Abstract

The present invention includes an insert-to-connect device body, which receives therein a grounding terminal, a transmission terminal arranged at the left side of the grounding terminal, and a conduction terminal arranged at the right side of the grounding terminal. The grounding terminal is electrically connected with a grounding bulb. The transmission terminal is electrically connected with a transmission bulb. The conduction terminal is electrically connected with a conduction bulb. The conduction terminal is electrically connected with a conduction touch-plate. With such an arrangement, a construction operator is allowed, in installing the present invention, to follow instructions for connection with polarity correctness and to identify if the polarities are set correct according to lighting of the grounding bulb, the transmission bulb and the conduction bulb and touching of the conduction touch-plate.

Claims

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.

2. The polarity-correctly-connectable intelligent receptacle adaptor according to claim 1, wherein when the insert-to-connect device body is electrically connected with a power source first, if the grounding bulb is lit up, it is determined that pole of the power source is correctly set in position;

if the transmission bulb is lit up, it is determined that N pole of the power source is correctly set in position;

if the conduction bulb is lit up after the conduction touch-plate has been touch, it is determined that L pole of the power source is correctly set in position.

3. The polarity-correctly-connectable intelligent receptacle adaptor according to claim 1, wherein the insert-to-connect device body comprises a conduction text section that is adjacent to the conduction bulb, a transmission text section that is adjacent to the transmission bulb, and a grounding text section that is adjacent to the grounding bulb.

4. The polarity-correctly-connectable intelligent receptacle adaptor according to claim 1, wherein at least one grounding plate is arranged between the transmission terminal and the conduction terminal for grounding when a German or French style plug is inserted.

5. The polarity-correctly-connectable intelligent receptacle adaptor according to claim 1, wherein the insert-to-connect device body comprises a first transmission terminal, a second transmission terminal, a first conduction terminal, and a second conduction terminal, the first conduction terminal and the first transmission terminal being switchable with each other for common use, the second transmission terminal and the second conduction terminal being switchable with each other for common use.

6. The polarity-correctly-connectable intelligent receptacle adaptor according to claim 1, wherein the insert-to-connect device body is selectively one of a receptacle and an adaptor, the insert-to-connect device body being mountable to all sorts of equipment and instruments for polarity detection for two-wire, three-wire, or industrial multiple-wire applications.

7. The polarity-correctly-connectable intelligent receptacle adaptor according to claim 6, wherein when being an adaptor, the insert-to-connect device body is provided, on at least one side thereof, with an insertion terminal set that is in compliance with different standards of different countries, the insertion terminal set being selectively detachable from the insert-to-connect device body.

8. The polarity-correctly-connectable intelligent receptacle adaptor according to claim 1, wherein the insert-to-connect device body is provided with a first light emission element and a second light emission element and when the insert-to-connect device body is electrically connected with a power source, if the first light emission element is lit up, it is determined that the voltage level of the power source is 125V and if the first light emission element and the second light emission element are lit up simultaneously, it is determined that the voltage level of the power source is 250V.

9. The polarity-correctly-connectable intelligent receptacle adaptor according to claim 1, wherein the conduction touch-plate is arranged at the right side of the grounding terminal and the transmission terminal is electrically connected with at least one transmission touch-plate, the transmission touch-plate being arranged at the left side of the grounding terminal, whereby when the insert-to-connect device body is connected to a power source having a voltage level of 250V, touching the transmission touch-plate at the right side causes the transmission bulb to light and when the insert-to-connect device body is connected to a power source having a voltage level of 125V, touching the conduction touch-plate at the left side causes the conduction bulb to light.
