The invention discloses a power supply branch plug. The power supply branch plug is connected to a power supply, comprises a primary output joint and an auxiliary output joint, which are connected to a plurality of electric equipment for supplying power, and further comprises a controller, wherein the controller is used for controlling the switch-on or turn-off of a loop of the auxiliary output joint according to a current and / or a voltage value of a loop of the primary output joint. The power supply branch plug provided by the invention can optimize wiring of a power supply circuit, reduces the occupied space of the power supply circuit, and realizes the linkage of switch-on or turn-off of the plurality of electric equipment at the same time.
Description
technical field [0001] The invention relates to a power adapter, in particular to a power adapter with a power branch plug. Background technique [0002] In the prior art, when supplying power to multiple electrical devices, it is necessary to provide the same power supply as the number of electrical devices, so that multiple electrical devices are connected to the power grid, which will cause the problem of complicated power lines. There are also some electrical equipment, which itself has a power socket socket, through which these electrical equipment can realize power linkage with other electrical equipment. The above-mentioned power supply methods have the problem of complicated wiring, need to consume a relatively large amount of wire materials and occupy a relatively large space for power consumption, even those electrical equipment that have their own power supply linkage socket sockets, there are some limitations, such as the need for special Designing sockets and s...
