Abstract
Abstract A quartz crystal oscillator element including a substrate of quartz crystal having a plurality of oscillatable parallel prongs extending in a longitudinal direction of the substrate. Parallel metallic electrodes are disposed on each of the prongs thereof. The oscillator element is adhered to a supporting pedestal at a portion of the substrate thereof remote from the prongs. In the embodiment of the invention the electrodes comprise beam leads extending from an end of the substrate for receiving electrical connections to the electrodes. The beam leads are electrically connected to lead pins of additional pedestals so that the substrate bear pressure which develops during electrical connections to the beam leads.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
246 words
The combination comprising: an oscillator element comprising an elongated substrate having a pair of opposed major surfaces and a plurality of oscillatable parallel prongs extending in a longitudinal direction therefrom, and a plurality of metallic electrodes on at least one of said major surfaces, at least one of said metallic electrodes including a unitary beam lead portion extending away from an beyond said substrate in a longitudinal direction therefrom generally parallel to said at least one major surface on which said at least one metallic electrode is disposed and away from said plurality of prongs, said beam lead portions having a remote end remote from said substrate; a base; a first pedestal mounted on said base for supporting said substrate; means securing said oscillator element to said first pedestal, said oscillator element being supported by said first pedestal at an end portion of said substrate remote from said plurality of prongs whereby said plurality of prongs remain free to oscillate, and said substrate being disposed with one of its major surfaces secured to said first pedestal by said means securing said oscillator element; and a second pedestal mounted on said base and positioned beneath the remote end of said beam lead portion of said at least one metallic electrode, said second pedestal having a height extending from said base to the remote end of said beam lead portion for supporting the same and for bearing loads developed when connection is made with said beam lead portion.
Claim 2
Dependent Claim
246 words
The combination comprising: an oscillator element comprising an elongated substrate having a pair of opposed major surfaces and a plurality of oscillatable parallel prongs extending in a longitudinal direction therefrom, and a plurality of metallic electrodes on at least one of said major surfaces, at least one of said metallic electrodes including a unitary beam lead portion extending away from an beyond said substrate in a longitudinal direction therefrom generally parallel to said at least one major surface on which said at least one metallic electrode is disposed and away from said plurality of prongs, said beam lead portions having a remote end remote from said substrate; a base; a first pedestal mounted on said base for supporting said substrate; means securing said oscillator element to said first pedestal, said oscillator element being supported by said first pedestal at an end portion of said substrate remote from said plurality of prongs whereby said plurality of prongs remain free to oscillate, and said substrate being disposed with one of its major surfaces secured to said first pedestal by said means securing said oscillator element; and a second pedestal mounted on said base and positioned beneath the remote end of said beam lead portion of said at least one metallic electrode, said second pedestal having a height extending from said base to the remote end of said beam lead portion for supporting the same and for bearing loads developed when connection is made with said beam lead portion.
Claim 3
Dependent Claim
27 words
The combination according to claim 1, further comprising: a resilient pad disposed between said first pedestal and said substrate for protecting said oscillator element against mechanical shocks.
Claim 4
Dependent Claim
99 words
The combination according to claim 1: wherein at least one of said electrodes is disposed on the major surface of said substrate which is secured to said first pedestal; wherein said first pedestal is electrically insulative and includes a conductive pin extending therethrough and contacting said at least one electrode disposed on the major surface secured to said first pedestal; and wherein said securing means comprises a conductive adhesive for electrically connecting said at least one electrode with said conductive pin extending through said first pedestal, whereby said conductive pin comprises a terminal for said at least one electrode.
Claim 5
Dependent Claim
43 words
The combination according to claim 1: wherein said second terminal is electrically insulative and includes a conductive pin extending therethrough and contacting said beam lead portion and making electrical connection therewith, whereby said conductive pin comprises a terminal for said beam lead portion.
