<P>PROBLEM TO BE SOLVED: To achieve a separate connector structure having both of noise resistance and a simple structure. <P>SOLUTION: Positive and negative electrode sides piezo lead wires 4 of a piezo actuator A, positive and negative electrode sides piezo terminals 12 of a piezo connector B, first to fourth sensor leads 9 of a fuel pressure sensor S and first to fourth sensor terminals 22 of a sensor connector C are installed at positions separate from each other by a predetermined distance. Thus, the drive signal of the piezo actuator A is hardly superposed on the analog pressure signal as noise, and the noise resistance can be improved as a result. Further, a rotation positioning connector of a complicated shape can be omitted, and thus, the electric connection structure of each sensor electrode 21 of the first to fourth sensor leads 9 to the first to fourth sensor terminals 22 can be simplified. <P>COPYRIGHT: (C)2013,JPO&INPIT |
