This invention can either be built into sources of direct current, or can modify existing sources of direct current to provide a quick-connect and disconnect single point direct current connector that prevents reverse polarity from occurring. This is in the form of a receptacle connected to positive and negative terminals with positive and negative openings into which positive and negative prongs of a plug can be inserted. The other end of the plug cable can be permanently or removably connected to jumper cable clips, to another male plug, or directly to the equipment that is driven by the direct current.

[ What is claimed is:] [1.] A jumper cable adapter for providing an auxiliary direct current to a storage battery having a projecting cylindrical positive terminal post and a projecting cylindrical negative terminal post laterally spaced a fixed distance from said positive terminal, said adapter comprising: a receptacle member having a first terminal slot and a second terminal slot, said terminal slots having non-complementary configurations, said first terminal slot adapted to telescopically receive a complementary shaped positive electrical connector connected to a positive pole of an auxiliary source of direct current, said second terminal slot adapted to telescopically receive a complementary shaped negative electrical connector connected to a negative pole of the auxiliary source of direct current; a positive bridge conductor member having a first end connected to said adapter member and operatively engagable with said positive conductor member and a second end having a cylindrical aperture therein for accommodating physical and electrical connection with said positive terminal post of said storage battery; a negative bridge connector member having a first end connected to said adapter member and operatively engagable with said negative conductor member and a second end having a cylindrical aperture therein for accommodating physical and electrical connection with said negative terminal of said storage battery, said second end of said positive bridge connector member and said second end of said positive bridge connector member having a spacing therebetween at least equal to said fixed distance between said positive terminal post and said negative terminal post of said storage battery whereby direct current may be alternatively routed to said terminal posts of said storage battery from said auxiliary source by one-way insertion of said electrical connector members into said terminal slots of said receptacle member.
