Bistable arc extinguishing mechanism

The utility model discloses a bistable arc extinguishing mechanism. The mechanism comprises an insulation housing made of metal, an optical fiber coupling module, a voice/data standby access module, a power supply module group, a video distribution module, a voice distribution module, a data distribution module, a switch module, a hub module, and a wireless route module; the optical fiber coupling module, the voice/data standby access module, the power supply module group, the video distribution module, the voice distribution module, the data distribution module, the switch module, the hub module and the wireless route module are positioned in the insulation housing; and the modules adopt a cable/wireless transceiving device as a connection means, and adopt optical fiber for main signal access manner. The mechanism has the advantages that firstly, the mechanism conducts transmission through an optical fiber interface, so as to increase the speed and the capacity of data signals, reduce accessed connection wir
