Description

[Detailed Description of the Invention] The present invention relates to a terminal board for a piezoelectric tuning fork mechanical vibrator. Piezoelectric tuning fork mechanical oscillators are most commonly used as low frequency oscillation elements and as resonant elements for mechanical filters.
The terminal board of this piezoelectric tuning fork mechanical vibrator is provided with terminals for connecting electrical signals from the outside to the mechanical vibrator, or vice versa, from the mechanical vibrator to the outside, and also fixes the mechanical vibrator. It was created as a base for

In conventional terminal boards, the part that fixes the mechanical vibrator and the part that fixes the support rubber, as shown in 4a shown in Figures 1a and 2b, are flat or have only left and right guides. It was hot. According to this, as shown in Figs. 3 and 4, the piezoelectric tuning fork was often installed in a bent state, and in some cases, accidents were likely to occur in which the piezoelectric tuning fork did not function as a mechanical vibrator.

In order to eliminate the above-mentioned drawbacks, the present invention has a terminal board shaped as shown in 4a in Figures 5a and 5b, and a tuning fork body (1, 8, 7, 2, 3 assembled in Figure 6). ) to the terminal board with high precision.

Hereinafter, the piezoelectric tuning fork mechanical vibrator according to the invention will be explained with reference to the drawings. In FIG. One end of the supporting member 2, which has an L-shape as a whole, is joined in a point contact manner by welding or the like. A square-shaped support rubber 3 is fitted into the other end of the support member 2, and this support rubber 3 forms a U-shaped support formed on the upper extension 4a of the terminal board 4. Part 5
The tuning fork element is held on the terminal board 4 with the support member 2 providing a buffer.

A plurality of terminals 6 are provided on the terminal board 4, and each terminal 6 is connected to a piezoelectric transducer 7 provided on the tuning fork element. Furthermore, a mass member 8 is attached to the upper part of each of the tuning fork elements.

As described above, this invention has the advantage that since the tuning fork body is held by the holding part 4a in the upper extension part of the terminal board 4, there is little inclination in the front, back, left and right directions, and accidents caused by conventional fixing methods do not occur. .
