Disclosed is an electronic device including a housing; a tray socket provided in the housing; a tray configured to be inserted into the tray socket along an insertion direction; and an ejector configured to be connected to the tray socket and configured to press and separate the tray in a separation direction opposite to the insertion direction. The tray includes a first body configured to detachably couple with the tray socket including a seating portion configured to accommodate and support an external part; a second body configured to slidably couple with the first body along the insertion direction; a tray cover configured to be connected to the first body and exposed to the outside based on a state in which the tray is inserted into the tray socket and in which a pin insertion hole configured to enable communication between the second body and the outside is formed.

A waterproof mechanism includes a telescopic member; a thrusting member; and a sleeve. The telescopic member includes a retractable telescopic base, and an opening provided on an upper end of the telescopic base. The thrusting member includes a head portion and a rod portion having an outer diameter smaller than that of the head portion. The sleeve includes a cavity penetrating through both ends of the sleeve. The sleeve is sleeved on the rod portion of the thrusting member, a part of the thrusting member and a part of the sleeve are inserted into the opening of the telescopic base. The head portion of the thrusting member is held between the telescopic base and the sleeve, and an inner wall surface of an upper portion of the opening of the telescopic base and an outer wall surface of a lower portion of the sleeve are in a waterproof connection.

A storage chassis may be adapted, or configured, to secure a plurality of carrierless devices (e.g., without the use of a carrier or drive tray) received thereby. The storage chassis may include a base, a first drive wall coupled to and extending from the base, and a second drive wall coupled to and extending from the base. The first drive wall may be spaced apart from the second drive wall. The base, the first drive wall, and the second drive wall may define a row of drive slots and each drive slot of the row of drive slots may be configured to receive a carrierless device. Further, the storage chassis may include a plate extending across the row of drive slots and may be configured to extend over the carrierless devices received by the row of drive slots.

A double-lever handle includes a main handle and an assisting handle. The main handle is rotationally mounted to a support body to form a first rotating pair. The assisting handle includes a power arm portion. The power arm portion is rotationally coupled to an end of the main handle away from the first rotating pair to form a second rotating pair. An end of the main handle adjacent to the first rotating pair defines a first latching slot. The main handle rotates about a first latching pin latched in the first latching slot. An end of the power arm adjacent to the second rotating pair defines a second latching slot. The power arm rotates about a second latching pin latched in the second latching slot.

A card socket component for an electronic device includes a housing, a bearing plate fixed in the housing, a card holder, and an elastic component. The housing has a through hole. The card holder has a tray and a baffle connected to the tray. The tray passes through the through hole of the housing, and is slidably connected to the bearing plate. The elastic component includes an elastic member and a lever. The elastic member is elastically disposed on the bearing plate in a sliding direction of the card holder. The lever is rotatably connected to the bearing plate, a first end of the lever abuts against the elastic member, and a second end of the lever is able to abut against the tray. Also provided is an electronic device.

A card tray opening/closing mechanism, used for shifting a card in or out of a slot of a mobile phone body. The card tray opening/closing mechanism comprises a transmission assembly and a micro motor; the micro motor is fixedly connected in the mobile phone body, and is used for communicationally connecting to the mobile phone body. The micro motor is connected to the transmission assembly; the transmission assembly is used for connecting to the card tray body; and the micro motor can shift the card tray body in or out of the slot by means of the transmission assembly.

Electronic devices are provided with ejectable component assemblies. The ejectable component assembly may include a tray that can be loaded with one or more removable modules, wafers coupled to circuit boards, cages and retaining plates to assist in retaining the tray within the assembly. The ejectable component assembly may include springs operative to engage detents in the tray to retain the tray in the assembly. The ejectable component assembly may include a tray ejector mechanism for ejecting the tray from the assembly.

A chip card fixing assembly is received inside a charging interface of an electronic device for fixing a chip card inside the charging interface. The chip card fixing assembly includes a resisting assembly including at least one pushing member and a securing member including at least one fixing portion. The at least one fixing portion and the at least one pushing member cooperatively define a securing space therebetween for fixing the chip card.

A card socket component for an electronic device includes a housing, a bearing plate fixed in the housing, a card holder, and an elastic component. The housing has a through hole. The card holder has a tray and a baffle connected to the tray. The tray passes through the through hole of the housing, and is slidably connected to the bearing plate. The elastic component includes an elastic member and a lever. The elastic member is elastically disposed on the bearing plate in a sliding direction of the card holder. The lever is rotatably connected to the bearing plate, a first end of the lever abuts against the elastic member, and a second end of the lever is able to abut against the tray. Also provided is an electronic device.

An embodiment of a latch apparatus for a circuit board comprises a first latch body with a retention mechanism for the circuit board, a second latch body with a coupling mechanism for a connector, and a spring mechanism mechanically coupled between the first latch body and the second latch body. Other embodiments are disclosed and claimed.
