  Next, embodiments of the present invention will be described in detail with reference to the drawings.

<First Embodiment>
FIG. 2 is a perspective view of the optical communication device 100 according to the first embodiment of the present invention with the cover portion attached.

  The optical communication device 100 includes a housing 101 and a cover unit 102.

  The housing 101 contains an electric board 40 having a connector 41. The connector 41 is connected to the optical fiber cable 32. The optical fiber cable 32 connected to the connector 41 appears outside the optical communication device 100 from the outlet 5.

  The cover portion 102 prevents the portion where the optical fiber cable 32 is connected to the connector 41 from being exposed to the external appearance of the optical communication device 100.

  FIG. 1 is an exploded perspective view of the optical communication device 100 according to the first embodiment of the present invention with a cover portion removed.

  The housing 101 is a grip formed integrally with the housing 101 between the connector 41 attached to the electric substrate 40 and the outlet 5 where the optical fiber cable 32 connected to the connector 41 appears outside the optical communication device 100. Part 112 is provided. And the holding part 112 has elasticity.

  The casing 101 has five rails 21 and a receiving portion 23 on the surface in contact with the cover portion 102. The rail 21 slides the cover portion 102 toward the connector 41 in a direction parallel to the optical fiber cable 32 and is fitted to the housing 101. The shape and number of rails are not limited to FIGS.

  The cover portion 102 includes five hooks 22, a protrusion 24, and a protrusion 114 on the inner surface. The hook 22 is fitted while holding the rail 21 of the housing 101 in the vertical direction when sliding. The protrusion 114 comes into contact with the grip portion 112 of the housing 101 when the housing 101 and the cover portion 102 are slid and fitted. As a result, the grip portion 112 holds the optical fiber cable 32. Further, the protrusion 24 is fitted with the receiving port 23 of the housing 101.

  FIG. 3 is a cross-sectional view of the optical communication device 100 according to the first embodiment of the present invention as viewed from the direction of the outlet 5. FIG. 4 is a cross-sectional view of the optical communication device 100 according to the first embodiment of the present invention when viewed from the side surface with the outlet facing right. The protrusion 114 does not contact the grip portion 112 of the housing 101 before the cover portion 102 is slid to fit with the housing 101. However, the protrusion 114 comes into contact with the grip 112 of the housing 101 as shown in FIGS. 3 and 4 by sliding. Then, at the position where the cover portion 102 is fitted and fixed to the housing 101, the protrusion 114 comes into contact with the grip portion 112 of the housing 101. Then, as shown in FIG. 3, the elastic gripping portion 112 is deformed by the contact of the projection 114 of the cover portion 102. As the grip portion 112 is deformed, the distance between the grip portion 112 of the housing 101 and the floor 115 is reduced. Thereby, the optical fiber cable 32 passing between them is clamped.

  As described above, the first embodiment has an effect that the connection portion between the optical fiber cable and the connector is not exposed while further reducing the cost required for fixing the optical fiber cable to the optical communication device.

  The reason is that the optical communication device 100 according to the present embodiment is configured so that the grip portion 112 integrally formed with the housing 101 and the protrusion 114 of the cover portion 102 come into contact with each other to sandwich the optical fiber cable 32. This is because it is not necessary to use a dedicated part for fixing to 100.

  Furthermore, as shown in FIG. 2, in the optical communication device 100 with the cover portion 102 attached, the connection portion between the connector 41 and the optical fiber cable 32 is not exposed.

<Second Embodiment>
Next, a second embodiment based on the optical communication apparatus 100 according to the first embodiment described above will be described.

  FIG. 5 is an exploded perspective view of the optical communication apparatus 1000 according to the second embodiment of the present invention with the cover portion removed. Parts similar to those of the optical communication apparatus 100 described above are denoted by the same reference numerals, and description thereof is omitted. However, the configuration shown in FIG. 5 is an example, and the present invention is not limited to the optical communication apparatus shown in FIG.

