发明内容
本发明要解决的技术问题是提供一种加工要求精度低、工艺难度小、成本低和额定电流大的固封极柱。
本发明的技术解决方案是:
一种固封极柱,具有环氧树脂壳,环氧树脂壳上部设有上出线端子,环氧树脂壳内部设有灭弧腔,灭弧腔下面设置导电杆,灭弧腔下面设有下出线端子,环氧树脂壳下部设有绝缘拉杆,所述绝缘拉杆与导电杆连接,其特殊之处是:所述灭弧腔的导电杆和下出线端子通过软连接连接,在灭弧腔和下出线端子之间设有用来支撑灭弧腔的连接支架。
本发明的有益效果是:
可增大额定电流,加工要求精度低,工艺难度小,成本较低。
附图说明
图1是发明的结构示意图。
图中:环氧树脂壳1,上出线端子2,灭弧腔3,导电杆301,连接支架4,软连接5,下出线端子6,绝缘拉杆7。
具体实施方式
    如图所示,本发明涉及的固封极柱,具有环氧树脂壳1,环氧树脂壳1上部设有上出线端子2,环氧树脂壳1内部设有灭弧腔3,灭弧腔3下面设置导电杆301,灭弧腔3下面设有下出线端子6,环氧树脂壳1下部设有绝缘拉杆7,所述绝缘拉杆7与导电杆301连接,所述导电杆301和下出线端子6通过软连接5连接,在灭弧腔3和下出线端子6之间设有用来支撑灭弧腔3的连接支架4。
