The collar 12 penetrates the center hole of the inner flange Ue of the plug frame π, and the outer flange 12a of the collar 12 touches the inner flange lle to prevent the collar 12 from moving to the right side of the paper.芈 (CNS) τ 4 specification (2 丨 0 X 297 rule A β Μ 6 5. Description of the invention (2 ·). The inner flange lle of the plug frame η is located at the opening (right end) and the rear end (illustration) (Left end) is slightly in the middle of the opening. The rear end opens into the front end of the retaining ring 7, and the compression coil spring 14 pushed by the front end pushes the sleeve 12 to the right, so the outer flange i2a of the collar 12 is pushed inward. The flange ue often imparts a rebounding force to the right side of the collar 12. On the outer peripheral surface of the retaining ring 7, a groove is formed in parallel with each other to produce a ring-shaped protrusion on the outer peripheral axis of the cylinder—a pair of half-moon-shaped protrusions. 7a and 7b respectively enter the slot-shaped holes 11a and 11b of the plug frame 11. Therefore, the stop ring 7 and the plug frame are integrally formed.

As shown in FIG. 24b, the plug frame 11 and the retaining ring 7 are integrated. Figures 25a. To 25d show the sequence of fixing the connector to the optical fiber cable 19 as shown in Figure 24b. First, in this order, the optical fiber cable 19 is passed through the rubber cover 20, the pressing ring 21, the riveting ring 22, the retaining ring 7 and the coil spring 14 (Fig. 25a). Then, the outer cover of the front end portion of the optical fiber cable 19 is removed, and the tensile strength wire 23, the core wire 10 and the fiber baseline 9 are exposed (FIG. 25 b). Then, apply an adhesive to the optical fiber base line 9 to pass through the fiber through-holes of the ferrule 12 (material type stainless steel) and the ferrule 12 into one body, and polish and repair the end face of the ferrule 12 (Fig. 25c). Then, insert the ferrule 12 through the hole ll of the inner flange of the plug frame 11 and insert the coil spring 14 into the rear end of the plug frame Π. The ferrule 12 supports one end (right end) of the coil spring 14 with the plug frame π, While pushing the other end (left end) of the coil spring 14 with the retaining ring 7, insert the front end (right end) of the catch ring 7 into the rear end opening of the plug frame 11 so that the meniscus protrusions 7a, 7b of the supporter 7 are engaged with The slit-shaped holes 11 a and lib of the plug frame 11. Secondly, the tensile strength line 23 is folded and arranged on the retaining ring 7. After the outer peripheral surface of the rear end portion, the riveting ring 22 is shifted to the outer peripheral surface of the ring 7 and the tensile strength line 23 is pressed against the willow ring. 22 will be connected, so that the ring 22, the tensile strength line 23 and the escape ring 7 are integrated. Secondly, place the front end (right end) of the jacket 19a on the outer peripheral surface of the small diameter rear end (left end) of the riveting ring 22, and shift it toward the right (please read the precautions for the back first. # 锅 写 ·· ®: IMCHS standard for home use in this paper scale) Specification (210X297 male; ¢) A 6 __________ Ιί_6 _____ V.

The ring 21 is positioned on the outer peripheral surface of the small diameter rear end of the ring 22, and the riveting pressure ring 21, The ring 21, the outer sleeve 19a, and the swaging ring 22 are integrated. Then, the rubber cover 20 is shifted to the right clad ring 22. The above can obtain the optical fiber cable 19 with a connector. Figure 25d shows its appearance. The handle 15 is installed as needed. As shown in FIG. 25d, by inserting the plug frame 11 of the connector into the rear end (left end) of the handle 15, the handle 15 is a slightly flexible synthetic resin, and the inner space is pushed away due to the pressing. As shown in FIG. 24b, the handle 15 and the plug frame 11 are integrated. There are two known methods of inserting the plug frame 11 into the retaining ring 7. The first method is to align the slit-shaped holes ua and llb of the plug frame Π with the half-moon protrusions 7a and 7b of the stop ring 7, that is, use the relative position relationship shown in FIG. Push into the plug frame 11. At this time, if the plug frame 11 contacts the inclined surface of the meniscus protrusions 7a, 7b, that is, the U-shaped two slits 11c facing each other expand the plug frame with its elasticity, allowing the meniscus protrusion to enter the 'protrusion 7a, 7b goes straight to the slit-shaped holes ua and 11b as before.

