ッケージ手段の一例を提供するものである。The crystal oscillator in a quartz watch requires a relatively large amount of space including the package, making it a necessity for smaller watches. Therefore, in order to reduce the size of the crystal resonator itself, even resonators with a plate thickness of about 0.1 to 12 m1 are appearing by etching the crystal pellet. However, from a comprehensive perspective, these resonators can be made more compact by effectively pancaging them, and the present invention provides an example of packaging means that is compact, low cost, and has a high degree of N. It is something.

端子７等で形成されている。Conventionally, as shown in Fig. 1, a crystal resonator has a structure in which power is supplied from the outside and the crystal resonator 5 is supported by terminals 7 and lead wires 8, which also serve to support the crystal resonator 5. Also, some electrodes are connected to the outside using a thin wire 6 using a technique such as wire bonding. Also thin line 6
A structure using a leaf spring instead of zero is also used. Furthermore, when the thickness of the crystal oscillator 5 is reduced to about cti~α2, these terminals 7 should be

0 is provided, and the sound of electrical continuity with the outside is achieved through the terminal 7 by wire bonding. However, in all of these structures, since the terminal 7 uses a wire, space efficiency is poor, and the structure is also complicated, resulting in high cost. The present invention is intended to solve these drawbacks, and will be explained according to a specific embodiment of the present invention. In FIGS. 6a and 6b, FIGS. It is formed of a glass 12, a plug frame 15, a plate-shaped terminal 7 made of a material having an expansion coefficient close to that of glass, such as copal, and the like.

子７は、一体部品であるため第５図に示す状態で見た時
明らかなように端子面７ｃｌ。Here, a specific example of the manufacturing method of the crystal resonator according to the present invention will be explained one by one. As shown in FIG.
The terminal 7 is made of an integral part, and the terminal 7 is passed through a part made of a sintered material made of glass 12, etc., and then heated and welded to form a two-lug so that airtightness can be maintained. After that, by cutting the continuous part 7a of the terminal, each can be used as an independent terminal.To attach the crystal resonator, use the connection surface on the side of the bottom lead terminal of the resonator as shown in Figure 5. It is fixed to 7b by means such as soldering and soldering, and is then sealed in a vacuum in the case 11 to complete the assembly. That is, since the terminal 7 is an integral part, the terminal surface 7cl is clearly visible when viewed in the state shown in FIG.

具の精度に左右されて、小型の１ラグは作りにくかった

という利点をもっている。Since the parallelism of 7θ and the center-to-center distance of 14 can be compensated for, high precision can be achieved, making it possible to directly attach a crystal resonator to the terminal connection surface 7b in FIG. Since these components were commonly used, it was difficult to make one small lug because each one had to be positioned independently, which increased the number of man-hours and depended on the accuracy of the jig. However, in the present invention, the terminal 7 can be Since it can be made as a press-cut part from a plate-shaped member, it has the advantage of being compact with high tK and high precision.

余分なスペースが増加し、水晶振動子ユニツトとして大
型化する問題がある。Further, the connection surface 7b of the lead terminal 7 is bent into a stepped shape,
The tuning fork crystal oscillator 5 is configured to be located approximately at the center of the cylindrical case 11. If the tuning fork crystal oscillator deviates from the center of the cylindrical case, the two will easily come into contact with each other in the event of an impact.
The case diameter is determined by estimating the total safety at the point where the dimension between the camera element and the case is the smallest, but such a configuration inevitably increases extra space and has the problem of increasing the size of the crystal resonator unit. .

るものである。The two lead terminals that partially penetrate the plug also had to pass through on a line passing through the center of the two lugs in order to provide symmetry between the front and back sides. In the present invention, the tuning fork type crystal resonator is brought to the center of the cylindrical case by bending a part of the lead terminal into a stepped shape, so that all of the above-mentioned requirements can be met. It is possible to achieve miniaturization.

It is possible to package an ultra-small crystal resonator in a space-efficient manner, and it is easy to achieve precision parts, which improves airtightness, which is good quality.It is also economical because the number of parts is reduced, and by using pressed parts, the system is improved. It has excellent practicality as it can be mass produced.
