The length of the optical fiber core C to be exposed may be arbitrarily determined.

  The optical splitter S is an optical component that divides and outputs an optical signal by 32 branches. An insertion port Sa into which an optical connector is inserted is provided at one end (this is the rear end) of the optical splitter S, and 32 optical fibers that transmit branched optical signals are provided at the other end (front end). A core C is attached. In FIG. 1, eight optical fiber cores C are shown as one line for easy drawing.

  The socket housing box 2 is a housing for housing an output socket (optical socket) 40 described later. The socket housing box 2 includes a lower housing 10, an upper housing 20, and a fixing portion 30, and has a substantially rectangular parallelepiped shape as a whole. The length, width and height of the socket housing box 2 are 80 mm, 39.5 mm and 29.1 mm, respectively. But the magnitude | size of the socket storage box 2 is not limited to this.

  The lower housing 10 has a substantially rectangular parallelepiped shape. One end of the lower housing 10 in the longitudinal direction (hereinafter referred to as “rear end”) protrudes upward to form a convex portion 11, so that the cross section along the longitudinal direction of the lower housing 10 is L-shaped. It has a shape. A space (internal space) for accommodating the output socket 40 is formed in the lower housing 10. The front end surface 10b of the lower housing 10, the vicinity of the front end portion of the upper surface 10c continuous with the front end surface 10b (see FIG. 4), and the front end surface of the convex portion 11 are open.

  On both side surfaces 10d of the lower housing 10, there are substantially semicircular fixing portions 30 formed with screw holes 31 along the vertical direction of the lower housing 10, near the front end portion and the rear end portion of the lower housing 10. Are provided to be continuous with the bottom surface of the lower housing 10.

A rod-like member 13 extending along the width direction is attached to the front end portion of the upper surface 11a of the convex portion 11.

  As shown in FIG. 5, four optical sockets (hereinafter referred to as “output sockets”) 40 for inserting and fixing an optical connector are located near the front end of the internal space of the lower housing 10. 10 are housed side by side in the width direction. At this time, the output socket 40 is attached so that the front end face 40b thereof substantially coincides with the front end face 10b of the lower housing 10. Therefore, when viewed from above the lower housing 10, the output socket 40 is exposed from the lower housing 10.

  The configuration of the output socket 40 will be described with reference to FIG. The four output sockets 40 accommodated in the lower housing 10 are integrated. Each output socket has a substantially rectangular parallelepiped shape, and an insertion port 41 for inserting an optical connector is formed on the front end face 40b. 1 to 5, the insertion port 41 of the output socket 40 is covered with a cap 49, but when the optical connector is inserted into the output socket 40, the cap 49 is removed. On the lower surface 40c of two of the four output sockets 40 positioned on the outside, a hook portion 42 for attaching the output socket 40 to the lower housing 10 so as to be rotatable, a protrusion 43, A claw portion 44 for fixing the output socket 40 to the lower housing 10 is provided.

  The hook portion 42 is provided near the rear end portion of the lower surface 40 c of the output socket 40. The hook portion 42 extends in the width direction of the output socket 40, and its cross section has a C-shape that opens downward (upward in FIG. 6). The protruding portion 43 is provided behind the hook portion 42 and extends in the width direction of the output socket 40. The height of the protruding portion 43 is smaller than the height of the hook portion 42. The claw portion 44 is provided in front of the center portion of the lower surface 40 c of the output socket 40. The claw portion 44 extends in the width direction of the output socket 40 and is formed to be bent in an L shape toward the front of the output socket 40.

  The four output sockets 40 are connected to the lower casing 10 by engaging hook members 42 with rod-like members (not shown) provided on the floor surface of the lower casing 10 along the width direction thereof. It is attached to be rotatable. However, since the protrusion 43 is provided, its rotation is limited to a certain range. In addition, the four output sockets 40 are configured such that a claw portion (not shown) having an inverted L-shaped cross section provided on the floor surface of the lower housing 10 and a claw portion 44 engage with each other. Fixed to.

