Description

Technical Field

[0001] The utility model relates to the technical field of data line devices, in particular to a telescopic data line device with one input line dragging two independent output lines. Background Art

[0002] Data cables are mainly used for charging or data transmission for electronic devices such as mobile phones and cameras. Since data cables are generally long and inconvenient to carry, if they are placed directly on a table or bag, they are easy to get entangled with themselves and other items, causing inconvenience to users. For this reason, people have invented various retractable data cables, which are wound by setting a spring (spiral shrapnel) in the main part of the data cable to cooperate with the wheel core to reel the data cable, so as to achieve the effects of being more compact and anti-entanglement. At the same time, since there are many different types of interfaces in current mobile phones, mainly TYPE-C interface and Lightning interface. In order to be able to adapt to charging mobile phones with different interface types at the same time, people have designed one-to-two, one-to-three and other data cables. In order to further facilitate use, people have also invented two independent output cables, so that each output cable can be pulled out and used separately. However, the current retractable data cable device designs the two output cables into two sets of completely independent assembly structures, that is, each output cable corresponds to a set of wheel core, spring, moving plate, static plate and guide sliding structure, and the two sets of assembly structures are installed together in the same housing to form a one-to-two independent retractable data cable structure. This structure firstly results in a significantly larger overall thickness of the entire product; secondly, there are more circuit boards, usually five, and more than thirty solder joints, which results in higher costs, greater processing difficulty, and lower yield rates.
