Abstract

A modular jack (100) for receiving a mating plug includes a visual indicator (3) having a lighting pipe (31), a pair of pins (32) extending from the lighting pipe and a separate guiding pipe (33), and an insulative housing (1) including a front face (1), an opposite rear face (13), side faces (12) connecting with the front face and rear face. The insulative housing defines a pipe slot (152) extending through the front face and the side face for receiving the guiding pipe, and further has a receiving channel (152) in communication with the pipe slot for receiving the lighting pipe and a number of pin slots (151) extending rearwardly and through the rear face of the housing for receiving the pins.

Claims

1. A modular jack for receiving a mating plug, comprising:

a visual indicator for indicating a condition of an electrical signal, the visual indicator comprising a lighting pipe, a pair of pins extending from the lighting pipe, and a separate guiding pipe;

an insulative housing comprising a front face, an opposite rear face, side faces connecting with the front face and rear face, and a receiving space for engaging with the mating plug, wherein said insulative housing defines a pipe slot extending through the front face and the side face for receiving the holding pipe, a receiving channel in communication with the pipe slot for receiving the lighting pipe, and a plurality of pin slots extending rearwardly and through the rear face of the housing for receiving the pins; and

a terminal module comprising a plurality of terminals received in the receiving space, wherein said insulative housing comprises a second protruding wall extending from the inner surface of the receiving channel into the receiving channel, and wherein the lighting pipe is retained between the second protruding wall and a bottom surface of the receiving channel, further comprising a conductive outer shield enclosing the insulative housing.

2. The modular jack as claimed in claim 1, wherein said insulative housing comprises a first protruding wall extending from the inner surface of the pipe slot into the pipe slot, and wherein the guiding pipe is retained between the first protruding wall and a bottom surface of the pipe slot.

3. The modular jack as claimed in claim 1, wherein said guiding pipe comprises a rib disposed on a top surface thereof and resisting against the second protruding wall.

4. The modular jack as claimed in claim 1, wherein said insulative housing comprises a slantwise section disposed on the bottom surface of the receiving channel for guiding the pins into the corresponding pin slots.

5. The modular jack as claimed in claim 1, wherein said terminal module comprises a printed circuit board, and a plurality of contacts mounted to a rear section of the printed circuit board.

6. An electrical connector comprising:

an insulative housing defining a plug receiving cavity with a plurality of contacts extending thereinto;

a pair of pipe slots formed beside while isolated from said plug receiving cavity;

a pair of receiving channels communicatively aligned with the pair of pipe slots;

a pair of pin slot sets communicatively aligned with the pair of receiving channels;

a pair of pin sets received in the corresponding pair of pin slots sets, respectively;

a pair of lighting pipes integrally formed with the corresponding pair of pin sets and received in the corresponding receiving channels, respectively; and

a pair of guiding pipes discrete from while intimately engaged with the corresponding pair of lighting pipes, respectively, wherein both said receiving channel and the pipe slot extend through the housing sidewall while being covered by a metallic shell.

7. The electrical connector as claimed in claim 6, wherein said receiving channel is smaller than the pipe slot, and the pin slot set is smaller than the receiving channel.
