BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an optical fiber processing in which a fiber holder holding an optical fiber is positioned on a holder set table, and the optical fiber protruding from the fiber holder is cut or polished. The present invention relates to an auxiliary holder for a fiber holder that is attached to a device and extends the holder set table in a direction away from an optical fiber processing position of the optical fiber processing device.

[0002]

2. Description of the Related Art An apparatus for cutting or polishing an optical fiber, such as a fiber cutter for cutting an optical fiber, includes a holder set table on which a fiber holder holding an optical fiber by clamping is set. A structure for processing a target position of an optical fiber protruding from a holder at a predetermined optical fiber processing position is widely adopted. The positioning of the optical fiber with respect to the optical fiber processing position is performed by positioning the fiber holder on the holder set table.

FIGS. 6 to 8 show a fiber cutter 1 as an example of an optical fiber processing apparatus. FIG. 6 is a perspective view, and FIG. 7 is a view of a fiber holder 3 on a holder set table 2 of the fiber cutter 1. This shows the set state (a)
7B is a plan view, FIG. 8B is a front sectional view, and FIG. 8 is a side view of the setting state of FIG. 7B as viewed from the opening end 9b side of the holder housing groove 9. However, illustration of the pressing arm 5 is omitted in FIG. In the drawing, reference numeral 4 denotes a cutting blade, 5 denotes a pressing arm, 6 denotes a pressing lid, 6a denotes a hinge for rotatably supporting the pressing lid 6, and 7a and 7b denote fiber mounting tables.

In FIG. 6, a fiber cutter 1 includes an optical fiber 8 such as a single-core or multi-core optical fiber core.
Is held and set in a holder storage groove 9 formed on the holder set table 2. Thus, the tip of the optical fiber 8 protruding from the fiber holder 3 is moved to the optical fiber processing position 10 (the cutting blade 4).
Cutting position). The fiber holder 3
The optical fiber 8 disposed on the plate-like base 3a is clamped and held by the openable and closable lid 3b.
Are positioned by being housed in positioning grooves formed in the base 3a, and the optical fiber 8 is positioned with respect to the optical fiber processing position 10 by positioning the fiber holder 3 on the holder set table 2. Is done. The holder accommodating groove 9 of the holder set table 2 has a groove width t2 substantially equal to (slightly wider) the width dimension t1 of the fiber holder 3, and the fiber holder 3 accommodated therein is placed in the optical fiber processing position 10
In such a manner as to be guided slidably and slidably in the reciprocating direction with respect to. The cutting blade 4 can reciprocate as shown by an arrow A in FIG. 6, moves to the outside of the fiber cutter 1 until the setting of the fiber holder 3 is completed, and is retracted from the optical fiber processing position 10.
After the optical fiber 8 is positioned at 0, it is general to move to the optical fiber processing position 10. Optical fiber 8
When the holding lid 6 is closed with the and the cutting blade 4 positioned at the optical fiber processing position 10, the optical fiber processing position 10
The optical fiber 8 is sandwiched between the fiber mounting tables 7 a and 7 b on both sides of the optical disk 1 and a pair of holding members 13 provided on the holding lid 6. Since the holding cover 6 is attracted to the holder setting table 2 side by a magnetic attraction force acting between the magnet 11 attached to the holding cover 6 and the holder 12 on the holder setting table 2, the optical fiber 8 is displaced. Press firmly so that it does not. The pressing member 13 is made of an elastic material such as rubber, and there is no fear that the optical fiber 8 is damaged by the pressing. When the pressing arm 5 is rotated as shown by the arrow B, the optical fiber 8 is pressed against the cutting blade 4 by the pillow 5a at the tip of the pressing arm 5 and cut.

