DETAILED DESCRIPTION

[0044] The utility model will be further described in detail in combination with embodiments.

[0048] Referring to the accompanying Figure 1 , the accompanying Figure 2 , and the accompanying Figure 3 , the cable assembly comprises a shell, a limiting sheet 5 and a cable module 3 inserted in the shell.

[0049] The shell comprises an outer shell 1 and a middle shell 2. Referring to the attached Figure 4 , the front end of the outer shell 1 is used to guide the outer shell of the adapter connector when the adapter connector is inserted, and this part of the structure is prior art and will not be described again. The end face of the rear end of the outer shell 1 is provided with a mounting cavity 11 for mounting the middle shell 2 from the rear to the front, referring to the attached Figure 5 , after the middle shell 2 is mounted into the mounting cavity 11, the rear end face of the middle shell 2 is aligned with the rear end face of the outer shell 1. A plurality of guide strips 13 extending in the front-rear direction are provided on the cavity side wall of the mounting cavity 11, and a guide groove 23 extending in the front-rear direction and used for guiding the guide strips 13 is provided on the side wall of the middle shell 2. The cooperation of the guide groove 23 and the guide strips 13 can improve the convenience of mounting the middle shell 2 into the outer shell 1. Figure 6 Figure 19 A anti-falling structure is arranged between the outer shell 1 and the middle shell 2 for limiting the middle shell 2 in the front-rear direction to avoid the middle shell 2 from falling out of the outer shell 11. The anti-falling structure comprises an anti-falling piece 4, and one-to-one corresponding anti-falling holes 6 are arranged on the middle shell 2 and the outer shell 1, referring to the attached and the attached

[0050] The anti-falling piece 4 is a comb-shaped structure, comprising a base 41 and a tooth 42 arranged on the same side of the width direction of the base 41 and along the length direction of the base 41, referring to the attached Figure 15 , the tooth 42 of the anti-falling piece 4 is first inserted from the outside into the anti-falling hole 6 on the outer shell 1, and after passing through the anti-falling hole 6 on the outer shell 1, it is continuously inserted into the anti-falling hole 6 on the middle shell 2. The base 41 is left on the outside of the outer shell 1, so that the tooth 42 is inserted into the anti-falling hole 6 on the middle shell 2 and the outer shell 1 at the same time, thereby keeping the middle shell 2 stable relative to the outer shell 1 and avoiding the middle shell 2 from falling out of the outer shell 1. Figure 16 Figure 19 Because the cable module 3 is arranged in the middle shell 2 in a staggered manner, the thickness of the side wall of the middle shell 2 is not uniform, so the tooth 42 of the cable tie piece is of a structure with different lengths to adapt to the wall thickness of the middle shell 2. The end of the tooth 42 away from the base 41 is provided with a chamfer, and the hole opening position of the anti-falling hole 6 is also provided with a chamfer to facilitate insertion and assembly. A protrusion is arranged on each tooth 42 for closely cooperating with the hole wall of the jack to prevent the anti-falling piece 4 from falling off the shell.

[0051] The cable module 3 comprises four cable components 31 arranged in a row, referring to the attached , the attached

[0052] , the attached Figure 11 , the attached Figure 12 and the attached Figure 13 The cable module 3 comprises four cable components 31 arranged in a row, referring to the attached Figure 14The cable component 31 comprises a cable body 311, a terminal 312 arranged at one end of the cable body 311, an insulator 313 arranged for insulation between the terminal 312 and a shield 314, and the shield 314 comprising a main body portion surrounding the corresponding terminal 312, a clamping jaw clamping the corresponding cable body 311, and a connecting arm connecting between the main body portion and the clamping jaw, the clamping jaw being located at the rear of the main body portion. The main body portion of the shield 314 is used for electromagnetic shielding of the terminal 312, and the clamping jaw is used for firm connection of the shield 314 with the cable body 311, and the shield 314 can also be grounded with the shield layer of the cable body 311 by clamping the shield layer of the cable body 311 with the clamping jaw.

