RCA sockets typically include a base assembly, typically soldered to a circuit board, and a socket assembly, typically extending through a product housing, which typically includes an outer ground ring surrounding an outer layer, an inner conductive ring surrounding an inner layer, and an insulating layer sandwiched therebetween. In an inner conductive ring structure of an existing RCA socket assembly, a plurality of axial grooves are cut downwards from the top end on the tubular wall of an inner conductive ring, so that a plurality of holding claws are formed at the upper end of the inner conductive ring, and a gap is formed between the outer wall of the inner conductive ring and an insulating layer, so that the holding claws of the inner conductive ring have certain radial contraction elasticity; referring to fig. 1, another inner conductive ring 101 is formed by winding a metal sheet directly into an irregular ring shape so that a part of its inner wall is in contact with the RCA plug; the socket assembly 100 and the base assembly 200 are fixed by extending an annular rivet 1021 on the inner wall of the bottom end of the outer ground ring 102, and riveting the rivet to the base assembly 200. However, the two internal conductive ring structures have weak contraction elasticity, are easy to loosen when being in splicing fit with the RCA plug, and are easy to cause poor conduction with the RCA plug due to metal fatigue after long-term use; this riveting of the socket assembly to the base assembly causes relative rotation between the two during the external threading of the lock, which can result in damage to the RAC socket or a solder failure with the circuit board.
