The SIM card seat is used for receiving a SIM card, which comprises a housing, a signal conducting terminal, a card holder and a ejector. The signal conducting terminal is disposed on the motherboard. A receiving space is formed between an area of the motherboard where the signal conducting terminal is located and the housing, which is used for receiving the card holder and ejector. The card holder is used for receiving the SIM card and matching different types of SIM cards. The ejector is used for ejecting the card holder out of the receiving space. The mobile terminal comprises the SIM card seat. The SIM card seat according to the present disclosure can match different types of SIM cards by changing the card holder, thus the mobile terminal having the SIM card can match various SIM cards accordingly. Therefore, it is not required for the user to change the SIM card to match various mobile phones, which is convenient for the user, and reduces waste of resources. ## Claims ### Claim 1 A SIM card seat, positioned on a motherboard and for receiving a SIM card, the SIM card seat comprising a housing, a signal conducting terminal, a card holder and an ejector, wherein the signal conducting terminal is disposed on the motherboard for conducting with the SIM card; a receiving space is formed between an area of the motherboard where the signal conducting terminal is located and the housing, which is configured to receive the card holder and the ejector, the card holder is configured to receive the SIM card and match different types of SIM cards, the ejector is configured to eject the card holder out of the SIM card seat from the receiving space. ### Claim 2 (depends on 1) The SIM card seat according to claim 1, wherein the card holder comprises a first side and a second side adjacent to the first side, and the ejector comprises: a second rod positioned at the second side and rotatable in the plane of the SIM card seat; a first rod positioned at the first side and movable in a direction substantially perpendicular to the second rod to make the second rod rotate via the engagement there between; and a push pin configured to drive the first rod to move in the direction substantially perpendicular to the second rod. ### Claim 3 (depends on 2) The SIM card seat according to claim 2, wherein the ejector has switchably a normal state and a working state, wherein: in the normal state, the first rod and second rod are positioned perpendicular to each other in the receiving space, wherein an end of the first rod is positioned close to a head of the second rod, and wherein the first and second rods are parallel to the first and second sides of the card holder, respectively, and in the working state, the push pin is applied to the first rod, such that the first rod moves in the direction along which the push pin is applied and drives the second rod to move in a levering motion manner, wherein an end of the second rod acts as a force bearing point that applies to an inner side of the card holder to make the card holder move outwardly relative to the receiving space, wherein the inner side is a side of the card holder relative to the inside of the receiving space. ### Claim 4 (depends on 1) The SIM card seat according to claim 1, wherein the card holder comprises a body having a recess for receiving the SIM card. ### Claim 5 (depends on 4) The SIM card seat according to claim 4, wherein the card holder is integrally structured. ### Claim 6 (depends on 4) The SIM card seat according to claim 4, wherein the card holder is separately structured. ### Claim 7 (depends on 6) The SIM card seat according to claim 6, wherein the body comprises a frame and an insert block which are connected to each other in a separate manner, and wherein the frame is configured to receive the insert block, and the recess is disposed in the insert block. ### Claim 8 (depends on 2) The SIM card seat according to claim 2, wherein the card holder comprises a body having a recess for receiving the SIM card. ### Claim 9 (depends on 8) The SIM card seat according to claim 8, wherein the card holder is integrally structured. ### Claim 10 (depends on 8) The SIM card seat according to claim 8, wherein the card holder is separately structured. ### Claim 11 A mobile terminal, comprising a SIM card seat for receiving a SIM card, and a motherboard on which the SIM card seat is positioned, wherein the SIM card seat comprises a housing, a signal conducting terminal, a card holder and an ejector, the signal conducting terminal is disposed on the motherboard for conducting with the SIM card, a receiving space is formed between an area of the motherboard where the signal conducting terminal is located and the housing, which is configured to receive the card holder and the ejector, the card holder is configured to receive the SIM card and match different types of SIM cards, the ejector is configured to eject the card holder out of the SIM card seat from the receiving space. ### Claim 12 (depends on 11) The mobile terminal according to claim 11, wherein the card holder comprises a first side and a second side adjacent to the first side, and the ejector comprises: a second rod positioned at the second side and rotatable in the plane of the SIM card seat; a first rod positioned at the first side and movable in a direction substantially perpendicular to the second rod to make the second rod rotate via the engagement there between; and a push pin configured to drive the first rod to move in the direction substantially perpendicular to the second rod. ### Claim 13 (depends on 12) The mobile terminal according to claim 12, wherein the ejector has switchably a normal state and a working state, wherein: in the normal state, the first rod and second rod are positioned perpendicular to each other in the receiving space, wherein an end of the first rod is positioned close to a head of the second rod, and wherein the first and second rods are parallel to the first and second sides of the card holder, respectively, and in the working state, the push pin is applied to the first rod, such that the first rod moves in a direction along which the push pin is applied and drives the second rod in a levering motion manner, wherein an end of the second rod acts as a force bearing point that applies to an inner side of the card holder to make the card holder move outwardly relative to the receiving space, the inner side is a side of the card holder relative to the inside of the receiving space. ### Claim 14 (depends on 11) The mobile terminal according to claim 11, wherein the card holder comprises a body having a recess for receiving the SIM card. ### Claim 15 (depends on 14) The mobile terminal according to claim 14, wherein the card holder is integrally structured. ### Claim 16 (depends on 14) The mobile terminal according to claim 14, wherein the card holder is separately structured. ### Claim 17 (depends on 16) The mobile terminal according to claim 16, wherein the body comprises a frame and an insert block which are connected to each other in a separately manner, and wherein the frame is configured to receive the insert block, and the recess is disposed in the insert block. ### Claim 18 (depends on 12) The mobile terminal according to claim 12, wherein the card holder comprises a body having a recess for receiving the SIM card. ### Claim 19 (depends on 18) The mobile terminal according to claim 18, wherein the card holder is integrally structured. ### Claim 20 (depends on 18) The mobile terminal according to claim 18, wherein the card holder is separately structured.
