Description

  The present invention relates to a dual-link optical connector holder capable of integrally holding two optical connectors used for optical communication or the like, for example.

  In recent years, optical communication has become widespread, and in a transmission system for optical communication, for example, a cord 2 with an optical connector as shown in FIG. The connection to the signal connection partner device 50 is performed.

  The cord 2 with an optical connector includes an optical connector 1 and an optical fiber cord 4. The optical connector 1 has an optical connector main body 3 having a substantially rectangular cross section as shown in FIGS. 10 and 11, for example. have. In the examples shown in these figures, the optical connector body 3 has a substantially square corner formed on a curved surface (see FIG. 10C). The optical fiber cord 4 is formed by coating the outer periphery of the optical fiber cord with a nylon resin or the like, and the optical fiber cord with the coating on the tip end side of the optical fiber cord 4 removed is inserted into the ferrule 22. It is inserted into the optical connector body 3 in a fixed state.

  The boot 5 is put on the optical fiber cord 4 pulled out from the rear end side of the optical connector main body 3 in the drawing site region on the rear end side of the optical connector main body 3. In this example, the outer diameter of the boot 5 is formed slightly larger than the diameter of the optical connector body 3. Although the length of the optical fiber cord 4 is very long, FIG. 11 and the like show a state where it is cut short.

  At the center of the upper surface of the optical connector body 3 on the proximal end side in the longitudinal direction, the proximal end side of the operation lever 6 extending diagonally forward and upward is connected, and as shown in FIG. The base end of a lock lever 7 extending obliquely upward and rearward is connected to the top surface of the distal end of the main body 3, and the distal end of the lock lever 7 is located below the distal end of the operation lever 6. In the central region of the upper surface 9 on the rear side of the optical connector main body 3, raised surfaces 8 are formed on both sides of the proximal end of the operation lever 6 from the rear proximal end of the upper surface 9 to the front. The raised surface 8 is formed as a surface higher than the other surface of the upper surface 9 of the optical connector main body 3 via a step. In this example, the raised surface 8 is formed wider than the distal end side of the operation lever 6 (see FIG. 11).

  The optical connector 1 moves the cord 2 with an optical connector toward the signal connection partner device 50 as shown by the arrow in FIG. 10A, and moves the distal end side of the connector body 3 to the signal connection partner device 50. When the optical connector 1 is inserted, the lock lever 7 goes down once and returns to the upper position again at the connection position, whereby the optical connector 1 is locked in the state of being inserted into the signal connection partner device 50, and the optical fiber cord 4 is connected to the signal connection partner. A signal is connected to the side device 50. When the inserted state is locked, the operation lever 6 is pressed down as shown by the arrow in FIG. 10B, and the lock lever 7 is pressed down in conjunction with this operation, thereby The lock is released.

  In the example shown in FIGS. 10 and 11, two pairs of optical connector-equipped cords 2 for optical transmission and optical reception are inserted and connected to the signal connection partner device 50 as a pair. For example, when performing inspection on these cords 2 with optical connectors, for example, when two cords 2 with optical connectors are detached from the signal connection partner device 50, which of the two cords 2 with optical connectors is used for optical transmission. In the cord 2 with the optical connector, it is difficult to distinguish which of the cords 2 with the optical connector for receiving light.

  In this case, when the code 2 with the optical connector is connected to the signal connection partner device 50 again after the inspection, if the transmission side and the reception side are mistaken, a trouble occurs. 2 so that the two optical connectors 1 serving as a pair for the target optical transmission and the target optical reception can be integrally held so as to distinguish which is the cord 2 with the optical connector on the receiving side. A coupling optical connector holder is used.

  In addition, although the prior art document was searched, the corresponding prior art document was not found.

  However, the conventionally used double-connecting optical connector holder requires the optical connector 1 to be held by the double-connecting optical connector holder without removing the optical connector 1 from the signal connection partner device 50. There is a problem that workability is poor. That is, the double connector optical connector holder has two optical connector holding portions arranged side by side on the left and right. For example, one optical connector 1 is connected to the left from the left side of the double connector optical connector. The optical connectors 1 are separately inserted from the left and right sides, for example, by inserting the optical connector 1 on the other side into the optical connector holding portion on the right side of the dual-connecting optical connector. Since the holders are inserted and fixed one by one, if the optical connector 1 is connected to the signal connection partner device 50 in a manner as shown in FIG. It cannot be inserted into the holding part.

  For this reason, for example, first, one optical connector 1 is detached from the signal connection partner device 50, and the optical connector 1 is separated from the left side of the dual connector optical connector to the left optical connector holder of the dual connector optical connector holder. Then, the optical connector 1 on the other side is detached from the other device 50 for signal connection, and the optical connector 1 is held from the right side of the duplex optical connector to the right side of the duplex optical connector holder. Since the work of inserting the optical connector into the unit is required, the workability is poor, and the two optical connectors 1 are integrally held in a state where the optical connector 1 is connected to the signal connection partner device 50 with a better workability. It has been desired to realize a possible double optical connector holder.
