Hereinafter, the first embodiment of the present invention will be described in detail with reference to the accompanying drawings. In the description of the drawings, the same or equivalent components are denoted by the same reference numerals, and the description thereof will not be repeated.

1 to 3 are perspective views of the spectroscope module of the first embodiment. Figure 4 is a plan view showing the lower frame shown in Figure 1. Fig. 5 is a perspective view of the output socket (optical socket) shown in Fig. 1 as viewed from below.

The spectroscope module 1 includes a lower casing 10, an upper casing 20, and a fixing portion 30, and has a substantially rectangular parallelepiped shape as a whole. The length, width and height of the beam splitter module 1 are 100 mm, 39.5 mm, and 29.1 mm, respectively. Of course, the size of the splitter module 1 is not limited to this.

The lower frame 10 has a substantially rectangular parallelepiped shape. One end portion (hereinafter referred to as "rear end portion") in the longitudinal direction of the lower casing 10 protrudes upward and forms the convex portion 11, so that the cross section along the longitudinal direction of the lower casing 10 is L-shaped. Inside the lower casing 10, a spectroscope S to be described later and a space (internal space) for accommodating the optical receptacles 12 and 40 are formed. The front end surface 10b of the lower casing 10 is continuous in the vicinity of the end portion before the front surface 10c of the front end surface 10b (see FIG. 3) and the front end surface of the convex portion 11 is open. On both side faces 10d of the lower casing 10, in the vicinity of the front end portion and the rear end portion of the lower casing 10, a substantially semicircular fixing portion 30 formed along the screw hole 31 in the upper and lower directions of the lower casing 10 is formed. It is continuous with the bottom surface of the lower frame 10. At the end portion of the upper surface 11a of the convex portion 11, a rod-like member 13 extending in the width direction is attached.

At the end surface 10a of the lower casing 10, an end portion (insertion port) (see FIG. 2) is inserted after the optical receptacle (hereinafter also referred to as "input socket") 12 for inserting and fixing the optical connector. The input socket 12 has a substantially rectangular parallelepiped shape. In Figs. 2 and 4, the insertion port of the input socket 12 is covered by the cover 12a. However, when the optical connector is inserted into the input socket 12, the cover 12a needs to be removed.

The configuration in the internal space of the lower casing 10 will be described with reference to Fig. 4 . The input socket 12 is housed along an inner wall corresponding to one side surface 10d of the lower casing 10. Further, the optical splitter S that outputs the optical signal in a divided manner by eight equal parts is accommodated along the inner wall corresponding to the other side surface 10d of the lower casing 10 so as to face the input socket 12. In addition, four optical sockets (hereinafter also referred to as "output sockets") 40 for inserting and fixing the optical connectors are arranged in the width direction of the lower casing 10 in the vicinity of the front end portion of the internal space. At this time, the output socket 40 is attached such that the front end surface 40b substantially coincides with the front end surface 10b of the lower casing 10. Therefore, when viewed from above the lower casing 10, the output socket 40 is exposed by the lower casing 10.

The configuration of the output socket 40 will be described with reference to Fig. 5 . The four output sockets 40 accommodated in the lower casing 10 are integrated. Each of the output sockets 40 has a substantially rectangular parallelepiped shape, and an insertion port 41 for inserting an optical connector is formed on the front end surface 40b. In FIGS. 1 to 4, the insertion port 41 of the output socket 40 is covered by the cover 49. However, when the optical connector is inserted into the output socket 40, the cover 49 needs to be removed. The four output sockets 40 are The lower surface 40c of the two output sockets located outside is provided with a hook portion 42 for mounting the output socket 40 so as to be rotatable relative to the lower housing 10, a protruding portion 43, and the output socket 40 is fixed to The lower frame 10 is used for the claw portion 44.

