An electronic device includes a server unit, a storage apparatus, and a heat dissipation apparatus. The server unit includes a bottom plate defining a first air inlet. The heat dissipation apparatus includes an exhaust fan located above the bottom plate and an air adjusting member. The exhaust fan includes a second air inlet aligning with the first air inlet. The adjusting member is slidably located between the first air inlet and the second air inlet. The bottom plate and the storage apparatus cooperatively bound an airflow channel communicating with the first air inlet. The second air inlet is partitioned into a first air inlet communicating with the airflow channel and a second air inlet communicating with the server unit by the air adjusting member. The air adjusting member is operated to slide to change sizes of the first air inlet and the second air inlet.

A cable backplane system includes a tray having a frame with side walls surrounding a raceway. The side walls extend to a front edge of the frame. The tray includes spacers coupled to the tray located proximate to the front edge. Cable connectors are held by corresponding spacers in position relative to the backplane. The cable backplane system includes an electromagnetic radiation (EMR) absorber extending along an opening in the tray to suppress the propagation of EMR into or out of the tray.

A chassis divides vertically, with front and rear sections of the chassis joined immediately adjacent a midplane printed circuit board that supports interconnectivity of electronic circuits. Wiring within the chassis is eliminated through directed connections of all components to the midplane. Minimal hardware is required for securing the front and rear sections together, and therefore accessing the midplane for assembly and service is convenient. All components except the midplane are installed and removed from either the front or rear of the chassis without opening or disassembling the chassis. The chassis layout and features facilitate effective cooling of the components in the chassis.

A multi-layered printed circuit board includes a base member, a lower layer disposed above the base member, an upper layer disposed above the lower layer, and a plurality of vertical spacer posts sandwiched between the lower and upper layers so as to space apart the lower and upper layers from each other. Each spacer post includes an upper portion having an end face abutting against the upper layer and being formed with an inner threaded hole extending inwardly and axially from the end face, and a threaded lower portion. The threaded lower portion of each of the spacer posts extends a through hole in the lower layer to fasten threadedly the base member, and defines an outer diameter that is greater an inner diameter defined by the inner threaded hole in the upper portion.

A connector for connecting first and second parts, e.g., first and second printed circuit boards, includes a post having a first end fixedly connectable to the first part and a second end having an enlarged head, and a support having a base portion fixedly connectable to the second part and an aperture through which the post can be inserted in a first direction. A lever is mounted at a portion between its ends on a pivot provided on the support, the pivot having a longitudinal axis extending in a second direction perpendicular to the first direction. The lever has an engagement surface at one end substantially aligned with the aperture for engaging the enlarged head of the post. An application of force to another end of the lever in a direction opposite the first direction causes the lever to rotate about the pivot, causing the one end of the lever to move in the first direction towards a locked position, and drawing the enlarged head engaged by the engagement surface in the first direction, thereby forcing the first and second parts together.

A bus device, such as a memory board, is provided with a mother board and a daughter board mount at a predetermined distance above the surface of the mother board. The daughter board has integrated circuit components, such a memory chips, mounted on both of its sides. Means are provided for connecting the wires on the daughter board with those of the mother board and for connecting the wires on the mother board with the conductors of a system bus. In the preferred embodiment of the invention the distance at which the daughter board is mounted above the surface of the mother board is less than twice the maximum thickness of the electronic components mounted on the side of the memory board facing the mother board. The portion of the mother board under these components contains no electronic components itself. Instead, that portion of the mother board contains at least one ventilation opening to ventilate the components on the side of the daughter board that faces the mother board. The preferred embodiment allows two layers of chips to be mounted in a computer slot in which the maximum permissible extent to which components may stick out from the back of a bus device is too small to allow chips to be mounted on the back of the mother board.

The disclosure provides a server including a housing, a plurality of hash boards, a power module and an electrical connection board. Each hash board is slidably arranged in a first accommodating space. The plurality of hash boards and the power module are respectively connected to the electrical connection board. The power module supplies power to the plurality of hash boards through the electrical connection board. The electrical connection board includes two conductive connection boards, each of which is provided with a plurality of conductive pins. The pins form multiple pairs of conductive pins in one-to-one correspondence. Each pair of conductive pins corresponds to each hash board and is electrically connected to supply power to the hash board. Each pair of conductive pins is detachably matched with each hash board to connect or disconnect the power supply path of the hash board.
