The present invention relates to a sensor for a vehicle to block an introduction of potting liquid into a gap, which is caused by a dimensional tolerance, between a housing and a rubber cap when the potting liquid for air-tightening the inside of a sensor is injected into the inside of the housing, such that a ring time signal of a sensor cell is prevented from being elongated. The sensor includes: a housing formed in a hollow shape, having one end formed with an accommodation groove communicating with the outside and an opposite end formed with a coupling groove; a rubber cap disposed at the coupling groove and formed therein with a seating groove; a sensor cell inserted into the seating groove; a PCB disposed at the accommodation groove and connected to the sensor cell; and potting liquid filled in the accommodation groove for air-tightening one end of the rubber cap and the PCB from the outside. A blocking part protrudes from the end of the rubber cap, and the blocking part makes contact with the inner surface of the housing, so that the potting liquid is prevented from being introduced into between the housing and the rubber cap.

    본 발명은 감지센서의 내부를 기밀시키는 포팅액을 하우징의 내부로 주입할 때, 포팅액이 치수공차로 인해 생기는 하우징과 러버캡 사이의 틈 사이로 유입되는 것을 저지하여 센서셀의 링타임 신호가 늘어나는 것을 방지하는 것으로서, 일단에 외부와 연통되는 수용홈이 형성되고, 타단에 결합홈이 형성된 중공형상의 하우징, 상기 결합홈에 배치되고, 내부에 안착홈이 형성되는 러버캡, 상기 안착홈에 삽입 배치되는 센서셀, 상기 수용홈에 배치되어 상기 센서셀과 연결되는 PCB, 상기 수용홈에 충진되어 상기 러버캡의 일단 및 상기 PCB를 외부로부터 기밀시키는 포팅액을 포함하되, 상기 러버캡의 일단 방향에 차단부가 돌출 형성되고, 상기 차단부는, 상기 하우징의 내측면과 접하여 상기 하우징과 상기 러버캡 사이에 상기 포팅액이 유입되는 것을 방지한다.
