Definitions

  • the present invention relates to an inner housing of a connector, in particular an SC connector, for receiving a ferrule of a fiber optic cable, in particular a POF ferrule, according to the preamble of claim 1.
  • Such inner housings find their use in optical fiber connectors, as they can be seen, for example, from WO99 / 42877.
  • This document describes an optical fiber connector, in particular a standardized SC connector, with an outer housing (hereinafter also called connector housing) and a
  • Inner housing also called ferrule housing or ferrule holder in the following.
  • the outer housing is slidably disposed over the inner housing and serves to be able to solve the Fnnengetude of a Vemegelungsklinke a connecting or coupling piece in a push-pull manner.
  • an inner housing with the features of claim 1 and in particular by means of an inner housing of a connector for receiving a ferrule of a prefabricated fiber optic cable, wherein the inner housing has at least one lateral recess.
  • This lateral recess is designed and dimensioned such that a ferrule of a prefabricated optical waveguide can be inserted laterally.
  • this comprises a rear wall, which is provided with a notch-shaped recess, such that the lateral recess and this notch-shaped recess form a common housing opening for the lateral insertion of a ferrule of a prefabricated optical fiber cable.
  • the inner housing according to the invention is preferably provided with at least one spring element for the axial positioning of the ferrule. This spring element is supported on the
  • Inner housing preferably on the rear wall, and presses the ferrule against a stop surface.
  • a leaf spring pair as a spring element proves to be particularly advantageous because this can be pre-assembled in the factory and because their curvature also leads to the inserted ferrule is securely held in the inner housing.
  • Inner housing at least on the opposite side of the side recess of the inner housing at least one opening for the non-destructive removal of the ferrule mounted in the inner housing. Through this opening, a screwdriver or other suitable tool can be introduced so as to press the ferrule against the spring force of the spring elements from the inner housing.
  • the inventive inner housing can be used as a module part in a variety of connectors and can also be used in particular for a connector housing according to EP application no. 04003701.2.
  • FIG. 1 shows a three-dimensional view of the inner housing according to the invention in the mounted state
  • FIG. 2 shows a three-dimensional representation of an SC connector with an inner housing according to the invention
  • Connector. Fig. 1 makes the structure and operation of the inventive inner housing 1 of a connector 2, 3 clearly.
  • This inner housing 1 has a lateral recess 4, which allows a prefabricated optical fiber cable 5 with its ferrule 6 to insert laterally into the housing.
  • the illustrated embodiment of the inner housing 1 has a rear wall 7 with a notch-shaped recess 8. This rear wall makes it possible to use spring elements, esp. Leaf springs 9, which press the ferrule 6 against a stop surface. This makes it possible to press the end face 11 of the optical waveguide in the coupling against the end face of a corresponding optical waveguide.
  • the inner housing 1 has an extension piece 12 protruding from the rear wall 7, via which a bend protection 13 of a known type can be pushed.
  • this inner housing 1 has at least one opening (not shown) on at least one of its side surfaces, preferably on the lateral recesses 4, for the non-destructive disassembly of the ferrule 6 fastened in the inner housing 1.
  • the leaf spring 9 as well as a coil spring or other elastic element can be used as a spring element 9.
  • the thus equipped inner housing 1 can be inserted in a known manner in an outer housing 14 to form a push-pull connector 2, as shown in Figure 2, to form.
  • Figure 2 shows the Aussenkonture ⁇ a SC connector already used today with POF ferrule and normalized connector face.
  • FIG. 3a the optical waveguide cable 5, which is made up in such a way, is inserted with its ferrule 6, laterally into an inner housing 1 according to the invention. From Figure 3c it can be seen how the inserted ferrule 6 is pressed by means of the leaf springs 9, against a stop surface 10. This spring element allows an axial movement between the inner housing 1 and the ferrule 6 located therein
  • Figure 3d shows the inventive inner housing 1 in mounted State, ie with prefabricated optical waveguide cable 5 and slidable anti-buckling 13.
  • the thus equipped inner housing 1 can now be seen in Figure 3e, in a final step in a standardized outer housing 2, in particular in a SC-RJ duplex connector (see FIG 4).
  • the inner housing 1 according to the invention is suitable for the production of an SC connector 2 (see Fig. 2) for the home, as well as for the production of an industrial SC-RJ connector (see Fig.4).
  • the present construction allows various types of optical fiber cables 5 to be used, in particular, single or multimode glass or plastic (POF) fibers, with step or gradient index may be used.
  • POF single or multimode glass or plastic
  • Disassembly requires no special tools or aids, which allows easy and quick work even by untrained persons. Dismantling can be done non-destructively, i. the item is reusable. Since the inserted ferrule in the coupling in the middle piece resp. Coupling piece is aligned, can be dispensed with complex technical measures for centering the optical conductor. Particularly advantageous is the use of a pair of leaf springs as a spring element, since this can already be pre-assembled in the factory and thus the present in the "field" components can be limited to a necessary minimum.

Abstract

L'invention concerne un boîtier intérieur (1) d'un connecteur enfichable destiné à loger une ferrule (6) d'un câble à fibres optiques (5). Ledit boîtier comporte au moins une cavité latérale (4) et un évidement (8) en forme d'encoche dans la paroi arrière (7) du boîtier intérieur (1). La cavité (4) et l'évidement (8) sont dimensionnés et conçus de telle manière qu'une ferrule (6) d'un câble à fibres optiques surmoulé (5) puisse être logée latéralement dans le boîtier intérieur (1). La boîtier intérieur est pourvu d'au moins un élément ressort (9) servant au positionnement axial de la ferrule (6). Ledit élément ressort s'appuie d'une part sur la ferrule (6) et d'autre part sur la paroi arrière (7) du boîtier intérieur (1).
