Coaxial cable connector and method of terminating a cable using same
First Claim
1. A coaxial cable connector having two threadedly engagable parts for terminating an end of a coaxial cable having a sheath and a conductor, said connector comprising in combination:
- (a) a first part comprising a rear nut body for receiving and gripping the sheath of the coaxial cable, said nut body including(1) a ferrule disposed within said rear nut body for at least partially circumscribing the sheath, said ferrule including means for floating said ferrule relative to said rear nut body upon engaging the cable with said rear nut body;
(2) first and second ramp means for radially inwardly compressing opposed ends of said ferrule;
(3) a mandrel for penetrating the cable adjacent the inner surface of the sheath in juxtaposed relationship with said ferrule;
(b) a second part comprising a front nut body for receiving and gripping the conductor of the coaxial cable, said front nut body including(1) an electrode;
(2) means for interconnecting the conductor with said electrode;
(c) means for translating at least one of said first and second ramp means toward the other one upon threaded engagement of said first and second parts to compress said ferrule; and
(d) visually perceivable means for limiting the extent of threaded engagement between said rear nut body and said front nut body.

Abstract
A two part coaxial cable connector includes a rear nut housing a ferrule for gripping the sheath of a coaxial cable and a front nut body for gripping the conductor upon threaded engagement of the rear and front nut bodies. A mandrel, located within and protected by the rear nut body, slides within the sheath upon feeding of the cable into the rear nut body. A pair of annular inclined surfaces or ramps compress the ferrule at opposed edges to squeeze the ferrule into gripping engagement with the sheath. Simultaneously, a collet in the front nut body is compressed to grip the conductor. To facilitate the feeding of a seamed or off round sheath, the ferrule, mandrel and associated parts float within the rear nut body. A positive visually apparent physical interference between the rear and front nut bodies prevents overtighting and resulting damage.

22. A method for terminating a dressed end of a coaxial cable having a sheath and a conductor with a coaxial cable connector having a rear body threadedly engagable with a front nut body, said method comprising the steps of:
-
(a) feeding the dressed end into the rear nut body and through a floating ferrule retained within the rear nut body; (b) axially realigning the ferrule during said step of feeding to facilitate penetrating engagement by the cable sheath; (c) inserting in circumscribed relationship a mandrel located in the rear nut body within the sheath in juxtaposed relationship with the ferrule during exercise of said step of feeding; (d) threadedly engaging the rear nut body with the front nut body; (e) locating the conductor within a collet in the front nut body during said step of threadedly engaging; (f) radially inwardly compressing opposed ends of the ferrule to grip the sheath during exercise of said step of threadedly engaging; (g) constricting the collet to grip the conductor; and (h) limiting with a mechanical stop the extent of threaded engagement between the rear nut body and the front nut body. - View Dependent Claims (23, 24, 25, 26, 27)