[0005]

When the cutting of the optical fiber 8 is completed, a desired projection length (projection length from the fiber holder 3) is obtained for the optical fiber 8 projecting from the fiber holder 3. The fiber holder 3 is brought into contact with an abutting surface 9 a located at the end of the holder storage groove 9 on the optical fiber processing position 10 side.
7 (a) and 7 (b), the optical fiber 8 has the shortest projection length. FIG. 7A,
As shown in (b), a spacer 14 is provided between the spacer 14 and the contact surface 9a.
It is also possible to position the fiber holder 3 housed in the holder housing groove 9 so as to sandwich it, and in this case, a protruding length longer by a length corresponding to the dimension t4 of the spacer 14 is obtained. In order to obtain a relatively long protruding length, for example, it is conceivable to employ a spacer 14 having a large dimension t4. However, the fiber holder 3 can be extended from the opening end 9b farthest from the optical fiber processing position 10 of the holder accommodating groove 9.
If the fiber holder 3 projects greatly, there is a danger that the fiber holder 3 will fall from the holder set table 2. Further, even if the fiber holder 3 does not fall,
However, there is a problem that the installation state of the optical fiber 8 becomes unstable and is not suitable for cutting the optical fiber 8 accurately. In a general holder set table 2 not considering the use of the spacer 14,
Since a marginal dimension is hardly secured to avoid unnecessary enlargement, the above-mentioned problem occurs remarkably, and the present situation is that the protrusion length cannot be made as long as desired. However, preparing a fiber cutter provided with a separate large holder set base or replacing the holder set base with a large one will increase the cost, and will also require the use of fiber cutters and holder set bases. Since the replacement operation is troublesome and the workability of cutting the optical fiber is reduced, the above problem cannot be solved fundamentally.

As a general example, for example, in the case where the fiber holder 3 having a length dimension t6 of 50 mm is applied to the holder accommodating groove 9 having a dimension t5 (groove length) of 36 mm in the extending direction, a spacer is used. Even if the fiber holder 3 is not used, the fiber holder 3 is 14 m from the open end 9 b of the holder storage groove 9.
m protrude. In this case, if it is attempted to extend the protruding length using the spacer 14, the center in the length direction (the center of the dimension t6) of the fiber holder 3 reaches the opening end 9b of the holder accommodating groove 9 with an extension of, for example, 11 mm. Therefore, the installation state of the fiber holder 3 on the holder set table 2 becomes extremely unstable. The protruding length can hardly be extended.

The above problem is not limited to the fiber cutter 1. For example, a polishing machine for polishing the tip of an optical fiber,
In the case of various types of optical fiber processing equipment equipped with a holder set table on which a fiber holder holding an optical fiber is placed, such as an assembly tool for assembling an optical connector at the tip of an optical fiber, a connection tool for butt-connecting optical fibers, and the like, The same can occur when positioning the fiber holder with respect to the optical fiber, and the separation distance between the installation position of the fiber holder and the optical fiber processing position can be easily extended,
In addition, there has been a demand for the development of a technology that can easily position the fiber holder with respect to the optical fiber processing position even when this extension is performed, and that can stably maintain the installation state.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and by attaching the holder set base of the optical fiber processing apparatus to the optical fiber processing apparatus by attaching the holder to the optical fiber processing apparatus, it is possible to further extend the distance from the optical fiber processing position. An object of the present invention is to provide an auxiliary holder for a fiber holder that realizes stable installation of a fiber holder at a remote position and that can easily position the fiber holder with respect to a positioning reference line passing through the optical fiber processing position.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a state in which a fiber holder auxiliary table 20 (hereinafter, may be abbreviated as “auxiliary table”) according to the present invention is attached to a fiber cutter 1 as an optical fiber processing apparatus. 2) is a plan view with the holding lid 6 omitted, (b) is a front sectional view of (a), FIG.
3 is a perspective view showing an attached state of the auxiliary table 20, and FIG. 3 is a perspective view showing the auxiliary table 20. In the drawings, the same components as those in FIGS. 6 to 8 are denoted by the same reference numerals, and description thereof will be simplified.

