Description of the Related Art For example, in an operation of butt-connecting an optical fiber by an optical connector (optical connector ferrule) established in JIS C5981 or the like, an optical fiber is inserted into an optical fiber insertion hole formed in the optical connector. (Bare fiber). In this insertion step, the diameter of the optical fiber insertion hole is several tens of micrometers, and the difference in diameter between the optical fiber insertion hole and the optical fiber is as small as several micrometers. I had to. Therefore, it is difficult to improve workability with this work method because it is troublesome, and therefore, there has been a demand for development of an appropriate tool capable of improving work efficiency. In particular, in a multi-core optical connector, the interval between a plurality of formed optical fiber insertion holes is usually about 200 to 300 micrometers, and the work of selecting an optical fiber insertion hole to be inserted is troublesome. Was to hang.

Therefore, as a tool for solving this kind of problem, for example, an optical connector assembling tool as shown in FIG. 7 has been developed. As shown in FIG. 1, the optical connector assembling tool includes a plate-like base 1 installed substantially horizontally, a connector fixing section 3 for supporting and fixing an optical connector 2 on the base 1, and a base 1 A fiber supporting section 5 for moving the optical fiber 4 toward the connector fixing section 3 while supporting the optical fiber 4 thereon.
And The fiber supporting portion 5 supports a fiber moving pedestal 7 that supports the optical fiber 4 sandwiched by the fiber holder 6 so as to be slidable in the X and Y directions on the base 1, and moves the fiber moving pedestal 7 toward the X direction. There is provided a spring 8 for urging and a stopper 9 for restricting excessive movement of the fiber holder 6.

[0004] The connector fixing portion 3 is provided with a distal end surface 2a of the optical connector 2 (the optical fiber 4 inserted into the optical fiber insertion hole).
Surface where the opening where the tip of the is exposed to the outside is formed)
Positioning block 10 connected to the optical fiber 2 for positioning the optical fiber 2, and the positioning block 10
1a is moved toward and away from the optical connector 2 by the operation of 1a,
Further, an urging mechanism 11 for urging the positioning block 10 connected to the distal end surface 2a toward the distal end surface 2a with a spring 12, and an optical connector between the urging mechanism 11 and the positioning block 10 together with the positioning block 10. 2 is provided.

Next, description will be made on the operation of assembling the optical connector 2 to the optical fiber 4 using the optical connector assembling tool. First, the distance between the positioning block 10 and the stopper 13 is increased by operating the operation lever 11a of the urging mechanism 11, and the optical connector 2 is placed at this distance. At this time, the optical connector 2 is arranged such that the front end surface 2 a faces the positioning block 10 and the rear end surface thereof comes into contact with the stopper 13. Then, the optical fiber 4, which has been subjected to pre-processing such as cutting, coating removal, and holding by the fiber holder 6, is fixed on the fiber moving base 7.
Then, the optical fiber 4 is inserted into the optical fiber insertion hole from the rear end side of the optical connector 2 toward the front end side. At this time, the distal end surface of the optical fiber 4 is made to protrude outward by about 0.5 mm from the distal end surface 2a of the optical connector 2.

Next, the positioning block 10 is moved by operating the operation lever 11a.
Connect by pressing against a. Then, the distal end portion of the optical fiber 4 projecting outside from the distal end surface 2a of the optical connector 2 in the previous step is pushed back into the optical fiber insertion hole by the urging force of the spring 12 via the positioning block 10, and The distal end surface of the fiber 4 is positioned flush with the distal end surface 2 a of the optical connector 2. At this time, the optical fiber 4 retreats (moves in the X direction in FIG. 7) together with the fiber 6 sandwiching the optical fiber 4 and applies a force in the direction in which the spring 8 is extended. Accordingly, the urging force of the spring 8 of the fiber support unit 5 and the urging force of the spring 12 of the connector fixing unit 3 generate a butting force of the optical fiber 4 against the positioning block 10. The optical connector 2 and the optical fiber 4 are bonded and fixed with the abutting force being generated. After this, the operation lever 11a
Is operated again to detach the positioning block 10 from the optical connector 2 and then remove it from the optical connector assembling tool, thereby completing the operation of assembling the optical connector 2 into the optical fiber 4.

That is, in the above assembling operation, the tip of the optical fiber 4 in a state of protruding from the tip 2a of the optical connector 2 to the outside is positioned so that the tip is flush with the tip 2a of the optical connector 2. The optical fiber 4 is pushed back into the optical fiber insertion hole by this, and a compressive force consisting of the urging force of the spring 12 and the urging force of the spring 8 is applied to the distal end portion of the optical fiber 4 at the time of this pushing back. The distal end portion that has received the compressive force is compressed in a protruding state without any support from the outside, so that the compressive force deforms the distal end portion, which may adversely affect the optical transmission characteristics of the optical fiber 4. The problem is that there is.

No external force is applied. The pressing pin 28 of the positioning block support 21 is in a state of contact with the pressure receiving portion 30 or not, and the second urging means 27 is not operated.

Next, the positioning block support portion 21 is further slid toward the connector fixing portion 17, and
By completely pushing it down, it is completely locked on the base 15. In this locked state, the position between the positioning block 20 and the optical connector 16 is compressed by the urging force of the first urging means 22, and the joining surface 20a of the positioning block 20 is pressed.
And the joining end face 16c of the optical connector 16 are further matched without any gap. At the same time as the pressing operation of the positioning block support portion 21 is started, the tip portion of the pressing pin 28 presses the pressure receiving portion 30. When the pressure receiving portion 30 moves by receiving the pressing force from the pressing pin 28, the end of the pressure receiving portion 30 rotates the cam 31 b around the support shaft 31 a to drive the drive shaft 3.

Slide toward.

Due to the sliding movement of the fiber support portion 19, as shown in the upper part of FIG. 6, the distal end surface of the optical fiber 18 in the optical fiber insertion hole abuts on the joint surface 20a of the positioning block 20, and the optical connector 16 is connected. End face 16
It is positioned flush with c. The optical fiber 18 at this time
The tip portion of
The urging force of the urging means 27 is received, but the striking force is received while being supported from the outer periphery by the optical fiber insertion hole. In addition, there is no possibility of causing deformation that adversely affects the optical transmission characteristics. FIG. 6 shows a state in which the above operation has been completed.
8 is adhesively fixed to the optical connector 16. After the adhesive is solidified after a while, the optical fiber supporting portion 2 with respect to the base 15 is
The lock state of No. 1 is released and retreated to return to the initial state shown in FIG. Then, the assembling work is completed by removing the optical connector 16 together with the optical fiber 18 from the optical connector assembling tool.

When positioning the distal end surface of the optical fiber 18 using this optical connector assembly tool, the abutting force of the distal end portion of the optical fiber 18 against the positioning block 20 is determined after the positioning block 20 is connected to the optical connector 16. State, that is, the optical fiber 1
Since the distal end of the optical fiber 18 is generated by the urging force of the second urging means 27 in a state where the distal end does not protrude from the optical fiber insertion hole end portion 16b, an excessive compressive force is applied to the distal end of the optical fiber 18. Therefore, it is possible to make the transmission characteristics of the optical fiber hardly affected.
