Definitions

  • the utility model relates to a power plug, in particular to a plug with an LED indicator light.
  • the usual power plug generally does not have the function of power-on indication.
  • people can't judge whether the plug is energized or in good contact with the plug itself. It can only be judged by electric pen or connected electrical appliance. The inconvenience caused.
  • people when the plug is pulled in a dim environment, people cannot clearly perceive the position of the plug, and it is necessary to touch the hand and then remove the plug, which has great safety hazards.
  • the purpose of the product of the present invention is to overcome the above-mentioned deficiencies of the existing products and to provide a plug with an LED indicator.
  • the technical solution adopted by the utility model is: providing a plug with an LED indicator, comprising a plug housing, a neutral wire insert, a firewire insert, a neutral wire inserting line in the plug housing and An LED indicator is connected between the live line inserts.
  • the LED indicator has a current limiting resistor in series.
  • the LED indicator is embedded in a lamp hole that passes through the outer surface of the plug housing.
  • the plug adopting the above technical solution, with the LED indicator light, the LED indicator is bright when the plug is inserted into the socket, and the plug can be clearly shown that the plug is energized, and in the dim environment, people can accurately distinguish the plug by the bright LED indicator. Position, safely unplug the plug.
