Abstract

A dual orientation connector having a connector tab with first and second major opposing sides and a plurality of electrical contacts carried by the connector tab. The plurality of contacts includes a first set of external contacts formed at the first major side and a second set of external contacts formed at the second major side. The first plurality of contacts are symmetrically spaced with the second plurality of contacts and the connector tab is shaped to have 180 degree symmetry so that it can be inserted and operatively coupled to a corresponding receptacle connector in either of two insertion orientations.

First claim

What is claimed is:

1. A method of manufacturing a plug connector, the method comprising:
providing a printed circuit board having a plurality of contact pads at a first end and a plurality of solder pads at a second end opposing the first end;
attaching a plurality of contacts to corresponding contact pads;
inserting the printed circuit board and attached plurality of contacts into a metal frame having an opening and aligning the plurality of contacts with the opening;
overmolding a dielectric layer around the contacts within the opening of the metal frame leaving an outer surface of each contact in the plurality of contacts exposed;
soldering a plurality of wires to the plurality of solder pads;
attaching a metal shield to the metal frame, the metal shield forming an enclosure around the solder pads;
filling the enclosure with a dielectric material; and
adhering an outer dielectric shell to the metal shield.

2. The method of manufacturing a plug connector set forth in claim 1 wherein the overmold step comprises an injection molding process using polyoxymethylene (POM).

3. The method of manufacturing a plug connector set forth in claim 1 wherein the dielectric material used in the step of filling the enclosure comprises an elastomer material.

4. The method of manufacturing a plug connector set forth in claim 1 wherein the dielectric material used in the step of filling the enclosure comprises a polyproplylene material.

5. The method of manufacturing a plug connector set forth in claim 1 wherein the outer dielectric shell comprises acrylonitrile butadiene styrene (ABS).

6. The method of manufacturing a plug connector set forth in claim 1 wherein the metal frame comprises a ground ring that includes a tab portion, a base portion and a face that extends between the tab portion and the base portion.

7. The method of manufacturing a plug connector set forth in claim 6 further comprising sliding a dielectric trim piece over the tab portion of the ground ring and attaching the dielectric trim piece to the face of the ground ring.

8. The method of manufacturing a plug connector set forth in claim 1 wherein the plug connector is part of a charging cable.

9. The method of manufacturing a plug connector set forth in claim 1 wherein the plurality of wires are part of a cable bundle and the method further comprising attaching a cable crimp having a metal shield to the cable bundle prior to soldering the plurality of wires to the solder pads.

10. A method of manufacturing a plug connector, the method comprising:
providing a first printed circuit board having a first plurality of contact pads at a first end and a first plurality of solder pads at a second end opposing the first end;
providing a second printed circuit board having a second plurality of contact pads at a first end;
attaching a first plurality of contacts to the first plurality of contact pads;
attaching a second plurality of contacts to the second plurality of contact pads;
inserting the first and second printed circuit boards into a metal frame having a first opening on a first side of the frame and a second opening on a second side of the frame opposite the first side, and aligning the first plurality of contacts with the first opening and aligning the second plurality of contacts with the second opening;
overmolding a dielectric layer around each of the first and second plurality of contacts within the first and second openings of the metal frame leaving an outer surface of each contact in the first and second pluralities of contacts exposed;
soldering a first plurality of wires to the first plurality of solder pads;
attaching a metal shield to the metal frame, the metal shield forming an enclosure around the first plurality of solder pads;
filling the enclosure with a dielectric material; and
adhering an outer dielectric shell to the metal shield.

11. The method of manufacturing a plug connector set forth in claim 10 wherein the metal frame comprises a ground ring that includes a tab portion, a base portion and a face that extends substantially vertically between the tab portion and the base portion.

12. The method of manufacturing a plug connector set forth in claim 10 wherein the second printed circuit board further includes a second plurality of solder pads at a second end opposing the first end and the method further comprises soldering a second plurality of wires to the second plurality of solder pads.

13. The method of manufacturing a plug connector set forth in claim 10 further comprising attaching a metal ground plate between the first and second printed circuit boards.

14. The method of manufacturing a plug connector set forth in claim 10 wherein the overmold step comprises an injection molding process using polyoxymethylene (POM).

15. The method of manufacturing a plug connector set forth in claim 10 wherein the dielectric material used in the step of filling the enclosure comprises an elastomer material.

16. The method of manufacturing a plug connector set forth in claim 10 wherein the dielectric material used in the step of filling the enclosure comprises a polyproplylene material.

17. The method of manufacturing a plug connector set forth in claim 10 wherein the outer dielectric shell comprises acrylonitrile butadiene styrene (ABS).

18. The method of manufacturing a plug connector set forth in claim 10 wherein the plug connector is part of a charging cable.

19. The method of manufacturing a plug connector set forth in claim 10 wherein the plurality of wires are part of a cable bundle and the method further comprising attaching a cable crimp having a metal shield to the cable bundle prior to soldering the plurality of wires to the solder pads.

20. The method of manufacturing a plug connector set forth in claim 19 wherein the step of filling the enclosure with a dielectric material forms a generally circular end portion that surrounds a portion of the cable bundle and a block portion the completes and fills gaps in the metal enclosure.
