Patent ID: 7476127

Claim:
An adapter for mini-coaxial cable used to mechanically and electrically connect a mini-coaxial cable to a standard coaxial cable connector, the mini-coaxial cable including an outer sheath, a braided sheath, an insulating spacer, and a center conductor; a front end of the mini-coaxial cable being stripped by a predetermined length to bare the center conductor and expose the insulating spacer and the braided sheath thereat before connecting to the adapter and the standard coaxial cable connector; the adapter comprising: a cylindrical member having a tubular portion internally defining a first receiving bore and a second receiving bore located before and communicable with the first receiving bore; the first receiving bore having an inner diameter large enough for receiving the bare center conductor and the exposed insulating spacer of the mini-coaxial cable therein; and an electrically conductive insertion member having a rear part and a front part coaxially extending therefrom, the rear part including tubular annular portion tightly fitted in the second receiving bore of the cylindrical member, and the front part including plurality of segments forward extended outside the second receiving bore for receiving the bare center conductor therebetween, the segments being biased apart one from the other; whereby when the adapter is moved into the standard coaxial cable connector, the segments of the adapter are radially compressed by the standard coaxial cable connector to thereby tightly grip the bare center conductor received therein and ensure electrical connection of the mini-coaxial cable to the standard coaxial cable connector.
