Abstract: A heat dissipation simulator of a component on a printed circuit board (PCB) includes a simulation board and a simulated heat source. The simulation board includes an iron layer and a plastic layer. The simulated heat source includes a simulation chip, a thermal, and a heat sink. The simulation chip, the thermal piece, and the heat sink are mounted on the simulation board in that order. The heat dissipation simulator replaces a sample of the PCB with the component for simulating working states of the component on the PCB.

Abstract: A wind charger set on a circuit board for powering a button cell held by a holder set on the circuit board. The wind charger includes a bracket attached to the holder, a wind turbine fixed on the bracket and a charge circuit. The charge circuit is set on the circuit board. The wind turbine transfers airflow created by a heat-dissipating device set on the circuit board into electricity for powering the charge circuit, which charges the button cell.

Abstract: A mounting apparatus for a solid state disk includes a bracket and a latching module. The bracket includes a connecting pole and a supporting member mounted to the connecting pole. The latching module is installed to the supporting member, and comprises a latching member. The supporting member includes a position pole mounted to the connecting pole and a supporting bar perpendicularly extending out from the position pole. The position pole defines a latching slot facing the supporting bar for positioning an end of the solid state disk. The supporting bar defines a guiding slot facing the latching slot for receiving a side of the solid state disk. The latching member is to latch onto the solid state disk.

Abstract: A device for mounting a riser card includes a base board forming two rods, a motherboard forming an expansion slot to connect the riser card, and a fixing member having two legs at opposite ends. The rods extend through the motherboard and are positioned at opposite ends of the expansion slot. Each rod contains a resilient member inside, and a ball mounted to the resilient member and partly extending out of the rod. The riser card is fixed to the fixing member. Each leg defines a cylindrical hole fitted about one of the rods. The balls partly extend out of the corresponding rods and block tops of the corresponding legs.

Abstract: A socket assembly includes a base and a number of sockets. The base includes a bottom wall and two sidewalls. A conductive base is formed on the bottom wall and forms at least two conductive pieces parallel to the sidewalls. An extension plate extends from the top of one of the sidewalls toward the other sidewall. A number of cutouts are defined in the bottom surface of the extension plate. Each socket includes a main body and a fixing member mounted on the top of the main body. The manipulation of the fixing member allows the repositioning of a socket within the base, or the removal of a socket.

Abstract: A connector retaining device for retaining interconnection between two connectors a support board and two flexible fastening strips. The support board includes two through holes. The flexible fastening strips respectively extend through the through holes. Each fastening strip includes a loop at one end thereof, the other end of the fastening strip is passable through the loop. The fastening strips are configured for embracingly gripping the cables at opposite sides of the combined connectors and sandwiching the combined connectors therebetween.

Abstract: A connector retaining device for retaining interconnection between two connectors includes an upper frame and a lower frame. The upper frame includes two parallel side members and two parallel end members connected between opposite ends of the side members. Each side member includes a cutout defined in an upper edge thereof and a hook extending downwardly beyond a lower edge thereof, each end member defines a recess in a lower edge thereof. The a lower frame includes two parallel side members and two parallel end members connected between opposite ends of the side members. Each side member included a cutout defined in a lower edge thereof and a hook extending upward beyond an upper edge thereof, each end member defines a recess in an upper edge thereof. The upper frame is attachable to the lower frame for sandwiching the combined connectors therebetween and surrounding the combined connectors therein.
