Abstract:
1. A polarity-correctly-connectable intelligent receptacle adaptor, comprising an insert-to-connect device body, the insert-to-connect device body comprising at least one grounding terminal serving as E pole, at least one transmission terminal arranged at the left side of the grounding terminal, and at least one conduction terminal arranged at the right side of the grounding terminal wherein when the intelligent receptacle adaptor is connected to a power source having a voltage level of 250V, the transmission terminal is N pole and the conduction terminal is L pole, which is an arrangement of N pole at left and L pole at right; and when the intelligent receptacle adaptor is connected to a power source having a voltage level of 125V, the transmission terminal is L pole and the conduction terminal is N pole, which is an arrangement of L pole at left and N pole at right; and wherein the grounding terminal is electrically connected with at least one grounding bulb; the transmission terminal is electrically connected with at least one transmission bulb; the conduction terminal is electrically connected with at least one conduction bulb; and the conduction terminal is electrically connected with at least one conduction touch-plate, whereby when the intelligent receptacle adaptor is connected to a power source, whether the polarities are correctly set and positioned can be determined according to if the grounding bulb is lit up, or alternatively, whether the polarities are correctly set and connected can be determined according to if the conduction bulb is lit up after the conduction touch-plate has been touched; and wherein the insert-to-connect device body further comprises at least one universal surface panel for receiving the insertion of standard plugs of different countries so that the standard plugs are electrically connectable with the grounding terminal, the transmission terminal, or the conduction terminal.
