Patent ID: 6997720

Claim:
An interconnecting module for the base of an electronic device casing including two groups of printed circuit boards bearing electronic device components, each group having one or more stacked printed circuit boards, and that has a back equipped with a field of contacts constituting electrical connection points accessible from the exterior of the casing, said interconnecting module providing for the transfer, at the level of the two groups of printed circuit boards, of the connection points of the casing accessible from the exterior, comprising a field of electrical connection points transferred to the interior of the casing so as to be facing the two groups of printed circuit boards and tracks setting up the electrical links between this transferred field of connection points and the field of contacts with which the back of the casing is equipped, comprising: a central panel in printed circuit form, fixed to the back of the field of contacts of the connection points of the casing with the external environment, parallel to the back of the casing, and supporting the electrical connection tracks, on a portion of their paths starting from the contacts of this field of connection points with the external environment, said tracks being divided, on this portion of their paths, into at least two groups going towards opposite edges of the central panel, called longitudinal edges, and two side panels in printed circuit form, folded and placed flat against each other between the two groups of printed circuit boards, attached on either side of the central panel, each by an edge of one of the longitudinal edges of the central panel, by means of a linking part in the form of a flexible printed circuit having a size sufficient to enable them to be folded and placed flat against each other, sharing the transferred field of connection points and the linking tracks that lead thereto from the field of contacts of the connection points of the casing with the external environment, the transferred field of connection points being equipped with through-contacts, the connection points of the part of the transferred field borne by a side panel being shifted laterally with respect to the connection points of the matching part of the transferred field borne by the other side panel, the side panels supporting the connection tracks on the portion of their paths that leads to their part of the transferred field of connection points and being provided with at least one aperture leaving space for the through-contacts of the other side panel, the connecting tracks that lead to the part of the transferred field of connection points of a side panel passing, in order to meet contacts of the field of connection points accessible from the exterior of the casing, through the linking part attaching one of the edges of the side panel considered with one of the longitudinal edges of the central panel.
