Embodiments for Carrying Out the Invention

[0010] [Description of Embodiments of the Present Disclosure] First, the embodiments of the present disclosure will be listed and described. (1) The optical panel according to one aspect of the present disclosure is a base having a first end portion and a second end portion opposite to the first end portion, A first layer provided on the upper part of the base and configured to be movable with respect to the base in a first direction from the second end portion toward the first end portion and in a second direction from the first end portion toward the second end portion; A second layer provided on the upper part of the first layer, movable in the first direction and the second direction with respect to the first layer, and connected to the first layer so as to be movable together with the first layer when the first layer moves with respect to the base; A plurality of first adapters supported by the second layer and each configured such that a plurality of first optical connectors can be inserted and removed; A plurality of second adapters supported by the second layer, arranged on the second direction side of the plurality of first adapters, and each configured such that a plurality of second optical connectors can be inserted and removed, At least one of the plurality of first adapters is optically connected to one of the plurality of second adapters. According to this configuration, it is possible to provide an optical panel with high workability. Specifically, since the first layer and the second layer are movable in the first direction and the second direction, optical connection operations between the optical connectors and the optical adapters can be performed on both the first end side and the second end side, so that the workability can be improved.

[0011] (2) The optical panel according to (1) above Further includes a first locking portion that restricts the movement of the first layer with respect to the base, and A second locking portion that restricts the movement of the second layer with respect to the first layer, One of the first locking portion and the second locking portion can be operated to release the restriction of movement on the first end side, It is preferable that the other of the first locking portion and the second locking portion can be operated to release the restriction of movement on the second end side. For example, assume a case where racks storing a large number of optical panels are arranged without gaps like in a data center, and to go to the opposite side, one has to move around a large number of racks. In such a case, if there is only one layer that can move in the first direction and the second direction, and the locking portion that restricts the movement of that one layer can only be released from either the first end side or the second end side, the workability on the other side will deteriorate. However, according to the above configuration of the present disclosure, since the lock can be released on both the first end side and the second end side, it is possible to suppress the movement of the first layer and the second layer except during work without significantly degrading the workability even in a place like the above-mentioned data center.

[0012] (3) The optical panel according to (2) above, The second locking portion can release the movement restriction by applying a force of a predetermined strength or more in one of the first direction and the second direction, The first locking portion can release the movement restriction by applying a force in a direction different from the one direction, and preferably, even if a force of the predetermined strength is applied in the first direction or the second direction which is the direction opposite to the one direction, the movement restriction is not released. According to this configuration, by making the addition of a force of a predetermined strength or more in one of the first direction and the second direction a requirement for releasing the second locking portion, the workability is improved, and for releasing the first locking portion, the addition of a force in a direction different from the one direction is required, and by ensuring that the movement restriction is not released even if a force of the predetermined strength is applied in the first direction or the second direction which is the direction opposite to the one direction, for example, it is possible to suppress a situation where when trying to move only the second layer, the first locking portion is unintentionally released and the first layer moves.

[0013] (4) The optical panel according to (3) above, The number of the first adapters is larger than the number of the second adapters, The first adapter moves in the first direction to move the first layer and moves near the first end, The second locking portion can be released by applying a force equal to or greater than the predetermined strength in the second direction to the second layer. The second adapter may be configured to move to the vicinity of the second end portion by moving the second layer in the second direction. In order to move the first adapter to the vicinity of the first end portion, it is necessary to move the first layer in the first direction. Here, the possibility that the first locking portion provided for the first layer becomes unlocked unintentionally is lower than that of the second locking portion. Therefore, according to the above configuration of the present disclosure, it is possible to suppress a situation in which the first optical connector comes off from the first adapter on the side of the first adapter having a larger number than the second adapter.

