[0027] This invention provides a retractable charging data cable with stable conductivity.

[0028] like Figure 1-7 As shown, the stable conductive retractable charging data cable provided in this embodiment of the present invention includes a housing 10, a spring-loaded telescopic structure 20 disposed within the housing 10, a data cable 40 passing through the housing 10 and connected to the spring-loaded telescopic structure 20, and an electrical connection assembly 30 installed within the housing 10 and connected to the spring-loaded telescopic structure 20. The electrical connection assembly 30 includes a first connecting plate 31, a second connecting plate 32, and an electrical connector 33 connected between the first connecting plate 31 and the second connecting plate 32. The first connecting plate 31 is mounted on the housing 10, and the second connecting plate 32 is mounted on the spring-loaded telescopic structure 20 and moves with the spring-loaded telescopic structure 20.

[0029] In this embodiment, the data cable 40 can be pulled out during use and fixed to the desired length by the spring-loaded telescopic structure 20. When not in use, it automatically retracts for easy carrying. Simultaneously, the electrical connection component 30 maintains the connection of the electrical connector 33 during the movement of the spring-loaded telescopic structure 20, thereby improving stability.

[0030] Please refer to Figure 2-3The first connecting plate 31 includes a plurality of through holes 311 arranged side by side. The electrical connectors 33 are correspondingly installed at the through holes 311 and exposed on the surface of the first connecting plate 31, connecting to the second connecting plate 32. The second connecting plate 32 has a plurality of coaxially arranged electrical connecting rings 321, and the plurality of electrical connectors 33 are correspondingly abutting against the electrical connecting rings 321. In this embodiment, each electrical connecting ring 321 is in contact with a different electrical connector 33. When the second connecting plate 32 rotates during the rotation of the spring-loaded telescopic structure 20, the electrical connecting rings 321 remain in contact with the electrical connectors 33 to achieve conductivity.

[0031] In this embodiment, the housing 10 includes a bottom cover 11 with a receiving cavity and a top cover 12 that can be fitted onto the bottom cover 11. The spring-loaded telescopic structure 20 and the electrical connection assembly 30 are both disposed within the receiving cavity. The bottom cover 11 has an exposure hole for the data cable 40 to extend out. The top cover 12 and the bottom cover 11 can be fixed together by snap-fit ​​or bolt connection.

[0032] The spring-loaded telescopic structure 20 includes a positioning disk 21 and a rotating disk 22. The positioning disk 21 has a positioning groove 213. The rotating disk 22 has a positioning post 224 on the side facing the positioning disk 21 that can be held in the positioning groove 213. The data cable 40 can be pulled out by pulling it, and the data cable 40 can be fixed at the required length by the cooperation of the positioning post 224 and the positioning groove 213.

[0033] Alternatively, please refer to Figure 4-7 The positioning plate 21 is directly opened on the face cover 12, and the rotating shaft 13 is set at the axis of the bottom cover 11, which can reduce additional parts.

[0034] The positioning disk 21 includes a first guide block 211 and a second guide block 212 arranged around the axis of the positioning disk 21. The positioning groove 213 is disposed at the end of the first guide block 211. The end of the second guide block 212 near the positioning groove 213 has a guide ramp 214 inclined toward the positioning groove 213.

[0035] The rotating disk 22 has a mounting cavity 221, in which a coil spring 23 is provided. The rotating shaft 13 is connected to the coil spring 23. A fixing block 222 is provided in the mounting cavity 221, and the coil spring 23 is partially fitted onto the fixing block 222.

[0036] Coil spring 23 refers to a spring whose helix lies in a plane. A coil spring is a type of spring where material is wound into a planar helix. One end of the spring is fixed, and when a torque is applied to the other end, the material experiences a bending moment, resulting in elastic bending deformation. Consequently, the spring twists within its own plane. The magnitude of its deformation angle is proportional to the torque, exhibiting high torque and multi-angle torsional torque. Therefore, it is used in mechanisms that operate for extended periods, possessing characteristics that prevent fatigue. Its applications are similar to torsion springs, including applications such as measuring tapes, car starter motors, and cable management boxes.

[0037] Specifically, the coil spring 23 can provide sufficient tension so that the coil can automatically wind up the data cable 40, and can provide corresponding elasticity when stretched. When the data cable 40 is finished and needs to be stored, simply pull the data cable 40 gently and then release it, and the coil spring 23 will automatically store the data cable 40 completely. The purpose of the entire design is to make the data cable 40 easy to store and extend, convenient for users and reduce the tangling and messiness of the data cable 40.

[0038] When the rotating disk 22 rotates, the positioning pin 224 moves within the track on the positioning disk 21. During the pulling process, the positioning pin 224 falls into the positioning groove 213 on the positioning disk 21, causing the positioning disk 21 to stop rotating and achieving the positioning purpose. At this time, the length of the data cable 40 is fixed once. When the data cable 40 is pulled to the appropriate position, it can be gently released and will remain stationary. When the data cable 40 is finished using, it can be gently pulled a little more and then released, and the coil spring 23 will automatically retract the data cable 40 completely. This design allows users to easily store and pull out the data cable 40, preventing it from becoming loose or tangled during the pulling process.

[0039] In addition, the rotating disk 22 has a recessed mounting groove 223 on the side facing the positioning disk 21, and the positioning post 224 is disposed in the mounting groove 223. In this embodiment, by opening the mounting groove 223 to install the positioning post 224, the height of the spring-loaded telescopic structure 20 can be effectively reduced, making it more compact and easier to carry.

[0040] In the above embodiment, the first connecting plate 31 is provided with mounting holes 313 that are fitted onto the rotating shaft 13. The first connecting plate 31 does not rotate to maintain stable connection performance.

[0041] The housing 10 is provided with a positioning shaft 14, and the first connecting plate 31 is provided with a plurality of positioning holes 312, which are connected one-to-one with the positioning shaft 14. In this embodiment, the first connecting plate 31 is further fixed by the cooperation of the positioning shaft 14 and the positioning holes 312, thereby improving its stability.

[0042] In the above embodiment, the electrical connector includes a mounting portion 331 and a protrusion 332 connected to each other. One end of the mounting portion 331 is installed in the through hole 311, and the other end of the protrusion 332 opposite to the mounting portion 331 protrudes outward from the through hole 311 toward the outside of the mounting hole 313, so that the protrusion can stably contact the electrical connector 321 to achieve conductivity.

[0043] In the above embodiments, it is understood that this application does not specifically improve the PCB board on the first connecting board 31. Therefore, the PCB board and other related electrical components can directly adopt the relevant solutions in the prior art, which will not be described in detail here.

[0044] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the concept of the present utility model and using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present utility model.
