Description

 Description Method of manufacturing sleep Technical field

 The present invention relates to a method for manufacturing a sleep used for an optical fiber connector or the like. Background art

 The sleeve has a tubular shape as shown in Fig. 1 and has a slit at the end in most cases because of the passage of objects of various diameters inside, and has a panel elasticity. I have it.

 However, there is a so-called precision sleeve that does not have a slit with improved dimensional accuracy.

 The material used in conventional sleeves is mainly made of zirconium ceramic, and is mainly used to accurately connect ferrules as shown in Fig. 2. I have.

 Zirconia sleeves are manufactured by injection molding using a mixture of zirconium ceramic powder and resin as raw materials, and baking at about 500 ° C to remove resin (degreasing). After that, it is baked at about 130 ° C and then finished with polishing and other finishing.

However, despite the demand for strict inner diameter accuracy, the molded product is subject to high mold shrinkage during sintering during manufacture, and the extremely high hardness of zirconia powder, which adds to the friction of the mold core. The dimensional accuracy is insufficient and the degree of smoothness is also inadequate. Polishing is performed by hand by skilled workers to determine the inner diameter, but the dimensional accuracy is insufficient. Large variation in mating strength with ferrule, mating Productivity was extremely low due to the high rate of poor strength, the need for labor in the inspection process, and the need for manual polishing by skilled workers.

 Moreover, it requires firing at an extremely high temperature of about 130 ° C, uses expensive zirconia powder as a raw material, and uses zirconia ceramics for polishing because of its extremely high hardness. It was extremely expensive because expensive diamond fine powder had to be used.

 In order to solve the problems such as the high cost of Zirco Yua slips, sleeps made of bronze have recently begun to be manufactured.

 In the case of the phosphor bronze sleep, a tube whose center hole is precisely dimensioned is manufactured by pulling it out through a die, and the slit is cut and cut into a predetermined length. It is manufactured by finishing such as barrel processing and chemical polishing.

 In the case of the above manufacturing method, the pipe is easy to manufacture and the cutting process is easy, so that the price can be reduced to a fraction of that of the zirconia. However, the accuracy of the hole diameter at the center is inadequate and inadequate, so the variation in the fitting strength with the ferrule is very large and the rejection rate is extremely high. Due to lack of elasticity, there were major problems in quality, such as a decrease in the mating strength after several detachment tests, and it was not widely used in the industry.

In view of the above, the present invention requires that post-processing such as polishing is required due to insufficient hole diameter accuracy, which is a problem common to conventional sleeves made of zirconia and phosphor bronze, and fitting with ferrules. It fundamentally solves the problem of large variation in joint strength and high defect rate.It also improves the mating strength in the detachment test due to insufficient panel elasticity seen in phosphor bronze sleeves. The challenge is to use easily processable materials to increase productivity and reduce costs significantly. Disclosure of the invention To achieve the above object, the present invention provides

 In the method (1), similarly to the method of manufacturing a metal ferrule by an electrode, the sleeve 1 is manufactured by an electrode method using a rod-shaped object 10 such as metal or plastic as a core. .

 That is, as shown in Fig. 3, electrolytic solution 11, positive electrode 12, holding jig 13, air stirring nozzle 14, panel 15, negative electrode 16, and rod-shaped object 10 are used. . A brass electrode 12 containing nickel balls in a cylindrical titanium paste in a heated electrolyte 11 consisting mainly of heated nickel sulfamate, etc., was placed at four corners around a holding jig 13. With a rod-shaped object 10 such as stainless steel stretched by a spring 15, the rod is fixed around a holding jig 13 with a negative electrode 16, and an air stirring nozzle 14 is set. A small amount of air is blown out of the furnace, and a DC current is applied while stirring to perform electricity.

Electrolyte 11 differs depending on the material of the target electrode metal, but for example, nickel or its alloy, iron or its alloy, copper or its alloy, cobalt or its alloy, tungsten alloy, fine particles Electrolytic metals such as dispersing metals can be used, and nickel sulfate, nickel chloride, nickel sulfate, ferrous sulfamate, ferrous borofluoride, copper pyrophosphate, copper sulfate, copper borofluoride, Copper fluoride, copper titanium fluoride, copper alkanol sulfonate, cobalt sulfate, tandastate An aqueous solution mainly containing an aqueous solution of sodium phosphate or the like, or a fine powder such as silicon carbide, tungsten carbide, boron carbide, zirconium oxide, silicon nitride, alumina, diamond, or a carton. A liquid in which short fibers such as a fiber or various kinds of whiskers are dispersed is used.

