This present invention refers to a combined terminal and casing for establishing electrical contact between a multi-wire cable and a magnetic wire that uses the insulation displacement connector (IDC) concept, wherein the terminal (11, 25) has holes (12, 26) and closed channels (13, 27) to receive the multi-wire cable (23, 36) and openings (14, 28) to receive the magnetic wire (24, 37) linked to narrow slots (15, 29). The casing (18, 31) has through-holes (20, 21, 32, 34) for inserting the multi-wire cable (23, 36) and the magnetic wire (24, 37), as well as an opening (19, 35) to receive the terminal. Inserting the terminal into the casing causes the pressure exerted on the multi-wire cable and the magnetic wire to force the entry thereof into the narrow channels, causing the isolation layer to be withdrawn, providing electrical contact between the multi-wire cable and the terminal, between the magnetic wire and the terminal and, consequently, between the multi-wire cable and the magnetic wire.
