  Prior to the description of the embodiments, the optical connector plug will be described. The optical connector plug is, for example, an MPO (MPO: Multifiber Push On) optical connector plug established by Japanese Industrial Standard JISC5982 and International Electrotechnical Commission IEC 1754-7.

  FIG. 1A is a schematic perspective view of the optical connector plug 200. Referring to FIG. 1A, the optical connector plug 200 includes a main body and a lever 202. The optical connector plug 200 has the front side connected to the socket. An optical cable or the like is provided on the main body. The lever 202 is provided so as to cover a part of the ferrule 201 at the front end of the main body. The lever 202 can move relative to the main body, and a slidable range in the front-rear direction with respect to the main body is defined. The lever 202 is biased forward by a spring or the like. The lever 202 covers the recess 203 of the ferrule 201 when no external force other than the spring is applied. FIG. 1B is a partially transparent front view of the optical connector plug 200. Referring to FIG. 1B, the ferrule 201 is provided with a recess 203.

  FIG. 1C is a diagram when the optical connector plug 200 is inserted into the socket 300. Referring to FIG. 1C, the socket 300 is provided with an internal lock 301 for fitting into the recess 203 of the ferrule 201. With reference to FIG. 1D, when the optical connector plug 200 is inserted into the socket 300 while the main body of the optical connector plug 200 is supported, the recess 203 is exposed by the internal lock 301 pushing the lever 202 backward. In other words, when the optical connector plug 200 is inserted into the socket 300 in a state where the lever 202 is slidable, the recess 203 is exposed by the internal lock 301 pushing the lever 202 backward.

  Thereby, the internal lock 301 is fitted into the recess 203. Even if the optical connector plug 200 is inserted into the socket 300 while the lever 202 is supported, the lever 202 cannot be slid and the internal lock 301 cannot push down the lever 202. Referring to FIG. 1 (e), when the internal lock 301 is fitted into the recess 203, the lever 202 is moved forward by the urging force to cover the internal lock 301. Thereby, the lever 202 locks the socket 300. Through the above process, the optical connector plug 200 is connected to the socket 300.

  Even if the optical connector plug 200 is separated from the socket 300 while the main body of the optical connector plug 200 is supported, the lever 202 cannot slide. In this case, the fitting between the internal lock 301 and the recess 203 is maintained, and the optical connector plug 200 cannot be removed from the socket 300. In other words, the optical connector plug 200 cannot be removed from the socket 300 unless the lever 202 is slidable. On the other hand, if the optical connector plug 200 is separated from the socket 300 while the lever 202 is supported, the main body moves forward, so that the fitting between the internal lock 301 and the recess 203 can be released. In other words, the optical connector plug 200 can be removed from the socket 300 by making the lever 202 slidable in the optical connector plug 200.

  As described above, since the part to be supported at the time of insertion is different from the part to be supported at the time of removal, it is difficult to insert / remove the optical connector plug 200 to / from the socket 300 unless touched by a person. Accordingly, it is difficult to omit the extension optical cable by plugging in the printed board having the socket mounted on the rear end from the front of the plug-in device and directly connecting the socket to the optical connector plug for external line. Therefore, in the following embodiments, a plug-in mounting structure, an optical connector plug, and an adapter that can be inserted into and removed from a socket without human intervention will be described.

  Embodiment 1 is an example of a configuration in which a lock mechanism is provided in an optical connector plug, and the optical connector plug is inserted into and removed from the socket via an adapter so that the optical connector plug can be inserted into and removed from the socket without a human hand. . FIG. 2 is a view for explaining how the optical connector plug 10 is inserted into the adapter 20. Referring to FIG. 2, the optical connector plug 10 includes a main body and a lever 12.

  The lever 12 is provided so as to cover a part of the ferrule 11 at the front end of the main body. The ferrule 11 is provided with a recess 13 as in FIG. The lever 12 can move relative to the main body, and a slidable range in the front-rear direction with respect to the main body is defined. The lever 12 is biased forward by a spring or the like. The lever 12 covers the recess 13 of the ferrule 11 when no external force other than the spring is applied. The lever 12 includes a first lock 14 that protrudes forward and has a reduced diameter portion in the middle of the front-rear direction. That is, in the 1st lock | rock 14, a front-end | tip part and a rear-end part have a larger diameter than a reduced diameter part. Since the first lock 14 is fixed to the lever 12, the first lock 14 is interlocked with the lever 12.

  The adapter 20 is fixed to a backplane 40 provided at the rear end of the plug-in device. The adapter 20 may be fixed to the backplane 40 with play by providing a gap between the screw plate 41 and the backplane 40. This play can absorb misalignment between the optical connector plug 10 and the socket 30.

  In the adapter 20, a second lock 21 is provided at a position where the optical connector plug 10 is inserted. When the optical connector plug 10 is inserted into the adapter 20, the second lock 21 is engaged with a portion behind the lever 12 of the optical connector plug 10 to move the main body of the optical connector plug 10 backward. Lock it so you can't. As an example, the second lock 21 fixes the main body of the optical connector plug 10 from above and below.

  FIG. 3A is a perspective view illustrating a state before the optical connector plug 10 is inserted into the adapter 20. The adapter 20 is provided with a lock receiver 22 for the first lock 14. When the optical connector plug 10 is inserted into the adapter 20, the distal end portion and the reduced diameter portion of the first lock 14 can pass through the lock receiver 22. When the front end portion and the reduced diameter portion of the first lock 14 pass through the lock receiver 22, the front end portion and the rear end portion of the first lock 14 are engaged with the lock receiver 22, whereby the lever 12 is locked. FIG. 3B is a perspective view illustrating a state after the optical connector plug 10 is inserted into the adapter 20.

