Connector for electric plug
First Claim
1. A connector for mounting on an electrical plug for disposition in an electrical receptacle without preventing prongs of the plug from being inserted sufficiently into the receptacle for connection to a source of power including:
- a housing of an electrically insulating material;
said housing having a receptacle therein, said housing fully enclosing said receptacle;
said housing having a relatively thin portion extending from one side thereof and away from said receptacle;
said thin portion having at least two openings extending therethrough;
a pair of electrically conductive strips mounted within said thin portion, each of said electrically conductive strips having an opening therein with each of said openings aligned with the corresponding opening in said thin portion to enable one of the prongs of the plug to pass therethrough;
said openings in said electrically conductive strips being smaller than the prongs of the plug to grasp the prongs of the plug when the prongs are inserted therein;
each of said electrically conductive strips being formed of a material capable of expanding to receive the prongs of the plug and returning substantially to its original shape after the prongs of the plug are withdrawn therefrom;
and electrical means disposed in said receptacle in said housing and connected to said electrically conductive strips to receive power therefrom when the plug is connected to a source of power through the electrical receptacle.

Abstract
A housing has two openings to receive the electrically conductive prongs of a plug to mount the housing and a third opening to receive the grounding prong. Electrically conductive strips are disposed within the housing and have the conductive prongs of the plugs, which pass through the two openings in the housing, pass through openings in the electrically conductive strips to be in contact with the strips to provide a source of power to the strips, which are electrically connected to an alarm circuit. The alarm circuit produces an audible signal whenever there is no current through the plug due to a power failure or the plug being removed from its power source and a battery, which is supported within the housing, is connected to this alarm circuit.
