A coaxial cable F-connector (20) includes a tubular post (32) for insertion around the dielectric (26) of the coaxial cable (22), a cylindrical body member (46) secured to the tubular post for receiving the jacket (30) of the coaxial cable, and a coupling nut (38). The tubular post includes an enlarged shoulder (80) that extends inside the nut; the nut includes an inwardly directed collar (82) that extends around the tubular post and around one end of the cylindrical body member. An O-ring (35) is disposed around one end of the cylindrical body member between the shoulder of the tubular post and the collar of the coupling nut. Limited axial movement of the coupling nut is permitted relative to the tubular post and cylindrical body member for allowing the coupling nut to spin free of the O-ring until tightening of the coupling nut over the threaded port is almost complete. Upon final tightening of the coupling nut, the O-ring forms a seal between the nut, the tubular post, and the cylindrical body member.

L'invention porte sur un connecteur F (20) pour câble coaxial comportant une tige tubulaire (32) insérable autour du diélectrique du câble coaxial, un corps cylindrique fixé à la tige tubulaire et recevant la gaine (30) du câble coaxial et un écrou de couplage (38). La tige tubulaire comprend un épaulement élargi (80) s'étendant à l'intérieur de l'écrou. L'écrou comporte un collier (82) dirigé vers l'intérieur entourant la tige tubulaire et l'une des extrémités du corps cylindrique. Un joint torique (35) est placé autour de l'une des extrémités du corps cylindrique entre l'épaulement de la tige tubulaire et le collier de l'écrou de couplage. L'écrou de couplage peut effectuer des mouvements axiaux limités lui permettant de tourner librement sans interférer avec le joint torique jusqu'à ce que son serrage sur l'orifice fileté soit presque complet. Lorsque le serrage est achevé, le joint torique assure une liaison étanche entre l'écrou, la tige tubulaire et le corps cylindrique.