[0053] The shield 314 comprises a bottom shield sheet 3141 for shielding the terminal 312 in three side directions, and a top shield sheet 3142 for shielding the terminal 312 in the remaining one side direction, the top shield sheet 3142 being fixedly connected with the bottom shield sheet 3141 by welding, and the bottom shield sheet 3141 and the top shield sheet 3142 each have portions corresponding to the main body portion, the connecting arm and the clamping jaw. The bottom shield sheet 3141 comprises three side plates, and a limiting slot 3143 is arranged on the side plate adjacent to the top shield sheet 3142 on the bottom shield sheet 3141, the limiting slot 3143 being a through slot penetrating the corresponding side plate in the wall thickness direction, the limiting slot 3143 being arranged not to penetrate the side edge of the corresponding side plate connected with the top shield sheet 3142, and the side edge of the side plate connected with the top shield sheet 3142 constitutes a supporting portion 3144 for supporting the top shield sheet 3142 at the position corresponding to the limiting slot 3143.

[0054] The cable module 3 further comprises a plastic body 32 connecting the cable components 31 in the row into a whole, the plastic body 32 being injection molded, the plastic body 32 being connected with the cable components 31 at the positions of the clamping jaws and covering the clamping jaws, which on the one hand can prevent the clamping jaws from loosening from the corresponding cable bodies 311, and on the other hand, since the clamping jaws are smaller in size than the main body portion of the shield 314, arranging the plastic body 32 at this position can make the plastic body 32 smaller in size, thereby saving the internal space of the cable assembly.

[0055] Referring to the accompanying drawings Figure 7 , the accompanying drawings Figure 8 , the accompanying drawings Figure 9 , and the accompanying drawings Figure 10The middle shell 2 is provided with an installation cavity 21 for installing the plastic body 32, the installation cavity 21 is a long strip-shaped hole penetrating through the middle shell 2 from front to back, the plastic body 32 is provided with a protruding buckle 321, the cavity side wall of the installation cavity 21 is provided with a clamping hole 22 for clamping and matching with the buckle 321, the clamping hole 22 is a blind hole, the buckle 321 is a wedge-shaped structure and the inclined surface of the wedge-shaped structure is located at the front end of the buckle 321 so that the buckle 321 can be matched with the clamping hole 22 after the plastic body 32 is inserted into the corresponding installation cavity 21 from back to front. Each cable module 3 can be pre-assembled with the middle shell 2 by using the buckle 321 and the clamping hole 22, which is convenient for subsequent overall assembly.

[0056] After each cable module 3 is installed on the middle shell 2, the shielding member 314 of the cable module 3 protrudes forward from the middle shell 2, and a through hole 12 is provided between the front side wall surface of the assembly cavity 11 and the front end of the outer shell 1 for each shielding member 314 to pass through. On the one hand, the through hole 12 can make each shielding member 314 and the terminal 312 protrude to the front end of the outer shell 1, and on the other hand, the through hole 12 can also limit the shielding member 314 and maintain the posture of the shielding member 314.

[0057] Referring to the accompanying drawings Figure 19 and the accompanying drawings Figure 20 The front side wall surface of the assembly cavity 11 and the front end surface of the middle shell 2 leave an installation space for the installation of the limiting piece 5, and the installation space also constitutes the limiting cavity 7. The front side wall surface of the assembly cavity 11 is the front side wall surface of the limiting cavity 7, and the front end surface of the middle shell 2 is the rear side wall surface of the limiting cavity 7.

[0058] The limiting piece 5 is provided with two and is located at both sides in the shell. Referring to the accompanying drawings Figure 17 and the accompanying drawings Figure 18 The limiting piece 5 includes a shell limiting part 51 and a cable limiting part. The shell limiting part 51 is a long strip-shaped structure, and the cable limiting part is located at one side of the width direction of the shell limiting part 51 and arranged along the length direction of the shell limiting part 51. The cable limiting part in the same limiting piece 5 includes a long limiting part 52 and a short limiting part 53 which are alternately arranged along the length direction of the shell limiting part 51. The long limiting part 52 and the short limiting part 53 are arranged in close proximity, so that the corresponding side edge of the limiting piece 5 forms a concave-convex structure, wherein the convex part corresponds to the long limiting part 52 and the concave part corresponds to the short limiting part 53. The end part of the long limiting part 52 and the short limiting part 53 is provided with an opening 54.