The hook portion 42 is provided near the end portion of the lower surface 40c of the output socket 40. The hook portion 42 extends in the width direction of the output socket 40, and has a C-shaped cross section that is opened downward (upward in FIG. 5). 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 protrusion 43 is smaller than the height of the hook 42. The claw portion 44 is provided forward of the center portion of the lower surface 40c of the output socket 40. The claw portion 44 extends in the width direction of the output socket 40, and is bent in the L shape in front of the output socket 40.

The four output sockets 40 are attached to be rotatable relative to the lower casing 10 when the rod-shaped members (not shown) provided on the bed surface of the lower casing 10 along the width direction thereof are engaged with the hook portions 42. . Of course, since the projections 43 are provided, the rotation thereof is restricted to a certain range. Further, the four output sockets 40 are fixed to the lower casing 10 when the claws (not shown) having the inverted L-shaped cross section provided on the bed surface of the lower casing 10 are engaged with the claw portions 44.

The upper housing 20 has a substantially rectangular parallelepiped shape and is provided to be in contact with the upper surface 10c of the lower housing 10 and the front end surface of the convex portion 11. A hook portion 21 is attached to the rear end portion of the upper surface 20a of the upper casing 20. The hook portion 21 extends in the width direction of the upper frame 20 and has a C-shaped cross section that opens downward. The upper housing 20 and the lower housing 10 are connected by the engagement of the hook portion 21 and the rod member 13 , whereby the upper housing 20 is attached to the lower housing 10 and the fixing portion 30 . Turn.

The upper surface 20a of the upper casing 20 is continuous with the upper surface 11a of the convex portion 11 in the vicinity of the rear end portion, but is bulged toward the rear end portion at the central portion and the front end portion in the longitudinal direction. The front end surface 20b of the upper casing 20 is located rearward of the front end surface 10b of the lower casing 10. As a result, when the spectroscope module 1 is viewed from above the upper housing 20, the plurality of output sockets 40 housed in the lower housing 10 protrude outward (front) from the upper housing 20.

A space (internal space) for housing the output socket 40 is formed inside the upper housing 20. The front end surface 20b of the upper casing 20 is continuous with the vicinity of the end portion before the upper surface 20a of the front end surface 20b, and the rear end surface is open. Therefore, the front end surface of the convex portion communicates with the rear end surface of the upper frame body 20.

In the vicinity of the end portion of the inner space of the upper casing 20, four output sockets 40 are accommodated in the width direction of the upper casing 20. At this time, the output socket 40 is attached such that the front end surface 40b substantially coincides with the front end surface 20b of the upper housing 20. Therefore, when viewed from above the upper housing 20, the output receptacle 40 is exposed by the upper housing 20. The four output sockets 40 accommodated in the upper housing 20 are integrated, and the configuration is the same as that in the case of the lower housing 10 (see FIG. 5). Moreover, the mounting method of the output socket 40 for the upper housing 20 is also the same as the mounting method for the lower housing 10.

One end of the input socket 12 and the beam splitter S is connected by the optical fiber core C1. At the other end of the spectroscope S, eight optical fiber core wires C2 are mounted, whereby the optical fiber core wire C2 connects the optical splitter S to the rear end portion 40a of the output receptacle 40. The optical fiber core wire C2 connected to the output socket 40 in the lower casing 10 is housed in the lower casing 10, for example, as shown in Fig. 4 . The optical fiber core wire C2 connected to the output socket 40 in the upper housing 20 passes through the front end surface of the convex portion 11 and the rear end surface of the upper housing 20, and enters the upper housing 20 from the lower housing 10.

As described above, according to the present embodiment, the casing for accommodating the output socket 40 is disposed in two stages, so that the area required for mounting can be reduced. In addition, the output socket 40 is attached so that the insertion port of the output socket 40 is close to or away from the fixing portion 30. Therefore, the insertion port 41 is separated from the fixing portion 30 (the insertion port 41 is moved upward). The optical connector can be attached to and detached from the output socket 40, and the optical connector of the optical splitter module 1 can be easily attached and detached. Therefore, the size of the spectroscope module 1 can be reduced, making handling easier.

