1. A connector device for use in an internal combustion engine having a power source, a fuel injector, an oxygen concentration detector detecting the components of exhaust gas, and an electronic control unit calculating a basic fuel injection time period and calculating a correction value of the basic fuel injection time period on the bases of an output signal of the oxygen concentration detector for producing a control signal indicating an actual fuel injection time period of the fuel injector, said electronic control unit having a nonvolatile memory for storing the mean value of the correction value therein, and an output for outputting voltage corresponding to the correction value, said connector device comprising:

  • an output terminal connected the output of the electronic control unit and outputting the voltage corresponding to the correction value;

    a power input terminal connected to the nonvolatile memory for applying an electric power to the nonvolatile memory;

    a power supply terminal connected to the power source;

    a connector body firmly supporting said output terminal, said power input terminal and said power supply terminal;

    a cap removably fitted onto said connector body and covering said output terminal, said power input terminal, and said power supply terminal; and

    a connecting terminal firmly supported by said cap and being connectable to said power input terminal and said power supply terminal for connecting said nonvolatile memory to the power source when said cap is fitted onto said connector body.
