F-CONNECTOR WITH DEFORMABLE BODY AND COMPRESSION RING A compression type coaxial cable F-connector (20) includes a conventional coupling nut (38) and tubular post (32). A cylindrical body member (46) is secured to the tubular post and includes a sleeve (52) for receiving the jacket (30) of the coaxial cable (22). A circular relief (62) in the sleeve allows the end of such sleeve to be deformed inwardly toward the cable jacket. A compression ring (64) is mounted over the outer wall (54) of the sleeve of the cylindrical body member and includes a tapered inner bore (74) which forces the end of the sleeve inwardly against the cable jacket as the compression ring is advanced axially over the cylindrical body member. As the end of the sleeve is deformed inwardly, it extends just behind a circular barb (76) formed about the tubular post to pinch the cable jacket therebetween. The compression ring can be manufactured as a separate component, or the compression ring can initially be integral with the sleeve of the cylindrical body member and attached thereto by a frangible connection (102).

Ce connecteur F (20) à compression pour câble coaxial comporte un écrou raccord (38) et un tube (32). Un corps cylindrique (46) fixé au tube comporte un manchon (52) recevant la gaine (30) du câble coaxial. Un relief circulaire (62) du manchon permet à l'extrémité de ce manchon, en se déformant, de se rapprocher vers la gaine du câble. Une bague de compression (64) montée au-dessus de la paroi extérieure (54) du manchon du corps cylindrique comporte un alésage intérieur chanfreiné (74) qui tend à resserrer l'extrémité du manchon vers l'intérieur contre la gaine du câble au fur et à mesure que l'on fait progresser la bague de compression au-dessus du corps cylindrique. Une fois que le manchon est marqué par la déformation le resserrant vers l'intérieur, il vient se placer immédiatement derrière un cran crémaillère circulaire (76) entourant le tube de façon à enserrer la gaine du câble. La bague de compression, qui peut constituer un composant à part, peut également être réalisée dans la masse du manchon du corps cylindrique et y être reliée par une liaison frangible (102).
