【考案の詳細な説明】
本考案は小型モータの機械式ガバナスイッチにおける可
動接点部の改善に関するものである。[Detailed Description of the Invention] The present invention relates to an improvement of a movable contact portion in a mechanical governor switch for a small motor.
第１図は一般的な小型モータの機械式ガバナスイッチの
構成を示すもので、１は電機子、２は電気絶縁材よりな
るガバナ基台で、導電板３ａ、３ｂが一体モールドされ
ている。FIG. 1 shows the configuration of a general mechanical governor switch for a small motor, in which 1 is an armature, 2 is a governor base made of an electrically insulating material, and conductive plates 3a and 3b are integrally molded.
４はモータの回転数を設定する固定接点で、導電板３ａ
に取付けられている。4 is a fixed contact for setting the rotation speed of the motor, and conductive plate 3a
is installed on.
５は一端を導電板３ｂに固定した板バネで、遊端に固定
接点４に対向する可動接点６が固着されている。A leaf spring 5 has one end fixed to the conductive plate 3b, and a movable contact 6 facing the fixed contact 4 is fixed to the free end.
７は板バネ５の反接点側に固着した重錘である。7 is a weight fixed to the opposite side of the leaf spring 5 to the contact point.
以上の構威よりなる機械式ガバナスイッチにおいて、従
来は第２図に示す如く、可動接点部は板バネ５に接点６
をスポット溶接部さらに遠心力をもたせるため金属製の
重錘７をスポット溶接して構威している。In the mechanical governor switch having the above configuration, conventionally, as shown in FIG.
A metal weight 7 is spot welded to the spot welded part to further provide centrifugal force.
第２図におけるイ９９ロ、ハスポット溶接部を示す。A99B in FIG. 2 shows a haspot welded part.
この場合、スポット条件により板バネ５と金属性の重錘
７、板バネ５と接点６がはずれたりすることがある。In this case, depending on the spot conditions, the leaf spring 5 and the metallic weight 7, and the leaf spring 5 and the contact point 6 may become disconnected.
特に接点部は先に板バネ５と重錘７をスポット溶接し、
その後、接点６をスポット溶接するため、板バネ５、重
錘７の組成が変化しもろくなってはずれやすい。In particular, for the contact part, first spot weld the leaf spring 5 and the weight 7,
After that, since the contacts 6 are spot welded, the compositions of the leaf spring 5 and the weight 7 change, making them brittle and easily coming off.
また板バネ５と金属性の重錘７の間に隙間があくため、
遠心力の応答性が悪くなり、可動接点６の開閉が不安定
となる欠点があった。Also, since there is a gap between the leaf spring 5 and the metal weight 7,
There was a drawback that the responsiveness of centrifugal force deteriorated and the opening/closing of the movable contact 6 became unstable.
本考案は上記従来の欠点を改良するものである。The present invention improves the above-mentioned conventional drawbacks.
以下本考案の実施例を第３図を参照して説明すると、重
錘７は一面に接着剤を塗布した柔軟性を有するゴムにて
構威し、接着剤にて板バネ５に固定している。An embodiment of the present invention will be described below with reference to FIG. 3. The weight 7 is made of flexible rubber coated with adhesive on one side, and is fixed to the leaf spring 5 with adhesive. There is.
なお、第３図において、ａは接着剤、ｂは重錘本体であ
る。In addition, in FIG. 3, a is an adhesive and b is a weight body.
以上の構成から明らかなように本考案によればスポット
溶接部は接点と板バネの１点となり、はずれが少なくな
る。As is clear from the above configuration, according to the present invention, there is only one spot weld between the contact point and the leaf spring, which reduces the possibility of dislocation.
また板バネとゴム製の重錘は密着して固着されるため、
応答性がよくなり、可動接点の開閉が安定するなど実用
的価値の犬なるものである。In addition, since the leaf spring and the rubber weight are closely fixed,
It has great practical value, with improved responsiveness and stable opening/closing of movable contacts.
