れる巻線用ボビンに関し、特に、巻線に与える熱、振動
による悪影響の極く少ない巻線用ボビンに関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a winding bobbin used for a bobbin around which an optical fiber for a sensor of an optical fiber gyro is wound, and more particularly to a winding bobbin which has very little adverse effect due to heat and vibration applied to the winding. Related to wire bobbins.

った。2. Description of the Related Art A conventional example of a bobbin for winding will be described with reference to FIG. FIG. 2 is a diagram showing a cross section of a conventional winding bobbin. Reference numeral 1 denotes a bobbin portion of a bobbin for winding, which was made of a synthetic resin, metal or other single material.

Even if it is not apparently designed to have a shape and structure that has any adverse effect on the function of the winding itself, it will always be used as a winding when the winding is actually incorporated into the optical structure. It may not always show good optical properties.

蒙るのである。[0004] The reason why such a winding formed by winding the winding frame portion 1 does not always show good optical characteristics as a winding when actually incorporated in an optical system structure. It turns out that the reason is that the winding frame 1 shows the temperature characteristic after all. Further, it has been found that even when vibration is applied to the winding bobbin or the optical system structure including the same, the optical characteristics of the winding deteriorate. In particular, in the case of a winding formed by winding a fine wire having extremely low mechanical strength on a winding bobbin, the optical and mechanical properties are determined by expansion and contraction due to heat transmitted to the winding and vibration applied. It has a greater impact.

れば今度は断熱特性の保証は得られないことになる。If the winding bobbin 1 is made of a material that has good temperature characteristics and absorbs vibration applied to the winding, the winding bobbin will always maintain the optical characteristics of the winding. It can be good. However, since the winding bobbin 1 of the winding bobbin as described above is made of a single material, if a material having excellent heat insulating properties is selected for the sake of improving the temperature characteristics, the heat will be reduced. Although the expansion and contraction of the winding due to the above is reduced, the vibration absorption characteristics are not always guaranteed. Conversely, if the material of the winding frame portion 1 is selected with priority given to the vibration absorption characteristics, Means that the insulation properties cannot be guaranteed.

も実験により確認された。The above-described winding bobbin is fixed to a circuit board or other mounting plate by the bobbin fixing support 3. Therefore, heat is introduced and transmitted from the outside to the winding via the bobbin fixing support 3. Here, in the bobbin for winding according to the present invention, an intermediate layer 2 made of a hard rubber which exhibits heat insulation, vibration absorption and thermal expansion difference absorbing action is interposed between the winding frame 1 and the bobbin fixing support 3. Therefore, the heat insulation effect of the intermediate layer 2 reduces the delay of the heat introduced into the fixed support portion 3 from reaching the winding, thereby reducing the adverse effect of the heat on the winding. During this time, since the bobbin fixing support 3 thermally expands, a difference in thermal expansion occurs between the bobbin fixing support 3 and the bobbin 1 and the bobbin 1 is supposed to be deformed. The thermal expansion of the bobbin fixing support portion 3 is absorbed by the thermal expansion difference absorbing action of
Will not be directly affected. Therefore, the effect of thermal expansion on the winding is reduced. Experiments have also confirmed that the change in the optical characteristics of the winding when the vibration is applied to the winding bobbin or the mounting plate on which the bobbin is mounted is reduced.

イバ巻線用ボビンを構成することができる。As a result of the bobbin fixing support 3 being made of a material having high thermal conductivity, the temperature distribution of the entire bobbin fixing support 3 including the flange 31 is always uniform. The bobbin section 1 is fitted and enclosed in the bobbin fixing support section 3 having a uniform temperature distribution, including the flange section 11, so that the bobbin fixing support section 3 moves from the bobbin fixing support section 3 to the bobbin fixing section 3. Is uniformly conducted over the entire body including the collar portion 11 of the bobbin section 1, and the temperature distribution of the bobbin section 1 is also made uniform. Therefore, heat is uniformly transmitted to the entirety of the optical fiber coil wound around the winding frame 1 including the coil end surface that comes into contact with the flange 11 of the winding frame 1. From the above, in combination with the fact that the winding frame 1 is made of a material having a small coefficient of thermal expansion, the distortion of the optical fiber coil due to the non-uniform temperature distribution is reduced, and the optical characteristics of the optical fiber are reduced. Will be good. Then, the winding frame 1 having the flange 11 is formed of invar, the intermediate layer 2 having the flange 21 is formed of hard rubber, and the bobbin fixing support 3 having the flange 31 is formed of aluminum. An optical fiber winding bobbin having particularly good optical characteristics can be formed.
