Abstract
Description
【発明の詳細な説明】 本発明は位置センサーの構造に関する。[Detailed description of the invention] The present invention relates to the structure of a position sensor.
従来、位置センサーとして種々のものが作られているが
、中でもａ［変換素子を用いたものが、耐久性、耐環境
性においてすぐれてお５．多くの装置に使われて釆てい
る。Conventionally, various position sensors have been made, but among them, those using a conversion element have excellent durability and environmental resistance.5. It is used in many devices.
しかし、磁電ｆ＠素子と磁束全変化させる永久磁石等を
別々に実装する為にａｍ変換素子と永久磁石等を正確に
位曹合わせして組み込むことに難点があった。However, since the magnetoelectric f@ element and the permanent magnet etc. that change the total magnetic flux are separately mounted, there is a problem in accurately aligning and assembling the am conversion element and the permanent magnet etc.
本発明によれば、磁電変換素子と永久磁石等とを一体の

作ｖｊｈ部とし、他端に永久磁石をかん合し、レバー中
間部に回転支軸を設ける。In the present invention, one end of the lever is used as a deflecting portion vjh so that the opposing position of the eleven magnetic transducer elements and the permanent magnet, each having an output terminal that can be directly soldered to a circuit board, changes as the lever rotates. A permanent magnet is engaged with the other end, and a rotating shaft is provided in the middle of the lever.

ーの両ｔｉｌｌｌをはさむようにスイッチベースからテ
ンシ冒ンアームが一体成形されている。The bearing portion of the rotational support shaft is formed with a partial opening so that the magnetoelectric transducer can be directly fitted into a switch space that is integrally molded or bonded. Further, a tension arm is integrally molded from the switch base so as to sandwich both tills of the lever so that a restoring force acts on the lever when the lever is deviated.
次に本発明の実施列を示した図面を参照して、本発明の
詳細な説明する。The present invention will now be described in detail with reference to the drawings, which illustrate embodiments of the present invention.

対側に永久磁石２をはめ込み、レバー３の中間部に回転
支軸５を設ける。1 to 3, in one embodiment of the present invention, the magnetoelectric transducer 1 and the permanent magnet 2 are in opposing positions, and the lever 3
The permanent magnet 2 is fitted into the opposite side of the lever from the deflection actuating part 4 so that when one end of the lever is deflected, the permanent magnet 2 is removed from the position i facing the magnetoelectric conversion element 1, and the permanent magnet 2 is rotated in the middle part of the lever 3. A support shaft 5 is provided.
回転支軸５に対応する軸受部６は磁電変換素子１が一体
モールドされているスイッチペース７に直接はめ込める
形で開口部とともに形成されている。A bearing portion 6 corresponding to the rotational support shaft 5 is formed with an opening so that it can be directly fitted into a switch space 7 in which the magnetoelectric conversion element 1 is integrally molded.
レバー３が偏位した際に復位させる力を作動させるよう
にスイッチペースの両側からレバー３に対しテ／シ曹ン
アーム８が一体成形されている。A lever arm 8 is integrally molded with respect to the lever 3 from both sides of the switch base so as to actuate a force for returning the lever 3 to its position when the lever 3 is displaced.

子１出力は、第１図の状態と異なり、位置センサーとし
ての機能を果たす。Figure 4 shows the state when the lever is deflected by a moving object to be detected (not shown in Figure 5), and the magnetoelectric conversion element 1
Since the positions of the permanent magnet 2 and the permanent magnet 2 do not match, the output of the amm conversion circuit 1 functions as a position sensor, unlike the state shown in FIG.
本発明は以上説明したように、電磁変換素子と永久磁石
とを作動レバーを有した一対の構成にすることにより、
位置合わせや機構部への複雑な取付が省略され、信頼度
の向上と実装効率の向上が計られる効果がある。As explained above, the present invention has the electromagnetic conversion element and the permanent magnet configured as a pair with an actuating lever.
Positioning and complicated attachment to mechanical parts are omitted, which has the effect of improving reliability and mounting efficiency.
