Replacing internal battery connection

I have diagnosed the problem I am having and this website has helped a lot. My trouble now is finding the part. Once the back is taken off and the battery is removed, there are three prongs that have two pieces to each. This three prong connection appears to be removable once the next layer is taken off. I have looked all over my area for one and cannot find one. I am wondering if I can buy it online, instead of having to either buy a new 3DS or a broken one just for the piece. Thank you ahead of time for any help.
