To be honest, if you really want to have electrical schematics, I don't
think Visio is *the* application. Even if you have figured out how to do it
(in your case, you have to modify the shapes and add more 'glue' points), it
will still be a poor representation.
There are quite cheap basic electronic programs available (between 100 and
200 Euro/dollar, and some of them even for free), that will perform better
than Visio.

I have some problems using shapes of circuits and logic shapes (how can i
connect the 4 lines of a 4 line bus, just 1 line connects to other
shapes,
or how can i draw a chip or a bus with more than 4 inputs pins). were can
i
find help on the shapes. i am not an expert in electrical engineering and
just need to draw some simple logic circuits.