As shown in FIGS. 1A, 1B and 3,
The auxiliary table 20 extends on a block-shaped auxiliary table main body 21 attached to the holder set table 2 of the fiber cutter 1 and a holder mounting surface 22 provided on the auxiliary table main body 21 to slide the fiber holder 3. It comprises a positioning rail 23 for movably guiding, and an extension rail 24 extending continuously from the positioning rail 23 and provided so as to protrude from the auxiliary base body 21. Each of the positioning rails 23 and the extension rails 24 functions as a positioning rail for positioning the fiber holder 3, and hereinafter these may be collectively referred to as "positioning rails 23, 24". The positioning rail 23 and the extension rail 24 are separate members.

The auxiliary table main body 21 is formed in a block shape from a hard material such as plastic or metal, and is fixed to the side of the holder set table 2 on the side of the opening 9b of the holder accommodating groove 9. It is fixed using. The fixing means is a screw 25 that is screwed to the holder set table 2 through a thin tongue-shaped mounting portion 21a formed on the auxiliary table main body 21 in the figure, but is not limited thereto. Various configurations can be employed. However, as the fixing means, it is more preferable that the auxiliary table main body 21 can be attached to and detached from the holder set table 2. Auxiliary stand body 21
Is fixed to the holder setting table 2 by the fixing means, the holder mounting surface 22 of the auxiliary table main body 21 is positioned on the holder mounting surface 9c on the holder setting table 2 side. The positioning rails 23 and 24 are also positioned and installed at predetermined positions with respect to the holder set table 2.

As shown in FIGS. 1 (a), 1 (b) and 3, each of the positioning rails 23, 24 is in the form of an elongated plate made of a metal plate or the like. These positioning rails 2
Reference numerals 3 and 24 have fixing portions 23a and 24a formed by bending the metal plate vertically, and have an L-shape as a whole. The width dimensions (dimensions perpendicular to the length direction) of the positioning rails 23 and 24 are the same. The positioning rail 23 is attached to the auxiliary table main body 21 by fixing a fixing portion 23 a on the side of the opposing surface 21 b of the auxiliary table main body 21 facing the holder set table 2. It is installed without any positional deviation. On the other hand, the extension positioning rail 24
The fixing portion 24a arranged so as to overlap with the fixing portion 23a of the positioning rail 23 is fixed to the auxiliary table main body 21 to be attached to the auxiliary table main body 21. The extension positioning rail 24 is positioned so as to be continuous with the positioning rail 23, and protrudes outward from the auxiliary base body 21. That is, the positioning rails 23 and 24 extend in opposite directions from the facing surface 21b of the auxiliary base body 21. Fixing part 23 with respect to auxiliary table main body 21
Various configurations can be adopted as the fixing means for fixing the a and 24a. However, in FIGS. 1A, 1B, 2 and 3, etc., the auxiliary base body penetrates through these fixing portions 23b and 24b. A plurality of screws 26 screwed to 21 are illustrated. The fixing portions 23b and 24b are housed in grooves 21c (see FIGS. 4 (a) to 4 (d)) formed in the facing surface 21b of the auxiliary stand main body 21, and are positioned so as not to be shaken. Since the guide part 2 is fixed to the auxiliary base body 21,
3b and 24b are also positioned stably without shaking. As a result, the positioning rails 23 and 24 continue on the same straight line without any step.

FIGS. 4A to 4D are views showing details of the auxiliary table main body 21, wherein FIG. 4A is a side view as viewed from the facing surface 21b side, FIG. 4B is a plan view, and FIG. () Is a side view seen from the opposite side facing (a), and (d) is a front sectional view. FIG.
As shown in (a) to (d), the holder mounting surface 22 of the auxiliary table main body 21 is formed so as to penetrate the side surface of the auxiliary table main body 21 (the upper surface when attached to the holder set table 2). 5 is a flat bottom surface of the holder holding groove 27. The positioning rail 23 is installed at the center in the width direction of the holder mounting surface 22 (see FIG. 5). The groove width t7 of the holder storage groove 27 matches the groove width t2 of the holder storage groove 9 of the holder set table 2. An opening of a screw component 28 (female screw component) fixed so as to be embedded in the auxiliary base body 21 is exposed in the groove 21c.
A screw 26 passing through 3b and 24b is screwed.

