Abstract
An electrical unit outlet device is disclosed for controlling power isolation, based on a predetermined time, for a device charger, while remaining plugged into a power outlet. A power isolating circuit cuts any power to the charging device off when charge is complete.
Claims15
An electrical outlet unit comprising:
- a. a housing;
- b. a power cord connected to said housing and having a connection on a distal end for electrical connection to a power source;
- c. a plurality of grounded electrical outlet receptacles located in said housing, each said outlet receptacle having a ground connection;
- d. a timer unit located within said housing which may be initiated from the exterior of said housing, said timer unit including a timing circuit electrically connected to each said outlet receptacle of said plurality of grounded electrical outlet receptacles;
- e. an electrical surge protector circuit in said housing and electrically connected to each said outlet receptacle of said plurality of grounded electrical outlet receptacles;
- f. a grounding circuit electrically connecting the grounding circuit of each of said grounded outlet receptacles to a grounded conductor of the power cord;
- g. an initiation switch on said housing, said initiation switch being electrically interposed between said power cord and said electrical surge protector circuit and including (1) a “non-charging” position which electrically disconnects said electrical surge protector circuit from power when said initiation switch is in a “non-charging” condition and (2) a “charging” position which electrically connects said electrical surge protector circuit to power and to said timing circuit, and,
- h. the “non-charging” position and the “charging” position of said initiation switch being mutually exclusive of each other so that when said initiation switch is in one of said positions, it cannot be in any other of said other positions.
5 more elements
An electrical outlet unit comprising:
- a. A housing;
- b. A main electrical inlet for receiving electricity from an external alternating current power source;
- i. A plurality of electrical outlets for discharging electricity wherein said main electrical inlet and said plurality of electrical outlets are mounted to said housing and are electrically connected by a plurality of cooperating circuits further comprising:
- 1. A surge protection circuit, wherein said surge protection circuit is connected to said alternating current power source;
- 2. A power supply circuit, wherein said surge protection circuit diverts current having a voltage potential above a predetermined value away from said power supply circuit;
- 3. A timer circuit, wherein said timer circuit is electrically connected to said power supply circuit;
- 4. A relay circuit, wherein said timer circuit is electrically connected to said power supply circuit and wherein at least one relay contact opens to isolate said electrical power source from said plurality of electrical outlets or said at least one relay contact closes to allow electrical power to flow from said electrical power source to said plurality of electrical outlets;
- and,
- ii. wherein said timer circuit controls the duration current is allowed to flow from said power supply circuit to said relay circuit to said plurality of said electrical outlets.
6 more elements
A method of controlling an electrical outlet unit comprising:
- a. Controlling an electrical current into an electrical circuit through an electrical surge protection circuit by an initiation switch, wherein said initiation switch is electrically interposed between said electrical current entering said electrical circuit and said electrical surge protector circuit, wherein said initiation switch includes a “non-charging” position which electrically disconnects said electrical surge protector circuit from said electrical current when said initiation switch is in a “non-charging” condition and a “charging” position which electrically connects said electrical surge protector circuit to power;
- and,
- b. Selecting the amount of time said electrical current enters said electrical circuit by connecting a timing circuit to said electrical circuit.
