Abstract
A universal crystal holder is provided which is capable of supporting piezoelectric crystals having virtually any size and shape. The crystal holder includes two support structures, each having a downwardly sloping surface for accepting a side of the crystal to be supported. Since crystals placed in the universal crystal holder of the invention are self-aligned, the placement of a crystal in the holder is easily automated.
Claims5
A crystal holder for supporting a piezoelectric crystal having upper and lower surfaces including:
- a first element of electrically conductive material having a downwardly sloping first surface for contacting and supporting the lower surface of said crystal at an end thereof;
- a second element of electrically conductive material having a downwardly sloping second surface for contacting and supporting the lower surface of said crystal at another end thereof, said second surface facing said first surface in a V-like manner;
- and
- each of said first and second elements being electrically insulated from the other and including a mounting portion facing the other of said first and second elements, said mounting portion being sufficiently massive to prevent said first and second elements from tipping over when mounted on a substrate.
