Description

Technical Field

[0001] This utility model relates to a first plug connector and a connector assembly, belonging to the field of connector technology. Background Technology

[0002] Connector assemblies in related technologies typically include a receptacle connector and a plug connector that mates with the receptacle connector. The receptacle connector has a receiving slot, and the plug connector has a tongue that matches the shape of the receiving slot and is configured to be inserted into the receiving slot.

[0003] However, with the diversification of market requirements for connector transmission, various connector assemblies with similar appearances exist in related technologies. This leads to confusion among users, who may insert a plug connector into an incompatible socket connector, thereby damaging the plug connector and / or the socket connector.

[0004] In practice, because plug connectors with wider tongues cannot be inserted into mismatched socket connectors with narrower receiving slots, users can easily identify the insertion error in such cases without causing any substantial damage to the plug connector or the socket connector.

[0005] However, when a plug connector with a narrow tongue is inserted into a mismatched socket connector with a wide receiving slot, the lack of a corresponding protective structure often makes it very easy for the plug connector and / or the socket connector to be damaged. Utility Model Content
