▎ 摘　　要

NOVELTY - The assembly has a jack (1) whose end is formed with a blind hole (3). A contact spring ring (2) is installed in the blind hole. The contact spring ring is provided with multiple elastic spring claws (4). A plating layer of the contact spring ring is formed with a gold-graphene composite plating layer. The plating layer of the jack is formed with a gold plating layer or a gold-graphene composite plating layer. The contact spring ring is provided with a spring claw. The spring claw is provided with a spring claw main body. The spring claw main body is provided with a spring (7). USE - Insertion hole assembly for electric connector (claimed). ADVANTAGE - The assembly optimizes spring claw structure, and improves mechanical shelf life of the inserting hole assembly so as to improve mechanical service life of an electric connector. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for plating method of gold-graphene composite plating layer. DESCRIPTION OF DRAWING(S) - The drawing shows a structural schematic representation of the composite plating layer integrated insertion hole assembly for electric connector.
