ABSTRACT:
An electrical receptacle having front and rear casings forming an enclosed housing for a printed circuit board carrying contacts into which the blades of a plug connected to the receptacle are inserted. The housing includes portions cooperatively placed with respect to the circuit board to provide underlying support for the contacts, as well as to assist in positioning the circuit board relative to the housing. The circuit components carried by the circuit board include three varistor devices for suppressing high transient voltages and the housing includes internal walls providing spaced cavities to receive the respective varistor devices. Another aspect concerns a one-piece mounting strap positioned entirely exteriorly of the receptacle housing and connected thereto by cooperative engagement portions on the strap and the housing, requiring no screws, rivets or other fastening devices.
