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

The invention claimed is:

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.
