第11頁 55624〇 行切7^(1)產生接點的熔著现象，但藉由本發明之構造， 可減輕熔著程度。其理由説明如下。藉由開關機構15的切 入動作，首先活動側電弧接觸件8&會抵接於固定側電弧接 觸件4a，而電流則流通於雨接觸件之間。 藉由切入時的碰撞反弹，兩接觸件之間會稍微分開， 而流經該間距的電流將產生電弧，而該電弧的高溫則會溶 融兩接觸件之表面。在該狀態下’兩接觸件再度抵接時’ 在電弧消失時，接觸件表面的烙融部會因冷卻而產生熔著 現象。在其對策上，一般多使用難以熔融於接觸件的銀合 金接點。 本發明之構成中，在導通（0N) /關斷（0FF)時因活動件 7係以可擺動之方式形成，活動側電弧接觸件8a抵接於固 定側電弧接觸件4a時的電流係由於透過第1電阻體31以及 第2電阻體32加以限制，因此可減弱產生熔著的電弧能 海。即使在固定側電弧接觸件4a與活動側電弧接觸件8a的 抵接部有熔著現象，由於活動件7係以該抵接部為支點而 將^舌動接點6朝逆時鐘方向壓下直到與固定接點3相接觸為 止’因此抵接部會因槓桿作用而使溶著之處產生剝離。然 後，當活動接點6與固定接點3 —接觸，電流會往電阻較少 $ ^動接點6與固定接點3轉移，之後，因固定側電弧接觸 4a與活動側電弧接觸件8a的抵接部形成分離狀熊故該 不會產生電弧，同時也不會產生因兩接觸二 W起的耗損。Page 11 55624〇 Line cutting 7 ^ (1) produces the welding phenomenon of contacts, but with the structure of the present invention, the degree of welding can be reduced. The reason is as follows. By the cut-in operation of the switching mechanism 15, first, the movable-side arc contact 8 & abuts against the fixed-side arc contact 4a, and a current flows between the rain contacts. By the collision bounce when cutting in, the two contacts will be slightly separated, and the current flowing through the gap will generate an arc, and the high temperature of the arc will melt the surfaces of the two contacts. In this state, 'when the two contacts come into contact again' When the arc disappears, the soldering part on the surface of the contact may be fused due to cooling. For countermeasures, silver alloy contacts that are difficult to melt into contact pieces are generally used. In the structure of the present invention, the movable member 7 is formed in a swingable manner during the ON (0N) / off (0FF), and the current when the movable-side arc contact 8a contacts the fixed-side arc contact 4a is due to The restriction is made by the first resistor 31 and the second resistor 32, so that the arc energy sea where fusion occurs can be reduced. Even if there is a welding phenomenon at the contact portion between the fixed-side arc contact 4a and the movable-side arc contact 8a, since the movable member 7 uses the contact portion as a fulcrum, the movable contact 6 is pressed in the counterclockwise direction. Until it comes into contact with the fixed contact point 3 '. Therefore, the contact portion may be peeled off due to the leverage. Then, when the movable contact 6 is in contact with the fixed contact 3, the current will be transferred to the lower resistance. The moving contact 6 and the fixed contact 3 will be transferred. The contact part forms a separated bear, so no arc will occur, and no loss will be caused due to two contacts and two W.
