Abstract
A dual SIM card connector for holding a first SIM card and a second SIM card and installing in a cellular phone is disclosed. The dual SIM card comprises a housing and an inter-layer. The inter-layer is inside the housing. Between the inter-layer and the housing, there forms a first slot and a second slot. The inter-layer comprises: a common recess on the first surface of the inter-layer, wherein the common recess has a through hole. A common GND contact spring leaf is mounted in the common recess and electrically coupled to both the first SIM card and the second SIM card through the through hole.