[0014] (5) The optical panel according to (3) above, The number of the second adapters is larger than the number of the first adapters, The first adapter moves to the vicinity of the first end portion by moving the first layer in the first direction, The second locking portion can be released by applying a force equal to or greater than the predetermined strength in the second direction to the second layer. The second adapter may be configured to move to the vicinity of the second end portion by moving the second layer in the second direction. Since the number of the second adapters is larger than that of the first adapters, it is assumed that the number of working times and the working frequency are larger than those of the first adapter. Here, in order to move the second adapter to the vicinity of the second end portion, it is necessary to move the second layer in the second direction, but the second locking portion provided for the second layer is easier to release than the first locking portion. Therefore, according to the above configuration of the present disclosure, the workability can be further improved.

[0015] [Details of Embodiment of the Present Disclosure] Hereinafter, examples of embodiments of the optical panel according to the present disclosure will be described with reference to the drawings. In the following description, even if they are different drawings, the same or corresponding elements are given the same reference numerals or names, and duplicate descriptions are omitted as appropriate.

These directions are relative directions set for convenience of explanation. In each figure, "F" is the "front direction", "B" is the "rear direction", "L" is the "left direction", "R" is the "right direction", "U" is the "up direction", and "D" is the "down direction". In the following description, the "left and right direction" means a direction including the "left direction" and the "right direction", and the "up and down direction" means a direction including the "up direction" and the "down direction".

[0017] First, with reference to FIGS. 1 to 6, the structure of the optical panel 1 and its components according to the present embodiment will be described. FIG. 1 is a perspective view of the optical panel 1 according to an embodiment of the present disclosure. FIG. 2 is a perspective view showing the internal structure of the optical panel 1 shown in FIG. 1. Specifically, FIG. 2 shows the optical panel 1 with the top plate 60 not shown and the first opening / closing portion 51 and the second opening / closing portion 53 opened. FIG. 3 is a partial cross-sectional view of the optical panel 1 cut along the line A1-A1 shown in FIG. 2. In FIG. 3, the top plate 60 is shown. FIG. 4 is a perspective view of the base 10 according to an embodiment of the present disclosure. FIG. 5 is a perspective view of the first layer 20 according to an embodiment of the present disclosure. FIG. 6 is a perspective view of the second layer 30 according to an embodiment of the present disclosure.

[0018] FIGS. 1 to 3 show the optical panel 1 according to the present embodiment. The optical panel 1 according to the present embodiment includes, as components, the base 10 shown in FIG. 4, the first layer 20 shown in FIG. 5, the second layer 30, the first adapter 41, and the second adapter 42 shown in FIG. 6. Hereinafter, after detailing the structure of each component, the structure of the optical panel 1 will be detailed.

[0019] As shown in FIG. 4, the base 10 includes a first end portion 11, a second end portion 12, a side surface portion 13, a first locking portion 14, an upper edge portion 15, and a lead-out hole 16. The first end portion 11 is the front-side end (edge) of the base 10. The second end portion 12 is the rear-side end (edge) of the base 10. In the following description, the direction from the second end portion toward the first end portion (front direction) is also referred to as the "first direction". Also, the direction from the first end portion toward the second end portion (rear direction) is also referred to as the "second direction".

[0020] The side surface portion 13 stands upright from the respective edge sides on the left and right sides of the base 10. The upper edge portion 15 is provided so as to extend from the upper end of the side surface portion 13 in the inner direction of the base 10 on the front and rear sides of the side surface portion 13. The first locking portion 14, together with the first locking portion 22 (see FIG. 5 etc.), restricts the movement of the first layer 20 with respect to the base 10. The first locking portion 14 is a hole for piercing the first locking portion 22. The locking and unlocking by the first locking portions 14 and 22 will be described in detail in a later paragraph. The lead-out holes 16 are respectively provided on the front and rear sides of the side surface portion 13. The lead-out holes 16 are holes for leading out the cable of the optical connector to the outside of the optical panel 1 when the optical panel is in use.

[0021] As shown in FIG. 5, the first layer 20 includes a side surface portion 21, a first locking portion 22, a second locking portion 23, an upper edge portion 24, a slide plate 25, a slide hole 26, and a handle 27. The side surface portion 21 stands upright from the respective edge sides on the left and right sides of the first layer 20. The upper edge portion 24 is provided so as to extend from the upper end of the side surface portion 21 in the inner direction of the first layer 20. The slide plate 25 is connected to the upper edge portion 24 so as to be parallel to the side surface portion 21. The slide plate 25 has a slide hole 26 into which a slide pin 31 (see FIG. 6) is inserted.

