Abstract
The utility model relates to a capacitive-sensor pole plate, and the pole plate comprises a printed circuit board which is provided with a pole plate unit. The pole plate unit is a copper layer attaching to the printed circuit board, or a metal plate which is disposed on the printed circuit board. Compared with the prior art, the pole plate provided by the utility model reduces the size of the printed circuit board, saves cost, and is more convenient for assembly.
Description
Technical field
The utility model relates to a kind of capacitive transducer correlation technique, especially relates to a kind of capacitive transducer pole plate.
Background technology
Along with the development of electronic technology, capacitance detecting chip has more and more been applied in our life.In our application, the design of capacitive transducer is also more and more important.
The domestic mode generally adopting is on printed circuit board (PCB), covers a copper and makes capacitor plate.The area of the printed circuit board (PCB) that such design causes is very large, and cost is higher, causes the volume that occupies larger simultaneously, needs the volume of sealing also larger.
Utility model content
The purpose of this utility model is exactly to provide a kind of capacitive transducer pole plate in order to overcome the defect that above-mentioned prior art exists.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of capacitive transducer pole plate, is characterized in that, comprise printed circuit board (PCB), this printed circuit board (PCB) is provided with pole plate, and this pole plate is be attached to the copper layer on printed circuit board (PCB) or be assemblied in the sheet metal on printed circuit board (PCB).
Described sheet metal is welded on printed circuit board (PCB).
Described sheet metal is connected with printed circuit board (PCB) by fixed block.
Described sheet metal and fixed block are vertical setting, and described fixed block and printed circuit board (PCB) are vertical setting.
Described sheet metal is connected with printed circuit board (PCB) by contact pin.
Compared with prior art, the utility model, by utilizing the copper layer on printed circuit board (PCB), replaces the mode of capacitive transducer pole plate simultaneously by sheet metal, reduce the area of printed circuit board (PCB), cost-saving, assembles convenient.
