Disclosed are a card tray, a card connecting apparatus and a mobile terminal. The card connecting apparatus includes a card tray and a base. The base is configured to contain the card tray. The card tray includes an ejecting mechanism and a card carrying mechanism. The card carrying mechanism is provided with a sliding cavity. The ejecting mechanism includes a pull rod slidably arranged in the sliding cavity to form a card-rod separated structure that the ejecting mechanism is capable of pushing the card carrying mechanism into the base or pulling out the card carrying mechanism from the base and also capable of being ejected alone when the card carrying mechanism is clamped in the working position by the base.

A connector module is mounted at a portable electronic device. The portable electronic device includes a housing and a circuit board. The circuit board is disposed in the housing, and the housing has an opening. The connector module includes a switch component, a connector and a button assembly. The switch component is disposed at the housing and is electrically connected with the circuit board. The connector is movably disposed between the opening and the switch component, and the connector is electrically connected with the circuit. The connector is for accommodating an IC card, so that the IC card is capable of being electrically connected with the circuit board via the connector. The button assembly is inserted at the opening and abuts against the connector, and drives the connector to touch the switch component when being pressed.

A rotary tray holder includes a tray holder comprising a side A and a side B, each side comprising at least one window to hold a SIM card; and a handle grabber that allows rotation of the tray holder to enable insertion of the tray holder in an electronic device with any of the side A and the side B of the tray holder, thereby enabling the SIM card located on the side oriented in the desired direction to be active, and making the SIM card located on the other side to take a standby position. The tray holder may include two partly overlapping windows oriented at an angle to each other. One of the overlapping windows holds the SIM card with contacts providing a standby position for the SIM card that may be repositioned in the other of the two overlapping windows to make the SIM card active.

A card holding member is provided which is able to hold a card having terminal members and is able to be inserted into a card connector. The card holding member includes a card holding frame portion facing the side surfaces of the card, and a first portion including a first connecting portion. The card holding member further includes a main body portion, and a second portion including a second connecting portion connected to the first connecting portion. The card holding member further includes a first elastic member mounted on the outer periphery of the main body portion. The card holding member further includes a second elastic member mounted between the first connecting portion and the second connecting portion.

Electronic devices are provided with ejectable component assemblies. Each ejectable component assembly may include a tray that can be loaded with one or more types of removable module, such as a mini-SIM card and a micro-SIM card, and inserted into the device. Each assembly may also include a cover coupled to a circuit board. The tray may be inserted through an opening in the electronic device and into a space between the cover and the circuit board. A portion of the space is contained within the pocket. A portion of the tray may be contained within the pocket when the tray is inserted into the device for holding the module at a functional insertion position within the device.

A casing and an electronic device using the same are provided. The casing includes a housing, a cover and a connection element. The housing has an opening. The cover selectively covers or exposes the opening and includes a release portion. The release portion is for releasing a component located within the housing. The connection element connects the cover and the housing.

A card connector is provided having a housing and a contact. The housing includes a card receiving space. The contact is supported by the housing and includes a contact arm and an extended portion. The contact arm includes a free end and the extended portion includes a first end positioned below the contact arm on which the free end of the contact arm slides.
