Lockable coupling for detachable connection of fiber-optical light guides

摘要

A coupling for detachable connection of a light guide to a coupling counterpart, includes a coupling body that is connected to a light guide frame, a gripping casing that surrounds the coupling body, and at least one locking hook that is movably held in a radially resilient manner for locking engagement behind at least one locking projection of the coupling counterpart, whereby the gripping casing is rotatably supported on the coupling body and the locking hook can be lifted out of locking engagement by rotary movement of the gripping casing. The locking hook is pre-tensioned and held in a locking position in response to an elastic force of a resilient tongue that carries the locking hook. The coupling body merges into the resilient tongue in an axial direction such that an exterior surface of the coupling body and an exterior surface of the resilient tongue are level with each other.

1. A coupling for a detachable connection of a fiber-optical light guide to a coupling counterpart, the coupling comprising:
a coupling body that is connected to a fiber-optical light guide frame with a gripping casing that circumferentially surrounds the coupling body at least in sections, and at least one locking hook that is movably held in a radially resilient manner for a locking engagement behind at least one locking projection of the coupling counterpart, the at least one locking hook being pre-tensioned and held in a locking position in response to an elastic force of a resilient tongue that carries the at least one locking hook and extends from the coupling body, wherein the gripping casing is rotatably supported on the coupling body and that the at least one locking hook is lifted out of the locking engagement by a rotary movement of the gripping casing, wherein the coupling body merges into the resilient tongue in an axial direction such that an exterior surface of the coupling body and an exterior surface of the resilient tongue are level with each other; wherein the coupling body includes an inner thread positioned in an interior of the coupling body proximate to where the coupling body merges into the resilient tongue, the inner thread being configured to screw relative to an outer thread of the coupling counterpart for connecting the coupling and the coupling counterpart.
