The invention relates to the field of sockets, in particular to an elastic side-moving blocking socket. The socket includes a top shell, an alignment slot, an alignment jack, an insertion bottom shell and terminals, the bottom of the top shell is fixed with an insertion bottom shell, and the top surface of the top shell is provided with a The alignment slot, and the bottom of the alignment slot is symmetrically provided with alignment jacks, the bottom of the plug-in bottom shell is symmetrically fixed with terminals, the top shell is equipped with a main board inside, and the surface of the main board is located on the alignment jack The corresponding position is electrically installed with a plug-in component, and a blocking mechanism is installed inside the top shell between the plug-in component and the alignment jack, and an insulating block is fixed inside the plug-in bottom case between the main board and the terminal. The invention installs a fuse in the passage for conduction, and when overload occurs, it breaks and the insulating base frame moves sideways to realize the insulation blocking of the passage, which not only has the effect of overload protection, but also has a better blocking effect of the elastic lateral movement.
