Abstract
A universal AC adaptor has a transformer unit for converting standard AC line voltage to DC voltage and a plurality of plugs. Each plug has a flexible lead coupled to an output cord from the transformer unit at a coupler box. The leads allow the plugs to move independently of one another. Each plug also has a socket having a particular configuration which is different from the sockets of all the other plugs. Each socket is configured to mate with a particular receiving socket of a DC or an AC electrical appliance. The AC adaptor has enough plugs so as to be useable with most of the models of electrical appliance of a particular consumer electronic market, for example, video game units.
Claims10
A universal. AC adaptor for home video games, comprising:
- a transformer unit having a housing, a wall plug protruding through said housing and engageable with a standard wall outlet, a transformer having a primary winding and a secondary winding and contained within said housing and coupled to said wall plug at the primary winding thereof for stepping down the AC voltage from the wall outlet, a rectifier circuit contained in said housing and coupled to the secondary winding of said transformer for rectifying the stepped-down voltage to a DC voltage, and a variable resistor connected in parallel to the output of said rectifier circuit;
- an output cord having a first end coupled to the output of said rectifier circuit and a second end;
- and
- a plurality of at least three plugs, each said plug having a flexible lead coupled to the second end of said output cord and having a connector protruding therefrom;
- each said connectors of said plugs having a configuration different from said connectors of the other said plugs, said configuration being defined by diameter and voltage polarity;
- each said connector having a configuration which is useable with a particular home video game unit;
- and
- first and second home video game units coupled respectively to first and second plugs of said plurality of plugs;
- whereby said adaptor is useable with most home video game units in that said plurality of plugs have configurations compatible with most home video game units on the market.
A universal AC adaptor for use with a particular consumer electronic market, said adaptor being useable with most models of electrical appliance for said market, comprising:
- a wall plug engageable with a wall outlet;
- a transformer unit having a housing, a transformer contained within said housing and coupled to said wall plug at the primary winding thereof, and a rectifier circuit contained in said housing and coupled to the secondary winding of said transformer;
- an output cord having a first end coupled to the output of said rectifier circuit and a second end;
- a coupler box connected to said second end of said output cord;
- a plurality of plugs, each said plug having a flexible lead and a socket protruding therefrom, each said lead being coupled to said coupler box;
- each said socket having a different configuration from all of the other said sockets, said configuration being defined by diameter and voltage polarity;
- and
- each said socket having a configuration which is useable with a particular electronic appliance of said market.
An AC adaptor for use with one or more electronic appliances requiring approximately the same DC voltage, current, and/or power, comprising:
- a transformer unit having a housing, a wall plug engageable with a standard wall outlet, a transformer having a primary winding and a secondary winding and contained within said housing and coupled to said wall plug at the primary winding thereof for stepping down the AC voltage form the wall outlet, a rectifier circuit contained in said housing and coupled to the secondary winding of said transformer for rectifying the stepped-down voltage to a DC voltage, and a variable resistor coupled in parallel to the output of said rectifier circuit;
- an output cord having a first end coupled to the output of said rectifier circuit and a second end;
- and
- a plurality of plugs having a flexible lead coupled to the second end of said output cord and having a socket protruding therefrom, each said plug being independently movable with respect to the other said plugs;
- each said socket having a configuration different from at least one other said socket and being useable with an electronic appliance.
