Abstract: An electronic device includes a printed circuit board (PCB), at least one socket mounted to the PCB, at least one connector inserted into the at least one socket, a first member mounted to the PCB, a second member mounted to the PCB, and a first cover. The first cover covers and presses against the at least one connector, the first cover includes a first end for being fixed to the first member and a second end opposite to the first end for being fixed to the second member. At least one of the first member and the second member is soldered to the PCB, and a soldered area of the at least one of the first member and the second member is larger than a predetermined value.

Abstract: An electronic device includes a housing, and a card holding mechanism for holding an electronic card. The housing defines a through hole, and the card holding mechanism may be inserted into the housing via the through hole. The card holding mechanism includes a tray for receiving the electronic card, an operating component, and a transmission component. The operating component moves from a latched position to an unlatched position, the transmission component is driven by the operating component to rotate and drive the tray to eject from the housing.

Abstract: A fastening mechanism for fastening a first object to a second object, the fastening mechanism includes a first fastening member, a driven member, a linkage member, and a first supporting member. The first fastening member is rotatably secured to the second object. The driven member is rotatably secured to the second object. The linkage member is connected between the fastening member and the driven member. The first supporting member protrudes from the second object to support the first object. When an external force is exerted on the driven member, the driven member is capable of rotating to pull the linkage member, thus the linkage member pulls the first fastening member to rotate toward the first supporting member and sandwiches the first object between the first fastening member and the first supporting member so that the first object is fastened to the second object.