In addition, it is also familiar with not a sleeve type but a screwed fixed retaining ring 7 and the method of the plug frame 11 (Japanese Patent Application Laid-Open No. 61-129605). Since the above-mentioned conventional optical fiber cable with connector is composed of many parts such as a rubber cover 20, a pressure ring 21, a riveting ring 22, a retaining ring 7, a coil spring 14, a collar 12, and the like, the cost is increased. The rear side of 7 is attached with a riveting ring 22, a pressing ring 21, a rubber cover 20, and the like to implement connection with the optical fiber cable 19, so there is a problem that the connection is troublesome and takes time. Printed by the Central Government of the Ministry of Economic Affairs, A Industrial Consumers Cooperative, and after pressing the stop ring 7 straight into the plug frame Π in any of the first and second methods of combining the stop ring 7 and the plug frame 11, Check whether the meniscus protrusions 7a, 7b of the retaining ring 7 are connected to the plug frame 1; [slit-like holes 11a, lib, or to align the meniscus protrusions 7a, 7b with the slit-like holes 11a, lib, In a relative manner, the stop ring 7 and the plug frame 11 are rotated around the central axis of the plug frame π. However, even if the meniscus protrusions 7a, 7b do not match the slit-shaped holes 11a, lib, the restoring force of the plug frame Π is still pressed and the meniscus protrusions 7a, 7b require a strong force for rotational driving. On the one hand, if the meniscus protrusions 7a, 7b are connected to the slit-like holes ua, lib, the meniscus protrusions 7a, 7b cannot be separated from the slit-like holes 11a, lib unless they are rotated with a strong force. However, this force and the difference in force required to rotate the meniscus protrusions 7a, 7b into the slit-shaped holes na, nb are small. Therefore, in order to confirm the engagement of the stop ring 7 and the plug frame Π, they are relatively excessively rotated. On the contrary, the retaining ring 7 and the plug frame 11 may easily cause assembly errors such as dislodging the meniscus-shaped protrusions 7a, 7b from the slit-shaped holes 11a, 11b, or leaving them as they are.

Therefore, the stop ring 7 is detached from the plug ring 11 and it is easy to produce Obstacles such as broken core wire 10 or broken core wire 10 or optical fiber baseline 9 Such as the polymer-coated optical fiber cable, although it has the full advantages of the aforementioned optical communication cable, but because the entire cable system uses so-called quartz, plastic, resin The organic system polymer is made of a material with low mechanical strength, so it only shows very little resistance to deformation such as stretching, lateral pressure, bending, etc. Therefore, it contains Kepler or higher strength plastic (polytetrafluoroethylene, FRP). Etc.) in order to improve the strength of the linear body. Especially high-stranded people sometimes require extremely high tensile strength, instead of high-strength plastic linear body, sometimes use steel wire. Indispensable elements for signal transmission Is the aforementioned heart line, but If you use steel wire, it becomes a thick and heavy cable. The metal tube covers the optical fiber cable. The core wire is passed through the metal tube. It has high resistance to stretching, side pressure, bending, etc., and it is thinner and lighter. Because of the small radius, it is not easy to bend, and it is not easy to break the cable that causes the core wire to break, so it is easy to handle and easy to do the cable wiring, that is, the wiring. ©: For metal tube coated optical fiber cables, seamless tube packages are sold on the market.

