Abstract

A conductive enclosure for a connector mounted to a circuit board is disclosed, and the enclosure is made in the form of a shroud having an enclosure portion that receives one connector therein and a receptacle portion for receiving a second connector therein that is mateable with the one connector. The enclosure portion includes an internal cavity that is defined by a plurality of walls, two of the walls have retaining members formed thereon that engage the one connector and fix a position of the one connector within the internal cavity, while a third wall of the enclosure portion includes a press member that is biased to exert a force upon the one connector when enclosed in the shroud. The retaining members provide reaction surfaces that at least partially resist the force exerted on the one connector by the press member.

Claims

1. An electronic connector assembly comprising:

a printed circuit board including a plurality of electrically conductive traces;

a socket connector including a plurality of terminals, the socket connector being disposed on the printed circuit board such that the terminals are operatively connected to the traces; and

,

a shroud for enclosing said socket connector, the shroud including an internal cavity operatively connected to the printed circuit board such that a substantial portion of the socket connector is disposed within the shroud internal cavity, the shroud further including a press arm having a free end which contacts a first surface of the socket connector in order to maintain the socket connector in a desired orientation relative to the printed circuit board.

2. The electronic connector assembly as recited in claim 1, wherein the free end exerts a force on the socket connector in the direction of the printed circuit board.

3. The electronic connector assembly as recited in claim 1, wherein the internal cavity is defined by a plurality of walls and the press arm is integrally formed in one of the walls.

4. The electronic connector assembly as recited in claim 1, wherein the shroud includes a rear wall and a top wall, and the press arm is integrally formed in the rear wall and extends cantilevered within a slot defined in the top wall.

5. The electronic connector assembly as recited in claim 1, wherein the press arm free end is disposed such that contact with the socket connector is intermediate opposed ends of the socket connector.

6. The electronic connector assembly as recited in claim 1, wherein the first surface of the socket connector includes a shield and the press arm includes a conductive portion disposed thereon for contacting the shield to define a ground communication path between the shield and the traces.

7. The electronic connector assembly as recited in claim 1, wherein the socket connector includes a series of mounting feet for engaging holes formed in the circuit board and at least one extension disposed adjacent the mounting feet which contacts the printed circuit board and limits engagement between said mounting feet and said printed circuit board.

8. The electronic connector assembly as recited in claim 1, wherein said shroud is formed from a plastic and is plated with a conductive coating so that points of contact between said shroud and said socket connector establish conductive, electrical paths.

9. The electronic connector assembly as recited in claim 1, wherein said shroud includes a plurality of walls, and a first plurality of said walls defines an enclosure portion of said shroud that receives said socket connector therein, and a second plurality of walls that defines a receptacle portion for receiving a plug connector that mates with said socket connector.

10. The electronic connector assembly as recited in claim 3, wherein said shroud further includes at least two retaining members formed therewith which are spaced apart from said press arm and which engage said socket connector on second and third surfaces of said socket connector.

11. The electronic connector assembly as recited in claim 10, wherein said two retaining members are formed on a pair of opposing walls of said shroud and said press arm is formed on a different wall fo said shroud.

13. The shroud as claimed in claim 12, and wherein said shroud includes means for attaching said shroud to a circuit board and said press arm exerts a force on the socket connector in the direction of the printed circuit board so that the circuit board is disposed beneath said shroud and said socket connector when said shroud is applied to said socket connector and said shroud and socket connector are both mounted to a circuit.

14. The shroud as claimed in claim 12, wherein said second set of walls includes a rear wall and a top wall, and said press arm is integrally formed in the rear wall and extends cantilevered within a slot defined in the top wall.

15. The shroud as claimed in claim 14, wherein said second set of walls further includes a pair of sidewalls extending at an angle from said rear and top walls, and said first wall is one of said sidewalls.

16. The shroud as claimed in claim 15, further including a second retaining member formed in the other of said sidewalls, each of said retaining members having a shoulder portions that extends into said cavity, said shoulders defining reaction surfaces that engage said socket connector and resist force applied to said socket connector by said press arm

18. The shroud as claimed in claim 16, wherein said shoulder portions are spaced apart from and disposed opposite said press arm free end.

19. The shroud as claimed in claim 18, wherein said should portions lie in a common plane.

17. The shroud as claimed in claim 12, wherein said shroud includes a conductive coating such that said shroud defines an electrically conductive path between said shroud and said socket connector shield.

20. A shroud for retaining a socket connector on a circuit board, the socket connector having an exterior conductive shield and having a plurality of terminal tail portions that are attachable to the circuit board, comprising:

a hollow body including an internal cavity that receives at least a portion of said socket connector therein when said shroud is applied to said socket connector, a receptacle portion for receiving a plug connector that is mateable with said socket connector, the shroud body including a pair of retaining members formed in opposing walls of the cavity, the retaining members extending into said cavity so as to engage first surfaces of said socket connector when said shroud is applied to said socket connector, the body being conductive so as to provide a conductive electrical path between said shroud and said socket connector; and

,

a press arm having a free end which contacts a second surface of the socket connector, the press arm free end extending at least partially into said cavity in a cantilevered manner in opposition to said retaining members, the press arm having a free end that contacts a second surface of said socket connector when said shroud is applied to said socket connector, said press arm free end opposing said retaining members so that said retaining members resist force exerted on said socket connector by said press arm free end.
