Description

[Technical Field]

[0001] This utility model relates to the technical field of charging cable telescopic winding mechanism, and in particular to a cable telescopic winding mechanism that is easy to assemble and has high operational reliability, with simplified process, reduced cost, long service life, and simpler process. [Background Technology]

[0002] Data cables are common products in people's daily lives. To facilitate the storage of the cables, retractable cable boxes that can automatically retract have appeared on the market. One end of the data cable is usually connected to a data connector, such as a Type-C interface or an Apple connector, while the other end is connected to the circuit board inside the box via electrical contact. External conductive components are then fixed on the outside of the storage box.

[0003] For existing telescopic junction box products, the conductive connecting plate and contact plate generally adopt the conductive structure of spring sheet. In the actual assembly process, the Pin is usually placed separately in the mounting slot first, and then injection molded or pressed to limit and fix it. In actual application, this design structure is prone to wear on the PCB board when the connecting plate rotates axially. Over time, it will affect the electrical connection effect and is not conducive to improving assembly efficiency.

[0004] For example, the utility model patent with application number CN202322261314.4 and patent name "A Double-Track Double-Positioning Single-Pull Data Cable Telescopic Box" specifically discloses a double-track double-positioning single-pull data cable telescopic box, including a bottom shell and a top shell. The bottom shell and the top shell are fastened together to form a closed cavity. The cavity contains a take-up reel, a data cable, a spring, a connecting plate, a contact plate, a contact spring, and a guide pin. A rotating shaft is provided on the bottom shell in the middle of the inner side of the cavity. The take-up reel is rotatably mounted on the rotating shaft. The top of the rotating shaft is screwed to the top shell. The take-up track and the release track are two elliptical tracks that can be switched on each other and are located on the same plane. The elliptical tracks have a major axis and a minor axis. On the inner side of the take-up track and the release track, the transition between the major and minor axes of the release track and the take-up track is provided with a first switching port and a second switching port, as well as a first positioning port and a second positioning port. The beneficial effect of this utility model is that by adding positioning ports, the pull-out length of the data cable is more accurate.

[0005] In the aforementioned prior art, the contact spring is prone to friction damage, which weakens the conductivity and complicates the manufacturing process, making it difficult to improve assembly efficiency. [Utility Model Content]

Over time, this will affect the electrical connection effect and is not conducive to improving assembly efficiency.
