The invention discloses a novel distribution box for a smart home. The novel distribution box comprises a top cover and a distribution box device. The distribution box device comprises a casing, a circuit control device, a main transmission mechanism, a first auxiliary transmission mechanism, a second auxiliary transmission mechanism, a conduction mechanism, a wiring device, and an operating device. An arc rack rotates leftward to drive a rack to move leftward, a limit block acts as a limit, and the rack moves leftward to allow an insulating plate to move leftward so as to drive a conduction block to be clamped into a frame-shaped interior formed by a first circuit-on block and a second circuit-on block, so that a first circuit conducting wire and a second circuit conducting wire are connected to each other. An operation panel can operate a wiring port, and if a power supply needs to be powered off, the conduction block is moved rightward by pressing a reverse switch on a forward and reverse switch, so that the first circuit conducting wire and the second circuit conducting wire are disconnected.
