Abstract: Disclosed in the present invention is an electric switching apparatus, comprising a drawer apparatus, an electric connection apparatus, a driving mechanism, and a locking mechanism. A busbar of the breaker body at the separate position is separated from the electric connection apparatus, and the breaker body cannot be switched on. The busbar of the breaker body at the trial position is separated from the electric connection apparatus, and the breaker body can be switched on. The busbar of the breaker body at the connected but not clamped position is in touch with the electric connection apparatus, the electric connection apparatus does not clamp the busbar, and the breaker body cannot be switched on. The busbar of the breaker body at the connected and clamped position is in touch with the electric connection apparatus, the electric connection apparatus clamps the busbar, and the breaker body can be switched on.

Abstract: An electrical connection device is connected between a main body and a draw-out device of an electrical appliance having a draw-out structure. The electrical connection device includes: a draw-out device connection assembly 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 including contact pieces with a clamping mechanism, wherein the clamping mechanism makes the contact pieces close to and clamp main body busbars; and a flexible assembly connecting the draw-out device connection assembly and the main body connection assembly to form a conductive path. The contact pieces of the main body connection assembly are offset by adapting to the position deviation of the main body busbars. A linked electrical connection assembly is formed by the described electrical connection devices and an electrical appliance using the described electrical connection devices or the electrical connection assembly.

Abstract: 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.
