Description of the invention) [Technical field] (Please read the precautions on the back before filling out this page) The present invention relates to a manufacturing method of a ferrule with a small diameter hole in the center of an optical connector part. [Background Art] The connection of optical fibers such as quartz-based optical fibers includes a method of fusion connection and a method of optical connector. The long-distance communication optical fiber connection uses fusion connection, and the short-distance optical fiber or optical fiber connection uses optical connector 0 optical connector, which requires a small connection loss, even if it is repeatedly loaded and unloaded, the connection loss is stable, easy to load and unload, etc. Features ◦ Also, permanent connection using connectors is also expected to develop in the future. The optical fiber is thin and flexible, so it is easy to cause fiber axis offset, bending, gap, etc. during connection, and these will cause the connection loss. Especially the axis offset system will be the major cause of connection loss. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. Therefore, the optical connector needs to be fixed to prevent the optical connector from shifting. To this end, the optical connector part is a ferrule. That is, the optical connector has a true circular cross-section, and an optical fiber with a diameter of about 1.3 mm is passed through a cylindrical tube to be fixed, and the cores located at the center of the optical fiber are correctly matched to each other for connection. By. The cylindrical tube is a ferrule. The most commonly used ferrules are, for example, the shape shown in Figure 1. ◦ As the material of the ferrules, stainless steel, zirconia, and plastic are used, but chromium oxide is now the mainstream. Figure 1 is a 1-core ferrule, made of a cylindrical tube with a length of about 8 mm, with a perforation of 0 · 1 2 6 mm in the center. -4- This paper size applies to Chinese National Standard (CNS) A4. Specifications (210 X 297 mm) 475074 A7 _B7 5. Description of the invention? ) Hole in true circle shape. Recently, two-core ferrules or multi-core ferrules with more than three cores have been demanding. (Please read the precautions on the back before filling out this page.) To manufacture a ferrule made of zirconia, first, mix zirconia powder and resin, and then shape this into a cylindrical shape. Next, the molded article was thermally decomposed at a temperature of about 500 ° C, JD_decomposition_to_Katsuki ". Purpose i, and was fired at a β temperature of about 12 0 ° C. After firing, the center part of the cylinder was drilled and polished. This polishing operation is performed by hand, and requires the correct size. Since the ferrule made of zirconia is manufactured by the above method, it has many problems as follows. First, expensive injection molding machines and metal molds are required because injection molding machines, extrusion molding machines, etc. are used. In addition, since zirconia powder having a high hardness is formed by a molding machine or a metal mold, the molding machine or the metal mold suffers severe abrasion, and the life of the molding machine or the metal mold is short. Therefore, the manufacturing cost becomes high. As a molding machine, although the countermeasures for the friction of metal molds include special molding machines and metal molds made of hard surface materials, this type of equipment becomes expensive and the manufacturing cost becomes higher. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. Secondly, the resin will be oxidized. The molded product of resin will be processed at a high temperature of 5000 ~ 1200 ° C, so the energy cost will increase. This is also a waste of energy resources. Thirdly, in order to obtain the dimensional accuracy of the central hole, the hole must be polished by a linear diamond polishing body. This polishing is performed by hand using expensive diamond polishing bodies. Moreover, this operation requires a high degree of proficiency. As a result, the dimensional defect rate tends to be high, and the cost becomes high. Fourth, polishing is required for the highly skilled hands of the operators. The paper size is applicable to Chinese National Standard (CNS) A4 (210 X 297 mm) -5-475074 A7 B7 5. Invention description e) low productivity . (Please read the notes on the back before filling this page.) The fifth series is mainly used in the 1st figure of Figure 1 as the mainstream, but gradually requires 2 cores or more. For ferrules for multiple cores, it is very difficult to obtain the precise center of the size of the diamond polished body. Especially for ferrules with more than 3 cores, it is impossible to manufacture. The present invention is based on the problem of conventional ferrule manufacturing, and its purpose is to provide a device that does not require expensive forming machines, metal molds, etc., from simple and inexpensive equipment, low energy cost, good dimensional stability, and easy production management. The skilled worker has a low defect rate and high productivity. It is a ferrule manufacturing method that can be easily manufactured even for multi-core ferrules with more than 2 cores.

