Abstract
Abstract A fiber optic connector member having a removable front plate for protecting the faces of optical fibers mounted within the connector. The plate is retained within the connector shell by a resilient retention finger. The finger extends into a T-shaped slot formed on the outer surface of the plate. The slot opens at the front face of the plate. An extraction tool is disclosed which may be inserted into the slot to release the retention finger and grip shoulders formed on the sides of the slot allowing the plate to be withdrawn from the connector shell by pulling the tool forwardly of the connector.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
171 words
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 a rearwardly facing shoulder on the side of said clearance space.
Claim 2
Dependent Claim
171 words
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 a rearwardly facing shoulder on the side of said clearance space.
Claim 3
Dependent Claim
37 words
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.
Claim 4
Dependent Claim
30 words
A connector as set forth in claim 1 including: a second rearwardly facing shoulder on the side of said clearance space opposite to said first-mentioned side of said clearance space.
Claim 5
Dependent Claim
13 words
A connector as set forth in claim 2 wherein: said slot is T-shaped.
Claim 6
Dependent Claim
15 words
A connector as set forth in claim 1 wherein: said conductive elements comprise optical fibers;
Claim 7
Dependent Claim
196 words
A connector member comprising: a 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 surface 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 a rearwardly facing shoulder on at least one side of each of said clearance slots.
Claim 8
Dependent Claim
196 words
A connector member comprising: a 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 surface 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 a rearwardly facing shoulder on at least one side of each of said clearance slots.
Claim 9
Dependent Claim
115 words
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 retention 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 a rearwardly facing shoulder on the side of said clearance space.
Claim 10
Dependent Claim
115 words
