Structure for connecting flexible flat cables
A trunk cable 12 includes a signal trunk conductor 31 that is electromagnetically shielded by a shield layer 35 . A branch cable 13 includes a signal branch conductor 38 that is electromagnetically shielded by a shield layer 42 . The signal trunk conductor 31 and the signal branch conductor 38 are electrically connected to each other by a relay bus bar 64 that is electromagnetically shielded by a base shielding member 65 and a cover shielding member 27.
1. A structure for connecting flexible flat cables, comprising:
a flexible flat trunk cable that includes a signal trunk conductor, a ground trunk conductor, a trunk shield that is electrically connected to the ground trunk conductor and encloses the signal trunk conductor to electromagnetically shield the signal trunk conductor, and an insulating trunk coating for covering the signal trunk conductor, the ground trunk conductor, and the trunk shield;
a flexible flat branch cable that includes a signal branch conductor, a ground branch conductor, a branch shield that is electrically connected to the ground branch conductor and encloses the signal branch conductor to electromagnetically shield the signal branch conductor, and an insulating branch coating for covering the signal branch conductor, the ground branch conductor, and the branch shield;
a relay bus bar that includes a trunk-side terminal portion connected to the signal trunk conductor, and a branch-side terminal portion connected to the signal branch conductor; and
a shielding member for enclosing the relay bus bar to electromagnetically shield the relay bus bar; the shielding member includes a trunk-side ground terminal portion connected to the ground trunk conductor, and a branch-side ground terminal portion connected to the ground branch conductor; the shielding member includes a base shielding member that includes the trunk wherein side ground terminal portion and the branch-side ground terminal portion, and a cover shielding member for enclosing the relay bus bar between the base shielding member and the cover shielding member; and wherein an insulating cover made of an insulating synthetic resin is interposed between the relay bus bar and the cover shielding member.
2. The structure for connecting flexible flat cables according to claim 1 ,
wherein the base shielding member and the cover shielding member are electrically connected to each other.
