Furthermore, it is related to the support structure of crystal resonators, which are widely used in telecommunications and other fields as resonators with high sharpness (Q), and has an extremely good holding function and has many superior effects compared to conventional ones.

Crystal oscillators using this type have high frequency stability and are used as frequency standards, main oscillators of transmitters, crystal clocks, etc., and due to their high Q function,
It is well known that it is used as a filter with sharp cutoff characteristics. When this type of crystal resonator is used, for example, as a component of an electric circuit, it is generally commercialized with a configuration as shown in FIG.

多くの欠点があつた。 The above is an overview of the configurations of crystal resonators that have been generally commercialized in the past, but various drawbacks have been pointed out to the above-mentioned structures as described below. That is, as shown in Fig. 3, since the periphery of the crystal oscillator e is held between the windings of the support d and held under pressure, the clamping force from the windings tends to act as a torsional force, and moreover, it is the most powerful in terms of strength. There was a problem in that the crystal resonator e was likely to be damaged because it acted from the direction of the weak plate thickness. In addition, the wire of support d and the conductive foil film a of crystal resonator e are bonded using a conductive adhesive, but since the winding circle of support d is small, the adhesive may extend over the circular surface more than necessary. It stuck and made workability worse. Furthermore, the distance between the windings of the support d tends to be uneven, and the thickness of the vibrator varies depending on the required frequency, so it is impossible to clamp a thick vibrator, so the support There were many drawbacks, such as the fact that the winding diameter could not be made very small, which made it difficult to obtain the frequency characteristics of the vibrator.

であつた。 Therefore, as a solution to this problem, a pair of plate-like supports has been proposed in which a slit is provided in an elastic plate such as phosphor bronze or nickel silver, into which a part of the periphery of the crystal resonator e is inserted. Because of its excessive rigidity, it is susceptible to lateral vibration, and when impact force is applied, it can break the crystal oscillator. It also has poor temperature characteristics, and is susceptible to burrs caused by etching or punching when forming slits on the plate surface. This method was unsatisfactory due to problems such as scratches on the surface of the vibrator.

No. 52472 is proposed. This proposed holding device for a crystal resonator has a pair of circular coil parts formed in such a way that their circumferential sides are brought into contact with the tip of a support member for the crystal resonator under a predetermined pressure, and the support member is Two pieces were planted at a predetermined distance apart so as to be located in a straight line, and the peripheral edge of the plate-shaped crystal oscillator was sandwiched between the coil contact portion of each support member and held under pressure from the plate thickness direction. It is something. With this holding device, it is possible to prevent damage to the crystal resonator due to torsional force, but in order to make this possible, it is possible to prevent damage to the crystal resonator due to torsional force. It is necessary to bring the pair of circular coil parts into contact with the vibrator plate surface at one point on the front and back sides of the crystal vibrator and apply pressure. If the abutting positions of the front and back surfaces of the pair of circular coil parts are misaligned, a torsional force corresponding to the distance of the misalignment and the clamping force will act on the plate surface of the crystal resonator. Therefore,
The shape and positional relationship of the pair of circular coil parts formed at the tip of the support member must be strictly controlled so that they always come into contact with the crystal resonator plate surface at one point on the front and back sides of the crystal resonator plate surface. However, there is a problem in that the crystal resonator and the pair of circular coil parts are required to be directly facing each other in position, and their manufacturing requires precise processing accuracy and mounting accuracy. Various problems related to such torsional force cannot be avoided as long as the conventional crystal resonator support structure in which the plate-shaped crystal resonator is sandwiched and held under pressure from the thickness direction thereof is employed.

持するものである。 Figure 4 is an example diagram showing the structure of one support for supporting a crystal resonator, which is composed of a set of two.
Based on the reference that the illustrated position of the crystal oscillator e in FIG. 4 and FIG. 6 is the front, FIG. The support 1 is made by bending the wire 2 so that both ends are semicircular and both sides are parallel, as shown in FIG. A cavity 3 in the shape of a flat elongated hole is formed with a wide slit width. The present invention uses a set of two wires 2 on which such a slit support 1 is formed,
As shown in FIG. 6, a plate-shaped crystal resonator e is supported.

構成したものである。 That is, two wires 2, each having a slit support 1, 1' shaped as described above formed at its tip,
2' are wound around the lead terminals b, b' on the base at a predetermined interval determined from the size of the crystal resonator e, and the holes 3 of each slit support 1, 1' are The slit supports 1 are arranged to face each other in a straight line, and the slit supports 1,
The crystal oscillator e is held between the slit supports 1 and 1' by inserting the left and right peripheral edges of the plate-shaped crystal oscillator e into each of the cavities 1'.

とを防止することができる。 With this configuration, the slit support 1,
The crystal oscillator e inserted into each cavity 3 of 1' is supported at four points by contacting the slit supports 1 and 1' only at the upper and lower edges of each cavity 3, and the wires 2 and 2 The crystal oscillator e is held under pressure from the left and right directions by the elastic restoring force in the direction parallel to the plate surface of the quartz crystal oscillator e, which is generated when the quartz crystal oscillator e is pushed apart from side to side. Therefore, according to the present invention, no force acts from the thickness direction of the crystal resonator, which is the weakest in terms of strength, and the clamping force in the direction parallel to the plate surface of the crystal resonator, which is strongest in terms of strength, is maintained. Since the crystal resonator is held only by this, it is possible to prevent the crystal resonator from being damaged by torsional force based on the clamping force acting from the plate thickness direction as in the conventional case.

きる。 FIG. 5 shows another example of the shape of the slit support formed at the tip of the wire 2. That is, the slit support 6 in FIG. 〓 is narrowed down. When using this shaped slit support 6, it is possible to pinpoint adhesive the conductive foil films A and A' on the surface of the crystal resonator e at the apex position of the slit support 6 bent in a dogleg shape. , the electrical characteristics can be further improved.

のである。 The present invention has the structure and operation as explained above, and eliminates the need for a clamping force from the thickness direction of the crystal oscillator, which is the weakest in strength, when holding the crystal oscillator, and is the strongest in terms of strength. Since the crystal resonator is clamped and held only by the clamping force in the direction parallel to the plate surface, in principle there is no longer any torsional force acting from the thickness direction of the plate, and therefore the torsional force is reduced as in the conventional case. This eliminates the risk of damaging the crystal oscillator, and eliminates the need for any special structure or device to eliminate torsional force.
This has the excellent effect of providing a support structure for a crystal resonator that is simple in structure and has an excellent holding function.

である。 In addition, the slits can be freely set according to the thickness of the vibrator, making it easy to work with.Not only is it easy to obtain the frequency characteristics of the vibrator, but its temperature characteristics are also good, and since it uses wire material, This material is much more effective than conventional materials, as it does not produce burrs when forming slits like plate materials, does not damage the crystal plate, and is useful for protecting the crystal.
