Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a crystal resonator assembly jig, and more particularly to a crystal resonator assembly jig for assembling a crystal plate into a crystal resonator.

[Conventional technology]

Inserting a small crystal plate into a predetermined position in a crystal resonator involves difficult work.

4 and 5 are perspective views for explaining a conventional method of assembling a crystal resonator.

As shown in FIG. 4, a pair of supports 12 and 1 are attached to the base 11 of the crystal resonator 10.
3 to the outside, hold the crystal plate 14 with tweezers, etc., and insert the elongated holes 12a, 13 of the supports 12, 13.
a and is assembled as shown in FIG.

[Problem that the invention attempts to solve]

The conventional method for assembling the crystal resonator described above is to manually spread the pair of support plates 12 and 13 of the crystal resonator 10 with one hand, and pinch the crystal plate 14 using tweezers with the other hand. , support plate 1
Since the crystal plate 14 is attached to the elongated holes 12a and 13a of the tweezers 2 and 13, there is a problem that the crystal plate 14 may be thrown off from the tweezers and damaged if the user is not skilled.

An object of the present invention is to provide a crystal resonator assembly jig that allows even an unskilled worker to easily assemble the crystal resonator.

[Means for solving problems]

The crystal oscillator assembly jig of the present invention has a pair of support plates each having a long hole into which a crystal plate is inserted, and a guide surface for defining the position of a quartz crystal holder, which is fixed to a base. a guide portion, a shaft that supports the crystal plate with one end surface aligned with the elongated hole portion and whose other end surface is fixed to the base; and a pair of support plates that are slidably fitted to the shaft. and a moving axis that widens the distance between the crystal plates to be slightly larger than the outer periphery of the crystal plate.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings. FIGS. 1a and 1b are a plan view and a sectional view taken along the line A-A' of an embodiment of the present invention.

This will be explained with reference to FIGS. 1a and 1b.

The shaft 2 is a circular shaft fixed to the base 1. The moving shaft 3 has an annular projection 3a at one end of the cylindrical outer circumference.
is provided, and the inner surface of the through hole is slidably fitted onto the shaft 2. The guide portion 4 is fixed to the base 1, and makes the end surface of the shaft 2 and the end surface of the moving shaft 3 coincide with each other when the protrusion 3a of the shaft 2 and the wall surface 4a are in contact with each other.

FIGS. 2a and 3b and 3a and 3b are plan views and sectional views taken along lines B-B' and C-C' for explaining this embodiment.

As shown in FIG. 2, the distance between the support plates 12 and 13 of the crystal resonator 10 is widened by the moving shaft 3, and the crystal plate 14 is set on the plane of the moving shafts 2 and 3.

Next, as shown in FIG.
When moving in the b direction, the crystal plate 14 moves towards the support plate 1.
2 and 13 are inserted into the long holes 12a and 13a.

In this way, the crystal plate can be inserted into the elongated holes of the pair of support plates of the crystal resonator supported by the guide part by sliding of the moving shaft.

[Effect of idea]

As explained above, the present invention allows the crystal plate to be inserted into the long holes of the pair of support plates of the crystal resonator by sliding the moving axis, so even an unskilled worker can easily This has the effect of facilitating assembly work.
