Abstract

Disclosed is a connector comprising a front retaining member with a pin receiving passageway, a plurality of conductive pins extending through the passageway, a rear retaining means with a plurality a pin receiving means and a printed wiring board with capacitors and central apertures and being interposed between the front and rear retaining members so as to receive the pins in said apertures.

Claims

1. An electrical connector comprising:

(a) a front retaining means comprising a conductive shell having a peripheral flange and a pin receiving passageway;

(b) a plurality of conductive pins extending through the passageway of the front retaining means;

(c) a concave insulative rear retaining means having a plurality of apertures through which the conductive pins pass; and

(d) a capacitive means comprising a printed wiring board having a plurality of central apertures and being interposed between said front retaining means and rear retaining means so as to receive the pins in said apertures, and said board having a component side oriented toward the rear retaining means, and a reverse side oriented toward the front retaining means and fixed to the peripheral flange thereof and a peripheral edge, and on the component side of said board there is a conductive strip adjacent the peripheral edge on said component side, and outwardly adjacent at least some of the central apertures there are conductive bands and a capacitor is positioned between at least some of said conductive bands and the conductive strip adjacent the peripheral edge, and on the reverse side of said board a non-conductive area surrounds at least some of the central apertures and said non-conductive areas are surrounded by conductive areas; and

(e) a ferrite element filter means positioned within the rear insulating member.

2. The connector of claim 1 wherein an additional partial wiring board is positioned between the ferrite element and the rear retaining means.

3. The connector of claim 1 wherein outwardly adjacent each of the central apertures there is a concentric metalized band having an outer circular edge.

4. The connector of claim 3 wherein a capacitor is positioned between each of the metalized bands and the metalized strip adjacent the edge.

5. The connector of claim 4 wherein a metalized extension connects each of the capacitors with the metalized strip.

6. The connector of claim 5 wherein a metalized extension connects each of said capacitors with one of said metalized bands surrounding one of said central apertures.

7. The connector of claim 6 wherein on the reverse side of the printed wiring board adjacent each of the central apertures there is a narrow metalized band.

8. The connector of claim 7 wherein on the reverse side of the printed wiring board a non-metalized area extends concentrically from each of each of said metalized bands and said non-metalized area has an outer circular edge.

9. The connector of claim 8 wherein on the component side of the printed wiring board each of the outer circular edges of the metalized boards has a diameter which is generally uniform with the diameters of each of the other diameters of said outer circular edges of the metalized bands and on the reverse side of the printed wiring board each of the outer circular edges of the non-metalized areas has a diameter which is generally uniform with the diameters of each of the other diameters of each of the other outer diameters of said outer circular edges of non-metalized areas and the diameters of the outer circular edges of the non-metalized areas are less than the diameters of the outer edges of the metalized bands.

10. The connector of claim 9 wherein outside of the edges of the non-metalized bands the rear side of the printed wiring board is completely metalized.

11. The connector of claim 10 wherein the pins are soldered to the metalized bands on the component side of the printed wiring board.

12. The connector of claim 11 wherein the pins are soldered to the metalized bands on the reverse side of the printed wiring board.

13. The connector of claim 1 wherein the front conductive shell has a peripheral flange.

14. The connector of claim 1 wherein a filter means is positioned within the rear insulating member.

15. The connector of claim 14 wherein the filter means is a ferrite element.

16. The connector of claim 15 wherein the ferrite element has a plurality of bores through which the conductive pins pass.

17. The connector of claim 16 wherein a second printed wiring board is positioned between the ferrite element and the rear wall of the insulating element.

18. The connector of claim 17 wherein the second printed wiring board has a plurality of apertures through which the conductive pins pass.

19. The connector of claim 18 wherein cushioning means are positioned adjacent the ferrite element.

20. The connector of claim 19 wherein the cushioning means are plastic wafers.

21. The connector of claim 1 wherein the rear retaining member is conductive.

22. The connector of claim 1 wherein integral fastening means extend from the conductive shell.

23. The connector of claim 2 wherein the integral fastening means are conductive to effect grounding of the capacitive means.

24. The connector of claim 1 wherein the rear retaining means is held in position by means of frictional force between the rear retaining means and the conductive pins.
