Abstract: An electronic device includes a metallic housing having a front wall with a mounting hole communicating with an interior thereof, and a front cover spaced apart from the front wall and having an access slot corresponding in position to the mounting hole. A circuit module includes a circuit board disposed within the metallic housing and having an extension protruding out of the front wall via the mounting hole, and an electrical connector disposed on the extension. A conductive ground element is disposed pivotally within the metallic housing in proximity to the mounting hole, and abuts against the electrical connector to conduct static electricity of the electrical connector to the metallic housing.

Abstract: A fan holder for holding a fan is disclosed. The fan holder includes a frame for containing the fan, at least one hook for hooking the fan when the fan is contained inside the frame, at least one resilient arm connected to the frame for resiliently contacting the fan base when the frame is installed inside a fan base, and at least one resilient clip connected to at least one lateral side of the frame for wedging inside a slot formed between the fan base and a casing when the frame is installed inside the fan base.

Abstract: An internally threaded post adapted to be fixed to a first shell is provided. The first shell has a boss, and the boss has an opening. The internally threaded post includes a screwing portion and a fixing portion. The screwing portion has a threaded hole, in which an outer diameter of the screwing portion is larger than an inner diameter of the opening. The fixing portion is connected with the screwing portion, in which an outer diameter of the fixing portion is smaller than the outer diameter of the screwing portion, and the fixing portion is fixed in the opening. In addition, an assembling structure having the internally threaded post and an assembling method are also provided.

Abstract: A riser card module includes a frame body, a carrier plate connected to the frame body for abutment against first surfaces of positioning plates of fixing brackets of expansion cards, a riser card disposed on the frame body and having a plurality of expansion slots for insertion therein of the expansion cards, respectively, and a limiting unit rotatable relative to the carrier plate about an axial direction which is perpendicular to a longitudinal direction of the carrier plate for abutment against second surfaces of the positioning plates of the fixing brackets of the expansion cards so as to restrict movement of the expansion cards relative to the riser card.

Abstract: The fixing device of the present invention comprises a base, at least one light guide pillar, and at least one light-blocking element. The base comprises at least one through hole, which obliquely penetrates the base. The at least one light guide pillar is disposed on the base. The at least one light-blocking element corresponds to the at least one through hole; therefore, when the at least one light-blocking element passes through the at least one through hole, the base and the light guide pillar are fixed by the at least one light-blocking element.

Abstract: An electronic device of the invention includes a main chassis, an electronic module, a cage and an EMI shielding structure. The main chassis has an opening. The cage is assembled to the main chassis and covers the opening. The electronic module is disposed in the cage. The EMI shielding structure includes a conductive frame and at least one first conductive spring clip. The conductive frame is assembled to the cage and electrically connected to the electronic module. The first conductive spring clip is connected to the conductive frame and contacts the main chassis, in which an electromagnetic wave emitted by the electronic module sequentially passes through the conductive frame and the first conductive spring clip to be transmitted to the main chassis.

Abstract: A casing includes a casing module and a support module. The casing module includes two side plates spaced apart from each other, a top-plate unit disposed between and perpendicular to the side plates, and a bottom plate spaced apart from and parallel to the top-plate unit. The side plates, the top-plate unit and the bottom plate define a first accommodating space for receiving a first electronic device. The support module is disposed between the top-plate unit and the bottom plate, and is removably caught in the top-plate unit to divide the first accommodating space into two second accommodating spaces for receiving two second electronic devices that differ in size from the first electronic device.

Abstract: A case structure is disclosed. The case structure includes a plastic panel, a case portion, and a plurality of supporting parts. The case portion includes an assembly part. The assembly part is connected to the plastic panel for assembling. The plurality of supporting parts is connected to the assembly part. The plurality of supporting parts supports the inside of the plastic panel.

Abstract: A locking mechanism includes a lock for passing through an opening of a housing. The lock includes a lock head, a cover whereon a slot is formed, a constraining portion, and a platform structure for contacting against a fastening portion of the housing as the cover passes through the opening. The locking mechanism further includes a tongue piece installed on a side of the cover and rotating with the lock head synchronously. The tongue piece includes a latching portion for latching inside an indentation of a door as the tongue piece rotates to a latching position, and a stopping portion for contacting against an end of the constraining portion as the tongue piece rotates to the latching position. The locking mechanism further includes a jump ring for engaging inside the slot on the cover so as to fix the lock inside the housing.