As shown in FIGS. 1A and 1B, the auxiliary table 20 extends the holder set table 2 by fixing the auxiliary table main body 21 to the holder set table 2. When the auxiliary table main body 21 is fixed to the holder set table 2 with the screw 26, the holder storage groove 27 of the auxiliary table main body 21 communicates with the holder storage groove 9 of the holder set table 2. The holder mounting surface 22 of the auxiliary table main body 21 is positioned flush with the holder mounting surface 9c of the holder setting table 2, and the holder mounting surface 22 is substantially extended by the holder mounting surface 22. As a result, the fiber holder 3 can be installed using not only the holder mounting surface 9c of the holder set table 2 but also the holder mounting surface 22 on the auxiliary table main body 21.
It is possible to realize the installation of the fiber holder 3 at a position farther from 0 (for example, the fiber holder 3 shown by a virtual line in FIGS. 1A and 1B). As a result, the protruding length t3 obtained by cutting the optical fiber 8 held by the fiber holder 3 can be lengthened.

Incidentally, in the holder set table 2 of the fiber cutter 1 to which the auxiliary table 20 is attached, not only the inner wall surface of the holder storage groove 9 of the holder set table 2 but also the holder mounting surface which is inserted into the holder storage groove 9. The fiber holder 3 is also positioned on a straight line passing through the optical fiber processing position 10 (see FIG. 1A; hereinafter, referred to as a “positioning reference line P”) also by the extension rail 24 installed on 9c. More specifically, in the holder set table 2, a pair of legs 3 c (see FIG. 5) protruding from the bottom of the base 3 a of the fiber holder 3 is provided on the holder mounting surface 9 c exposed on both sides of the extension rail 24. (See FIG. 2), and the fiber holder 3 is attached to the extension rail 2.
4 so that the inner wall surfaces on both sides of the holder accommodating groove 9 come into contact with the base 3 a and the extension rail 24.
The fiber holder 3 is positioned on the positioning reference line P by contact between the fiber holder 3 and the two legs 3c.

On the other hand, the holder mounting surface 22 of the auxiliary table main body 21
Also above, the fiber holder 3 is positioned by the positioning rail 23 on the positioning reference line P passing through the optical fiber processing position 10. Specifically, as shown in FIG.
On the auxiliary table main body 21, both legs 3c of the fiber holder 3 are mounted on the holder mounting surface 22 exposed on both sides of the positioning rail 23, and the fiber holder 3 is installed so as to straddle the positioning rail 23. Accordingly, the positioning is performed on the positioning reference line P by the contact between the positioning rail 23 and the both legs 3c. In addition, in the auxiliary stand main body 21, the inner wall surfaces on both sides of the holder storage groove 27 also function for positioning the fiber holder 3.

