Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned deficiency, but proposes a kind of attaching plug that can detect the self check whether attaching plug normally be connected with power supply.
The utility model is realized with the following method.
But the attaching plug of self check has the plug body of insulating material, plant two electric mortiser utmost points of copper on the plug body, one is the live wire electric mortiser utmost point, another is the zero line electric mortiser utmost point, the electric mortiser utmost point stretches out from plug body, indicating circuit is arranged in the plug body, indicating circuit is composed in series by two dropping resistors and two middle neon bulbs at two ends, indicating circuit is connected in parallel between the live wire electric mortiser utmost point and the zero line electric mortiser utmost point, the dropping resistor at indicating circuit two ends extremely links to each other with the zero line electric mortiser with the live wire electric mortiser utmost point respectively, two neon bulbs are respectively near the live wire electric mortiser utmost point and the zero line electric mortiser utmost point, be connected with test electrode on the line between two middle neon bulbs, on the plug body, by two neon bulbs and test electrode side has indicator light window and test electrode hole respectively, and test electrode stretches out from the test electrode hole.Electric mortiser extremely can be connected with power line, and the tie point that is connected with the electric mortiser utmost point of power line and power line is in plug body.
During use, the utility model that is connected with electrical appliance is inserted in supply socket.When the live wire electric mortiser utmost point and the zero line electric mortiser utmost point are connected with the live wire of power supply and zero line respectively, two neon bulbs are all luminous, the utility model can normally be powered to electrical appliance, this moment is when touching test electrode with hand, luminous neon bulb brightness near the live wire electric mortiser utmost point strengthens, near the luminous neon bulb brightness deterioration of the zero line electric mortiser utmost point, what indicate that electric mortiser utmost point company is live wire, and what that electric mortiser utmost point connected is zero line; When the live wire electric mortiser utmost point is connected with the live wire of power supply and the zero line electric mortiser utmost point when not being connected with the zero line of power supply, two neon bulbs are not luminous, and this moment, two neon bulbs were all luminous when touching test electrode with hand; When the live wire electric mortiser utmost point and the zero line electric mortiser utmost point did not all have to be connected with power supply, two neon bulbs were not luminous, and this moment, two neon bulbs were not luminous yet when touching test electrode with hand.
The utlity model has self-monitoring function.Whether attaching plug can detect and normally be communicated with power supply; When attaching plug normally was communicated with power supply, what which electric mortiser utmost point connected was live wire, and what which electric mortiser utmost point connected is zero line; Only be communicated with the electriferous state that can detect electrical appliance when not being communicated with at attaching plug, bring convenience and allow user's electriferous state of the present utility model that can judge rightly to the user with zero line with live wire.
Below in conjunction with accompanying drawing, the utility model is further described.
