Provided are an electric shock prevention and protection device, a power distribution functional module, and a power distribution apparatus. The electric shock prevention and protection device comprises an insulated protective slide member, a slide member connection assembly, and a protective driving assembly. The slide member connection assembly is provided at an adaptor assembly end connector. The insulated protective slide member is slidably connected to the slide member connection assembly. The protective driving assembly is provided at a power distribution assembly end connector of a power distribution assembly for achieving an insertion connection with the adaptor assembly end connector. When the power distribution assembly end connector is located away from the adaptor assembly end connector, the protective driving assembly drives the insulated protective slide member to move along a preset path to reach a position at which the head of the adaptor assembly end connector is shielded. When the power distribution assembly end connector is close to the adaptor assembly end connector, the protective driving assembly drives the insulated protective slide member to move along the preset path to reach a position at which the head of the adaptor assembly end connector is exposed.
