What is claimed is: 1. A connector for optical fibers, the connector comprisinga first part for receiving and holding at least one first optical fiber, each of the at least one first optical fiber non-rotatably mounted to the first part, a second part for receiving and holding at least one second optical fiber, each of the at least one second optical fiber non-rotatably mounted to the second part, connection means on the first and second parts for securing them together in non-rotatable relation, an end of each of the at least one first optical fiber adjacent an end of each of the at least one second optical fibers, the connection means comprisingat least one threaded hole in the first part, a hole in the second part corresponding to each of the at least one threaded hole in the first part, and a threaded screw that passes through each of the holes in the second part and threadedly engages the at least one threaded hole in the first part so that tightening of the screw brings the two parts together. 2. The connector of claim 1 whereinthe at least one first optical fiber comprises a plurality of two or more first optical fibers, and the at least one second optical fiber comprises a plurality of two or more second optical fibers and one second optical fiber corresponds to each of the first optical fibers. 3. The connector of claim 1 whereinthe at least one first optical fiber is smaller in diameter than the at least one second optical fiber. 4. The connector of claim 1 wherein each optical fiber has an end portion securely mounted within a hollow ferrule, each ferrule securely mounted in the first part or the second part.
SUMMARY OF THE PRESENT INVENTION The present invention, in one embodiment, discloses an optical fiber connector that includes: a first part and a second part; the first part having a first body member with one or more optical fibers mounted therein and stabilized therein by mounting in a fiber holder such as a hollow tube, each tube extending from the first body member with an adhesive holding the fiber in place in the tube (e.g. epoxy); the fiber or fibers surrounded by a sheath that enters from another end of the first body member, the sheath (e.g., made from co-extruded polyvinylchloride/ polyethylene); at the sheath opening in the first body member an additional supportive sheath (e.g., of polyvinylchloride) may be used for added protection, strain relief, and stability; the second part having a second body member with a recess or recesses therein corresponding to the hollow tube or tubes of the first body member and mounted in each recess an optical fiber corresponding to each optical fiber mounted in the tube or tubes of the first body member; and apparatus such as a bolt or bolts for securing together the first part and second part for added stability.
DESCRIPTION OF EMBODIMENTS PREFERRED AT THE TIME OF FILING FOR THIS PATENT Referring now to FIG 1, a fiber optic probe P is interconnected with a base system B with a multi-fiber connector 2 according to the present invention. The base system B generates an original light ray or rays, receives and measures a change in the analog light signal from the probe P, records the signal, and continuously displays an indication of the signal value. A multi-fiber cable C extends from the probe P to a male part 3 of the connector 2. For example, the cable C may contain six optical fibers in a probe that is about 700 microns in diameter. A tether cable D extends from the female part 5 to the base system B and contains an optical fiber (not shown) corresponding to each optical fiber (not shown) 4 of the male part 3. Knurled screws 6 extend through openings (not shown) in the female part 5 and engage threaded holes (not shown) in the male part 3 to further stabilize the connector 2. At openings 7, 8 of the parts 3, 5, respectively, a sheath 1,9 respectively protects the respective cable and provides additional stability and also strain relief.
