Optical data connector having magnetic interconnect sensor
First Claim
1. An optical data link for transferring data from a first connector to a second connector while actuating an electrical device connected to said second connector when said first and second connectors engage each other, said data link comprising:
- a magnet mounted in said first connector;
a first optical communication component mounted in said first connector;
a magnetically sensitive switch mounted in said second connector so that, when said first and second connectors engage each other, the magnetic field from said magnet closes said switch, said switch being connected to said electrical device to activate said electrical device when said switch is closed; and
a second optical communication component mounted in said second connector at a position where it is visible to said first optical component when said first and second connectors engage each other, said second optical communication component being electrically connected to said electrical device, one of said optical communication components emitting light as a function of a binary data signal and the other of said optical communication components detecting light emitted by said optical communication component to recover said binary data signal whereby said data signal is transferred between said first connector and said electrical device.

Abstract
An optical data link for transferring data between a pair of connectors and for activating an electrical device to which one of the connectors is attached. A light-emitting diode (LED) and a phototransistor are mounted in each of the connectors, with the LED of each connector visible to the phototransistor of the other connector when the connectors engage each other. The LEDs and phototransistors are connected to respective interface circuits. The interface circuits for at least one of the LEDs limits the current through the LED regardless of the amplitude of a driving signal. The interface circuits for the phototransistors maintain a relatively constant voltage across the phototransistors so that the phototransistors function as current switches. The electrical device is activated in response to closure of a magnetically sensitive reed switch mounted in the connector attached to the electrical device. The switch is closed when the connectors engage each other by the magnetic field generated by a magnet mounted in the other connector.
