The protective cap includes a first cylinder body and a protrusion protruding radially and outwardly from an insertion end of the first cylinder body. The protective cover includes a stop and a second cylinder body having a side wall with an axial groove. The stop protrudes radially and inwardly from an inner surface of the side wall of the second cylinder body. The protrusion is slidable in the axial groove such that the insertion end of the first cylinder body is inserted into the second cylinder body. The first cylinder body is rotatable within the second cylinder body into a locking position where the protrusion interferes with the stop to prevent the protective cap from disengaging from the protective cover. The protective cap and the protective cover are sleeved on the cable termination. ## Claims ### Claim 1 A protective assembly for a cable termination, comprising: a protective cap including a first cylinder body and a protrusion protruding radially and outwardly from an insertion end of the first cylinder body; and a protective cover including a stop and a second cylinder body having a side wall with an axial groove, the stop protrudes radially and inwardly from an inner surface of the side wall of the second cylinder body, the protrusion is slidable in the axial groove such that the insertion end of the first cylinder body is inserted into the second cylinder body, the first cylinder body is rotatable in a first direction within the second cylinder body into a locking position where the protrusion interferes with the stop to prevent the protective cap from disengaging from the protective cover in an axial direction, the protective cap and the protective cover are sleeved on the cable termination. ### Claim 2 (depends on 1) The protective assembly of claim 1, wherein the protrusion is separated from a side wall of the first cylinder body along a circumferential direction of the first cylinder body via a notch, a portion of the side wall of the first cylinder body where the protrusion is located is inclined away from a central axis of the first cylinder body in a direction toward the insertion end of the first cylinder body. ### Claim 3 (depends on 2) The protective assembly of claim 2, wherein the second cylinder body has a cantilever inclined toward an insertion end of the second cylinder body and toward a central axis of the second cylinder body, the stop is formed at a free end of the cantilever. ### Claim 4 (depends on 1) The protective assembly of claim 1, wherein the protective cap has a plurality of protrusions, the protrusions are arranged at intervals along a circumferential direction of the first cylinder body. ### Claim 5 (depends on 1) The protective assembly of claim 1, wherein an outer surface of the first cylinder body has a flange protruding radially and outwardly, the flange extends at least partially along a circumferential direction of the first cylinder body and prevents the first cylinder body from continuing to move along an insertion direction relative to the second cylinder body after being inserted into a rotatable position of the second cylinder body. ### Claim 6 (depends on 5) The protective assembly of claim 5, wherein the protective cap has a barrier preventing the first cylinder body from continuing to rotate along the first direction after rotating into the locking position. ### Claim 7 (depends on 6) The protective assembly of claim 6, wherein the protective cap has a mistake-proof mechanism preventing the first cylinder body from being inserted into the second cylinder body when the protrusion is not aligned with the axial groove. ### Claim 8 (depends on 7) The protective assembly of claim 7, wherein the barrier is provided on the flange. ### Claim 9 (depends on 8) The protective assembly of claim 8, wherein the barrier serves as the mistake-proof mechanism. ### Claim 10 (depends on 1) The protective assembly of claim 1, wherein a guiding surface is provided on a side of the axial groove to guide the protrusion to rotate along the first direction. ### Claim 11 A protective cap for a cable termination, comprising: a first cylinder body and a protrusion protruding radially and outwardly from an insertion end of the first cylinder body, the cable termination is mounted on a back cover of a connector, the back cover has a second cylinder body, the protrusion is slidable in an axial groove in a side wall of the second cylinder body such that the first cylinder body is inserted into the second cylinder body, the first cylinder body is rotatable within the second cylinder body such that the protrusion is rotatable in a first direction into a locking position where the protrusion interferes with a stop protruding radially and inwardly from an inner surface of a side wall of the back cover to prevent the protective cap from disengaging from the back cover in an axial direction. ### Claim 12 (depends on 11) The protective cap of claim 11, wherein the protrusion is separated from the side wall of the first cylinder body along a circumferential direction of the first cylinder body via a notch. ### Claim 13 (depends on 11) The protective cap of claim 11, wherein a portion of the side wall of the first cylinder body where the protrusion is located is inclined away from a central axis of the first cylinder body in a direction toward the insertion end of the first cylinder body. ### Claim 14 (depends on 11) The protective cap of claim 11, wherein the protective cap has a plurality of protrusions. ### Claim 15 (depends on 14) The protective cap of claim 14, wherein the protrusions are arranged at intervals along a circumferential direction of the first cylinder body. ### Claim 16 (depends on 11) The protective cap of claim 11, wherein the protective cap has a barrier preventing the first cylinder body from continuing to rotate along the first direction after rotating along the first direction into the locking position. ### Claim 17 (depends on 11) The protective cap of claim 11, wherein the protective cap has a mistake-proof mechanism preventing the first cylinder body from being inserted into the second cylinder body when the protrusion is not aligned with the axial groove. ### Claim 18 A cable assembly, comprising: a cable termination; and a protective assembly including a protective cap and a protective cover, the protective cap includes a first cylinder body and a protrusion protruding radially and outwardly from an insertion end of the first cylinder body, the protective cover includes a stop and a second cylinder body having a side wall with an axial groove, the stop protrudes radially and inwardly from an inner surface of the side wall of the second cylinder body, the protrusion is slidable in the axial groove such that the insertion end of the first cylinder body is inserted into the second cylinder body, the first cylinder body is rotatable in a first direction within the second cylinder body into a locking position where the protrusion interferes with the stop to prevent the protective cap from disengaging from the protective cover in an axial direction, the protective cap and the protective cover are sleeved on the cable termination.
