Abstract

The present invention relates to a shock-proof electrical output device, which comprises a power outlet having a positive and a negative terminal, a voltage converter with a high voltage input and a low voltage output, a current monitoring relay device, a latching relay device, and a changeover relay device.

Claims

1. An electrical output device comprising:

an outlet having a positive and a negative terminal;

a voltage converter with a high voltage input having a positive and a negative terminal; and

a low voltage output having a positive and a negative terminal;

a current monitoring relay device comprising a switch, a first contact, and a common contact, wherein the common contact is in communication with the positive terminal of the voltage converter;

a latching relay device comprising a trigger button, a reset button, a first contact, a second contact, and a common contact, wherein the common contact is in communication with the positive terminal of the low voltage output of the voltage converter; and

a changeover relay device comprising a switch, a first set, a second set, and a third set of switch contacts, each set having a first contact, a second contact, and a common contact;

wherein the first contact of the first set of the changeover relay device is in communication with the trigger button, the second contact is in communication with the positive terminal of a high voltage power line, and the common contact is in communication with the negative terminal of the outlet;

wherein the second contact of the second set of the changeover relay is in communication with the first contact of the current monitoring relay device and the common contact is in communication with the reset button of the latching relay device;

wherein the first contact of the third set of the changeover relay is in communication with the negative terminal of the high voltage power line and the common contact is in communication with the positive terminal of the low voltage output; and

wherein the switch of the changeover relay device is in communication with the second contact of the latching relay device.

2. The electrical output device of claim 1 further comprising a current overload protection circuit.

4. The electrical output device of claim 2 further comprising a current overload protection circuit.

3. An electrical output device comprising:

an outlet having a positive and negative terminal;

a voltage converter with a high voltage input having a positive and negative terminal; and

a low voltage output having a positive and negative terminal;

a current monitoring relay device comprising an inlet and outlet, wherein the inlet is in communication with the positive terminal of the outlet;

a latching relay device comprising a trigger button, a reset button, a first contact, a second contact, and a common contact, wherein the common contact is in communication with the positive terminal of the low voltage output of the voltage converter; and

a changeover relay device comprising a switch, a first set, a second set, and a third set of switch contacts, each set having a first contact, a second contact, and a common contact;

wherein the first contact of the first set of the changeover relay device is in communication with the trigger button, the second contact is in communication with the positive terminal of a high voltage power line, and the common contact is in communication with the negative terminal of the outlet;

wherein the second contact of the second set of the changeover relay is in communication with the outlet of the current monitoring relay device and the common contact is in communication with the reset button of the latching relay device;

wherein the first contact of the third set of the changeover relay is in communication with the negative terminal of the high voltage power line and the common contact is in communication with the positive terminal of the low voltage output; and

wherein the switch of the changeover relay device is in communication with the second contact of the latching relay device.
