ABSTRACT:
An electrical connector for connecting an electrical plug having prongs to circuitry has a pair of electrically conductive sockets adapted to receive the plug prongs. Each socket has an inner leg, an outer leg, and a portion which is narrower than a plug prong. An elastically deformable supporting member supports the sockets with a pair of cantilevered inner supports, which support the inner legs and define a cavity between the sockets into which the inner supports can be deflected. This allows the inner legs to deflect when the plug prongs are inserted into the sockets past the narrow portions. An intermediate member is disposed in the cavity and contacts at least one inner support at a fulcrum point at which the intermediate member opposes deflection of the inner support into the cavity, causing the corresponding inner leg to grip the plug prong with a retention force. If desired, a thermal cutoff mechanism can interrupt the electrical connection between the circuitry and one of the sockets when the intermediate member exceeds a threshold temperature, thereby disconnecting the plug.