[0022] The first locking portion 22, together with the first locking portion 14 shown in FIG. 4, restricts the movement of the first layer 20 with respect to the base 10. The first locking portion 22 has a structure that engages with the first locking portion 14 and is, for example, a nylon latch. The first locking portions 14 and 22 may adopt other configurations as long as they can restrict the movement of the first layer 20 with respect to the base 10.

[0023] The second locking portion 23, together with the second locking portion 32 (see FIG. 6 etc.), restricts the movement of the second layer 30 with respect to the first layer 20. The second locking portion 32 is a roller catch that catches the second locking portion 23. The second locking portion 23 may adopt other configurations as long as it can, together with the second locking portion 32, restrict the movement of the second layer 30 with respect to the first layer 20. As the second locking portion 32, for example, a catch structure such as a ball catch or a magnet catch may be adopted. Also, the first locking portions 14 and 22 and the second locking portions 23 and 32 may adopt similar structures. Note that the locking and unlocking by the second locking portions 23 and 32 will be described in detail in a later paragraph. The handle 27 is provided at the frontward-side end of the first layer 20. The handle 27 is, for example, a portion that can be gripped by the user and is provided to facilitate the operation when moving the first layer 20 with respect to the base 10.

[0024] As shown in FIG. 6, the second layer 30 has a slide pin 31, a second locking portion 32, a handle 33, and side portions 35. The side portions 35 stand upright from the respective end edges on the left and right sides of the second layer 30. The second layer 30 does not have the side portions 35 at the rearward-side end. Two slide pins 31 protruding outward in the outer direction of the second layer 30 are provided on each side portion 35. Also, the second locking portion 32 is provided on the rearward side of the side portion 35. The second locking portion 32 has a structure that is gripped by the second locking portion 23. The handle 33 is provided at the rearward-side end of the second layer 30. The handle 33 is, for example, a portion that can be gripped by the user and is provided to facilitate the operation when moving the second layer 30 with respect to the first layer 20.

[0025] Further, a plurality of first adapters 41 and a plurality of second adapters 42 are provided on the second layer 30. The numbers of the first adapters 41 and the second adapters 42 are not particularly limited and may be the same or different. In the example shown in FIG. 6, the number of the first adapters 41 is 24, and the number of the second adapters 42 is 4. Therefore, in the example shown in FIG. 6, the number of the first adapters 41 is larger than the number of the second adapters 42, but it may be configured such that the number of the second adapters 42 is larger than the number of the first adapters 41.

[0026] The first adapter 41 is an optical adapter supported by the second layer 30 and configured such that a first optical connector can be inserted and removed. The second adapter 42 is an optical adapter supported by the second layer 30 and configured such that a second optical connector can be inserted and removed. The second adapter 42 is arranged on the second direction side of the plurality of first adapters 41. In this example, the plurality of first adapters 41 and the plurality of second adapters 42 are each arranged in a row along the left-right direction, but the present invention is not limited thereto. The plurality of first adapters 41 and the plurality of second adapters 42 may be arranged, for example, in a zigzag pattern, in two or more rows in a stepped manner along the left-right direction, or arranged such that two or more rows along the left-right direction are provided in the up-down direction.

[0027] At least one of the plurality of first adapters 41 is optically connected to one of the plurality of second adapters 42. Hereinafter, the description will be made on the assumption that all of the plurality of first adapters 41 are each optically connected to any one of the plurality of second adapters 42. In each figure, the optical connection portion between the first adapter 41 and the second adapter 42 is not shown.