The advantage of seamless tube-clad fiber optic cable is that it completely breaks the core wire from its external environment, but is less flexible than the flexible tube-clad fiber optic fiber. -On the one hand, the tightness of the flexible tube covering the optical fiber is not good. Therefore, recently, for most of the distance of the optical communication cable wiring, the seamless optical tube is used to cover the optical fiber electric fiber, and the above-mentioned method is connected to the connector. That is to say, in places where it is necessary to bend more flatly than d, * jin, the flexible tube-coated optical fiber cable is connected to the seamless-coated optical fiber cable between the adapters. Metal tube coated fiber optic cable has important disadvantages in terms of insulation. That is, the optical fiber core wire insulation is coated inside, so although it will not cause signal obstacles when it comes into contact with live and wire wires, the outer metal pipe is a good conductor, which is equivalent to the connector installed at the end of the metal pipe. Pass current to a machine or device. Sometimes this machine can damage the machine or equipment. Therefore, it is best to cover the metal pipe with an insulator such as an organic polymer. However, if the coating is thickened, the flexibility of the cable is reduced and the weight of the cable is increased. If the thickness of the coating is reduced, the coating will be damaged due to repeated bending / stretching or hitting things. [Summary of the Invention] The first object of the present invention is to provide a metal tube-coated optical fiber cable that has high mechanical strength and is unlikely to cause internal fiber core wire damage. The second object is to prevent current from flowing into the metal tube-coated optical fiber with a connector. For cable-connected machines, the third objective is to reduce the number of parts of the fiber-optic cable covered with the connector metal tube and simplify the connection between the cable and the connector. The fourth objective is to do the connection of the connector to the electrical connector. Not easy to leave. The metal-clad fiber-optic cable according to the first aspect of the present invention is prepared to be combined with the limited size of this paper. A-Λ 6) 发明 6 V.

In addition, the symbols in parentheses show the response to the first embodiment (Fig. 1) described later in the figure. Factors or corresponding matters. According to it, since the base (11, 15) is an insulator, It can obtain a high degree of insulation with the machines and equipment connected to it. For example, as long as it is in contact with other live wires, it will not cause current to flow into the machine and equipment to damage the machine and equipment. Moreover, due to the fiber optic system It is covered with a metal tube, so it is lightweight and has high strength. Therefore, it is possible to obtain a highly secure optical fiber cable.