  The optical communication device 1000 includes a housing 1 and a cover unit 2.

  The casing 1 is integrally formed with the casing 1 as shown in FIG. 5 between the connector 41 attached to the electric board 40 and the outlet 5 from which the optical fiber cable 32 appears outside the optical communication device. The two sheets have a pair of plate-like protrusions 11 and 12. At least one of the plate-like protrusions 11 and 12 has elasticity.

  FIG. 6 is a view for explaining plate-like protrusions of the optical communication apparatus 1000 according to the second embodiment of the present invention. In FIG. 6, the plate-like protrusion 12 has elasticity. The plate-like protrusion 12 is another example of the grip portion 112 of the first embodiment.

  The cover unit 2 includes a hook 22 and protrusions 13 and 14. The protrusions 13 and 14 are other examples of the protrusion 114 of the first embodiment. The projections 13 and 14 sandwich the two plate-like projections 11 and 12 of the housing 1 as the cover portion 2 slides and fits along the rail 21.

  A method for fixing the optical fiber cable 32 to the optical communication apparatus 1000 will be described.

  The optical fiber cable 32 is connected to a connector 41 attached to the electric board 40 as in FIG. The housing 1 passes the optical fiber cable 32 between the plate-like protrusions 11 and 12.

  The cover portion 2 is fitted to the housing 1 by the hook 22 by sliding in the direction of the connector 41 along the rail 21 of the housing 1 from the direction of the outlet 5.

  FIG. 7 is a diagram illustrating a state before the cover portion 2 is fitted in the optical communication apparatus 1000 according to the second embodiment of the present invention. FIG. 8 is a diagram illustrating a state in which the cover portion 2 is fitted in the optical communication apparatus according to the second embodiment of the present invention. FIG. 9 is a diagram illustrating the state of the plate-like protrusions 11 and 12 and the protrusions 13 and 14 when the cover portion 2 is fitted in the optical communication apparatus according to the second embodiment of the present invention.

  In a state before being fitted to the housing 1, the protrusions 13 and 14 do not contact the two plate-like protrusions 11 and 12 of the housing 1 as shown in FIG. 7. However, the plate-like protrusions 11 and 12 and the protrusions 13 and 14 gradually come into contact with each other by sliding from the direction of the outlet 5 in order to fit the cover portion 2 to the housing 1. As shown in FIG. 8, the projections 13 and 14 abut the plate-like projections 11 and 12 at a position where the housing 1 and the cover portion 2 are fitted. At least one of the plate-like protrusions 11 and 12 of the housing 1 has elasticity. For example, when the plate-like protrusion 12 has elasticity, the plate-like protrusion 12 is deformed inward while being in contact with the protrusion 14 of the cover portion 2 as shown in FIG. As a result, the optical fiber cable 32 is held between the plate-like protrusions 11 and 12 of the housing 1. And the optical communication apparatus 1000 can prevent the optical fiber cable 32 from coming off.

  FIG. 10 is a diagram for explaining a modification of the plate-like protrusion of the optical communication apparatus 1000 according to the second embodiment of the present invention. Two plate-like protrusions 11A and 12 shown in FIG. 10 have elasticity. In this case, when the cover part 2 is fitted, the plate-like protrusions 11A and 12 are deformed so as to sandwich the optical fiber cable 32. As a result, the optical communication device 1001 sandwiches the optical fiber cable 32 by deforming not only one of the plate-like protrusions (the plate-like protrusion 11 or 12) but also both the plate-like protrusions (11A and 12).

  As described above, the second embodiment has an effect that the holding force of the optical fiber cable can be easily adjusted.

  The reason is that the optical communication apparatus 1000 according to the present embodiment determines the holding force of the optical fiber cable according to the distance between the plate-like protrusions 11 and 12 and the protrusions 13 and 14, the thickness of each, and the like.
