Coupling device for fiber optic cables fitted in plugs

The invention relates to a coupling device for optical waveguides mounted in plugs according to the preamble of claim 1 specified type, after patent application P 30 25 384.0-51.

Such a proposed coupling device solves the problem of reducing the effort in the area of the clamping part and reduce manufacturing costs. In the course of further development, it appears appropriate to change the area of application of this To expand coupling devices in order to perfect the field of coupling devices for optical waveguides.

The invention is therefore based on the object of the coupling device of the type described above with the aim of further developing a cable connection with several optical fibers to manufacture.

According to the invention, this object is achieved by the characteristics of claim 1 specified structural measures solved.

The advantages achieved by the invention are that now an extremely space-saving coupling device for several optical fibers of high accuracy and robustness can be used.

Appropriate training and further developments of the object according to claim 1 can be found in the subclaims.

It is useful if the slots provided are combined in certain areas in order to achieve a favorable floor plan to achieve without impairing the required elasticity (claims 3 and 4). The elastic effect of the between The areas located in the slots and the recesses can be increased by adding the slots at least have the shape of a half circle (claim 5).

An embodiment of the invention is shown in the drawing and is explained in more detail below: The figure shows a coupling device for four optical waveguides, in cross section.

According to this figure, a housing 1 is provided in which there are recesses 2a, b, c, d in a regular arrangement. These recesses are kept essentially cylindrical and serve to accommodate the ends of the optical waveguide. In the center of the housing there is a recess 3 in which pressure bodies 4 are arranged. Various slots emanate from the recess, such as slots 5, which are divided into slots 5 'and 5 "and thus establish a connection between the recess and two recesses. All of the recesses are thus connected to the recess through slots however, two further slots 5a, which are each divided into two slots 5b ¹ and 5b ″ and each enclose a recess at least in a semicircular manner. This creates an elastic area between these slot areas and the recess which exert pressure on the optical waveguide ends by means of the pressure bodies. These optical fiber ends are enclosed in connector pins 6, the actual fiber "with |

7 is marked.

Summary:
■)

The invention relates to a coupling device for optical waveguides mounted in plugs. The task is to extend this technology according to P 30 25 384.0-51 to the use for several optical fibers. The solution consists essentially in an arrangement of several optical waveguide connectors in a housing, in which elastic areas are created through several slots, which can be accessed centrally with the help of a number of slots parent pressure members exert pressure on the optical fiber ξ end. The invention is mainly applied in § of fiber optic technology.
