An electrical core of an aircraft is provided. The electrical core includes at least one shelf on which is disposed at least one module containing components and comprising at least one input able to be linked to at least one power supply cable and at least one output able to be linked to at least one output cable. In the module, the output cable or cables travel under or in the shelf disposed under the module.

An electrical cabinet of an aircraft is provided. The electrical cabinet includes at least one motherboard including on a first face sockets into which are plugged PCB boards ensuring one or more electrical functions, the said electrical cabinet being linked to the electrical circuit of the aircraft organized as various electrical harnesses by way of an electrical connection system, characterized in that the electrical connection system comprises at the level of the second face of the motherboard at least one additional layer, the free face of the last additional layer comprising sockets each ensuring electrical connection with an electrical harness of the aircraft, the additional layer or layers comprising tracks which make it possible to reorganize the electrical circuits emanating from the sockets intended for the PCB boards so as to render them compliant with the sockets intended for the harnesses of the aircraft.

A backplane and a communications device are disclosed. The backplane includes: at least one fixing plate, multiple connectors, and multiple flexible cables, where signal connection is implemented between corresponding connectors by means of the flexible cables, each of the connectors is provided with a housing and multiple signal pins installed on the housing, and the housing is installed on the fixing plate and is provided with a jack for insertion of a connector of a subcard in the communications device; one end of each signal pin is inserted into the jack, and the other end is connected to each flexible cable. When the communications device provided with the backplane transmits a high-rate signal, transmission quality and a transmission rate are relatively high.

A method for connecting communication cables includes at least an input cable, an output cable, and a cable adapter. The input cable may include a plurality of input wires, each of the plurality of input wires communicatively connected to an input port. The output cable may include a plurality of output wires, each of the plurality of output wires communicatively connected to an output port. The cable adapter may be for communicatively interconnecting the input cable and the output cable. The cable adapter may include a container, a lid and a plurality of attachment mechanisms. The lid may be movably attached to the container. The plurality of attachment mechanisms may be located in the container, each of the plurality of attachment mechanisms capable of communicatively and reversibly connecting one of the plurality of input wires with one of the plurality of output wires.

A system is provided herein. The system includes a cage and a handle mechanism. The handle mechanism includes a handle member and a cam member. The handle member is formed to rotate between a closed position, a top open position, and a bottom open position. In the closed position, a handle latch holds the handle in the closed position. In the top open position, the handle rotates a first amount to the top open position and engages with a top cam surface. Rotation of the handle member to rotate a cage a second amount. In the bottom open position, the handle member rotates the first amount to the bottom open position and engages with a bottom cam surface. Rotation of the handle member to rotate the cage the second amount. The cam member to control a rate of rotation of the handle member and the cage.

A modular printed circuit board assembly is provided. The modular printed circuit board assembly includes a housing unit. The housing unit includes a plurality of connectors, a heat transfer unit, and an identification unit. The plurality of connectors connects a host interface board of a plurality of host interface boards with a plurality of module boards and connects a module board of the plurality of module boards with the plurality of host interface boards. The host interface board includes information about an electronic device. The heat transfer unit dissipates the heat to a heat sink. The heat sink is a passive heat exchanger for conducting the heat generated by the electronic device. The identification unit is configured to read the unique identification of the electronic device from the host interface board to determine a structural combination of the electronic device.

The in-drawer power management system and methods can include a power outlet charging receptacle dock; a power cord electrically coupled to the power outlet charging receptacle dock; a flexible power cord retainer configured to confine the power cord therethrough; a magnetic mounting plate having an alignment mounting location and a final mounting location, and the magnetic mounting plate configured to align the flexible power cord retainer by magnetic force; and a magnetic mounting bracket configured to align to the alignment mounting location or to the final mounting location through magnetic force.
