ABSTRACT:
A terminal structure (9) for a motor-driven pump (1) to be disposed in a storage tank for a liquid such as liquefied ammonia or the like interconnects a motor-side terminal element (30) of a first conductor cable (29) for supplying an electric power to a motor (12) of the motor-driven pump and a power source-side terminal element (36) of a second conductor cable (35) for supplying the electric power from an electric power source. The terminal structure (9) has a hollow tubular housing (25) accommodating a conductor (41) and having upper and lower ends (37, 31) through which the power source-side and motor-side terminal elements (36, 30) extend into the housing and are electrically connected to the conductor (41) therein. The motor-side terminal element (30) is sealingly connected to the lower housing end (31) by a sealing mechanism (28, 28A) which utilizes sealing ring (33A, 33B; 133A, 133B) of a metal while the power source-side terminal element (36 ) is sealingly connected to the upper housing end (37) by a sealing mechanism (27) which utilizes gaskets (26A-26C).
