Ferrule that can be assembled in the field, and associated ferrule housing

Abstract

A ferrule can be assembled in the field. A ferrule collar has a non-circular, in particular polygonal outer contour. A corresponding coding region of a ferrule housing is arranged in a portion of a contact chamber on a cable-connection side and has a non-circular, in particular polygonal cross section, in which the ferrule collar is held with a form fit over the entire spring displacement path. The ferrule spring acts on the ferrule collar over the entire displacement path. As a result, the ferrule is secured against rotation about its axis by a high holding force, which makes it easier for a fibre-optic cable to be screwed on. The structural form is particularly well-suited for use in a plug-in connector module.
