[0029] While the present disclosure will be fully described with reference to the accompanying drawings that contain preferred embodiments of the present disclosure, it should be understood before this description that one of ordinary skill in the art may modify the present disclosure as described herein while still achieving the technical benefits of the present disclosure.

[0032] According to another general inventive concept of the present disclosure, a protective cap for a cable terminal is provided, wherein the cable terminal is mounted on a back cover of a connector, and the back cover has a second cylinder, wherein the protective cap includes a first cylinder and a protrusion protruding radially outward at an insertion end of the first cylinder, the protrusion being able to slide in an axial groove opened on the side wall of the cylinder of the back cover so that the first cylinder is inserted into the second cylinder of the back cover, and the first cylinder inserted into the second cylinder is able to rotate in the second cylinder so that the protrusion can be rotated in a first direction to a locked position, in which the protrusion interferes with a stop protruding radially inward from an inner surface of the side wall of the back cover to prevent the protective cap from detaching from the back cover in an axial direction.

[0033] According to yet another general inventive concept of the present disclosure, a cable assembly is provided. The cable assembly includes a cable terminal and the protection assembly as described above.

Figure 6 1 is a schematic structural diagram of a protective cap 10 and a protective cover 20 (or a back cover 20' of a connector) of a protective assembly for a cable terminal 30 according to an exemplary embodiment of the present disclosure before assembly. Figure 7 1 is a structural schematic diagram of a protective cap 10 and a protective cover 20 (or a back cover 20 ′ of a connector) of a protective assembly for a cable terminal 30 according to an exemplary embodiment of the present disclosure during assembly. Figure 8 yes Figure 1 A schematic cross-sectional view of a protection assembly for a cable terminal 30 is shown.

[0035] like Figures 1 to 8As shown, a protective assembly for a cable terminal 30 according to an exemplary embodiment of the present disclosure includes a protective cap 10 and a protective cover 20 that are sleeved on the cable terminal 30. The protective cap 10 includes a first cylindrical body 11 and a protrusion 12 that protrudes radially outward from the insertion end of the first cylindrical body 11. The protective cover 20 includes a second cylindrical body 21, and an axial groove 24 is defined in the side wall of the second cylindrical body 21. The axial groove 24 extends in a direction parallel to the central axis of the second cylindrical body 21. The protective cover 20 also includes a stopper 23 that protrudes radially inward from the inner surface of the side wall of the second cylindrical body 21. The protrusion 12 can slide in the axial groove 24 so that the insertion end of the first cylinder 11 is inserted into the second cylinder 21, and the first cylinder 11 inserted into the second cylinder 21 can be rotated in the second cylinder 21 along the first direction to a locked position. In this locked position, the protrusion 12 on the protective cap 10 interferes with the stopper 23 in the protective cover 20 in the axial direction, thereby preventing the protective cap 10 from detaching from the protective cover 20 in the axial direction. During assembly, first align the protrusion 12 on the protective cap 10 with the circumferential groove 24 in the protective cover 20, and then insert the insertion end of the protective cap 10 into the protective cover 20. When inserted into place, the protrusion 12 is located on the side of the stopper 23 on the protective cover 20 away from the insertion end of the protective cover 20 in the axial direction. Then, the first cylinder 11 is rotated relative to the second cylinder 21 so that the protrusion 12 rotates to a position corresponding to the stopper 23 in the axial direction, thereby causing the protrusion 12 to interfere with the stopper 23 in the axial direction. During the rotation process, the protrusion 12 is squeezed and deformed by the side wall of the protective cover 20. When the protrusion 12 rotates to a position corresponding to the stopper 23 in the axial direction, the protective cap 10 can abut against the protective cover 20 in the radial direction. In the axial direction, due to the interference between the protrusion 12 and the stopper 23, the protective cap 10 can be effectively prevented from detaching from the protective cover 20 in the axial direction. According to the embodiment of the present disclosure, the protection assembly can improve the holding force of the protection assembly by rotating the protrusion 12 of the protective cap 10 to a locked position to interfere with the stop portion 23 on the protective cover 20, thereby better protecting the shielding ring on the cable terminal to prevent damage to the shielding ring due to improper transportation conditions or transportation methods during the transportation of the cable. In addition, the protection assembly has a simple structure, is easy to manufacture, easy to operate, and is reusable. In addition, since the protrusion 12 and the stop portion 23 are both located inside the second cylinder 21, it is not easy to cause the protrusion 12 and the stop portion 23 to detach when it falls, thereby causing the protective cap 10 to detach from the protective cover 20.When the protection assembly is no longer needed, the first cylinder 11 can be rotated in a direction opposite to the first direction so that the protrusion 12 on the first cylinder 11 is separated from the interference portion 23 and rotated to a position aligned with the axial groove 24. Then, the protrusion 12 is slid along the axial groove 24 to separate the protective cap 10 from the protective cover 20 to remove the protective cap 10.

