Abstract

A power receptacle assembly includes a plurality of AC snap receptacles each having a base containing three insulation displacement connectors and each electrically connected to a female receptacle connector element. A snap-on retainer forces three insulated power conductors into the three insulation displacement connectors causing knife blade edges thereof to displace insulation and electrically connect inner conductor elements of the insulated power conductors. The snap-on retainer of one of the AC snap receptacles also receives three slotted male tab friction fit connectors to electrically connect them to the three power conductors, respectively. The three slotted male tab friction fit connectors are connected to a printed circuit board that interacts with the three power conductors. Each slotted male tab friction fit connector has an elongated slot separating two bifurcated prongs, outer edges of the prongs frictionally engaging inner surfaces of the insulation displacement connectors. Each insulated power conductors extends through one of the elongated slots.

Claims

1. A power receptacle assembly comprising in combination:

(a) an AC snap receptacle including a base containing three insulation displacement connectors each electrically connected to a separate female receptacle connector element and each having a knife edge slot, the AC snap receptacle also including a snap-on retainer, the snap-on retainer having three connector-receiving slots;

(b) three insulated wires, each having an inner power conductor, pressed by the snap-on retainer into the three knife edge slots, respectively, causing knife edges of the knife edge slots to displace insulation of the three insulated wires and electrically contact the three power conductors, respectively; and

(c) three slotted male tab friction fit connectors connected to a circuit that interacts with the three power conductors, each slotted male tab friction fit connector having an elongated slot separating two bifurcated prongs, outer edges of each pair of prongs frictionally engaging a pair of inner contact surfaces of a separate insulation displacement/connector, respectively, the three insulated wires extending through the elongated slots, respectively.

2. The power receptacle assembly of claim 1 including a plurality of the AC snap receptacles, the three insulated wires extending into each of the AC snap receptacles and electrically contacting the three insulation displacement connectors of each AC snap receptacle, the power receptacle assembly further including a printed circuit board carrying the circuit, the three slotted male tab friction fit connectors being rigidly soldered to corresponding strip conductors on the printed circuit board.

3. The power receptacle assembly of claim 2 wherein the circuit includes a transient surge suppressor circuit that suppresses externally induced AC power line transient voltages between the power conductors.

4. The power receptacle assembly of claim 1 wherein the circuit includes a control circuit controlling flow of power to the AC snap receptacle.

5. The power receptacle assembly of claim 2 wherein the circuit includes a noise suppression circuit that suppresses noise generated on the power conductors by a utilization device plugged into an AC snap receptacle of the power receptacle assembly.

6. The power receptacle assembly of claim 3 wherein the transient surge suppressor circuit includes capacitors, inductors, metal oxide varistors, and surge suppressor semiconductor devices interconnected to form the surge suppression circuit.

7. The power receptacle assembly of claim 6 further including a power on/off switch connecting the three power conductors to a power cord and also includes a circuit breaker coupled in series with one of the power conductors.

8. The power receptacle assembly of claim 7 wherein the plurality of AC snap receptacles are mounted on a panel and the on/off switch is mounted on the panel and a housing enclosing the printed circuit board and bodies of the AC snap receptacles is attached to the panel.

9. The power receptacle assembly of claim 2 wherein the three insulated wires are rigid, each including only a single rigid center conductor surrounded by soft PVC insulation material.

10. A method of making a power receptacle assembly, comprising the steps of:

(a) attaching three slotted male tab friction fit connectors to a printed circuit board having thereon a circuit that interacts with three insulated power conductors, each slotted male tab friction fit connector having a slot separating two bifurcated prongs;

(b) mechanically and electrically connecting the three power conductors to a plurality of female power receptacles by placing the power conductors on three insulation displacement connectors, respectively, of the female power receptacle and pressing them into knife edge slots of the insulation displacement connectors by means of a snap-on retainer so that knife edges of the three insulation displacement connectors displace insulation of and electrically contact the three power conductors, respectively; and

(c) mechanically and electrically connecting the printed circuit board to the three power conductors by inserting the three slotted male tab friction fit connectors into connector-receiving slots of the snap-on retainer so that outer edges of the prongs frictionally contact inner contact surfaces of the three insulation displacement connectors and the three power conductors pass through the slots of the three slotted male tab friction fit connectors.

11. A power receptacle assembly comprising in combination:

(a) a female receptacle including a base containing three insulation displacement connectors each electrically connected to a separate female receptacle connector element, and each having a knife edge slot, the female receptacle also including a snap-on retainer, the snap-on retainer having three connector-receiving slots;

(b) three insulated wires, each having an inner power conductor, pressed by the snap-on retainer into the three knife edge slots, respectively, causing knife edges of the knife edge slots to displace insulation of the three insulated wires and contact the three power conductors, respectively; and

(c) three slotted male tab friction fit connectors connected to a circuit that interacts with the three power conductors, each slotted male tab friction fit connector having an elongated slot separating two bifurcated prongs, outer edges of each pair of prongs frictionally engaging a pair of inner contact surfaces of a separate insulation displacement connector, respectively, the three insulated wires extending through the elongated slots, respectively.