  The upper housing 20 has a substantially rectangular parallelepiped shape, and is provided so as to contact the upper surface 10 c of the lower housing 10 and the front end surface of the convex portion 11. A hook 21 is attached to the rear end portion of the upper surface 20a of the upper housing 20. The hook 21 extends in the width direction of the upper housing 20, and the cross section has a C-shape opening downward. The upper housing 20 and the lower housing 10 are connected by engaging the hook 21 and the above-described rod-shaped member 13, whereby the upper housing 20 is connected to the lower housing 10 and the fixing portion 30. And is pivotally attached.

  The upper surface 20a of the upper housing 20 is continuous with the upper surface 11a of the convex portion 11 in the vicinity of the rear end portion, but rises with respect to the rear end portion at the center portion and the front end portion in the longitudinal direction. The front end surface 20 b of the upper housing 20 is located behind the front end surface 10 b of the lower housing 10. As a result, when the socket housing box 2 is viewed from above the upper housing 20, the plurality of output sockets 40 housed in the lower housing 10 protrude outward (forward) from the upper housing 20.

  A space (internal space) for accommodating the output socket 40 is formed in the upper housing 20. The front end surface 20b of the upper housing 20, the vicinity of the front end portion of the upper surface 20a continuous with the front end surface 20b, and the rear end surface are open. Therefore, the front end surface of the convex portion and the rear end surface of the upper housing 20 are in communication.

  Four output sockets 40 are housed side by side in the width direction of the upper housing 20 near the front end of the internal space of the upper housing 20. At this time, the output socket 40 is attached so that the front end face 40b thereof substantially coincides with the front end face 20b of the upper housing 20. Therefore, when viewed from above the upper housing 20, the output socket 40 is exposed from the upper housing 20. The four output sockets 40 housed in the upper housing 20 are integrated, and the configuration is the same as that housed in the lower housing 10 (see FIG. 6). The method for attaching the output socket 40 to the upper housing 20 is the same as the method for attaching the lower housing 10.

  The optical fiber core C entering the lower housing 10 through the guide port 12 is connected to the rear end portion 40 a of the output socket 40. The optical fiber core C connected to the output socket 40 in the lower housing 10 is accommodated in the lower housing 10 as shown in FIG. 5, for example. The optical fiber C connected to the output socket 40 in the upper housing 20 enters the upper housing 20 from the lower housing 10 through the front end surface of the convex portion 11 and the rear end surface of the upper housing 20. .

  As described above, according to the present embodiment, the housing for accommodating the output socket 40 is arranged in two upper and lower stages, so that the area required for attachment can be reduced. Moreover, since the optical splitter S is taken out of the socket housing box 2, the socket housing box 2 can be reduced in size and the optical splitter S and the socket housing box 2 can be flexibly arranged in the wiring board. Further, since the output socket 40 is attached so that the insertion port 41 of the output socket 40 approaches or separates from the fixing portion 30, the insertion port 41 is separated from the fixing portion 30 (insertion port). The optical connector can be attached to and detached from the output socket 40 in a state where 41 is moved upward, and the optical connector can be easily attached to and detached from the splitter module 1. Therefore, the splitter module 1 can be downsized and handled easily.

  In particular, in this embodiment, since the output socket 40 accommodated in the lower housing 10 is rotatably attached to the lower housing 10, the insertion port 41 of the output socket 40 is moved upward. Thus, the optical connector can be attached and detached (see FIG. 4). Moreover, since the upper housing | casing 20 is attached with respect to the lower housing | casing 10 so that rotation is possible, the insertion port 41 of the output socket 40 accommodated in it is moved upwards by rotating the upper housing | casing 20. Thus, the optical connector can be attached and detached (see FIG. 4). Further, since the output socket 40 accommodated in the upper housing 20 can be rotated with respect to the upper housing 20, the optical connector can be connected to the output socket 40 without rotating the upper housing 20. Can be easily attached and detached.

  Further, according to the present embodiment, since the upper portions of the output sockets 40 accommodated in the lower casing 10 and the upper casing 20 are exposed from these casings, the output socket 40 can be directly output from above the socket accommodating box 2. The socket 40 can be handled.

