Abstract

A stacked electrical connector 2 including right angle RJ-45 modular jacks 4 positioned in columns also includes LED'"'"'s 38 positioned on the front mating face 18 of the connector 2. Internal passages 28 extend from the mating face 18 of the jack housing 18 and intersect channels 34 extending to the bottom pcb mounting face 22 where the connector 2 and jacks 4 are soldered to a printed circuit board. LED leads 42 are located in the passages 28 and contacts 44 are located in channels 34. Insulation displacement slots 48 at the top of the contacts 44 terminate the leads 42. The termination points are staggered and the leads 42 in a column are of different lengths so that contacts 44 of different lengths can engage corresponding leads 42. LED'"'"'s 38 can thus be positioned beside mating openings 20 on the front of the connector 2 to provide status indications.

Claims

1. An electrical connector which is matable with a compatible connector, the electrical connector comprising:

a plurality of terminals positioned in a nonconductive housing, the housing having a mating face configured to mate with the compatible connector, an indicator located on the mating face, a passage extending rearwardly from the mating face, indicator leads extending from the indicator through the passage, the housing having a mounting face and channel means which open through the mounting face, the channel means extending in a direction transverse to the passage and intersecting the passage, contacts positioned in the channel means and extending to the mounting face, each of the contacts being electrically terminated to one of the indicator leads, each of the contacts having a split beam contact section including a slot which is open in the transverse direction whereby, during insertion of the contacts into the channel means in the transverse direction, the indicator leads which are disposed in the passage are received in the slots of the split beam contact sections and are electrically terminated to the contacts.

2. The electrical connector of claim 1 wherein the mating face extends at a right angle relative to the mounting face with the internal passage extending parallel to the mounting face and the channel means extending parallel to the mating face.

3. The electrical connector of claim 1 wherein the indicator comprises a light emitting diode.

4. The electrical connector of claim 1 wherein a plurality of said indicators are positioned in a column on the mating face.

5. The electrical connector of claim 4 wherein the length of the indicator leads is progressively less for leads closer to the housing mating face.

6. A stacked electrical connector comprising;

multiple female electrical connectors located in a nonconductive housing, each said female electrical connector having a mating opening on a mating face of the nonconductive housing for receiving a corresponding male electrical connector therein;

indicators positioned adjacent to respective ones of the mating openings, each of the indicators having leads extending through a respective passage in the nonconductive housing, each said passage penetrating the housing from the mating face;

channel means penetrating the nonconductive housing from a second face of the nonconductive housing and intersecting each said passage; and

contacts located in the channel means and forming an electrical connection with the indicator leads at the intersections of the passages and the channel means, wherein the intersections between the indicator leads and the contacts are staggered, and the contacts extend to the second face of the nonconductive housing for external electrical termination.

7. The stacked electrical connector of claim 6 wherein the contacts have different lengths and the leads have different lengths.

8. The stacked electrical connector of claim 7 wherein longer leads are connected to longer contacts and shorter leads are connected to shorter contacts.

9. The stacked electrical connector of claim 6 wherein the channel means extend upwardly from a mounting face extending perpendicular to the mating face.

10. A printed circuit board jack matable with a plug, the jack comprising:

a plurality of terminals positioned within a nonconductive housing, each said terminal having a mating end located adjacent to a mating face of the housing, the housing including a passage extending from the mating face and a channel intersecting the passage and opening on a printed circuit board face of the housing;

an indicator positioned on the mating face, the indicator having two indicator leads extending through the passage, the leads intersecting the channel, one of the leads being shorter than the other of the leads; and

printed circuit board contacts extending through the channel and contacting the indicator leads at the intersection of the passage and the channel so that the indicator leads can be connected to printed circuit board traces, wherein the contact which is connected to the shorter lead is positioned in front of the contact which is connected to the relatively longer lead.

11. The jack of claim 10 wherein the passage and the channel extend beside the terminals.

12. The jack of claim 11 wherein the terminals are right angle terminals with the passage and the channel intersect at right angles.

13. The jack of claim 12 wherein each indicator includes an anode lead and a cathode lead and the jack includes two contacts for each indicator, a first contact engaging the anode lead and a second contact engaging the cathode lead.

14. The jack of claim 10 wherein each said contact includes a split beam contact section at the top thereof, and the indicator leads are positioned in respective ones of the split beam contact sections.

15. The jack of claim 10 wherein the indicator is a light emitting diode.

16. The jack of claim 10 comprising a multiposition jack having a plurality of separate mating openings on the mating face for receiving multiple plugs, separate indicators being positioned adjacent each mating opening.

17. The jack of claim 10 comprising an RJ-45 jack.

18. The jack of claim 10 wherein a plurality of indicators are positioned on the mating face, one passage extending from the mating face for each indicator with a single channel intersecting passages for multiple indicators.

19. The jack of claim 10 wherein the contact connected to the shorter lead is shorter than the contact connected to the relatively longer lead.

20. The jack of claim 19 comprising a stacked modular jack with at least two jacks being positioned one above the other in the same nonconductive housing, and the indicators adjacent to the jacks are also positioned one above the other.
