Abstract

The present invention is directed to a socket connector to couple electrical plugs to sockets mounted on circuit boards or cable ends. The socket connector includes a socket that receives an electrical plug and a socket silo. The silo may contain a beveled outer surface that receives a beveled face on the plug. The plug is held in the socket by latches disposed on the plug. The latches include pawls that fit within pawl receiving chambers in the socket and couple the plug to the socket. The latch and hinged section may rotate into a recessed section on the plug from an extended to a retracted position. A locking portion on the pawl and the receiving chamber may be angled to develop a desired pullout force

Claims

1. A socket silo for electrically coupling an electrical plug to a circuit board comprising:

a tower having an outer receiving surface, the outer receiving surface including at least one socket for receiving a conductive pin, the tower being affixed to a top surface of a support shelf;

at least one tower leg disposed on a bottom surface of the support shelf;

a planar filter array having at least one filter leg disposed on a bottom surface thereof;

an open gallery created by the intersection of the bottom surface of the support shelf and the at least one leg, tower the planar filter array being disposed within the open gallery the filter leg and a portion of the at least one tower leg extending below the planar filter array and engageable with the circuit board; and

a conductor disposed on the inside of the socket extending from a distance below the outer receiving surface to beyond the bottom surface of the support shelf.

2. The socket silo according to claim 1, wherein the open gallery is formed by the intersection of two legs with the bottom surface of the support shelf.

3. The socket silo according to claim 1, wherein the outer receiving surface is beveled having first and second edge portions, the receiving surface sloping monotonically between the first and second edge portions and defining a socket opening located between the first and second edge portions.

4. The socket silo according to claim 1, wherein the tower has a trapezoidal cross-section.

5. The socket silo according to claim 1, wherein the planar filter array is ferrite through which the conductor passes.

6. The socket silo according to claim 1, wherein the planar filter array is a collection of capacitors through which the conductor passes.

7. A socket silo for electrically coupling an electrical plug to a circuit board comprising:

a tower having a beveled outer receiving surface, the beveled outer receiving surface including at least one socket for receiving conductive pin, the at least one socket defining an opening in the beveled outer receiving surface; and

an electrical conductor disposed on an inside of the socket, the electrical conductor being operable to be electrically coupled with the conductive pin.

8. The socket silo according to claim 7, further comprising:

a planar filter array having at least one filter leg disposed on a bottom surface thereof;

a support shelf on which the tower is disposed;

at least one leg disposed on a bottom surface of the support shelf;

an open gallery created by the intersection of the bottom surface of the support shelf and the at least one leg, the planar filter array disposed within the open gallery having the filter leg and a portion of the at least one tower leg extending below the planar filter array and engageable with the circuit board; and

the electrical conductor disposed on the inside of the socket extending from a distance below the outer receiving surface to beyond the bottom surface of the support shelf.

9. The socket silo according to claim 8, wherein the open gallery is formed by the intersection of two legs with the bottom surface of the support shelf.

10. The socket silo according to claim 8, wherein the planar filter array is ferrite through which the conductor passes.

11. The socket silo according to claim 8, wherein the planar filter array is a collection of capacitors through which the conductor passes.

12. The socket silo according to claim 7, wherein the tower has a trapezoidal cross-section.

13. The socket silo according to claim 7, wherein the beveled outer receiving surface on the tower is configured to mate snugly with a beveled face disposed on the plug.

14. The socket silo according to claim 7, wherein the beveled outer receiving surface of the tower comprises a crown operable to prevent the electrical coupling of the electrical conductor and a pin disposed on a plug not having a beveled face.

15. The socket silo according to claim 7, wherein the tower has a color corresponding to a color on a plug which may be used with the silo.
