Abstract
The utility model relates to the field of a portable intelligent terminal technology, and specially relates to a button structure with a light guide plate and a conductive substrate integrated. The button structure with a light guide plate and conductive substrates integrated includes buttons, conductive substrates corresponding to the buttons, the light guide plate, a gummed paper layer, a polyester type high-molecular layer, a partition layer, a metal spring and a protection film which are arranged from up to down. The conductive substrates are integrated with the light guide plate as a whole. By employing the button structure with the light guide plate and conductive substrates integrated, the ultrathin design of handset buttons is realized; products of this kind possess a thin structure and a small occupation space, and are suitable for ultrathin type handsets; and the button touch feeling is good.
Description
Technical field
The utility model relates to portable intelligent terminal technology field, particularly relates to a kind of LGP and the basic incorporate press-key structure of conduction.
Background technology
In recent years, Chinese national economy and new and high technology stable, continue, fast-developing, and the raising of people's living standard impels developing rapidly of China portable intelligent terminal.
Usually, " portable intelligent terminal " is meant that the user can carry the electronic installation that carries out radio communication simultaneously with another user.Such portable intelligent terminal comprises cell-phone, CT-2 cell phone, digital telephone, personal communication service phone (PCS), PDA(Personal Digital Assistant) etc.
And along with the continuous development of mobile phone industry, continuous advancement in technology, people have had very high requirement to the outward appearance and the function of mobile phone, the especially extra-thin mobile phone fashion, popular more that seems.
And existing mobile phone is generally the mechanical type keyboard, and this keyboard makes the key circuit contact realize the conducting or the disconnection of circuit through the distortion of metal clips.
At present, the mechanical type keyboard of mobile phone comprises common key-press and panel button, and it generally includes mobile phone key, conduction base, LGP, metal clips and the PCB wiring board that is provided with from top to bottom; Its operating principle is that finger is pressed the conduction base on the button, and the conduction base makes the distortion of metal clips switch, causes the electronic circuit conducting of PCB wiring board; Realize the associative operation of mobile phone, still, existing conduction base and LGP are arranged for dividing; The keyboard of making like this is thicker, and the touching feel is relatively poor.
Summary of the invention
The purpose of the utility model is to avoid weak point of the prior art, and a kind of LGP and the basic incorporate press-key structure of conduction that is applied to mobile phone is provided, and has really realized the ultrathin design of mobile phone key.
The purpose of the utility model realizes through following technical measures:
A kind of LGP and the basic incorporate press-key structure of conduction; Comprise conduction base, LGP, gummed paper layer, polyesters polymer layer, spacer layer, metal clips and diaphragm that the button that is provided with, corresponding button are provided with from top to bottom, the conduction base is structure as a whole with LGP.
Further, the corresponding conduction of spacer layer base is provided with the shell fragment hole, and correspondence is provided with metal clips in this shell fragment hole.
Further, LGP is a high light transmittance polycarbonate LGP.
Further, diaphragm is the PET diaphragm.
Further, metal clips is a bowl structure.
Further, spacer layer is an adhesive-layer.
Further, LGP is provided with salient point.
The beneficial effect of the utility model:
1, a kind of LGP of the utility model and the basic incorporate press-key structure that conducts electricity; Comprise conduction base, LGP, gummed paper layer, polyesters polymer layer, spacer layer, metal clips and diaphragm that the button that is provided with, corresponding button are provided with from top to bottom; The conduction base is structure as a whole with LGP; Adopt the incorporate press-key structure of this kind conduction base and LGP; Really realized the ultrathin design of mobile phone key, this type product structure approach, occupy the space little, be fit to ultrathin mobile phone and the button feel better.
2, LGP is a high light transmittance polycarbonate LGP, and the utility model button printing opacity is even, and the brilliant degree that the light that LED sends is derived through LGP is high.
3, conduction base and LGP lump together, and reduce the use of material, have reduced production cost.
Description of drawings
Utilize accompanying drawing that the utility model is further specified, but the content in the accompanying drawing does not constitute any restriction to the utility model.

Embodiment
In conjunction with following examples the utility model is described further.
Like Fig. 1; Shown in Figure 2; Described a kind of LGP of the utility model and the basic incorporate press-key structure of conduction; Comprise conduction base 1, LGP 2, gummed paper layer 3, polyesters polymer layer 4, spacer layer 5, metal clips 7 and diaphragm 8 that the button that is provided with, corresponding button are provided with from top to bottom, conduction base 1 is structure as a whole with LGP 2.
Adopt the incorporate press-key structure of this kind conduction base and LGP, really realized the ultrathin design of mobile phone key, this product structure approach, occupy the space little, be fit to ultrathin mobile phone and the button feel better.
LGP 2 is a high light transmittance polycarbonate LGP 2; The preferred light transmittance that adopts reaches the high light transmittance polycarbonate LGP 2 more than 93%; The brilliant degree that the light that LED sends is derived through LGP 2 is high, therefore a spot of LED lamp only need be installed, and just can produce good illuminating effect; Energy savings reduces production costs.
LGP 2 is provided with salient point, can the light that light source sends be reflected, guarantee keyboard luminous everywhere evenly and briliancy higher.
The described a kind of LGP of the utility model with the production process of the basic incorporate press-key structure of conduction is:
At first the process film hot-pressing is with extruding salient point on the LGP 2.
Through UV seal glue process, on LGP 2, print conduction base 1 again with UV glue.
To conduct electricity through the UV line then and basic 1 be solidificated on the LGP 2.
Next carry out die-cut operation, punch out needed shape.
Assemble at last, will conduct electricity base 1 and LGP 2 incorporate structures and gummed paper layer 3, MYLAR (polyester polymer) layer, spacer layer 5, metal clips 7, diaphragm 8 fits together.
Should be noted that at last; Above embodiment only is used to technical scheme of the present invention is described but not to the restriction of protection range of the present invention; Although the present invention has been done detailed description with reference to preferred embodiment; Those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement technical scheme of the present invention, and do not break away from the essence and the scope of technical scheme of the present invention.
