Abstract

A device for connecting an array of electronic-card-carrying modular structures to an external installation with which a flow of signals can be established, and also providing communication between the various modular structures. The device includes, near the array of modular structures, a plate provided with openings, terminal connection blocks coming from the installation, which should each be inserted into the openings and coupled directly to a connection block carried by a modular structure of the array and, fastened to the plate, a circuit for distributing signals between various modular structures, which is protected from the ambient environment. Such a device may find particular application to aircraft.

Claims

1. Device for connecting an array of electronic-card-carrying modular structures to an external installation with which a flow of signals can be established, this connection device also providing communication between said modular structures, wherein said device comprises, near the array of said modular structures,

a plate provided with openings,

terminal connection blocks coming from the installation, each said terminal connection block being configured to be inserted into one of said openings which supports each said terminal connection block and each said terminal connection block being configured to be coupled directly to a modular structure connection block carried by one of said modular structures of the array;

and,

fastened to the plate, a signal distribution circuit for distributing signals between various modular structures, said circuit being provided with means to protect said circuit from the ambient environment, connected to at least one first-type connection block which is configured to be directly coupled to a block carried by one of said modular structures of the array, this first-type connection block being configured to be inserted into one of said openings in the plate, the openings configured to house the connection blocks whatever their types.

2. Connection device according to claim 1, wherein said means to protect said circuit comprises a protective cap that covers at least the signal distribution circuit placed between the plate and the cap.

3. Connection device according to claim 2, wherein the signal distribution circuit is immobilized between the plate and the cap by at least one first spacer and at least one second spacer, respectively.

4. Connection device according to claim 1, wherein the circuit includes at least one conducting termination cooperating with said first-type connection block.

5. Connection device according to claim 1, wherein, when communication with at least one modular structure external to the array is required, the circuit includes at least one conducting termination cooperating with a second-type connection block leading to the modular structure external to the array.

6. Connection device according to claim 5, wherein the second-type connection block is configured to be inserted into an opening in the cap.

7. Connection device according to claim 2, wherein the cap protects the signal distribution circuit against electromagnetic interference.

8. Connection device according to claim 1, wherein the terminal connection blocks are configured to be fastened to the plate.

9. Connection device according to claim 5, wherein the second-type connection block can be fastened to the cap.

10. Connection device according to claim 1, wherein the openings in the plate and the terminal connection blocks are provided with polarization means.

11. Connection device according to claim 5, wherein the opening in the cap and the second-type connection block are provided with polarization means.

12. Rack configured to contain an array of electronic-card-carrying modular structures having faces among which one of said faces serves as a back, this rack being configured to cooperate with a connection device according to claim 1, wherein the back houses the plate of the connection device.

13. Rack according to claim 2, wherein said rack includes, on at least one of said faces thereof, on an outside thereof, at least one assembly region recessed with respect to said one of said faces, this region being configured to accommodate assembly means when joining said rack to another rack, the assembly means remaining set back or flush with the face after the assembly operation.

14. Rack according to claim 12, wherein one or more of said faces of said rack are provided with at least one orifice for cooling the modular structures.

15. Rack according to claim 12, wherein said rack comprises at least one stiffening partition defining at least two housings for the modular structures.
