ABSTRACT:
A mounting structure for use with an electronic timepiece comprises a quartz crystal unit disposed within an opening formed in a circuit board and arranged so that the major lengthwise axis of the crystal unit lies parallel with the major plane of the circuit board. A connector formed of heat-deformable material connects the crystal unit to the circuit board and has a cup-shaped portion at one end which is clamped over and supports an end portion of the crystal unit, and a mounting stud at the other end which is inserted through a hole in the circuit board and secured thereto by heat-deforming the end tip of the stud which projects beyond the circuit board to form an enlarged head.
