  First, the optical fiber cord 100 to be attached to the retractable display device 10 as the first embodiment according to the present invention will be briefly described. FIG. 1 is a perspective view illustrating a configuration example of the optical fiber cord 100. An optical fiber cord 100 shown in FIG. 1 constitutes an example of an object to be identified, and is used as a wiring for optical communication. The optical fiber cord 100 includes an optical cord 2 and a connector plug 1.

  The optical cord 2 has a relatively thin diameter of about 2 mm, for example, and constitutes an optical signal transmission path. The optical cord 2 is configured, for example, such that an optical fiber core wire having a diameter of 0.9 mm is reinforced with tensile strength fibers and further covered with a plastic resin or the like.

  A connector plug 1 is connected to the end of the optical cord 2. The connector plug 1 includes a ferrule 3, a knob 4, a plug frame 5, and a hood 6. For example, the outer diameter in the short direction is 8.5 mm and the outer diameter in the longitudinal direction is about 55 mm. Yes.

  The ferrule 3 is connected to the end of the optical fiber core wire of the optical cord 2 to constitute an optical signal transmission / reception unit. The ferrule 3 is made of, for example, a stainless steel, and transmits incident light to the subsequent optical cord 2 and transmits light emitted from the optical cord 2 to a subsequent connection destination.

  The ferrule 3 is housed inside the plug frame 5. The plug frame 5 is made of plastic, for example, and protects the ferrule 3 from external force.

  The plug frame 5 is further accommodated inside the knob 4. The knob 4 is made of plastic, for example, and has a groove portion 4a for preventing slippage on the surface, and becomes a portion to be gripped when the connector plug 1 is inserted and removed. The operator inserts and removes the connector plug 1 by pinching the periphery of the groove 4a of the knob 4 with, for example, an index finger and a thumb.

  The optical cord 2 exiting from the knob 4 is covered with a hood 6. The hood 6 is made of, for example, plastic having flexibility, and relaxes bending force and tension applied to the optical cord 2. In this way, the optical fiber cord 100 is configured. A retractable indicator 10 as shown by a broken line is connected to the knob 4 of the optical fiber cord 100.

  FIG. 2 is a perspective view showing a configuration example of the retractable display device 10 according to the present invention. The retractable display 10 shown in FIG. 2 constitutes an example of a display and displays an identification mark of the optical fiber cord 100.

  The retractable display 10 includes a display tag 11, a retractor 12, a case 13, and a mounting band 14. When displaying an identification mark, the display tag 11 is pulled out from the case 13 and the identification mark is displayed. When not displayed, the display tag 11 is stored inside the case 13.

  The display tag 11 constitutes an example of a display tag part, and an identification mark such as a use and a connection destination is described. The display tag 11 includes a bill part 11a and a stopper 11b. The bill portion 11a has a sufficient tensile strength and is formed into a belt shape by a flexible material, for example, a synthetic resin film. A stopper 11b is connected to one end of the bill portion 11a. The stopper 11b is made of a material such as plastic, and is configured in a cylindrical shape having an opening / closing part. The stopper 11 b is connected to the bill portion 11 a by gripping the end portion of the bill portion 11 a and prevents the bill portion 11 a from being completely wound inside the case 13.

  The other end of the bill portion 11 a is connected to the winder 12. The winder 12 constitutes an example of a restoring mechanism unit, and applies a restoring force for winding the display tag 11 into the case 13.

  The winder 12 includes a main shaft 12a, a winding cylinder 12d, a fixing tool 12e, a connecting tool 12b (see FIG. 3), and a torsion coil spring 12c (see FIG. 3).

The main shaft 12a is made of, for example, plastic, and is firmly fixed to the inside of both bottom surfaces of the case 13 by fixtures 12e1 and 12e2 (hereinafter, referred to as the fixture 12e together) connected to both ends.

  The fixing tool 12e is formed in a polygonal thin column shape, for example, with plastic. The fixing tool 12e is fixed to the case 13 by being fitted to, for example, a portion protruding to the inside of both bottom surfaces of the case 13 and a fixing claw 13b (referring to both the fixing claw 13b1 and 13b2) (see FIG. 4).

