Mounting clips for thickness shear piezoelectric oscillator

Claim 1

A thickness shear piezoelectric oscillator comprising: (a) an insulating base plate; (b) a lead terminal extending through said insulating base plate and secured thereto; (c) a supporting means provided at that portion of said lead terminal which is extended through and projected from said insulating base plate; (d) an oscillation piece provided at its both ends with bevel portions and having a node point of bending oscillation of the upper and lower surfaces of said bevel portions, said node point being supported by said supporting means; (e) an electrode provided at the center part of said oscillating piece; (f) a lead portion formed on said oscillating piece and for electrically connecting said electrode to said lead terminal; (g) a cap secured to said insulating base plate and hermetically covering said oscillating piece; (h) the end surface of said bevel portion of said oscillating piece is supported by a horizontal position determining means for the purpose of determining the position of said oscillating piece in its horizontal direction; (i) said horizontal position determining means is provided in a direction perpendicular to the direction of providing said supporting means; (j) said horizontal position determining means is comprised of a thin plate having two legs terminating in opposed projections, said projections engaging the sides of the oscillating piece; and (k) the supporting means includes opposing supporting members for engaging the upper and lower surfaces of said bevel portions for vertically supporting the oscillating piece.
