Apparatus and method for connecting first electrically conductive tube and second electrically conductive tube

The present invention relates to an apparatus and a method for connecting a first electrically conductive tube and a second electrically conductive tube. The apparatus includes first and second electrically conductive tubes, first and second electrical isolators, and a nut. The first electrical isolator has a central passageway. The first electrically conductive tube has a flared end disposed around the first electrical isolator. The flared end includes external threads. The second electrically conductive tube has an outer flange. The second electrical isolator is disposed around the second electrically conductive tube and engages the outer flange. The nut is disposed around the second electrically conductive tube and engages the second electrical isolator. The nut includes internal threads corresponding to the external threads of the flared end of the first electrically conductive tube. 本发明涉及用于连接第一导电管和第二导电管的装置和方法。一种装置包括第一和第二导电管、第一和第二电绝缘器以及螺母。第一电绝缘器具有中心通道。第一导电管具有围绕第一电绝缘器设置的扩口端。扩口端包括外螺纹。第二导电管具有外凸缘。第二电绝缘器围绕第二导电
