A system and method are directed to a fan board sled assembly comprising a fan circuit board including a first end and an opposing second end, a fan cage module including a front section for receiving and removably securing the first end of the fan circuit board to the fan cage module, and a guide bracket including a base section for receiving and removably securing the second end of the fan circuit board to the guide bracket. The fan cage module further includes a back section for receiving one or more fan bodies. The combined fan circuit board, fan cage module and guide bracket are a single integrated unit insertable and extractable from a chassis opening of a computer chassis.

Housing structure for PCI Express expansion electronic boards able to mechanically stabilize said PCI Express expansion electronic boards so as to guarantee the correct functioning, performance and integrity of the electric interconnection between them and the basic electronic board to which they are connected if there are mechanical stresses such as knocks or vibrations, in order to be able to use PCI Express expansion electronic boards in the automotive field, or in scenarios characterized by perturbations of the important mechanical type. The present invention also concerns an assembly method of the housing structure.

A stability device comprising a carrier having a first socket and a second socket;

a first circuit board inserted into the first socket; a second circuit board inserted into the second socket, wherein an inside surface of the second circuit board is facing an inside surface of the first circuit board; a center structure positioned between the inside surface of the first circuit board and the inside surface of the second circuit board, wherein the center structure is fixed to the carrier via a stability bar fixed to the carrier; a spring loaded outer structure at least partially surrounding an outside surface of the first circuit board and an outside surface of the second circuit board and to fix the center structure between the inside surface of the first circuit board and the inside surface of the second circuit board, wherein the center structure and outer structure dissipate heat.

A locking assembly for locking a second component to a second component, comprising a stopper, a mounting component, a driving component, and a linkage mechanism. The stopper is configured for connecting to the first component. The mounting component is configured for connecting to the second component. The driving component is slidably connected to the mounting component. A sliding slot is defined on the driving component. The sliding slot includes a locking segment. The linkage mechanism is slidably connected to the mounting component and the driving component. The linkage mechanism includes a first member and a connecting column. The first member includes a first part and a second part coupled to the first part. The first part is coupled to the mounting component, a first slot is defined on the second part. The connecting column is accommodated in the sliding slot and the first slot.

A circuit board is applied to be inserted an expansion card, the expansion card includes a positioning part. The circuit board includes a board body, a slot, a release structure and a transmission mechanism. The slot is disposed on the board body. The release structure is movably disposed beside the slot along a first direction, and includes a first inclined surface and a blocking portion for limiting the positioning part. The transmission mechanism includes a linkage part and a forcing part which are linked with each other. The linkage part is connected to the release structure. When the forcing part receives an external force, the linkage part moves to move the release structure to the first direction, and releases the limitation of the positioning part by the blocking portion.

A case module that is capable of installing a first electronic module and a second electronic module, includes a cage and a restraining component. The first electronic module can move relative to the cage to a first installation position along a first direction. The second electronic module can move relative to the cage to a second installation position along a second direction perpendicular to the first direction. When the first electronic module moves relative to the cage toward the first installation position along the first direction, the restraining component is driven to move relative to the cage toward a restraining position along the first direction. The second electronic module can be stopped by the restraining component when the restraining component is located at the restraining position.

Systems and methods for educational electronics devices such as may be assembled by non-manufacturer builders, including by personal or hobbyist individuals and by groups such as clubs or classes. Methods and systems relate to Surface Mount Device (SMD) use, measurement systems, communications skill acquisition, physical construction of educational electronics, builder construction/configuration and maintenance of devices, subsystem componentry designed for effective use in educational electronics, circuit designs that permit individual builders to construct professional quality devices, and cognitively adapted methods and systems to optimize learning and performance during and after builder assembly.

A pull-out aiding device is configured for mounting on an object, in which a corresponding apparatus is mounted. The pull-out aiding device includes a pulling member and a handle member. The pulling member includes a first pivot section and an abutting section for abutting against the corresponding apparatus to move the latter forward. The handle member includes a second pivot section and an operating section. The second pivot section is pivotally connected to the first pivot section, such that the handle member is turnable about the second pivot section relative to the pulling member and brings the latter to move forward.
