ABSTRACT:
A piercing fluid-tight connector device for use with ultra-low temperature cable for supplying external electrical current to a motor of a pump located in an accumulation tank or vessel. An insulating sleeve having a flange with a female thread at an inner peripheral surface of the sleeve is threadingly engaged with an electrically conductive rod with a male thread thereof. A sealing member is interposed between the sleeve and rod. The coupled sleeve and rod extend through an aperture in a main metal body with the flange of the insulating sleeve and the metal body being in contact with each other, preferably through a packing, so as to provide a fluid-tight structure.
