prefixconnector is the separator between the section number (=prefix) 
and the float number (=figure number), the symbol at the end of the 
float number is called numberstopper. In your example you don’t have a 
section which can act as prefix number no did you change which prefixes 
should be shown (by default only chapters are used as prefix).

The suffix key you use (together with suffixconnector and suffixstopper) 
is used to show the number for subfigures, e.g. figure 3.a.