  One end of a coil spring 12c is connected to the main shaft 12a via a connector 12b (see FIG. 3).

  The torsion coil spring 12 c constitutes an example of an elastic body (spring) that winds the display tag 11 around the case 13. When a tension in a pulling direction is applied to one end, the torsion coil spring 12 c is pulled and the end is pulled out. When released from, it has the property of returning to its original shape. As the coil spring 12c, for example, a metallic coil spring having an inner diameter that can penetrate the main shaft 12a is used.

  The other end of the torsion coil spring 12c is connected to the winding cylinder 12d. The winding cylinder 12d is opened with an opening 12d1 (see FIG. 3) that can penetrate the main shaft 12a on one bottom surface, in FIG. 2, for example, on the bottom surface in FIG. 2, and on the other bottom surface, in FIG. The bottom is formed in a cylindrical container shape with a full opening. The end of the torsion coil spring 12c is firmly connected, for example, through a needle hole on the upper surface of the winding cylinder 12d. By configuring the winder 12 in this way, the winding cylinder 12d rotates reversibly with respect to the main shaft 12a.

  The above-described display tag 11 is connected to the outer surface of the winding cylinder 12d of the winder 12. The take-up cylinder 12d rotates so that the main shaft 12a can be restored, and operates so that the display tag 11 is pulled out when tension is applied to the display tag 11, and the display tag 11 is wound up when released from the tension. .

  The entrainer 12 connected to the display tag 11 is housed in the case 13. The case 13 constitutes an example of a storage unit, and stores the display tag 11 inside by the restoring force of the retractor 12. In this example, the case 13 is formed into a cylindrical container from plastic. In this example, the case 13 includes a lid portion 13c and a cylindrical container portion 13d. On the inner side of the bottom surface of the lid portion 13c and the cylindrical container portion 13d, a fixing claw 13b is formed so as to protrude. The fixing claw 13b is formed so as to have, for example, a hexagonal concave portion in the center portion that matches the size of the fixing tool 12e (see FIG. 4).

  A slit 13 a is opened on the side surface of the case 13. The slit 13a constitutes a take-out port for unwinding or winding the display tag 11, and is opened to a size larger than the width of the above-mentioned tag portion 11a and smaller than the width of the stopper 11b.

  An attachment band 14 is connected to one bottom surface of the case 13. The attachment band 14 constitutes an example of an attachment portion, and attaches the case 13 to the optical fiber cord 100. The attachment band 14 is made of, for example, a plastic having a restoring force, and holds the connector plug 1 of the optical fiber cord 100 shown in FIG.

  The attachment band 14 is opened so that the opening 14a is opened and, for example, a portion having a relatively high contact resistance such as the groove 4a shown in FIG. Attach to 1. In this way, the retractable display tool 10 is configured. Hereinafter, a method for manufacturing (assembling) the retractable display device 10 will be described with reference to FIGS.

  3A to 3D are cross-sectional views illustrating an assembly example (part 1) of the retractable display tool 10. FIG. Here, a method for assembling the winder 12 according to the roll-in display device 10 will be described. When assembling the winder 12, first, a fixture 12e1 shown in FIG. 3A is prepared.

  The fixture 12 e 1 is for connecting the main shaft 12 a to the upper surface of the case 13. Therefore, for example, it may be formed in a polygonal shape such as a hexagon. When the fixture 12e1 is manufactured, for example, a mold having a hexagonal column-shaped recess with a circumscribed circle having a diameter of about 5 to 8 mm is prepared, and a plastic resin is poured into a height of about 1 to 3 mm and solidified. A cylindrical recess 12e11 into which the main shaft 12a is fitted is opened on one surface of the formed fixture 12e.

  Next, a winding cylinder 12d shown in FIG. 3B is prepared. The winding cylinder 12d is formed in a cylindrical container having an opening 12d1 that can penetrate the main shaft 12a in the upper bottom surface and an opening in the entire bottom surface. When manufacturing the winding cylinder 12d, for example, a cylindrical mold having a diameter of 4 to 7 mm smaller than the recess is floated on a mold having a cylindrical recess having a diameter of 6 to 8 mm, and the bottom surface is floated by about 1 to 2 mm. For example, a plastic resin is poured into a mold fixed in a heated state to a height of 4 to 5 mm and hardened. Further, at this time, it is preferable to form a convex portion in advance of the opening 12d1 on the bottom surface of the inner cylindrical mold.