[0059] During assembly, after each cable module 3 is installed into the middle housing 2, the shielding member 314 of each cable component 31 in the cable module 3 extends from the front end of the middle housing 2. At this time, the limiting piece 5 is installed on the front side of the middle housing 2. Specifically, the cable components 31 at both ends of the cable component 31 in the same cable module 3 are designated as edge cable components. The end of the cable limiting part on the limiting piece 5 is inserted into the limiting groove 3143 of the corresponding edge cable component. The front and rear side walls of the limiting groove 3143 abut against the front and rear side walls of the corresponding cable limiting part, respectively. The position of the notch 54 corresponds to the position of the support part 3144 on the shielding member 314, thereby using the notch 54 to avoid interference by avoiding the support part 3144. The front and rear side walls of the limiting groove 3143 are provided with protrusions to ensure that the front and rear side walls of the limiting groove 3143 can fit tightly with the cable limiting part and conduct electricity.

[0060] After installing the limiting piece 5, the middle housing 2 is then inserted into the assembly cavity 11 on the outer housing 1, and the anti-detachment piece 4 is used to limit the middle housing 2 from front to back, thus keeping it within the limiting cavity. After the middle housing 2 is installed in place, a limiting cavity 7 is formed between the front end face of the middle housing 2 and the front side wall of the assembly cavity 11, and the housing limiting part 51 of the limiting piece 5 is located within the limiting cavity 7.

[0061] See appendix Figure 19 and attached Figure 20 The housing limiting part 51 is used to cooperate with the front side wall and the rear side wall of the limiting cavity 7 respectively to limit the housing limiting part 51 in the forward and backward directions; the cable limiting part is used to cooperate with the front side wall and the rear side wall of the limiting groove 3143 respectively to limit the cable module 3 in the backward and forward directions.

[0062] The middle shell 2 and the outer shell 1 are generally formed by high-pressure injection molding, which has good surface quality and hard texture, and can provide relatively accurate positioning for the limiting plate 5. The limiting plate 5 and the shielding component 314 are both made of metal plate, which has high strength and hardness. Therefore, they can also provide relatively accurate positioning, reduce the amount of back-and-forth movement of the cable module 3 when subjected to external force, and thus make the overall positioning accuracy higher, ensuring the front-and-back alignment of each cable module 3.

[0063] In addition, since the plastic body 32 in this embodiment no longer serves to cooperate with the limiting piece 5 to limit the cable module 3, the plastic body 32 can reduce its own strength and surface precision requirements, thereby reducing production costs.

[0064] In order to obtain better shielding effect in the embodiment, the cable modules 3 are staggered, so the cable limiting part is divided into a long limiting part 52 and a short limiting part 53, so that the long limiting part 52 and the short limiting part 53 on the same side of the cable assembly can adapt to the positions of the corresponding edge cable components. The same cable module 3 has two edge cable components, and the two edge cable components correspond to the long limiting part 52 in one limiting sheet 5 and the short limiting part 53 in the other limiting sheet 5, respectively.

[0065] In addition to being able to play a limiting role on the cable module 3, the limiting sheet 5 can also conduct the shielding members 314 on the edge cable components in different cable modules 3 to each other to achieve common ground, thereby enhancing the shielding effect of the cable assembly to a first extent.

[0066] In addition, the cable modules 3 in the embodiment can be assembled as a whole on the middle shell 2, and it is not necessary to install each cable component 31 in the cable module 3 one by one, thereby reducing the assembly steps of the cable assembly and improving the assembly efficiency. Since the cross-sectional size of the plastic body 32 of each cable module 3 is larger than that of a single cable component 31, and the size of the mounting cavity 21 on the middle shell 2 for mounting the plastic body 32 is also larger, the alignment during assembly is easier, the assembly difficulty is reduced, and the assembly efficiency is further improved.

[0067] In the embodiment, the anti-disengagement sheet 4 is used to limit the positions of the outer shell 1 and the middle shell 2, and the number of the anti-disengagement sheet 4 is small, thereby being conducive to improving the assembly efficiency. Moreover, after the anti-disengagement sheet 4 is arranged, the middle shell 2 and the outer shell 1 do not need to be provided with a buckle structure similar to that in the Chinese invention patent with the application publication number CN116505314A to prevent the middle shell 2 from disengaging from the outer shell 1, and the structure of the middle shell 2 and the outer shell 1 can be simpler, the design and processing of the injection mold thereof are facilitated, and the manufacturing cost is reduced.
