Cord set with a breakable connector

A cord set for connecting a vehicle to a power source, the cord set comprising:

• a first cord having a first end and a second end, said first end having a first connector adapted to be selectively connected to the power source;
• a second cord having a first end and a second end, said first end having a second connector adapted to be selectively connected to the vehicle;
• and
• a coupling mechanism operable to selectively couple said first cord to said second cord, said coupling mechanism comprising:
• a first fitting fixedly attached to said second end of said first cord and including a housing having a plurality of sealing ribs extending radially outwardly from said housing, a plurality of projections extending radially outwardly from said housing, and a plurality of current-conducting pins, said plurality of projections including at least one projection having a different geometry than others of said plurality of projections;
• and
• a second fitting fixedly attached to said second end of said second cord and including a housing having a first plurality of apertures and a second plurality of apertures, said first plurality of apertures matingly receiving said plurality of projections and said second plurality of apertures matingly receiving said current-conducting pins;
• wherein said projections are adapted to engage said first plurality of apertures to connect said first fitting to said second fitting and are adapted to disconnect from said first plurality of apertures when the cord set is placed under a predetermined tensile force.

A method of interconnecting a vehicle and a power source, the method comprising:

• connecting a first end of a cord set to the power source;
• connecting a second end of said cord set to the vehicle;
• moving the vehicle away from the power source with said cord set still connected to the power source and to the vehicle;
• placing the cord set under tension due to movement of the vehicle relative to the power source;
• and
• disconnecting a breakable connector positioned between said first and second ends of said cord set when a predetermined tensile force is experienced by the cord set.