  Next, the part shown in FIG. 3C to be stored in the winding cylinder 12d is assembled. The part shown in FIG. 3C is formed by assembling the main shaft 12a, the coupling tool 12b, the torsion coil spring 12c, and the fixing tool 12e2. In order to assemble these, first, the main shaft 12a is prepared.

  The main shaft 12a is formed in a rod shape having a minimum size capable of ensuring strength, for example, a diameter of about 3 to 4 mm and a height of about 5 to 6 mm, for example, of plastic. When the main shaft 12a is manufactured, it is preferable to form the main shaft 12a by pouring a plastic resin into a mold having a cylindrical recess.

  A fixture 12e2 is connected to the bottom surface of the main shaft 12a. The fixture 12e2 is formed in the same column shape as the fixture 12e1 shown in FIG. 3A. The main shaft 12a is fitted into a recess 12e21 formed in the fixture 12e2, and is firmly connected, for example, with a strong adhesive. In addition, the fixture 12e2 may be formed in advance by being integrated with the main shaft 12a.

  A torsion coil spring 12c is engaged with the main shaft 12a so as to penetrate the main shaft 12a. One end of the engaged torsion coil spring 12c is coupled to the main shaft 12a via the coupling tool 12b. The other end of the torsion coil spring 12c is firmly connected to the winding cylinder 12d.

  The connector 12b may be formed by pouring plastic resin or rubber resin into a predetermined mold. For example, the connector 12b is formed in a donut shape in which a hole that can penetrate the main shaft 12a is opened at the center. When the connector 12b is manufactured, after the liquefied material is poured into a mold having a cylindrical recess and solidified, a cylindrical hole that penetrates the main shaft 12a is opened at the center by a drill or the like. It is good to form.

  The connector 12b is connected to the main shaft 12a with a strong adhesive or the like through the main shaft 12a through the opened hole in the center. Further, the connecting tool 12b may be previously integrated with the main shaft 12a.

  3C is assembled in this way, the winder 12 shown in FIG. 3D is assembled. When assembling the winder 12 shown in FIG. 3D, first, the part of FIG. 3C is inserted from the bottom surface of the winding cylinder 12d, and the torsion coil spring 12c is connected. A needle hole for connecting the torsion coil spring 12c is opened at a predetermined portion on the upper surface of the winding cylinder 12d, and one end of the torsion coil spring 12c is bent after being inserted into the needle hole. It is firmly connected to the cylinder 12d.

  Next, the upper end portion of the main shaft 12a is taken out from the opening 12d1 of the winding cylinder 12d, and is fitted into the recess 12e11 of the fixture 12e1 shown in FIG. 3A, and is fixed with a strong adhesive or the like. In this way, the winder 12 can be assembled.

  As shown by the broken line in FIG. 3D, the bill portion 11a is connected to the winding cylinder 12d of the assembled winder 12. The bill portion 11a is formed by cutting a synthetic resin film into a strip shape having a width of about 3.5 mm and a length of about 50 mm to 100 mm in this example. In order to connect the bill portion 11a to the winding tube 12d, one end of the bill portion 11a is attached to the surface of the winding tube 12d with, for example, a strong adhesive. At this stage, the stopper 11b is not connected to the other end of the bill portion 11a.

  Thus, the site | part which concerns on the winding device 12 can be assembled. Next, a description will be given of a method for assembling a portion related to the winder 12 into the case 13 and assembling it into a shape attached to the optical fiber cord.

4A to 4D are cross-sectional views showing an assembly example (No. 2) of the retractable display tool 10. Here, in order to store the portion related to the winder 12 assembled as described above in the case 13, first, the lid portion 13c shown in FIG. 4A is prepared.

  In this example, the lid portion 13c is formed in a disk shape with the fixed claw 13b1 protruding. When manufacturing the lid part 13c, for example, a mold having a cylindrical recess having a diameter of 12 mm is prepared. On the bottom surface of the cylindrical concave portion, a concave portion that further imitates the fixing claw 13b1 is formed. A plastic resin is poured into this mold to a height of, for example, 1 to 2 mm and hardened to form the lid portion 13c.

