Description
Technical field
The utility model relates to a kind of mobile phone bimodulus card, and this mobile phone bimodulus card can make a mobile phone use two SIM card number simultaneously.
Background technology
Chinese patent 00212004.6 discloses a kind of two card even numbers mobile phone, comprise whole mobile phone, it is characterized in that the inner back side of mobile phone is provided with two card slots, two card slots are parallel to change over switch by circuit, change over switch is arranged on the surface of mobile phone, these product two cards can use simultaneously, not only economy but also practicality, when need not to use back and forth dismounting change card, give to use the user of two mobile phone cards to bring great convenience, help maintaining mobile phone and mobile phone card again, need not often open bonnet and dismounting mobile phone card, can prevent that again the mobile phone card from losing, how many costs are this structure need not to increase, promptly can be mobile phone and set up a plug-in card function, realize the two card of machine even numbers.But this technical scheme must be transformed mobile phone, and existing single deck tape-recorder mobile phone can't use, and makes troubles for the mobile phone manufacturer, therefore, needs to propose a kind of novel mobile phone bimodulus card.
Summary of the invention
The purpose of this utility model is to provide a kind of mobile phone bimodulus card, and this mobile phone bimodulus card can make a mobile phone use two SIM card number simultaneously, and can automatically switch between the network of two communication companies of CHINAUNICOM and China Mobile.
The purpose of this utility model is realized by following technical proposals: a kind of mobile phone bimodulus card, a SIM card installation base plate is arranged, its main points are: the one side of described installation base plate is provided with 6 and covers the copper splicing ear, this splicing ear and the interior corresponding setting in contact of the SIM card mounting groove of mobile phone, the another side of described installation base plate is provided with control circuit, comprise central processing unit in the described control circuit, SIM card 1, SIM card 2, the PB5 end of described central processing unit is electrically connected with the pin 2 of SIM card 1, the PB3 end of described central processing unit is electrically connected with the pin 2 of SIM card 2, the PB4 of described central processing unit end with cover copper splicing ear 2 and be electrically connected, the GND end of described central processing unit and the pin 3 of SIM card 1, the pin 3 of SIM card 2, cover 3 parallel connections of copper splicing ear, the VCC end of described central processing unit and the pin 4 of SIM card 1, the pin 4 of SIM card 2, cover 4 parallel connections of copper splicing ear, the pin 1 of described SIM card 1 and the pin 1 of SIM card 2, cover 1 parallel connection of copper splicing ear, the pin 5 of described SIM card 1 and the pin 5 of SIM card 2, cover 5 parallel connections of copper splicing ear, the pin 6 of described SIM card 1 and the pin 6 of SIM card 2, cover 6 parallel connections of copper splicing ear.
The utlity model has the advantage of on a mobile phone, using two SIM card number simultaneously, and can between the network of two communication companies of CHINAUNICOM and China Mobile, automatically switch, the machine of needn't tearing open changes card, only needs the switching by two SIM card of button operation control number.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
