utility model protection range; although done to explain to the utility model with reference to preferred embodiment; those of ordinary skill in the art is to be understood that; can modify to the technical solution of the utility model or equivalent replacement, and not depart from essence and the scope of technical solutions of the utility model.
