受波器。 An annular piezoelectric ceramic vibrator with electrodes formed on both end faces in the thickness direction, polarized in the thickness direction, and vibrates.
A bolt-tight lunge type vibrator for an underwater ultrasonic transducer is constructed by sandwiching metal blocks from both sides through an electrode plate and an insulating plate and tightening bolts. ,
Hollow out the inside of the bolt that tightens the metal block to create a hollow part, insert the terminal part of the signal transmission cable into the hollow part, and connect the terminal of the signal line to the vibrator electrode via the internal hollow part of the annular electrode. The cable is fixed to one end of the bolt, and the piezoelectric vibrator,
An underwater ultrasonic transducer characterized in that a metal block, a tightening bolt and nut, and the tip of a signal transmission cable are integrally molded to form a watertight structure.
