いた。 In general, piezoelectric resonators made of crystals, especially quartz resonators, have excellent electrical properties and have long been used in communication equipment and the like that require high precision and stability. FIG. 1 is a front view showing a typical configuration of this type of crystal resonator. That is, this crystal resonator passes through a base 3 through the outer periphery of both ends of an AT-cut disk-shaped crystal piece 2 having electrodes 1 formed on both main surfaces of the plate surface, and extends onto the main surface of the base 3. It is formed by sandwiching the coiled tips of a pair of opposing lead wires 4 and joining a cover (not shown) to the periphery of the base 3 by resistance welding or the like. However, in recent years, crystal oscillators have been widely used in various consumer devices that require a reference signal source, including not only the above-mentioned communication devices but also electronic wristwatches and microcomputers. For this reason, in addition to the above-mentioned crystal resonator having a high height, it is also difficult to mount it on a circuit board using a parts feeder, etc., so it is easy to automatically attach it to mass-produced electronic equipment, and it is small and inexpensive. Something suitable for production was desired.

らず、結果として作業性の低下を招く。 By the way, in order to prevent the characteristics of a crystal resonator from deteriorating due to aging, it is necessary to ensure that not only the container 5 that encloses the crystal piece 10 is not damaged, but also the sealing of the container is never impaired. . For this reason, the pair of lids 12a,
When forming the container 5 by joining the upper surfaces of the frame portions 11a and 11b of the frame portions 11a and 11b with the adhesive 15, a pressing force is applied to the frame portions 11a and 11b in the direction indicated by q in FIG. The 15th layer is made thinner, and the bonding strength between the upper surfaces of the frame portions is increased to achieve sealing. Therefore, for example, if the amount of adhesive 15 applied is too large, the adhesive 15 will be damaged by the pressing force in the q direction, as shown in FIGS. 3b and 3c.
The excess amount protrudes from the top surface of the container 5 into and out of the container 5. In order to show this, for convenience, the lead wires 6a and 6b have been removed, and FIG. show. In the figure, the diagonal line is the excess amount 16 of the adhesive. Therefore, although the surplus 16 of the adhesive 15 may increase the bonding strength of the container 5 in some cases, in reality, the surplus 16 in the container 5 is
In addition, the excess portion 16 outside the container 5 not only impairs the aesthetics but also causes dimensional errors in the container 5 in the case of specifications with strict dimensional accuracy, causing defective products. Become. For example, if the amount of adhesive 15 applied is too small, the degree of sealing and adhesive strength of the container 5 will be impaired, resulting in unexpected damage to the container 5 and leakage. Therefore, the operator involved in hermetically sealing the container 5 must use the adhesive 1.
Careful attention must be paid to the amount of coating No. 5, which results in a decrease in workability.

4A is a perspective view, and FIG. 4B is a cross-sectional view taken along line AA' in FIG. 4A. That is, this lid body 17a is made of ceramic material, for example, like the one described above, and has a frame part 18a formed around a substantially square plate surface. The difference is that a part of the upper end surface is removed along the outer periphery to form a stepped portion 19a. In addition, 20

Further, the surplus portion 16 of the adhesive 15 remaining in the retaining groove 23 fills the inner wall of the retaining groove 23, so that the joint strength of the container 22 exceeds the joint strength determined by the upper end area of the frame, and the degree of sealing is also improved. Becomes good. Therefore, by applying a pressing force q, the adhesive 1 flowing out from the upper end surface of the frame
The surplus portion 16 of 5 does not protrude inside or outside the container 22 and cause errors in the external dimensions of the container 22, nor does it adhere to the crystal piece 10 and deteriorate its properties, and also improves the bonding strength and sealing. will not be damaged. FIG. 7 shows one lid 1 of a crystal resonator in which a crystal piece 10 electrically and mechanically connected to lead wires 6a and 6b is enclosed in a container 22 as described above.

Step portions 19a and 19b are provided in both the frame portions 18a and 18b of a and 17b to remove the excess amount of adhesive 15.
6 retaining grooves 23 were formed, but one lid body 17a
Needless to say, it is also possible to form a stepped portion 19 only on the groove and use this as a retaining groove. Also, for example, Fig. 8a
As shown in Figure b, the stepped portions 19a and 19b may be sloped to make it more difficult for the excess 16 of the adhesive 15 to protrude into and out of the container 22, or the upper end surface of the frame may be curved as shown in Figure b. The above effects can be expected even if this is applied. Further, as shown in FIG. 8c, in order to increase the bonding strength of the upper end surface of the frame, the cross-sectional shape of the projecting end of the frame may be approximately cup-shaped in order to increase the area of the upper end of the frame. The point is that the excess amount 1 of the adhesive 15 flows out from the upper end surface of the frame into and out of the container 22 due to the pressing force.
It is sufficient that the fastening portions 6 are formed on the frame portions 18a and 18b so as not to impair the bonding strength and sealing of the container 22, and may be modified as appropriate without departing from the gist of the present invention. Moreover, in one embodiment of the present invention, the lids 17a and 17b have the same shape.
Although the container 22 is formed using the above, it goes without saying that the present invention is not limited to this, and for example, cut grooves may be formed only on one lid 17a for through holes for the lead wires 6a and 6b. do not have.

Therefore, it is possible to provide a piezoelectric vibrator that has good bonding strength, prevents airtight leakage, and is suitable for automatic mounting and automatic production without impairing dimensional accuracy and electrical performance.
