Description

  The present invention relates to a binding tool that binds at least a part of a linear member wound in an annular shape.

  It is known as a prior art to bind an annular portion of a linear member such as an optical fiber core wire, at least a part of which is wound in an annular shape.

  As a binding tool for binding the annular portion of such a linear member, for example, there is one shown in Patent Document 1. This binding tool is fitted with a cylindrical condensing body having a round hole-shaped storage portion for holding a linear member and having a flexibility that can be elastically deformed in a radial direction, and an outer peripheral surface of the converging body. And an elastically deformable annular fastening body for fastening the storage portion. The converging body is formed with a split portion that communicates the outer peripheral surface of the converging body with the storage portion and guides the linear member to the storage portion. The fastening body has a cutout portion through which the linear member can pass.

  And in the thing of patent document 1, if a linear member is guide | induced from a cutting part and it accommodates in a storage part, according to the number of a linear member and the magnitude | size of a diameter, the shape of a focusing body and a storage part will change. Thus, the linear member is bundled in the storage portion. On the other hand, when the linear member is passed through the cutout portion and the fastening body is fitted to the converging body so that the cutout portion and the cutout portion are not in the same direction, the storage portion is tightened so that the linear member is tightened. In addition, the linear member in the storage portion does not come out of the cut portion. Further, when a bending stress acts on the linear member, the converging body bends so that the linear member does not bend according to the stress.

  However, in the thing of patent document 1, when binding a linear member, while guiding a linear member from the split part of a focusing body and storing in a storage part, it is necessary to fit a fastening body to a focusing body. , It took time.

  The present invention has been made in view of such a point, and an object of the present invention is to provide a binding tool that binds the annular portion of a linear member wound at least partially in an annular shape. It is to reduce the work time when binding the parts.

  1st invention is a binding tool which binds this cyclic | annular part in the linear member in which at least one part was cyclically | annularly wound, Comprising: The sheet-like member which has flexibility is provided in the said sheet-like member. The first and second holes are spaced apart from each other, and a cut is formed between the first and second holes so that the first and second holes are connected to each other. The annular part is inserted into the first and second holes through the cut, and is configured to bind the annular part of the linear member in a state where the sheet-like member is bent. It is characterized by.

  According to this, the first and second holes are formed in the sheet-like member having flexibility so as to be spaced apart from each other, and the first and second holes are connected to each other between the first and second holes. Are formed, and the annular portion of the linear member is bound in a state where the sheet-like member is bent, by inserting the annular portion of the linear member through the first and second holes through the cut line. In this way, to bind the annular portion of the linear member, it is only necessary to insert the annular portion of the linear member through the first and second holes through the cut line. It is possible to shorten the work time when doing.

  According to a second invention, in the first invention, the cut is formed so as to protrude to one side in a direction orthogonal to the linear direction with respect to a straight line connecting the first and second holes. It has one protrusion part, It is characterized by the above-mentioned.

  According to this, the cut has at least one projecting portion formed so as to project to one side in a direction orthogonal to the linear direction with respect to a straight line connecting the first and second holes. And the protrusion part part of a cut | interruption can be opened largely. For this reason, when the annular portion of the linear member is inserted into the first and second holes through the cut, the annular portion of the linear member can be easily passed through the cut, and the annular portion of the linear member is bound. It is possible to further reduce the working time when doing so.

  According to a third aspect, in the second aspect, in addition to the protrusion, the cut is a linear first formed so as to extend in the linear direction between the first hole and the protrusion. It further has a linear portion and a linear second linear portion formed so as to extend in the linear direction between the second hole and the protruding portion.

  According to this, in addition to the projecting portion, the cut line includes a linear first straight portion formed so as to extend in a linear direction connecting the first and second holes between the first hole and the projecting portion. And a linear second linear portion formed so as to extend in a linear direction between the second hole and the protruding portion. And the 1st and 2nd linear part part of a cut cannot be opened largely. For this reason, after bundling the annular part of the linear member, the binding tool falls off from the annular part of the linear member (that is, the annular part of the linear member comes off from the first and second holes through the cut). Can be suppressed.

  A fourth invention is characterized in that, in the second or third invention, the protrusion is V-shaped.

  According to this, since the projecting portion is V-shaped, the projecting portion of the cut can be easily formed.

  According to a fifth invention, in any one of the first to fourth inventions, the sheet-like member is formed by laminating paper.

  According to this, since the sheet-like member is formed by laminating paper, the first and second holes and cuts can be easily formed, and by laminating, the sheet-like member can be formed. The strength and waterproofness can be improved.

  According to the present invention, the first and second holes are formed in the flexible sheet-like member so as to be spaced apart from each other, and the first and second holes are connected to each other between the first and second holes. Each cut is formed, and the annular portion of the linear member is bound in a state where the sheet-like member is bent by inserting the annular portion of the linear member through the first and second holes through the cut. Thus, the bundling of the annular portion of the linear member only requires the operation of inserting the annular portion of the linear member through the first and second holes through the cut line, The work time for binding the parts can be shortened.

(Embodiment 1)
FIG. 1 is a plan view of a fiber clip according to an embodiment of the present invention, and FIG. 2 is a plan view showing a state in which optical fiber cores wound in a substantially annular shape are bundled with a fiber clip. The clip 2 (binding tool) is a flexible and elastic medical optical fiber core wire 11 (linear member) in which at least a part (a part other than both ends in FIG. 2) is wound in a substantially annular shape. By bundling the annular portion 11a, the bundle shape is maintained, and the end of the optical fiber core wire 11 (hereinafter, the end of the optical fiber core wire 11 is also referred to as “protected portion”) When processing the end of the optical fiber core 11 such as removing the outer sheath at the end of the optical fiber core 11, carrying the optical fiber core 11, shipping the optical fiber core 11, etc. Used. At least one fiber clip 2 is attached to the optical fiber core wire 11 in order to bind at least one annular portion 11a of the optical fiber core wire 11. In FIG. 2, for example, the annular portion of the optical fiber core wire 11 is attached. Two are attached to the optical fiber core wire 11 in order to bind the 11a at two places. The annular portion 11a of the optical fiber core wire 11 is wound more than double, and in FIG. 2, for example, it is wound four times. In FIG. 2, the portions other than both ends of the optical fiber core wire 11 are wound in a substantially annular shape. However, the present invention is not limited to this. For example, the optical fiber core wire 11 is transported, shipped, and packed. You may wind substantially all the core wires 11 in a substantially annular shape.