Description of the invention (14.) and the base line of fiber made from metal cladding 9 Optical fiber core wire 10 Through seamless pipe 4, adapter 5, flexible pipe 6, adapter 7 and fixed nut 8. In addition, flexible pipe 6 has the property of maintaining straightness and verticality in the longitudinal direction. The connector has a cylindrical shape. Body 11. The body 11 is inserted into the collar 12 at the front and the collar 13 is inserted at the rear. The front end of the collar 12 protrudes from the body 11. The compression coil spring 14 is inserted between the collar 12 and the collar 13. The sleeve The ring is splined to the body 11, and the flange of the collar 12 touches the inner flange Πa of the body 11. The body 11 penetrates the connection nut 15. The connection nut 15 shown in FIG. 1 is bolted A metal connection adapter 2 fixed to a communication device (not shown) is connected. Due to the screw lock, the inner flange 15 a of the connection nut 15 touches the outer & The body 11 is fixedly locked to the connection adapter 2. The female bolt of the fixed nut 8 is combined with the male bolt 11c on the outer periphery of the rear end of the body 11, and the collar 12 is located at the connection adapter due to the rebound force of the compression coil spring 14 The communication device side collar 120 at the axis 2 position of the transmitter is pushed, and the front end surface of the collar 12 is closely attached to the front end surface of the communication device side collar 120. For the baseline 90-axis center fixed to the collar 120, it is necessary to match the baseline 9-axis center fixed to the collar 12 with a degree of precision of ~ 2 #. Between the metal tube of the cable, that is, between the flexible tube 6 and the communication device connection adapter 2 ', there is an adapter 7' fixed nut 8 and the body; q. In the first embodiment, an insulator (in this embodiment, a polycarbonate having abrasion resistance and high strength) is used to form the body 11, the collar 12, and the connection nut 15. That is, in the insulator body 11, the electrical connection from the flexible pipe 6 to the mechanical coupling of the adapter 2 is broken. Therefore, it is assumed that an abnormal current does not flow to the connection adapter 2 through the flexible tube 6. In addition, the above-mentioned insulation system has a volume-specific electric capacity of 1 paper size, and is used in the aa home standard (CNS) specification (210x297g; 1J :) ~~ _ Λ 6 Π 6 V. Description of the invention (15.) Resistance (relatively full 50%, 23 C) > 1〇13 ω cm and piezoelectric resistance (short time method, thickness 3.17 coffee) > 1001 ^ / 〇11, for the body 11 shown in FIG. 1, the collar 12 Although the connecting nut 15 is made of polycarbonate having abrasion resistance and high strength, other resins, ceramics, or a mixture of these materials may be used. For these parts, a certain degree of mechanical strength is required. For example, the tensile strength of the mechanical strength is preferably 15 kgf / crrf or more. In the first embodiment, although the seamless tube cable 19 A and the convertible tube cable 19 B are used in combination, the present invention is not limited to these, and only the seamless tube cable 19 a is used to directly fix the adapter 7 to this item. Alternatively, the present invention can be implemented using only the flexible tube cable 19B. Furthermore, in the embodiment shown in Fig. 1, the ferrule 12, the connection nut 15 and the body 11 are used as insulators, but instead of being shown in Fig. 2, a fixed nut 8 may be used as an insulator. In the first modification shown in Fig. 2, the fixed nut 8 is made of glass fiber filled with a formaldehyde resin. Furthermore, as shown in FIG. 3, the adapter 7 may be used as the insulator 6. In the second modification shown in FIG. 3, the adapter 7 is made of polyethylene. Although not shown in the figure, it is preferable that the ground point is installed in a metal pipe near the insulator or in a part that is electrically connected. The Central Bureau of Standards, Ministry of Economic Affairs, Japan, Japan, Japan, Japan, Japan, Japan, Japan, Japan, Japan, etc. Fig. 4 shows a third modification of the first embodiment. In this example, the insulator adapter 16 connects a flexible tube cable 19B to the body 11. That is, instead of the adapter 7 and the fixing nut 8 shown in Fig. 1, a form adapter 16 is used in which both are integrated. To endure repeated attachment and detachment of the connector, the connection adapter 2, the collar 12, and the connection nut 15 are made of metal. In this example, the adapter 16 is made of polyethylene to prevent the abnormal current of the flexible tube 6 from flowing to the connection adapter 2. For example, according to this paper, the standard (CNS) standard (2) 〇 \ 297 male dragon), the description of the invention (16.) 3 changes ’’ means that the number of connectors is small. Fig. 5 shows a fourth modification of the first embodiment. In this example, the fixed nut 8 shown in FIG. 1 is changed to have the rear end of the seamless pipe fixed by riveting "3 a. Figure 5 shows a form of use because the connector is connected to the convertible tube 9B Therefore, the function of the sleeve 8a for riveting is not used. Fig. 6 shows a fifth modification. It shows another use shape shown in Fig. 5: Here, the seamless tube 4 is fixed by riveting the sleeve 8a. The fixed screw is 8 meshes. Therefore, the connector shown in FIG. 5 is not only a flexible pipe cable 19B, but also a seamless pipe 4 (FIG. 6). In addition, the fixed nut shown in FIG. 5 and FIG. 6 8. Although it has a metal spoon ta, as shown in Figure 7 or Figure §, the fixed nut 8 can also use the screw head 8b or 8d and the metal material rivet fitting 8c or 8e as basic parts, and those as It is made by bolting or pressing into one. As shown in Fig. 7 and Fig. 8, if the nuts 8b and 8d are used as insulation, the nut 11 and the body 11 shown in Fig. 5 can be combined with the nuts 15 and The ferrule 12 is made of a metal material. In the example shown, the thickness of the seamless pipe 4 is a small thickness of the riveting fitting 8c and the thickness of the riveting fitting 8e. The degree is 0,4 mm. When the seamless pipe 4 is fixed by riveting according to accessories & such as, the seamless pipe 4 has a strong strength against deformation such as stretching, lateral pressure, bending and the like. Due to the sleeve 8 &, 8c, 8e The fixed nut 8 can be used for riveting metal pipes (Figure 6) and those who do not need riveting (Figure 5), so the connector with it is widely used. It is not ideal to form riveting accessories 8c and 8e with insulation. [Second embodiment] Referring to FIG. 9a showing the second embodiment of the present invention, a flexible tube cable can be used. 5. Description of the invention (17.) The optical fiber baseline 9 of 19B penetrates the ferrule 12 and is fixed to the ferrule 12 The diameter of the optical fiber base line 9 is about 125 m. The core wire 10 enclosing the optical fiber base line 9 with a thin resin coating is also fixed to the ferrule 12. The ferrule 12 penetrates the center of the inner flange lie of the plug frame u. The hole, because the outer flange 12a of the ferrule 12 hits the inner flange e, prevents the ferrule 12 from moving to the right. The inner flange 116 of the plug frame 11 is located at the front end (right end) and the rear end (figure (Shown at the left end) is slightly in the middle of the opening. The rear end opens into the front end of the retaining ring 7 and is pushed by this front end: the coil spring 14 is compressed and the collar 12 is pushed To the right, the outer flange 12 & of the collar 12 is displayed on the inner flange lie.