In particular, in the present embodiment, the output socket 40 accommodated in the lower casing 10 is rotatably attached to the lower casing 10, so that the insertion port 41 of the output socket 40 can be moved upward to detach the light. Connector (refer to Figure 3). Further, since the upper housing 20 is attached to be rotatable relative to the lower housing 10, when the upper housing 20 is rotated, the insertion opening 41 of the output receptacle 40 accommodated therein can be moved upward to attach and detach the optical connector (refer to image 3). Moreover, since the output socket 40 accommodated in the upper housing 20 can be rotated with respect to the upper housing 20, it is not necessary to rotate the upper housing 20, and the optical connector can be easily attached or detached to the output socket 40.

Further, according to the present embodiment, the upper portion of the output socket 40 accommodated in the lower casing 10 and the upper casing 20 is exposed by the casings, so that the output socket 40 can be directly processed by the upper portion of the beam splitter module 1.

Moreover, according to the present embodiment, the output socket 40 accommodated in the lower casing 10 is not covered by the upper casing 20, so that it is not necessary to move the upper casing 20, and the output socket in the lower casing 10 can be handled more easily. 40.

Hereinabove, the present invention has been described in detail based on the embodiment thereof, but the present invention is not limited to the above embodiment. The present invention can be modified as described below without departing from the gist of the invention.

In the above embodiment, the upper housing 20 is mounted to be rotatable relative to the lower housing 10, and the output receptacle 40 in the upper housing 20 is mounted to be rotatable relative to the upper housing 20, but only Use either of these methods. For example, if the upper housing is attached to be rotatable relative to the lower housing, the output socket in the upper housing can be completely fixed to the upper housing.

When the upper housing is attached to be rotatable relative to the lower housing, the optical splitter module may be provided with a fixing mechanism for maintaining the upper housing in a state of being inclined to the lower housing. In this case, the tilting state of the frame can be maintained, so that the optical connector can be attached and detached more easily.

Further, the splitter module may be configured to rotate the lower casing. For example, if the lower frame is rotatably attached to the fixing portion including the pedestal portion having the upper surface and the lower surface of the lower casing, the insertion opening of the output socket in the lower casing can be moved upward. It is easy to load and unload the optical connector.

In the above embodiment, the four output sockets 40 are integrated, but the width of the beam splitter module can be further shortened by removing the inner walls of the respective sockets. Needless to say, the elements corresponding to the hook portion 42, the projection portion 43, and the claw portion 44 may be attached to the respective output sockets without integrating the output sockets.

The mechanism for rotatably attaching the output socket to the upper housing or the lower housing is not limited to the above-described hook portion 42. For example, an output socket 40p (see FIG. 6) including a cylindrical shaft member 45 protruding in the width direction may be used, or an output socket 40q including a cylindrical shaft hole 46 formed in the width direction may be used. (Refer to Figure 7). In the case of using the output socket 40p, it is only necessary to provide a shaft hole for inserting the shaft member 45 on the inner wall corresponding to the side surface of the frame body, or in the case of using the output socket 40q, as long as the insertion shaft is provided on the inner wall thereof. The shaft member for the hole 46 may be used.

In the case where the output socket is rotatably attached to the upper housing or the lower housing, the optical splitter module may be provided with a fixing mechanism for maintaining the output receptacle in a state in which the housing is tilted. In this case, the tilt state of the output socket can be maintained, so that the optical connector can be attached and detached more easily.

In the above embodiment, four output sockets 40 are arranged in the width direction of the spectroscope module 1, but the number of output sockets arranged is not limited to this. For example, as shown in FIGS. 8(a) and 8(b), a splitter module 1a in which 16 output sockets are arranged in each of the lower casing and the upper casing may be used. In the spectroscope module 1a, the upper frame system is constituted by four housings for accommodating four output sockets, and each of the housings is independently rotatable (see FIG. 8(b)).

