An electrical connection device (200) connected between a main body and a draw-out device of an electrical appliance having a draw-out structure. The electrical connection device comprises: a draw-out device connection assembly (202) being fixed on the draw-out device and electrically connected to inlet and outlet ends of the draw-out device; a main body connection assembly (204) including contact pieces (241, 441, 541) with a clamping mechanism, wherein the clamping mechanism makes the contact pieces (241, 441, 541) close to and clamp main body busbars (208, 408, 508); and a flexible assembly (206) connecting the draw-out device connection assembly (202) and the main body connection assembly (204) to form a conductive path. The contact pieces (241, 441, 541) of the main body connection assembly (204) are offset by adapting to the position deviation of the main body busbars (208, 408, 508), so that the contact pieces (241, 441, 541) close to and clamp the main body busbars (208, 408, 508), and the flexible assembly (206) absorbs the offset of the contact pieces (241, 441, 541) by its own deformation, the offset is not transferred to the draw-out device connection assembly (202). It is further disclosed a linked electrical connection assembly formed by the described electrical connection devices (200) as well as an electrical appliance using the described electrical connection devices (200) or the electrical connection assembly.