Fig. 9b shows the outer appearance of the circling ring 7 and the plug frame η shown in Fig. 9a, and Fig. 9c shows the front face of the retaining ring 7. The outer peripheral surface of the baffle ring 7 has half-moon-shaped projections 7a, 7b protruding from the outside, and between these projections 7a, 7b and the front end surface, there are two non-rotation projections 7C, 7d extending to the axial direction. The non-rotation projections 7c and 7d are located in the middle of the meniscus projections 7a and 7b. The plug frame n has slit-shaped holes 11a and 11b that receive the meniscus-shaped protrusions 7a and 7b, and cuts and receives the meniscus-shaped protrusions 7c and 7d, and the two opposite long holes that are continuous to the rear end opening, that is, the slit 11c. For example, if the non-rotation protrusions 7c and 7d are aligned with the slit lie, the front-end cylindrical portion is inserted into the rear end of the plug frame 11 from the half-moon protrusions 7a and 7b. Since the outer diameter of the half-moon protrusions 7a and 7b is larger than the rear end The insides of the openings, so these will hit the rear opening edge of the plug frame 11. If the retaining ring 7 is re-inserted as usual, the rear end opening of the plug frame 11 is pushed away by the meniscus protrusions 7a, 71) to open the slit lie, and the meniscus projections 7a, 7b enter the rear opening of the plug frame 11, The front end surface of the stop ring 7 hits the plug frame; the rear end of q is open at the bottom, and the half-moon protrusions 7a and 7b enter the slit-shaped holes 11a and lib of the plug frame 11 due to the elastic restoring force of the plug frame 11. The slit; and the rear end opening gradually narrows so as to be slightly closed, as shown in FIG. 9a, combining the plug frame 11 and the retaining ring 7. In this combined state, because the end faces of the notches of the meniscus projections 7 & 7b touch the short-side inner surfaces of the holes 11a, lib, and because the stop projections 7c, 7d are blocked by the slit lie, the stop ring 7 cannot be rotated . In particular, the rotation-resistant protrusions 7c, 7d and the slit lie have high rotational strength. As for the force in the direction of extracting the retaining ring 7 from the plug frame, the coupling strength of the meniscus protrusions 7a, 7b and the slit-shaped holes 11a, lib is high. As long as the rear end opening of the plug frame π is not pushed away, the stop cannot be extracted. Ring 7.

For example, if the guide grooves 7g and 7h of the stop ring 7 are aligned with the tongue nh of the plug frame 11, the jaws 11 j and Ilk of the plug frame 11 are inserted into the plug frame 11, that is, First, push the claws Uj, llk outward on the bottom surfaces of the guide grooves 7g, 7h to open the tongue 1; ι1, Hi slightly to the outside, and guide the claws lij, nk with the grooves 7g, 7h. Then, since the outer diameter of the meniscus protrusions h, 7b is larger than the inner diameter of the rear end opening, these things will hit the rear opening edge of the plug frame u. If the measure 7 is inserted again, that is, the rear end opening of the plug frame 1; 1 is pushed by the half-moon projections 7a, 7b so as to open the slit lie, and the half-moon projections 7a, 7b enter the rear opening of the plug frame U.

