Abstract
In an ultrasonic sensor, a lead pin electrically connecting a piezoelectric element to a printed circuit board (PCB) assembly is inserted into a fixed block, and the fixed block is fused to a housing, thereby minimizing an assembly error and thus improving performance and reliability.
Claims20
An ultrasonic sensor comprising:
- a housing open in a front and a rear thereof to form an accommodation space in the housing;
- a cell case inserted into the front of the accommodation space and open in a rear of the cell case to form an inner space therein;
- a piezoelectric element disposed in a front of the inner space;
- a printed circuit board (PCB) assembly inserted into the accommodation space and disposed in the rear of the cell case;
- a lead-pin assembly electrically connecting the piezoelectric element to the PCB assembly in the accommodation space;
- a filler filled in a space requiring electrical connection between the piezoelectric element and the PCB assembly in the accommodation space and the inner space;
- and
- a rear cover sealing a rear of the accommodation space,
- wherein the lead-pin assembly comprises:
- a lead pin having a first end electrically connected to the PCB assembly and a second end electrically connected to the piezoelectric element;
- and
- a fixed block into which the lead pin is inserted and which is fused to the housing.

- a printed circuit board (PCB) assembly inserted into the accommodation space and disposed in the rear of the cell case;
- a lead-pin assembly electrically connecting the piezoelectric element to the PCB assembly in the accommodation space;
- a filler filled in a space requiring electrical connection between the piezoelectric element and the PCB assembly in the accommodation space and the inner space;
- and
- a rear cover sealing a rear of the accommodation space,
- wherein the lead-pin assembly comprises:
- a lead pin having a first end electrically connected to the PCB assembly and a second end electrically connected to the piezoelectric element;
- and
- a fixed block into which the lead pin is inserted and which is fused to the housing.