In the above-described embodiment, the plurality of output sockets 40 accommodated in the lower casing 10 protrude further forward than the upper casing 20, but whether or not they are so protruded can be arbitrarily determined. Further, in the above embodiment, one of the upper surface 10c of the lower casing 10 and one of the upper surfaces 20a of the upper casing 20 are partially opened. However, whether or not the upper surface of the casing is opened can be arbitrarily determined.

Moreover, in order to further reduce the installation area of the beam splitter module, the corners of the rear end of the beam splitter module may be chamfered to form a curved surface. Thereby, it is possible to reduce the occurrence of disconnection of the optical fiber cord or the optical cable, etc., which is caught by the corner of the optical splitter module.

In the above embodiment, the optical splitter module 1 accommodates the optical receptacle instead of the optical receptacle. For example, the present invention can be applied to a spectroscope module that houses an optical adapter that is fitted with an SC connector or the like.

A space (internal space) for housing the output socket 40 is formed inside the upper housing 20. The front end surface 20b of the upper casing 20 is continuous with the vicinity of the end portion before the upper surface 20a of the front end surface 20b, and the rear end surface is open. Therefore, the front end surface of the convex portion communicates with the rear end surface of the upper frame body 20.

In the vicinity of the end portion of the inner space of the upper casing 20, four output sockets 40 are accommodated in the width direction of the upper casing 20. At this time, the output socket 40 is attached such that the front end surface 40b substantially coincides with the front end surface 20b of the upper housing 20. Therefore, when viewed from above the upper housing 20, the output receptacle 40 is exposed by the upper housing 20. The four output sockets 40 accommodated in the upper housing 20 are integrated, and the configuration is the same as that in the case of the lower housing 10 (see FIG. 14). Moreover, the mounting method of the output socket 40 for the upper housing 20 is also the same as the mounting method for the lower housing 10.

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

As described above, according to the present embodiment, the casing for accommodating the output socket 40 is disposed in two stages, so that the area required for mounting can be reduced. Further, since the spectroscope S protrudes outside the socket accommodating case 2, the socket accommodating case 2 can be miniaturized, and the spectroscope S and the socket accommodating case 2 can be elastically disposed in the distribution frame. In addition, 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. Therefore, the insertion port 41 is separated from the fixing portion 30 (the insertion port 41 is moved upward). In the state), the optical connector can be attached to and detached from the output socket 40, and the optical connector of the optical splitter module 1 can be easily attached and detached. Therefore, the size of the spectroscope module 1 can be reduced, making handling easier.

In particular, in the present embodiment, the output socket 40 accommodated in the lower casing 10 is rotatably attached to the lower casing 10, so that the insertion port 41 of the output socket 40 can be moved upward to detach the light. Connector (refer to Figure 12). Further, since the upper housing 20 is attached to be rotatable relative to the lower housing 10, when the upper housing 20 is rotated, the insertion opening 41 of the output receptacle 40 accommodated therein can be moved upward to attach and detach the optical connector (refer to Figure 12). Further, since the output socket 40 accommodated in the upper housing 20 is rotatable relative to the upper housing 20, it is not necessary to rotate the upper housing 20, and the optical connector can be easily attached or detached to the output socket 40.

Further, according to the present embodiment, the upper portion of the output socket 40 accommodated in the lower casing 10 and the upper casing 20 is exposed by the casings, so that the output socket 40 can be directly processed from above the socket housing box 2.

Moreover, according to the present embodiment, the output socket 40 accommodated in the lower casing 10 is not covered by the upper casing 20, so that it is not necessary to move the upper casing 20, and the output socket in the lower casing 10 can be handled more easily. 40.