[0028] The first optical connector and the second optical connector are not particularly limited and may be any type of optical connector. The first optical connector and the second optical connector may be of the same type, but different types are preferred. As a preferred specific example, the second optical connector is an MPO connector, and the first optical connector is an LC connector with fewer cores than the MPO connector. In this case, the first adapter 41 becomes an LC adapter, and the second adapter 42 becomes an MPO adapter. Also, the number of the first adapters 41 is larger than the number of the second adapters 42. Also, the first optical connector may be an MPO connector, and the second optical connector may be an LC connector with fewer cores than the MPO connector. In this case, the second adapter 42 becomes an LC adapter, and the first adapter 41 becomes an MPO adapter. Also, the number of the first adapters 41 is smaller than the number of the second adapters 42. Note that the first adapter 41 and the second adapter 42 may use a plurality of types of adapters in combination. For example, as the first adapter 41 or the second adapter 42, a single-core LC adapter, a multi-core LC adapter, an MPO adapter, etc. may be used in combination. Of course, the number of the first adapters 41 may be the same as the number of the second adapters 42.

[0029] Hereinafter, the optical panel 1 will be described. As shown in FIG. 3, in the optical panel 1, the first layer 20 is provided on the upper part of the base 10. Here, the first layer 20 is configured to be movable in the first direction and the second direction with respect to the base 10. Specifically, the first layer 20 is supported by the base 10 but not fixed to the base 10 in a state where the movement is not restricted by the first locking portions 14 and 22. Therefore, the first layer 20 is movable in the first direction and the second direction with respect to the base 10. Note that the contact between the side surface portion 13 of the base 10 and the side surface portion 21 of the first layer 20 restricts the movement of the first layer 20 in the left-right direction. The contact between the upper edge portion 15 of the base 10 and the upper edge portion 24 of the first layer 20 restricts the movement of the first layer 20 in the up-down direction.

[0030] Also, as shown in FIG. 3, in the optical panel 1, the second layer 30 is provided above the first layer 20. Here, the second layer 30 is connected to the first layer 20 so as to be movable in the first direction and the second direction with respect to the first layer 20. Specifically, the slide pins 31 of the second layer 30 are inserted into the slide holes 26 extending along the first direction and the second direction in a state where they can move in the first direction and the second direction. Note that the configuration including the slide pins 31 and the slide holes 26 is an example, and other configurations may be adopted as long as the second layer 30 can move in the first direction and the second direction with respect to the first layer 20. For example, the first layer 20 and the second layer 30 may be connected by slide rails, guide grooves may be provided on the upper surface of the first layer 20, and rollers corresponding to the guide grooves may be provided on the lower surface of the second layer, or other conventionally known configurations may be adopted.

[0031] Further, the second layer 30 is configured to be movable together with the first layer 20 when the first layer 20 moves with respect to the base 10. In the optical panel 1 according to the present embodiment, the second layer 30 is placed on the first layer 20. Therefore, when the first layer 20 moves, the second layer 30 can also move together with the first layer 20. Also, the state in which the movement of the second layer 30 is restricted by the second locking portions 23 and 32 can be said to be a state in which the second layer 30 is fixed to the first layer 20. Thus, by restricting the movement of the second layer 30 by the second locking portions 23 and 32, the second layer 30 can move more integrally with the first layer 20 when the first layer 20 moves. Note that when a member for releasably fixing the second layer 30 to the first layer 20 is provided like the second locking portions 23 and 32, the second layer 30 does not have to be placed on the first layer 20.

[0032] In the optical panel 1, the optical connection portions of the first adapter 41 and the second adapter 42 are covered by a protection plate 34 (see FIGS. 2 and 3). Also, in the optical panel 1, a top plate 60 (see FIGS. 1 and 3) is connected to the upper edge portion 15 of the base 10. Further, in the optical panel 1, a mounting plate 55 (see FIGS. 1 and 2) is connected to the side surface portion 13 of the base 10. The mounting plate 55 is a member for fixing the optical panel 1 to, for example, a rack for housing the optical panel 1.

