An adjustable focus connector with spring action is especially adapted for use with common FC or SMA fiber optic receptacles. The connector includes a ferrule holder which mounts a fiber-carrying ferrule at a distal end thereof. At its proximal end the ferrule holder is threadedly connected to a lead screw member. A thrust collar surrounds the ferrule holder and traps a compression spring in the cavity between the thrust collar and the ferrule holder. Because of appropriate interengagement between the components the ferrule holder cannot rotate relative to the trust collar. A traveler is threadedly connected to the lead screw and abuts against the thrust collar. A connection nut is provided at the distal end of the connector to connect it to the fiber optic receptacle. The spring action of the connector prevents damage to the fiber end during connection of the connector to the fiber optic receptacle

Connecteur mâle à ressort ajustable spécialement conçu pour être utilisé avec des connecteurs femelles FC et SMA en fibre optique. Le connecteur mâle comprend un support de férule portant une férule contenant la fibre, situé en son extrémité distale. En son extrémité proximale, le support de férule est vissé à un boulon principal. Une bague d'appui entoure le support de férule et permet de maintenir un ressort de compression entre la bague d'appui et le support de férule. Les composants étant correctement engrenés les uns avec les autres, le support de férule ne peut tourner par rapport à la bague d'appui. Un coulisseau est vissé au boulon principal et vient buter contre la bague d'appui. Un écrou de raccord disposé à l'extrémité distale du connecteur permet de le relier à la prise en fibre optique. Le ressort du connecteur empêche d'endommager l'extrémité de la fibre lors du raccord du connecteur mâle au connecteur femelle en fibre optique.
