Description

Technical Field

[0001] The utility model relates to the technical field of charging devices, in particular to a retractable data line device. Background Art

[0002] Since traditional data cables are generally long and inconvenient to carry, if they are placed directly on a table or in a bag, they are easily entangled with themselves and other items, causing inconvenience in use. For this reason, people have invented various single-pull and double-pull retractable data cables, the basic structure of which is to set a rotatable wheel core assembly in the shell, and the data cable is wound on the wheel core assembly to achieve winding. For example, the single-pull retractable data cable, its wire material includes a fixed end and a movable end, the fixed end cannot be stretched, and the movable end can be stretched. In order to achieve the transmission of current and signals between the fixed end and the movable end, it is generally necessary to set a switching mechanism to achieve electrical switching. The traditional approach is to set two plates, one moving and one static, which can rotate relative to each other, such as the moving plate is a circuit board, and a conductive ring is set on it. The static plate is provided with an electrical connector, and the electrical connector has an arc-shaped conductive spring sheet, the conductive spring sheet is in contact with the conductive ring, and the fixed end is connected to the electrical connector, so that the movable end can be electrically connected to the fixed end when the circuit board rotates (the main difference between double pull and single pull is that both plates are rotatable and both are movable ends). However, since the electrical connector needs to be assembled after the static board is formed, and the electrical connector itself is small in size, the assembly operation is relatively complicated, the assembly efficiency is low, and the technical requirements of the workers are high. In addition, since the electrical connector is always under the pressure of the dynamic board, the stability is poor, and the probability of failure after long-term use is high. If the electrical connector fails, the entire data cable device will be scrapped, thereby affecting the service life and increasing the cost. Utility Model Content
