The present disclosure provides a quick connect and disconnect cable junction box, including: a box body, insulators, copper busbars, connection wires, T-shaped cable terminals, linear adapters, and an insulation spacer. The insulators, the copper busbars, the connection wires, and the T-shaped cable terminals are positioned inside the box body. The linear adapter includes a conductive rod, an insulation layer, a quick engagement connector, and a housing. One end of each of three linear adapters is electrically connected to the T-shaped cable terminal inside the box body. The three linear adapters, three T-shaped cable terminals, three connection wires, and three copper busbars form a three-phase electrical path. During operation, the three copper busbars are correspondingly connected to three phase lines of an incoming cable of a ring main unit; and the three linear adapters are engaged with quick connectors of three bypass cable connectors via the quick engagement connectors thereof.
