Field of the Invention The present invention relates to a fiber used when a fiber holder supporting an optical fiber is set in an optical fiber processing apparatus and cut or polished. The present invention relates to a holder jig. 2. Description of the Related Art FIGS. 3 and 4 show a conventional fiber holder jig. In FIG. 3, reference numeral 1 denotes an optical fiber cutting machine as an optical fiber processing device, 2 denotes a clamp lid, 3 denotes a cutter, 4 denotes a holder storage groove, 5 denotes a fiber holder, and 6 denotes a fiber holder jig. The fiber holder 5 includes a plate-shaped base 8, an optical fiber receiving groove 10 formed on the upper surface 9 of the base 8, and an optical fiber 11 (optical fiber core) stored in the optical fiber receiving groove 10. And a lid 12 which can be opened and closed to clamp the base between the base and the base 8. When the fiber holder 5 is inserted into the holder mounting groove 4 of the optical fiber cutting machine 1, the optical fiber 11 clamped and supported by the fiber holder 5 becomes horizontal, and the portion of the optical fiber 11 protruding from the fiber holder 5 becomes The pressing plate 7 located immediately above the disk-shaped cutter 3 provided adjacent to the holder accommodating groove 4 and disposed in the vicinity of the cutter 3 is rotated in the direction of arrow A in FIG. Is pressed. The cutter 3 is driven to rotate about a horizontal axis, and cuts the optical fiber 11 pressed by the holding plate 7. [0004] The clamp lid 2 rotates on the cutting machine body 13 about a rotation shaft 2a, and opens and closes the holder accommodating groove 4 opened on the cutting machine body 13. When the clamp lid 2 is closed on the upper surface of the upper surface of the cutting machine main body 13, the clamp lid 2 is attracted and fixed on the cutting machine main body 13 by the magnet 2 b also serving as a spacer, and presses the fiber holder 5 housed in the holder housing groove 4. Moreover, the spring 2c attached to the clamp lid 2
Presses and holds down the fiber holder 5, thereby preventing the fiber holder 5 from being displaced or vibrating when the optical fiber 11 is cut by the cutter 3, and cutting the optical fiber 11 accurately. it can. Further, when the clamp lid 2 is opened, the clamp lid 2 is reliably pushed upward and released simultaneously with the release of the magnetic attraction of the magnet 2b when the clamp lid 2 is released, and the clamp lid 2 bites into the fiber holder 5 to make opening difficult. Prevent from becoming. [0005] The fiber holder jig 6 is a generally flat block made of a hard material such as metal or resin, and is housed in the holder housing groove 4 together with the fiber holder 5. The fiber holder jig 6 is sandwiched between a holder contact wall 14 protruding from the end of the holder storage groove 4 on the cutter 3 side and the fiber holder 5 stored in the holder storage groove 4. Then, the fiber holder 5 in the holder accommodating groove 4 is positioned at a target distance from the cutter 3 by the dimension t acting as a spacer of the fiber holder jig 6. At this time, as shown in FIG.
Optical fiber 11 clamped and held in fiber holder 5
The vicinity of the tip 11a projecting from the fiber holder 5 is cut by contact with the cutter 3 driven to rotate, so that the optical fiber 11 projecting from the fiber holder 5 has a desired projection length. The vicinity of the upper end of the cutter 3 corresponds to an optical fiber processing position where the optical fiber 11 is cut. [0006] In the case of the fiber holder jig 6 as described above, the optical fiber processing position (in the case of the optical fiber cutting machine 1, near the upper end of the cutter 3).
Although the fiber holder 5 can be accurately positioned at a target distance with respect to the optical fiber 11, there is nothing supporting the optical fiber 11 extending from the fiber holder 5 to the cutter 3, so that the optical fiber 11 is bent and bent. May be disconnected. If the optical fiber 11 is bent and cut, there arises a problem that a desired connection loss cannot be obtained when the optical fiber 11 is butt-connected to another optical fiber in a later step. For this reason, in the jig 6 for a fiber holder,
There is a limit in increasing the dimension t acting as a spacer, and there has been dissatisfaction that the protruding length of the optical fiber 11 from the fiber holder 5 cannot be increased. Also, in view of the above-mentioned problem, a technology has been developed that can stably and accurately cut the optical fiber 11 by the cutter 3 even when the length of the optical fiber 11 protruding from the fiber holder 5 is long. Was required. [0007] The above-mentioned problems are not limited to the optical fiber cutting machine.
