The self-tapping screw is screwed into the approximately triangular hollow structure.

Abstract: A protective structure includes a covering body, a protective component, a fixing component and a fastening portion. The covering body is for covering the connector. The protective component is connected to the covering body and for plugging into the connector. The fixing component is connected to a side of the covering body and for plugging into an installation hole on a case of the electronic device. The fixing component includes a shaft for pivoting relative to the case so as to drive the covering body to a position where the covering body does not cover the connector when the protective component does not plug into the connector. The fastening portion is installed on the fixing component and is for contacting against the installation hole after the fixing component is plugged into the installation hole so as to prevent the fixing component from separating from the installation hole.

Abstract: An electronic apparatus includes a shell base, a shell cover and a latch mechanism including an operating component, a pivot axle and a driving axle. The operating component has an access portion and two support portions extending through the shell cover. The pivot axle extends through the support portions, and has two end parts disposed at opposite lateral sides of the support portions and coupled rotatably to the shell cover. The driving axle extends through the support portions and is received in a limit groove of the shell base. The access portion is pivotable about the pivot axle from a closed position to an open position while the driving axle is positioned in the slide direction, thereby moving the pivot axle and the shell cover relative to the shell base.

Abstract: A panel having positioning function is disclosed in the present invention. The panel includes a body covering an opening on an extrusion casing, and a positioning mechanism having at least one position set. The position set includes a first rib disposed on a first side of the body, a first contact portion disposed on the first rib and contacting against an inner surface of the extrusion casing, a second rib disposed on a second side of the body, and a second contact portion disposed on the second rib and contacting against the other inner surface of the extrusion casing. A position of the second rib on the second side is symmetrized to a position of the first rib on the first side, so that the panel can align with the extrusion casing due to deformation of the position set.

Abstract: A case is disclosed. The case includes a main body and a container housing tank. The main body includes a surface, and the container housing tank is located on the surface and used to accommodate a nameplate. The container housing tank includes a main tank and a margin tank, wherein the main tank has a first depth; the margin tank is located on the edge of the main tank and connects with the main tank. The margin tank has a second depth that is greater than the first depth.

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.

Abstract: A door panel opening and closing device for a casing includes a face panel, a door panel, and a resilient member. The face panel includes a base wall and a first post disposed on the base wall. The door panel includes a pivot arm pivoted to the base wall and having a second post. A pivot juncture between the pivot arm and the base wall is defined as a turning axis. The door panel is turnable about the turning axis between closed and open positions. The resilient member is an extension spring having two ends hooked to the first and second posts, respectively. When the door panel is turned from the closed position past a specific angular position, the door panel will automatically spring to the open position by virtue of a directional change of a component of tension force of the resilient member to an outward direction.

Abstract: A button structure includes a pressing portion, and an accommodating portion connected to a side of the pressing portion. An accommodating space is formed inside the accommodating portion. The button structure further includes a protruding portion connected to a side of the accommodated portion for actuating a switch when the pressing portion is pressed, and a light guiding portion. An end of the light guiding portion is disposed above a light source, and the other end of the light guiding portion is disposed inside the accommodating space. The light guiding portion is for guiding light emitted from the light source to project on a bottom of the pressing portion.

Abstract: A closure device includes: a main body having first and second shoulders; a door secured rotatably to the main body and having first and second door edges; an engaging member; an engaging mechanism; and a second pivot axle. The first shoulder and the first door edge respectively have a through hole and a first axle hole. The engaging member and the engaging mechanism are disposed respectively at an inner side of the main body. The engaging member includes a first pivot axle extending through the through hole and the first axle hole, and a positioning piece extending radially from the first pivot axle and engaging the engaging mechanism. One of the second shoulder and the second door edge has a second axle hole, while the other of the second shoulder and the second door edge has the second pivot axle extending through the second axle hole.

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: A button structure for actuating a switch includes a pressing part, a protruding part connected to a side of the pressing part for being driven to actuate the switch when the pressing part is pressed, and a constraining part.
