  • Publication number: 20130012054
    Abstract: The invention relates to an electric plug, in particular a charging plug for a motor vehicle, comprising a housing and a handle for holding the electric plug, wherein the housing comprises a plug-in section, a cable connection opening and a cable conduit, the plug-in section comprises a plurality of electric contacts for plugging into a socket with contacts. A cable can be routed in the cable conduit from the cable connection opening to the plug-in section and can be electrically contacted there to the electric contacts. The cable connection opening may be arranged in a region between the plug-in section and the end of the gripping section which is remote from the plug-in section. In this way, the electric plug that is provided is such that heating of the handle can be avoided and the electric plug can also be used well and ergonomically by smaller individuals.
