Further, since the outer cover member 60 is structured to be fixed with bolts, the outer cover member 60 itself needs to have sufficient rigidity against tightening of the bolts. For this purpose, the thickness of the outer cover member 60 is increased. Had to do. As a result, there is a problem in that the outer cover member 60 is increased in size.

  On the other hand, in order not to cause such a problem, a structure in which the outer cover member 60 is attached by fitting with the housing 50 without being fixed with bolts is conceivable. However, since the second optical cable C <b> 2 is inserted / removed by the re-sector pull mounting portion 44 provided on the outer cover member 60, an external force resulting from the insertion / removal is applied to the outer cover member 60. Therefore, there is a problem that the outer cover member 60 is detached from the housing 50 due to an external force resulting from the insertion / removal of the second optical cable C2.

  In that respect, in this embodiment, since the recessive pull mounting portion 44 is provided in the intermediate member 40, an external force resulting from the insertion / removal of the second optical cable C2 is not applied to the outer cover member 60. Therefore, the outer cover member 60 is prevented from being detached from the housing 50 by inserting and removing the second optical cable C2.

  Further, the thickness of the intermediate member 40 is formed to be thicker than the thickness of the outer cover member 60. Therefore, the intermediate member 40 has sufficient rigidity for tightening the bolts, and the outer cover member 60 is prevented from being enlarged by reducing the thickness of the outer cover member 60. Further, since the intermediate member 40 is fixed with bolts and the outer cover member 60 is attached to the housing 50 by fitting, the bolts are covered with the outer cover member 60. Therefore, it can suppress that the beauty | look of the information outlet 1 is impaired.

With reference to FIG. 5, the aspect in which the first optical cable C1 is accommodated in the intermediate member 40 will be described.
The work of attaching the plug C11 to the end of the cable part C12 of the first optical cable C1 is a work with high technical difficulty performed by a specialist using a specialized tool. Therefore, even if this operation fails several times, the first optical cable C1 is previously drawn out from the construction material in advance so that the first optical cable C1 is not drawn again from the construction material. Therefore, since the length of the first optical cable C1 drawn out from the construction material is long, the extra length storage portion 43 needs a structure that can store the first optical cable C1 long. On the other hand, the first optical cable C1 needs to bend the first optical cable C1 in order to accommodate the extra length. However, if the bending is smaller than the allowable minimum radius of curvature, the first optical cable C1 has a problem. Therefore, in the extra length accommodating part 43, the first optical cable C1 needs to be accommodated in a state of being bent at an allowable minimum bending radius or more, and the space for forming the extra length accommodating part 43 is limited.

  Therefore, in the present embodiment, the first guide portion 46c to the third guide portion 46e are provided in the surplus length storage portion 43, so that the cable portion C12 can be wired in the surplus length storage portion 43 a plurality of times. It is like that. Hereinafter, specific wiring of the cable portion C12 will be described.

  As shown in FIG. 5, the extra length of the cable portion C12 is accommodated in the extra length accommodating portion 43 in a state where the plug C11 of the first optical cable C1 drawn out from the first opening hole 54 of the housing 50 is connected to the recess sector 11. . Specifically, the extra length of the cable part C12 is stored as follows.

  That is, the cable portion C12 drawn from the back surface C13 of the plug C11 is wired in the space between the first inner wall portion 46a1 and the second outer wall portion 46b2. That is, the cable part C12 is wired in a substantially semicircular shape in the same space. The cable portion C12 is wired downward in the height direction from between the first inner wall portion 46a1 and the side wall portion 41 facing the first inner wall portion 46a1 in the length direction, and the second inner wall portion Wiring is performed in the space between 46a2 and the second outer wall portion 46b2. Further, the cable portion C12 drawn out from the back surface C13 of the plug C11 is once extended along the height direction by being wired between the inner straight portion 46a3 and the outer straight portion 46b3. With this configuration, it is possible to suppress a bending force from being applied to the cable portion C12 adjacent to the back surface C13 of the plug C11.

Here, when the cable part C12 straddles the first guide part 46c from the back side in the depth direction, the cable part C12 is changed to the back side in the depth direction. In this state, the cable portion C12 is wired so as to straddle the plug C11 from the back surface side in the depth direction and to the left in the length direction and upward in the height direction. And the height of the cable part C12 at the time of straddling the plug C11 by the 2nd guide part 46d can be maintained. Further, the cable portion C12 straddling the first guide portion 46c and the second guide portion 46d by the first restricting portion 46f and the second restricting portion 46g is closer to the back surface side than the end portion on the back surface side in the depth direction of the side wall portion 41. It is suppressed to move to.

The cable part C12 straddling the second guide part 46d is wired upward in the height direction and is wired so as to straddle the third guide part 46e. At this time, the cable part C12 is wired along the side wall part 41 so as to curve upward in the height direction and rightward in the length direction. Then, wiring is performed from above in the height direction of the upper projecting portion 49a, and wiring is performed so as to become lower in the height direction along the side wall portion 41 toward the right in the length direction. And cable part C12 is wired so that it may straddle from the back side of the depth direction of the 1st inner wall part 46a1. At this time, the cable portion C12 is restrained from moving to the back surface side from the end portion on the back surface side in the depth direction of the side wall portion 41 by the third restricting portion 46h and the fourth restricting portion 46i.

With reference to FIG. 6, the attachment aspect with respect to the housing 50 of the intermediate member 40 is demonstrated.

Further, the first opening hole 54 provided in the optical outlet forming portion 51 is provided in the height direction from the upper end portion in the height direction of the side wall portion 41 of the intermediate member 40 to the second outer wall portion 46b2. ing. And the 1st opening hole 54 is provided ranging to the inner surface of the side wall part 41 of the intermediate member 40 which mutually opposes in a length direction. That is, the 1st opening hole 54 is formed so that it may become the exterior rather than the cable part C12 accommodated in the surplus length accommodating part 43 (refer FIG. 5 ).

  Further, the end surface on the back surface side in the depth direction of the side wall portion 41 of the intermediate member 40 and the surface of the optical outlet forming portion 51 are in contact with each other. Thereby, it is suppressed that a space | gap arises between the side wall part 41 and the optical outlet formation part 51. FIG.

According to the information outlet 1 of the present embodiment, the following effects can be achieved.
