Abstract

A protector for protecting components of a partially pre-assembled multi-fiber connector without increasing a cross-sectional profile of the partially pre-assembled connector may include a housing portion having a receiving portion configured to receive a partially pre-assembled multi-fiber connector portion of a multi-fiber push on (MPO) connector. The receiving portion may be configured to extend from an opening portion at a first end portion of the housing portion to a wall portion at a second end portion of the housing portion. The housing portion may be configured to be coupled with a biasing portion of a partially pre-assembled multi-fiber connector without increasing a cross-sectional profile of the partially pre-assembled connector so as to permit the housing portion to protect components of the pre-assembled multi-fiber connector during pushing and/or pulling of the pre-assembled multi-fiber connector through a conduit that is sized to receive the partially pre-assembled multi-fiber connector and to prevent passage of a fully assembled MPO connector.

Claims (36)

1 . A protector configured to protect components of a partially pre-assembled multi-fiber connector without increasing a cross-sectional profile of the partially pre-assembled connector, comprising:

a housing portion having a first end portion, a second end portion opposite to the first end portion, and a receiving portion configured to receive a partially pre-assembled multi-fiber connector portion of a multi-fiber push on (MPO) connector;

wherein the receiving portion is configured to include an opening portion at the first end portion, and wherein a cavity portion extends from the opening portion to a wall portion at the second end portion;

wherein the housing portion includes two opposed first side wall portions and two opposed second side wall portions, and wherein each of the two opposed second side wall portions is connected to the two opposed first side wall portions so as to provide the receiving portion with a rectangular cross sectional profile;

wherein the two opposed first side wall portions include an engagement portion;

wherein the engagement portion includes an engagement feature configured to receive an engagement structure of a partially pre-assembled multi-fiber connector; and

wherein the housing portion is configured to be coupled with a biasing portion of a partially pre-assembled multi-fiber connector without increasing a cross-sectional profile of the partially pre-assembled connector so as to permit the housing portion to protect components of the pre-assembled multi-fiber connector during pushing and/or pulling of the pre-assembled multi-fiber connector through a conduit that is sized to receive the partially pre-assembled multi-fiber connector and to prevent passage of a fully assembled MPO connector.

2 . The protector of claim 1 , wherein the engagement feature comprises one of a hole, an opening, or a notch.

3 . The protector of claim 1 , wherein the housing portion includes a friction reduction portion structurally configured to reduce friction with a conduit as the protector is pushed or pulled through the conduit.

4 . The protector of claim 3 , wherein the friction reduction portion comprises rounded corner portions where the first side wall portions meet the second side wall portions.

5 . The protector of claim 3 , wherein the friction reduction portion comprises an extension portion configured to extend outward from an outer surface of the second side wall portions.

6 . The protector of claim 5 , wherein the extension portion comprises an elongated projection having a smaller surface area than the second side walls so as to reduce a surface area of the protector that is configured to contact an inner surface of a conduit.

7 . A protector configured to protect components of a partially pre-assembled multi-fiber connector without increasing a cross-sectional profile of the partially pre-assembled connector, comprising:

a housing portion having a first end portion, a second end portion opposite to the first end portion, and a receiving portion configured to receive a partially pre-assembled multi-fiber connector portion of a multi-fiber push on (MPO) connector;

wherein the receiving portion is configured to include an opening portion at the first end portion, and wherein a cavity portion extends from the opening portion to a wall portion at the second end portion;

wherein the housing portion is structurally configured to include an engagement portion that is configured to receive an engagement structure of a partially pre-assembled multi-fiber connector; and

wherein the housing portion is configured to be coupled with a biasing portion of a partially pre-assembled multi-fiber connector without increasing a cross-sectional profile of the partially pre-assembled connector so as to permit the housing portion to protect components of the pre-assembled multi-fiber connector during pushing and/or pulling of the pre-assembled multi-fiber connector through a conduit that is sized to receive the partially pre-assembled multi-fiber connector and to prevent passage of a fully assembled MPO connector.

8 . The protector of claim 7 , wherein the engagement portion comprises one of a hole, an opening, or a notch.

9 . The protector of claim 7 , wherein the housing portion includes a friction reduction portion structurally configured to reduce friction with a conduit as the protector is pushed or pulled through the conduit.

10 . The protector of claim 9 , wherein the housing portion includes two opposed first side wall portions and two opposed second side wall portions.

11 . The protector of claim 10 , wherein each of the two opposed second side wall portions is connected to the two opposed first side wall portions so as to provide the receiving portion with a rectangular cross sectional profile.

12 . The protector of claim 10 , wherein the friction reduction portion comprises rounded corner portions where the first side wall portions meet the second side wall portions.

13 . The protector of claim 10 , wherein the friction reduction portion comprises an extension portion configured to extend outward from an outer surface of the second side wall portions.

14 . The protector of claim 13 , wherein the extension portion comprises an elongated projection having a smaller surface area than the second side walls so as to reduce a surface area of the protector that is configured to contact an inner surface of a conduit.

15 . A protector configured to protect components of a partially pre-assembled multi-fiber connector without increasing a cross-sectional profile of the partially pre-assembled connector, comprising:

a housing portion having a receiving portion configured to receive a partially pre-assembled multi-fiber connector portion of a multi-fiber push on (MPO) connector;

wherein the receiving portion is configured to extend from an opening portion at a first end portion of the housing portion to a wall portion at a second end portion of the housing portion; and

wherein the housing portion is configured to be coupled with a biasing portion of a partially pre-assembled multi-fiber connector without increasing a cross-sectional profile of the partially pre-assembled connector so as to permit the housing portion to protect components of the pre-assembled multi-fiber connector during pushing and/or pulling of the pre-assembled multi-fiber connector through a conduit that is sized to receive the partially pre-assembled multi-fiber connector and to prevent passage of a fully assembled MPO connector.

16 . The protector of claim 15 , wherein the housing is configured to include an engagement portion that is configured to receive an engagement portion of a partially pre-assembled multi-fiber connector.

17 . The protector of claim 16 , wherein the engagement portion comprises one of a hole, an opening, or a notch.
