The accommodation space is configured to accommodate a data storage device. The first opening and the second opening are connected to the accommodation space, and the mount portion protrudes from the first opening. The circuit board is fixed on the mount portion. The circuit board has a first electrical connector and a second electrical connector located at opposite surfaces of the circuit board and having different interfaces, and the first electrical connector is configured for an insertion of the data storage device. The mount seat has a first guiding portion, the cage has a second guiding portion mating with the first guiding portion. The fastener is configured to fix the cage to the mount seat.

An interface card cage includes a first assembly and a second assembly. The first assembly includes a first side wall, a second side wall, and a bent portion. The second side wall has an opening. The bent portion and the first side wall extend in different directions. The bent portion includes a protrusion extending from the bent portion. The second assembly includes an assembly part having a slot. The assembly part includes a first side plate and a second side plate. The first side plate has a recess. The assembly part has a first edge and a second edge. A direction from the first edge to the second edge is different from a direction from the first side plate to the second side plate. The bent portion of the first assembly is located in the slot. The protrusion is located in the recess.

A system chassis includes a housing and a card cage. The card cage is positioned at a first end of the housing. The card cage includes a plurality of cavities arranged to receive (i) a lower row of expansion device cards arranged in a first orientation, and (ii) an upper row of expansion device cards arranged in a second orientation, which is upside down from the first orientation.

A method is provided for mounting a semiconductor IC to a substrate without a socket or solder. The method includes disposing a guide structure on the substrate. The substrate has multiple contact pads disposed thereon. The substrate also has multiple nuts formed therein for connecting to one or more bolts. The method also includes placing the semiconductor IC inside the guide structure such that the semiconductor IC makes contact with the contact pads. A top plate is disposed on the semiconductor IC. Further, the top plate and the semiconductor IC are fastened to the substrate.

The invention relates to a reference potential assembly and an attachment assembly for an electrical circuit, the assembly having an electrically conductive flexible clip (30) which includes: an electrical circuit clamping conductor clamp; an electrical contact stub (42); an attachment (43) adapted to clamp the electrical contact stub (42) against an electrical contact surface.

An electronic device includes a housing and a first heat source, a second heat source, and a heat dissipation module that are disposed in the housing. The heat dissipation module includes a first fan, a second fan, a first heat conduction member, and a second heat conduction member. The first fan and the second fan are disposed on two opposite sides of the housing. One end of the first heat conduction member is disposed at the first fan, and the other end is located at a position on a side of an upper surface of the housing corresponding to the first heat source. One end of the second heat conduction member is disposed at the second fan, and the other end is located on a side of a lower surface of the housing and abuts against the second heat source.

A labor-saving mainboard withdrawing structure for electronic devices is used for withdrawing a mainboard from a slot in a withdrawing direction, and the structure includes a fixed seat, a movable seat installed separately on both sides of the fixed seat and limited to move in the withdrawing direction only and having a space defined between the two movable seats for installing the mainboard, and a rail track disposed on an opposite side and extending along the withdrawing direction for slidably inserting the mainboard. Each movable seat has a pushing portion and a pushing member abutting against the mainboard, and each pushing member has a head provided for operator to push, and a tail abutting against the fixed seat, and the head can be pushed to move the tail pivotally, and when the tail is moved pivotally, the movable seat is pushed to move a retreat distance in the withdrawing direction relative to the fixed seat, so as to detach the mainboard from the slot by pushing the pushing portion.
