Abstract

An electronic equipment item for an electronic system, comprising a housing, a backplane board, at least one daughterboard and at least one lightning protection board housed in the housing. A connector is fixed to the backplane board and configured to be connected to the rest of the electronic system. For each daughterboard there is provided one lightning protection board. For each lightning protection board, a first port is arranged to connect the lightning protection board to the backplane board, and a second port is arranged to connect the daughterboard to the lightning protection board.

First claim

1 . An electronic equipment item for an electronic system, the electronic equipment item comprising:
a housing, a backplane board housed in the housing, a connector fixed to the backplane board and configured to be connected to a rest of the electronic system, at least one daughterboard housed in the housing, and for each daughterboard, a lightning protection board housed in the housing, wherein, for each lightning protection board, a first port is arranged to connect the lightning protection board to the backplane board, and a second port is arranged to connect the daughterboard to the lightning protection board.

2 . The electronic equipment item according to claim 1 , wherein the first port and the second port have perpendicular directions of fitting.

3 . The electronic equipment item according to claim 2 , wherein the second port is of the type with a fitting perpendicular to the lightning protection board.

4 . The electronic equipment item according to claim 1 , further comprising, for each pair of a lightning protection board and a daughterboard, an independent housing in which the lightning protection board and the daughterboard are fixed.

5 . An aircraft comprising an electronic system having at least one electronic equipment item according claim 1 .

6 . An electronic equipment item for an electronic system, the electronic equipment item comprising:
a housing, a backplane board housed in the housing, a connector fixed to the backplane board and configured to be connected to a rest of the electronic system, at least one daughterboard housed in the housing, and for each daughterboard, a lightning protection board housed in the housing, wherein, for each lightning protection board, a first port is arranged to connect the lightning protection board to the backplane board, and a second port is arranged to connect the daughterboard to the lightning protection board, the daughterboard being connected to the backplane board only through the second port.

7 . The electronic equipment item according to claim 6 , wherein the first port comprises a fitting between the backplane board and the lightning board in which the backplane board and the lightning board are connected by a displacement of the lightning board in a direction perpendicular to a large surface of the backplane board and the second port comprises a fitting between the lightning protection board and the daughterboard in which the lightening board and the daughterboard are connected by a displacement of the daughterboard in a direction perpendicular to a large surface of the lightening protection board.

8 . The electronic equipment item according to claim 7 , wherein the large surface of the lightning protection board is perpendicular to the large surface of the backplane board.

9 . The electronic equipment item according to claim 6 , further comprising, for each pair of a lightning protection board and a daughterboard, an independent housing in which the lightning protection board and the daughterboard are fixed.

10 . The electronic equipment item according to claim 6 , wherein the independent housing comprises a window therein to accommodate the connection of the lightning protection board to the backplane board.
