Abstract

A guide pin for a connector assembly includes a guide pin body extending along a pin axis. The guide pin body has a stem extending between a root and a tip. The root has threads configured to be threadably coupled to a support frame of the connector assembly and the tip has a lead-in to guide the guide pin body into a mounting block. The stem has slots extending parallel to the pin axis from the tip to an intermediate position along the guide pin body remote from the tip. The slots are configured to receive ribs of a driver tool used to rotate the guide pin body to threadably couple the root to the support frame.

First claim

What is claimed is:

1. A guide pin for a connector assembly comprising:
a guide pin body extending along a pin axis, the guide pin body having a stem extending between a root and a tip, the root having threads configured to be threadably coupled to a support frame of the connector assembly, the tip being pointed to provide a lead-in with an end of the tip being less than half of a diameter of the stem of the guide pin body to guide the guide pin body into a mounting block, the stem having slots extending parallel to the pin axis from the tip to an intermediate position along the guide pin body remote from the tip, the slots have a bottom wall and side walls generally perpendicular to the bottom wall, the bottom wall being recessed below an outer perimeter of the guide pin body, wherein the slots are configured to receive ribs of a driver tool used to rotate the guide pin body to threadably couple the root to the support frame.

2. The guide pin of claim 1 , wherein the side walls define bearing surfaces for the driver tool to rotate the guide pin.

3. The guide pin of claim 1 , wherein the bottom walls extends coplanar with and to flat sides formed in the guide pin body.

4. The guide pin of claim 1 , wherein the stem is generally cylindrical having a stem diameter, the bottom walls being separated by a distance less than the stem diameter.

5. The guide pin of claim 1 , wherein the stem is generally cylindrical having a stem diameter, the stem having at least two flat sides formed in the guide pin body being separated by a distance less than the stem diameter.

6. The guide pin of claim 1 , wherein the slots extend at least partially along the tip.

7. The guide pin of claim 1 , wherein the stem includes radiused portions aligned with the slots, the radiused portions being configured to engage the mounting block.

8. The guide pin of claim 1 , wherein the lead-in starts at the end of the tip and extends outward to an outer perimeter of the guide pin body.

9. The guide pin of claim 1 , wherein the tip is cone shaped and the stem is cylindrical shaped with the slots recessed into an outer surface of the stem.

10. The guide pin of claim 1 , wherein the slots are open at a front of the guide pin body.

11. A connector assembly comprising:
a support frame having a cavity, the support frame having a threaded bore;
at least one connector received in the cavity; and
a guide pin coupled to the support frame, the guide pin having a guide pin body extending along a pin axis, the guide pin body having a stem extending between a root and a tip, the root having threads threadably coupled to the threaded bore of the support frame, the tip being pointed to provide a with an end of the tip being less than half of a diameter of the stem of the guide pin body to guide the guide pin body into a mounting block, the stem having slots extending from the tip parallel to the pin axis, the slots have a bottom wall and side walls generally perpendicular to the bottom wall, the bottom wall being recessed below an outer perimeter of the guide pin body, wherein the slots are configured to receive ribs of a driver tool used to rotate the guide pin body to threadably couple the root to the threaded bore.

12. The connector assembly of claim 11 , wherein the support frame includes at least one spacer and frame walls supported by the spacer and defining the cavity, the spacer having the threaded bore, the guide pin being threadably coupled to the spacer.

13. The connector assembly of claim 11 , wherein the side walls define bearing surfaces for the driver tool to rotate the guide pin.

14. The connector assembly of claim 11 , wherein the side walls and bottom wall are recessed below an outer surface of the guide pin body.

15. The connector assembly of claim 11 , wherein the slots extend at least partially along the tip.

16. The connector assembly of claim 11 , wherein the tip is cone shaped and the stem is cylindrical shaped with the slots recessed into an outer surface of the stem.

17. The connector assembly of claim 11 , wherein the slots are open at a front of the guide pin body.

18. A cable backplane system comprising:
a backplane having a plurality of openings therethrough, the backplane having mounting blocks proximate the openings; and
a cable rack coupled to a rear of the backplane, the cable rack comprising:
a tray having frame walls surrounding a raceway;
cable connector assemblies supported by corresponding frame walls, each cable connector assembly having a support frame defining a cavity, the support frame having spacers with threaded bores, each cable connector assembly having at least one cable connector received in the cavity, each cable connector having a plurality of cables extending therefrom into the raceway, each cable connector being received in a corresponding opening in the backplane and held in position relative to the backplane by the support frame; and
a plurality of guide pins coupled to corresponding spacers, each guide pin having a guide pin body extending along a pin axis, the guide pin body having a stem extending between a root and a tip, the root having threads threadably coupled to the corresponding threaded bore, the tip being pointed to provide a lead-in with an end of the tip being less than half of a diameter of the stem of the guide pin body to guide the guide pin body into the mounting block, the stem having slots extending from the tip parallel to the pin axis to an intermediate position along the guide pin body remote from the tip, the slots have a bottom wall and side walls generally perpendicular to the bottom wall, the bottom wall being recessed below an outer perimeter of the guide pin body, wherein the slots are configured to receive ribs of a driver tool used to rotate the guide pin body to threadably couple the root to the threaded bore.
