BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a structural diagram of a SIM card compatible apparatus in accordance with the present embodiment;
FIG. 2 is a schematic diagram of the connection of signal lines of the card slot in the SIM card compatible apparatus in accordance with the present embodiment.



PREFERRED EMBODIMENTS OF THE DOCUMENT
The present embodiment provides a SIM card compatible apparatus, which is provided with two separate card slots, and a stopper is used to make sure there is only one SIM card inserted into the card slot at the same time.
The SIM card compatible apparatus in accordance with the present embodiment comprises a first card slot for a first SIM card to be inserted into, and a second card slot for a second SIM card to be inserted into, the first SIM card is an ordinary SIM card and the second SIM card is a Micro SIM card. The first card slot and the second card slot are provided on the same base as a whole. The signal lines on the two card slots are connected together, and a stopper is provided between the two card slots, and only one SIM card is allowed to be inserted into at the same time.
For ease of understanding, in conjunction with the accompanying drawings, the embodiments of the present document will be described in detail in the following.
As shown in FIG. 1, the SIM card compatible apparatus in accordance with the present embodiment comprises: base 100, card slots for two kinds of different SIM cards: the first card slot 101 and the second card slot 102, which can be compatible with two kinds of SIM cards, the first card slot 101 is a card slot for the SIM card to be inserted into, and the second card slot 102 is a card slot for the Micro SIM card to be inserted into, and both of them are provided on the base 100.
Because it is compatible with the SIM card and the Micro SIM card, rather than using the two kinds of SIM cards simultaneously, the signal lines of the first card slot 101 and the second card slot 102 are connected together, if the user mistakenly inserts two SIM cards, it will result in an electrical fault. Therefore a stopper 103 used for preventing wrong insertion is arranged between the first card slot 101 and the second card slot 102, and can be against the bottom of the card after the card is inserted into the card slot, and the leverage principle is used to ensure that the user does not simultaneously insert two cards, thereby avoiding failure.
The stopper 103 comprises a fixed shaft 104, first blocking portion 105 and second blocking portion 106. The fixed shaft 104 is fixed to the base 100. The first blocking portion 105 and the second blocking portion 106 are connected with each other and rotatablely connected to the fixed the shaft 104, each of them corresponds to a card slot, the first blocking portion 105 extends to the inlet of the first card slot 101, the second blocking portion 106 extends to the inlet of the second card slot 102. When being inserted into by a card, the first card slot 101 corresponding to the first blocking portion 105 rotates around the fixed axis 104 under the impetus of the card and extends with the card into the first card slot 101, meanwhile the second blocking portion 106 rotates around the fixed axis 104 in an opposite direction of the first blocking portion 105, and extends to the position of the inlet of the corresponding second slot 102 to block the insertion of the card.
Similarly, when being inserted into by a card, the second slot 102 corresponding to the second blocking portion 106 rotates around the fixed shaft 104 under the impetus of the card and extends into the card slot with the card, meanwhile, the first blocking portion 105 rotates around the fixed shaft 104 in the opposite direction of the second blocking portion 106, and extends into the position of the inlet of the corresponding first slot 101 to block the insertion of the card. Even if the user violently inserts a card, the other card will be ejected, therefore the leverage principle is used to avoid the situation in which two cards are inserted simultaneously. When the user needs to change the card, the stopper can also help the user eject the existing card.
Moreover, the stopper 103 can also use the shaft, the first blocking portion 105 and the second blocking portion 106, the shaft is rotatablely provided on the base 100, the first blocking portion 105 and the second blocking portion 106 are connected with each other, and both of them are fixedly connected with the shaft.
As shown in FIG. 2, all the signal lines of the first card slot 101 and the second card slot 102 correspond with each other and are connected together. Inserting a card in any card slot can work normally, but not inserting two cards at the same time, otherwise, it will results in an electrical fault.
The present embodiment further provides a terminal device, comprising: a motherboard and a subscriber identity module card compatible apparatus, the subscriber identity module card compatible apparatus is arranged on the motherboard and comprises a base, a first card slot for a first SIM card to be inserted into, a second card slot for the second SIM card to be inserted into, and a stopper used for preventing the second SIM card from being inserted into the second card slot after the first SIM card is inserted into the first card slot, as well as preventing the first SIM card from being inserted into the first card slot after the second SIM card is inserted into the second slot, all of the first card slot, the second card slot, and the stopper are arranged on the base, and the stopper is arranged between the first card slot and the second card slot.
The stopper comprises a fixed shaft, a first blocking portion and a second blocking portion, the fixed shaft is fixed to the base, the first blocking portion and the second blocking portion are connected with each other, and both of them can be rotatablely connected to the fixed shaft, the first blocking portion extends to the inlet of the first card slot, and the second blocking portion extends into the inlet of the second card slot; or
the stopper comprises a shaft, a first blocking portion and a second blocking portion, the shaft is rotatablely fixed to the base, the first blocking portion and the second blocking portion are connected with each other, and both of them can be fixedly connected to the shaft, the first blocking portion extends to the inlet of the first card slot, and the second blocking portion extends into the inlet of the second card slot.
Signal lines are provided on both the first card slot and the second card slot, and the same signal lines of the first card slot and the second card slot are connected correspondingly with each other. The first card slot is a card slot for SIM card, and the second card slot is a card slot for Micro-SIM card.
