  • Patent Document 1 discloses a configuration that allows the adapters to be removed from the patch panel. Specifically, multiple adapters 46 are fixed to a panel 60, and the panel 60 is slidable. In such patch panels, it is common to fix the adapters using a mechanism that utilizes the elastic deformation of a member, such as a snap fit.
  • connection or maintenance work is performed on a patch panel, it may be necessary to replace only some of the adapters. If the adapters are fixed using the elastic deformation of the components, it will be necessary to elastically deform the components again in order to remove the adapters. When such an elastic deformation force is applied to the adapter, a large force may be applied to the optical fiber connected to the adapter. When a large force is applied to the optical fiber, it may lead to an increase in optical connection loss or the occurrence of a break in the optical fiber.

  • the patch panel 1 of this embodiment includes a housing 2 and a plurality of adapters 3 having protrusions 3c.
  • the housing 2 includes a frame F having a right support 30A and a left support 30B spaced apart in the left-right direction Y, and capable of arranging a plurality of adapters 3 between the right support 30A and the left support 30B, a front member group 50 supported by the frame F and abutting against each of the protrusions 3c of the plurality of adapters 3, a rear member group 60 spaced apart from the front member group 50 in the front-rear direction X perpendicular to the left-right direction Y and abutting against each of the protrusions 3c of the plurality of adapters 3, and restricting members 10A, 10B, 20A, 20B that restrict the movement of at least a portion of the front member group 50 (intermediate members 52A, 52B) relative to the frame F.
  • the restricting members 10A, 10B, 20A, 20B move relative to the frame
  • the protrusion 3c of the adapter 3 is sandwiched between the front member group 50 and the rear member group 60 in the front-rear direction X. Therefore, the position of the adapter 3 in the front-rear direction X can be determined.
  • the front member group 50 becomes movable relative to the frame F. By moving the front member group 50, the positioning of the adapter 3 is released, and it becomes possible to move the adapter 3 in the front-rear direction.
  • the force applied to the adapter 3 when removing the adapter 3 can be reduced, compared to when the adapter 3 is fixed to the housing 2 by, for example, a snap fit. Therefore, it is also possible to suppress the application of a strong force to the optical fiber 3f (see FIG. 10) connected to the adapter 3.
  • each of the multiple adapters 3 has a second protrusion 3d that protrudes in the opposite direction to the protrusion 3c.
  • the protrusions 3c and second protrusions 3d of the multiple adapters 3 are sandwiched in the front-rear direction X by the front member group 50 and the rear member group 60. This configuration makes it possible to more reliably position each adapter 3 in the front-rear direction X.
  • the multiple adapters 3 also include two adapters adjacent in the up-down direction Z, which is perpendicular to both the left-right direction Y and the front-back direction X, and the protrusion 3c of one of the two adapters 3 is in contact with the second protrusion 3d of the other of the two adapters.
  • the multiple adapters 3 are arranged without any gaps in the up-down direction Z, so that the protrusions 3c, 3d are in contact with each other. This makes it possible to reduce the overall dimension of the patch panel 1 in the up-down direction Z. Therefore, the adapters 3 can be arranged with a higher density.
  • the frame F has an intermediate support 40 disposed between the right support 30A and the left support 30B, and the front member group 50 includes a plurality of right front members 50A whose both ends are supported by the right support 30A and the intermediate support 40, and a plurality of left front members 50B whose both ends are supported by the left support 30B and the intermediate support 40.
  • the dimension of the front member group 50 in the left-right direction Y can be reduced. This makes it possible to prevent a decrease in the rigidity of the front member group 50 when the dimension of the housing 2 in the left-right direction Y is large.
  • the multiple adapters 3 include 36 adapters 3 arranged in a row in the left-right direction Y, with half of the 36 adapters 3 being arranged between the right support 30A and the middle support 40, and the remaining half being arranged between the left support 30B and the middle support 40.
  • the patch panel 1 of this embodiment is capable of stably holding such a large number of adapters 3, and each adapter 3 can be easily attached and detached.
  • the multiple adapters 3 may be connectable to multiple optical connectors 4 having a total of 864 optical fibers. Alternatively, the multiple adapters 3 may be connectable to multiple optical connectors 4 having a total of 6912 optical fibers. Alternatively, the multiple adapters 3 may be connectable to multiple optical connectors 4 having a total of 10368 optical fibers. These configurations make it possible to provide a patch panel 1 that allows for high-density wiring of optical fibers.
  • the frame F in the above embodiment had an intermediate support 40.
  • the frame F does not have to have an intermediate support 40.
  • both ends of the front member group 50 in the left-right direction Y may be supported by the right support 30A and the left support 30B.
  • both ends of the rear member group 60 in the left-right direction Y may be supported by the right support 30A and the left support 30B.
  • the force applied to the adapter 3 when removing the adapter 3 can be reduced.
  • the housing 2 in the above embodiment has four regulating members 10A, 10B, 20A, and 20B, the number of regulating members may be changed.
  • the movement of the front member group 50 may be regulated by a single member that integrates the regulating members 20A and 20B.
