Pressure sensor and related method
First Claim
1. A pressure sensor comprising:
- a connector case carrying thereon an electrically conductive terminal;
a housing adapted to be supplied with a pressure to be detected and fixedly carrying thereon the connector case;
a capacitor supported by the connector case and connected to the terminal to allow noises, inputted through the terminal, to be outputted to an outside; and
a sensor section mounted to the connector case at one end thereof for detecting the pressure introduced to the housing to deliver a pressure detection signal through the terminal;
wherein the connector case includes a primary resin section, fixedly supporting the capacitor and the terminal, and a second resin section by which a joint area between the terminal and the capacitor and the primary resin section are enfolded and sealed.

Abstract
A pressure sensor and related manufacturing method are disclosed wherein a connector case 10 is coupled to a housing 30 in a unitary structure. The connector case 10 includes a primary resin section 101 that enfolds and seals a terminal 12 while fixedly supporting a capacitor 16 on the terminal 12. The primary resin section 101 is encompassed by a secondary resin section 102 so as to enfold and seal the primary resin section 101 such that both ends of the terminal 12 are exposed to an outside. In one aspect, the primary resin section 101 enfolds and seals the capacitor and the terminal. In another aspect, the primary resin section 101 enfolds and seals the terminal and is formed with fixing portions 101a, 10ab, 101c by which the capacitor is fixedly supported on the terminal.
