Abstract: An electrical connector includes a connector part (10) with a conductive shell (12) and front and rear contacts (26, 56, 58, 59) at the front and rear of the shell, wherein a transformer (40) with first and second windings lies within the shell and is connected to the front and rear contacts to provide impedance transformation and DC isolation. An entire connector assembly (100) includes a termination assembly (101) lying rearward of the connector part, the termination assembly including a cable clamp (102) for holding a cable (104), the rear of the termination assembly having slots for holding cable wires (110, 112, 113) after they have been bent at least about 90°. The rear contacts of the connector part are in the form of insulation displacement contacts which cut into the wires as the connector part is moved rearwardly against the front of the termination assembly, to thereby connect the front contacts of the connector part to the cable wires.