  The fiber clip 2 is composed of a sheet-like member 12 having flexibility and elasticity obtained by laminating (pouching) paper. Lamination is performed as follows, for example. In other words, the paper (sheet) is sandwiched with a laminate sheet made by applying an adhesive to a resin sheet such as PET (polyethylene terephthalate) or PE (polyethylene), and heat or pressure is applied. Do by covering. The laminate sheet and the adhesive are desirably transparent. By doing so, the information described and displayed on the paper can be visually recognized and can be protected. The laminate sheet may be a single layer or may be laminated.

  The sheet-like member 12 has an octagonal shape in which the four corners of the rectangular sheet-like member are each cut into a triangular shape. The longitudinal length (horizontal) of the sheet-like member 12 is, for example, 44 mm, the lateral length (vertical) is, for example, 17 mm, and the thickness thereof is, for example, 300 μm to 600 μm. If the thickness is 400 μm to 600 μm, This is preferable because the holding force of the linear member and the durability of the sheet-like member 12 itself are improved. The sheet-like member 12 is in a horizontal state when not attached to the optical fiber core wire 11. The sheet-like member 12 is formed, for example, by cutting a drawing sheet in which a laminate film (pouch film) is laminated and bonded on each side with a cutter. In the following description, the longitudinal direction of the sheet-like member 12 is the left-right direction, and the short direction is the up-down direction. Further, the surface of the sheet-like member 12 that is visible in FIG. 1 is the front surface, and the surface that is not visible is the back surface.

  The sheet-like member 12 has circular first and second holes 22 and 32 spaced apart from each other by a predetermined distance in the left-right direction, and the first and second holes 22 between the first and second holes 22 and 32. , 32 are formed so as to penetrate each other so as to penetrate each other. That is, the first hole 22, the cut line 42, and the second hole 32 are continuous in the left-right direction. The first hole 22 is formed in the vertical center of the left end portion of the sheet-like member 12, and the second hole 32 is formed in the vertical center of the right end portion of the sheet-like member 12. The diameters of the first and second holes 22 and 32 have the same length that allows the annular portion 11a of the optical fiber core wire 11 to be inserted, for example, 5 mm. The distance from the center of the first hole 22 to the center of the second hole 32 (that is, the predetermined interval) is, for example, 29 mm. The first and second holes 22 and 32 are punched, for example, with a punch.

  The cut 42 is non-linear. Specifically, the cut line 42 has a lower side (that is, a direction orthogonal to the direction in which the straight line L extends) with respect to a straight line L (shown only in FIG. 1) connecting the centers of the first and second holes 22 and 32. One V-shaped projecting portion 42a formed so as to project to one side, and extends in the left-right direction (straight line L direction) between the first hole 22 and the projecting portion 42a, and projects from the first hole 22 The first linear portion 42b formed in a straight line so as to be connected to the portion 42a, and extends in the left-right direction between the second hole 32 and the protruding portion 42a, and the second hole 32 and the protruding portion 42 are connected to each other. And a straight second straight portion 42c formed as described above. The protruding portion 42a has a horizontal length of, for example, 14 mm, and a vertical length of, for example, 5 mm. The first and second straight portions 42b and 42c extend from the center in the vertical direction of the first and second holes 22 and 32 to the inside in the left and right direction so as to overlap the straight line L, respectively. The left and right lengths of the first and second straight portions 42b and 42c are the same as each other, and are shorter than the left and right length of the protruding portion 42a. The cut 42 is cut with a cutter, for example.

  It should be noted that the surface of the sheet-like member 12 may be configured to be able to describe / display information on the linear members to be bound, work records, and the like.

-Detaching method of fiber clip to optical fiber core wire-
Hereinafter, a method for attaching and detaching the fiber clip 2 to the optical fiber core wire 11 will be described with reference to FIGS.

  First, an example of a method for attaching the fiber clip 2 to the optical fiber core wire 11 will be described. First, in a state in which the upper part of the cut 42 in the sheet-like member 12 is held, the lower part of the cut 42 in the sheet-like member 12 is bent to the back surface side with respect to the upper part of the cut 42, thereby making the cut 42 Open. And as shown in FIG. 3, the cyclic | annular part 11a of the optical fiber core wire 11 is pinched | interposed into the open cut 42. As shown in FIG. Then, as shown in FIGS. 4 and 5, the lower portions of the first and second straight portions 42 b and 42 c in the sheet-like member 12 are pushed up in order from the back side. Then, the annular portion 11a of the optical fiber core wire 11 is positioned between the first and second holes 22 and 32 on the outer surface of the sheet-like member 12 outside the first and second holes 22 and 32 in the left-right direction. In addition, the sheet-like member 12 is elastically deformed and the left and right direction is inserted into the first and second holes 22 and 32 in a state of passing through the back side thereof in the left and right directions of the second holes 22 and 32. It bends so that the center part protrudes to the surface side rather than both ends. In this way, the fiber clip 2 is attached to the annular portion 11 a of the optical fiber core wire 11, and the annular portion 11 a of the optical fiber core wire 11 is bound by the fiber clip 2.

