Patent ID: 7504943

Claim:
An object detecting apparatus, comprising: a piezoelectric sensor including a first electrode having an end portion, a piezoelectric material surrounding the first electrode, and a second electrode having an end portion and surrounding the piezoelectric material, the piezoelectric sensor being adapted for being provided at an outer edge portion at a side of an opening of a door for a vehicle having a door panel; a signal processing circuit measuring a potential difference between the first electrode and the second electrode; a connecting line for connecting the first electrode and the second electrode to the signal processing circuit, the connecting line being in the form of a shield wire and including a first conductor having an end portion, an insulating body surrounding the first conductor, and a second conductor surrounding the insulating body and having an end portion; a case; a bush fixedly mounted at one end of the case and having holes through which the piezoelectric sensor and the connecting line extend, in a spaced parallel mode, into the case; a first conductive connecting member provided in the casing and electrically connected between the end portion of the first electrode of the piezoelectric sensor and the end portion of the first conductor of the connecting line; and a second conductive connecting member provided in the casing and electrically connected between the end portion of the second electrode of the piezoelectric sensor and the end portion of the second conductor of the connecting line.
