发明名称 Current transformer
摘要 A current transformer is encapsulated in an injection molded layer of insulating material. The current transformer includes a secondary terminal assembly having individual terminals mounted on a terminal board. The terminal board is formed of a material that softens within the normal processing temperature range of the encapsulating material and forms an amalgamation therewith without a distinct interface between the terminal board and the encapsulating material which thereby provides a fluid-tight seal around the terminal assembly. The individual terminals have an intermediate shoulder disposed adjacent the top surface of the terminal board to prevent the molding material from covering the terminal assembly during the injection molding operation and, further, to provide a sealing surface for the molding material around the terminal assembly. A shorting bar is rotatably mounted between the terminals and rotates between a closed position shorting the terminals and an open non-shorting position. A terminal cover interlocks with the shorting bar to prevent improper positioning of the shorting bar.