Matters before filling out this page) By the present invention, expensive molding machines, metal molds and other equipment are not needed. Generally low-cost equipment for die processing, roller processing, stamping and compression processing, or stamping and drawing processing can produce ferrules with good dimensional accuracy at low cost. Since the skilled workers are not required, the defect rate is low, and the productivity is high. Furthermore, ferrules for multi-cores with more than two cores can be manufactured extremely easily. [Best Mode for Carrying Out the Invention] The principle of manufacturing a ferrule by the present invention is shown in FIG. 2. First, a core wire 2 is arranged in the hose 1, and the inner diameter and the outer diameter of the flexible tube are uniformly modulated by a mold 3 having a predetermined diameter. At this time, it is better to make the front slip agent 4. or off. The hose can be sintered from precious metals such as gold, platinum, rhodium, silver or stainless steel, aluminum, copper, iron, nickel, magnesium, zinc, tin, molybdenum, zirconium, titanium, tungsten, Schmidt or alloys of these. Made of alloy materials, plastics, etc. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs The core wire is made of a material that is harder than the material of the hose, and it is better to have a thin wire with a slightly larger diameter than the fiber through the ferrule. In addition, it is preferable that the core wire is made of a material having high hardness without changing the pressure of the hose material when passing through the die. From this point of view, materials using hard steel wire, stainless steel wire, tungsten wire, titanium alloy wire, nickel alloy wire, etc. are preferable. In particular, hard stainless steel wire, hard steel wire, tungsten wire and other high-hardness materials are suitable for core wires. As the hose material, precious metals or soft stainless steel materials are used. Nickel materials have low hardness and are easy to form and have high corrosion resistance. Suitable for. Use the inner diameter and outer diameter of the hose shown in Figure 2 as a uniform adjustment method. ^ The paper size applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm). 475074 A7 B7 V. Description of the invention e) (Please Please read the precautions on the back before filling out this page.) The example illustrates the method of using the mold, but it is not limited to this. As other methods, roller processing, press compression processing or press drawing processing can be applied. In addition, in order to easily pull out the core wire from the hose in any of these processing methods, it is preferable to apply a surfactant or a lubricant such as soap, oil, resin, or a release agent between the hose and the core wire. FIG. 3 shows a roller processing method. The roller processing method is a processing method of adjusting the inner diameter and outer diameter of the hose by a hose 8 having a core wire 9 with a groove with a radius of the flexible tube made of light to relatively rotate. In this case, it is preferable to use the lubricant 7. Fig. 4 shows a press compression method. Punching and compression processing is a processing method in which a hose with a core wire 11 is placed in the center of a plurality of divided metal molds, and the inner diameter and outer diameter of the punched hose are adjusted in the direction of the arrow. At this time, it is also preferable to use the lubricant 1 2. Fig. 5 shows a drawing and drawing processing method. The stamping and drawing process is a method of adjusting the inner diameter and outer diameter of a hose by pressing a fixed cylindrical metal into a hose 15 having a core wire 1 3 in the direction of the arrow. Also in this case, it is preferable to use the lubricant 14. The Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs printed a uniform hose with an inner diameter and an outer diameter like this, then cut the hose only to a predetermined length, and sequentially cut the hose from the end in order. Pull from the core wire to get the ferrule. The pulling of the hose is to fix one end of the hose that cuts the hose part, and then pull out the hose part in sequence from the other end. The hose can also be cut along with the core wire. When cutting together with the core wire, it is removed by pressing out the core wire. Press the pin into the core, or spray high pressure air, water or oil to remove the core. -9- This paper size is in accordance with Chinese National Standard (CNS) A4 (210 X 297 mm) 475074 A7 B7 V. Description of the invention (7) (Please read the precautions on the back before filling this page) Leave the core wire and cut only When the hose is cut, or when the core wire and