a second end; a radially outward facing surface; and a radial surface that traverses the radially outward facing surface; and a shroud at least partially surrounding the terminal, the shroud including: a third end arranged proximate to the first end; a fourth end forming a first flange; a first hole forming a radially inward facing surface, wherein the terminal is arranged in the first hole and the radially inward facing surface is operatively arranged to engage the radially outward facing surface; and a second flange extending radially inward in a first radial direction from the radially inward facing surface, the second flange operatively arranged to engage the radial surface. ### Claim 2 (depends on 1) The high current terminal assembly as recited in claim 1, wherein: the radially outward facing surface comprises a first groove proximate the first end; the radially inward facing surface comprises a protrusion proximate the third end and extending radially inward in the first radial direction therefrom; and the protrusion is operatively arranged to engage the first groove to connect the shroud to the terminal. ### Claim 3 (depends on 2) The high current terminal assembly as recited in claim 2, wherein the engagement of the protrusion with the first groove prevents axial displacement of the shroud with respect to the terminal in an axial direction. ### Claim 4 (depends on 2) The high current terminal assembly as recited in claim 2, wherein the protrusion forms a frusto-conical surface extending in the first radial direction in the axial direction. ### Claim 5 (depends on 1) The high current terminal assembly as recited in claim 1, wherein: the radially outward facing surface further comprises a groove; and, a first seal is arranged in the groove and operatively arranged to engage the radially inward facing surface to fluidly seal the terminal and the shroud. ### Claim 6 (depends on 1) The high current terminal assembly as recited in claim 1, wherein the first flange comprises a second hole. ### Claim 7 (depends on 6) The high current terminal assembly as recited in claim 6, further comprising a bushing arranged in the second hole, wherein: the bushing comprises a first material having a first hardness; the shroud comprises a second material having a second hardness; and the first hardness is greater than the second hardness. ### Claim 8 (depends on 2) The high current terminal assembly as recited in claim 2, wherein the terminal further comprises an axial surface, the axial surface operatively arranged to engage the second flange to prevent displacement of the shroud with respect to the terminal in an axial direction. ### Claim 9 (depends on 1) The high current terminal assembly as recited in claim 1, wherein: the radially outward facing surface further comprises a groove; and a seal is arranged in the groove and operatively arranged to engage a hole of an inverter housing to fluidly seal the shroud and the inverter housing. ### Claim 10 (depends on 1) The high current terminal assembly as recited in claim 1, wherein the terminal further comprises: a second hole arranged proximate the first end; and a third hole arranged proximate the second end. ### Claim 11 A high current terminal assembly, comprising: a shroud, comprising: a first end; a second end forming a first flange; a first hole extending at least partially from the first end to the second end, the first hole forming a radially inward facing surface; and a second flange arranged between the first end and the second end, the second flange extending radially inward in a first radial direction from the radially inward facing surface; a portion extending radially from the first flange, the portion including a second hole arranged parallel to the first hole. ### Claim 12 (depends on 11) The high current terminal assembly as recited in claim 11, wherein the shroud further comprises a protrusion arranged proximate the first end, the protrusion extending from the radially inward facing surface in the first radial direction. ### Claim 13 (depends on 11) The high current terminal assembly as recited in claim 11, wherein the radially inward facing surface forms a partial circle ending at a first axial surface. ### Claim 14 (depends on 12) The high current terminal assembly as recited in claim 12, further comprising a terminal operatively arranged to engage the first hole, the terminal comprising: a third end having a groove, the groove operatively arranged to engage the protrusion to prevent displacement of the terminal with respect to the shroud in a first axial direction; a fourth end; a radially outward facing surface operatively arranged at least proximate to the radially inward facing surface; and a second axial surface operatively arranged to engage second flange to prevent displacement of the terminal with respect to the shroud in a second axial direction, opposite the first axial direction. ### Claim 15 (depends on 11) The high current terminal assembly as recited in claim 11, further comprising a bushing arranged in the second hole, wherein: the bushing comprises a first material having a first hardness; the shroud comprises a second material having a second hardness; and the first hardness is greater than the second hardness. ### Claim 16 A high current terminal assembly, comprising: a terminal, comprising: a first end including a groove; a second end; a radially outward facing surface; a planar radial surface that traverses the radially outward facing surface, the planar radial surface extending from the first end towards the second end; and an axial surface arranged between the first end and the second end, the axial surface connected and being arranged perpendicular to the radial surface. ### Claim 17 (depends on 16) The high current terminal assembly as recited in claim 16, wherein the terminal further comprises: a second hole arranged proximate the first end, the second hole extending in a radial direction through the planar radial surface; and a third hole extending axially from the second end. ### Claim 18 (depends on 16) The high current terminal assembly as recited in claim 16, further comprising a shroud operatively arranged to at least partially surround the terminal, the shroud comprising: a third end; a fourth end forming a first flange; a first hole forming a radially inward facing surface, the terminal arranged in the first hole; a second flange arranged between the first end and the second end, the second flange extending radially inward from the radially inward facing surface and operatively arranged to engage the axial surface to prevent displacement of the terminal with respect to the shroud in a first axial direction; and a protrusion extending radially inward from the radially inward facing surface and operatively arranged to engage the groove to prevent displacement of the terminal with respect to the shroud in a second axial direction, opposite the first axial direction.