  4B, the fixing device 12e1 on the upper surface is fitted into the fixing claw 13b1 of the lid portion 13c and fixed. Further, the lower surface fixing tool 12e2 is fitted into the fixing claw 13b2 of the cylindrical container portion 13d.

  The cylindrical container portion 13d in FIG. 4C is formed in a shape having the same size as the lid portion 13c, for example, a circular bottom surface having a diameter of 12 mm and a side surface having a height of 6 mm. When manufacturing the cylindrical container part 13d, for example, a cylindrical concave part having a diameter of 12 mm is fixed to a mold with a cylindrical part having a diameter smaller than the concave part, for example, 10 mm in diameter, with the bottom surface being floated by 1 to 2 mm. Prepare the mold. At this time, a recess that is shaped like the fixing claw 13b2 is formed on the bottom surface of the inner cylindrical mold. The cylindrical container portion 13d is formed by pouring, for example, plastic resin into the mold and hardening.

  A slit 13a is opened on the side surface of the cylindrical container portion 13d that is taken out from the mold. The slit 13a is opened by an electric cutter or the like in the form of an elongated slit having a width slightly larger than the thickness of the display tag 11.

  The attachment band 14 shown in FIG. 4D connected to the bottom surface of the cylindrical container portion 13d is formed by bending a belt-like plastic having a strong restoring force, for example. In this example, the attachment band 14 is formed so as to have the opening 14a at the time of attachment. However, the attachment band 14 is not limited thereto, and may be shaped so that both ends are connected at the time of attachment. Alternatively, it may be formed in a ring shape with a stretchable material such as rubber and attached to the knob 4. Alternatively, the attachment band 14 may be formed with a strong tape and directly attached to the knob 4.

  FIG. 5 is a cross-sectional view showing an assembly example (part 3) of the retractable display 10. When assembling the retractable display tool 10 shown in FIG. 5, first, the part related to the winder 12 shown in FIG. 4B is put in the cylindrical container part 13d, and the fixing tool 12e2 on the bottom is fixed to the fixing claw of the cylindrical container part 13d. Fit into 13b2. At this time, it may be more strongly connected with a strong adhesive or the like.

  After the connection, the one end of the bill portion 11a that has been released is pulled out from the slit 13a, and the stopper 11b is connected to the pulled-out end. At this time, in a normal state where no tension can be applied from the outside, it may be adjusted so that a slight restoring force is applied to the bill portion 11a and the stopper 11b is attracted to the slit 13a.

  Next, the cover part 13c is covered from the upper part of the cylindrical container part 13d and connected with, for example, an adhesive, and the case 13 is sealed. At this time, the fixing claw 13b1 of the lid portion 13c is fitted and fixed to the fixture 12e1 on the upper surface of the winder 12.

  Finally, the attachment band 14 is connected to the bottom surface of the case 13 with a strong adhesive, for example. The retractable display tool 10 can be assembled as described above.

  FIG. 6 is a perspective view showing an attachment example of the retractable display 10. A retractable display 10 shown in FIG. 6 is attached to an optical fiber cord 100 connected to the optical connection unit 102. When the retractable display device 10 is attached, if the stopper 11b of the display tag 11 is in a direction transverse to the insertion direction of the optical fiber cord 100, the display tag 11 can be easily pulled out in the direction of the optical cord 2 (broken line). L1 direction). In this example, the winding direction of the display tag 11 is preferably set to the direction indicated by the broken line L2.

  FIG. 7 is a perspective view showing a handling example of the retractable display 10. The retractable display 10 shown in FIG. 7 shows a state where the display tag 11 is pulled out from the case 13. In this way, when displaying the identification mark, the display tag 11 is pulled out of the case 13 while holding the stopper 11b. When the identification mark is not displayed, the display tag 11 is wound inside the case 13 by the restoring force of the winder 12 by releasing the stopper 11b. The retractable display 10 in the normal state in which the display tag 11 is wound returns to the state shown in FIG.

