Claims

[Claims for Utility Model Registration] A pair of first and second lead wires that pass through both ends of a metal outer ring and are insulated and sealed with glass, and A third lead wire passes through the bottom of the formed recess and is sealed with a brazing material, and a third lead wire extends upward from the tips of the first and second lead wires and connects electrically to both ends of the crystal vibrating piece. A first support and a second support of elastic conductive material that are mechanically connected.
and a third support made of an elastic conductive material that extends upward from the tip of the third lead wire and is electrically connected to the lower peripheral edge of the crystal vibrating piece, the third support being The support extends upward from the tip of the third lead wire located near the bottom of the recess of the metal outer ring, and is connected between the third lead wire and the tip connected to the crystal vibrating piece. An airtight terminal for a crystal resonator, characterized by having a bent portion that absorbs vibrations applied to the crystal resonator.
