Hazardous processing

I had bought this favorable female to supplement my motorhome and experienced in recent vacation quite a disappointment.
The female seems processed fairly solid - but once it is used a little warmer or a plug vigorously, it loses its stability!
The bottom of the socket where the positive pole is attached has come loose, which is not as dramatic ansich if one expects, and (as described in another review) this fixed with adhesive tape.
Unfortunately, I have to make this discovery, when it came to strong leakage inside the bush - no pure short-circuit because in this case the fuse would have triggered. Here, Jack and the high quality connectors have heated up so much that the plastic is melted!

The now high cost of replacing the plug and socket I consider dues.
But the fire hazard posed by such an effect is considerably!

Conclusion:
Sometimes dangerous!
Hands off!
