Problems solved by technology
[0008] Most of the time not all contact points of the connector are used, but about 30%-40% of the connection capacity of the connector is used, which obviously leads to loss of space, increased weight and prohibitive cost
[0009] In addition, every change in the configuration of the computer network architecture results in a difficult and time-consuming cabling modification process

Embodiment Construction
[0040] First, the present invention relates to an interconnection system based on the structure of a multifunctional cabinet and wireless communication.
[0041] The prior art on avionics cabinets is at figure 1 and figure 2 displayed in .
[0042] figure 1 A rear detail view of the cabinet is shown, wherein the electrical connectors bl, b2 are able to connect the cable strands cl, c2 to the computers arranged in the cabinet.
[0043] figure 2 An example of the electrical wiring of such a cabinet is shown, it is easy to see the complexity of such wiring c in parallel with the cooling devices e, f of the computer d.
[0044] applied to e.g. image 3 and Figure 6 The purpose of the inventive multifunctional structure 1, 3 of the cabinet shown in , is to significantly simplify this cabinet and, in addition to ensuring the transmission of communications between the computer in the cabinet and the rest of the aircraft's equipment, also ensure electrical or Power supply an...

The invention relates to an input / output device (22) for an electric or electronic cabinet grouping together a plurality of devices such as computers (10a, ..., 10f), characterised in that it comprises: a plurality of input / output channels (23a, 23b, 23c, 23d), conversion units (25, 26, 28, 29) and at least one computing unit (27), said conversion units being connected to the input / output channels and to the computing unit; a digital network link protocol management unit (27a) connected to the computing unit and to at least one transceiver module (24); and software suitable for the digital transmission of data representative of input / output values from / to network computers (10a, ..., 10f) via said at least one transceiver module (24). The invention also relates to an electric cabinet grouping together a plurality of computers, each provided with a transceiver module and comprising an input / output device according to the invention.
Description
technical field [0001] The invention relates to an input / output device for an electrical cabinet, in particular an electrical cabinet of an aircraft or an electrical cabinet of the electronics cabinet type. [0002] The invention finds particular application in cabinets for electrical equipment, such as those that group together computers in an aircraft. Background technique [0003] In current aircraft, computers are grouped together in electrical cabinets, especially for ease of maintenance and ease of operation. [0004] Cabinets, also known as electrical racks or avionics racks, have three main functions. Interconnect function: Data exchange and power supply unit that connects computers clustered in a cabinet between devices and connects computers to these computers; Mechanical function: Keeps the computer of the unit in place; Cooling function: Connects the cooling system of the unit Connecting directly to the cabinet allows cool air to circulate through the cabinet's...