 Of these, baths containing nickel sulfamate as the main component are particularly suitable in terms of ease of power supply, variety of physical properties such as strength, chemical stability, and ease of welding. It is desirable to increase the hardness up to about 600 in terms of Vickers hardness by adding an agent, and it is also possible to further improve the elasticity by using a material in which short fibers or whiskers are dispersed. .

 When an object to be joined is a nickel ferrule 3 manufactured by an electrolysis method in the same manner as in the above method 1, it is desirable to use a sleep 1 having a similar composition.

Electrolyte 11 is filtered at a high speed with a filtration system of about 0.1 to 5 m, heated, and temperature-controlled to an appropriate temperature range with a fluctuation range of about ± 3 ° C. the organic impurities were removed by a process, also the anode of the corrugated sheet iron was Nikkerume month, and then the force one carbon to the cathode 0. ² a / dm 2 about energized at a low current density of copper of which the metal impurities It is desirable to keep the electrolyte solution 11 healthy by removing it.

 The positive electrode 12 differs depending on the intended electrode metal, and is selected from nickel, iron, copper, cobalt, etc., and a plate-shaped, spherical, or pellet-shaped material is used as appropriate, and a spherical material is used. In such a case, it is recommended to put it in a titanium basket and cover it with a polyester cloth bag.

 Agitation such as air, propeller, ultrasonic wave, ultra-vibration, or liquid flow can be used for the agitation.However, by increasing the speed of revolving and rotating the holding jig 13 and adding an anti-pitting agent It is also possible to omit the stirring.

The rod-shaped object 10 is made of iron or its alloy, aluminum or its alloy, copper or Metal rods such as alloys, tungsten alloys and the like, thin metal plating on this metal rod, and plastic rods such as nylon and polyester are appropriately selected and used. When using insulating materials such as plastics, metal surfaces such as nickel and silver must be applied to the surface to provide conductivity for rods. Is essential. The rod-shaped object 10 is required to have high precision in thickness, roundness, smoothness, linearity, and the like, and may be manufactured by being combined with extrusion using a die, centerless processing, cutting, and the like.

 The power is applied by the above-mentioned device, and the power is applied by applying a direct current at a current density of about 4 to 8 A / dnf for about 5 hours and a thickness of 0.2 to 0.4. mm, and manufactured in a length of about 400 to 800 mm, taken out of the cell, washed well with water, and dried.

 Depending on the type of rod-shaped object 10 to be selected, it is determined whether it is extruded or extruded or dissolved with a chemical.However, in general, it is difficult to dissolve in a chemical and has high tensile strength. However, for those that are easily dissolved in chemicals, dissolution may be used. For example, in the case of a rod-shaped object 10 made of iron or an alloy thereof, the rod-shaped object 10 may be subjected to a mold release treatment, and after being heated, the rod-shaped object 10 may be pulled out. In the case of the above-described rod 10 made of an electrolessly plated plastic, it may be pulled out by the same method. Of these, a method of extracting or extruding using a stainless steel rod-shaped object 10 which is an iron alloy is particularly desirable.

 In the above-mentioned method (1), the above-mentioned electric power is carried out using a rod-shaped object 10 having a variable thickness (diameter) as shown in FIG. After removal, the sleeves 1 having different thicknesses can be processed as shown in FIG. 4 (b).

With the method shown in Fig. 4, an integrated type that can cope with connection adapters of different thicknesses such as MU ferrule and SC type; It is also possible to produce the sleeve 1 of According to the method (2), a conductive core wire is passed through the hole 101 in the tubular matrix 10 having a hole 101 at the center, and then the electrode is heated. It has a fundamental characteristic in that

 The basic principle of the electrode, the material used, the operation method, and the like are the same as those in the method (1).

 However, in the case of the method (2), since the diameter of the sleep 1 to be manufactured is often larger than that of the method (1), the current density in the electrolyte 11 is (2) In the case of, it tends to be set slightly larger. 'In the case of the above method (2), by changing the thickness (diameter) of the tubular matrix 10, a rod-shaped object 10 of any thickness (diameter) can be used while using the same core wire. It is also possible to manufacture the sleeve 1 whose thickness is changed by both the thickness of the tubular matrix 10 and the thickness of the rod-shaped object 10.

