Abstract

An electrical connection assembly includes a connector and a cable. The connector includes a plug having a multitude of contacts in electrical communication with the cable wires. The connector further includes a body in which a printed circuit board is inserted. The cable wires are soldered to the bonding pads of the printed circuit board which is encapsulated by an adhesive. The connector further includes a metallic shield enclosing the body and providing a path to the ground. An inner mold encapsulates the space enclosed by the metallic shield. The metallic shield is optionally formed from a pair of metallic shields cans that are crimped and laser welded. The assembly further includes a sleeve attached at a rear face of the metallic shield, an enclosure attached to the connector body, and a pair of face plates attached between the enclosure and the body.

Claims

1. A method of forming a connection between a connector and a cable, said connector comprising a body and a plug, said body adapted to receive the cable, said connector adapted to be inserted into a receptacle connector, the method comprising:

inserting a printed circuit board into a cavity formed in the connector plug and body;

attaching a plurality of wires of the cable to a plurality of bonding pads of the printed circuit board to form a plurality of electrical connections;

encapsulating the printed circuit board with an adhesive;

enclosing the body with a metallic shield; and

performing a first insert molding operation to encapsulate a space enclosed by the metallic shield.

2. The method of claim 1 wherein the enclosing of the body with the metallic shield comprises:

crimping first and second said metallic shields around the body; and

welding the first metallic shield to the second metallic shield using a laser beam.

3. The method of claim 2 further comprising:

performing a second insert molding operation to form a sleeve at a rear face of the first and second metallic shields.

4. The method of claim 3 further comprising:

attaching an enclosure to the body.

5. The method of claim 4 further comprising:

bonding first and second face plates between the enclosure and the body using an adhesive.

6. The method of claim 1 further comprising:

dispensing the adhesive on the printed circuit board from one or more nozzles using a high pressure high accuracy jetting action.

7. The method of claim 6 further comprising:

curing the dispensed adhesive using a UV light.

8. The method of claim 1 wherein at least one of the plurality of electrical connections provides a first conductive path to a ground terminal.

9. The method of claim 8 further comprising:

electrically coupling the cable'"'"'s braid, the first and second metallic shields and a metal ground ring defining a shape of the plug to form a second conductive path to the ground terminal.

10. The method of claim 9 further comprising:

coupling a plurality of the cable'"'"'s braid to the cable wires forming the first conductive path to the ground terminal.

11. An electrical connection assembly comprising a connector and a cable, said connector adapted to be inserted into a receptacle connector and comprising:

a plug having a plurality of contacts adapted to receive electrical signals from and supply electrical signals to a plurality of wires in the cable; and

a body comprising;

a printed circuit board including a plurality of bonding pads attached to a plurality of wires of the cable;

a viscous adhesive encapsulating the printed circuit board;

a metallic shield enclosing the body; and

a first mold encapsulating a space enclosed by the metallic shield.

12. The electrical connection assembly of claim 11 wherein the metallic shield comprises first and second said metallic shields that are crimped and welded together to cover the body.

13. The electrical connection assembly of claim 12 wherein said electrical connection assembly further comprises a sleeve at a rear face of the first and second metallic shields.

14. The electrical connection assembly of claim 13 wherein said electrical connection assembly further comprises an enclosure attached to the connector body.

15. The electrical connection assembly of claim 14 wherein said electrical connection assembly further comprises first and second face plates adhesively attached between the enclosure and the body.

16. The electrical connection assembly of claim 11 wherein said viscous adhesive is dispensed on the printed circuit board from one or more nozzles using a high pressure high accuracy jetting action.

17. The electrical connection assembly of claim 16 wherein said viscous adhesive is UV cured after being dispensed.

18. The electrical connection assembly of claim 11 wherein at least one of the plurality of soldered wires provides a first conductive path to a ground terminal.

19. The electrical connection assembly of claim 18 wherein the cable'"'"'s braid, the first and second metallic shields and a metal ground ring defining a shape of the plug are electrically coupled to form a second conductive path to the ground terminal.

20. The electrical connection assembly of claim 19 wherein a plurality of the cable'"'"'s braid are coupled to the cable wires forming the first conductive path to the ground terminal.
