A method for integrating an avionic cabling assembly interconnection module (6; 6a, 6b) in an electronic cabinet for housing and connecting electronic modules comprising a front face, a back panel having an internal face provided with a card for connection to said electronic modules and two lateral walls (15, 16) having external faces (15a, 16a), characterized in that it consists of: - moving, parallel with a lateral wall (15, 16) of the cabinet, at least one interconnection module (6; 6a, 6b) comprising connectors (60; 60a to 60c), towards said assemblies on a principal external face and a connection circuit (C6a, C6b) on a lateral face (62a, 62b); - inserting said interconnection module (6; 6a, 6b) perpendicularly to said lateral wall (15, 16) in a lateral housing space (E1, E2) limited by the external face (15a, 16a) of said lateral wall (15, 16) and edges (14a, 14b; 11a, 11b) respectively extending the back panel and the front face; - mechanically connecting the ends (81, 82) of a handle mounted, such that it pivots vertically on said module (6; 6a, 6b), on fixed points (10a, 10b; E10) on the external face (15a, 16a) of said lateral wall (15, 16); - pivoting (R3, R4) the handle (8a, 8b) in such a way that said handle ends (81, 82) rotate about fixed points (10a, 10b; E10) in order to move said module (6a, 6b) in translation (T3, T4) along the external face (15a, 16a) of the lateral wall (15, 16) and that connection circuits (C6a, C6b), arranged on a lateral face (62a, 62b) of said interconnection module (6a, 6b) in liaison with the connectors (60; 60a to 60c) of said principal external face and with connectors (C1a, C1b) arranged on the internal face (140a, 140b) of said edge (14a, 14b) of back panel in liaison with the connectors of the electronic modules of the back panel, become closed one upon the other so that it is possible to couple the cabling assemblies with the electronic modules, and - locking said module (6; 6a, 6b) in the closed position by reversible mechanical clamping between said lateral wall (15, 16) and said interconnection module (6; 6a, 6b). - moving, parallel with a lateral wall (15, 16) of the cabinet, at least one interconnection module (6; 6a, 6b) comprising connectors (60; 60a to 60c), towards said assemblies on a principal external face and a connection circuit (C6a, C6b) on a lateral face (62a, 62b); - inserting said interconnection module (6; 6a, 6b) perpendicularly to said lateral wall (15, 16) in a lateral housing space (E1, E2) limited by the external face (15a, 16a) of said lateral wall (15, 16) and edges (14a, 14b; 11a, 11b) respectively extending the back panel and the front face; - mechanically connecting the ends (81, 82) of a handle mounted, such that it pivots vertically on said module (6; 6a, 6b), on fixed points (10a, 10b; E10) on the external face (15a, 16a) of said lateral wall (15, 16); - pivoting (R3, R4) the handle (8a, 8b) in such a way that said handle ends (81, 82) rotate about fixed points (10a, 10b; E10) in order to move said module (6a, 6b) in translation (T3, T4) along the external face (15a, 16a) of the lateral wall (15, 16) and that connection circuits (C6a, C6b), arranged on a lateral face (62a, 62b) of said interconnection module (6a, 6b) in liaison with the connectors (60; 60a to 60c) of said principal external face and with connectors (C1a, C1b) arranged on the internal face (140a, 140b) of said edge (14a, 14b) of back panel in liaison with the connectors of the electronic modules of the back panel, become closed one upon the other so that it is possible to couple the cabling assemblies with the electronic modules, and - locking said module (6; 6a, 6b) in the closed position by reversible mechanical clamping between said lateral wall (15, 16) and said interconnection module (6; 6a, 6b).
