Abstract

In a coupler for detachably placing the ends of at least two light waveguides in energy transmitting communication, which coupler is composed of two coupling halves each including a core member provided with at least one precisely positioned bore holding the end of at least one fiber of an associated conductor, a sleeve in which the core member is mounted and which is provided with at least one extension part extending axially of the sleeve, the core having a frontal end face provided with an axially extending guide pin and a guide opening diametrically opposite the guide pin, with respect to the axis of the core member, and a sleeve nut for securing the two halves of the coupler together, each coupling half includes elements supporting the core member to permit the core member to be axially movable in a resilient manner in the sleeve from an end position and to have a limited axial and radial mobility therein, the core member being in its end position when the coupling halves are uncoupled and moving axially from that end position during coupling together of the coupling halves, and structure associated with the sleeve for threadedly engaging the sleeve nut of the other coupling h…
