I'm trying to replace the cable that connects the magic wand in a VTech Magic Wand toy laptop. It's an interesting beast. Inside its outer insulator is a bunch of strands of string plus the two conductors. Each of the two conductors is a braided bundle of enameled wires around a string core.
It's clear to me that this was designed this way so that it wouldn't break under tension or repeated flexing as a kid uses the magic wand to point-to-select things on the toy's LCD screen.
But what do you call such a bundle? I'd like to replace it with something similar to the original cable, but I'm having trouble naming the product that I'm searching for.