  By the way, when the fiber clip 2 is attached to the optical fiber core wire 11, the sheet-like member 12 is bent as described above, so that it tries to return to the original horizontal state. Further, of the bundle of the annular portions 11 a of the optical fiber core wire 11 bound by the fiber clip 2, the end portion of the optical fiber core wire 11 (that is, the fiber clip 2 and the optical fiber core wire 11 of the optical fiber core wire 11). One continuous line portion (hereinafter also referred to as a straight portion 11b) between the ends spreads outward in the first and second holes 22 and 32 in order to return to the original straight shape. I will try. One of the bundles of the elastic force (restoring force) for the sheet-like member 12 to return to the horizontal state and the annular portion 11a of the optical fiber core wire 11 spreads outward in the first and second holes 22 and 32. The bundling position of the optical fiber core wire 11 by the fiber clip 2 is held at an arbitrary position by the elastic force to be peeled off.

  Further, when the fiber clip 2 is attached to the optical fiber core wire 11, as described above, the annular portion 11 a of the optical fiber core wire 11 is inserted into the first and second holes 22 and 32, so that the sheet-like member 12 is guided by the annular portion 11a of the optical fiber core 11 and is slidable along the annular portion 11a (see the two-dot chain line in FIG. 2). By the sliding movement of the sheet-like member 12, the binding position of the optical fiber core wire 11 by the fiber clip 2 is changed. And if the binding position of the optical fiber core wire 11 by the fiber clip 2 is changed, the length of the linear part 11b of the optical fiber core wire 11 will be changed.

  Next, an example of a method for removing the fiber clip 2 from the optical fiber core wire 11 will be described. First, as shown in FIG. 6, the lower portion of the cut 42 in the sheet-like member 12 is bent toward the back surface side with respect to the upper portion of the cut 42 to open the cut 42. Then, as shown in FIG. 7, the annular portion 11 a of the optical fiber core wire 11 exits through the open cut 42. Thus, the fiber clip 2 is removed from the annular portion 11a of the optical fiber core wire 11.

  As described above, the fiber clip 2 can be detached from the optical fiber core wire 11 with one touch.

  By the way, in general, the annular portion 11a of the optical fiber core wire 11 is bundled by winding the annular portion 11a of the optical fiber core wire 11 with a vinyl tie or a string, or fixing it with a spiral tube or tape. Are known.

  However, when the annular portion 11a of the optical fiber core wire 11 is bundled with a vinyl tie or the like, the operation takes time. Similarly, when removing a vinyl tie etc. from the optical fiber core wire 11, it takes time for the work. When the end of the optical fiber core 11 is processed, in order to improve the workability, the end of the optical fiber core 11 is usually made straight. For this reason, it is necessary to once remove the vinyl tie near the end of the optical fiber core wire 11 from the optical fiber core wire 11, but after the end processing of the optical fiber core wire 11, the annular portion of the optical fiber core wire 11 is removed. 11a has to be rebound with a vinyl tie or the like, and eventually the work takes time. In this way, after removing the vinyl tie or the like from the optical fiber core 11 once, when the annular portion 11a of the optical fiber core wire 11 is rebound with the vinyl tie or the like, the optical fiber core wire 11 is rubbed at that time, There is also a possibility that the optical fiber core wire 11 may be damaged. Further, when the annular portion 11 a of the optical fiber core wire 11 is fixed with a tape, the adhesive may adhere to the optical fiber core wire 11.

  Here, according to the present embodiment, as described above, the fiber clip 2 can be attached to and detached from the optical fiber core 11 with a single touch. It takes less time for the terminal processing of the core wire 11. Moreover, since the length of the linear part 11b of the optical fiber core wire 11 can be changed by changing the binding position of the optical fiber core wire 11 by the fiber clip 2 as described above, There is no need to remove the fiber clip 2 from the optical fiber core 11 when the end of the core wire 11 is processed. For this reason, it can suppress that the optical fiber core wire 11 is damaged. Furthermore, there is no possibility that the adhesive will adhere to the optical fiber core wire 11.

-Effect-
As described above, according to the present embodiment, the flexible sheet-like member 12 is provided with the first and second holes 22 and 32 between the first and second holes 22 and 32 so as to be spaced apart from each other. The cut 42 is formed so that the first and second holes 22 and 32 are connected to each other, and the annular portion 11a of the optical fiber core wire 11 is inserted into the first and second holes 22 and 32 through the cut 42. By doing so, the annular portion 11a of the optical fiber core wire 11 is bound in a state where the sheet-like member 12 is bent. Thus, to bind the annular portion 11 a of the optical fiber core wire 11, it is only necessary to insert the annular portion 11 a of the optical fiber core wire 11 into the first and second holes 22 and 32 through the cuts 42. Therefore, the working time when bundling the annular portion 11a of the optical fiber core wire 11 can be shortened.

  Further, the cut 42 has one projecting portion 42 a that projects to one side in a direction orthogonal to the direction of the straight line L with respect to the straight line L connecting the first and second holes 22 and 32. And the protrusion part 42a part of the cut | interruption 42 can be opened largely. For this reason, when the annular portion 11a of the optical fiber core wire 11 is inserted into the first and second holes 22 and 32 through the cut 42, the annular portion 11a of the optical fiber core wire 11 is simply passed through the cut 42. Thus, the working time for binding the annular portion 11a of the optical fiber core wire 11 can be further reduced.

  In addition to the protrusion 42a, the cut 42 is a straight line formed so as to extend in the direction of the straight line L connecting the first and second holes 22 and 32 between the first hole 22 and the protrusion 42a. It further has a first straight portion 42b and a straight second straight portion 42c formed so as to extend in the direction of the straight line L between the second hole 32 and the protruding portion 42a. And the 1st and 2nd linear part 42b, 42c part of the cut | interruption 42 cannot be opened largely. For this reason, after bundling the annular portion 11a of the optical fiber core wire 11, the fiber clip 2 falls off from the annular portion 11a of the optical fiber core wire 11 (that is, the annular portion 11a of the optical fiber core wire 11 forms a cut 42). Through the first and second holes 22 and 32).

  Moreover, since the protrusion part 42a is made into the V-shaped thing, the protrusion part 42a part of the cut | interruption 42 can be formed easily.

