Description

Charging wire, power adapter, charging system and electronic equipment Technical Field The application relates to the technical field of electronic circuits, in particular to a charging wire, a power adapter, a charging system and electronic equipment. Background In the current field of charging of electronic devices, USB charging wires are widely used for charging operations of various devices. Conventional USB charging lines are typically equipped with only 4 interfaces (or PIN PINs), the main function of which is to fulfill the basic charging requirements. However, there are certain limitations to this design. Whether most power adapters support the fast charge function is often unclear. When the charging cord only supports the normal charging function and the user erroneously uses the power adapter supporting the quick charge, the device will not normally enable the quick charge mode. Disclosure of utility model In order to solve the technical problems, the application provides a charging wire, a power adapter, a charging system and electronic equipment, which avoid the problem that the equipment cannot normally start a quick charging mode when a user uses the power adapter supporting quick charging by mistake when the charging wire only supports a common charging function. The application provides a charging wire, which comprises a first charging branch, a second charging branch, an inverter and a control circuit, wherein the input end of the first charging branch is respectively connected with a voltage bus interface and an enabling interface of the charging wire, the output end of the first charging branch is connected with an output interface of the charging wire, the input end of the second charging branch is respectively connected with the voltage bus interface and the enabling interface, the output end of the second charging branch is connected with the output interface, the first charging branch and the second charging branch are conducted at a high level or a low level, when the first charging branch is conducted, the first charging branch is used for quick charging, and when the second charging branch is conducted, the second charging branch is used for non-quick charging, the inverter is arranged between the input end of the first charging branch and the enabling interface, or between the input end of the second charging branch and the enabling interface, and is used for controlling the conduction and the cut-off of the first charging branch or the second charging branch. The above charging line is used for fast charging and non-fast charging respectively by integrating two charging branches (a first charging branch and a second charging branch) in one charging line. The input end of the second charging branch is also connected with the voltage bus interface and the enabling interface, and the output end is also connected with the output interface. The two branches are conducted at high level or low level, the first charging branch is used for fast charging when conducted, and the second charging branch is used for non-fast charging when conducted. In addition, through setting up the reverser between the input of first branch road or second branch road that charges and enabling the interface, can control the switching of switching on and off of two branches in a flexible way to realize the switching of quick charge and non-quick charge. The problem that the device cannot normally start the quick charging mode when the charging wire only supports the common charging function and a user uses the power adapter supporting the quick charging by mistake is avoided, and meanwhile, the problem that the charging device cannot play a protective role when the charging device is in load short circuit due to the fact that the common power adapter is used due to the fact that the charging wire supports the quick charging is also avoided, so that the charging heat loss is generated is avoided. In one implementation, when the inverter is arranged between the input end of the second charging branch and the enabling interface and the first charging branch and the second charging branch are both in low level conduction, if the enabling interface inputs low level, the first charging branch is conducted and the second charging branch is turned off, and when the inverter is arranged between the input end of the second charging branch and the enabling interface and the first charging branch and the second charging branch are both in low level conduction, if the enabling interface inputs high level, the first charging branch is turned off and the second charging branch is conducted. In one implementation, when the inverter is arranged between the input end of the first charging branch and the enabling interface and the first charging branch and the second charging branch are both in low level conduction, if the enabling interface inputs low level, the first charging branch is turned off and the second charging branc
