Abstract:
1. A high-frequency signal double-layer flat cable adapter card, particularly a double-layer flat cable adapter card that is capable of eliminating transmission disorder of a double-layer cable caused by paralleling and overlapping of high-frequency signals and a DC supply loop, comprising a first connecting end, including a first substrate and a connector; said first substrate has a first connecting pin and a second connecting pin set on its front and rear sides respectively; a second connecting end, including a second substrate with a third connecting pin and a fourth connecting pin set on its front and rear sides respectively; and a flat cable group including a minimum of two flat cables arranged as upper-lower double layer and connected between said first and second connecting ends, said first flat cable, as the upper layer, has its front and back ends electrically connected to the first connecting pin of said first substrate and the third connecting pin of said second substrate respectively, and the second flat cable, as the lower layer, has its front and back ends electrically connected to the second connecting pin of said first substrate and the fourth connecting pin of said second substrate respectively; wherein said flat cable group has a fine conductive metal foil sheet arranged between the upper and lower flat cables with a width covering areas of said flat cable group adopted as a power supply loop to isolate the magnetic field effect in the areas of said upper and lower flat cables adopted as a power supply loop; and a conductive adhesive tape with high frequency shielding effects wraps the entire double-layer flat cable group to minimize the loss of high frequency signals.
