First of all, it doesn't matter if it is AC or DC; a bad connection point will generate heat when enough of either kind of current passes through.
A bad connection point means that the resistance of that point is much higher than the wire (good conductor) on either side of the bad connection.
Power equals current-squared times resistance. This is a fundamental formula used in electric calclulations. If you increase the resistance (bad connection), the power dissipation goes up (it gets hot).

One possible reason is because the connection is arcing to try to complete itself. Anytime something arcs it generates undue heat. You can compare it to a fire started in the home due to faulty A/C wiring. Different type of elecctricity, but same reason (on a much smaller scale, of course, in your situation).

because of the electrical arch formed by the 2 wires/connectors