Description of the invention (20 ·) The holes 11a, Ub are gradually narrowed due to the elastic restoring force of the plug frame 11 so as to slightly close the slit 11c and the rear opening, combined with the plug frame u and the retaining ring 7. At the same time, the claws 11j, Ilk enter the holes 7i at the rear ends of the grooves 7g, 7h, and gradually narrow due to the elastic restoring force of the tongues Hh, 11i to close these slightly, and the tongues 11h, li just fit into the grooves 7g, 7h. In this combined state, the end faces of the notches of the meniscus protrusions 7a, 7b touch the short sides of the holes na, lib, and the tongues llh and lli are inserted into the grooves 7g and 7h and the claws Uj and Ilk are inserted. Hole 7i, and the retaining ring 7 cannot be rotated. As for the force in the direction of extracting the ring 7 from the plug frame 11, since it can withstand the coupling of the meniscus projections 7a, 7b and the slit-shaped holes 11a, Ub, and the coupling of the claws Uj, ilk, and the hole 7i, as long as it is not pushed Open the rear end of the plug frame 11, that is, the retaining ring cannot be pulled out. 〇 The staff of the Ministry of Economic Affairs, the Central Bureau, and the Prospective Bureau may cooperate to print any of the first modification and the second modification of the second embodiment. The half of the rear end side of the plug frame 11 is a quadrangular shape. Therefore, as shown in FIG. 12, the outer shape of the meniscus protrusions 7 a and 7 b (FIGS. 9 b, 10, and 11 a) can also be made into a quadrangular shape. In addition, FIG. 12 is a front view showing the front end surface of the escape ring 7 according to FIG. 9c. Therefore, if it is formed in a quadrangular shape, the resistance to the rotation of the stop ring 7 is enhanced by the combination of the protrusions 7a, 7b and the slit-shaped holes 11a, lib. According to the second embodiment and its modification described above, since the number of parts is reduced compared to the conventional case (Fig. 24b), the cost is reduced, and the connection work of the metal fiber optic cable and the connector can be simplified. After the connection is completed, although a rotational force or a tensile force is relatively generated between the plug frame and the retaining ring, since it can tolerate its high strength, the two will not be separated.

