Electronic card connector having improved assembly

An electrical connector comprising:

• a dielectric housing including a bottom wall, a through opening defined in the bottom wall;
• a discrete contact module having a dielectric base retaining a plurality of contacts thereto and embedded within said through opening with said contacts exposed to an exterior for mounting to a printed circuit board under the housing;
• a conductive shell attached to a top surface of the housing and cooperating with the housing to define a receiving space there between;
• and
• a tray moveably received in said receiving space and defining therein a receiving channel open to said contact module for receiving an IC card to mechanically and electrically connect to said contact module;
• wherein deformation of the housing will not integrally influence the contact module;
• wherein the dielectric housing is not integrally formed with the dielectric base while being supportably engaged therewith;
• wherein a pair of holding steps protruding inwardly from two opposite sides of the opening;
• and
• wherein a pair of eaves protruding laterally from two opposite sides of the base,
• wherein the two eaves respectively supported on the pair of holding steps and the base falling into the opening.
