Electronic card and aircraft including same
View Patent ↗An electronic card that includes at least two superimposed conducting layers with an insulation layer between the two conducting layers, the two conducting layers each including a utility conducting portion and a conducting portion at the periphery of the utility conducting portion with an insulating portion between the conducting portions, the insulating portion of a first of the two layers being offset relative to the insulating portion of the second of the layers. An aircraft includes a housing in which at least one such card is provided.
1. An electronic card comprising:
at least first and second superposed conductive layers with an electrically insulating layer between the first and second conductive layers, the first and second conductive layers each including a useful conductive portion and a conductive portion situated at the periphery of the useful conductive portion, and an electrically insulating portion between the conductive portions,
wherein the insulating portion of the first conductive layer is offset relative to the insulating portion of the second conductive layer, such that part of the useful conductive portion of the first conductive layer is situated in vertical alignment with part of the insulating portion of the second conductive layer, and
wherein part of the peripheral portion of the second conductive layer is situated in vertical alignment with part of the insulating portion of the first conductive layer.
2. A card according to claim 1 , wherein the insulating portions of the first and second conductive layer have the same dimensions.
3. A card according to claim 1 , wherein the offset is substantially equal to the distance separating the conductive portions of the same layer.
4. A card according to claim 1 , comprising at least three conductive layers, whose insulating portions are offset alternatively in one direction then in the opposite direction from one layer to the other.
5. A card according to claim 1 , wherein the insulating portions are made of epoxy.
6. A card according to claim 1 , wherein the insulating layers are made of insulating material based on glass fibers.
7. A card according to claim 1 , wherein the width of an insulating portion is greater than the thickness of an insulating layer.
8. A card according to claim 7 , wherein the ratio between the width of an insulating portion and the thickness of an insulating layer is greater than five.
9. A card according to claim 1 , wherein, for each conductive layer, the useful portion is adapted to be connected electrically to electronic components.
10. An aircraft comprising a compartment including at least one card according to claim 1 .
11. An aircraft according to claim 10 , wherein the compartment is an impermeable compartment.
12. An aircraft according to claim 10 , wherein at least one peripheral portion of each electronic card in the compartment is connected electrically to the frame of the aircraft.