[0033] Also, as shown in FIGS. 1 to 3, the optical panel 1 includes a first opening / closing portion 51 having a third locking portion 52 and a second opening / closing portion 53 having a fourth locking portion 54. The first opening / closing portion 51 is a plate-like member connected to the first end portion 11 and rotatable about the first end portion 11. The third locking portion 52 can lock the first opening / closing portion 51 in a state where the first opening / closing portion 51 closes the space between the base 10 and the top plate 60 on the first end portion 11 side. The second opening / closing portion 53 is a plate-like member connected to the second end portion 12 and rotatable about the second end portion 12. The fourth locking portion 54 can lock the second opening / closing portion 53 in a state where the second opening / closing portion 53 closes the space between the base 10 and the top plate 60 on the second end portion 12 side. The third locking portion 52 and the fourth locking portion 54 can be locked and unlocked using corresponding keys. By providing the third locking portion 52 and the fourth locking portion 54, for example, it is possible to prevent incorrect operations by third parties.

[0034] Next, with reference to FIGS. 7 to 10, a method of using the optical panel 1 according to the present embodiment will be described. FIG. 7 is a perspective view showing a state in which the first layer 20 is moved to the first direction side in the optical panel 1 shown in FIG. 2. FIG. 8 is a partial cross-sectional view when the optical panel 1 is cut along line A2-A2 shown in FIG. 7. FIG. 9 is a perspective view showing a state in which the second layer 30 is moved to the second direction side in the optical panel 1 shown in FIG. 2. FIG. 10 is a partial cross-sectional view when the optical panel 1 is cut along line A3-A3 shown in FIG. 9. Note that the top plate 60 is not shown in FIGS. 7 and 9, but is shown in FIGS. 8 and 10.

[0035] Figures 7 and 8 show a state where the locking by the first locking portions 14 and 22 is released, and the movement of the second layer 30 relative to the first layer 20 is restricted by the second locking portions 23 and 32. In this state, the user can move the first layer 20 in the first direction and the second direction with respect to the base 10 by applying a force to the first layer 20. In the examples of Figures 7 and 8, by moving the first layer 20 to the first direction side, a plurality of first adapters 41 have moved near the first end portion 11. This facilitates the insertion and removal operation of the first connector with respect to the first adapter 41. The fact that such use is possible is particularly useful in the optical panel 1 where the space between the base 10 and the top plate 60 is narrow, such as in the case of a 1U size (height of about 44 mm).

[0036] Also, in the examples of Figures 7 and 8, by moving the first layer 20 to the first direction side, the second layer 30 has also moved to the first direction side together with the first layer 20. Due to the second layer 30 being fixed to the first layer 20 by the second locking portions 23 and 32, etc., the relative positional relationship between the first layer 20 and the second layer 30 in the example of Figure 8 is not different from that in the example of Figure 3.

[0037] Figures 9 and 10 show a state where the movement of the first layer 20 with respect to the base 10 is restricted by the first locking portions 14 and 22, and the locking by the second locking portions 23 and 32 is released. In this state, the user can move the second layer 30 in the first direction and the second direction with respect to the first layer 20 by applying a force to the second layer 30. In the examples of Figures 9 and 10, by moving the second layer 30 to the second direction side, a plurality of second adapters 42 have moved near the second end portion 12. This facilitates the insertion and removal operation of the second connector with respect to the second adapter 42. The fact that such use is possible is particularly useful in the optical panel 1 where the space between the base 10 and the top plate 60 is narrow, as described above. Since the first layer 20 is fixed to the base 10 by the first locking portions 14 and 22, the relative positional relationship between the base 10 and the first layer 20 in the example of Figure 10 is not different from that in the example of Figure 3.

[0038] Next, with reference to FIGS. 11 to 13, the first locking portions 14 and 22 and the second locking portions 23 and 32 in the optical panel 1 according to the present embodiment will be described in detail. FIG. 11 is a partial cross-sectional view when the optical panel 1 is cut along the A4-A4 line shown in FIG. 2. FIG. 12 is a perspective view showing a state in which the first locking portions 14 and 22 are released in the optical panel 1 shown in FIG. 11. FIG. 13 is a perspective view showing a state in which the second locking portions 23 and 32 are released in the optical panel 1 shown in FIG. 11.

