Description

Technical Field

[0001] The utility model relates to the technical field of plugs, in particular to an anti-leakage plug. Background Art

[0002] The anti-leakage plug is also called the leakage protection plug. Its working principle is to insert the two power lines (live line and neutral line) of the plug into the center hole of a special "zero-sequence current transformer" at the same time. When the appliance is in normal power use, the current flowing through the live line and the neutral line is completely equal, the current goes in and out, and the secondary coil of the current transformer has no voltage output. When there is "residual current" in the "ground loop" (including the earth loop), the current of the two power lines inserted into the transformer is unbalanced, and a voltage signal proportional to the current will be generated at the output end of the "current transformer". As long as the voltage signal is large enough, this voltage signal will be processed by the integrated circuit amplification of the dedicated circuit board, and the thyristor on the trigger board will be changed from cut-off to conduction, so that the trip coil connected in series in the loop is energized, thereby disconnecting the main circuit tripping device to protect the personal safety that may come into contact with the power supply.

[0003] The prior art anti-leakage plug is usually used to power up an electric water heater in a bathroom. When the three-phase plug of the anti-leakage plug is plugged into the socket panel on the wall, water condensed from the hot water vapor in a bath is easily introduced into the connection between the anti-leakage plug and the socket panel, causing the three-phase plug of the anti-leakage plug to be prone to leakage due to moisture. For this reason, we propose an anti-leakage plug. Utility Model Content

[0004] The main purpose of the utility model is to provide an anti-leakage plug, in which a waterproof mechanism is arranged at the plug body above the leakage protection box. When the plug body is inserted into the wall socket panel, the U-shaped card plate of the waterproof mechanism can press the U-shaped rubber pad to contact the bathroom wall surface outside the socket panel to form a water-blocking structure. At this time, the waterproof mechanism can waterproof between the plug body and the bathroom wall where the socket panel is located, preventing condensed water generated by condensation of humid water vapor in the bathroom from flowing into between the plug body and the socket panel, avoiding the hidden danger of water ingress and leakage at the plug body, and can effectively solve the problems in the background technology.
