Abstract

An apparatus includes a backshell, the backshell having a shell defining an interior space, the interior space configured to encase a portion of a plurality of core cables between an entry component and a connector body in a steel wire armored (SWA) cable, wherein the portion represents an excess amount of the core cables when the SWA cable is uncoiled.

Claims

1. A backshell comprising:

a shell defining an interior space, the interior space configured to encase a portion of a plurality of core cables between an entry component and a connector body in a steel wire armored (SWA) cable, wherein the portion represents an excess amount of the core cables when the SWA cable is uncoiled, and wherein the shell is provided between a cable gland assembly and a connection cap to encompass and accommodate the excess amount of the core cables.

2. The backshell of claim 1, wherein the excess amount of the core cables is reduced when the SWA cable is coiled.

3. The backshell of claim 1, wherein the excess amount of the core cables is increased when the SWA cable is uncoiled.

4. The backshell of claim 1, wherein a length of the backshell is less than a length of the core cables between the cable gland assembly and the connection cap.

5. The backshell of claim 1, wherein the excess amount of the core cables is determined based on an overall length of the core cables.

6. The backshell of claim 1, wherein the excess amount of the core cables is determined based on an overall length of the SWA cable.

7. The backshell of claim 1, wherein a length of the backshell is determined based on a diameter of an inside of the backshell.

8. A steel wire armored (SWA) cable comprising:

a plurality of core cables configured to transmit a signal; and

a backshell comprising a shell defining an interior space, the interior space configured to encase a portion of the plurality of core cables between an entry component and a connector body in the SWA cable, wherein the portion represents an excess amount of the core cables when the SWA cable is uncoiled, and wherein the shell is provided between a cable gland assembly and a connection cap to encompass and accommodate the excess amount of the core cables.

9. The SWA cable of claim 8, wherein the excess amount of the core cables is reduced when the SWA cable is coiled.

10. The SWA cable of claim 8, wherein the excess amount of the core cables is increased when the SWA cable is uncoiled.

11. The SWA cable of claim 8, wherein a length of the backshell is less than a length of the core cables between the cable gland assembly and the connection cap.

12. The SWA cable of claim 8, wherein the excess amount of the core cables is determined based on an overall length of the core cable.

13. The SWA cable of claim 8, wherein the excess amount of the core cables is determined based on an overall length of the SWA cable.

14. The SWA cable of claim 8, wherein a length of the backshell is determined based on a diameter of an inside of the backshell.

15. A method comprising:

coiling a steel wire armored (SWA) cable having a plurality of core cables, wherein the coiling of the SWA cable causes a reduction in an excess amount of the plurality of core cables disposed in an interior space of a backshell coupled to the SWA cable; and

uncoiling the SWA cable, wherein the uncoiling of the SWA cable causes the excess amount of the core cables to increase in the interior space of the backshell, and wherein the backshell is provided between a cable gland assembly and a connection cap to encompass and accommodate the excess amount of the core cables.

16. The method of claim 15, wherein a length of the backshell is less than a length of the core cables between the cable gland assembly and the connection cap.

17. The method of claim 15, wherein the core cables have a different bending radius than the SWA cable when the SWA cable is coiled.

18. The method of claim 15, wherein the excess amount of the core cables is determined based on an overall length of the core cables.

19. The method of claim 15, wherein the excess amount of the core cables is determined based on a maximum amount of bending in the SWA cable.

20. The method of claim 15, wherein a length of the backshell is determined based on a diameter of the interior space of the backshell.
