Abstract

A cable pulling assembly includes an enclosure that is adapted for enclosing an SC type connector end of a fiber optic cable. The enclosure includes a first member that defines a first cavity. The first cavity is adapted to receive a portion of a SC connector. The enclosure further includes a second member that is selectively engaged to the first member. The second member defines a second cavity. The second member may be structurally identical to the first member. The enclosure is adapted to transfer a tensile force applied to the enclosure to the strength layer of the fiber optic cable.

First claim

What is claimed is:

1. A removable cable pulling assembly comprising:
a removable enclosure adapted for enclosing an end of a fiber optic cable, wherein the end of the fiber optic cable includes an SC-type (SC) connector with a release sleeve, the removable enclosure including:
a removable first member defining a first cavity, the first cavity being adapted and contoured to removably engage a first portion of an SC connector and the first cavity being adapted to receive the end of the fiber optic cable, wherein the first cavity defines a first shoulder, wherein the first shoulder is positioned on the removable first member to engage and pass through a first opening defined in the release sleeve; and
a removable second member being adapted to removably engage the removable first member, the removable second member defining a second cavity, wherein the second cavity defines a second shoulder, wherein the second shoulder is positioned on the removable second member to engage and pass through a second opening defined in the release sleeve opposite to the first opening;

wherein the removable enclosure is adapted to transfer a tensile force applied to the removable enclosure to a strength layer of the fiber optic cable.

2. The removable cable pulling assembly of claim 1 , wherein the first cavity receives a portion of the SC connector and the second cavity receives a remaining portion of the SC connector.

3. The removable cable pulling assembly of claim 1 , wherein the removable enclosure is adapted to engage an axial end of the SC connector when the tensile force is applied to the removable enclosure so that the tensile force is applied to the strength layer through the SC connector.

4. The removable cable pulling assembly of claim 1 , wherein each of the removable first member and second member includes a plurality of resilient tabs and a plurality of grooves, the plurality of grooves of the removable first member being adapted to receive the plurality of resilient tabs of the removable second member and the plurality of grooves of the removable second member being adapted to receive the plurality of resilient tabs of the removable first member.

5. The removable cable pulling assembly of claim 4 , wherein each of the removable first member and the removable second member includes a first resilient tab and a second resilient tab, the first resilient tab and the second resilient tab being disposed on opposite sides of a longitudinal axis of the removable enclosure.

6. The removable cable pulling assembly of claim 1 , wherein at least one of the removable first member and the removable second member is translucent.

7. The removable cable pulling assembly of claim 1 , wherein the removable second member is structurally identical to the removable first member.

8. The removable cable pulling assembly of claim 1 , further comprising a cable terminated by an SC connector, wherein the removable enclosure engages at least one ridge, and preferably two ridges, of the SC connector inner front housing.

9. The removable cable pulling assembly of claim 1 , wherein when the first and second shoulders engage and pass through the respective first and second openings, the first and second shoulders respectively engage first and second ridges on opposite sides of the release sleeve.

10. A removable cable pulling assembly comprising:
a removable enclosure adapted for enclosing an end of a fiber optic cable, wherein the end of the fiber optic cable includes an SC connector, the removable enclosure including:
a removable first member, the removable first member including:
a first body having a longitudinal surface, the first body defining a first blind cavity having an opening in the longitudinal surface of the first body, wherein the first blind cavity is defined by a first shoulder, wherein the first shoulder is positioned on the removable first member to engage and pass through a first opening defined in the SC connector, when the first shoulder passes through the first opening, the first shoulder engages a first catch of the SC connector; and
a first plurality of resilient tabs engaged to the first body, the first plurality of resilient tabs extending beyond the longitudinal surface of the first body; and

a removable second member, the removable second member including:
a second body having a longitudinal surface, the second body defining a second blind cavity having an opening in the longitudinal surface of the second body, wherein the second blind cavity is defined by a second shoulder, wherein the second shoulder is positioned on the longitudinal surface of the second body to engage and pass through a second opening defined in the SC connector, when the second shoulder passes through the second opening, the second shoulder engages a second catch of the SC connector; and
a second plurality of resilient tabs engaged to the second body, the second plurality of resilient tabs extending beyond the longitudinal surface of the second body, the second plurality of resilient tabs adapted for engagement with the removable first member;

wherein the end of the fiber optic cable is enclosed between the first blind cavity and the second blind cavity;

wherein the removable enclosure is adapted to transfer a tensile force applied to the removable enclosure to a strength layer of the fiber optic cable.

11. The removable cable pulling assembly of claim 10 , wherein the longitudinal surface of each of the first body and the second body includes a plurality of alignment guides that extends outwardly from the longitudinal surface of the first body and the longitudinal surface of the second body.

12. The removable cable pulling assembly of claim 10 , wherein each of the removable first member and the removable second member defines a thru-passage that extends through a first axial end portion of each of the removable first member and the removable second member.

13. The removable cable pulling assembly of claim 10 , wherein the removable first member includes a first plurality of grooves adapted to receive the second plurality of resilient tabs of the removable second member and the removable second member includes a second plurality of grooves adapted to receive the first plurality of resilient tabs of the removable first member.

14. The removable cable pulling assembly of claim 10 , wherein at least one of the removable first member and the removable second member is translucent.

15. The removable cable pulling assembly of claim 10 , wherein the removable second member is structurally identical to the removable first member.

16. A cable pulling assembly comprising:
a fiber optic cable having an end;
an SC connector engaged to the end of the fiber optic cable; and
a removable enclosure enclosing the SC connector of the fiber optic cable, the removable enclosure including:
a removable first member defining a first cavity, the first cavity being adapted and contoured to removably engage a portion of the SC connector of the fiber optic cable, wherein the first cavity is defined by a first shoulder wherein the first shoulder is positioned on the removable first member to engage and pass through a first void defined in the SC connector; and
a removable second member being removably engaged to the removable first member, the removable second member defining a second cavity, the second cavity being adapted and contoured to receive a remaining portion of the SC connector of the fiber optic cable, wherein the second cavity is defined by a second shoulder, wherein the second shoulder is positioned on the removable second member to engage
