Crimp for an optical cable connector

1. A one-piece crimp for an optical cable connector, the one-piece crimp comprising:

a hollow body extending from a first open end to a second open end;

a first crushable crimp tube adjoining the first open end;

a second crushable crimp tube adjoining the second open end;

an enlarged portion extending between the first crushable crimp tube and the second crushable crimp tube, the enlarged portion having a dimension greater than that of the crushable crimp tubes; and

a recess on a periphery of the enlarged portion, wherein the recess is an encircling groove of rectangular-channel cross section.

2. The one-piece crimp of claim 1 , wherein the hollow body is cylindrical.

3. The one-piece crimp of claim 1 , wherein the first and the second crushable crimp tubes are each cylindrical.

4. The one-piece crimp of claim 3 , wherein the first and the second crushable crimp tubes are each of a same diameter.

5. The one-piece crimp of claim 4 , wherein the first and the second crushable crimp tubes are each of a same length.

6. The one-piece crimp of claim 1 , wherein the recess is positioned nearer to the second crushable crimp tube than the first crushable crimp tube.

7. The one-piece crimp of claim 1 , wherein the first crushable crimp tube is configured for crimping onto a spigot of the optical cable connector.

8. The one-piece crimp of claim 1 , wherein the first crushable crimp tube is further configured for crimping reinforcing fibers of an optical cable to the spigot of the optical cable connector.

9. The one-piece crimp of claim 1 , wherein the second crushable crimp tube is configured for crimping onto an optical cable.

10. The one-piece crimp of claim 1 , wherein the recess is configured for engagement by a closure housing.

11. The one-piece crimp of claim 1 , wherein the hollow body is configured to receive an optical cable.

12. A method of securing an optical cable to an optical cable connector, the method comprising:

providing the optical cable;

providing the optical cable connector;

providing a one-piece crimp including:

a hollow body extending from a first open end to a second open end;

a first crushable crimp tube adjoining the first open end;

a second crushable crimp tube adjoining the second open end;

an enlarged portion extending between the first crushable crimp tube and the second crushable crimp tube; and

a recess on a periphery of the enlarged portion;

inserting the optical cable through the hollow body so that the optical cable protrudes at the first open end and the second open end; and

inserting the one-piece crimp into an aperture of a closure housing so that a part of the closure housing engages the recess of the one-piece crimp so as to prevent relative movement between the one-piece crimp and the closure housing.

13. The method of claim 12 , further comprising advancing the one-piece crimp so that the first crushable crimp tube overlies a spigot of the optical cable connector.

14. The method of claim 13 , further comprising crimping the first crushable crimp tube onto the spigot so as to retain the one-piece crimp on the spigot.

15. The method of claim 14 , further comprising:

prior to crimping the first crushable crimp tube onto the spigot:

removing a jacket of the optical cable to expose a core and reinforcement fibers thereof;

inserting the core into the spigot of the optical cable connector; and

arranging the reinforcement fibers about the spigot.

16. The method of claim 15 , further comprising crimping the second crushable crimp tube onto an exterior of the optical cable.

17. An optical cable connector assembly comprising:

a crimp including:

a hollow body extending from a first open end to a second open end;

a first crushable crimp tube adjoining the first open end;

a second crushable crimp tube adjoining the second open end;

an enlarged portion extending between the first crushable crimp tube and the second crushable crimp tube; and

a recess on a periphery of the enlarged portion;

an optical cable including a jacket, a core, and reinforcement fibers; and

an optical cable connector including a spigot and a closure housing;

wherein the reinforcement fibers are arranged about the spigot;

wherein the first crushable crimp tube overlies and is crimped to the reinforcement fibers and the spigot and thereby retains the reinforcement fibers;

wherein the second crushable crimp tube is crimped onto an exterior of the jacket of the optical cable;

wherein an aperture of the closure housing receives the crimp; and

wherein a part of the closure housing engages the recess of the crimp and thereby prevents relative movement between the crimp and the closure housing.
