PURPOSE: A high performance connector having a cross-talk suppressing function is provided to remove a difference of an interference energy on a circuit by appending an insertion circuit for generating an artificial capacity connection between an interference source conducting wire and an interfered conducting wire, thereby inducing the interference energy from the interference source conducting wire to the interfered conducting wire. CONSTITUTION: More than one pair cables are connected at the upper and lower sides of a PCB(1) having an electric circuit. Leads(11-18) of a modular jack(2) constituting a pair is connected to conducting wires(21-28) on a PCB(1), and the conducting wires(21-28) are connected to a connecting block pin(31-38) for connecting to a cable. An insertion circuit for removing a cross-talk between the pairs comprises conducting wires(41-45) being arrayed to each conducting wire(21-28) in parallel and one conducting wire(46-48) for connecting the conducting wires(21-28, 41-45). An electric circuit is constructed on the PCB(1) by using conducting wires(24,25) of a pair1(P1), conducting wires(21,22) of a pair2(P2), conducting wires(23,26) of a pair3(P3) and conducting wires(27,28) of a pair4(P4). An interval, a size and a material are constructed on the PCB(1) for having wanted characteristic impedance, a cross-talk characteristic, a damping and an electric wave characteristic. |