 Although it is theoretically possible to use one piece as the number of tubular masters 10 through which the rod-shaped object 10 passes, in most cases, more than one piece is used. This shows a state in which power is applied after the rod-shaped object 10 is passed through the tubular matrix 10.

 When a plurality of tubular masters 10 are used, a plurality of sleeves 1 can be automatically produced corresponding to the plurality of tubular masters 10, thereby improving work efficiency. be able to.

In the case of the above method (2), it is necessary to remove the tubular matrix 10 and the core wire 20 after performing the electrolysis. In many cases, physical thickness is used, such as drawing or extruding from 10 (of course, it is also possible to adopt a chemical method of dissolving the tubular matrix 10 and the core wire 20). After removing the tubular matrix 10 and the core wire 20, the machine 1 is machined and the sleep 1 is completed. The material forming the tubular matrix 10 is the same as the material of the rod-shaped object 10 in the method (1).

 Usually, the tubular matrix 10 is often made of a metal material. In this case, the tubular matrix 10 and the core wire 20 need to be in contact with each other and to be conductive. When an insulator such as plastic is used as the tubular mold 10, it is necessary to apply metal plating to the surface thereof, and the core wire 20 and the metal plating become mutually conductive. Being connected is essential.

 In the above method (2), it is essential to manufacture a tubular master 10 corresponding to the desired shape of the sleep 1.

 As a typical example of such a method of manufacturing the tubular mold 10, based on the method (1), the rod-shaped object 10 is used as a core, and electric power is applied to the periphery of the rod-shaped object 10. A tubular master 10 made of a metal such as nickel can be formed on the substrate.

 As shown in FIG. 5, the tubular matrix 10 formed in this manner is usually used in a state where a plurality of tubular molds are sequentially passed through the core wire 20. After the object 10 is pulled out, the individual tubular masters 10 are connected to each other and, as shown in Fig. 6, holes 1 are inserted into both ends so that they can be easily inserted when a new core wire 20 is inserted. In many cases, machining using a pin that enlarges 0 1 is performed.

 It is of course possible to further apply electricity to the tubular matrix 10 obtained by the electric power so as to make the electric product a new tubular matrix 10.

 As described above, when the tubular matrix 10 is manufactured by using an electrode, it is indispensable to make the tubular matrix 10 and the sleep 1 newly formed by the electrode separable.

To this end, different metals are selected for the tubular matrix 10 and the sleeve 1 to be newly formed by electric current (for example, phosphor bronze is used as the material of the tubular matrix 10 and a new metal is selected). Nickel is used as the sleep 1 formed by the electrode at the time.) The force or the tubular matrix 10 formed by the electrode is once pulled up from the electrolyte 11, By performing surface processing, the tubular master 10 may be separated from the sleeve 1.

 In the latter method using surface processing, even when the tubular matrix 10 and the slit 2 formed by the electrode are the same metal, both can be separated.

 In the above method (2), since a substantially concentric tubular matrix 10 is formed by an electrode, only the outer surface of the sleeve 1 formed based on the tubular matrix 10 is formed. However, the inner surface also has a substantially concentric shape, so that a sleeve 1 with extremely high precision can be manufactured.

 In the method (2), in order to manufacture the tubular matrix 10 having a variable thickness (diameter), a rod-shaped object 10 having a variable thickness is used, and an electrode is manufactured by the method (1). It can be realized by performing.

 However, the method of manufacturing the tubular matrix 10 having such a change in thickness is not limited to the method using the above-described electrodes, but a mechanical manufacturing method is also possible.

 For example, as shown in Fig. 7, two types of metal pipes are prepared, and one of the thin metal pipes is first processed by a cylindrical grinder or the like to a predetermined outer diameter, and The other large metal tube is press-fitted into the tube, and the entire outer surface including the outer large metal tube is subjected to the surface processing again as described above, whereby a tubular mold 10 having a predetermined shape can be obtained.

 Such a method of mechanically manufacturing the tubular master 10 is capable of efficiently manufacturing the tubular master 10 with a relatively simple mechanical device without using an electric device. Can be.

 Hereinafter, embodiments of the methods (1) and (2) will be described.

