The invention relates to the field of signal connectors and particularly relates to a long-distance-unlocking communication-used Ethernet port plug and an Ethernet connector. The long-distance-unlocking communication-used Ethernet port plug uses the front end as a plug-in end and includes a casing. A locking elastic sheet is arranged on the casing. The front end of the locking elastic sheet is fixed on the casing and the rear end extends in a rear upper direction and forms a cantilever structure. A pressure sheet is also arranged on the casing. The rear end of the pressure sheet is fixed on the casing and the front end extends in a front upper direction and overlaps the locking elastic sheet at a place above the locking elastic sheet. Undoubtedly, the pressure sheet increases the distance at which the locking elastic sheet can be operated; and at the same time, because a sheet-type structure is adopted, effects on the dimension of the Ethernet port plug is little. Therefore, the long-distance-unlocking communication-used Ethernet port plug solves a problem that unlocking of the Ethernet port plug and an Ethernet port socket which is assembled comparatively deeply is inconvenient.
