10 固定接点
11 可動接点
58 ガード壁
61 空気孔
A 接点装置
Claims (1)
- 合成樹脂製のハウジングと、ハウジング内の定位置に配置された固定接点と、ハウジング内において固定接点と接離可能な可動接点とを備え、ハウジング内において固定接点の周囲であってハウジングの内側面から離間した位置には、ハウジングを形成する合成樹脂材料よりも高い耐熱性を有する絶縁性材料からなるガード壁が立設されており、
前記ガード壁は、前記固定接点と前記可動接点との開極時におけるアークの発生位置よりも上方に、アーク発生時に熱エネルギにより膨張した空気を固定接点と反対側に逃がす空気孔を有することを特徴とする接点装置。
