Abstract
A crystal oscillating device comprises an outer case having a longitudinal axis, a cavity, a pair of first surfaces extending along the longitudinal axis, a pair of second surfaces extending in a direction generally transverse to the longitudinal axis, a first opening portion in one of the first surfaces for providing access into the cavity, a second opening portion in one of the second surfaces, and a groove in the other of the second surfaces. A crystal oscillator is disposed in the cavity of the outer case and has lead terminals extending through the second opening portion of the outer case for electrically connecting the crystal oscillator to a circuit board. A bonding material is disposed in the cavity of the outer case for bonding the crystal oscillator to the outer case. A connecting member is disposed in the groove of the outer case for connecting the outer case to the circuit board.