  As described above, according to the retractable display 10 according to the first embodiment, the display tag 11 on which the identification mark is displayed is stored in the case 13 by the restoring force of the connected retractor 12. It is. Thereby, when displaying an identification mark, the display tag 11 is pulled out from the case 13, and when not displaying, the display tag 11 is stored inside the case 13.

  Therefore, the display tag 11 can be prevented from getting in the normal time when the identification mark is not displayed, so that it is possible to avoid the troublesomeness caused by the display tool when the object is placed in a narrow place. When this is applied to the connector plug 1 of the optical fiber cord 100 connected to the optical wiring board, it is possible to prevent misidentification of the optical cord 2 to be inserted and removed, and to improve the efficiency in the wiring change work. Further, since only necessary display tags 11 can be pulled out for confirmation, misidentification with other display tags 11 can be prevented.

  In this example, the torsion coil spring 12c is used as the winding spring. However, the present invention is not limited to this, and a spiral spring wound in a spiral shape may be used. When connecting the spiral spring to the winder 12 shown in FIG. 3, the inner end of the spiral spring is connected to the side surface of the main shaft 12a with, for example, a strong adhesive, and the outer end of the spiral spring is It is preferable to firmly connect the inner surface of the winding cylinder 12d. By using the spiral spring in this way, the retractable display device 10 can be thinned.

  Further, as the elastic body for winding, a material such as rubber may be used instead of the spring. By using rubber, weight reduction and cost reduction can be realized.

  Further, a fixing mechanism that can stop the rotation of the winding cylinder 12 d may be formed in the winder 12 so that the fixing mechanism can be operated by an operating means such as a button on the side surface of the case 13. With this configuration, the display tag 11 can be fixed in the pulled-out state, so that the wiring work can be performed while referring to the plurality of display tags 11 necessary for the work.

  FIG. 8 is a perspective view showing a configuration example of a retractable display 20 as a second embodiment according to the present invention. The retractable display tool 20 shown in FIG. 8 constitutes an example of a display tool and is attached to the knob 4 of the optical fiber cord 100.

  The retractable display 20 includes a display tag 21, a retractor 22, a case 23, and a mounting band 24. When displaying an identification sign, the display tag 21 is pulled out from the case 23 and does not display the identification sign. In this case, the display tag 21 is stored inside the case 23.

  The display tag 21 constitutes an example of a display tag unit, and is labeled with an identification mark such as a use or a connection destination. The display tag 21 includes a bill portion 21a and a stopper 21b. The bill portion 21a has a sufficient tensile strength and is formed in a band shape from a flexible material such as a synthetic resin film.

  A stopper 21b is connected to one end of the bill portion 21a. The stopper 21b is made of a material such as plastic and has a cylindrical shape having an opening / closing portion, for example, and is connected to the bill portion 21a by grasping an end portion of the bill portion 21a, so that the bill portion 21a is completely attached to the case 23. Prevents being drawn inside. A hole 21a1 is opened at the other end of the bill portion 21a.

  A retractor 22 is connected to the bill portion 21a. The retractor 22 constitutes an example of a restoration mechanism unit, and applies a restoring force for pulling the display tag 21 into the case 23.

  The retractor 22 includes a coil spring 22c and a connector 22b. The connector 22b is configured to grip and reinforce the end portion of the bill portion 21a. The connector 22b is formed like a strong metal clip, for example, and grips and fixes the end of the bill portion 21a. A hole 22b1 is opened in the connector 22b at a position overlapping the hole 21a1 of the gripped tag 21a. One end of the coil spring 22c is inserted into the hole 21a1 and the hole 22b1, and then bent and connected.

  The coil spring 22c constitutes an example of a spring that pulls the display tag 21 into the case 23. When a tension in a pulling direction is applied to one end, the coil spring 22c extends and the end is pulled out. It has the property of returning to shape. For example, a metallic coil spring is used for the coil spring 22c.

  The other end of the coil spring 22c is housed in the case 23 and fixed. The case 23 constitutes an example of a storage unit, and stores the display tag 21 inside by the restoring force of the retractor 22. In this example, the case 23 is formed in a substantially cylindrical container having a length capable of accommodating the display tag 21 by plastic. The portion of the case 23 from the insertion portion 23a to the position where the coil spring 22c is accommodated is formed in a cylindrical shape, but is formed in a shape that is flattened around the attachment portion 23b to the attachment band 24. The

  A hole 23c for fixing the coil spring 22c is opened in the mounting portion 23b. One end of the coil spring 22c housed in the case 23 is fixed by a fixing pin 27 inserted from the hole 23c.