Explanation of the invention (21 ·) [Description of the flexible tube 6] Ministry of Economic Affairs Printed by the Central Bureau of Standards, Bureau of Industry and Engineering Cooperatives 5ί Figure 13a shows the first and second implementations described above, and the flexible tube 6 spiral coil 1 pitch used in these modifications, hereinafter referred to as "1 pitch member ". The 1-pitch member is formed by the large-diameter portion 64 and the small-diameter portion 67. The large-diameter portion 64 has a first annular end portion 65 protruding from the small-diameter portion 67 at one end. Similarly, the small-diameter portion 67 is at one end. The portion includes a second annular end portion 68 that protrudes from the large-diameter portion 64. The large-diameter portion 64 and the small-diameter portion 67 are then connected via an annular connection portion 69. Then, as shown in FIG. The tube axis direction and the spiral shape connect adjacent members 63. At this connection portion, the second annular end portion 68 is located in the large-diameter portion 64 of the adjacent member 63 and is actually connected to the first annular end portion 65. Adjacent members 63 are displaced to the tube axis direction. The first annular end portion 65 and the second annular end portion 68 are located outside the small-diameter portion 67 and inside the large-diameter portion 64 of the adjacent member, respectively. There is a gap L1 between the connecting portions 69 in the shape of a ring. Further, the inner diameter of the first annular end portion 65 is increased so that a gap L2 is generated from the outer diameter of the small diameter portion 67, and the outer diameter of the second annular end portion 68 is reduced from The inner diameter of the large-diameter portion 64 generates a gap L2, and the minimum bending radius of the flexible pipe 6 can be adjusted according to the size of the gap L2. As shown in FIG. 14, the flexible pipe 6 is pressed by a metal strip plate 60 with a press. The cross-section S-shape is used as the concave-convex strip body 61 ', which can be obtained by rolling the strip body 61 into a spiral. The first and second annular end portions 65 and 68 and the connecting portion 69 are easily press-processed and improved. For the contact between the first and second ring-shaped ends, the booklet should be tilted so as to conform to the pitch angle of the spiral. As shown in FIG. 15, at a distance of 75cm, 6A and 6B can be kept horizontal around the pipe 6, and then As shown in Figure 16a (side view) and Figure 16b (plan view), a large radius 1 loop L is formed on the flexible tube 6, such as _ 17 & 2 ΚΙ X 297 公; !! :) Λ () ~~ _______ Π_6_ V. Description of the invention (22.) Plane view) and Figure 17b, the horizontal direction of the flexible pipe 6 is provided. If the force is gradually increased to reduce the loop radius, the flexible tube 6 can finally not maintain the loop. The loop is opened as shown in Figure 18a (side view) and Figure 18b (plan view). Therefore, the radius r of the loop before opening is called "loop "Release radius". The thickness of the strip plate 60 is thick, the strip plate 60 is hard, or the larger the flexible pipe diameter, the larger the loop clearance radius r. It is best to set a loop clearance of 15 mm or more in the fiber core 10 The radius r, so as not to add praises above its allowable radii of radius. The Ministry of Economic Affairs and the Central Bureau of Standards printed only one consumer cooperative. On the one hand, as shown in FIG. 19, the flexible pipe 6 is maintained at positions 6c and 6D at a distance of 75 cm as Level, and then as shown in Fig. 20a (side view) and Fig. 20b (plan view), if the compressive force is provided to the flexible pipe 6 and gradually approaches the holding points 6C and 6D, the flexible pipe 6 will sag into a U-shape, and then The twisted U-shaped portion M shown in Fig. 21a (side view) and Fig. 21b (plan view) is shown in Fig. 22a (side view) and Fig. 22b (plan view). When the U-shaped part IV [the radius of the arc of the XJ-shaped part M when the degree of distortion of the direction of the additional compressive force is M is called the "forming loop radius", the thickness of the strip plate 60 is thin, the strip plate 60 is soft, or the flexible pipe diameter is small, or The smaller the overlap of the first annular end portion 65 and the second annular end portion 68 is, the smaller the loop half-r is. The smaller the loop radius R is, the higher the flexibility of the flexible tube 6 is, and the easier it is to guide the wiring in the box. It is best to set the loop radius R to 2000 or less. 9 The inner diameter of the flexible tube 6 is larger than the optical fiber. The outer diameter of the core wire 10 is relatively large, and the core wire 10 can be easily moved within the tube 6. Due to the force to be recovered straight from the spiral of the material strip 61 (Fig. 14), a tensile force is generated in the flexible tube 6 along the axis of the flexible tube 6, so the tube 6 is expected to recover straight. For example, if the flexible tube 6 is not produced on this paper, it will be used in the "Hardware Standards (CNS) Standard (2 丨 0X297)." ) When an external restraining force is generated, as shown in FIG. 13b, the first annular end portion 65 and the second annular end portion 68 are contacted. Therefore, if a compressive force action in the axial direction is generated, the force is reduced, but a tensile force is generated. The effect will not extend. If the bending force is added to the flexible pipe 6, it is bent as shown in FIG. 23, but the first annular end portion 65 and the second annular end portion 68 are in firm contact with each other on the outside of the bend, and are separated from each other on the inside, so the tube 6 The curved outer side does not extend, but it shrinks the inner side. That is, since the total length of the tube 6 has no actual change, and the inner diameter of the tube 6 is considerably larger than the outer diameter of the core wire 10, there is actually no effect of tension and tension in the core wire 10 in the tube 6.

Optical fiber cable 19 A has high strength, small diameter, light weight and high air tightness. Therefore, it can endure high extension line load during cable installation, and it has high mechanical strength, touch resistance and air tightness after installation. On the other hand, since the flexible tube fiber optic cable 19B connected to the connector for short-distance wiring has high flexibility and high mechanical strength, the optical communicator's own station is suitable for use in China.

It is easy to connect the device or other cables, and the cable strength at the connection place is also high. In addition, regardless of whether the seamless tube fiber optic cable 19A or the flexible tube fiber optic cable 19B is used, the optical fiber core wire 10 is not in close contact with the inner wall surfaces of the metal tubes 4, 6, so although side pressure is applied to the metal tubes 4, 6 As long as the metal pipes 4 and 6 are not squashed, the optical fiber core wire 10 will not be damaged. Moreover, if the loop clearance radius r of the metal pipes 4 and 6 is designed to exceed the allowable bending radius of the optical fiber mandrel 10 in advance, the optical fiber core wire 10 will not be damaged or damaged due to excessive bending during the operation of the cable.
