Abstract
An ultrasonic sensor includes an ultrasonic transducer and a case. The ultrasonic transducer has a housing in a cylindrical shape with a bottom attached thereto, a piezoelectric device disposed in the housing, a connection pin electrically coupled with the piezoelectric device and a base made of an insulation material for supporting the connection pin extendingly piercing therethrough. The case has an opening for assembly operation of the ultrasonic transducer disposed therein. The piezoelectric device is electrically coupled with a circuit board in the case by using the connection pin and the connection pin is partially protected by a protector portion of the ultrasonic transducer. The case has a guide portion between the ultrasonic transducer and the circuit board for positioning the protector portion in the case.