  Further, since the sheet-like member 12 is formed by laminating paper, the first and second holes 22 and 32 and the cut line 42 can be easily formed, and by laminating, the sheet can be formed. The strength and waterproofness of the shaped member 12 can be improved.

(Embodiment 2)
In the present embodiment, a terminal protector is used in order to further suppress the occurrence of defects in the optical fiber core wire 11 while maintaining the working efficiency of terminal processing by using the fiber clip 2.

  More specifically, the end of the optical fiber core wire 11 may be damaged by an operator's hand or the like hitting the end. In order to suppress such damage to the end portion, the end protector 1 constituting one end processing unit together with the fiber clip 2 is attached to the end portion of the optical fiber core wire 11 bundled with the fiber clip 2. It has been.

  Thus, when the terminal protector 1 is attached to both ends of the optical fiber core wire 11, that is, when the fiber clip 2 and the terminal protectors 1, 1 are used as a terminal processing unit, the end processing is performed. As will be described later, the terminal protector 1 is slid to the opposite side of the tip of the optical fiber core 11 and retracted, and one end of the optical fiber core 11 is polished or inspected. Then, when each step is completed, the terminal protector 1 is slid to the distal end side of the optical fiber core wire 11.

  Hereinafter, the difference from the first embodiment, that is, the terminal protector 1 will be described.

  8 is a side view of a terminal protector for an optical fiber core, FIG. 9 is a cross-sectional view taken along line IX-IX in FIG. 8, and FIG. 12 is a terminal protector for an optical fiber core. It is a figure explaining the attachment state of. This terminal protector 1 is for protecting the end part (one end part) 11e of the optical fiber core wire 11. FIG. In the present embodiment, the protected portion 31 of the optical fiber core wire 11 means a portion obtained by adding a margin length (about 5 mm) to the polished end (processed portion) or the planned processing portion.

  The terminal protector 1 protects a stopper (fixing member) 33 in which a hole 33a through which the optical fiber core wire 11 can be inserted is formed, and a protected portion 31 of the optical fiber core wire 11 that is attached to the stopper 33. A protective tube (protective member) 57 is provided, and the stopper 33 and the protective tube 57 are formed separately.

  The stopper 33 is made of polyvinyl chloride (PVC), and is formed so that the outer diameter increases from one end where the hole 33a is formed toward the other end, as shown in FIG. Specifically, the stopper 33 has a top portion 33b in which a hole 33a is formed and a body portion 33c having an outer diameter larger than that of the top portion 33b, and has a substantially weight shape as a whole.

  The hole 33a only needs to be able to pass through the optical fiber core wire 11. The inner diameter of the hole portion 33a is not particularly defined unless it is extremely small or large with respect to the outer diameter of the optical fiber core wire 11. That is, the hole diameter of the hole 33a may be slightly larger than the outer diameter of the optical fiber core wire 11, or may be slightly smaller. For example, if the hole diameter of the hole 33a is substantially equal to the outer diameter of the optical fiber core wire 11, the stopper 33 is made of an elastic material (made of PVC). While the peripheral wall of the optical fiber slides in the fiber axial direction while elastically contacting the optical fiber core 11b, if no force is applied in the fiber axial direction, the peripheral wall of the hole 33a and the optical fiber core The effect of stopping at a desired position on the optical fiber core wire 11 is obtained by friction with the optical fiber 11b.

  The protective tube 57 is a transparent resin molded product made of polyethylene terephthalate used for a laminate film or the like, and is formed in a cylindrical shape. This protective tube 57 has a cylindrical shape having an inner diameter larger than the outer diameter of the optical fiber core wire 11 and an inner diameter smaller than the maximum outer diameter of the stopper 33, and the terminal protector 1 is made of the optical fiber core wire. 11, the protected portion 31 is surrounded with a gap in the radial direction.

  The protective tube 57 and the stopper 33 are connected by press-fitting the stopper 33 into one side of the protective tube 57 in the cylinder axis direction from the top 33b side. The flexibility of the stopper 33 is that of the protective tube 57. It is set larger than the flexibility.

  Here, “flexibility” is attributed to “hardness”, “shape”, and the like, but in this embodiment, “flexibility” is hardened to avoid an increase in cost due to a complicated shape. Stipulated in that. In other words, the material of the stopper 33 and the protective tube 57 is selected so that the flexibility can be qualitatively evaluated based on the hardness of the material used without considering the factor due to the “shape”. That is, it is sufficient that the hardness of the stopper 33 is smaller than the hardness of the protective tube 57. As a combination thereof, for example, as in this embodiment, the protective tube 57 made of polyethylene terephthalate (Rockwell hardness (M) 95), It is desirable to combine a stopper 33 made of polyvinyl chloride (Rockwell hardness (M) 72).

  By combining the stopper 33 and the protective tube 57 having such hardness, the hole 33a is deformed by press-fitting the stopper 33 having the optical fiber core wire 11 inserted into the hole 33a into the protective tube 57, The protective tube 57 is fixed to the outer periphery of the optical fiber core wire 11 through the stopper 33. More specifically, when the stopper 33 is press-fitted into the protective tube 57 from the top 33b side, the top 33b and the body 33c are compressed and the hole 33a is narrowed (deformed). In this manner, the hole 33a is narrowed, so that a tightening force by the stopper 33 against the optical fiber core wire 11 is generated, and the stopper 33 is firmly fixed near the protected portion 31 of the optical fiber core wire 11. Since the hole 33a is narrowed according to the degree of compression of the stopper 33, the tightening force of the stopper 33 against the optical fiber core wire 11 can be adjusted by the degree of press-fitting of the protective tube 57.

  Next, a method for using the terminal protector 1 will be described.

