Abstract

An electrical connector includes: an insulative housing; and an inserting module positioned in the insulative housing and including a transformer, the transformer comprising: a magnetic core having a central opening; and a first and second wire groups each including plural wires, each wire having a central portion, a first end, and an opposite second end, the central portions of each wire group wound around the magnetic core through the central opening, wherein the first and second wire groups joint to function as a primary winding and a secondary winding of the transformer, and a wire diameter of the secondary winding is greater than a wire diameter of the primary winding.

First claim

What is claimed is:

1. An electrical connector comprising:
an insulative housing; and
an inserting module positioned in the insulative housing and including a transformer, the transformer comprising:
a toroidal magnetic core having a central opening; and
a first and second wire groups each including plural wires, each wire having a central portion, a first end, and an opposite second end, the central portions of each wire group wound around the magnetic core through the central opening; wherein

the first and second wire groups joint to function as a primary winding and a secondary winding of the transformer, and a wire diameter of each of the plural wires of the secondary winding is greater than a wire diameter of each of the plural wires of the primary winding.

2. The electrical connector as claimed in claim 1 , wherein the first and second ends of the first and second wire groups are respectively twisted as input ends, output ends, and center taps of the transformer.

3. The electrical connector as claimed in claim 1 , wherein the magnetic core includes a left half and a right half, the central portion of the first wire group only wound around the left half, the central portion of the second wire group only wound around the right half.

4. The electrical connector as claimed in claim 1 , wherein the center tap of the secondary winding is electrically connected to corresponding a circuit derived from a power sourcing equipment (PSE).

5. The electrical connector as claimed in claim 4 , wherein the printed circuit board is divided into opposite cable side and physical side, and the secondary winding is closer to the cable side while the primary winding is closer to the physical side.
