ABSTRACT:
A digital signal-input/output socket structure comprises a guide post, a housing and two insulation sleeves. One end of the guide post connects a signal line, the other end allows insertion of a core post of an RCA plug of 75 Ω (ohm). A grounding piece is extended over the outer periphery the housing; the grounding piece is connected with the housing using a fixing nut. Two ends of the two coaxial insulation sleeves contacting with each other cooperatively form an annular groove; the guide post has peripherally thereof a protruding annular flange for engaging with and being positioned in the annular groove. The structure suits electric connection of digital and video signal lines etc. of an audio and video unit; it can make the characteristic impedances of the signal lines on the two ends of the socket and the plug match with each other after connecting of the socket with the plug, thereby signals can be accurately transmitted.