[0036] In some embodiments, as Figures 1 to 3 、 Figure 8 As shown, the protrusion 12 is separated from the side wall of the first cylinder 11 via the notch 15 in the circumferential direction of the first cylinder 11, and the side wall portion of the first cylinder 11 where the protrusion 12 is located is inclined away from the central axis of the first cylinder 11 in the direction toward the insertion end of the first cylinder 11, so as to prevent damage to the shielding ring 40 on the cable terminal during the assembly of the protective cap 10 and the protective cover 20, and at the same time, the protrusion 12 can be elastically deformed in the radial direction when the first cylinder 11 is rotated in the second cylinder 21, so that the protrusion 12 of the first cylinder 11 can be easily rotated to a position corresponding to the stop portion 23 of the second cylinder 21.

[0037] In some embodiments, as Figure 4 、 Figure 5 and Figure 8 As shown, the second cylinder 21 is formed with a cantilever 22, which is inclined toward the insertion end of the second cylinder 21 and toward the central axis of the second cylinder 21, and a stopper 23 is formed at the free end of the cantilever 22. By forming the stopper 23 at the free end of the cantilever 22, the holding force of the protective assembly can be further improved.

[0038] In some embodiments, as Figure 2 and Figure 3 As shown, the number of the protrusions 12 of the protective cap 10 is two, and the two protrusions 12 are arranged at equal intervals along the circumference of the first cylinder 11, thereby improving the connection reliability between the protective cap 10 and the protective cover 20, and making the overall force on the protective cap 10 and the protective cover 20 more uniform in the circumferential direction. It should be noted that in some other embodiments of the present disclosure, the number of protrusions can also be one, three or other values. The specific value should be designed according to the specific situation, and the present disclosure does not limit this. In addition, although in Figure 2 and Figure 3 In the illustrated embodiment, the two protrusions 12 are arranged at equal intervals along the circumference of the first cylinder 11 . However, in other embodiments of the present disclosure, the protrusions 12 may also be arranged at unequal intervals along the circumference of the first cylinder 11 .

[0039] In some embodiments, as Figures 1 to 3 、 Figure 8As shown, the outer surface of the first cylinder 11 is provided with a flange 13 protruding radially outward, which extends at least partially along the circumference of the first cylinder 11, and is configured to prevent the first cylinder 11 from continuing to move in the insertion direction after being inserted into the appropriate position of the second cylinder 21. At this "appropriate position", the protrusion 12 can be rotated to a position corresponding to the stop 23, so as to interfere with the stop 23.

[0040] In some embodiments, as shown in Figures 1 to 3 , the protective cap 10 is also provided with a blocking portion 14, which is configured to prevent the first cylinder 11 from continuing to rotate in the first direction after being rotated to the locked position in the first direction. In this embodiment, the blocking portion 14 is provided on the protective cap 10, however, it should be noted that in other embodiments of the present disclosure, the stop portion can also be provided on the protective cover 20, for example, the stop portion can be provided as a structure protruding radially inward on the inner side wall of the second cylinder 21 of the protective cover 20, which can interfere with the protrusion protruding radially outward on the first cylinder of the protective cap 10 when the first cylinder 11 is rotated to the locked position in the first direction, thereby preventing the first cylinder 11 from continuing to rotate in the first direction, to ensure the connection reliability of the protective cap 10 and the protective cover 20.

[0041] In some embodiments, as shown in Figures 1 to 3 , the protective cap 10 also has a foolproof mechanism configured to prevent the first cylinder 11 from being inserted into the second cylinder 21 when the protrusion 12 is not aligned with the axial slot 24, thereby reducing the risk of misoperation and improving work efficiency.

[0042] In some embodiments, as shown in Figure 2 , Figure 3 and Figure 6 , the blocking portion 14 is provided on the flange 13 and serves as a foolproof mechanism. That is, the blocking portion 14 has the functions of both stopping and foolproofing, which can reduce costs and is simple to manufacture. However, it should be noted that in other embodiments of the present disclosure, the stop portion and the foolproof mechanism can also be two separate components.

