Abstract

A ruggedized electrical receptacle that has a shell configured to receive an interface of a mating connector and a contact subassembly received in the shell. The contact subassembly includes a contact printed circuit board, interface contacts coupled to one face of the contact printed circuit board, termination contacts coupled to the other face thereof, and an overmold overmolded on the board. The overmold surrounds the contact printed circuit board such that free ends of the interface contacts are exposed and tail ends of the termination contacts are exposed. An internal sealing member is disposed between an outer surface of the overmold and the inner surface of the shell, thereby creating a seal therebetween.

Claims

1. A ruggedized electrical receptacle, comprising:

a shell including an inner surface defining an inner receiving area having front and rear sections, the front section being configured to receive an interface of a mating connector;

a contact subassembly received in the shell, the contact subassembly comprising,

a contact printed circuit board with first and second opposing faces,

a plurality of interface contacts coupled to the first face of the contact printed circuit board and a plurality of termination contacts coupled to the second face of the contact printed circuit board, and

an overmold overmolded onto the contact subassembly, the overmold surrounding the contact printed circuit board such that free ends of the plurality of interface contacts are exposed and extend toward the front section of the shell for engaging the mating connector and tail ends of the plurality of termination contacts are exposed and extend toward the rear section of the shell for engagement with a main printed circuit board; and

an internal sealing member disposed between an outer surface of the overmold and the inner surface of the shell, thereby creating a seal therebetween.

2. The electrical receptacle of claim 1, wherein the internal sealing member is a sealing gasket that extends around an outer perimeter of the overmold.

3. The electrical receptacle of claim 1, wherein the outer perimeter of the overmold has groove therein and the sealing gasket is received in the groove.

4. The electrical receptacle of claim 1, wherein the overmold is formed of high temperature glass filled nylon.

5. The electrical receptacle of claim 2, wherein the sealing gasket is formed of silicone rubber.

6. The electrical receptacle of claim 1, wherein the overmold is received in the rear section of the shell.

7. The electrical receptacle of claim 6, further comprising an insulator housing positioned in the front section of the shell such that the free ends of the plurality of interface contacts extend into the insulator housing.

8. The electrical receptacle of claim 7, further comprising a rear contact support coupled to a rear end of the shell such that the tail ends of the plurality of termination contacts extend through the rear contact support.

9. The electrical receptacle of claim 8, wherein the tails ends generally form a right angle.

10. The electrical receptacle of claim 8, wherein the tail ends are generally straight.

11. The electrical receptacle of claim 1, further comprising one or more LEDs coupled to a front side of the overmold with contact tails thereof extending through the overmold.

12. The electrical receptacle of claim 11, further comprising a secondary internal sealing member disposed around the contact tails of the one or more LEDs and abutting the front side of the overmold.

13. The electrical receptacle of claim 12, wherein the secondary internal sealing member is another sealing gasket.

14. The electrical receptacle of claim 1, further comprising an external sealing member positioned on an outer surface of the shell.

15. The electrical receptacle of claim 1, wherein the receptacle is devoid of epoxy or adhesive.

16. A ruggedized electrical receptacle, comprising:

a shell including an inner receiving area having front and rear sections, the front section being configured to receive an interface of a mating connector;

a contact subassembly received in the shell, the contact subassembly comprising,

a contact printed circuit board with first and second opposing faces, at least one of the first and second opposing faces having capacitive compensation circuits,

a plurality of interface contacts coupled to the first face of the contact printed circuit board and a plurality of termination contacts coupled to the second face of the contact printed circuit board, and

an overmold overmolded onto the contact subassembly, the overmold surrounding the contact printed circuit board such that free ends of the plurality of interface contacts are exposed and extend toward the front section of the shell for engaging the mating connector and tail ends of the plurality of termination contacts are exposed and extend toward the rear section of the shell for engaging a main printed circuit board; and

an internal sealing member disposed around an outer perimeter of the overmold, thereby creating a seal therebetween between the overmold and the shell.

17. The electrical receptacle of claim 16, further comprising an insulator housing positioned in the front section of the shell such that the free ends of the plurality of interface contacts extend into the insulator housing;

and a rear contact support coupled to a rear end of the shell such that the tail ends of the plurality of termination contacts extend through the rear contact support.

18. The electrical receptacle of the claim 16, further comprising one or more LEDs coupled to a front side of the overmold with contacts thereof extending through the overmold;

and a secondary internal sealing member disposed around the one or more LEDs and abutting the front side of the overmold.

19. The electrical receptacle of claim 18, further comprising an external sealing member positioned on an outer surface of the shell;

and each of the internal sealing member, secondary internal sealing member, and external sealing member, is a sealing gasket.

20. The electrical receptacle of claim 19, wherein the receptacle is devoid of epoxy or adhesive.
