ABSTRACT:
An electrical plug, of male or female construction, provided with a relatively enlarged opening between the main conductors of the plug such as outwardly projecting prongs or inwardly disposed blades, for removal from and insertion therein of an overcurrent-protection device and cooperating safety latch means. The direction in which said device and latch means are removed from the plug is the same as the direction in which the plug is engaged to its mating electrical device so that such removal and replacement may be effected only if the plug or socket is not in union with its mating electrical device. The safety latch means and the associated overcurrent-protection device or component are so cooperatively constructed that when disposed within said plug body a compressive, deforming force is exerted upon said overcurrent-protection device so as to assure of proper circuit-establishing relationship of the various terminals and contacts within the plug to the prongs or blades thereby bringing about conductive relationship of a reliability heretofore unknown. The plug of the present invention is easily operated and safe, being specially designed for unskilled individuals while constituting an advantageous electrical connection between it and its associated mating device.