the hose are cut at the same time, it can be cut by roller knife, spinning, wire electric discharge cutting, metal sawing, grinding wheel cutting, stamping, laser, electric paddle or hydraulic Cutting and other methods. An example in which the hose portion is cut using a roller knife is shown in FIG. 6. Positioned by spacers with a length equivalent to the length of the ferrule 16, 1, or a plurality of rollers, and for the rotary or parallel-moving roller knife 17 to put the hose with the core wire in, or for the rotary One or more hoses can be cut by putting the cored hose against the roller knife. Fig. 7 shows an example in which a plurality of hoses having a core wire are simultaneously cut by wire electric discharge machining. It is also possible to cut one or more at the same time by rotary cutting, metal saw grinding wheels, etc. Only cut the hose without cutting the core wire, and pull out the cut hose part from the core wire, or press out the core wire from the hose cut with the core wire, which is the marked ferrule. The pull-out of the hose section cut from the core wire is shown in Figure 8 in a pattern. This picture shows one end of the fixed hose, and the hose part 20 cut off sequentially from the other end is pulled out from the core wire 19 in the direction of the arrow. Printed in Figure 9 by the Consumers' Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. When the hose 2 1 is cut with the core wire 2 1, the core wire 21 is pressed out by the pin 2 2. At this time, the core wire can also be removed by grasping and pulling out a part of the core wire that has been squeezed out (Figure 9 (b, c)). Figure 10 is a method of removing high pressure air, water or oil to remove Mode representation. By injecting high pressure gas or liquid from the nozzle 2 5 to the hose 2 10- This paper size applies the Chinese National Standard (CNS) A4 (210 X 297 mm) 475074 A7 B7 V. Description of the invention f) 7 of the core wire 2 6, you can press to remove the core wire. (Please read the precautions on the back before filling in this page) The ferrule obtained by removing the core wire is made of appropriate size or other light-made ferrules, which are made of practically expensive ferrules, as required. The above description is mainly made of a single-core ferrule, but of course, the present invention is also applicable to a multi-core ferrule. The multi-core ferrule is basically manufactured in the same manner as the single-core ferrule described above. · For multi-core ferrules, use hoses with multiple core holes. As shown in FIG. 11, a hose (a) having a plurality of core holes having a predetermined size is inserted into a core wire in advance, and the shell is modulated by a die, a roller press, a compression process, or a pressing process. The inner and outer diameter dimensions (b), after which the hose and the core wire are cut off, and by removing the core wire in the hose, a multi-core ferrule (c) can be obtained. In the case of a multi-core jacket, it can be manufactured in the same way as a single core. At this time, to change the multi-core component, it is necessary to change the shape of the die, the shape of the roller, the shape of the stamping type, and so on. Printed on Figures 12 and 13 by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economy. In order to obtain a multi-core sleeve. Figure 12 shows an example of a 6-core ferrule arranged in a straight line, and Figure 13 shows a 7-core ferrule arranged in a columnar shape. According to, the so-called long ferrule of 1 core means, in short, the state before the hose is inserted into the core wire, and the die is processed. Figures 14 to 17 show examples of multi-core ferrules. Figures 1 and 4 show the arrangement of a 2-core ferrule using straps or casings. Similarly, the 6-core ferrule arranged in a straight line is shown in Figure 15 (a), and row -11-This paper size applies to China National Standard (CNS) A4 (210 X 297 mm) Intellectual Property of the Ministry of Economic Affairs Printed by the Bureau's Consumer Cooperatives 475074 A7 B7 V. Description of the invention e) The 12 cores arranged in a straight line are shown in Figure 15 (b). Figure 16 shows the combination of a 12-core ferrule and a 12-group 1 4 4-core ferrule. Fig. 17 shows a 7-core ferrule arranged in a wall shape. [Industrial Applicability] According to the present invention, it is easy to provide a ferrule and a ferrule at a low cost for a conventional chrome oxide ferrule. The ferrule is the main part of the optical connector, and the connection of the optical fiber for communication is indispensable. The present invention is extremely expensive in the field of communication information industry. Brief Description of Drawings Figure 1 is a drawing showing a ferrule.