  An attachment band 24 is coupled to the attachment portion 23 b of the case 23. The attachment band 24 constitutes an example of an attachment portion, and attaches the case 23 to the optical fiber cord 100. The attachment band 24 is made of plastic, for example, and is configured to hold the connector plug 1 of the optical fiber cord 100. In this way, the retractable display tool 20 is configured. Hereinafter, a (manufacturing) assembly method of the retractable display 20 will be described.

  FIG. 9 is a perspective view showing an assembly example of the retractable display tool 20. When the retractable display device 20 is manufactured (assembled) as shown in FIG. 9, first, the display tag 21 is prepared.

  The tag portion 21a of the display tag 21 is formed, for example, by cutting a synthetic resin film into a strip shape having a width of 3.5 mm and a length of about 50 mm to 100 mm. A stopper 21b is connected to one end of the bill portion 21a. The stopper 21b is formed in a size or shape that does not enter the insertion portion 23a of the case 23, for example, of plastic. A hole 21a1 for connecting the coil spring 22c is opened at the other end of the bill portion 21a. A connector 22b is connected to the end of the display tag 21 where the hole 21a1 is opened.

  The connector 22b is formed in a shape that can be opened and closed by metal, for example. A biting claw is preferably formed at the joint when the connector 22b is opened and closed so that the tag portion 21a can be securely gripped. Alternatively, the joint surface may be connected with a strong adhesive when the tag portion 21a is gripped by the connecting tool 22b. A hole 22b1 is opened in the connector 22b at a position overlapping the hole 21a1. One end of the coil spring 22c is inserted into the hole 22b1.

  For example, a metal coil spring is used as the coil spring 22c. As the coil spring 22c, a spring having sufficient stretchability and restoring force is used. The other end of the coil spring 22 c is connected to the mounting portion 23 b of the case 23.

  The case 23 is formed in a substantially cylindrical shape by, for example, plastic. When manufacturing the case 23, a plastic tube having an appropriate hardness, for example, an inner diameter of 4 to 5 mm, is cut into a length in which the display tag 21 and the coil spring 22c can be accommodated, for example, 60 to 110 mm. The hole 23c is opened through two opposing surfaces.

  In order to connect the end of the coil spring 22c to the mounting portion 23b of the case 23, the fixing pin 27 is inserted through the opened hole 23c, and the coil spring 22c is fixed inside the case 23 so as to be hooked. The fixing pin 27 may be taken out of the case 23 from the hole 23c on the opposite surface of 23, and the end portion may be bent. By doing so, the end of the coil spring 22c can be fixed, and the shape of the mounting portion 23b can be formed.

  The attachment band 24 is connected to the formed attachment portion 23b by a strong adhesive. Alternatively, a hole may be opened in the attachment band 24 and a fixing pin 27 may be inserted to fix the attachment portion 23 b and the attachment band 24. In this way, the case 23 and the attachment band 24 can be more firmly connected. In this manner, the retractable display tool 20 can be assembled.

  When the assembled retractable display 20 displays an identification mark as shown by the two-dot chain line in FIG. 8, the display tag 21 is pulled out of the case 23 while holding the stopper 21b. When the identification mark is not displayed, the display tag 21 is pulled into the case 23 by the restoring force of the retractor 22 by releasing the stopper 21b. The retractable display 20 in the normal state where the display tag 21 has been pulled back returns to the state shown by the solid line in FIG.

  Thus, according to the retractable display device 20 according to the second embodiment, the display tag 21 on which the identification mark is displayed is stored in the case 23 by the restoring force of the retractor 22 to be connected. is there.

  Accordingly, the display tag 21 can be prevented from getting in the normal time when the identification mark is not displayed, so that it is possible to avoid the trouble caused by the display tool that occurs when the connector plug 1 is arranged in a narrow place. Further, since the case 23 is arranged along the connector plug 1, an increase in thickness when the connector plug 1 is attached can be minimized.