When the fiber holder auxiliary table 20 is attached to the holder set table 2, for example, the fiber holder 3 protrudes from the holder mounting surface 9c of the holder set table 2 and extends to the holder mounting surface 22 of the auxiliary table body 21. Even when the fiber holder 3 is installed, the fiber holder 3 is positioned on the positioning reference line P by the continuous positioning rails 23, 24 and the like, and it is hard to cause inconvenience such as being inclined with respect to the positioning reference line P. As a result, The work of cutting the optical fiber 8 can be performed accurately. In the configuration in which the fiber holder 3 is positioned by the positioning rails 23 and 24, the accuracy of forming the inner wall surfaces on both sides of the holder accommodating grooves 9 and 27 of the holder set table 2 and the auxiliary table 20 is reduced, or these inner wall surfaces are replaced with the fiber holder. The fiber holder 3 can be positioned even when the fiber holder 3 is not contacted. In particular, the configuration in which the fiber holder 3 is positioned by the positioning rails 23 and 24 that are continuous with each other is different from the mounting surfaces 9 c and 2.
It is suitable for positioning the fiber holders 3 mounted over the two on a common straight line (positioning reference line P), for example, without being affected by minute dimensional tolerances between the holder accommodating grooves 9c and 27. , Positioning rails 23, 24
Thus, there is an advantage that the fiber holder 3 can be easily positioned on the positioning reference line P. Even when the auxiliary table 20 is attached, the operation of cutting the optical fiber 8 with the fiber cutter 1 is no different from the case where the auxiliary table 20 is not attached. Further, after the optical fiber 8 is cut, there is no change in the operation of taking out the fiber holder 3 from the fiber cutter 1.

Optical fiber 8 held in fiber holder 3
In order to obtain the desired projection length by cutting the fiber, it is necessary to press the fiber holder 3 against the contact surface 9a of the holder accommodating groove 9 and securely abut the fiber holder 3 (when a spacer is used, the fiber holder 3 is used). The spacer pressed by 3 against the contact surface 9a), and the fiber holder 3 is slidably stored along the positioning reference line P in the holder storage grooves 9 and 27 of the holder set table 2 and the auxiliary table 20. Is preferred. As described above, in the fiber cutter 1 to which the auxiliary table 20 is attached, the holder mounting surface 9c of the holder set table 2 and the holder mounting surface 22 of the auxiliary table main body 21 are flush with each other, and the fiber holder 3 Mounting surface 9c,
22, positioning rails 23, 24 connected to each other
, Can be slid smoothly along the positioning reference line P. Therefore, the operation of pressing the fiber holder 3 toward the contact surface 9a can be efficiently performed by the slide movement.

1A and 1B, the holder mounting surface 9 is shown.
Although the extension rail 24 having the length reaching the central portion of c is illustrated, the invention is not limited to this, and the extension rail having a dimension that reaches the contact surface 9a may be employed. is there. Thereby, the positioning rail can be arranged over the entire area where the fiber holder 3 can be placed. In the configuration in which the positioning rail 23 and the extension rail 24 are separate members, by replacing only the extension rail, the extension rail installed on the holder mounting surface 9c can have the desired length dimension. Is easily obtained. Further, since the positioning rail 23 does not need to be replaced, only the extension rail having a simple configuration having a required size may be prepared, and the cost is reduced as compared with a configuration in which all the positioning rails provided on the auxiliary base body are replaced. it can.

As the metal plate forming the positioning rails 23 and 24, it is more preferable to use a magnetic material (magnetic material) magnetized so that the magnetic material on the fiber holder 3 side can be magnetically attracted (magnet or separately provided). Magnetic body magnetized by the magnet). In this case, a fiber holder whose base and lid are formed of a magnetic material (ferromagnetic material) such as iron or a fiber holder in which a magnetic material (ferromagnetic material) is incorporated are placed on the holder mounting surfaces 9c and 22. Simultaneously with the placement, the positioning rails 23, 24 on the holder placement surfaces 9c, 22 are attracted by the magnetic attraction force, so that the lifting is prevented. In order to perform the cutting operation of the optical fiber 8 accurately, not only the wobble and the like of the fiber holder 3 on the holder mounting surfaces 9c and 22 are prevented to prevent the displacement and inclination with respect to the positioning reference line P, but also the holder mounting. Since it is preferable to prevent the fiber holder 3 from rising from the placement surfaces 9c and 22, it is preferable to employ a configuration in which the fiber holder 3 is magnetically attracted by the positioning rails 23 and 24 to prevent the fiber holder 3 from rising. Work can be performed more accurately and reliably. Positioning rail 23, 2
In view of the fact that the magnetic attraction force of 4 is effectively applied to prevent the fiber holder 3 from floating, the base 3a of the fiber holder 3 is formed of a magnetic material, and the base 3a is magnetically attracted to the positioning rails 23 and 24. It is preferable to employ it. When the base or lid is formed of a magnet or the base or lid made of a magnetically attractable magnetic material is magnetized by a magnet separately incorporated in a fiber holder, the positioning rails 23 and 24 may be used. Must be adjusted so that the fiber holder can be magnetically attracted. The positioning rails 23 and 24 may themselves be permanent magnets. For example, a magnet in which a metal plate (magnetic or ferromagnetic) forming these positioning rails 23 and 24 is incorporated in the auxiliary base body 21. May be used.