[Example 1]

In the first embodiment, in order to uniformly form the concentric sleeve 1, a model using the rod-shaped object 10 of (1) and a tubular matrix 10 (2) of (2) This is a general term for "type.") Specifically, as shown in the plan view of Fig. 8, usually, the holding jig rotation motor 17, belt 18, integrating ammeter 19, pulley 21, jig, fixing structure 22 In a state where the electrolytic solution 11 is put in an electrolytic bath, heated, filtered, and stirred, the positive electrode and all of the individual holding jigs 13 are mixed together with a metal. The electrode 16 is connected to the integrating ammeter 19, a direct current is passed, and the rotation of the holding jig rotation drive motor 17 is rotated by the belt 18 via the pulley 21. The power is transmitted to the holding jig 13 and the holding jig 13 is rotated and turned on, and when a certain integrated current value is reached, the energization and the power based on this are terminated.

 Of course, the use of the integrating ammeter 19 is not an indispensable requirement, but when it is used, a more reliable and uniform sleep 1 can be formed.

 As shown in FIG. 8, by rotating the matrix 10, the electric wall thickness of the sleeve 1 can be made more uniform, and bending of the electric component can be prevented, so that the quality can be improved.

 The rotation speed in the first embodiment is generally appropriate at about 100 to 100 rpm, but is not particularly limited to this number. For example, when a high-speed rotation of 100 rpm or more is adopted, Can omit the stirring for the electrolyte 11.

 Fig. 8 shows the state of rotation, but by rotating the matrix 10 further while revolving, it turns around the cell and eliminates the uneven distribution of metal ions in the electrolyte 11 However, the wall thickness due to the electric power can be made more uniform.

[Example 2]

 Example 2 shows a manufacturing method based on the methods (1) and (2) in the case where the sleeve 1 includes the slit 2.

 As shown in the background art section, usually, a slit 2 is often provided at an end of a sleep 1 in order to smoothly insert an object having various diameters.

However, when the slit 2 is provided by machining, a highly accurate hole 101 can be obtained, but since the appearance of Paris cannot be avoided in the process, the removal of Paris Therefore, barrel processing, chemical polishing process, etc. are required, and there is a fundamental problem in that productivity is low.

 In the second embodiment, the electric insulating member 5 is provided at a predetermined position of the matrix 10 of a rod-shaped object in the method of (1) and (2), and the tubular mold 10 in the method of (2).铸 is performed, and a slit 2 is formed by not attaching metal ions to the position.

 In the second embodiment as described above, each of the masters 10 provided with the electrically insulating member 5 at a predetermined position is supplied with electricity, and the master 10 is removed. Sleep 1 in which event 2 exists.

 FIG. 9 is a matrix 10 for manufacturing a slip between SC types and MU types in Example 2, (a) is a side sectional view, (b) is an A-A sectional view, and (c) ) Shows B-B cross-sectional views, respectively. The conductive tube 110 made of SUS, brass, etc., with the outside diameter of the pore 101 set to the specified size, is made of plastic or other electrical material. Insulating masking member 4 is fixed, and by applying power using this master 10, sleeve 1 in which slit 2 is located in one place is subjected to a post-processing step. It can be manufactured without.

 Fig. 10 shows a master block 10 for manufacturing a sleep that contains a plurality of slits 2 for adapters for connecting ferrules 3 of different thicknesses, for example, SC type and MU type. Is a side sectional view, (b) is an A-A sectional view, (c) is a BB sectional view, (d) is a C-C sectional view, and (e) is a D-D sectional view. An electrically insulating masking member 4 made of plastic or the like is attached to the surface of a tube 110 that has a sudden change in conductive thickness such as SUS or brass with the outside diameter of the pores 101 set to a predetermined size. Fixed.

The masking member 4 of the electrical insulator can be made of a material such as plastic, rubber, or ceramic, and can be covered with a member such as a plastic injection molded product or a vacuum molded product, or can be screen-printed or tambo-printed. Such as various printing methods, masking coating method, A method of forming a film by using a photoresist method or a method of bonding an electrically insulating member 5 can be used alone or in combination.A method using an injection molded product of plastic or rubber can be used. The printing method is more suitable. '' Fig. 11 shows a master mold 10 for the production of a sleeve with several slits 2 for adapters for connecting ferrules 3 of different thickness as in Fig. 10 , (A), (b), (c), (d), and (e) are shown in the same manner as in FIG.

