[Technical Field]

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS This application claims the benefit of Chinese Patent Application No. CN202011296571.6, filed with the State Intellectual Property Office of China on November 18, 2020, the entire disclosure of which is incorporated herein by reference.

[0002] The present invention relates to an adapter, a plug connector assembly including the adapter, and a connector assembly including the plug connector assembly. [Background technology]

[0003] In the prior art, both RJ45 plug connectors and RJ45 socket connectors are standard connector products. Generally, the housing of an RJ45 plug connector includes a resilient locking structure and an unlocking press for pressing the resilient locking structure. When the RJ45 plug connector and the RJ45 socket connector are coupled to each other, the resilient locking structure of the RJ45 plug connector is in a locked position, in which the resilient locking structure engages with the RJ45 socket connector, thus locking the RJ45 plug connector and the RJ45 socket connector to each other. Therefore, when the RJ45 plug connector needs to be removed from the RJ45 socket connector, the resilient locking structure must be pressed to an unlocked position, in which the resilient locking structure is separated from the RJ45 socket connector by the unlocking press, and then the RJ45 plug connector can be removed.

[0004] In the prior art, the elastic locking structure needs to be pressed to the unlock position and separated from the RJ45 socket connector by the unlock pressing portion, so it is not possible to achieve a quick insertion operation between the RJ45 plug connector and the RJ45 socket connector.
