| 摘要 |
The present invention relates to a pressure sensor comprising: a metal diaphragm provided with a pressure sensing unit on an upper portion thereof; a first support combined with the metal diaphragm; a first printed circuit board supported by the first support, arranged on the pressure sensing unit, and electrically connected to the pressure sensing unit; a connector to which a lower portion of the first printed circuit board is press-fitted; a second printed circuit board electrically connected to the first printed circuit board via the connector when the upper portion of the connector is press-fitted onto the second printed circuit board, and which is supported by the connector to be arranged above the first printed circuit board but with a gap separating them; a second support arranged on the second printed circuit board; and a spring electrode which passes through the second support such that an upper end thereof protrudes from an upper surface of the second support, and a lower end thereof is connected to the second printed circuit board. According to the present invention, an electrical connection between printed circuit boards is made in a pressure-fitted manner using a connector such that soldering is unnecessary. |
