This invention relates to a circumferentially
mating plug and socket, comprising a plug body and a socket body. The plug body includes a first insulating base, and its top is coaxially arranged with a first protective ring, a
first insertion ring, a second insulating ring, a second
insertion ring, a third insulating ring, a third
insertion ring, a fourth insulating ring, and a fourth
insertion element, all of which are conductive to the plug wires. The socket body includes a second insulating base, and its top is coaxially arranged with a second protective ring, a
first insertion ring, a fifth insulating ring, a second insertion ring, a sixth insulating ring, a third insertion ring, a seventh insulating ring, and a fourth insertion ring, all of which are conductive to the socket wires. During
mating, each insulating ring of the plug inserts into its corresponding positioning ring, and the insertion ring inserts into its corresponding insertion ring, achieving precise circumferential
mating and conductive connection. This circumferentially
mating plug and socket, by employing a concentric circle structure, enables mating of the plug and socket in any direction, greatly reducing the difficulty of plug-socket connection and facilitating automated mating of the plug and socket.