The same applies to various types of optical fiber processing equipment such as an optical connector mounting tool for inserting the optical fiber 11 supported by the optical connector 11 into the optical connector. Problems such as a decrease in processing accuracy due to bending of the eleventh cannot be avoided. SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and provides a fiber holder jig capable of preventing bending of an optical fiber supported in a protruding state on a fiber holder and improving processing accuracy by an optical fiber processing device. It is intended to provide. [0009] In order to solve the above-mentioned problems, the present invention comprises a rigid main body, and elastic bodies fixed on both sides of the main body. A positioning groove for storing and positioning the optical fiber is formed,
Machining the holder accommodating groove provided in the optical fiber processing equipment to perform the optical fiber, are housed removably with fiber holder for supporting the optical fiber, the fiber holder of the holder accommodating grooves are contact Thereby, the holder abutting wall that regulates the movement of the optical fiber processing device in the optical fiber processing position direction, and the holder abutting wall is interposed between the fiber holder and the holder abutting wall by the main body. ensuring the distance between the fiber holder, and the elastic body is the holder
The optical fiber, which is stably stored in the holder storage groove by being in contact with the both side walls of the storage groove and fitted in the holder storage groove, is stored in the positioning groove in the optical fiber supported by the fiber holder. A jig for a fiber holder, characterized in that the jig is positioned in such a manner as to solve the above problem. The fiber holder jig is housed in the holder housing groove such that the main body portion comes into contact with the holder abutting wall. At this time, the elastic portions fixed on both sides of the main body are brought into pressure contact with the inner walls of the holder storage grooves on both sides of the holder contact wall, and are fitted into the holder storage grooves. The tool is stably stored in the holder storage groove. Therefore, when the fiber holder accommodated in the holder accommodating groove is brought into contact with the main body and the main body is sandwiched between the main body and the holder abutting wall, the fiber holder becomes the main body of the fiber holder jig. The jig for the fiber holder is separated from the optical fiber processing position by the optical fiber processing device by the dimension, and the jig for the fiber holder functions as a spacer for setting the separation distance from the optical fiber processing position of the fiber holder. Therefore, the distance of the fiber holder from the optical fiber processing position can be adjusted only by changing the dimensions of the main body by exchanging the fiber holder stored in the holder storage groove, and processing the optical fiber supported by the fiber holder. The position can be easily adjusted. The optical fiber supported in the protruding state by the fiber holder is positioned in the optical fiber processing position of the optical fiber processing equipment by being housed in the positioning groove of the fiber holder jig, so that the optical fiber from the fiber holder is Even if the protrusion length is increased, bending or the like can be prevented. Therefore, the optical fiber can be accurately processed at the optical fiber processing position. Various configurations such as a V-groove, a U-groove, and a circular groove can be adopted as the positioning groove. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of a jig for a fiber holder according to the present invention will be described below with reference to FIGS. In the present embodiment, an example of application to the optical fiber cutting machine 1 will be described as an optical fiber processing device, and in the drawings, the same components as those in FIGS.
The description will be simplified. In FIG. 1, a jig 15 for a fiber holder according to the present embodiment includes a main body 16 formed in a block shape from a material having sufficient rigidity such as metal or resin, and two opposing sides of the main body 16. And elastic members 17, 17 fixed to the holder housing groove 4.
In contact with the side walls 4a, 4a of the holder storage groove 4 so as to be taken out at a target position (near the holder contact wall 14). Here, the fiber holder jig 1
5 is an elastic body portion 1 made of an elastically deformable material such as rubber.
