Further, locking holes 22a into which locking claws (not shown) provided on the back side of the plate body 40 of the decorative plate 4 described later are inserted are provided at both ends in the vertical direction of each vertical side 22 respectively. It has been. Here, the optical connector 3 includes a ferrule of a connection plug 7a attached to the front end portion of the optical fiber 7 wired in advance on the back surface side of the construction surface W1, and a connection plug connected from the front surface side of the construction surface W1. Both connection plugs are held in a state where ferrules (not shown) are aligned.

  A decorative plate 4 is attached to the front side of the plate frame 2. Hereinafter, the decorative plate 4 will be described. The decorative plate 4 is, for example, a synthetic resin molded product, and as shown in FIGS. 2, 3, and 6, a rectangular plate-like plate that is long in the left-right direction and whose outer dimensions are set to be substantially the same as the plate frame 2. It has a main body 40. The plate body 40 is provided with three vertically open windows 40a arranged in the left-right direction that expose the functional surface of the wiring device 6 attached to the attachment frames 1, 5 to the front side. Further, on the left side of the opening 40 a in the plate body 40, when the decorative plate 4 is attached to the plate frame 2, there are an optical connector 3 fixed to the plate frame 2 and a connection plug 7 a connected to the optical connector 3. A stowed part 41 to be housed is integrally provided, and a plug insertion port 41a into which a connection plug (not shown) from the surface side of the construction surface W1 is inserted is provided on the lower surface of the projecting part 41. It has been. In addition, as shown in FIG. 3, this protrusion part 41 is formed so that the protrusion amount to a front side may become large, so that it goes down.

  Next, an operation for converging the extra length of the optical fiber 7 will be described with reference to FIG. FIG. 1 shows a state in which the plate frame 2 is attached to three attachment frames 1 and 5 arranged side by side in the left-right direction, and the optical connector 3 is fixed to the fixed cylinder portion 23 of the plate frame 2. The optical fiber 7 wired in advance on the rear surface side of the construction surface W1 is led out to the front surface side of the construction surface W1 through a notch 12d provided on the lower side 12 of the mounting frame 1, A connection plug 7 a provided around the tip is wound around counterclockwise 10 a and is connected to the optical connector 3. At this time, a part of the optical fiber 7 is housed in the groove 11c provided in the right vertical side 11, and both side portions in the vertical direction are formed by the ribs 21b and 21b provided in the plate frame 2. The position is regulated. Here, in the present embodiment, an optical outlet is configured by the mounting frame 1, the plate frame 2, and the optical connector 3.

  In the present embodiment, as shown in FIG. 2, as the wiring device 6, a LAN modular jack 62 and a TEL modular jack 63 are attached to the frame portion 10 of the mounting frame 1, and two TV outlets 61 are provided. It is attached to the frame part 50 of the attachment frame 5 adjacent to the attachment frame 1. Further, a three-port power outlet 60 is attached to the frame portion 50 of the remaining mounting frame 5, and finally the outlet is provided by attaching the decorative plate 4 to the front side of the plate frame 2 fixed to the construction surface W1. The assembly of the device is completed. At this time, each wiring device 6 is in a state where its functional surface is exposed to the front side (see FIG. 2).

  Here, the mounting frame 1 according to the present invention is provided with the groove 11c that accommodates the extra length of the optical fiber 7 as described above. When the periphery of the insertion hole 12a is flat (that is, there is no step), the force from the mounting screw 8 is applied in the direction of arrow A in FIG. As a result, the force from the mounting screw 8 is applied to the entire mounting frame 1, and the thin central portion where the groove 11c is provided sinks to the inside (the back side of the construction surface W1). It becomes a state.

  By the way, in this embodiment, since the level | step difference 12c is provided in the periphery of the screw penetration hole 12a as mentioned above, in the state which attached the attachment frame 1 to the construction surface W1 using the attachment screw 8, it is opposite to the opening window 10a. Only the part on the side (the upper side in FIG. 7B) is in contact with the screw head 8a of the mounting screw 8, and the part on the opening window 10a side (the lower side in FIG. 7B) is not in contact. . As a result, the force from the mounting screw 8 is applied in the direction of the arrow B in FIG. 8B, and the sinking of the thin central portion provided with the groove 11c can be reduced.

  In the present embodiment, the screw hole 12b into which the fixing screw 9 for fixing the plate frame 2 is screwed is provided on the left side close to the optical connector 3. For example, a connection plug (not shown) is provided on the optical connector 3. 9 is applied, the load applied to the fixing screw 9 is smaller as the distance L1 from the optical connector 3 is shorter. That is, the load applied to the fixing screw 9 can be reduced by bringing the screw hole 12b into which the fixing screw 9 is screwed into the optical connector 3 as in the present embodiment. Further, by bringing the screw hole 12b closer to the optical connector 3, there is an advantage that the end of the plate frame 2 is hardly lifted.

  Thus, according to the present embodiment, the groove (concentration structure) 11c for storing the extra length of the optical fiber 7 is provided in the mounting frame 1 to which the wiring device 6 is attached. 3 may be used in parallel, and the mounting frame 1 need not be provided separately as in the conventional example, so that the overall size of the outlet device can be reduced. Further, the concentrating structure is constituted by the groove 11c provided in the vertical side 11, and it is only necessary to store the extra length of the optical fiber 7 in the groove 11c. Thus, when the groove part 11c is provided only in the vertical side 11 of one side, there exists an advantage that a wire-contraction operation | work becomes still easier. Moreover, a small frame member and an optical outlet can be provided by using the mounting frame 1 of the present embodiment.

In this embodiment, the plate frame 2 is provided with ribs (restriction portions) 21b for restricting the position of the optical fiber 7 led out from the groove portion 11c. However, as shown in FIG. The restricting portion may be constituted by the ribs 12e provided on the lateral side 12, and similarly, the optical fiber 7 can be prevented from protruding outside the plate frame 2. Further, in the present embodiment, the converging structure is configured by the groove portion 11c provided on the right vertical side 11. However, for example, as shown in FIG. 11, a plurality of ribs protruding from the front side instead of the groove portion 11c. It may constitute yield line structure 11d, the same effect as described above can be obtained. Furthermore, the restricting portion that restricts the position of the optical fiber 7 may also be configured by a plurality of ribs 12f that protrude from the front side as shown in FIG. Moreover, as shown in FIG. 11, you may provide the some rib 11e protruded in the front side so that the optical fiber 7 arrange | positioned along the rib 11d may not protrude outside the attachment frame 1. As shown in FIG. Furthermore, in the present embodiment, the two mounting frames 5 are arranged side by side with the mounting frame 1, but since the mounting frame 1 only needs to be provided, the mounting frame 5 may not be provided. One or three or more may be provided.