[0043] In some embodiments, as shown in Figure 2 , Figure 3 and Figure 7 , one side of the axial slot 24 is provided with a guide surface to guide the rotation of the protrusion 12 in the first direction.

[0044] According to another aspect of the present disclosure, a protective cap for a cable terminal 30 is provided. The protective cap may be the protective cap 10 described above. The cable terminal 30 is mounted on a back cover 20' of a connector, the back cover 20' having a second barrel 21. Specifically, the protective cap 10 includes a first barrel 11 and a protrusion 12 protruding radially outward from an insertion end of the first barrel 11. The protrusion 12 is capable of sliding within an axial groove 24 defined in a sidewall of the second barrel 21 of the back cover 20', so that the first barrel 11 is inserted into the second barrel 21 of the back cover 20'. The first barrel 11 inserted into the second barrel 21 is capable of rotating within the second barrel 21, so that the protrusion 12 is capable of rotating in a first direction to a locked position. In this locked position, the protrusion 12 on the protective cap 10 interferes axially with a stopper 23 protruding radially inward from an inner surface of the sidewall of the back cover 20', thereby preventing the protective cap 10 from detaching from the back cover 20' in the axial direction. During assembly, first align the protrusion 12 on the protective cap 10 with the circumferential groove 24 in the back cover 20ʹ, and then insert the insertion end of the protective cap 10 into the back cover 20ʹ. When inserted into place, the protrusion 12 is located on the side of the stop portion 23 on the back cover 20ʹ away from the insertion end of the back cover 20ʹ in the axial direction. Then, the first cylinder 11 is rotated relative to the second cylinder 21 so that the protrusion 12 rotates to a position corresponding to the stop portion 23 in the axial direction, thereby causing the protrusion 12 to interfere with the stop portion 23 in the axial direction. During the rotation process, the protrusion 12 is squeezed and deformed by the side wall of the back cover 20ʹ. When the protrusion 12 rotates to a position corresponding to the stop portion 23 in the axial direction, the protective cap 10 can abut against the back cover 20ʹ in the radial direction. In the axial direction, due to the interference between the protrusion 12 and the stop portion 23, the protective cap 10 can be effectively prevented from detaching from the cover 20ʹ in the axial direction. During cable transportation, the protective cap 10 is assembled with the back cover 20' of the connector on which the cable terminal 30 is mounted. Interference between the protective cap 10 and the stopper 23 on the back cover 20' prevents the protective cap 10 from detaching axially from the back cover 20', thereby effectively protecting the shielding ring 40 on the cable terminal mounted on the connector and preventing damage to the shielding ring due to improper transportation conditions or methods during cable transportation. When the connector needs to be connected to a mating connector, the first barrel 11 can be rotated in a direction opposite to the first direction so that the protrusion 12 on the first barrel 11 separates from the interference portion 23 and rotates to a position aligned with the axial groove 24. The protrusion 12 is then slid along the axial groove 24 to separate the protective cap 10 from the back cover 20'. The mating connector can then be plugged into the connector. The protective cap 10 disclosed herein can be used in conjunction with the back cover 20' of an existing connector for a cable terminal, further reducing manufacturing costs.

[0045] In some embodiments, as Figures 1 to 3 、 Figure 8 As shown, the protrusion 12 is separated from the side wall of the first cylinder 11 via the notch 15 in the circumferential direction of the first cylinder 11, and the side wall portion of the first cylinder 11 where the protrusion 12 is located is inclined away from the central axis of the first cylinder 11 in the direction toward the insertion end of the first cylinder 11, so as to prevent damage to the shielding ring 40 on the cable terminal during the assembly of the protective cap 10 and the protective cover 20ʹ, and at the same time, the protrusion 12 can be elastically deformed in the radial direction when the first cylinder 11 is rotated in the second cylinder 21, so that the protrusion 12 of the first cylinder 11 can be easily rotated to a position corresponding to the stop portion 23 of the second cylinder 21.

[0046] In some embodiments, as Figure 4 、 Figure 5 and Figure 8 As shown, the second cylinder 21 is formed with a cantilever 22, which is inclined toward the insertion end of the second cylinder 21 and toward the central axis of the second cylinder 21, and a stopper 23 is formed at the free end of the cantilever 22. By forming the stopper 23 at the free end of the cantilever 22, the holding force of the protective assembly can be further improved.