  This terminal protector 1 is attached to the optical fiber core wire 11 before the optical fiber core wire 11 is polished, for example, after the end of the optical fiber core wire 11 is cut with a disk cutter or the like. At this time, first, only the stopper 33 is attached in the vicinity of the protected portion 31 of the optical fiber core wire 11 so that the tightening force due to the deformation of the stopper 33 with respect to the optical fiber core wire 11 is not generated. That is, as shown in FIG. 11, the protected portion 31 of the optical fiber core wire 11 is inserted into the hole 33 a of the stopper 33 that is not press-fitted into the protective tube 57, and only the stopper 33 is inserted into the optical fiber core wire 11. It is made to latch in the vicinity of the part 31 to be protected (a position 5 mm or more away from the tip of the outer cover 11 b).

  Next, the protective tube 57 is brought close to the top 33b of the stopper 33 so that the protected portion 31 of the optical fiber core wire 11 is accommodated in the protective tube 57, and the protective tube 57 is placed on the top 33b side as shown in FIG. To the inside of the protective tube 57. As a result, the body portion 33c and the top portion 33b of the stopper 33 are compressed, the hole portion 33a is narrowed, and a tightening force is generated by the stopper 33, so that the terminal protector 1 is in the vicinity of the protected portion 31 of the optical fiber core 11. It is firmly fixed to.

  Here, the stopper 33 is not in contact with the outer sheath 11b of the optical fiber core wire over its entire length, but only on the outer sheath 11b of the optical fiber core wire with a small area corresponding to the thickness of the top portion 33b. Since there is no contact, the protective tube 57 connected to the stopper 33 is easily inclined with respect to the fiber axis direction. However, when such a tightening force is generated, the protective tube 57 is centered (protection). The axis of the tube 57 and the fiber axis substantially coincide).

  Then, when processing the protected portion 31 of the optical fiber core wire 11 such as a flat polishing or oblique polishing step, as shown in FIG. 13, the terminal protector 1 (only the stopper 33 with the protective tube 57 removed) is used. May be slid to the side opposite to the protected portion 31 side of the optical fiber core wire 11 and retracted from the protected portion 31 of the optical fiber core wire 11.

  On the other hand, when the optical fiber core wire 11 is not processed, for example, between processes, the terminal protector 1 is slid to the distal end side of the optical fiber core wire 11, and as shown in FIG. The eleven protected parts 31 are protected by surrounding them in the radial direction at intervals. In addition, even if the terminal protector 1 is attached to the optical fiber core wire 11 by making the protective tube 57 transparent, the state of the protected portion 31 of the optical fiber core wire 11 (occurrence of chipping or dirt) is confirmed. Becomes easy.

  Thus, for example, the terminal protector 1 is removed from the optical fiber core 11 before the step of removing the outer cover 11b of the protected portion 31 of the optical fiber core 11 to expose the inner optical fiber. . In this case, after removing the protective tube 57 from the stopper 33, the stopper 33 is slid to the distal end side of the optical fiber core wire 11 and pulled out from the optical fiber core wire 11. At this time, the peripheral wall of the hole 33a of the stopper 33 inevitably comes into contact with the protected portion 31 of the optical fiber core wire 11, but as described above, the tightening force due to the deformation of the stopper 33 is obtained by removing the protective tube 57. And the stopper 33 contacts the optical fiber core wire 11 only in a small area. Therefore, when the stopper 33 is pulled out from the optical fiber core wire 11, the processed portion is hardly damaged.

-Effect-
According to the present embodiment, by using the terminal protectors 1 and 1 that constitute one terminal processing unit together with the holder 2, it is possible to further suppress the occurrence of defects in the optical fiber core wire 11 while maintaining work efficiency. be able to.

  Further, since the flexibility of the stopper 33 is greater than the flexibility of the protective tube 57, the hole 33a of the stopper 33 is deformed by press fitting or fitting the stopper 33 into the protective tube 57. Thereby, since the fastening force by the stopper 33 with respect to the optical fiber core wire 11 is generated, the terminal protector 1 can be reliably stopped at a desired position on the optical fiber core wire 11. Therefore, the terminal protector 1 does not interfere with the work, and the terminal protector 1 does not have to be separated from the terminal more than necessary. Therefore, the time required for attaching / detaching the protector is shortened, and the work efficiency is reduced. Is suppressed.

  Since the hole 33a is deformed as the stopper 33 is compressed, the tightening force of the stopper 33 on the optical fiber core wire 11 can be adjusted by the degree of press-fitting of the stopper 33 into the protective tube 57. Thus, when removing the terminal protector 1 from the optical fiber core wire 11, the stopper 33 and the protective tube 57 are separated, so that the tightening force due to the deformation of the stopper 33 disappears. It becomes easy to pull out from the fiber core wire 11 and the stopper 33 and the protected portion 31 of the optical fiber core wire 11 are difficult to contact.

  On the other hand, since the protective tube 57 is fixed to the outer periphery of the optical fiber core wire 11 via the stopper 33, it does not come into contact with the optical fiber core wire 11. Thereby, in order to protect the protected portion 31 of the optical fiber core wire 11, the terminal protector 1 may be moved to the tip side of the optical fiber core wire 11, or the protected portion 31 of the optical fiber core wire 11. Even if the terminal protector 1 is moved away from the protected portion 31 of the optical fiber core wire 11 to expose the terminal protector 1, the stopper 33 is only in contact with the outer sheath in the vicinity of the protected portion 31. It is difficult to contact the protected part 31 of the core wire 11.

  As described above, even when the protection and exposure of the protected portion 31 of the optical fiber core wire 11 are repeated a plurality of times, the protected portion 31 of the optical fiber core wire 11 is prevented from being damaged and the optical fiber core wire 11 is protected from being damaged. The protection part 31 can be easily protected and exposed.

  Further, since the stopper 33 is formed so that the outer diameter increases from the top 33b side toward the body portion 33c, the stopper 33 is formed in a cylindrical protective tube from the top 33b side where the hole 33a is formed. It becomes easy to press-fit into 57. Furthermore, since the protective tube 57 has an inner diameter smaller than the maximum outer diameter of the stopper 33, the stopper 33 can be reliably deformed by press-fitting the stopper 33 into the protective tube 57.