Since the fiber holders 7 and 17 are slightly elastically deformed and are dimensioned to be accommodated in the holder accommodating groove 4, the fiber holder jig 15 accommodated in the holder accommodating groove 4 has the side walls 4a and 4a.
a, and is stably accommodated without any displacement. The center of the upper surface 16a of the main body 16 has a V
A positioning groove 18 which is a groove is formed. The positioning groove 18 has a contact surface 19 that is in contact with the holder contact wall 14.
And a contact surface 20 (see FIG. 2) formed on the opposite side to the contact surface 19. As shown in FIG. 1, a fiber holder jig 1 is
When the holder 5 is stored, the positioning groove 18 extends in a direction corresponding to the direction in which the fiber holder 5 stored in the holder storage groove 4 moves forward and backward with respect to the cutter 3. When cutting the optical fiber 11 using the fiber holder jig 15, the contact surface 19 of the fiber holder jig 15 housed in the holder housing groove 4 is changed to the holder abutting wall 14.
The fiber holder 5 housed in the holder housing groove 4 is moved in the direction of the cutter 3 to abut on the abutting surface 20 of the main body 16 of the fiber holder jig 15. As a result, the fiber holder 5 is positioned away from the holder contact wall 14 by the effective dimension L of the main body 16 (dimension between the contact surfaces 19 and 20). In the fiber holder 5,
Since the optical fiber 11 is clamped and supported, and the optical fiber 11 has a sufficient protruding length from the fiber holder 5, the fiber holder 5 moved in the holder accommodating groove 4 is used as a jig for the fiber holder. 15, the optical fiber 1 supported in a protruding state by the fiber holder 5.
1 is stored so as to penetrate into the positioning groove 18 of the fiber holder jig 15, and reaches the optical fiber processing position by the cutter 3. The main body 16 is preferably formed of a material having high corrosion resistance, such as stainless steel, so that an error in the effective dimension L due to rust or the like can be prevented. The optical fiber 11 can be cut by driving the holding plate 7 and pressing the optical fiber 11 against the cutter 3 being driven in rotation. The projected size of the cut optical fiber 11 from the fiber holder 5 is longer by the effective dimension L of the main body portion 16 than when the cut is performed without using the fiber holder jig 15. Therefore, when a jig for a fiber holder having a main body part having a different effective dimension L is employed, the length of projection of the optical fiber 11 from the fiber holder 5 can be adjusted. As shown in FIG. 2, when the optical fiber 11 is cut, the optical fiber 11 is positioned by being housed in the positioning groove 18, so that even if the optical fiber 11 comes into contact with the cutter 3, a positional shift may occur. And bends between the cutter 3 and the fiber holder 5 are also prevented.
Can be cut accurately. Further, even when a jig for a fiber holder having a large effective dimension of the main body is applied to extend the length of the optical fiber 11 protruding from the fiber holder 5, the separation distance from the cutter 3 to the fiber holder 5 increases, Accompanying this, the optical fiber 11 extending from the cutter 3 to the fiber holder 5 also becomes longer. However, by storing the optical fiber 11 in the positioning groove 18, misalignment and bending are prevented. Therefore, the intended cutting can be performed, the intended cut surface can be stably obtained, and the processing accuracy is improved. Therefore, even when the protruding length of the optical fiber 11 from the fiber holder 5 is lengthened, accurate cutting can be performed, and the desired protruding length can be accurately obtained in the optical fiber 11, and the target cut surface is stable. Is obtained. The positioning groove 18 is formed on the upper surface 16 of the main body.