[0047] In some embodiments, as Figure 2 and Figure 3 As shown, the number of the protrusions 12 of the protective cap 10 is two, and the two protrusions 12 are arranged at equal intervals along the circumference of the first cylinder 11, thereby improving the connection reliability between the protective cap 10 and the back cover, and making the overall force on the protective cap 10 and the back cover more uniform in the circumferential direction. It should be noted that in some other embodiments of the present disclosure, the number of protrusions can also be one, three or other values. The specific value should be designed according to the specific situation, and the present disclosure does not limit this. In addition, although in Figure 2 and Figure 3 In the illustrated embodiment, the two protrusions 12 are arranged at equal intervals along the circumference of the first cylinder 11 . However, in other embodiments of the present disclosure, the protrusions 12 may also be arranged at unequal intervals along the circumference of the first cylinder 11 .

[0048] In some embodiments, as Figures 1 to 3 、 Figure 8 As shown, a radially outwardly protruding flange 13 is provided on the outer surface of the first cylindrical body 11. The flange 13 extends at least partially along the circumference of the first cylindrical body 11. The flange 13 is configured to prevent the first cylindrical body 11 from further moving in the insertion direction after the first cylindrical body 11 is inserted into the appropriate position of the second cylindrical body 21. In this "appropriate position", the protrusion 12 can rotate to a position corresponding to the stopper 23, thereby interfering with the stopper 23.

[0049] In some embodiments, as Figures 1 to 3 As shown, the protective cap 10 is further provided with a blocking portion 14, which is configured to prevent the first cylinder 11 from continuing to rotate in the first direction after rotating in the first direction to the locked position. In this embodiment, the blocking portion 14 is provided on the protective cap 10. However, it should be noted that in some other embodiments of the present disclosure, the blocking portion may also be provided on the back cover. For example, the blocking portion may be provided as a structure protruding radially inward on the inner side wall of the second cylinder 21 of the back cover. When the first cylinder 11 is rotated in the first direction to the locked position, the blocking portion may interfere with the radially outward protrusion on the first cylinder of the protective cap 10, thereby preventing the first cylinder 11 from continuing to rotate in the first direction, so as to ensure the reliability of the connection between the protective cap 10 and the back cover.

[0050] In some embodiments, as Figures 1 to 3 As shown, the protective cap 10 also has an anti-foolproofing mechanism, which is configured to prevent the first cylinder 11 from being inserted into the second cylinder 21 when the protrusion 12 is not aligned with the axial groove 24, thereby reducing erroneous operation and improving work efficiency.

[0051] In some embodiments, as Figure 2 、 Figure 3 and Figure 6 As shown, the blocking portion 14 is provided on the flange 13 and serves as an anti-foolproofing mechanism. In other words, the blocking portion 14 has both the stopping and anti-foolproofing functions, which can reduce costs and simplify manufacturing. However, it should be noted that in some other embodiments of the present disclosure, the blocking portion and the anti-foolproofing mechanism can also be two separate components.

[0052] According to yet another aspect of the present disclosure, a cable assembly is provided. The cable assembly includes a cable terminal and the protection assembly for the cable terminal as described above.

[0053] According to the protective cap, protective assembly, and cable assembly for a cable terminal described in the various embodiments of the present disclosure, the protrusion on the protective cap is rotated to a locked position to interfere with a stop on the protective cover of the protective assembly or a stop on the back cover of the connector on which the cable terminal is mounted, thereby improving the retention force of the protective assembly. The protective assembly is simple in structure, easy to manufacture, convenient to operate, and reusable. In addition, because the protrusion and the stop are both located inside the second barrel of the protective cover, it is not easy to cause the protrusion and the stop to separate due to misoperation or falling, thereby causing the protective cap to separate from the protective cover.

[0054] Those skilled in the art will appreciate that the embodiments described above are exemplary and that they may be improved upon. The structures described in the various embodiments may be freely combined without causing any conflict in structure or principle.

[0055] Although the present disclosure is described in conjunction with the accompanying drawings, the embodiments disclosed in the drawings are intended to exemplify the preferred embodiments of the present disclosure and should not be construed as limiting the present disclosure.

[0056] Although some embodiments of the present general inventive concept have been shown and described, it will be appreciated by those skilled in the art that changes may be made to these embodiments without departing from the principles and spirit of the present general inventive concept, the scope of which is defined in the claims and their equivalents.

[0057] It should be noted that the word "comprising" does not exclude other elements or steps, and the word "a" or "an" does not exclude a plurality. In addition, any element reference numerals in the claims should not be construed as limiting the scope of the disclosure.
