The invention relates to a push-pull type round electric connector, mainly comprising filtering sockets, a head component and a tail accessory, wherein one end of each filtering socket is connected with one end of the head component; the other end of the head component is connected with the tail accessory; the other end of each filtering socket is connected with a commutator; the commutator is provided with multiple transformation jacks; the multiple transformation jacks are inserted into the filtering sockets correspondingly; and the commutator is arranged on a mounting panel of the filtering socket. The commutators are directly arranged on a mounting panel of equipment and the filtering sockets are inserted into the commutators so as to realize quick installation of the sockets. The connector is compact in structure and reasonable in design; the filtering sockets are convenient to assemble and good in sealing performance; plugs are firmly connected with the sockets, quick to insert and pull out and convenient to maintain; and the connector adapts to the miniaturization development trend of existing equipment.
