ABSTRACT:
An acceleration detector including an acceleration transducer assembly including a piezoelectric element, an output terminal and an inertial weight. The transducer assembly is secured on a threaded bushing by a substantially ring-shaped, thread-engaging stop nut thread-engaging to the threaded bushing. The stop nut has an internal thread in its inner circumferential surface and a pair of axially extending engagement grooves formed in its outer circumferential surface at equal intervals for receiving a tool for rotating the stop nut about the bushing. The output terminal may have a ring-shaped portion, a connecting tab radially outwardly extending from the ring-shaped portion for an external connection, and a transition fillet provided at a transition area between the ring-shaped portion and the tab for moderating the concentration of stress on the transition area.
