A card connector includes: an insulative body; plural contacts secured to the insulative body; and an operating mechanism including a latch moveable relative to the insulative body and an actuator coupled to the latch, wherein: the actuator includes a pair of terminals, a slider coupled to one of the pair of terminals, and a shape memory alloy wire coupled between the other terminal and the slider; and the slider is operable by the shape memory alloy wire to move the latch from a card-locking position to a card-unlocking position.

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 tray is insertable forward in a front-rear direction into a connector main of a card connector. The tray has a first card accommodation portion and a second card accommodation portion. The first card accommodation portion is positioned at a position different from a position of the second card accommodation portion in an up-down direction perpendicular to the front-rear direction. The first card accommodation portion has a first elastic beam portion, a first facing portion and a first bulge. The second card accommodation portion has a second elastic beam portion, a second facing portion, and a second bulge. The first elastic beam portion and the second elastic beam portion are positioned at positions different from each other in the front-rear direction. The first elastic beam portion and the second elastic beam portion are elastically deformable independently of each other.

A magnetic card reader is provided and includes the holder which is movable both in the card-inserting direction and the card-ejecting direction in the card pathway. The magnetic card is held in the holder which is energized in the card-ejecting direction. Therefore, when the card latch lever is retracted, the auto eject operation of the magnetic card is implemented. The distance between the card-receiving surface on the holder positioned in the insertion-waiting position and the reading-writing position in the X direction is longer than the length from the edge of the magnetic card on the back side X2 to the edge of the magnetic data recording range on the front side X1. Therefore, the magnetic card is prevented from hitting the card-receiving surface and therefore from receiving impact while the magnetic data recording range on the magnetic card is passing the reading-writing position.

A card connector assembly includes: an electrical connector (100) including a main body, plural contacts in the main body, and a tray guiding mechanism, the tray guiding mechanism including a slider (17), a pin member (19) coupled between the slider and the main body, a latch (20) moveable with the pin member, and an actuator; and a card tray (200) moveable together with the slider in the main body; wherein the actuator includes a bolt (16) slidably mounted in the main body, and the slider is moveable by the card tray to move the pin member and the latch against a biasing force to lock the latch to the bolt.

A withdrawable-card-tray position-fixing structure for an electronic device, which is adapted to allow a tray having a card mounted thereon to be stably positioned within the device, is provided. The structure has a tray and a tray position-fixing member. The tray has a mounting hole formed in a card-mounting section thereof where the card is mounted. The tray position-fixing member is formed from a resilient material that is itself resilient while having a large surface coefficient of friction. The tray position-fixing member is mounted either on the tray itself, in a tray insertion pathway or both, and into which the tray is inserted by being press fitted therein. The structure is adapted to achieve an improved force of friction between the tray position-fixing member and a counterpart member which comes into contact therewith, and achieves an improved tray position-fixing capability via the press fitting of the tray.

A card connector including a body, a slider, a lock spring, and an urging member. The body includes a movement path and an abuttable portion. The slider is movable in Y-Y direction inside the movement path. The lock spring is provided at the slider 300 and is movable in the same direction. An engaging portion of the lock spring is engageable with an engaging recess of a card. The urging member in the Y direction moves the slider from a first position to a second position and brings the engaging portion into abutment with an inclined face of the abuttable portion. In a state where the slider is located at the second position and the engaging portion abuts the inclined face, a load is exerted from the card to the engaging portion, and the engaging portion is displaced in the X direction along the inclined face.
