Definitions

  • the present invention relates to electrical connector assembly. Particularly it relates to electrical connector assembly having electrical plug and appertaining electrical receptacle for providing power supply from power source to electrical appliance. Even more specifically it relates to the electrical plug which supports multiple current ratings like 2 A, 6A, 16A or combination thereof.
  • Power plugs There are many types of power plugs available throughout the world, many of which are designed to be used only with specific voltages and in their intended power receptacles. Power plugs are generally male while the power receptacles or sockets are female, meaning that the power plug will be inserted into the receptacle, rather than the reverse. Every power plug is designed to carry voltage safely into and out from appliances. Power plugs provide a relatively safe method for attaching appliances to an otherwise dangerous and sometimes deadly power source. The plugs are designed to complete the circuit for the desired appliance, sending power into and taking unused power out from appliances.
  • the 3 pin power plug mainly consists of three pins. Each pin of the 3 pin power plug has specific function. One pin serves as a live pin which feeds power into an electrical appliance. Second pin serves as a neutral pin which draws unused power back to the power source. The live pin and neutral pin creates a closed circuit for power to flow through.
  • the third pin serves as a ground pin or earth pin which acts as a safety device that is usually connected to the metal casing of the electrical appliance. In case of malfunctioning by the electrical appliance, the metal casing becomes electrified, the ground pin directs the voltage into a safe ground so that the appliance user is not electrocuted.
  • 3 pin socket or receptacle three openings are provided to receive three pins of the 3 pin power plug.

Abstract

La présente invention concerne un ensemble connecteur électrique unique. L'ensemble connecteur électrique comprend des fiches qui peuvent être utilisées pour de multiples courants nominaux de 2 A, 6 A et 16 A. L'invention concerne en outre des prises électriques connexes, compatibles avec les fiches de la présente invention. En raison des multiples courants nominaux, les fiches sont plus fiables et peuvent être mieux utilisées. De plus, les multiples courants nominaux permettent d'économiser du matériau, de fournir une sécurité accrue et sont rentables pour l'utilisateur.
