Definitions

  • the present invention relates to a waterproof power coupler.
  • Electrical leads terminate at one end with a male plug portion that can be connected to a power point.
  • the power point is part of a power board or the like.
  • a second end of the electrical lead is generally engaged with an appliance, tool, some piece of an electrical apparatus or the like, to which electrical power is to be supplied.
  • the male plug portion of the electrical lead and the power point are frequently exposed to the environment. This is of particular concern where an electrical lead is being employed in a wet area and the power point is exposed to hazards such as water, dust and/or particulate intrusion. For example, on a building site, construction site, mine or the like. Similar issues can occur around the backyards of the general public.
  • a further problem in respect of the abovementioned power boards is that the male plug portion and power outlet can become disconnected, resulting in a loss of electrical power to the appliance, tool or other electrical apparatus.
  • the exposure of a male portion that is half plugged in can also leave a dangerous live circuit exposed which could cause a fire or electrocution.
  • the cover does not seal the board while the male plug portion is inserted into the power point. That is, during operation there is no waterproof seal.
