Abstract: A high-current high-frequency electrical connector plug applicable to network data transmission includes a plug housing and a bayonet socket integrated in an inserted manner. The bayonet socket includes an upper terminal block, a lower terminal block and an insulating plastic body. An insertion cavity for placing a socket tongue of an electrical connector receptacle is formed in the insulating plastic body. The upper terminal block and the lower terminal block are inserted and fixed into the insertion cavity respectively. The periphery of the plug housing is sequentially provided with a left rounded part, a right rounded part, a left chamfered part and a right chamfered part. Specific sizes of the left rounded part and the right rounded part need to be controlled.
