Abstract

A modular jack connector (100) includes a contact module (2) having a paddle board (21) and a magnetic module (23). The magnetic module includes a number of magnetic cores (231) embedded in the paddle board, and a number of PCB layout traces (232, 233) arranged in each side face of the paddle board. The PCB layout traces on each side face includes a primary group of PCB layout traces (232a, 233a) having one group of tips (2322, 2331) extending to a position adjacent to corresponding magnetic core to form a magnetic field and another group of tips (2321, 2332) connected to a conductive section (2111, 2121) of the paddle board, and a secondary group of PCB layout traces (232b, 233b) having one group of tips (2323, 2333) extending to a position adjacent to corresponding magnetic core to form a magnetic field and another group of tips (2324, 2334) connected to vias of the paddle board.

Claims

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 side faces and a plurality of vias extending through the first and second side faces, each of the first and second side faces being provided with a conductive section; and

a magnetic module comprising a plurality of magnetic cores embedded in the paddle board, and a plurality of PCB layout traces arranged in each of the first and second side faces of the paddle board, said PCB layout traces on each of the first and second side faces comprising a primary 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 secondary 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;

a plurality of contacts attached to the first side face of the paddle board and soldered on the conductive section of the first side face;

an electronic component attached to the second side face of the paddle board and soldered on the conductive section of the second side face; and

a converting module secured to the second side face of the paddle board and having a plurality of converting terminals inserting through said vias.

2. The modular jack connector as claimed in claim 1, wherein said plurality of magnetic cores comprise a pair of upper magnetic cores disposed adjacent to the conductive sections and a pair of lower magnetic cores disposed adjacent to the vias, and wherein each upper magnetic core and associated PCB layout traces constitute a common mode choke, and wherein each lower magnetic core and associated PCB layout traces constitute a transformer.