Hereinabove, the present invention has been described in detail based on the embodiment thereof, but the present invention is not limited to the above embodiment. The present invention can be modified as described below without departing from the gist of the invention.

In the above embodiment, the upper housing 20 is mounted to be rotatable relative to the lower housing 10, and the output receptacle 40 in the upper housing 20 is mounted to be rotatable relative to the upper housing 20, but only Use either of these methods. For example, if the upper housing is attached to be rotatable relative to the lower housing, the output socket in the upper housing can be completely fixed to the upper housing.

When the upper casing is attached to be rotatable relative to the lower casing, a fixing mechanism for maintaining the upper casing in a state of tilting the lower casing may be provided in the storage box. In this case, the tilting state of the frame can be maintained, so that the optical connector can be attached and detached more easily.

Further, the splitter module may be configured to rotate the lower casing. For example, if the lower frame is rotatably attached to the fixing portion including the pedestal portion having the upper surface and the lower surface of the lower casing, the insertion opening of the output socket in the lower casing can be moved upward. It is easy to load and unload the optical connector.

In the above embodiment, the four output sockets 40 are integrated, but the width of the beam splitter module can be further shortened by removing the inner walls of the respective sockets. Needless to say, the elements corresponding to the hook portion 42, the projection portion 43, and the claw portion 44 may be attached to the respective output sockets without integrating the output sockets.

The mechanism for rotatably attaching the output socket to the upper housing or the lower housing is not limited to the above-described hook portion 42. For example, an output socket 40p (see FIG. 15) including a cylindrical shaft member 45 protruding in the width direction may be used, or an output socket 40q including a cylindrical shaft hole 46 formed in the width direction may be used. (Refer to Figure 16). In the case of using the output socket 40p, it is only necessary to provide a shaft hole for inserting the shaft member 45 on the inner wall corresponding to the side surface of the frame body, or in the case of using the output socket 40q, as long as the insertion shaft hole is provided in the inner wall thereof. 46 shaft members can be used.

In the case where the output socket is rotatably attached to the upper housing or the lower housing, a fixing mechanism for maintaining the output receptacle in a state in which the output housing is tilted may be provided in the optical splitter module (accommodating box). In this case, the tilt state of the output socket can be maintained, so that the optical connector can be attached and detached more easily.

In the above embodiment, the four socket housing boxes 2 for accommodating the eight output sockets 40 and the beam splitters S that are divided into 32 equal parts are used, but the number of output sockets accommodated in the storage box and the storage box used therein are used. The number or the type of the spectroscope is not limited to this. For example, a spectroscope module may be configured by combining a storage box similar to the socket housing case 2 and a beam splitter that is divided into eight equal parts. In addition, a splitter module may be configured by combining one storage box 2a (see FIG. 17(a)) in which 16 output sockets are arranged in the lower casing and the upper casing, and a beam splitter which is divided into 32 equal parts. group. In the storage box 2a, the upper frame system is constituted by four housings for accommodating four output sockets, and each of the housings is independently rotatable (see FIG. 17(b)).

In the above-described embodiment, the plurality of output sockets 40 accommodated in the lower casing 10 protrude further forward than the upper casing 20, but whether or not they are so protruded can be arbitrarily determined. Further, in the above embodiment, one of the upper surface 10c of the lower casing 10 and one of the upper surfaces 20a of the upper casing 20 are partially opened. However, whether or not the upper surface of the casing is opened can be arbitrarily determined.

Further, in order to further reduce the installation area of the storage box, the corners of the rear end portions of the storage box may be chamfered to have a curved surface. Thereby, it is possible to reduce the occurrence of disconnection of the optical fiber cord or the optical cable, etc., which is caught by the corner of the storage box.

In the above embodiment, the socket housing case 2 accommodates the optical receptacle, but may house the optical adapter instead of the optical receptacle. For example, the present invention can be applied to a spectroscope module (accommodating case) that accommodates an optical connector that is fitted with an SC connector or the like.
