It can be easily stored after use, greatly improving the flexibility of use and the convenience of carrying.

[0018] 3. The setting of the first mounting column in the embodiment of the utility model provides a stable mounting interface for the conductive slider assembly, ensuring the stability and reliability of the conductive path; since the conductive slider assembly is usually matched with the conductive slip ring assembly through an elastic conductive member, the conductive slider assembly itself will be held and fixed on the inner wall of the second shell under the reaction force of the elastic conductive member. Therefore, when the conductive slider assembly is installed on the second shell, it is only necessary to set the first mounting column to position and fix the conductive slider assembly, and there is no need to use a complicated process or fixing method to completely fix the conductive slider assembly, which effectively reduces the difficulty of assembly and is conducive to improving production efficiency.

[0020] 5. The design of the first locking boss and the locking notch in the embodiment of the utility model, as well as the cooperation of the protrusion on the swing bracket, form a reliable locking mechanism, which not only enhances the fixation of the cable at a specific length, but also ensures its stability and does not fall off during use, thereby improving the safety of use and ease of operation of the telescopic cable module.

[0023] 8. The avoidance groove at the bottom of the third installation groove of the embodiment of the utility model provides necessary space for the rotating gear, avoids interference with other components, ensures the smooth operation of the rotating gear, reduces mechanical wear, and improves the service life and working efficiency of the telescopic line module.

[0024] 9. The cable winding assembly of the embodiment of the utility model includes a cable winding body and a data cable structural design. One end of the data cable is electrically connected to the sliding conductive assembly, and the other end is exposed through the shell assembly, thereby realizing flexible extension and retraction and efficient transmission of the data cable, ensuring stability and practicality in various usage conditions, and improving the user experience during charging and data transmission.

The first to third mounting positions carefully arranged on the second housing provide precise mounting positions for the sliding conductive assembly and the positioning assembly, optimize the internal space utilization rate, and help to achieve the miniaturization design of the module; and the second mounting position and the third mounting position are arranged around the first mounting position, and the key components are distributed around the first mounting position as the center point, so that the force can be evenly distributed, so that the housing assembly is more stable when subjected to stress, and the structural deformation or damage caused by excessive local force is prevented, thereby enhancing the overall structural strength and stability of the telescopic cable module.

[0080] 3. The setting of the first mounting column in the embodiment of the utility model provides a stable mounting interface for the conductive slider assembly, ensuring the stability and reliability of the conductive path; since the conductive slider assembly is usually matched with the conductive slip ring assembly through an elastic conductive member, the conductive slider assembly itself will be held and fixed on the inner wall of the second shell under the reaction force of the elastic conductive member. Therefore, when the conductive slider assembly is installed on the second shell, it is only necessary to set the first mounting column to position and fix the conductive slider assembly, and there is no need to use a complicated process or fixing method to completely fix the conductive slider assembly, which effectively reduces the difficulty of assembly and is conducive to improving production efficiency.

[0081] 4. The swing bracket and rotating gear design of the positioning assembly of the embodiment of the utility model realizes precise control of the telescopic position of the winding assembly through precise mechanical coordination, avoiding excessive stretching or retraction, which not only protects the data cable, but also facilitates the user to quickly adjust the cable length in different usage scenarios, thereby improving the flexibility and comfort of use.

[0082] 5. The design of the first locking boss and the locking notch in the embodiment of the utility model, as well as the cooperation of the protrusion on the swing bracket, form a reliable locking mechanism, which not only enhances the fixation of the cable at a specific length, but also ensures its stability and does not fall off during use, thereby improving the safety of use and ease of operation of the telescopic cable module.

[0083] 6. The electrical interface on the sliding conductive component of the embodiment of the utility model is exposed through the avoidance hole on the shell component, so that the data cable can be easily connected to the external device, which simplifies the user's operation steps and improves the convenience and practicality of the connection. At the same time, the design of the avoidance hole avoids the interface from being damaged by the outside when not in use, thereby enhancing durability; when the telescopic line module is installed on other equipment, electrical connection can be achieved through the electrical interface.

[0084] 7. The design of the second mounting groove in the second mounting position and the third mounting groove in the third mounting position of the embodiment of the utility model provides a precise positioning and mounting area for the conductive slider assembly and the rotating gear, making the fit between the components tighter, which helps to improve the stability of the overall structure. At the same time, the internal space is further optimized by avoiding the grooves, which promotes the lightweight design of the product.

[0085] 8. The avoidance groove at the bottom of the third installation groove of the embodiment of the utility model provides necessary space for the rotating gear, avoids interference with other components, ensures the smooth operation of the rotating gear, reduces mechanical wear, and improves the service life and working efficiency of the telescopic line module.

[0086] 9. The cable winding assembly of the embodiment of the utility model includes a cable winding body and a data cable structural design. One end of the data cable is electrically connected to the sliding conductive assembly, and the other end is exposed through the shell assembly, thereby realizing flexible extension and retraction and efficient transmission of the data cable, ensuring stability and practicality in various usage conditions, and improving the user experience during charging and data transmission.

[0087] 10. The embodiment of the utility model further provides an electrical connection device, which is equipped with the above-mentioned telescopic wire module, and thus has the same beneficial effects as the above-mentioned telescopic wire module, which will not be elaborated here.

[0088] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
