Why sometimes usb cables(or other cables) have to be put in unusual position for them to work?

Question

If you can try to ELI7;

You know, an usb cable works perfectly then, the next day you have to play with it, put the cord upwards, put the cord downwards, now it works only at a specific 63 degrees angle.

I associate this with the copper wearing out, or burning… but is that really it?

They’re really small, really intricate plugs. Normally, there are several different terminals on the inside of the plug. There are a lot of points of possible failure. I’m no usb engineer, but I suspect that where the wire terminates into the usb head is a point of failure, or the usb head itself bends to the point that it no longer produces a good contact with the port, so you have to tweak it to make good contact. Try to be easier on the connection to improve the life of your cables.
