an indicating assembly mounted to the substrate and comprising a second printed circuit board, a plurality of light emitting diodes (LEDs) assembled on the second printed circuit board, and a plurality of L-shaped terminals mounted into the L-shaped slots of the substrate and electrically connecting the second printed circuit board to the mother printed circuit board; and

a plurality of indicating pipes received within the channels and positioned in alignment with the LEDs; and

an outer shield enclosing the insulative housing.

2. The electrical connector as claimed in claim 1 , wherein said substrate has a plurality of protrusions extending into the L-shaped slots for interfering with the L-shaped terminals.

3. The electrical connector as claimed in claim 1 , wherein said second printed circuit board is assembled to a front portion of the substrate and has a plurality of vias for electrically connecting with the L-shaped terminals.

4. The electrical connector as claimed in claim 3 , wherein each L-shaped terminal has a first contacting end extending through a hole defined on the second circuit board and a second contacting end extending downwardly beyond the substrate for electrically connecting with the mother printed circuit board.

5. The electrical connector as claimed in claim 1 , wherein said substrate has a plurality of posts extending forwardly, and the insulative housing has a plurality of recesses mating with the posts.

6. The electrical connector as claimed in claim 1 , wherein said insulative housing has a projecting portion extending rearwardly therefrom, and said substrate has a protruding portion coupling with the projecting portion.

7. The electrical connector as claimed in claim 1 , wherein the insulative housing comprises two rows of ports for mating with a plurality of electrical plugs.

8. The electrical connector as claimed in claim 1 , further comprising a plurality of daughter printed circuit boards mounted to the insulative housing, and wherein there are a plurality of substrates each positioned parallel to an adjacent daughter printed circuit board in an alternating relationship.

9. The electrical connector as claimed in claim 8 , further comprising a plurality of contacting modules each positioned into an aperture formed on a front portion of a respective one of the daughter printed circuit boards and mounted into the port.

10. The electrical connector as claimed in claim 8 , further comprising a connecting module assembled to a bottom portion of the daughter printed circuit board and connected to the mother printed circuit board.

11. The electrical connector as claimed in claim 10 , wherein said connecting module comprises a passageway defined on a side portion thereof, and said substrate has a protruding portion on a bottom edge thereof for coupling with the second passageway.

12. An electrical connector comprising:

an insulative housing;

a plurality of terminal modules assembled to the housing for mounting to a mother board; and

a plurality of indicating modules alternately arranged with the terminal modules, each of said indicating modules including a first substrate defining a plurality of slots receiving therein a plurality of terminals for connecting to the mother board, and a second substrate positioned in front of and perpendicular to the first substrate and connected to the terminals; wherein

said second substrate is a printed circuit board and a plurality of LEDs are linked thereto under condition of said LEDs being exposed to a front face of the housing.
