Description
Technical field
The utility model relates to a kind of electric equipment, particularly relates to a kind of remote controller.
Background technology
On mobile phone, be widely used at present LED light source and light guide plate and provide the technology of illumination for button, and also never use in remote controller, on mobile phone, be mainly to provide large area leaded light for mobile phone key, can not effectively in particular surroundings, use, its major defect is the accurate positioning luminous that can not accomplish button position.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of remote controller that can make the accurate printing opacity in button position.
The utility model remote controller, comprise pcb board, DOME sheet and the keypad arranged successively from down to up, described pcb board is provided with LED light source, between the lower surface of the upper surface of described pcb board and DOME sheet, be provided with a light guide plate, the upper surface of described DOME sheet is provided with one deck conducting resinl, the upper surface of described conducting resinl is provided with a light shield layer, and light shield layer is provided with loophole, and described keypad is positioned at the top of light shield layer and is adjacent to mutually with light shield layer.
The utility model remote controller, the light shield layer that wherein said conducting resinl upper surface is provided with is a light-shielding sheet, described loophole is opened on light-shielding sheet.
The utility model remote controller, the light shield layer that wherein said conducting resinl upper surface is provided with is one deck blacking being sprayed on conducting resinl, described loophole is opened on blacking and is penetrated conducting resinl.
The utility model remote controller, the aperture of wherein said loophole is 0.5～2.5mm.
The utility model remote controller difference from prior art is to be provided with a light guide plate between the pcb board of the utility model remote controller and DOME sheet, under the irradiation of the LED light source on pcb board, light guide plate self can be sent uniform light, and be provided with one deck conducting resinl at the upper surface of DOME sheet, and the upper surface of conducting resinl is provided with a light shield layer, according to the position of button on keypad and in the punching of the relevant position of light shield layer, the light that light guide plate sends is like this after light shield layer effect, only can appear light in the button position on keypad, so just accomplished the accurate printing opacity at button position.
In the utility model remote controller, the aperture of loophole is 0.5～2.5mm, and light shield layer can play and block the unnecessary effect backlight of button like this, can reach again the requirement of the accurate printing opacity in button position.
Below in conjunction with accompanying drawing, the utility model is described in further detail.

Embodiment
As shown in Figure 1, and in conjunction with shown in Fig. 2,3,4,5,6, the utility model remote controller comprises pcb board (not shown), DOME sheet 1 and the keypad (not shown) of arranging successively from down to up, described pcb board is provided with LED light source, between the lower surface of the upper surface of described pcb board and DOME sheet 1, be provided with a light guide plate 2, the upper surface of described DOME sheet 1 is provided with one deck conducting resinl 3, the upper surface of described conducting resinl 3 is provided with a light shield layer, light shield layer is provided with loophole 5, and described keypad is positioned at the top of light shield layer and is adjacent to mutually with light shield layer.The light shield layer that described conducting resinl 3 upper surfaces are provided with can be both a light-shielding sheet 4 that is provided with loophole 5, also can be without light-shielding sheet 4, but directly by upper surface spray one deck blacking of conducting resinl 3, by Radium art, on the black conducting resinl 3 of spray, get loophole 5 more afterwards.The aperture of described loophole 5 is 0.5～2.5mm.
The Chinese of described pcb board is printed circuit board, claim again printed circuit board (PCB), printed substrate, be called for short printed board, often use english abbreviation PCB(Printedcircuitboard) or write PWB(Printedwireboard), take insulation board as base material, be cut into certain size, on it, at least has a conductive pattern, and cloth porose (as component hole, fastener hole, plated-through hole etc.), be used for replacing the chassis in the past installed electronic devices and components, and realize interconnecting between electronic devices and components.Because this plate is to adopt electron printing to make, therefore be called as " printing " circuit board.
Described DOME sheet 1 is a PET thin slice that comprises metal clips (the young sheet of pot), is used on the wiring boards such as PCB or FPC and uses as switch, plays the effect of an important sense of touch type switch between user and instrument.Compare with traditional silica gel push-button, film key has better feel, longer life-span, also can indirectly improve the production efficiency of all types of switches that use conducting film.
Above-described embodiment is described preferred implementation of the present utility model; not scope of the present utility model is limited; do not departing under the prerequisite of the utility model design spirit; various distortion and improvement that those of ordinary skills make the technical solution of the utility model, all should fall in the definite protection range of the utility model claims.
