3) the clamping force of the U-shaped dentate conductor is utilized to ensure the full meshing of the inserted sheet conductor of the electric connector;

4) the positioning and the limiting of the electric connector conductor after the contact with the U-shaped conductor are realized by utilizing the dentate structure and the clamping force of the U-shaped conductor;

5) the two cavities and the four U-shaped conductor openings provide reliable support for the electric connector 800 after being inserted, and meanwhile, the electric connector 800 is firmly fixed on the corresponding position of the power distribution device after being inserted by utilizing the meshing force of the U-shaped dentate conductors and the clamping force of the four U-shaped conductor openings, so that the natural separation and falling of the electric connector 800 under different space and direction states of the power distribution device are avoided.

When the electrical connector conductor is inserted into the corresponding U-shaped conductor of the power distribution unit, the electrical connector extension 802 is inserted into the securing slot 900 of the second housing 102.
