本考案は、プリント基板に実装するのに適した
小型圧電振動子に関する。[Detailed Description of the Invention] [Technical Field of the Present Invention] The present invention relates to a small piezoelectric vibrator suitable for mounting on a printed circuit board.
［従来技術の説明］

扱いが不便である。[Description of the Prior Art] Among piezoelectric resonators, crystal resonators in particular are widely used as frequency sources and clock sources.
Among these crystal oscillators, small-sized tone-shaped oscillators, long-side vertical oscillators, etc. have cylindrical containers and are miniaturized, making them suitable for mounting in watches and the like. However, it is too small to be used in ordinary printed circuit boards and is inconvenient to handle.

扱いがしにくく、また断線し易い欠点がある。 FIG. 1 shows a hermetically sealed crystal resonator 1 used in the present invention. It has an elongated cylindrical shape,
The lead wires 2, 2' drawn out from the inside are also thin and difficult to handle, and have the disadvantage of being easily broken.

ことは難しい。 Therefore, in order to eliminate this drawback, a structure has been considered in which a new terminal is provided after being attached to an insulating substrate or the like. Figures 2a and 2b show such examples; in Figure 2a, a conductive pattern 4 is formed on an insulating substrate 3, a hermetically sealed crystal resonator 1 is fixed on one main surface, and the other main surface is fixed. Terminals 5 and 5' are pulled out from the terminal. FIG. 1B shows a chip type device, in which a conductive portion 7 for fixing lead terminals 2, 2' of the crystal resonator 1 is provided on an insulating substrate 6. The conductive portion 7 extends from the main surface to the side surface of the insulating substrate 6 and functions as a lead-out portion. However, such a vibrator is expensive because it uses an insulating substrate made of epoxy or the like, and it also requires many man-hours, which increases the cost. Particularly in the case of a chip type, heat resistance is required and a ceramic substrate is used, making it difficult to manufacture at a low cost.

The lead terminal is connected to a lead terminal having a diameter different from that of the lead terminal, and the piezoelectric vibrator and the part connected to the lead terminal having a different diameter from the lead terminal are molded with mold resin. .

Fix it with solder or spot welding. This fixed lead terminal uses a conductor wire that is thicker than the diameter of the lead terminals 2, 2' of the cylindrical crystal resonator 1. After the thick lead-out terminals 8, 8' are fixed, they are housed in the case 9. The case may be insulative or conductive such as metal. This case 9

がし易い構造になつた。[Effects of the present invention] The present invention does not use an expensive insulating substrate and requires no man-hours, so it can be manufactured at low cost. Further, although the thickness of the lead terminals and the pitch between the two lead terminals are fixed in the case of an insulating substrate, the present invention has the advantage that they can be freely changed. Additionally, the lead terminals can be fixed with adhesive, making the structure easier to handle.
また、水晶振動子のリード端子の断線、切断等

The most stable fixation and support can be achieved when the ratio of the lead terminal to the lead terminal is about 0.5. However, it has been found that the effect of the present application can be sufficiently achieved if the lead terminal is slightly thicker than the lead terminal, 0.75 mm or less.
