| 161 | Do-it-yourself GFI outlet kit | US10945501 | 2004-09-20 | US07038561B2 | 2006-05-02 | Robert Esty |
| A do-it-yourself, handy man kit for modifying a home duplex ground fault interrupter unit for insertion into a home duplex wall outlet electrical system. The kit includes an open top plastic housing, a set of blades and a ground prong, and two connecting mounting screws for securing together the modified ground fault interrupter unit and the home duplex wall outlet. A set of apertures in the housing bottom wall receive the blades and ground prong mounted on the ground fault interrupter unit for insertion into the wall outlet. The two connecting mounting screws are mountably projected through external indented channels on end walls of the housing secured to aligned tabs of the ground fault interrupter unit and the wall outlet. The kit overcomes the deficiencies experienced with prior systems in securing the ground fault interrupter to the duplex wall outlet. | ||||||
| 162 | Ground fault circuit interrupter with functionality for reset | US09876156 | 2001-06-08 | US06829124B2 | 2004-12-07 | Howard S. Leopold; Gunter A. Gallas |
| A fault circuit interrupter with functionality for reset can include a relay that trips a first circuit when a ground fault or other error is detected in the first circuit. The relay can be a bistable type of relay that is caused to change state by the detection of a ground fault (or other error) in the first circuit. To reset the fault circuit interrupter after it has tripped, a reset mechanism can include means for simulating a ground fault (or other error). A signal can be sent to the relay when a simulated ground fault (or other simulated fault) is output, such that the signal causes the relay to change state to re-close the first circuit after the trip. Accordingly, the interrupter is automatically tested for functionality when it is reset. Moreover, the fault circuit interrupter cannot be reset if the circuitry of the fault circuit interrupter is not operational. | ||||||

| The present invention teaches a new and novel system for protecting people and property against electrical shock. The invention includes a number of preferred and other embodiments which have this as their goal, but which represent a number of distinctive and novel approaches to solving prior art problems. By way of example only, and without limiting the scope of this invention, these approaches include novel immersion detecting circuits, broken wire test circuits, electromechanical circuit breaking including coil/plunger arrangements, and relay circuit breaking mechanisms cooperative with associated circuitry, all of which are able to be incorporated as a system wholly within the load (appliance) and its associated cord set (including a "plug"). | ||||||
| 167 | Ground fault circuit interrupter plug | US446312 | 1995-05-22 | US5661623A | 1997-08-26 | Thomas M. McDonald; Ward E. Strang; Carol Z. Howard |
| A ground fault circuit interrupter (GFCI) line cord plug utilizes an electronically latched relay, rather than a circuit breaker or other type of mechanical latching device, to interrupt the AC load power when a ground fault condition occurs. In order to reduce the size of the relay and minimize the cost and complexity of the GFCI plug, the fixed and movable relay contact structures are mounted directly to the circuit board which carries the remaining components of the GFCI circuit. In a preferred embodiment, the fixed relay contact structures are integral with the plug blades of the GFCI plug. The movable relay contact structures preferably comprise deflectable spring arms which are preloaded when the relay contacts are in the open position in order to control the contact gap, and which are deflected past the point of contact closure when the relay contacts are in the closed position in order to increase the closing force. The principal electrical components of the GFCI plug, including the relay contacts, relay coil and sensing transformer, are mounted on the circuit board in a generally tandem or in-line arrangement in order to minimize the dimensions of the plug. | ||||||

The first flange has a parallel outer and inner wall defining a channel therebetween. The inner wall has a slot therethrough. The slot is open at one end to the top surface of the first flange and extends downward to the core. The slot is positioned on the top surface of the first flange opposite the lead pin. The channel extends from the lead pin across to the end of the slot near the core. The width of the channel and the slot are adapted for guiding a winding wire therethrough. | ||||||
| 170 | Trip-reset mechanism for GFCI receptacle | US932524 | 1992-08-20 | US5223810A | 1993-06-29 | Christopher A. Van Haaren |
| To minimize the tripping force required to trip a GFCI receptacle, a cantilever spring, formed as an integral feature of the molded plastic receptacle case, is charged in the process of resetting a trip/reset mechanism from a tripped condition and thus is empowered to provide a spring force for setting a latch releaseably holding the mechanism in a reset condition and for returning a trip solenoid plunger from its trip-initiating extended position to a return position. While the mechanism is reset, the cantilever spring is clear of the tripping motions of the latch and plunger. | ||||||
| 171 | Resettable ground fault circuit interrupter | US327012 | 1989-03-22 | US4893101A | 1990-01-09 | James M. Robitaille |
| A resettable circuit interrupter in a ground fault detector circuit utilizes a housing which slideably retains a solenoid coil wound on a bobbin. A contact carrier is attached to the bobbin and one or more moveable contacts are provided on the carrier opposite a corresponding set of fixed contacts. A plunger slides through a central passageway in the solenoid coil. The bobbin is spring biased so that the contacts are in a normally open position. In a manually resettable version, when the solenoid coil conducts a predetermined current, manually activating the plunger causes the plunger to magnetically couple to a footplate attached to the bobbin. When a plunger spring returns the plunger to its original position, the bobbin and contact carrier move with it and the contacts are closed. When the solenoid coil conducts insufficient current to magnetically couple the plunger and footplate, the bias springs maintain the contacts in the normally open position. In an electrically resettable version the contacts may be reset by electromagnetic energy alone, without manual activation of the plunger. | ||||||
| 172 | Plug-in ground fault circuit interrupter module | US539154 | 1983-10-05 | US4567544A | 1986-01-28 | DeHertburn N. Ronemus; Victor M. Tice |
| Ground fault circuit interrupter components, including a fault-sensing circuit and a relay, are enclosed within a housing having terminals for connection of the wires of a line cord extending from an electrical appliance or other electrical load for which ground fault protection is provided. Standard plug blades extend from the housing for insertion into a conventional electrical receptacle to connect the load to a source of electrical power, the circuit interrupter components being interposed between the wire connection terminals and the blades. The housing configuration and assembly provides an essentially waterproof enclosure for all elements between the line cord and plug blades which is preferably divided into two discrete compartments, one containing the wire connection terminals and the other the GFCI components. Thus, if the one compartment should develop a leak, the water-tight integrity of the other is still maintained. The line cord extends into the module through a resilient sealing grommet which may conveniently be interchanged with different size grommets to accommodate line cords of various diameters without changing any other components of the module. Assembly is simplified and facilitated by providing a one-piece body member, open at both ends, and connecting all other components as a single assembly for insertion into the body and fastening with screws at each end to sealably close the body openings. | ||||||