 In the case of the master block 10 shown in Fig. 11, a notch 6 is provided in the metal tube 110 with an accurate width and position from the left and right by wire cutting, etc., and a plastic or the like is inserted into the notch 6. The electrically insulating member 5 is inserted and fixed at a predetermined size, and the masking member 4 made of an electrically insulating silicone rubber or the like is covered with a predetermined size so as to be covered. The electrically insulating member 5 in FIG. 11 can be made of the same material as that of FIG. 10; for example, polyethylene, polyvinyl chloride, polypropylene, polyester, SBR rubber, silicone rubber, etc. Plastics, rubber, etc. have particular suitability.

 When using the metal master block 10 shown in FIGS. 10 and 11, when the DC current is applied in the electrolyte 11 as shown in FIG. The sleeve 1 having the slits 2 at a plurality of locations shown in FIG. 13 can be manufactured with almost no post-processing.

 FIG. 12 shows an embodiment in which a core wire 20 is sequentially passed through a plurality of tubular mother dies 10 based on the above method (2). By using the mold 10, it is possible to efficiently manufacture the sleeve 1 with the slit 2.

In order to realize the embodiments shown in FIGS. 10 and 11, when manufacturing the master mold 10 for manufacturing the sleeve for the adapter, it is usually finished one by one using an NC lathe or the like. Is extremely demanding, and there is a quality problem. In addition, problems such as low productivity and high cost occur due to the difficulty of automation. In such a case, the method of manufacturing the tubular mold 10 described in the above (2) has been described with reference to FIG. (B) As shown in (b) and (b), using a thin metal tube inside and a large metal tube outside and using a cylindrical grinder, etc. Automation can be facilitated and productivity can be improved.

 In the manufacture of the sleep 1 with the slit 2 of the second embodiment, as shown in the first embodiment, the jig for performing the electric power is rotated to manufacture the sleeve 1 having a uniform thickness. That is, of course, possible.

 In the second embodiment, the problem of the generation of pallets as in the conventional sleeve 1 with the slit 2 does not occur, and the sleeve 1 having excellent accuracy in the position and the shape of the slit 2 is provided. It can be produced efficiently.

[Example 3]

 Example 3 shows a manufacturing method based on the methods (1) and (2) when the sleeve 1 has a mesh shape.

 As described at the beginning of the background section, the sleeve 1 usually adopts a tubular shape having a uniform wall thickness as shown in FIG.

 However, in consideration of the original purpose of joining the ferrule 3, the shape is not limited to the above-mentioned shape. For example, a tubular sleeve having a mesh as shown in FIG. 14 is formed. 1 can also be adopted.

 According to the same principle as in FIG. 2, the tubular sleeve 1 having such a mesh is formed by the rod-shaped body 10 by the method (1) or the tubular matrix by the method (2). It can be manufactured by providing the electrically insulating member 5 at the position where the blank portion of the mesh is formed in 10.

As a material of such an electrically insulating member 5, it is possible to adopt a material such as plastic, rubber, ceramic, or the like, as in the second embodiment. In contrast, various printing methods, masking coating methods, photo-resist methods, etc. are used to form a film at the position where a mesh-like blank portion is formed (the position corresponding to the negative of the mesh). A method of bonding the electrically insulating member 5 to the position can be used alone or in combination.

 Of these methods, a method of forming a film by the masking member 4 of an electrical insulator, particularly by a photo resist method, is advantageous in forming an accurate mesh. The sleeve 1 having such a mesh shape can obtain elasticity (paneling) due to the easy deformation of the mesh-like metal wire, and the elasticity increases the fitting strength with the ferrule 3. However, stable bonding can be realized.

 Furthermore, compared to the ordinary sleeve 1 as shown in FIG. 1, the amount of metal material consumed by the electric power is small, which is advantageous in manufacturing cost. Industrial applicability

 In the present invention according to the methods (1) and (2), the productivity of the sleeve can be remarkably improved, and the invention can be applied to various types of sleeves. In the method of (1), when the tubular model is manufactured by an electron gun, it is possible to significantly improve the processing accuracy, particularly on the inner surface.

 Thus, the present invention has multifaceted value, and the value is enormous.
