Why won't my cable insert all the way into my phone's charging port?

One day I just couldn't get the micro USB cord to insert itself completely into my phone's charging port, making it inpossible to charge my phone. NP I thought, I'll just purchase a universal wall charger and bypass the broken port altogether. Problem is that my phone isn't the type that one can just slide the back cover off & remove then reinsert the battery whenever they fancy. In fact by trying to do so I may have already caused irreversible damage to my phone, ugh! I jumped the gun and any remedy might already be too late. But before giving up completely, I'd like to know what the inside of the port is supposed to look like in it's uncorrupted state, ie how many pins there are supposed to be and which direction they're supposed to be facing, etc. Or can someone show me a photo or diagram of one while explaining how to bend a pin gone awry back to it's original position. This would really help me in understanding the correct way to fix it. Thanks!
