Those 'buckled' connectors on sensor shield v5

JohnHoward:
I finally tracked down 'dupont 2.54 pitch connectors' as being what mate with the header strips. I can get them by the 100's from China on eBay.

It shouldn't have taken much tracking down - those are standard 0.1" pitch headers, available all over the place.

JohnHoward:
Now I've discovered the Sensor Shield and it has some different connectors. Seems these are called 'buckled' connectors. It's fine they include several patch cables with connectors but I really want to find a source of JUST the connectors, like I was able to do for the 'unbuckled' dupont connectors.

So far I have come up empty. All I have found is one place that sells the board-mount female half. What are these called and do you know of a good bulk source for just the male connector shells?

Sorry, I don't have a sensor shield and I don't know what the connectors are like.
