[Q] Connector, male to female

[procarion]

Ahoy!
I am looking for a way to use HDMI output AND a keyboard at the same time.
When i see it correct, the keyboard dock has an output of the same size as the tab itself. Do you know where to get or how to make a connector that will connect the female output on the keyboard with the male input of the hdmi, chargin, etc. dock?
Maybe i would have to take away the power of the hdmi dock of course...
see pics attached:

The local store told me the input on the keyboard is for charging!? Can somebody please confirm/deny this? I think that can't be true. It's the most stupid place for the main cable. The cable would always bend to a sharp angle.
