Abstract

In a mounting board, two through-holes are formed which are used for inserting both ends of a supporting member for a vibrator. On a surface of the mounting board, a ground conductor pattern is formed. In the ground conductor pattern, two portions of arcs, where the ground conductor pattern is removed, are formed on respective peripheries of the two through-holes. Furthermore, on the mounting board, two connecting conductor patterns are formed on surfaces of portions defined by the two through-holes and so on, so as to extend from the ground conductor pattern. Both ends of the supporting member for the vibrator are respectively inserted into the two through-holes and soldered to two connecting conductor patterns.

Claims

1. A supporting structure for a vibrator wherein the vibrator, provided with a supporting member, is supported, comprising:

a mounting board having first and second surfaces and having a through-hole for inserting said supporting member;

a ground conductor pattern formed on said first surface of said mounting board; and

a connecting conductor pattern extended from said ground conductor pattern on said first surface and formed on said second surface of a portion of said mounting board defined by said through-hole and said connecting conductor portion surrounding said through-hole, said supporting member is soldered to said connecting conductor pattern,

wherein a suppressed heat release portion, where said ground conductor pattern is removed, is provided to partially surround a periphery of said through-hole, said suppressed heat release portion for suppression of heat released when solder is applied to said supporting member.

2. A supporting structure for a vibrator according to claim 1, wherein said suppressed heat release portion is formed in an arc.

3. A supporting structure for a vibrator according to claim 1, wherein said suppressed heat release portion is formed in an approximate C-shape.

4. A supporting structure for a vibrator according to claim 1, wherein said suppressed heat release portion is formed in an approximate U-shape.
