A processing assembly including cage, partition, two sub-cages, two motherboards, two switch boards and at least one bridge board. Partition is disposed in cage so as to divide inner space of cage into first accommodation space and second accommodation space. Two sub-cages are respectively disposed in first accommodation space and second accommodation space. Two motherboards are respectively disposed on two sub-cages. Two motherboards each include a plate and a plurality of processing units disposed on the plate. Two switch boards are respectively disposed on two sub-cages and respectively electrically connected to two motherboards. Bridge board is electrically connected to two motherboards. One of two motherboards is located between one of two switch boards and bridge board, and another one of two motherboards is located between another one of two switch boards and bridge board.

A telescopic fan cage includes a main frame and a side frame which are slidably connected with each other to form a fan installation space. The side frame is capable of sliding toward the main frame to shrink the fan installation space, or sliding away relative to the main frame to expand the fan installation space. An apparatus case includes a casing and the telescopic fan cage. The telescopic fan cage is detachably disposed in the casing. Therein, the side frame is capable of sliding toward the main frame to shrink the fan installation space, so that the telescopic fan cage is at a transit state for moving in or out the casing; the side frame is capable of sliding away relative to the main frame to expand the fan installation space, so that the telescopic fan cage is at an installation state for being fixed in the casing.

A removable mechanism for a hard drive is revealed. The removable mechanism includes an upper substrate and a base plate hanged and sliding below the upper substrate, and a control handle and a sliding board are set between the upper substrate and the base plate to carry each other. The control handle controls a pivot element sliding on an opening of the base plate. By carrying each other to carry a stop element of the base plate, the stop element slides on a concave opening for dismounting a storage device inserted to the removable drawing mechanism. Thereby, the present application is convenient for dismounting the storage device.

A processing assembly including cage, partition, two sub-cages, two motherboards, two switch boards and at least one bridge board. Partition is disposed in cage so as to divide inner space of cage into first accommodation space and second accommodation space. Two sub-cages are respectively disposed in first accommodation space and second accommodation space. Two motherboards are respectively disposed on two sub-cages. Two motherboards each include a plate and a plurality of processing units disposed on the plate. Two switch boards are respectively disposed on two sub-cages and respectively electrically connected to two motherboards. Bridge board is electrically connected to two motherboards. One of two motherboards is located between one of two switch boards and bridge board, and another one of two motherboards is located between another one of two switch boards and bridge board.

An electronic device includes: a first board configured as a printed circuit board having an electronic circuit component mounted thereon; a second board configured as a printed circuit board having an electronic circuit component mounted thereon; a board-to-board connector configured to electrically connect the first board and the second board, the board-to-board connector including a first terminal on the first board and a second terminal on the second board, the second terminal being configured to be connected to the first terminal; and a grip member on the second board.

An example tool for disconnecting a connector from a circuit board includes: a first arm having first handle and a first notch, where the first notch is for engaging a first connector connected to the circuit board; and a second arm having a second handle and a second notch, where the second notch is for engaging a second connector connected to a cable. A hinge connects the first arm to the second arm. The hinge is biased so that, when the tool is not in use, the first handle and the second handle are farther apart than are the first notch and the second notch.

A push-pull handle module is adapted to lock at least one electronic module in a rack. The push-pull handle module includes a bracket and a handle. The bracket is fixed to the at least one electronic module and includes a slot. The handle is pivotally connected to the bracket and includes a protrusion and a locking portion. The protrusion is slidably disposed into the slot of the bracket. When the handle is in a first position, the locking portion locks rack the at least one electronic module in the rack. When the handle rotates from the first position to a second position relative to the bracket, the locking portion does not lock the at least one electronic module.

A mechanism for servicing a sled installed in a server includes a grip bar, and a four-bar linkage connected to the grip bar. The four-bar linkage has a first position that engages the sled to a chassis of the server, and a second position that disengages the sled from the chassis of the server. Movement of the grip bar moves the four-bar linkage from the first position to the second position, thus disengaging the sled from the chassis and allowing the sled to be removed from the chassis for service.

An electronic device having slots into each of which a circuit board is inserted includes faceplates attached respectively to the circuit boards on the side of an extraction direction. The faceplates each include two handle portions that are disposed respectively at both ends of a main body in the width direction and that extend in the extraction direction. The handle portion of one of two faceplates adjacent in the width direction that is located closer to the other of the faceplates, and the handle portion of the other faceplate that is located closer to the one faceplate, have respective distal ends shifted from each other in a thickness direction.

A faceplate that is attached to a circuit board on the side of an extraction direction in which the circuit board is extracted from a slot includes: a main body that covers an opening of the slot; and two handle portions that are disposed respectively at both ends of the main body with respect to a width direction of the circuit board and that extend in the extraction direction. The two handle portions have respective distal ends shifted from each other in a thickness direction of the circuit board. Multiple slots are formed in a casing of an electronic device along a width direction thereof.
