Abstract

A device for electro-optical signal conversion having a housing containing electro-optical signal conversion means and electrical and optical contact elements coupled thereto. These electrical and optical contact elements are designed for making contact to electrical and optical connector means, respectively. The housing is provided with latching means for detachably locking the connector means to be coupled thereto. Accordingly, with the device an adapter having an electrical and optical make-and-break connection is provided.

Claims

1. A modular optoelectronic connector assembly for optically interconnecting a fiber optic cable to an electrical circuit substrate comprising:

an optical connector plug for terminating a fiber optic cable having at least one optical fiber, said plug having a housing which includes at one end thereof a protective guide sheath surrounding a termination end of each said optical fiber, a pair of latching spring arms extending along opposite sides of said plug housing towards said one end and having their free ends disposed adjacent opposite sides of said protective sheath,

an optoelectronic adapter for converting optically transmitted data to electrically transmitted data and visa versa, said adapter having a housing which includes at one end thereof a plurality of spaces adapted to mate with said one end of the optical connector plug, a first said space serving as a guide for receiving the protective guide sheath of said plug housing, at least one other space within said first spaced adapted for receiving the termination end of each optical fiber of said plug, and a pair of apertures adapted for receiving and releasably latching therein each of the free ends of said pair of latching spring arms of said plug, said adapter housing having at an opposite end a plurality of electrical contacts and optoelectronic conversion means disposed between said electrical contacts and said one end of the adapter housing, said adapter further having a latching lever extending along one side of the adapter housing with a latching end disposed adjacent said opposite end of the adapter housing,

an electrical connector having a housing with a plurality of electrical terminals disposed therein, one end of each terminal matable with a respective one of said electrical contacts of said adapter, the other end of each said terminal mountable on a circuit substrate, and means disposed on said connector housing for releasably engaging the latching end of said latching lever of the adapter, and

wherein said optical plug and adapter are joined and releasably latched together at said one end of the adapter housing and said electrical connector and adapter are joined and releasably latched together at said opposite end of the adapter housing.

2. The modular optoelectronic connector assembly of claim 1 wherein the fiber optic cable has two optical fibers, and said protective guide sheath of the optical connector plug housing surrounds two optical fiber terminations and said one end of the adapter housing has two said other spaces for receiving each said termination.

3. The modular optoelectronic connector assembly of claim 1 wherein said electrical contacts of said adapter are socket contacts and said first ends of the electrical terminals of said connector are contact pins.
