本考案は強制空冷で用いるフアンの磁気シール
ドを行なうフインガーガードに関するものであ
る。[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a finger guard for magnetically shielding a fan used in forced air cooling.
従来通信機器用の冷却フアンには、危険防止の
為のフインガーガードは施されていたが、磁気シ
ールドの対策は何ら施されていなかつた。したが
つて、磁気障害の発生に対しては障害を受ける回
路素子に磁気シールドを施していたため対応が面
倒であつた。
Conventional cooling fans for communication equipment have been equipped with finger guards to prevent danger, but no magnetic shielding measures have been taken. Therefore, it has been troublesome to deal with the occurrence of magnetic disturbances because magnetic shielding has been applied to the circuit elements that are affected by the disturbance.
本考案の目的は、フアンを用いた強制空冷方式
に於いて、フアンの風量を損う事なく、モーター
から発生する漏洩磁束をシールドする手段を提供
するものである。
The purpose of the present invention is to provide a means for shielding leakage magnetic flux generated from a motor without impairing the air volume of the fan in a forced air cooling system using a fan.
上記目的を達成する為、モータ外径と同じ寸法
の磁性材料（電磁軟鉄）で作つた円板をモータの
側面に設けたことである。
In order to achieve the above objective, a disk made of magnetic material (electromagnetic soft iron) with the same dimensions as the motor's outer diameter is provided on the side of the motor.
本考案の実施例を第１図及び第２図で説明す
る。強制空冷を行う為のフアン本体１、その中の
羽根６を駆動するモータ５、モータ直径に相当す
る大きさのシールド板４も持つガード兼ステム２
及びフアンを保持するシヤーシ３、取付ネジ７よ
り構成されている。
An embodiment of the present invention will be explained with reference to FIGS. 1 and 2. A fan body 1 for forced air cooling, a motor 5 that drives the blades 6 in the fan body, and a guard/stem 2 that also has a shield plate 4 with a size corresponding to the diameter of the motor.
It also includes a chassis 3 for holding the fan, and mounting screws 7.
フアンを駆動した場合、モータ部から発生する
漏洩磁束をシールド板４で磁気シールドすると共
に、シールド板４の大きさはモータ直径相当とし
ているのでフアン風量に何等影響を与えない構造
となつている。又寸法的にもガード兼ステム２の
取り付けと変らないので、ガード兼ステム２を取
り付けている部分との互換性もある。 When the fan is driven, leakage magnetic flux generated from the motor section is magnetically shielded by the shield plate 4, and since the size of the shield plate 4 is equivalent to the diameter of the motor, the structure has no effect on the fan air volume. Also, since the dimensions are the same as those for installing the guard/stem 2, there is also compatibility with the part to which the guard/stem 2 is attached.
本考案によれば、モーター径相当のシールド板
をモータ側面に密接する事により、風量特性に影
響を与えず且つシールドの効果がある。
According to the present invention, by placing a shield plate corresponding to the diameter of the motor in close contact with the side surface of the motor, the air volume characteristics are not affected and the shielding effect is achieved.