  Furthermore, since a transparent resin molded product is used as the protective tube 57, the state of the protected portion 31 of the optical fiber core wire 11 protected by the terminal protector 1 can be easily confirmed during terminal processing. .

-Modification of Embodiment 2-
In this modification, the terminal protector 1 having a different structure from the terminal protector using the stopper 33 and the protective tube 57 is used. More specifically, since the terminal protector using the stopper 33 and the protective tube 57 stops at a desired position on the optical fiber core wire 11, the time required for the attachment / detachment can be shortened, but at least when it is worn or removed. Since there is a possibility of contact with the protected portion 31 of the optical fiber core wire 11 in this case, this modification employs a structure in which the optical fiber core wire 11 does not contact the protected portion 31. Hereinafter, the terminal protector 1 of this modification is demonstrated.

  The terminal protector 1 according to this modification is attached to both ends of the optical fiber core 11 bundled with the fiber clip 2, so that the optical fiber core 11 is defective while maintaining the working efficiency together with the fiber clip 2. Used as a terminal processing unit to further suppress In this case, the terminal protector 1 is removed from the optical fiber core wire 11, and one end of the optical fiber core wire 11 is polished. Then, when each step is completed, the terminal protector 1 is attached to the processed end.

  FIGS. 14-19 shows the terminal protector which concerns on this modification, and FIG.20 and FIG.21 shows the terminal protector attached to the optical fiber core wire. This terminal protector 1 is for protecting the protected part 31 of the optical fiber core wire 11.

  In this modification, the protected portion 31 of the optical fiber core wire 11 has a margin (about 5 mm) added to the polished end (processed portion) and the planned processing portion when the outer cover 11b is not removed. When the outer cover 11b is removed, it means a portion obtained by adding an extra length (about 5 mm) to the optical fiber 11a. In the following description, the opening 47 side of the protective cover 7 is the upper side, the bottom wall portion 17 side of the protective cover 7 is the lower side, and the side that is not sandwiched between the clips 3 in the longitudinal direction of the protective cover 7 is the front side. The side sandwiched between the clips 3 in the longitudinal direction of the protective cover 7 is the rear side.

  Moreover, the axial direction of the optical fiber core wire 11 means a direction A in which the central axis of the protected portion 31 (optical fiber strand 11a) of the optical fiber core wire 11 extends as shown in FIG. The radial direction of the optical fiber core wire 11 means a direction D perpendicular to the axial direction A, as shown in FIG. Note that the eight radial directions D shown in FIG. 29B are examples, and other directions extending radially from the central axis are also included in the radial direction D.

  As shown in FIGS. 20 and 21, the terminal protector 1 is configured to surround the protected portion 31 of the optical fiber core wire 11 over the entire circumference. The terminal protector 1 includes a clip (clamping member) 3, a rubber sheet (elastic member) 5, a protective cover (protective member) 7, and a protective tube 9.

  The clip 3 is not limited as long as it is a known clip, but a turn clip (double clip: fixing metal part 15 mm) is preferable from the viewpoint of clamping force and workability, and the turn clip is formed in a substantially isosceles triangular section. And a fixing bracket portion 23 whose top portion (scissor opening) 23a opens and closes, and a pair of opening / closing levers 13 and 13 that face each other and open the scissor opening 23a on the principle of lever. One end (fixed end) of each of the open / close levers 13 and 13 is rotatably connected to the scissor opening 23 a of the fixing bracket 23.

  The fixing bracket 23 is used by the operator to pinch the other end (free end) of the open / close levers 13 and 13 with, for example, the thumb and forefinger, and apply force to both fingers so that the free ends approach each other. Thus, while the scissor opening 23a is opened, the scissor opening 23a is closed by removing the force of both fingers so that the free ends move away from each other. The fixing metal part 23 includes a part of the protective cover 7 in the front-rear direction (longitudinal direction), specifically, a rear part (rear end part) of the protective cover 7 from the center in the front-rear direction, and a protective cover as described later. The clip 3 is attached to the protective cover 7 and the vicinity of the protected portion 31 of the optical fiber core wire 11 is placed between the protective cover 7 and the rubber. The sheet is sandwiched via the sheet 5.

  The rubber sheet 5 is an NBR (acrylonitrile butadiene rubber) sheet, and includes a rubber sheet main body 15 and an auxiliary rubber sheet 25 attached to a central portion in the longitudinal direction of the rubber sheet main body 15 as shown in FIG. ing. As shown in FIGS. 17 and 24, the rubber sheet 5 is overlapped with the rear end portion (overlapping sandwiching portion 7 a) of the protective cover 7 along the inner surface of the protective cover 7 as shown in FIGS. 17 and 24. Thus, the central portion in the longitudinal direction is sandwiched by the fixing bracket portion 23 via the protective cover 7, while both end portions in the longitudinal direction are engaged with the open / close levers 13 and 13. In other words, the rubber sheet 5 is bent in a substantially W shape, and is wound around the W clip in such a manner that the clip having a W-shaped cross section is offset upward.

  The rubber sheet body 15 is formed in a rectangular shape, with four corners being cut off, and insertion holes 15a, 15a,... For inserting the opening / closing levers 13, 13 of the clip 3 are formed at both ends by punching. Are formed two by two. The auxiliary rubber sheet 25 is used to increase the thickness of the rubber sheet 5 so that the adhesion between the rubber sheet 5 and the protective cover 7 sandwiched between the fixing metal parts 23 and the fixing metal part 23 is increased. The rubber sheet body 15 is attached with a double-sided tape (not shown).

  In this way, the clip 3 sandwiches the optical fiber core wire 11 via the rubber sheet 5 so as to elastically sandwich a portion of the outer sheath 11b of the optical fiber core wire. Since the fixing metal part 23 does not directly sandwich the optical fiber core wire 11, peeling of the outer sheath 11 b of the optical fiber core wire 11 and slippage between the fixing metal part 23 and the outer sheath 11 b can be suppressed. That is, the rubber sheet 5 has not only a role as a protective material for the optical fiber core wire 11 but also a role as a brake against sliding of the terminal protector 1.

