USB-B mount to rs232/ttl

I'm kind of new to this so bear with me.

I'm looking to mount a usb type B connector to my project so that I can use a regular cable to hook up to my computer so I can upload sketches as well as get data from my Arduino Pro or Mini. However, I do not want it mounted directly to the Arduino. Something similar looking to this: http://www.amazon.com/2-5ft-female-panel-header-motherboard/dp/B00NIGFZQC but rs232/ttl.

The problem is that I can't find one, or even know if I'm using the correct search terminology.

Any help or suggestions would be greatly appreciated.

Any here?

This explains what you need

I'd think something like this one in LarryD's link would work.

I'm pretty sure I've seen these with nice weather proof seals.

If you don't find one in the list LarryD provided, let us know. I know I've seen other versions of these and I could probably find some other options.

Edit: The examples LarryD and I suggested just bring the USB lines inside. You want the connector to include a USB to TTL converter. I don't think I've ever seen one of these. You'll need to use one of the devices mikb55 linked to in order to roll your own connector.

BTW, TTL and RS232 are two different things. You want a USB to TTL.