  FIG. 4 is a side view showing a state after the optical connector plug 10 is inserted into the adapter 20. FIG. 5 is an enlarged view of the vicinity of the adapter 20 of FIG. With reference to FIG. 5, there is a gap between the tip of the reduced diameter portion of the first lock 14 and the lock receiver 22 in a state where the second lock 21 supports the main body of the optical connector plug 10. That is, the lock receiver 22 locks the first lock 14 with play in the front-rear direction. In this state, the lever 12 can be slid rearward by the gap.

  FIG. 6 is a view for explaining a state in which the optical connector plug 10 locked to the adapter 20 and the socket 30 are connected. Referring to FIG. 6, socket 30 is mounted on the rear end of printed wiring board 50. The printed wiring board 50 is inserted from the front to the rear of the plug-in device. Thereby, the socket 30 and the optical connector plug 10 are connected.

  7 to 10 are enlarged views of the vicinity of the adapter 20. Referring to FIG. 7, the socket 30 is provided with an internal lock 31 for fitting into the recess 13 of the ferrule 11. When the socket 30 is moved rearward, the internal lock 31 moves toward the recess 13 along the groove (guide) 15 of the ferrule 11. Referring to FIG. 8, when the socket 30 is further moved rearward, the internal lock 31 hits the lever 12.

  Referring to FIG. 9, when the socket 30 is further moved rearward, the rearward movement of the optical connector plug 10 is locked by the second lock 21, so that the internal lock 31 pushes the lever 12 downward. The recess 13 is exposed. Thereby, the internal lock 31 is fitted into the recess 13. In the state of FIG. 9, in the optical connector plug 10, the lever 12 is pushed backward relative to the main body. In other words, the main body of the optical connector plug 10 is drawn forward relative to the lever 12. Referring to FIG. 10, when the internal lock 31 is fitted in the recess 13, the lever 12 returns to the front by the biasing force of the spring. Through the above process, referring to FIG. 11, the connection between the socket 30 and the optical connector plug 10 is completed.

  Referring to FIG. 12, before inserting the optical connector plug 10 into the adapter 20, the printed wiring board 50 may be inserted into the plug-in device. In this case, since the socket 30 is in a position where it can be connected to the optical connector plug 10, the optical connector plug 10 and the socket 30 can be connected by inserting the optical connector plug 10 into the adapter 20.

  Next, how the socket 30 is removed from the optical connector plug 10 will be described. Referring to FIG. 13, when the socket 30 is moved forward, the rear end portion of the first lock 14 is locked to the lock receiver 22, so that the main body of the optical connector plug 10 moves forward as the socket 30 moves. Move to. Thereby, since the lever 12 is separated from the internal lock 31, the fitting between the internal lock 31 and the recess 13 can be released. Referring to FIG. 14, when the socket 30 is further moved forward, the internal lock 31 is separated from the recess 13. Thereby, the socket 30 can be removed from the optical connector plug 10.

  According to this embodiment, when the socket 30 is inserted into the optical connector plug 10, the main body of the optical connector plug 10 is supported by the second lock 21. That is, since the socket 30 is inserted into the optical connector plug 10 while the lever 12 is slidable, the socket 30 and the optical connector plug 10 can be connected. Further, when the socket 30 is removed from the optical connector plug 10, the lever 12 is supported by the first lock 14. That is, the lever 12 is slidable. Thereby, the socket 30 can be removed from the optical connector 10. By providing the first lock 14 and the second lock 21, it is possible to make the portion supported during insertion different from the portion supported during removal. Therefore, the optical connector plug 10 can be inserted into and removed from the socket 30 without intervention of a human hand. As a result, the socket can be inserted into and removed from the optical connector plug for the outside line without using the extension optical cable.

  By omitting the extension optical cable, the light dividing points can be reduced. Thereby, optical loss is reduced and reliability is improved. Further, since an area for processing the extra length of the optical cable is not required, it is possible to improve the function by mounting many other components, and the plug-in device can be downsized. Further, by omitting the extension optical cable, the flow of wind is improved and the cooling performance is improved, so that it is possible to increase the functionality and reduce the number of heat countermeasure members. Further, by omitting the extension optical cable, the mounting design is facilitated, the assemblability is improved, and the development period and the manufacturing period can be shortened.

  The optical connector plug 10 may be removed from the socket 30 with the printed wiring board 50 inserted into the plug-in device. Referring to FIG. 15, the first lock 14 can be unlocked by the lock receiver 22 by pressing the first lock 14 toward the lever 12. Referring to FIG. 15, if the second lock 21 is pushed up and down, the main body of the optical connector plug 20 is also unlocked. If the lever 12 is moved backward while supporting the lever 12 in this state, the optical connector plug 10 can be removed from the socket 30.

  Further, when the optical connector plug 10 is not inserted into the adapter 20, the adapter 20 is in a state where a hole is opened. Therefore, a cap may be attached to the adapter 20 from the viewpoint of wind leakage and dust prevention during forced air cooling.

  In the first embodiment, the first lock is provided on the lever of the optical connector plug, but may be provided on the adapter. FIG. 16 is an enlarged view of the vicinity of the adapter 20a according to the second embodiment. In this embodiment, the optical connector plug 10 does not include the first lock 14.

  The adapter 20a includes a socket portion 23 into which the optical connector plug 10 is inserted, a main body 25 provided with a recess 24 fitted to the internal lock 31 of the socket 30 and fixed to the socket portion 23, and a lever 26.
