[0039] Before any embodiments of the invention are explained in detail, it is to be understood that the invention is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the foregoing drawings.

[0040] In this utility model, the terms "comprises," "includes," "has," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes the element.

[0041] In this utility model, the terms "connect," "couple," and "install" may refer to direct connection, coupling, or installation, or indirect connection, coupling, or installation. For example, direct connection refers to the connection of two parts or components without the use of an intermediary, while indirect connection refers to the connection of two parts or components to at least one intermediary, with the connection being achieved through the intermediary.

[0042] In the present invention, it will be understood by those skilled in the art that the function performed by an assembly can be performed by one assembly, multiple assemblies, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one assembly, or a combination of multiple parts.

[0043] In the present invention, the terms "upper", "lower", "left", "right", "front", "back" and other directional words are described based on the orientation and positional relationship shown in the accompanying drawings, and should not be understood as limiting the embodiments of the present invention. In addition, in the context, it is also necessary to understand that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to the other element "upper" or "lower", but also be indirectly connected to the other element "upper" or "lower" through an intermediate element. It should also be understood that directional words such as upper side, lower side, left side, right side, front side, back side, etc. not only represent the positive orientation, but can also be understood as the lateral orientation. For example, below can include directly below, lower left, lower right, lower front, and lower back, etc.

[0044] When space limitations prevent Ethernet cables from maintaining the recommended minimum bend radius during installation or maintenance, overbending can occur. Overbending can reduce the parallelism of the cable's flexible inner conductors, increasing electromagnetic interference and crosstalk, degrading signal quality, and even damaging the cable.

[0045] In order to solve the above problems, Figure 1-Figure 5 As shown, the present invention provides a cable connector adapter device. The cable connector adapter device includes an inner conductor group, a docking housing 2 and a parallelism retaining frame 5.

[0046] The inner conductor assembly comprises a plurality of parallel, spaced-apart flexible inner conductors 1. These flexible inner conductors 1 are flexible and can be bent at any angle. Each end of the inner conductor assembly is connected to a corresponding docking housing 2, which is used to dock with the patch harness 100 to achieve electrical connection between the patch harness 100 and the flexible inner conductors 1. Parallelism retainers 5 are positioned between the parallel, spaced-apart flexible inner conductors 1 and maintain the parallelism of the flexible inner conductors 1.

[0047] If the flexible inner conductors 1 within an Ethernet cable are not parallel, the distance between them will vary, causing signal interference. Maintaining parallelism ensures that the magnetic fields between the flexible inner conductors 1 cancel each other's interference, reducing crosstalk. Maintaining parallelism helps maintain overall cable impedance stability, minimizing the negative impact of uneven impedance on signal transmission quality. Maintaining good parallelism between the flexible inner conductors 1 reduces signal loss during transmission, especially for high-frequency signals, and enables higher data rates.

[0048] When manufacturing cable connector adapters, it is necessary to follow international standards for cable manufacturing to ensure compatibility and performance.

[0049] Through the above arrangement, the flexibility of the flexible inner conductor 1 can be bent according to actual installation requirements, thereby adapting to installation needs in confined spaces and reducing space usage. The flexible inner conductor 1 is arranged on the parallelism retaining frame 5. During the bending process of the flexible inner conductor 1, the parallelism retaining frame 5 can ensure the parallelism between the flexible inner conductors 1, thereby avoiding increased electromagnetic interference and crosstalk, and ensuring the quality of the transmitted signal. At the same time, because the flexible inner conductor 1 can be bent at any angle, it can prevent damage to the cable during installation in a confined space.

[0050] like Figure 5 As shown, in some embodiments, the parallelism retainer 5 includes retainer shells 51 arranged in parallel and spaced apart. The retainer shells 51 are covered on the flexible inner conductor 1 in a one-to-one correspondence, and the retainer shells 51 are connected by connectors 52. In this embodiment, the retainer shells 51 are made of flexible material to facilitate bending. The retainer shells 51 are hollow structures, and the flexible inner conductor 1 is passed through the retainer shells 51 to facilitate assembly. The retainer shells 51 are connected by connectors 52, which can achieve mutual connection between the retainer shells 51. During the bending process, the retainer shells bend synchronously, facilitating operation. In addition, the connectors 52 can ensure the stability of the parallelism retainer 5 structure.

[0051] In some embodiments, multiple connectors 52 are spaced apart along the extension direction of the cage housing 51. By spacing multiple connectors 52 between the cage housings 51, the parallelism of the cage housings 51 can be further ensured, improving the structural stability of the parallel cage 5. In this embodiment, the connectors 52 have a trapezoidal cross-section. In other embodiments, they can be cylindrical, prismatic, or other shapes, without further limitation.

[0052] like Figure 3 and Figure 4As shown, in some embodiments, the flexible inner conductor 1 includes an adapter portion 11, and a docking pin portion 12 is connected to each end of the adapter portion 11. The retainer shell 51 of the parallelism retainer 5 is coated on the adapter portion 11, and the docking pin portion 12 is fixedly arranged in the docking shell 2. Among them, the adapter portion 11 has a certain flexibility and can be bent according to the needs of the installation position, so as to facilitate reasonable layout in a complex environment. Since the docking pin portion 12 needs to be docked with the connector harness 100, the docking pin portion 12 has a certain hardness and stability, which can ensure that it will not bend or be damaged when plugged into the female terminal in the connector harness 100. The parallelism retainer 5 is coated on the adapter portion 11, which can ensure the parallelism between the flexible inner conductors 1, and will not reduce the network performance after bending.

