Abstract
An electrical connector inlet assembly with a break-away mechanism coupled to an electric vehicle for receiving electrical energy. The break-away mechanism disconnects the contacts of the inlet assembly or receptacle from the contacts of the plug to prevent damage of the electrical connector assembly, upon application of a highly excessive force pulling the plug away from the receptacle prior to disengagement of the contacts. The electrical connector inlet assembly receives an electrical connector or plug with electrical contacts for mating with the electrical contacts of the electrical inlet assembly or receptacle. The plug has a cover for selectively covering and uncovering its electrical contacts to prevent inadvertent contact with the electrical contacts and to protect the electrical contacts from the environment. Likewise, the receptacle has a cover for selectively covering and uncovering its electrical contacts to prevent inadvertent contact with the electrical contacts and to protect the electrical contacts from the environment. In the preferred embodiment, the covers of the plug and receptacle are either automatically or manually uncovered only after full insertion of the plug into the receptacle. The plug can be inserted into the receptacle with little or no force by the user since the contacts of the plug and receptacle are not electrically coupled together until after full insertion of the plug into the receptacle.
