Abstract

A fiber optic connector member having a removable front insulator for protecting the faces of fiber optic bundles mounted within the connector. The insulator is retained within the connector shell by resilient retention fingers. An elongated slot extends through the insulator. An extraction tool is provided for releasing the retention fingers. The tool embodies a pulling element that extends through the slot in the insulator to allow the insulator to be withdrawn from the connector shell without damaging the fiber optic elements therein.

Claims

1. A connector member comprising:

a shell containing a rear fixed support member and a front support member slidably removable from the forward end of said shell;

each said support member having a forward face and a rear face;

a plurality of conductive elements mounted in said rear support member extending at least to said forward face thereof but terminating behind said forward face of said front support member;

said shell having an inner surface;

said front support member having a forwardly facing shoulder thereon adjacent to said shell inner surface and behind said forward end of said shell;

said shell having at least one resilient retention finger extending inwardly and rearwardly from said inner surface thereof engaging said shoulder to limit forward movement of said front support member in said shell;

means defining a clearance space between said shell inner surface and said front support member extending from said shoulder to said forward face of said front support member; and

an elongated slot in said front support member extending rearwardly from said forward face thereof to a rearwardly facing surface on said front support member.

2. A connector as set forth in claim 1 wherein:

said clearance space defining means comprises a slot in the outer surface of said front support member, said slot being wider than the width of said retention finger.

3. A connector as set forth in claim 1 including:

a second one of said shoulders, retention fingers and clearance space defining means each disposed on the side of its respective shell and front support member opposite to said first mentioned shoulder, retention finger and clearance space defining means.

4. A connector as set forth in claim 1 including:

a recess in said front support member aligned with said slot and opening at said rear face of said front support member, said slot opening at the bottom of said recess.

5. A connector as set forth in claim 4 wherein:

the cross-section of said recess is greater than the width of said slot.

6. A connector as set forth in claim 4 wherein:

said recess is cylindrical, the diameter of said recess being at least as great as the length of said slot.

7. A connector as set forth in claim 1 wherein:

said conductive elements are optical fibers.

8. A connector member comprising:

a generally rectangular shell containing a rear relatively fixed support member and a front support member slidably removable from the forward end of said shell;

each said support member having a forward face and a rear face, said front support member having top and bottom surfaces;

a plurality of conductive elements mounted in said rear support member extending at least to said forward face thereof but terminating behind said forward face of said front support member;

said shell having top and bottom inner surfaces;

said front support member having forwardly facing shoulders on said top and bottom surfaces thereof adjacent to said shell top and bottom inner surfaces and behind said forward end of said shell;

said shell having at least one resilient retention finger extending inwardly and rearwardly from said top and bottom inner surfaces thereof engaging said shoulders to limit forward movement of said front support member in said shell;

clearance slots in said top and bottom surfaces of said front support member extending from said shoulders to said forward face of said front support member; and

an elongated slot in said front support member extending rearwardly from said forward face thereof to a rearwardly facing surface on said front support member.

9. In a connector member, the combination comprising:

a shell having a support member slidably removable from the forward end of said shell;

said support member having a forwardly facing shoulder thereon inside said shell, a forward face and a rear face, conductor receiving passages in said support member extending from said forward face to said rear face;

said shell having a resilient retnetion finger extending inwardly and rearwardly from the inner surface of said shell engaging said shoulder to retain said support member within said shell;

means defining a clearance space extending from said shoulder to said forward face of said support member; and

an elongated, tool receiving slot in said support member in addition to said passages extending rearwardly from said forward face to a rearwardly facing surface on said support member.

10. A connector member as set forth in claim 9 including:

a fiber optic bundle extending forwardly into each of said passages, each said bundle having a forward mating end terminating behind said forward face of said support member.