It is more preferable that the extension rail 24 capable of magnetically attracting the fiber holder 3 reaches the contact surface 9 a of the holder storage groove 9 of the holder set table 2. It is preferable to dispose it near the built-in pad 12. That is, when the holding lid 6 is closed, the fiber holder 3 may be attracted and lifted by the magnetic attraction of the magnet 11 of the holding lid 6, but the extension rail 2 capable of magnetically sucking the fiber holder 3 may be provided.
If the magnet holder 11 is disposed near the presser foot 12 to cancel the magnetic attraction of the magnet 11, the fiber holder 3 can be prevented from floating.

The optical fiber processing apparatus to which the auxiliary holder for a fiber holder of the present invention can be applied is not limited to the fiber cutter 1, but includes a polishing machine, an assembling tool for assembling an optical connector at an optical fiber tip, and abutting optical fibers. Various configurations such as a connection tool for connection can be adopted. Further, the positioning rail attached to the auxiliary table main body only needs to include at least the extension rail 24, and thereby the fiber holder can be positioned even at the end of the holder set table separated from the optical fiber processing position. A configuration including the positioning rail 23 in addition to the extension rail 24 is more preferable because the fiber holder can be stably positioned even at the end of the auxiliary stand separated from the optical fiber processing position. The positioning rail 23 is not limited to a member made of a member different from the extension rail 24, and may be a member entirely made of one member including the extension rail protruding from the auxiliary table main body.

[0025]

As described above, according to the auxiliary holder for a fiber holder of the present invention, the holder set base can be substantially extended by being attached to the optical fiber processing equipment, and can be extended from the optical fiber processing position. Since it is possible to install the fiber holder at a more distant position, it becomes possible to process the optical fiber protruding from the fiber holder at a position further distant from the fiber holder, and the optical fiber protruding from the fiber holder Can be widely used depending on the intended processing position. In addition, the holder mounting surfaces of the holder set table and the fiber holder auxiliary table are positioned flush with each other, and the fiber holder is positioned by the positioning rail that is continuous from the holder set table to the auxiliary table. Even if the fiber holder is set on the holder mounting surface of the fiber holder auxiliary table, it can be stably positioned on the positioning reference line, so that the optical fiber can be accurately positioned with respect to the optical fiber processing position, and the optical fiber can be accurately processed It has an excellent effect of being able to do it.

According to the auxiliary holder for a fiber holder of the present invention, since the positioning rail provided on the holder mounting surface of the auxiliary holder main body and the extension rail are separate members. By selecting and using only the members that form the extension rails, an excellent effect is obtained in that the extension rails can easily obtain a desired projecting dimension from the auxiliary base body.

According to the fiber holder auxiliary table, the magnetic material provided on the fiber holder is attracted by the magnetic attractive force applied to the magnetic material provided on the positioning rail. Since the floating of the fiber holder from the holder mounting surface of the holder setting table or the auxiliary table main body can be prevented, the optical fiber can be accurately positioned at the optical fiber processing position, and the optical fiber can be processed accurately.
