DUAL SIM CARD CONTACTING DEVICE FOR MOBILE PHONE

摘要

A dual SIM(Subscribe Identity Module) card-connecting device of a mobile communication terminal is provided to use SIM cards together with each other within the mobile communication terminal even without SIM card slots, thereby improving the convenience of a user. A PCB(Printed Circuit Board) is constructed so that the PCB is electrically connectable to a mobile communication terminal. A first SIM card-coupling unit(10) is connected to one side of the PCB, wherein the first SIM card-coupling unit has a plurality of catching protrusions formed of gold or silver. A lower case(20) is fixed to the PCB, wherein the lower case has a plurality of catching grooves at which the catching protrusions of the first SIM card-coupling unit are caught. A second SIM card-coupling unit(15) is connected to the other side of the PCB, wherein the second SIM card-coupling unit has a plurality of catching protrusions formed of gold or silver. An upper case(30) is joined to the lower case, wherein the upper case has a plurality of catching grooves at which the catching protrusions of the second SIM card-coupling unit are caught. A SIM card-fixing unit(40) wraps the joined lower case and upper case entirely so that the SIM card-fixing unit is joined to the upper case and the lower case and fixed to the PCB.
