Optical and electrical hybrid connector
First Claim
1. An optical and electrical hybrid connector comprising:
- (a) a male plug having an elongated plug shaft, said shaft having a first central set of one or more optical fibers terminating in an optical ferrule and a second peripheral set of one or more axial spaced electrical contact elements;
(b) a socket for receiving said plug shaft, said socket having a central axial-position-tolerant optical coupling element having one or more optical fibers and a peripheral set of one or more electrical contacts;
(c) said individual fibers and contacts of said plug arranged so as to make respective optical coupling with corresponding said individual fibers and electrical contacts of said socket when said shaft is slidably and completely received into said socket.

Abstract
An improved hybrid connector for rapidly, reliably, and reversibly making mixed optical and electrical connections has a plug (103) with one or more centrally located fiber-containing optical ferrules (108) and one or more peripheral electrical contacts (109), and second, a socket (105) with interior electrical contacts (115) and a fiber-bearing central floating optical connector (225). Insertion and rotation of a shaft (107) of the plug into a bore (201) of the socket connects the respective electrical contacts of the shaft and socket, and nearly-simultaneously couples the respective optical fibers of the plug ferrule and socket connector, thus creating a rapid, reversible, and low-cost hybrid connection optimized for both the electrical and optical requirements of a mixed optical and electrical connection.

10. A medical illuminator catheter comprising:
-
(a) a biocompatible catheter sheath, said catheter sheath having a monitor end, a central body, and a patient end;
(b) an optical and electrical hybrid male plug located at the monitor end of said catheter;
(c) a light source at the patient end of said catheter;
(d) at least one optical collection fiber for collecting light scattered from a region illuminated by the light source and for transmitting said collected light from said patient end of the catheter, along a length of said catheter and into said male plug at the monitor end of the catheter; and
(e) power supply wires for transmitting electrical power to said light source, said wires traversing a length of said catheter and electrically connected to both said light source and to contacts on said connection plug.

11. A hybrid electrical and optical coupler, comprising a first member having an elongated shaft, said shaft having a central core of one or more optical fibers and a peripheral array of one or more electrical contact elements, each said fiber terminating in an optical ferrule, a socket for slidably and insertably receiving said elongated shaft, said socket having a central axial-position-tolerant optical coupling member and one or more electrical contacts whereby after insertion of the shaft into the socket said shaft optical fibers and electrical contacts make contact with said axial-position-tolerant optical coupling member and said socket contacts.
