ABSTRACT:
The present invention relates to a contact connector arrangement for optical waveguides of the internationally standardized SC-type connector whose connection ends are each formed by a male connector.
The highly sensitive connector ends of optical waveguides are readily manufactured for plug-and-socket connection in order to allow their handling. For this purpose the optical waveguides end by way of an anti-kink means in a crimping sleeve and an end ferrule which are enclosed by a male connector.
The problematic aspect in this respect is, however, that such male connectors cannot be used without any further measures for the currently mostly common modular electric connector systems such as RJ 45 or RJ 11, because the cross section of the male connectors does not coincide with the plug-in openings of the electric connector systems.
It is therefore the object of the presention invention to provide a contact connector arrangement for optical waveguides of the internationally standardized SC connector with connector ends which are each formed by a male connector and have the cross-sectional dimensions of modular electric connector systems such as RJ 45 or RJ 11.
This is at first achieved in accordance with the invention by a connector housing receiving at least two male connectors and being used for the manual handling of the plug-in process, which housing cooperates in a positive locking manner by way of coupling means with predetermined plug-in openings of an electric connector system RJ 45 or RJ 11 or the like.
As a result of these measures it is now possible to directly use the connection ends of optical waveguides which are manufactured as male connectors for modular electric connector systems such as RJ 45 or RJ 11, with the in-line arrangement of the coupling means in accordance with the invention further providing a compact design.
A preferred embodiment of the contact connector arrangement in accordance with the invention can be seen further in that the coupling means comprise two substantially similar housing parts which are connected by way of flange means or the like and which enclose means used for establishing contact such as latch means and plug sockets, and further if the housing parts are arranged in a positive locking manner with respect to the predetermined plug-in openings, further if the housing part is used for the detachable insertion of the connector housing with the male connectors on the ends of the optical waveguides, and if further guide grooves are arranged on the housing parts and cam followers on the connector housing and if the connector housing cooperates with the respective housing part by way of catch means.
