  The effect of an insulating barrier located at a distance $a$ from a NS
quantum point contact is analyzed in this work. The Bogoliubov de Gennes
equations are solved for NINS junctions (S: anysotropic superconductor, I:
insulator and N: normal metal), where the NIN region is a quantum wire. For $%
a\neq0$, bound states and resonances in the differential conductance are
predicted. These resonances depend on the symmetry of the pair potential, the
strength of the insulating barrier and $a $. Our results show that in a NINS
quantum point contact the number of resonances vary with the symmetry of the
order parameter. This is to be contrasted with the results for the NINS
junction, in which only the position of the resonances changes with the
symmetry.
