iPhone don't charge and don't turn on affter connected to charger

Hello, I connnected my iphone 5 to a other company charger. The cable turned hot and the pin connector from cable got like burned. After this, the iphone was useful until the battery got empty.

Once the battery was uncharged the phone won´t charge anymore. I tried with an original charger and different cables. So I look for an answer here and did buy an orignal lightning dock connector. After installing the iphone still don't charge.

I don't know if it's the battery or if you could help me to know what happend to my iphone.

Thank you in advance.