  The protective cover 7 is formed in an elongated shape (so as to extend in the front-rear direction), and has a bottom wall portion 17, side wall portions 27, 27, and inclined wall portions 37, 37, as shown in FIGS. In addition, the cross section is substantially U-shaped so as to surround the protected portion 31 of the optical fiber core wire 11 from three directions (left and right direction and downward direction) without contacting the optical fiber core wire 11. In other words, it is possible to insert the optical fiber core wire 11, which is defined by the upper ends of the side wall portions 27, 27, into the protective cover 7 from the upper side (the radial direction D of the optical fiber core wire 11). When attached to the optical fiber core 11, an opening 47 is formed that extends substantially parallel (in the front-rear direction) to the axial direction (fiber axial direction) A of the optical fiber core wire.

  The protective cover 7 is formed by bending a transparent laminate film (resin molded product such as polyethylene terephthalate, biaxially stretched polypropylene film) cut into a substantially rectangular shape shown in FIG. 22, and has flexibility. A shallow groove is formed by drawing a fold line with a hard needle or the like at the boundary between the bottom wall portion 17 and the side wall portions 27, 27 and at the boundary between the side wall portions 27, 27 and the inclined wall portions 37, 37. Easy to bend. As shown in FIG. 16, the protective cover 7 is bent so that the bottom wall portion 17 and both side wall portions 27, 27 form a right angle, as shown in FIG. While the opening 47 is formed apart, the bottom wall portion 17 and the side wall portions 27 and 27 are wound around the auxiliary rubber sheet 25 bent at the center on the rear end side as shown in FIG. The upper ends of the side wall portions 27 and 27 are close to each other because the lower end portion is curved in an arc shape and is sandwiched between the scissors openings 23 a of the clip 3.

  The protective cover 7 has flexibility, the rubber sheet 5 overlapped along the inner surface of the protective cover 7 and wound around the clip 3, and the fixing bracket 23 that sandwiches the protective cover 7 from the outside. And sandwiched in a sandwich shape, the opening 47 of the overlapping sandwiching portion 7a (the portion where the rubber sheet 5 is overlapped and sandwiched between the clips 3) opens and closes as the fixing bracket portion 23 opens and closes. Yes. More specifically, the protective cover 7 has an opening 47 formed over the entire length in the front-rear direction when the free ends of the open / close levers 13 and 13 approach each other, and the optical fiber core 11 is moved upward (with respect to the fiber axial direction A). While the free ends of the open / close levers 13 and 13 move away from each other, a part of the opening 47 is closed and fixed near the protected portion 31 of the optical fiber core wire 11. Is done. As a result, as shown in FIG. 20, the protective cover 7 is configured such that the clip 3 holds the optical fiber core wire 11 via the rubber sheet 5, whereby the overlapped sandwiching portion 7 a becomes the protected portion of the optical fiber core wire 11. 31 is fixed in the vicinity.

  Thus, the protective cover 7 fixed in the vicinity of the protected portion 31 of the optical fiber core wire 11 with the clip 3 is from the center in the front-rear direction in the portion on the front side of the overlapped sandwiching portion 7a (hereinafter referred to as the open portion). In the rear portion, the protected portion 31 of the optical fiber core wire 11 is surrounded from three directions in a non-contact state. That is, the protective cover 7 is in a state where the overlapping portion 7a is fixed in the vicinity of the protected portion 31 of the optical fiber core 11, and the front side (one end side of the optical fiber core wire) of the overlapping portion 7a is The optical fiber core wire 11 is not contacted. The protective cover 7 is fitted with the protective tube 9 shorter than the protective cover 7 in the front-rear direction (direction in which the opening 47 extends) and slidable in the front-rear direction with respect to the protective cover 7. .

  The protective tube 9 is obtained by cutting a transparent Sumitube A (trade name) into 20 mm, and has a length approximately half of the open portion. The protective tube 9 is located in a portion of the open portion in front of the center in the front-rear direction in a state where the terminal protector 1 is not attached to the optical fiber core wire 11. When attached to the wire 11, it slides to the rear side of the open portion to cover the protected portion 31 of the optical fiber core wire 11 over the entire circumference.

  Projecting portions 27 a and 27 a projecting upward are formed on the front end portions of the side wall portions 27 and 27 of the protective cover 7 in order to prevent the protective tube 9 from falling off. In addition, on the rear side of the open portion, in order to fix the protective tube 9 that has been slid to the rear side in a tensioned state, it is inclined outward as it goes upward from the upper ends of the side wall portions 27, 27, and the cross-sectional height is increased. Inclined wall portions 37, 37 that expand in a letter shape are formed. The front end portions of the inclined wall portions 37, 37 are formed with corner cut portions 37a, 37a so that the protective tube 9 can smoothly slide to the rear side (so that it can easily ride on the inclined wall portions 37, 37). .

−Assembly and installation procedure of modified terminal protector−
First, as shown in FIG. 23, the auxiliary rubber sheet 25 is attached to the central portion of the rubber sheet body 15 using a double-sided tape. Next, as shown in FIG. 24, the protective cover 7 is superposed using a double-sided tape at the center of the rubber sheet 5 (auxiliary rubber sheet 25) so that the protective cover 7 and the rubber sheet 5 form an inverted T shape. The clamping part 7a (rear end part) is attached.

  Then, as shown in FIG. 25, the rubber sheet 5 is folded so that both ends thereof are directed upward, both side wall portions 27, 27 are perpendicular to the bottom wall portion 17, and the inclined wall portion 37 is formed. , 37 bend the protective cover 7 so as to incline outward as it goes upward. With the protective cover 7, the auxiliary rubber sheet 25, and the rubber sheet main body 15 overlapping in this order from the top, the clip 3 is approached from below, and these are collectively sandwiched as shown in FIG.

