Safety jumper apparatus
First Claim
1. An apparatus for safely jumpering one vehicular battery to a second vehicular battery, comprising:
- a first receptacle connector installed in a first vehicle having positive and negative contact surfaces connected to positive and negative terminals of said one vehicular battery, respectively;
a second receptacle connector installed in a second vehicle having positive and negative contact surfaces connected to positive and negative terminals of said second vehicular battery, respectively;
a cable to connect said first and second receptacle connectors containing positive and negative conductors having a plug connector at each end of the cable, each plug connector having positive and negative contact surfaces connected to said positive and negative conductors of said cable and adapted to mate with said positive and negative contact surfaces of said first and second connector receptacles, respectively, whereby an electrical path between the batteries is completed such that the positive and negative terminals of said one vehicular battery are connected to the positive and negative terminals of said second vehicular battery, respectively, and;
said first and second receptacle connectors including switching means to prevent accidental shorting between said positive and negative contact surfaces connected to said positive and negative terminals of said vehicular batteries.

Abstract
An apparatus for safely connecting the batteries of two vehicles to jump start one of the vehicle engines. Safety is achieved by three means: 1) The location for making the connection is removed from the vicinity of the battery. The remote connector eliminates the potential for ignition of battery-generated gasses and also the potential for other accidents associated with open vehicle engine compartments. 2) The connector itself is designed so that the connection can be made in only one way, positive to positive and negative to negative, eliminating the possibility of reversing polarity and the resulting damage to personnel and to vehicles. 3) The connector is easy to use and inexpensive to manufacture because of unitized construction; positive and negative contact surfaces are included in each connector half.

5. An apparatus for safely jump starting a first vehicle with a discharged battery using a second vehicle with a charged battery, comprising:
-
a first receptacle connector installed in a first vehicle having positive and negative contact surfaces connected to positive and negative terminals of said discharged battery, respectively; a second receptable connector installed in a second vehicle having positive and negative contact surfaces connected to positive and negative terminals of said charged battery, respectively; a cable to connect said first and second receptacle connectors containing positive and negative conductors having a plug connector at each end of the cable, each plug connector having positive and negative contact surfaces connected to said positive and negative conductors of said cable and adapted to mate with said positive and negative contact surfaces of said first and second connector receptacles, respectively, whereby an electrical path between the charged and discharged batteries is completed such that the positive and negative terminals of said charged battery are connected to the positive and negative terminals of said discharged battery, respectively, and; said first and second receptacle connectors including polarity protection means to prevent accidental shorting between said positive and negative contact surfaces connected to said positive and negative terminals of said charged and discharged batteries. - View Dependent Claims (6, 7, 8, 9)
