DETAILED DESCRIPTION In accordance with this invention, there is provided an active special contact adapted for insertion into a hybrid contact insert of a connector, the active contact comprising a housing, first contact elements disposed in the housing, a supporting element for receiving an electro-optic transducer, second contact elements provided in the supporting element, means for releasably connecting the housing and the supporting element, and means for releasably connecting the first and second contact elements.
To avoid the disadvantages occurring in the state of the art the invention provides a special contact in which an electro-optic transducer is housed.
The electro-optic transducer may be a diode (transmitter), for instance, or also a receiver.
In general, such a special contact can be called an active special contact as it contains an active electro-optic device.
Due to the fact that the opto-electronic transducer is installed in the active special contact and the special contact is located in a chamber or hole of the hybrid contact insert, a fiber to fiber coupling, i.
e.
the coupling of two light waveguides, can now be avoided.
Furthermore, the solution according to the invention saves space on the chassis or circuit board connected to the contact insert because, after all, the opto-electric transducer does not have to be accommodated on the chassis.
The design according to the invention is also inexpensive and, considering the electro-optic elements or transducers used, completely uncritical regarding offset of the light wave-guide in axial and radial directions and regarding angular offset.
One main advantage of the invention is that the transducer together with its holding means can be removed and replaced when needed (e.
g.
because the electro-optic transducer is defective).
This is also possible without difficulty when a hybrid contact insert soldered into the chassis is involved.
According to one preferred embodiment of the invention, the electro-optic transducer is retained in a metal sleeve crimped to the housing rim of the electro-optic transducer, resulting in a good heat transfer from the heat generating electro-optic transducer to the sleeve so that a greater power loss in the transducer becomes possible
