Abstract

A cable pulling assembly includes an enclosure that is adapted for enclosing an 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 the end of the fiber optic cable. 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 is 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 and a fiber optic connector positioned at the end of the fiber optic cable, the removable enclosure including:
a removable first member defining a first cavity including a first end portion, the first end portion of the first cavity being adapted and contoured to removably engage the connector and to receive the end of the fiber optic cable; and
a removable second member structurally identical to the removable first member and being adapted to removably engage the removable first member and to be separable from the removable first member, the removable second member being kinematically independent from the removable first member upon separation from the removable first member, and the removable second member defining a second 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 by engagement of the first end portion of the first cavity with the connector.

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

3. The removable cable pulling assembly of claim 2 , wherein the removable enclosure is adapted to engage an axial end of the connector when the tensile force is applied to the removable enclosure so that the tensile force is applied to the strength layer through the connector.

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

5. The removable cable pulling assembly of claim 4 , wherein each of the removable first and second members includes a first resilient tab and a second resilient tab, the first and second resilient tabs 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 and second members is translucent.

7. The removable cable pulling assembly of claim 1 , wherein at least one of the removable first and second members defines a thru-passage that extends through a first axial end portion of the at least one of the removable first and second members.

8. The removable cable pulling assembly of claim 1 , wherein the removable second member is adapted to removably engage the removable first member via a removable snap-fit engagement.

9. The removable cable pulling assembly of claim 1 , wherein the second cavity of the removable second member includes a second end portion that is also adapted and contoured to removably engage the connector and wherein the second cavity is also adapted to receive the end of the fiber optic cable.

10. The removable cable pulling assembly of claim 9 , wherein the removable enclosure is further adapted to transfer the tensile force applied to the removable enclosure to the strength layer of the fiber optic cable by engagement of the second end portion of the second cavity with an axial end of the connector.

11. The removable cable pulling assembly of claim 1 , wherein the strength layer is crimped to the fiber optic connector.

12. A removable cable pulling assembly comprising:
a removable enclosure adapted for enclosing an end of a fiber optic cable and a fiber optic connector positioned at the end of the fiber optic cable, the fiber optic connector having an axial end, 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 and a first end portion; 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 structurally identical to the removable first member and being in removable snap-fit engagement with the removable first member and being separable from the removable first member, the removable second member being kinematically independent from the removable first member upon separation from the removable first member, and 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; 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 and the second blind cavities;

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 by engagement of the first end portion of the first blind cavity with the axial end of the connector.

13. The removable cable pulling assembly of claim 12 , wherein the longitudinal surface of each of the first and second bodies includes a plurality of alignment guides that extends outwardly from the longitudinal surfaces of the first and second bodies.

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

15. The removable cable pulling assembly of claim 12 , 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.

16. The removable cable pulling assembly of claim 12 , wherein at least one of the removable first and second members is translucent.

17. The removable cable pulling assembly of claim 12 , wherein the second blind cavity of the second body of the removable second member includes a second end portion and wherein the removable enclosure is further adapted to transfer the tensile force applied to the removable enclosure to the strength layer of the fiber optic cable by engagement of the second end portion of the second blind cavity with the axial end of the connector.

18. The removable cable pulling assembly of claim 12 , wherein the strength layer is crimped to the fiber optic connector.

19. A cable pulling assembly comprising:
a fiber optic cable having an end and a strength layer;
a connector engaged to the end of the fiber optic cable, the strength layer being crimped to the connector; and
a removable enclosure enclosing the connector of the fiber optic cable, the removable enclosure including:
a cavity including an end portion;
a removable first member defining a first portion of the cavity, the first portion of the cavity being adapted and contoured to removably engage a portion of the connector of the fiber optic cable; and
a removable s