  Next, as shown in FIG. 27, both ends of the rubber sheet 5 are folded downward, and the open / close levers 13 of the clip 3 are inserted from the inner side to the outer side with respect to the insertion hole 15 a on the inner side in the longitudinal direction formed in the rubber sheet 5. Then, it inserts so that it may sew from the outer side to the inner side with respect to the insertion hole 15a of a longitudinal direction outer side, and the edge part of the rubber sheet 5 is engaged with the opening-and-closing levers 13 and 13. FIG. As a result, the free ends of the open / close levers 13 and 13 are hidden inside the rubber sheet 5, the repulsive force on the operator's finger when the clip 3 is operated is reduced, and the work is performed by repeating the pinching and fixing work. The burden on the person's finger is reduced. Then, the protrusions 27 a and 27 a are hidden in the protective tube 9, and the protective tube 9 is fitted to the front side of the open portion of the protective cover 7.

  In this state, the protected portion 31 of the optical fiber core wire 11 is brought closer from above the terminal protector 1. Then, when the fixing bracket portion 23 is opened by the opening / closing levers 13 and 13, as shown in FIG. 28, as the scissor opening 23a is opened, the side wall portions 27 and 27 on the rear end side of the protective cover 7 are also opened. The upper ends are opened, and an opening 47 for inserting the optical fiber core wire 11 from above is formed over the entire length of the protective cover 7.

  After the protected portion 31 of the optical fiber core wire 11 fits in the space formed by the protective cover 7, the scissor opening 23a of the fixing bracket portion 23 is closed, and the protective tube 9 is slid along the corner cut portions 37a and 37a. Then, it is slid to the rear side on the open side, and the protection of the protected portion 31 of the optical fiber core wire 11 is completed as shown in FIGS. In addition, even if the terminal protector 1 is attached to the protected part 31 of the optical fiber core wire 11 by making both the protective tube 9 and the protective cover 7 transparent, the protected part 31 of the optical fiber core wire 11 The status (occurrence of chipping or dirt) can be easily confirmed.

  Further, when removing the terminal protector 1, the protective tube 9 is slid forward, and then the open / close levers 13, 13 are operated to open the scissors opening 23 a of the fixing bracket portion 23, so Since the upper ends of the portions 27 and 27 open, the terminal protector 1 can be easily detached from the protected portion 31 of the optical fiber core wire 11.

-Effect of modification-
According to this modification, the optical fiber core wire 11 can be inserted into the protective cover 7 from the radial direction D, and substantially parallel to the fiber axial direction A when attached to the optical fiber core wire 11. Unlike the protector of the type in which the end portion of the optical fiber core wire 11 is inserted into a tube or a through hole, the protected portion 31 of the optical fiber core wire 11 is provided with a protective cover. It can be set inside the protective cover 7 without contacting with it.

  Further, the clip 3 attached to the protective cover 7 by sandwiching the overlapped sandwiching portion 7 a of the protective cover 7 sandwiches the vicinity of the protected portion 31 of the optical fiber core wire 11, thereby overlapping the sandwiched portion of the protective cover 7. 7a is fixed in the vicinity of the protected portion 31 of the optical fiber core 11. In this state, the portion of the protective cover 7 on the front side of the overlapped sandwiching portion 7a does not contact the optical fiber core 11, so that the optical fiber The protected portion 31 can be protected while maintaining the non-contact state of the core 11 with the protected portion 31.

  Further, since the clip 3 holds the vicinity of the protected portion 31 of the optical fiber core via the rubber sheet 5, the slip generated between the clip 3 and the outer cover 11b of the optical fiber core is suppressed, thereby protecting the terminal. While fixing the tool 1 firmly with respect to the optical fiber core wire 11, it can suppress that the jacket 11b of an optical fiber core wire is damaged.

  Thus, the protective cover 7 is configured such that the opening 47 of the overlapped sandwiching portion 7a opens and closes with the opening and closing of the clip 3. Therefore, opening the clip 3 opens the opening 47 of the protective cover 7 with its full length. The terminal protector 1 can be easily attached to the optical fiber core 11 by a series of operations of opening the cover and inserting the protected portion 31 of the optical fiber core wire 11 into the protective cover 7 from the opening 47 and closing the clip 3. Can do. On the other hand, when the terminal protector 1 is removed from the optical fiber core wire 11, it can be easily removed by a completely reverse operation.

  As described above, it is possible to easily attach and detach the optical fiber core wire 11 and to realize a structure in which the optical fiber core wire 11 does not contact the protected portion 31.

  Furthermore, since the protective tube 9 is shorter in the front-rear direction than the protective cover 7 and is slidable in the front-rear direction with respect to the protective cover 7, when the optical fiber core wire 11 is inserted into the protective cover 7 from the opening 47, If the protective tube 9 is retracted from the insertion position, insertion of the optical fiber core wire 11 will not be hindered. Then, after the protected portion 31 of the optical fiber core wire 11 is inserted into the protective cover 7, the protective tube 9 is slid along the protective cover 7 to the insertion position, thereby covering the optical fiber core wire 11. The protection part 31 can be covered over the entire circumference. Thereby, it is possible to suppress the foreign matter (for example, the end portion of another optical fiber core wire) entering from the opening 47 of the protective cover 7 from coming into contact with the protected portion 31 of the optical fiber core wire 11 with a simple structure. it can.

  Further, the clip 3 can realize a structure in which the vicinity of the protected portion 31 of the optical fiber core wire 11 is elastically held with a simple structure using a versatile member, and the thickness of the rubber sheet 5 By changing the above, it is possible to adjust the fixing force generated by the clip 3.

  Further, since a transparent resin molded product is used as the protective cover 7, the state of the protected portion 31 of the optical fiber core wire 11 protected by the terminal protector 1 can be easily confirmed during terminal processing. .

  In the present embodiment, the protected portion 31 including the processed portion of the optical fiber core wire 11 that has been polished or from which the jacket 11c has been removed is protected. However, the present invention is not limited to this, and for example, as shown in FIG. As described above, the ferrule 21 attached to the optical fiber core wire 11 may be protected.
