The waterproof mechanism includes a main body, a first end portion located inside the sleeve, a second end portion protruding from the sleeve, and a waterproof ring located on a periphery of the main body and close to the first end portion. The waterproof ring and the sleeve form a sliding sealing structure therebetween.

In a card connector, a main body has a plugging space formed therein and used to locate terminals of a terminal set, two sliding members of a sliding mechanism are movably disposed on two sides of the terminal set in the plugging space, respectively, and each sliding member has a supporting part protruded on a side thereof and extended into the plugging space, and elastic members are abutted between sides of the two sliding members and two opposite sidewalls of the plugging space, respectively; a terminal of a guiding rod is slid along a guiding groove, and an other terminal of the guiding rod is inserted through the main body; a push plate of a shielding housing is abutted with the guiding rod, so that a preset electronic card can be stably inserted into or ejected out of the plugging space through the two sliding members.

Various examples of the present invention relate to a connector device having a multi-receiving part, the connector device enabling a SIM card and an SD card having different sizes to be individually or simultaneously mounted by using one tray, thereby increasing the spatial usability of an electronic device, having advantages in terms of outline design, saving manufacturing costs, and increasing the usability of the electronic device. Various examples, in addition to the examples disclosed in the present invention, are possible.

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.

According to one embodiment, a controller may include a user interface that is operable to receive input from a user to control an electronic system to which the controller may be coupled either directly or indirectly. The user interface may comprise an interface housing to which the user interface is coupled, the interface housing having a front portion and a rear portion, the front portion of which may contain the user interface. A controller housing may be coupled to the rear portion of the interface housing, the controller housing having a smaller perimeter than the interface housing. The controller housing may be comprised of at least one sidewall and a rear wall. At least one magnet may be coupled to the controller housing. The magnet(s) may be operable to hold the controller in position using magnetic force when the controller housing is inserted into a mounting receptacle.

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.

According to various embodiments, an electronic device may include: a housing including an opening connected to an internal space of the electronic device; a tray socket connected to outside the electronic device through the opening in the internal space and including a tray reception space; a tray configured to be inserted into the tray reception space, wherein the tray includes a tray body including at least one space configured to receive at least one external component; and a tray cover including a pin insertion hole configured to guide a tray ejecting pin to the opening; an eject bar movably disposed in a tray mounting direction or ejecting direction in the tray reception space and facing the pin insertion hole; and a rotation lever configured to press the tray in the ejection direction based on pressing of the eject bar in the tray reception space, wherein the eject bar is disposed at a position at least partially overlapping the tray body when viewed from above the tray socket.

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.
