Abstract

A terminal grounding unit for use in interconnecting a plug-in circuit board with a backplane of equipment mounting apparatus. The terminal grounding unit comprises an insulating member having a row and column configuration of apertures intended for receiving pin terminals of the backplane to mount the insulating member on the backplane with the pin terminals extending outward therefrom to engage contact terminals of a connector mounted on the plug-in circuit board. Apparatus positioned in the insulating member between columns of the pin terminals slidably receives and interconnects a shield member of the plug-in circuit board connector with a backplane ground path.

Claims

1. Apparatus for use with a backplane of equipment mounting apparatus to interconnect contact terminals and a shielding member of a connector with pin terminals and ground paths of the backplane comprising

insulating means for receiving the pin terminals to mount said insulating means on the backplane with the pin terminals extending outward therefrom to engage the connector contact terminals, and

means positioned in said insulating means between columns of the pin terminals for slidably receiving and interconnecting the connector shielding member with the backplane ground paths to shield the connector engaged with the backplane.

2. The apparatus set forth in claim 1 wherein said insulating means comprises

a generally quadrilateral configured member formed of insulating material and having a plurality of apertures formed in a row and column configuration each for receiving one of the backplane pin terminals.

3. The apparatus set forth in claim 2 wherein said slidably receiving and interconnecting means comprises

a plurality of channels formed in a column configuration on one surface of said insulating member with each channel positioned between adjacent columns of said apertures for slidably receiving the connector shielding member.

4. The apparatus set forth in claim 3 wherein said slidably receiving and interconnecting means comprises

terminal means positioned in insulating member channels at locations between adjacent rows of said insulating member apertures for engaging the connector shield member.

5. The apparatus set forth in claim 4 wherein said slidably receiving and interconnecting means comprises

conducting means electrically coupled with said terminal means and the backplane ground path for electrically grounding the connector shielding member.

6. Apparatus for use with a backplane of equipment mounting apparatus to interconnect contact terminals and a shielding member of a connector with pin terminals and ground paths of the backplane comprising

insulating means for receiving the backplane pin terminals in an interference fit to mount said insulating means on the backplane juxtaposed between the backplane and connector with the pin terminals extending perpendicularly outward from a surface thereof to engage the connector contact terminals, and

means positioned in said insulating means between rows and columns of the pin terminals for slidably receiving and interconnecting the connector shielding member with the backplane ground paths to shield ones of the backplane pin terminals and the connector engaged with the backplane.

7. The apparatus set forth in claim 6 wherein said insulating means comprises

a generally quadrilateral configured member formed of electrically insulating material and having a plurality of apertures formed in a row and column configuration with each of said apertures having a conduit for accepting a first part of each backplane pin terminal in said interference fit and a cavity interconnected with said conduit for accepting a compliant portion of each backplane pin terminal projecting above a front surface of the backplane.

8. The apparatus set forth in claim 7 wherein said slidably receiving and interconnecting means comprises

a plurality of slots formed in said insulating member in a row configuration with each slot positioned between adjacent rows of said backplane pin terminal apertures and ones of the slots interconnected by channels formed between adjacent columns of the backplane pin terminal apertures for slidably receiving the connector shielding member.

9. The apparatus set forth in claim 8 wherein said slidably receiving and interconnecting means comprises

a plurality of generally U-shaped contact terminals each positioned in one of said slots with contact surfaces thereof located with respect to said channel interconnecting ones of the slots for slidably engaging the connector shielding member.

10. The apparatus set forth in claim 9 wherein said slidably receiving and interconnecting means comprises

conducting members each coupled with ones of said U-shaped contact terminals positioned in ones of said columns of slots and with the backplane ground paths for electrically grounding the connector shielding member.

11. A terminal grounding unit for use with a backplane of circuit board mounting apparatus to interconnect contact terminals and a shielding member of a plug-in circuit board connector with pin terminals and a ground path of the backplane comprising

a generally quadrilateral configured member formed of electrically insulating material and having a plurality of apertures formed therein in a row and column configuration with each of said apertures formed for receiving the backplane pin terminals in an interference fit to mount said insulating member on the backplane juxtaposed between the backplane and plug-in circuit board connector with the pin terminals extending perpendicularly outward from a surface thereof to engage the plug-in circuit board connector contact terminals,

a plurality of slots formed in said insulating member in a row configuration with each slot positioned between adjacent rows of said backplane pin terminal apertures and with ones of slots interconnected by channels each formed between adjacent columns of said backplane pin terminal apertures for slidably receiving the circuit board connector shielding member,

a plurality of generally U-shaped female contact terminals each positioned in one of said slots with contact surfaces thereof located for engaging the circuit board connector shielding member slidably inserted in said channel, and

electrically conducting means coupled with said U-shaped female contact terminals and with the backplane ground path for electrically grounding the circuit board connector shielding member and shielding ones of the backplane pin terminals.

12. A terminal grounding unit for use in interconnecting a plug-in circuit board mounting apparatus backplane having pin terminals and a ground path with a plug-in circuit board connector having contact terminals and shielding members characterized in that

said terminal grounding unit comprises

an insulating member having a row and column configuration of apertures formed therein for receiving the backplane pin terminals with the backplane pin terminals extending outward therefrom to engage the plug-in circuit board connector contact terminals and having a row configuration of slots positioned between adjacent rows of said backplane pin terminal apertures with ones of said slots interconnected by channels each formed between adjacent columns of said backplane pin terminal apertures for slidably receiving the circuit board connector shielding member, and
