## Background
CROSS REFERENCE TO RELATED APPLICATIONS
This application is a Continuation-In-Part of International Application PCT/CN 2013/078925, with an international filing date of Jul. 5, 2013, which claims priority to Chinese Patent Application No. 201210511367.0, filed on Dec. 3, 2012, both of which are hereby incorporated by reference in their entireties.


TECHNICAL FIELD
The present disclosure generally relates to an electronic product, and more particularly, to a SIM card seat and a mobile terminal.
BACKGROUND
A SIM card is an abbreviation for “Subscriber Identity Module card”, which can also be called smart card or ID card. The SIM card can store user's data, authentication algorithm and key for identifying the subscriber identity by a GSM system. A mobile phone cannot be used without the SIM card. The SIM card is usually positioned in a SIM card seat of the mobile phone.
With the progress of science and the development of mobile communication, the mobile phone is continuously updated in construction, design and performance. In the present market, there are lots of types of mobile phones, and also lots of types of SIM cards fit for the mobile phones. For example, most types of mobile phones use a normal SIM card, while IPHONE 4 and IPHONE 4s use a Micro SIM card, and IPHONE 5 uses a Nano SIM card. The conventional SIM card seat has a card case for receiving the SIM card, and a signal terminal for conducting with the SIM card.
Due to the structural limitation, the SIM card seat of a type of mobile phone can only match a corresponding type of SIM card. That is, one type of mobile phone can only be suitable to receive one type of SIM card. For example, for IPHONE 4, the Micro SIM card cannot be replaced with a Mini SIM card. Therefore, when a user changes his/her mobile phone, he or she has to choose a mobile phone having the same type of SIM card seat in the case that he or she does not want to change the SIM card. Or the user has to give up his/her original SIM card to choose a mobile phone having a different type of SIM card seat to fit for a different type of SIM card, which may be inconvenient for the user and result in waste of resources.

DETAILED DESCRIPTION
In the following detailed description, reference is made to various specific embodiments of the present disclosure. These embodiments are described with sufficient details to enable those skilled in the art to practice the present disclosure. It is to be understood that other embodiments may be employed, and that various structural, logical, and electrical changes may be made without departing from the spirit or scope of the present disclosure. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.
As used herein, a “terminal” may be implemented using a variety of terminal devices. Examples of such terminal devices include mobile phones, computers, digital broadcast terminals, messaging devices, gaming consoles, tablets, pads, medical devices, exercise equipment, personal digital assistants, and the like.
Embodiment 1
As shown in FIG. 1 and also referring to FIGS. 2 to 4, the present disclosure is illustrated mainly based on FIG. 2. The present embodiment of the disclosure provides a SIM card seat which is for receiving a SIM card 60. The SIM card seat may be positioned on a motherboard (not shown) of the terminal device. The SIM card seat comprises a housing 1, a signal conducting terminal 2, a card holder 3 and an ejector 4 (referring to FIG. 4). The signal conducting terminal 2 is disposed on the motherboard to conduct with the SIM card 60. It is contemplated that the SIM card seat may have one or more signal conducting terminals 2, which are isolated from each other and used for conduction with corresponding terminals or nodes at the SIM card 60. A receiving space is formed between the housing 1 and the area of the motherboard where the signal conducting terminal 2 is located, and the receiving space is used for receiving the card holder 3 and the ejector 4 (referring to FIG. 4). The card holder 3 is used for receiving the SIM card 60 and matching different types of SIM cards. The ejector 4 (referring to FIG. 4) is used for ejecting the card holder 3 out of the SIM card seat from the receiving space.
As shown in FIG. 2, according to an embodiment of the present disclosure, the card holder 3 can be ejected out of the receiving space by the ejector 4, and can be replaced by a different type of card holder. In this way, the SIM card seat can match different types of SIM cards 60, thereby the mobile terminal having the SIM card 60 can match various SIM cards. Therefore, it is not required to change the original SIM card 60 to match various mobile phones, which is convenient for the user, provides better user experience, and reduces waste of resources.
For example, as shown in FIG. 2, in the present embodiment, an area of the motherboard where the signal conducting terminal 2 is located is integrally structured with the housing. For example, the housing 3 may be secured with the motherboard, for example, via threaded connection.
It will be appreciated by people skilled in the art that, the area of the motherboard where signal conducting terminal 2 is located may be separately structured with the housing, for example, via clip connection.
For example, as shown in FIG. 4, in the present embodiment, the ejector 4 comprises a first rod 41, a second rod 42 and a push pin 43. The first rod 41 and the second rod 42 are positioned at two adjacent sides of the card holder, respectively. The second rod 42 is rotatable clockwise or counterclockwise in the plane of the card seat, i.e. the plane of FIG. 4. The first rod 41 is movable in a direction substantially perpendicular to the second rod 42, such that the first rod 41 can operatively engage with the second rod 42 to make the second rod 42 rotate. The first rod 41 may move in response to a driving force exerted via the push pin 43. The ejector 4 may have switchably a normal state and a working state according to the engagement between the first and second rods.
In the normal state, the first rod 41 and second rod 42 are positioned perpendicular to each other in the receiving space. An end 41B of the first rod is close to a head 42A of the second rod, and the first rod 41 and the second rod 42 are parallel to two adjacent sides of the card holder, respectively. As the second rod 42 are substantially parallel with the inner side (left side in FIG. 4) of the card holder, the second rod 42 may not enter into the receiving space, thereby not affecting the position of the SIM card 60. Then the SIM card 60 can be completely received within receiving space.
In the working state, the push pin 43 is applied to the first rod 41 by an external force, for example, such that the first rod 41 moves in a direction along which the push pin is applied, i.e. the horizontal direction of FIG. 4. Then the first rod 41 drives the second rod 42 to rotate, i.e. to move in a levering motion manner. As shown in FIG. 4, the second rod 42 rotates counterclockwise such that its end 42B engages with the inner side of the card holder. Further, the end 42B of the second rod acts as a force bearing point acting on the inner side of the card holder to make the card holder move outwardly relative to the receiving space. The inner side of the card holder is the side relative to the inside of the receiving space.
It should be noted that, the terms “head” and “end” are defined relatively. In the present embodiment, the end part of the first rod 41 that contacts the push pin 43 is defined as the head of the first rod 41, thus the other end part of the first rod 41 is defined as the end of the first rod 41. The end part of the second rod 42 that contacts the first rod 41 is defined as the head of the second rod 42, thus the other end part of second rod 42 is defined as the end of the second rod 42.
