As a very popular scalable data line in our daily life, it has been liked by many people. When we purchase data lines, the flexible data line has become the most popular data line we choose during the purchase process.

The Principle of Box shaped Scalable Data Line to Realize Scalability

The expansion data line can be rolled up because there is a spring in the box. When pulling out the measuring length, it lengthens the data line and the spring. Once the data line is used, the spring in the box will automatically shrink, and the data line will also shrink under the effect of the spring force, so the data line will be rolled up.

The retractable data line is that the electronic scientific researchers use the tape principle to develop the original data line into an automatic retractable function, making it convenient for users to carry and small storage space. Let the traditional data line automatically shrink freely, no longer be afraid of knotting, breaking, temporary space, etc. of the traditional data line.

Generally, there are few dedicated data lines. The common phenomenon is that one data line can be used for multiple mobile phone models. Some models of data lines are exaggerated. One line can use 30-40 different types of mobile phones. See the table of Xunfeng Communication for the specific universal models (most universal models have been summarized authoritatively at present).
