I took apart my 3t and accidentally cut something

Hey, so i've had my 3t for a while. in fact, I got it during the midnight black sale, so the phone means a lot to me. recently I went to Colorado and hiked Pikes Peak. my phone fell out of my pocket and when I picked it up everything still worked on it besides the screens digitizer. I went home a few days later and ordered a replacement screen from a shady website and it showed up ( about a month later ). so I was preforming the operation to recover my phone until I reached the battery. I was scared to bend my battery in half so i took some tweezers and removed the adhesive from under the battery, little did i know that i had cut a small strip/cable that went underneath the charger port.

So my question is: can someone please point to a store that i can buy all the little strips and cable that are located inside my device?

i don't know the name of the cable so I'm willing to buy all that i suspect that i need.
