The insulating housing comprises a first mounting surface and a second mounting surface parallel to each other and a tongue portion extending downwardly in an up-to-down direction. The first mounting surface is lower than the second mounting surface in the up-to-down direction forming a stepped surface. The tongue portion extends far away from the stepped surface and comprises opposite periphery surfaces. The first contact comprises a first connecting portion on the first mounting surface and a first contacting portion extending along one periphery surface of the tongue portion while the second contact comprises a second connecting portion on the second mounting surface and a second contacting portion extending along the other periphery surface of the tongue portion.
