Embodiment Construction

[0072] Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. figure 1 It is an enlarged front view showing a cutting blade for processing an optical fiber end face according to an embodiment of the present invention. figure 2 It is an enlarged perspective view showing a main part of a cutting blade for processing an optical fiber end face according to an embodiment of the present invention.

[0073] In the above figure, the cutting edge 1 is provided at the tip of the shaft portion (cylindrical portion) 3. In this embodiment, the cutting edge 1 is formed into a convex semicircular shape by two cutting edges 1a, 1b. In detail, as figure 1 with figure 2 As shown, the tip 2 of the cutting blade 1 is formed in such a shape that the center is a semicircular concave portion 2a, an inclined portion 2b is continuously formed thereon, and is continuous with a vertical portion 2c.

[0074] In the above-mentioned embodiment, th...

Abstract

A plastic optical fiber end surface processing method, a processing apparatus for the method, a cutter for use in the method, and a plastic optical fiber connecting method are provided. The processing method is that at least the core part of the end face of the plastic optical fiber is cut to be formed into a hemisphere face with a half circular cutting blade. The processing apparatus includes: a motor; a cutting blade connected with connecting component or directly to the driving shaft of the motor; a holder having a through hole for inserting the cutting blade into the middle portion of the through hole; a cutter inserted from one side into the through-hole of the holder for cutting at least the core part of the end face of the plastic optical fiber with rotating cutting blade. The invention is capable of processing the plastic optical fiber to be not only convex semi-spherical surface but also concave semi-spherical surface and arbitrary profile according to the change of the cutting blade shape.

Description

technical field [0001] The present invention relates to a method for processing the end face of a plastic optical fiber, which is a method for processing the end face of a plastic optical fiber (hereinafter simply referred to as an optical fiber) such as a convex or concave hemispherical surface, and its processing Devices, cutting blades, and optical fibers are connected to each other, optical fibers are connected to machines, and optical fibers are connected to connecting devices such as connectors, etc. Optical fiber connection methods, especially light guides with little light loss at the connecting part fiber connection method, Background technique [0002] In the past, the method of processing the end surface of the optical fiber into a hemispherical surface was usually a method of processing the end surface after heating. For example, there is a method of keeping the optical fiber in a vertical state, heating its tip with a high-temperature heat source such as a flam...
