Radio frequency common ground connector

The invention provides a radio frequency common ground connector which comprises a base module, a plurality of wires electrically connected with the base module and a grounding piece, each wire comprises an inner conductor, an inner insulating layer, a metal shielding layer and an outer insulating layer from inside to outside, and the wiring ends of the wires are connected with the grounding piece. The connecting end of the metal shielding layer extends forwards relative to the outer insulating layer, the connecting end of the inner conductor extends forwards relative to the connecting end of the metal shielding layer, and the connecting end of the metal shielding layer of each wire is electrically connected with the same grounding piece. According to the radio frequency common-ground connector, the connecting end of the metal shielding layer of each wire is connected with the same ground lug, so that the electromagnetic field intensity around each wire is basically the same, the stability of signal transmiss
