a phase block that is positioned between the terminal box and the terminal box clamp and is mounted to the terminal box and the phase cable, wherein the phase cable extends through the phase block and the phase block is spaced apart from the terminal box clamp.

7. The axle assembly of claim 6 wherein the support bracket is cantilevered from the terminal box, and the terminal box clamp is mounted to the support bracket and is spaced apart from the terminal box.

8. The axle assembly of claim 6 wherein the phase block is spaced apart from the terminal box cover.

9. The axle assembly of claim 6 wherein the phase block defines an opening, a seal is received in the opening, and the seal extends around and receives the phase cable.

10. The axle assembly of claim 9 wherein the phase cable is substantially linear between the terminal box and the terminal box clamp.

11. The axle assembly of claim 9 further comprising a push nut that is received in the opening, wherein the push nut inhibits axial movement of the seal away from the terminal box.

12. The axle assembly of claim 9 wherein the opening is tapered such that the opening extends further from the phase cable in an axial direction that extends away from the terminal box and toward the terminal box clamp.

13. The axle assembly of claim 9 wherein a phase block clamp is disposed in the opening and extends continuously around and contacts the phase cable.

14. The axle assembly of claim 13 wherein the phase block clamp extends into the terminal box.

15. An axle assembly comprising:

an electric motor module;

a terminal box that facilitates mounting of a phase cable that is electrically connected to the electric motor module;

a terminal box cover that is mounted to the terminal box and that has a support bracket;

a terminal box clamp that is mounted to the support bracket, wherein the phase cable is secured to the support bracket with the terminal box clamp; and

a phase block that is mounted to a side of the terminal box that faces toward the terminal box clamp and to the phase cable, wherein the phase cable extends through the phase block and the phase block is spaced apart from the terminal box clamp.

16. The axle assembly of claim 15 wherein the phase block is positioned between the terminal box and the terminal box clamp.

17. An axle assembly comprising:

a differential carrier that rotatably supports a differential;

a cover;

an electric motor module that provides torque to the differential and is disposed between the differential carrier and the cover;

a terminal box that extends from the cover, wherein the terminal box facilitates electrically connecting the electric motor module to a phase cable;

a terminal box cover that is mounted to the terminal box and that has a support bracket;

a terminal box clamp that is mounted to the support bracket, wherein the phase cable is secured to the support bracket with the terminal box clamp, and

a phase block that is mounted to the terminal box and the phase cable, wherein the phase cable extends through the phase block and the phase block is spaced apart from the terminal box cover and the terminal box clamp.

18. The axle assembly of claim 17 wherein a rotor of the electric motor module is rotatable about a first axis and the cover is disposed substantially perpendicular to the first axis.

19. The axle assembly of claim 18 wherein at least a portion of the terminal box cover is disposed further from the first axis than the electric motor module.

20. The axle assembly of claim 18 wherein the cover has a through hole that extends around the first axis and the through hole receives at least a portion of a drive pinion that transmits torque between the electric motor module and the differential, and the through hole receives at least a portion of a planetary gear set that transmits torque between the electric motor module and the drive pinion.
