Abstract

The utility model relates to a drawing-out type film press key, comprising a press key body and a press key sheet. A layer of ink which is not transparent but can be stretched is printed on the lower surface of the press key sheet, and desired characters or patterns are carved on the ink on the lower surface of the press key sheet. Desired colors are printed on the positions of the characters or the patterns. The color ink is transparent ink. A press key shape whose lower surface is in a concave shape is drawn out from the press key sheet, and a layer of hard transparent press key body which is corresponding to the shape of the bottom surface of the press key sheet is formed on a concave position in an injection forming technology. The press key body is soft silica gel material. The hard transparent press key body is embedded on the press key body. A conductive element is arranged on the lower surface of a soft body.

Description

Take out the type film key

The utility model relates to a kind of type film key of taking out, and makes the button after the improvement can avoid producing the finger pressure indenture on the button piece surface when pushing.

Be used in electronic product such as mobile phone, remote controller, tiny computer traditionally ... Deng membrane pushbutton, its structure includes: a keying body and a button piece, the end face of this keying body are printed on the pigment of light-permeable; This button piece then is simultaneously to be printed with the opaque and stretchable printing ink of one deck at a clear films sheet, and this button piece taken out the fit portion that type goes out to have corresponding keying body, make this printing ink be positioned at button piece below, and on the printing ink of fit portion bottom surface, carve out required literal or figure, this literal or figure are not covered and light-permeable by printing ink; The fit portion of this button piece is sheathed on the keying body to be combined as a whole, uses making keying body have resistance to wear, grease resistance permeability and light transmission.

But, because the button piece of aforementioned conventional is the hard shell of thickness about 0.1～0.125mm, and keying body is softer silica gel material, produce the signature trace so might apply strength because of harder nail when pointing in pressing keys in the button piece surface, and should give as security the difficult recovery of trace.Therefore, the utility model is improved at the existing defective of this conventional thin membrane type button.

Main purpose of the present utility model provides a kind of type film key of taking out, and can avoid when mainly being pressing keys producing the signature trace on the button piece surface.

Based on this, the type film key of taking out provided by the utility model, it includes a keying body and a button piece, be printed with one deck not light-permeable and stretchable printing ink below this button piece, and carve out required literal or figure on the printing ink below button piece, again in literal or figure place printing required color, and this color ink is the printing ink of light-permeable, this button piece is taken out the key shape that type is concavity below going out, sentence ejection forming technique in this concavity again and form the hard transparent key body of one deck corresponding to this button piece bottom shape, this keying body is soft silica gel material, this hard transparent key body is embedded in keying body, is provided with a conducting element below this soft body.This hard transparent key body is to adopt the hard resin material to make.

The utility model is described in further detail for following conjunction with figs.:

Fig. 1 is that demonstration the utility model is taken out the section plan of type film key structure.

Among the figure,

1 button piece, 4 hard transparent key bodies

2 light-permeable printing ink 5 keying body not

3 light-permeable printing ink, 6 conducting elements

As shown in Figure 1, the type film key of taking out provided by the utility model include a keying body 5 and a button piece 1, and this keying body 5 is combined in below the button piece.Wherein, this button piece 1 is to make with the plastic material of hard; This keying body 5 is soft bodies made from the silica gel material, be provided with a conducting element 6 in the lower end of this keying body 5, this conducting element 6 can be the metal clips with conductivity, and 5 of the keying body of top that should conducting element 6 are had the part that projects upwards.

Be printed with the stretchable not light-permeable of one deck printing ink 2 below this button piece 1, this printing ink can be not dark color of light-permeable of black or other, and carve out required literal or figure on the not light-permeable printing ink 2 below button piece 1, again in literal or figure place printing required color, and this color ink is a light-permeable printing ink 3, after this button piece 1 is taken out the key shape that type is concavity below going out, sentence ejection forming technique in this concavity again and form the hard transparent key body 4 of one deck corresponding to this button piece bottom shape; This hard transparent key body 4 is embedded in keying body 5, constitutes a film key according to this.

After aforementioned film key of the present utility model is assembled in circuit board, when pressing keys sheet 1, equal pressing keys body 5 simultaneously, and when keying body 5 is mobile downwards, conducting element 6 below it promptly can touch contact position (not shown) set on the circuit board and conduct electricity, and by the strengthening action of hard transparent key body 4 set below button piece 1, can increase the intensity of button piece 1 and avoid finger or nail when forcing in button piece 1 surface, form the signature trace on button piece 1 surface, this kind design has had the essence effect that more traditional film key is promoted effect.

The above in order to explain preferred embodiment of the present utility model, is not that attempt is right according to this only

The utility model is done any pro forma restriction, all have in that identical invention spirit is following do relevant any modification of the present utility model or change, all must be included in the scope of the utility model protection.

Claims

1. take out the type film key for one kind, include a keying body and a button piece, this button piece is to make with hard plastics, and this keying body is to make with soft silica gel material, and be provided with a conducting element in the bottom surface of keying body, be printed with one deck not light-permeable and stretchable printing ink below this button piece, and carve out required literal or figure on the printing ink below button piece, in literal or figure place printing required color, and this color ink is the printing ink of light-permeable, this button piece is taken out the key shape that type is concavity below going out, it is characterized in that:

The concavity of described button piece below is sentenced ejection forming technique and is formed the hard transparent key body of one deck corresponding to this button piece bottom shape, and this hard transparent key body is embedded in described keying body.
