Because the button of remote controller is more usually, corresponding button pcb board area is larger, and this will expend a lot of pcb board material material and copper product, and production cost is higher.

The utility model content

The purpose of this utility model is to provide a kind of remote controller with simple key plate, can save the button pcb board, saves material, and production cost is lower.

The purpose of this utility model is achieved through the following technical solutions: a kind of remote controller with simple key plate, comprise housing, be distributed in the button on the housing and be located at the interior master control pcb board of housing, described master control pcb board has for the input interface that receives push button signalling; Described remote controller also comprises the plastic button panel that is positioned at housing, the plastic button panel top layer is provided with conducting wire and a plurality of key contacts through electrically conductive ink printing moulding, wherein, the distributing position of each key contacts of described printing moulding is corresponding one by one with the distributing position of described button, after key contacts produces push button signalling, transfer to the corresponding input interface of master control pcb board through the conducting wire.

On the basis of the above, the utility model can be done following improvement:

Plastic button panel described in the utility model is an independent sheet.

The inner bottom surface layer of housing described in the utility model is beneficial to further saving material as the printing top layer of described plastic button panel, reduces cost.

Remote controller described in the utility model also comprises the zebra bar, and described conducting wire is connected with the input interface line of master board through the zebra bar, is beneficial to the assembling of plastic button panel and master control pcb board.

Compared with prior art, the utility model technology has the following advantages:

The utility model receives push button signalling by conducting wire and the key contacts of printing at plastic button panel, saved traditional button pcb board, simplified the structure of former pcb board, be easy to produce, also greatly save pcb board material material and copper product, reduced production cost.
