Abstract

The invention discloses a data link line as well as a method and a device for controlling the data link line, which belongs to the technical field of electrons. The data link line comprises a first universal serial bus (USB) plug, a second USB plug, a conducting wire group for electrically joining the first USB plug and the second USB plug and a switch part which is arranged on the conducting wire group; the switch part can be switched among a first conduction state, a second conduction state and a third conduction state; a conducting wire for charging in the conducting wire group is conducted when the switch part stays at the first conduction state; when the switch part stays at the second conduction state, a conducting wire for data transmission in the conducting wire group is conducted; when the switch part stays at the third conduction state, the conducting wires for charging and data transmission in the conducting wire group are conducted; and the conducting wire for charging in the conducting wire group is conducted only when the switch part stays at the first conduction state and the third conduction state, so that an effect for charging an intelligent terminal can be realized.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a data connection line, a control method and a device for the data connection line. Background technique [0002] A data connection cable is the most common accessory in smart terminals such as mobile phones, MP3, MP4 or digital cameras. People can connect the smart terminal to the computer through the data connection line, so as to realize the operation of charging and data transmission of the smart terminal. [0003] Please refer to figure 1 , which shows a schematic structural diagram of a common USB (Universal Serial BUS, universal serial bus) data line. The USB data cable includes a first USB plug 110 , a second USB plug 120 and a wire set 130 for connecting the two plugs. The second USB plug 120 can be a Mini USB plug or a Micro USB plug. Wherein, both the first USB plug 110 and the second USB plug 120 include four conductive terminals: a power terminal VCC (Volt Cu...
