ES1 131 Red and Black wires and round black end part adhesive

Hi
Does anyone know what the black and red wires and the round black ending to them are as ringed in this picture of my acer ES1 131 notebook are just below the wifi adapter? (I think other models may have the same thing)

In my computer, as seen in the picture below, the sticky pad holding the round black part at the end of the wires has become detached with the sticky part left on the surace it was attached to - does this part need to be stuck down? Is it just to keep it out of the way?
If I was to replace the adhesive pad would it need to be a particular type for example heat resistant?

Thanks
