て作業性を低下する問題があった。In addition, as shown in FIG. 7, especially when taping the crystal resonator 1 to which the insulating plate 7 is attached, the accuracy of the position i12 of the crystal resonator 1 relative to the carrier tape 10 is deteriorated, resulting in work efficiency. There was a problem with the decline.

題があった。In reality, taping is performed by keeping this distance d1 constant using an automatic attachment device. 17. If the insulating plate 7 as described above is attached to the bottom surface of the metal base 3, the carrier 1
The distance d2η between the side end a of the aperture 7-10 and the insulating plate 7 is equivalently constant (FIG. 8). Only (7, in reality,
The insulating plate 7 may be attached obliquely to the bottom surface of the metal base 3, for example, during insertion or during subsequent transportation and operation. Therefore, in such a case, the distance between the side edge a and the insulating plate 7 may be incorrectly measured, and the distance between the side end a and the insulating plate 7 may be incorrectly measured, and the distance between the side edge a and the metal base 3 may be measured at a constant value d according to the specifications.
1 (Figure 9). As a result, there was a problem in that the positional accuracy of the crystal resonator 1 with respect to the carrier tape 10 was deteriorated, and the reliability in the case of taping was compromised.

詳細な説明する。(Means for Solving the Invention) The present invention provides an insulating plate by arranging slits in parallel from one side to be inserted from a direction perpendicular to the lead wires led out from a metal base, and using this insulating plate. The solution is to configure a crystal oscillator. Hereinafter, the present invention will be explained in detail.
(実施例)
第1図は本発明の一実施例を説明する水晶振動子の図で

てその説明は簡略する。(Example) FIG. 1 is a diagram of a crystal resonator explaining an example of the present invention. Note that the same parts as those in the previous embodiment drawings are given the same numbers and the explanation thereof will be simplified.
水晶振動子1は、前述同様に一対のリード線が導出した
金属ベース3上に立設したサボーク4に水晶片2を保持
し、金属カバー5を封着する。そして、金属ベース3の
底面には絶縁板12が装着される。In the crystal resonator 1, a crystal piece 2 is held on a savok 4 erected on a metal base 3 from which a pair of lead wires are led out in the same manner as described above, and a metal cover 5 is sealed. An insulating plate 12 is attached to the bottom surface of the metal base 3.

ス3の底面に装着する。The insulating plate 11 is made of, for example, flat polyester and has approximately the same shape as the bottom surface of the metal base 3. Then, a pair of notches 12 are provided in parallel from one side in the longitudinal direction. This cut 12 is approximately V-shaped, and the open end of the letter 7 is on one side. Then, the open end has a width larger than the diameter of the lead cotton 6 and is used as a guide portion 13. Further, the closed end is formed into a narrow groove smaller than the diameter of the lead wire 6 to serve as the fixing portion 14 . Then, the insulating plate 11 is attached to the bottom surface of the base 3 by inserting the guide part 13 from a direction perpendicular to the direction in which the lead wires 6 are drawn out and pushing in the fixing part 14.
したがって、このようなものでは、従来例のように小さ

を高めろことができろ。In particular, when taping the crystal resonator 1, for example, after making the distance mdt between the side end a of the carrier tape 10 and the metal base 3 constant as usual (see FIG. 7 above),
Since the insulating plate 11 may be mounted from the orthogonal direction as described above, problems such as misalignment of the crystal resonator 1 will not occur. Therefore, it is possible to improve its reliability even in such a case.

することが期待できる。(Other matters) In the above embodiment, the pair of notches 1 of the insulating plate 1
2 is approximately V-shaped and the fixed part 14 at the closed end is simply a thin groove, but for example, as shown in FIG. 2, the fixed part 14 is made into a narrow groove 15 bent from the closed end, The lead wire 6 may be guided to further prevent its separation 11-. In addition, as shown in FIG.
For example, the tip may be made into an arc shape to prevent the lead wire 6 from coming off from one side. In addition, although the narrow groove that forms the figure 7-shaped fixing part 14 is made smaller than the lead latitude, it is not necessary to reduce its diameter when, for example, a crystal resonator is mounted on a circuit board. You can decide accordingly. In addition, as shown in FIG. 4, a similar cut is provided between a pair of parallel cut portions 12 to form an absorption groove 17, so that, for example, the distance between the fixed portions of the insulating plate 11 may have an error due to manufacturing or changes over time. Even if this error occurs, the error may be absorbed. The shape of the cuts 12 in this case does not pose any particular problem, and a plurality of cuts 12 may be formed from both sides. In this case, it is expected that the external force applied to the crystal resonator 1 through the lead cotton 6 will be reduced, thereby preventing deterioration of its characteristics.

A device in which the insulating plate 11 is inserted and mounted from the notch 12 from the perpendicular direction is included within the technical scope of the present invention.

Since it is attached, it is possible to improve workability and increase reliability especially when taping a crystal resonator, and the practical effect is very large.
