Abstract
The utility model relates to a press key of a mobile phone. The press key comprises a layer of polyester film which can be in particular a polycarbonate film; the surface of the polycarbonate film is provided with character keys formed by two times of injection molding while the back thereof is flexibly contacted with a conductive film of the mobile phone. Since the character keys on the press keys on the mobile phone are formed by twice injection molding, the thickness of the press key of the mobile phone is greatly reduced and the press key of the utility model has the advantages of simple technique and low cost. Additionally, the character key formed through twice injection molding has a concave and convex three-dimensional effect and a more beautiful appearance.
Description
Technical field
The utility model relates to a kind of mobile phone key, relates in particular to the mobile phone key of slim mobile phone, belongs to the structure-design technique of mobile phone key.
Background technology
Slim mobile phone is the extremely thin mobile phone type of a kind of integral thickness.The mobile phone of this type height of each parts on the requirement mobile phone when design all reaches and minimizes, to reach the purpose that reduces the mobile phone integral thickness.Wherein, the thickness of mobile phone key is one of the principal element that influences the integral thickness of mobile phone, in order to satisfy the requirement of mobile phone slimming, some ultra-thin keys occurred in the existing technology, mainly contains two classes:.Foil type button and polyester sheet type button.
The foil type button is to adopt foil material, at the sheet metal surface hollow-out and adhere to flexible material to support feel preferably.Defective is: cost of raw material height, and complex process, the production difficulty is big, the price height; And character keys do not protrude, and appearance is single, and metallic elastic is limited in scope, and touch feeling is poor.
Polyester sheet type button is similar to the sheet metal press-key structure, has just replaced foil material by the polyester sheet material.Defective is: the thickness requirement of polyester sheet more than 0.4mm, thereby make whole button thickness surpass 1mm, be unfavorable for further reducing the mobile phone integral thickness; And character keys is not protruded, and touch feeling is poor, and appearance and modeling is simple.
The utility model content
Problem to be solved in the utility model is: the slim mobile phone key that a kind of very thin thickness and manufacturing process are simple, cost is low is provided.
In order to address the above problem, an embodiment of the present utility model has provided a kind of mobile phone key, comprising: one deck polycarbonate membrane has the character keys that forms by quadric injection mould on described polycarbonate membrane surface; The back side of described polycarbonate membrane and mobile phone conducting film Elastic Contact.
By the utility model,, therefore greatly reduce the thickness of mobile phone key because the character keys on the mobile phone key forms by quadric injection mould; And manufacturing process is simple, cost is low; In addition, the character keys of quadric injection mould also has concavo-convex stereoeffect, makes it more attractive in appearance.
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
Description of drawings
Fig. 1 is the Facad structure schematic diagram of the utility model embodiment 1 described mobile phone key;
Fig. 2 is the cross section structure schematic diagram of the utility model embodiment 1 described mobile phone key;
Fig. 3 is the cross section structure schematic diagram of the utility model embodiment 2 described mobile phone keys;
Fig. 4 is the distributing position schematic diagram of the utility model embodiment 2 described conduction bases.
Embodiment
Present embodiment provides a kind of mobile phone key of slim mobile phone, as shown in Figure 1, 2, comprise: one deck mylar, particularly, this mylar can be polycarbonate (Polycarbonate, be called for short: PC) film 1, has the character keys 11 that forms by quadric injection mould on PC film 1 surface, and this character keys comprises numerical key and " * " operating keys such as " # " of 0-9.
Wherein, the thickness of PC film 1 is 0.25mm; The thickness of character keys is 0.15mm.Particularly, character keys can form by the transparent material of quadric injection mould PC.(be called for short: the 3 Elastic Contact DOME film) are transmitted to by the mobile phone conducting film in the control circuit of mobile phone inside, to realize the function of mobile phone key for the back side of PC film 1 and mobile phone conducting film.
Therefore character keys on the described mobile phone key of present embodiment forms by quadric injection mould, greatly reduces the thickness of mobile phone key, and (be called for short: Rubber) the formula button has reduced about 1mm than the PC film+rubber of routine; And manufacturing process is simple, cost is low; In addition, the character keys of quadric injection mould also has concavo-convex stereoeffect, makes it more attractive in appearance.
Present embodiment improves mobile phone key on the basis of embodiment 1, as shown in Figure 3, also further is pasted with flexible film 2 at PC film 1 back side, between PC film 1 and mobile phone conducting film 3.
Wherein, flexible film 2 can be soft silica gel film or soft rubber film, and its thickness can be 0.25mm.And the back side of flexible film 2 also is provided with conduction base 22.The thickness of this conduction base 22 can be 0.3mm.Particularly, the distributing position of conduction base 22 on flexible film 2 can be as shown in Figure 4, and be corresponding with the position of character keys.
By the described mobile phone key of present embodiment, owing to increased flexible film 2 and conduction base 22, the excellent handle when therefore having increased button.And the integral thickness of the described mobile phone key of present embodiment is: 0.25mm (thickness of PC film 1)+0.15mm (thickness of character keys 11)+0.25mm (thickness of flexible film 2)+0.3mm (thickness of conduction base 22)=0.95mm.This thickness still can satisfy the thickness requirement of slim mobile phone.
It should be noted that at last: above embodiment only in order to the explanation the technical solution of the utility model, is not intended to limit; Although the utility model is had been described in detail with reference to previous embodiment, those of ordinary skill in the art is to be understood that: it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, and perhaps part technical characterictic wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the spirit and scope of each embodiment technical scheme of the utility model.
