Patent ID: 8152567

Claim:
A modular jack connector comprising: an insulative housing defining a receiving cavity; a contact module received in the receiving cavity of the insulative housing, said contact module comprising: a paddle board having opposite first and second conductive layers and an insulative layer sandwiched between the first and second conductive layers, said first conductive layer being formed with at least one conductive section, said paddle board defining a plurality of vias extending therethrough; and at least one transformer comprising a magnetic core embedded in the paddle board, and a plurality of PCB layout traces distributed in the paddle board and comprising a first group of PCB layout traces having one group of tips extending to a position adjacent to corresponding magnetic core to form a magnetic field and another group of tips connected to the conductive section, and a second group of PCB layout traces having one group of tips extending to a position adjacent to corresponding magnetic core to form a magnetic field and another group of tips connected to the vias; at least one common mode choke surface mounted on the conductive section; a plurality of contact terminals attached to the second conductive layer of the paddle board; and a converting module secured to the first conductive layer of the paddle board and having a plurality of converting terminals inserting through said vias.