  Further, according to the present embodiment, the output socket 40 accommodated in the lower housing 10 is not covered with the upper housing 20, so that the output socket 40 in the lower housing 10 is not moved without moving the upper housing 20. Can be handled more easily.

  The present invention has been described in detail based on the embodiments. However, the present invention is not limited to the above embodiment. The present invention can be modified in various ways as described below without departing from the scope of the invention.

  In the above embodiment, the upper housing 20 is attached to the lower housing 10 so as to be rotatable, and the output socket 40 in the upper housing 20 is attached to the upper housing 20 so as to be rotatable. Only one of them may be adopted. For example, if the upper housing is pivotably attached to the lower housing, the output socket in the upper housing may be completely fixed to the upper housing.

  When the upper casing is attached to the lower casing so as to be rotatable, fixing means for maintaining the state in which the upper casing is inclined with respect to the lower casing may be provided in the storage box. In this case, since the inclined state of the housing can be maintained, the optical connector can be attached and detached more easily.

  Further, the splitter module may be configured to rotate the lower housing. For example, if the lower case is pivotably attached to a fixed part having a pedestal whose upper surface has the same shape as the lower surface of the lower case, light can be moved by moving the insertion port of the output socket in the lower case upward. The connector can be easily attached and detached.

  In the above embodiment, the four output sockets 40 are integrated, but in addition to this, the width of the splitter module may be made shorter by removing the inner wall of each socket. Needless to say, the output sockets may not be integrated, and the elements corresponding to the hook portion 42, the protrusion 43, and the claw portion 44 may be attached to each output socket.

  The means for pivotally attaching the output socket to the upper housing or the lower housing is not limited to the hook portion 42 described above. For example, an output socket 40p having a cylindrical shaft member 45 protruding in the width direction may be used (see FIG. 7), or an output socket having a cylindrical shaft hole 46 formed in the width direction. 40q may be used (see FIG. 8). When the output socket 40p is used, a shaft hole for inserting the shaft member 45 into the inner wall corresponding to the side surface of the housing may be provided. When the output socket 40q is used, the shaft hole 46 is provided. What is necessary is just to provide the shaft member to insert in the inner wall.

  When the output socket is pivotally attached to the upper or lower housing, the splitter module (container box) is provided with fixing means for maintaining the output socket inclined with respect to the housing. May be. In this case, since the inclined state of the output socket can be maintained, the optical connector can be more easily attached and detached.

  In the above embodiment, the four socket housing boxes 2 that house eight output sockets 40 and the 32-branch optical splitter S are used. However, the number of output sockets housed in the housing box and the number of housing boxes to be used The number or the type of the optical splitter is not limited to this. For example, a splitter module may be configured by combining a storage box similar to the socket storage box 2 and an 8-branch optical splitter. In addition, a splitter module is configured by combining one storage box 2a (see FIG. 9A) in which 16 output sockets are arranged in the lower housing and the upper housing with a 32-branch optical splitter. Also good. In the storage box 2a, the upper housing is composed of four housings that house four output sockets, and each housing can be rotated independently (see FIG. 9B).

  In the above embodiment, the plurality of output sockets 40 housed in the lower housing 10 are projected forward from the upper housing 20, but whether or not to make such a projection is arbitrary. Moreover, in the said embodiment, although a part of upper surface 10c of the lower housing | casing 10 and a part of upper surface 20a of the upper housing | casing 20 were opened, it is arbitrary whether the upper surface of a housing | casing is opened.

  In order to further reduce the installation area of the storage box, the corner of the rear end of the storage box may be chamfered to be a curved surface. Thereby, a possibility that an optical fiber cord, an optical cable, etc. may be caught in the corner of a storage box and disconnected may be reduced.

  In the said embodiment, although the socket accommodation box 2 accommodated the optical socket, it may replace with an optical socket and may accommodate an optical adapter. For example, the present invention can be applied to a splitter module (accommodating box) that accommodates an optical adapter fitted to an SC connector or the like.
