Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 154 words
A plug for extracting electrical energy from a cigarette lighter receptacle of a motor vehicle and for delivering electrical current at a voltage different from that available from the lighter receptacle, said plug comprising: (a) a cylindrical body sized to fit snugly within the receptacle; (b) a printed circuit board disposed within said cylindrical body; (c) electronic components mounted on said printed circuit board within said cylindrical body for shifting the voltage of electrical current flowing therethrough; (d) at least one of the electronic components on said printed circuit board generating heat within said cylindrical body when electrical current is flowing therethrough; and (e) a spring connector mounted on said printed circuit board within said cylindrical body and having a portion thereof extending externally of the cylindrical body for engagement with the receptacle, said connector extending in close proximity to said one electronic component for carrying heat away from said component to said receptacle.
Claim 2
Dependent Claim 154 words
A plug for extracting electrical energy from a cigarette lighter receptacle of a motor vehicle and for delivering electrical current at a voltage different from that available from the lighter receptacle, said plug comprising: (a) a cylindrical body sized to fit snugly within the receptacle; (b) a printed circuit board disposed within said cylindrical body; (c) electronic components mounted on said printed circuit board within said cylindrical body for shifting the voltage of electrical current flowing therethrough; (d) at least one of the electronic components on said printed circuit board generating heat within said cylindrical body when electrical current is flowing therethrough; and (e) a spring connector mounted on said printed circuit board within said cylindrical body and having a portion thereof extending externally of the cylindrical body for engagement with the receptacle, said connector extending in close proximity to said one electronic component for carrying heat away from said component to said receptacle.
Claim 3
Dependent Claim 60 words
The plug of claim 1, further characterized by having an opening to the interior thereof and a second electronic component disconnectably mounted on said printed circuit board in the vicinity of said opening whereby said second electronic component is accessible by and disconnectable form said printed circuit board by means of a tool inserted into the plug through said opening.
