Abstract

There is disclosed a press-fit pinless latching shroud. The latching shroud retains a connector to a pinfield with two flexible interlocking arms. The connector may be removed from the shroud by the user by disengaging the flexible arms from the connector. The latching shroud mounts to the pinfield by creating an interference fit between a portion of the pinfield and a series of matching holes in its base.

Claims

1. A system for retaining at least one connector with at least one shroud, each connector containing a plurality of sockets, the sockets mating with a plurality of pins protruding from a surface, the connector having a length and a width, the pins part of a pinfield, the pinfield having a length and a width, each of said shrouds further comprising:

a base member for securely mounting the shroud on a portion of the pinfield, the base member having a length and a width, the length of the base member shorter than the length of the pinfield and shorter than the length of the connector; and

means for removably attaching the connector to the shroud and holding the connector on the plurality of pins while the shroud is mounted to the pins.

2. The system of claim 1 wherein said base member further comprises:

a plurality of passage ways for receiving the pins covered by said base member, said passage ways sized toc reate an interference fit with said covered pins; and

means for spacing said base member above the surface.

3. The system of claim 2 wherein said spacing means further comprises at least two leg members attached to said base member.

4. The system of claim 2 wherein said passage ways further comprise:

a tapering entry way with an opening larger than the pins; and

an exit way in connection with said entry way with a substantially similar cross-section as the pins.

5. The system of claim 1 wherein the pins are aligned in rows and wherein said attaching means further comprises a set of brackets spaced across a plurality of said holes, the brackets interlocking with the connector.

6. The system of claim 5 wherein said brackets form an opening above said base member for retaining at least one connector narrower than the shroud.

7. The system of claim 1 wherein the pins are aligned in rows, and wherein the shroud further comprises means aligned across the width of the pins for indexing a specified set of the pins.

8. The system of claim 1 wherein the pins are wire wrap tails of backplane connectors.

9. The shroud of claim 1 wherein the pins form a 0.1 inch×

0.1 inch matrix.

10. The shroud of claim 1 wherein said pins form a 0.1 inch×

0.2 inch matrix.

11. A system for retaining at least one connector with at least one shroud, each connector containing a plurality of sockets, the connector having a length and a width, the sockets mating with the plurality of regularly spaced pins protruding from a surface, the pins part of a pinfield, the pinfield having a length and a width said shroud comprising:

a base member containing a plurality of holes for receiving the pins covered by said base member, said base member having a length and a width, the length of the base member shorter than the length of the pinfield and shorter than the length of the connector, said holes having a tapering entry way with an opening larger than the pins leading to an exit way with a cross-section substantially similar to the cross section of the pins;

at least two leg members attached to said base member operable for causing said base to be positioned away from the surface; and

two brackets aligned across the width of said holes and attached to said base operable for receiving the connector in a temporarily interlocked manner.

12. The system of claim 11 wherein at least one of the shrouds further comprises a thin member connecting said brackets to index a specific row of said pins by fitting between adjacent ones of such rows.

13. The system of claim 11 wherein the regularly spaced pins form a 0.1 inch×

0.1 inch matrix.

14. The system of claim 11 wherein the regularly spaced pins form a 0.1 inch×

0.2 inch matrix.

15. The system of claim 11 wherein teh regularly spaced pins are wire wrap tails of backplane connectors.

16. The system of claim 11 wherein said brackets form an opening above said base member for retaining at least one connector narrower than the shroud.

17. The method of attaching a connector with a first and second end to a pinfield, the pinfield having a length and a width, the method comprising the steps of:

mounting a shroud on a portion of the pinfield causing a portion of the pinfield covered by the shroud to protrude through the shroud thereby creating an itnerference fit between the portion of the pinfield and the shroud the shroud having a length and a width, the length of the shroud shorter than the length of the pinfield;

mating the connector with part of the portion of the pinfield protruding through the shroud and part of the pinfield not protruding through the shroud; and

engaging a locking mechanism on the shroud with the connector.

18. The method of claim 17 wherein the locking mechanism on the shroud further comprises a pair of brackets aligned across the width of the pinfield.

19. The method of claim 17 wherein the pinfield is a 0.1 inch×

0.1 inch matrix.

20. The method of claim 17 wherein the pinfield is a 0.1 inch×

0.2 inch matrix.

21. The method of claim 17 wherein said mounting step further comprises the step of spacing the shroud a specific height above the base of the pinfield.

22. The method of claim 17 further comprising the step of indexing a particular row of pins in the pinfield.