[0053] like Figure 3 and Figure 4 As shown, in some embodiments, a connecting portion 13 is provided between the docking pin portion 12 and the adapter portion 11. A rigid connector 4 is fixedly mounted on the connecting portion 13, and the rigid connector 4 is connected to the docking shell 2 and the insulating shielding sheath 3. Specifically, in this embodiment, the docking pin portion 12, the adapter portion 11, and the connecting portion 13 form an integrated structure. The flexible inner conductor 1 includes both the docking pin portion 12 with good rigidity and stability and the flexible adapter portion 11 that can be bent at any angle. The three parts are made of the same metal material and are subjected to different heat treatments and processing methods. The metal material can be copper, silver, or gold. After the metal material is heat treated, the docking pin portion 12 and the connecting portion 13 need to be quenched to increase the hardness of the docking pin portion 12 and the connecting portion 13. After the above treatment, the docking pin portion 12 and the connecting portion 13 have higher hardness, and the adapter portion 11 has higher flexibility. Furthermore, by providing a connecting portion 13 to transition between the docking pin portion 12 and the adapter portion 11, and using different quenching processes for the docking pin portion 12 and the connecting portion 13, the flexibility of the material of the flexible inner conductor 1 is gradually transitioned, thus avoiding stress concentration and facilitating the manufacture of the flexible inner conductor 1. By installing a rigid connector 4 on the connecting portions 13, the parallelism between the connecting portions 13 of the flexible inner conductor 1 can be ensured.

[0054] like Figure 4As shown, in some embodiments, the surface of the connecting portion 13 has a protrusion. Specifically, the protrusion can be designed to be barbed, rectangular, cylindrical, etc. Later, the connecting portion 13 and the rigid connector 4 are integrally formed through an injection molding process. By providing the protrusion, it is possible to ensure that the connecting portion 13 is stably connected to the rigid connector 4. The protrusion can increase the contact area with the rigid connector 4 and is not easily damaged. Moreover, since the rigid connector 4 can rigidly limit the connecting portion 13, the parallelism between the connecting portions 13 can be ensured. In other embodiments, parallel and spaced mounting holes can be provided on the rigid connector 13, and a card slot can be provided on the hole wall of the mounting hole. When the connecting portion 13 penetrates the rigid connector 4 through the mounting hole, it is stably engaged with the card slot of the rigid connector 4 to form a tight fit, which can also ensure that the connecting portion 13 is stably connected to the rigid connector 4. In some embodiments, the rigid connector 4 is provided with a shielding structure, which is used to shield the connecting portion 13. By connecting the rigid connector 4 to the insulating shielding jacket 3 , the connection between the connecting portion 13 and the transition portion 11 can be shielded and protected, thereby ensuring signal integrity and shielding effectiveness.

[0055] In some embodiments, the shielding structure includes multiple layers of spaced-apart metal mesh, and the multiple layers of metal mesh are arranged in the rigid connector 4. Specifically, the rigid connector 4 is a composite layered structure of metal mesh and non-metallic material. By arranging multiple layers of metal mesh, the shielding performance of the rigid connector 4 can be guaranteed. When the rigid connector 4 and the connecting portion 13 are injection molded, multiple layers of metal mesh are added to the mold cavity according to the injection molding process, and the multiple layers of metal mesh are staggered to form a complete shielding structure. In other embodiments, a whole metal sheet can also be used to cover the rigid connector 4 or fixedly embedded in the rigid connector 4, which can also ensure a good shielding effect.

[0056] like Figure 2 and Figure 3 As shown, in some embodiments, the cable connector adapter further includes an insulating shielding sheath 3, which is sleeved on the parallelism retaining frame 5, and the insulating shielding sheath 3 is flexible. The insulating shielding sheath 3 can be made of a metal sheet with a shielding function and a certain degree of flexibility. The insulating shielding sheath 3 has a through hole running through it, and the parallelism retaining frame 5 is passed through the through hole. The insulating shielding sheath 3 completely covers the parallelism retaining frame 5, so that the insulating shielding sheath 3 can effectively cover the transition portion 11 of the flexible inner conductor 1. By providing the insulating shielding sheath 3, the signal transmitted by the flexible inner conductor 1 can be shielded to avoid external signal interference, thereby ensuring the quality of the transmitted signal. In other embodiments, the insulating shielding sheath 3 can also be woven from multiple layers of metal mesh, and the multiple layers of metal mesh are staggered to further ensure the flexibility of the insulating shielding sheath 3, and no excessive restrictions are made here.

[0057] like Figure 2 As shown, in some embodiments, one end of the docking housing 2 that docks with the patch harness 100 has a docking socket 21. By providing the docking socket 21, it is convenient to cooperate with the patch harness 100 for plugging.

[0058] like Figure 6-Figure 7 As shown, this embodiment also provides a cable connector adapter device, including a flexible inner conductor 1 and an adapter housing 200. The flexible inner conductors 1, which are arranged in parallel and spaced apart, are fixedly embedded in the adapter housing 200. The adapter housing 200 is used to dock with the patch harness 100 to achieve electrical connection between the patch harness 100 and the flexible inner conductor 1. For extreme 0° bending conditions, the flexible inner conductor 1 is directly embedded in the adapter housing 200, and the adapter housing 200 is used to make the embedded flexible inner conductors 1 parallel to each other. The adapter portion 11 of the flexible inner conductor 1 can be covered with an insulating shielding sheath 3, or a shielding structure can be directly provided on the adapter housing 200 corresponding to the adapter portion 11. No excessive restrictions are imposed here.

[0059] This embodiment also provides an Ethernet system, including a patch harness 100 and the cable connector adapter as described above. The patch harness 100 is docked with the cable connector adapter to ensure the signal quality of cable transmission and avoid cable damage.

[0060] This embodiment also provides a vehicle, including a vehicle body and the above Ethernet system. The Ethernet system is arranged in the vehicle body, which can ensure the signal quality of cable transmission and avoid cable damage.

[0061] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation methods here.
