Method and apparatus for terminating wire wound magnetic core

摘要

A modular jack has a magnetic assembly including insulative body, two rows of terminals retained to the insulative body, four transformers, and four common mode chokes. Each of the transformer and common mode choke includes a magnetic core and a plurality of conductive wires wound therearound. Each terminal has a recess for receiving an end portions of a corresponding wire and then the terminal is inserted into a through-hole of an internal printed circuit board for dip soldering. Guiding of the wire to the recess can be automated in contrast to manual winding operation.

1. An electrical connector comprising:
a magnetic assembly having:
an insulative body having a front wall, a rear wall, two oppositely facing side walls between the front wall and the rear wall, and a receiving slot surrounded by said walls;a plurality of contacts each having a first retention portion retained in the front wall and a first connecting portion extending outwardly along the front wall;a plurality of leads each having a second retention section retained in the rear wall and a second connecting portion extending outwardly along the rear wall;a plurality of signal conditioning components each having a magnetic core and a plurality of conductive wires wound around the core, the magnetic cores received within the receiving slot, the conductive wires including a plurality of first distal portions connecting to the first connecting portions and a plurality of second distal portions connecting to the second connecting portions; anda printed circuit board (PCB) defining a plurality of conductive apertures for the first and second connecting portions to insert through; wherein each of the first and second connecting portions defines a recess to receive a corresponding one of the first and second distal portions of the conductive wires, the distal portions of the conductive wires extend across the conductive apertures, and the distal portions are soldered to corresponding connecting portions; the PCB is disposed above the insulative body and disposed horizontally along a front-to-back direction; said first and second connecting portions extend upwardly beyond the PCB, said recess of the connecting portion located on a top thereof; and said recesses of the first and second connecting portions are recessed downwardly.
