A card/chassis coupling system includes a chassis defining a chassis housing with a chassis wall defining a card entrance to the chassis housing. The chassis wall engages a securing element on a card to secure it in the chassis housing. A card/chassis release device adjacent the card entrance includes a base in the chassis housing, and a card mover member and securing element release member that are each moveably coupled to the base and to an actuator member extending through the chassis wall. Movement of the actuator member into the chassis housing causes the securing element release member to move relative to the base to engage the securing element on the card and disengage it from the chassis wall, and causes the card mover member to move relative to the base to engage the card and move it through the card entrance and out of the chassis housing.

A card connector assembly includes: an electrical connector including an insulative housing, a plurality of terminals secured to the insulative housing, a shell covering the insulative housing to form a receiving cavity, and an ejector having a pivot; and a card tray removably received in the receiving cavity, the card tray having a front surface, wherein the card tray has a protrusion at the front surface, and the pivot has an engaging portion for ejecting the card tray, the engaging portion having a recess for receiving the protrusion and an ejecting end for riding onto the protrusion.

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 button assembly includes a pressing element, a tray, and a locking structure fastened between the pressing element and the tray. One side surface of the pressing element is recessed inward to form an accommodating space. The pressing element opens at least one first upper fixing hole. A bottom surface of the pressing element is recessed upward to form a first accommodating slot. The first accommodating slot opens at least one first opening. The tray of which one side is connected with the pressing element. The one side of the tray has a base portion mounted in the accommodating space. The base portion opens at least one second opening. A bottom surface of a peripheral wall of the at least one second opening is recessed upward to form at least one locking slot. The locking structure includes at least one locking element and an elastic arm.

A connector tray inserted into a connector body in an insertion direction while accommodating an object to be connected includes a tray body configured to accommodate the object to be connected, a tray exterior portion connected to the tray body to be displaceable along the insertion direction, and a push-push mechanism disposed between the tray body and the tray exterior portion in a tandem arrangement and configured to displace the tray exterior portion in the insertion direction between a first position away from the tray body and a second position close to the tray body.

A chip card assembly of an electronic device includes a casing defining an opening, a connector received inside the casing and including a tray, an electromagnet driving assembly including at least one electromagnet and a pushing member, and a control unit configured to control the electromagnet driving assembly to drive the pushing member to push the tray out of the opening. The tray includes a cover for covering the opening.

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.

A card holder includes a card tray, a card cover and a first connecting rod. The card tray is configured to accommodate a data card. The card cover is rotatably connected to the card tray, and includes opposite first and second ends and a first protrusion extending towards the card tray. The first connecting rod has an end connected to the card tray and another end rotatably connected to the card cover, and is configured to rotate relative to the card cover such that the card cover approaches to or is away from the card tray. When the card holder is inserted into a housing and a pushing force is applied to the first end, the card cover is rotatable about the first protrusion such that the first end extends further into the housing and the second end extends out of the housing. An electronic device is also provided.

The present disclosure relates to a card socket for an electronic device and, more particularly, to a card socket for an electronic device having an improved card insertion confirmation structure, wherein the structure of a card insertion confirmation terminal, which senses full insertion of a card or a tray into a card socket, is changed so as to improve stability of insertion of the card or the tray.

A waterproof card holder includes a card holder frame, a cover plate, a sleeve integrated with and extending from an inside of the cover plate, and a waterproof mechanism in the sleeve. A through-hole of the sleeve penetrates through the sleeve and cover plate. The waterproof mechanism includes a first end portion limited inside the sleeve, a second end portion having an outer diameter smaller than that of the first end portion, and a waterproof ring sleeved on a periphery of the first end portion and forming a sliding sealing structure with the sleeve. The sleeve includes first and second openings respectively disposed at two ends of a sleeve body. The first end portion is limited to be only movable within a stroke between the first and second openings. The second end portion being capable of passing through a first opening to be in contact with a card retracting mechanism.