[0039] In the example of FIG. 11, the rearward end portion of the first locking portion 22 is inserted into the first locking portion 14. This state is a state in which the first layer 20 is locked by the first locking portions 14 and 22, that is, a state in which the movement of the first layer 20 with respect to the base 10 is restricted. To release the lock, for example, a force equal to or greater than a first strength may be applied to the first locking portion 22 in the first direction. By applying a force equal to or greater than the first strength to the first locking portion 22 in the first direction, the rearward end portion of the first locking portion 22 comes out of the first locking portion 14 as shown in FIG. 12, and the restriction on the movement of the first layer 20 with respect to the base 10 is released. When locking again, the rearward end portion of the first locking portion 22 may be inserted into the first locking portion 14. Thus, the first locking portions 14 and 22 can be locked and unlocked on the first end portion 11 side.

[0040] Further, in the example of FIG. 11, the tip of the second locking portion 32 (not shown in FIG. 11) is in a state of being gripped by the second locking portion 23. This state is a state in which the second layer 30 is locked by the second locking portions 23 and 32, that is, a state in which the movement of the second layer 30 relative to the first layer 20 is restricted. To release the lock, for example, a force equal to or greater than a second strength may be applied to the second locking portion 32 in the second direction. For example, by an operation such as pulling the second layer 30 in the second direction, a force equal to or greater than a second strength is applied to the second locking portion 32 in the second direction, so that as shown in FIG. 13, the second locking portion 32 comes out of the second locking portion 23, and the restriction on the movement of the second layer 30 relative to the first layer 20 is released. When locking again, for example, by an operation such as pushing the second layer 30 in the first direction, a force equal to or greater than a predetermined strength may be applied to the second locking portion 32 in the first direction from the state where the second locking portion 32 is in contact with the second locking portion 23. Thus, the second locking portions 23 and 32 can be locked and unlocked on the second end portion 12 side.

[0041] As described above, in the optical panel 1 according to the present embodiment, the second locking portions 23 and 32 are unlocked by applying a force equal to or greater than a second strength to the second locking portion 32 in the second direction, and the first locking portions 14 and 22 are unlocked by applying a force equal to or greater than a first strength to the first locking portion 22 in the first direction. Here, the force of the first strength is greater than the force of the second strength. Therefore, in the optical panel 1 according to the present embodiment, even if a force of the second strength is applied to the first locking portion 22 in the first direction, the first locking portions 14 and 22 are not released. That is, when starting to apply a force of the same strength to the second locking portion 32 in the second direction and to the first locking portion 22 in the first direction and gradually increasing the applied force, the second locking portions 23 and 32 are released before the first locking portions 14 and 22. Thereby, for example, by applying a force equal to or greater than a second strength to the second locking portion 32 in the second direction by an operation such as pulling the second layer 30 in the second direction, the second locking portions 23 and 32 are released while the locks of the first locking portions 14 and 22 are not released.

[0042] Note that the first locking portions 14 and 22 may be configured to be unlocked by applying a force equal to or greater than a first strength to the second direction side with respect to the first locking portion 22. When configured in this way, it is preferable that the second locking portions 23 and 32 are configured to be unlocked by applying a force equal to or greater than a second strength to the first direction side with respect to the second locking portion 32.

[0043] The first locking portions 14 and 22 are preferably configured to be unlocked by applying a predetermined force in a direction different from the direction in which a force is applied to unlock the second locking portions 23 and 32 with respect to the first locking portion 22. This different direction may be the direction opposite to the direction in which a force is applied to unlock the second locking portions 23 and 32 as in the above example, or may be another direction (for example, the right direction, the left direction, the upward direction, the downward direction, etc.). Specifically, the first locking portion 14 may be a hole penetrating the side surface portion 13 in the left-right direction, and the first locking portion 22 may be a nylon latch or a pin that can be inserted into and removed from the first locking portion 14 in the left-right direction. When configured in this way, of course, even if a force equal to or greater than a second strength is applied to the first locking portion 22 in the direction opposite to the direction in which a force is applied to unlock the second locking portions 23 and 32, the lock is not released.
