Abstract
The utility model relates to a quartz-crystal resonator with a thermistor, which comprises a substrate, a quartz crystal and a thermistor. The upper surface of the substrate is provided with a first frame type piece. A first space is formed by the inner frame of the first frame type piece and the upper surface of the substrate. The lower surface of the substrate is provided with a second frame type piece. A second space is formed by the inner frame of the second frame type piece and the lower surface of the substrate. The substrate positioned within the first space is provided with a first electrode part. The substrate positioned within the second space is provided with a second electrode part. The first electrode part is connected with the quartz crystal within the first space, and the second electrode part is fixedly provided with the thermistor within the second space. The first frame type piece is hermetically and fixedly provided with a cover body. Due to the adoption of the technical scheme of the utility model, the miniaturization of the quartz-crystal resonator is realized. The first space and the second space are separated through the substrate. Therefore, even at a high temperature, gases evaporating from the conductive materials of the electrode parts are not likely to adhere to both the quartz crystal and the thermistor.
Description
Technical field
