1. An electrical connector assembly for mounting on a mother board, comprising:
- a bracket defining an upper cavity and a lower cavity;
a first connector received in the upper cavity and including a first insulative housing, the first insulative housing including a receiving cavity and a terminal module accommodated in the receiving cavity, the terminal module including an insulative holder and a plurality of terminals retained in the holder, each terminal forming a rearwardly extending mounting tail;
a second connector received in the lower cavity and including a second insulative housing and a plurality of contacts retained in the second insulative housing;
a circuit board disposed at a rear of the bracket and including circuit traces on at least one side thereof and a plurality of holes, the circuit traces connecting to the holes, the holes receiving the mounting tails, the circuit traces being so arranged that one of a pair the of circuit traces is arranged on one side of the circuit board while another of the pair of circuit traces is arranged on another side of the circuit board, the pair of circuit traces being the mirror-image of each other whereby a magnetic and electrical field generated by one circuit trace neutralizes a magnetic and electrical field generated by the other of the pair, thus reducing cross talk therebetween; and
an intermediate device connected between the circuit traces of the circuit board and the mother board;
wherein the electrical connector further comprises an indicating device retained in the first insulative housing, the indicating device including a first insulative body, a light emitting device, and a pair of conductive wires connected to the light emitting device, the wires extending beyond the first insulative body and being connected to the circuit traces of the circuit board, the first insulative housing including a retention groove in a top surface thereof for retaining the indicating device therein, a cutout proximate the retention groove and a vertical groove at a rear of the retention groove, wherein the first insulative body of the indicating device includes a laterally extending block for engaging with the cutout and a downwardly extending post for engaging with the vertical groove thereby securing the indicating device to the first insulative housing.

Abstract
An electrical connector assembly comprises a first connector, a pair of second connectors, a circuit board and a bracket. The first connector includes a plurality of terminals having mounting tails. A pair of indicating devices mounted to the first connector each has conductive wires extending therefrom. Circuit traces are longitudinally arranged on the circuit board. First ends of the circuit traces are connected to the mounting tails while second ends of the circuit traces are connected to an intermediate device connected to a mother board. The circuit traces are arranged so that cross talk therebetween can be effectively reduced.
