Auto termination type capacitive coupled connector

Claim 1

An auto termination type capacitive coupled connector comprising a metal connector body and a filter circuit, said metal connector body having a radial flange around the periphery thereof, a BNC jack at one end for connecting a BNC plug, and an externally threaded coupling portion between said radial flange and said BNC jack for connection to a conductive panel by an internally toothed cushion ring and a nut, wherein said filter circuit comprises: an annular groove made around the outside wall of said metal connector body and disposed between said radial flange and said externally threaded coupling portion; an annular insulator mounted around said externally threaded coupling portion and covering said annular groove, said annular insulator comprising a plurality of equiangularly spaced radial through holes, a radial projecting wall at an outer side, an outer annular flange raised from said radial projecting wall and covering part of said externally threaded coupling portion; a plurality of capacitor elements respectively received in one of said radial through holes on said annular insulator, each capacitor element having one end disposed in contact with said annular groove of said metal connector body; and a metal ground ring fastened to said annular insulator to hold down said capacitor elements, said metal ground ring comprising a plurality of projecting strips spaced around the border thereof and respectively inserted into a said hole on said annular insulator to hold down a respective said capacitor element permitting the capacitor element to be connected between said metal ground ring and said annular groove of said metal connector body, and a plurality of unitary hooks respectively spaced between adjacent said projecting strips and hooked on the border of said radial projecting wall.
