A parking sensor device has a casing, a front cover, a sensor module and an assembling clamp. The casing has two first hooking elements. The front cover is mounted on the casing. The sensor module is mounted in the casing and the front cover. The assembling clamp detachably engages the casing and has two second hooking elements. The second hooking elements selectively hook the first hooking elements of the casing respectively. The casing and the assembling clamp are engaged quickly with each other, thereby facilitating the easy fabrication of the parking sensor device and improving the convenience of maintenance of the parking sensor device.

Parking sensor device

An ultrasonic sensor device includes a housing, a transducer, a securing unit and a circuit board. The housing has an enclosing portion formed with first and second openings. The transducer is mounted to the enclosing portion at the second opening, and includes an electrically conductive surrounding wall and a piezoelectric member. The securing unit includes a securing component that secures the transducer on the enclosing portion, and a connecting pin set including two pins each having an end connected electrically to a respective one of the surrounding wall and the piezoelectric member. The circuit board is disposed at the first opening of the enclosing portion for electrical connection with the connecting pin set.

Ultrasonic sensor device

An ultrasonic sensor device includes a housing, a circuit board disposed at the housing, and a transducer. The transducer includes an electrically conductive casing having a bottom wall and a surrounding wall. A piezoelectric member is disposed on top of the bottom wall. A first connecting pin set is disposed in the housing, and includes a first connecting pin having one end connected to the circuit board and another end connected to the piezoelectric member, and a second connecting pin having one end connected to the circuit board and another end connected to the surrounding wall. A second connecting pin set is disposed in the housing, has one end connected to the circuit board, and another end extended into a connecting portion of the housing.
