Abstract

A preferred embodiment of a modular jack includes a visual indicator for indicating a condition of an electrical signal, and a body capable of receiving at least a portion of a connector plug. The body has a first outer surface located in a first plane, and a second outer surface located in a second plane substantially perpendicular to the first plane. The body defines a pocket for receiving at least a portion of the visual indicator. The pocket extends into the body from the first and the second outer surfaces so that the at least a portion of the visual indicator can be inserted into the pocket in a first direction substantially perpendicular to the first plane, and in a second direction substantially perpendicular to the second plane.

9. The modular jack of claim 3, wherein the first outer surface is an outer surface of a front wall of the body, and the second outer surface is an outer surface of a bottom wall of the body.

10. The modular jack of claim 4, wherein the outboard and inboard inner surfaces are substantially perpendicular, and the upper and rear inner surfaces are substantially perpendicular to the outboard and inboard inner surfaces.

11. The modular jack of claim 4, wherein the at least a portion of the visual indicator is retained in the pocket by an adhesive bond between a surface of the visual indicator and at least one of the outboard, inboard, rear, and upper inner surfaces.

12. The modular jack of claim 4, wherein the visual indicator comprises an LED, and the outboard and inboard inner surfaces are spaced apart by a distance approximately equal to a width of the LED.

13. The modular jack of claim 12, wherein the visual indicator further comprises a terminal electrically coupled to and extending downward from the LED.

14. The modular jack of claim 12, wherein the outboard inboard, and upper inner surfaces each have a length approximately equal to a length of the LED, the outboard, inboard, and rear inner surfaces each have a height approximately equal to a height of the LED, and the rear inner surface has a width approximately equal to a width of the LED.

15. The modular jack of claim 5, wherein the first and second lips are formed respectively on the first and second inner surfaces.