Since the taper shape gradually narrows as going downward from a, and the opening amount of the main body upper surface 16a is increased, the insertion of the optical fiber 11 into the positioning groove 18 is easy. Further, the optical fiber 11 supported by the fiber holder 5 in a protruding state can be inserted from a portion of the positioning groove 18 opened to the contact surface 20. When the cutting of the optical fiber 11 is completed by the optical fiber cutting machine 1, the fiber holder 5 is placed in the optical fiber 1
While supporting the optical fiber 1, the optical fiber 11 is sequentially transferred to an optical fiber processing device such as a coating remover and a polishing machine (not shown), and the tip of the optical fiber 11 is subjected to a processing such as coating removal and polishing. In each optical fiber processing device such as a coating remover and a polishing machine, the optical fiber 11 supported by the fiber holder 5 is stored in the holder storage groove provided in each of the optical fiber processing devices. Is positioned at the optical fiber processing position. Here, similarly to the optical fiber cutting machine 1, for each optical fiber processing equipment such as a coating remover, a polishing machine, etc., selection of use / non-use of a fiber holder jig and a fiber holder applied to a holder storage groove are provided. The processing position of the optical fiber 11 can be easily adjusted by selecting a jig for use (selecting an effective dimension of the main body). After the ends of the optical fiber 11 are processed so that they can be butt-connected, for example, as an optical fiber processing device, the fiber holder 5 is transferred to a holder accommodating groove of an optical connector mounting tool for supporting the optical connector.
Is moved toward the optical connector supported by the connector support base, thereby connecting the optical fiber 11 to the optical connector (specifically, a ferrule or a connection for connecting the optical fiber 11 previously inserted into the ferrule to the optical fiber 11). Mechanism).
Also in this case, by selecting whether to use the fiber holder jig or not, and by selecting the fiber holder jig to be applied to the holder storage groove (selecting the effective dimensions of the main body),
The insertion length of the optical fiber 11 into the optical connector can be easily adjusted. As described above, when the use or non-use of the fiber holder jig 15 is selected or when the fiber holder jig having the main body of the target size is selected and used, the optical fiber supported by the fiber holder 5 can be used. The processing position by the 11 optical fiber processing equipment can be easily adjusted. This effect is not limited to the optical fiber cutting machine 1 and the optical connector mounting tool, but can be similarly obtained for various optical fiber processing devices that perform coating removal, polishing, and the like. In the cutting step, in each processing step such as polishing after the cutting, it is also possible to transfer the fiber holder jig together with the fiber holder 5 between the optical fiber processing devices. If the storage position of the fiber holder jig is constant with respect to the processing position of the optical fiber processing equipment, the optical fiber 11 can be easily moved by moving the fiber holder 5 and the fiber holder jig together. Can be positioned. In addition, the optical fiber processing equipment in each processing step does not need to be provided with a separate function for adjusting the position of the fiber holder 5 and the like. It can be handled at a small cost. The jig for a fiber holder according to the present invention comprises:
The configuration is not limited to the configuration described in the embodiment, for example, a structure in which the main body is fixed by being embedded in the elastic body,
Various configurations can be adopted, such as a structure in which an elastic body portion of another part is fixed to both sides of the main body portion so as to face each other. Needless to say, this fiber holder jig can also be applied to various optical fiber processing equipment other than the optical fiber cutting machine 1 and the optical connector mounting tool. The fiber holder is not limited to the above-described embodiment, and various configurations such as a configuration in which an optical fiber is fixed by a method other than clamping can be adopted. As described above, according to the fiber holder jig of the present invention, the fiber holder is housed together with the fiber holder in the holder housing groove of the optical fiber processing equipment, and the holder contact wall and the fiber holder are held. By simply arranging the main body portion between them, the position of the optical fiber supported by the fiber holder in a protruding state by the optical fiber processing device can be easily adjusted by selecting the main body dimension. Also, the jig for the fiber holder has a simple configuration,
Since the cost can be reduced, the processing position of the optical fiber can be easily adjusted with a small cost. Furthermore, since the optical fiber supported in the protruding state by the fiber holder is housed in the positioning groove and positioned, it is possible to prevent misalignment or bending during processing by the optical fiber processing device, and to process the optical fiber by the optical fiber processing device. Accuracy can be improved. Accordingly, even when the length of the optical fiber protruding from the fiber holder is long, the optical fiber can be accurately processed, and an excellent effect that the protruding length of the optical fiber can be increased is achieved.
