For this reason, in order to secure the extra length space of the optical cord, there is a problem that the entire unit body 31 has to be enlarged, and there is a problem that the number of optical cords that can accommodate the extra length is limited and the workability is inferior. there were.
JP 2000-275447 A

  The present invention solves the above-mentioned conventional problems, and can easily add an optical cable later to a splice unit stacked in a rack and pull it in, and even if the unit body is reduced in size, a sufficient amount of optical cable is sufficient. The present invention was made to provide a splice unit that can secure a long space.

  The splice unit of the present invention made to solve the above problems is a splice unit that is stacked in a rack, and includes a cable gripping unit that includes a cable clamp and a tension member clamp for fixing an optical cable to the unit body. This is characterized in that the part is provided so as to be freely drawn out.

  In addition, the unit main body is composed of a fixed part mounted on the rack and a drawer part that is slidable forward and can be pulled out. The rear part of the drawer part interferes with the cable gripping part provided on the rear side of the fixed part. The floor is raised so that it does not rise, and a fusing tray is provided on the top, and a cable guide is provided between the fixed part and the drawer. The cable guide can be stored on the lower surface of the upper part of the step.

In the present invention, the cable gripping part including the cable clamp and the tension member clamp for fixing the optical cable is provided in the unit main body so that the cable gripping part can be pulled out, so that the cable gripping can be performed even when the splice unit is stacked in the rack. The optical cable can be easily added by pulling out the part to the rear side. In addition, an optical cable can be added without attaching another new splice unit to the rack.
Further, when a raised upper part is formed at the rear part of the drawer part and a fusion tray is provided on the upper part, the extra length of the optical cord becomes larger and the extra length can be increased. It is possible to cope with a number of optical codes.

  The present invention will be described in detail below with reference to the drawings.

  FIG. 1 is a perspective view showing a state in which a cable gripping portion is pulled out rearward in the splice unit of the present invention, and FIG. 2 is a perspective view showing a case where a similar fusion tray 7 and a stepped portion described later are omitted. 3 is a front view showing a state in which the splice units of the present invention are stacked on the rack 11, FIG. 4 is a side view thereof, FIG. 5 is a perspective view thereof, and FIG. 7 is a side view showing a state in which the drawer portion 3 is pulled out, FIG. 8 is a perspective view thereof, and FIG. 9 is a perspective view showing a stored state. In the figure, reference numeral 1 denotes a unit main body. In the illustrated case, the unit main body 1 is composed of a fixed portion 2 mounted on a rack and a drawer portion 3 that can slide forward and be pulled out. In the figure, 8 is a surplus length storage section and 12 is an optical cable.

In the present invention, the cable gripping portion 4 including the cable clamp 5 for fixing the optical cable 12 and the tension member clamp 6 is provided at the rear portion of the unit main body 1 so as to be freely drawn out to the rear side.
Thus, since the cable gripping portion 4 has a structure that can be arbitrarily pulled out to the rear side as necessary, the splice units are stacked on the rack 11 and the open portion on the upper surface is closed. However, the cable clamp 5 and the tension member clamp 6 are exposed to the outside by pulling out the cable gripping portion 4 to the rear side, and the optical cable 12 can be easily fixed and added. Further, after the optical cable 12 is added, if the cable gripping portion 4 is returned to the front side, it is housed again in the unit main body 1 so that it does not get in the way. Therefore, the optical cable 12 can be easily added without attaching another new splice unit to the rack as in the prior art. The cable gripping portion 4 has been described as being pulled out to the rear side. However, the cable gripping portion 4 may be pulled out in the lateral direction using a hole in the side surface of the fixing portion 2 of the unit body 1.

    As shown in FIG. 7, the unit main body 1 includes a fixed portion 2 mounted on the rack 11 and a drawer portion 3 that can be slid forward and pulled out. A stepped upper portion 9 is formed so that it does not interfere with the cable gripping portion 4 provided on the rear side, and a fusion tray 7 is provided on the stepped upper portion 9.

  That is, conventionally, the fusion tray 7 has been provided at the center of the drawer 3, so that it is necessary to enlarge the entire unit body in order to secure the extra space for the optical cord, While there was a problem that the number of extra lengths that could be stored was limited (see FIGS. 10 and 11), in the case of FIG. 7, the cable grip provided on the rear side of the fixed portion 2 on the rear portion of the drawer portion 3 A stepped upper portion 9 is formed so as not to interfere with the portion 4, and a fusion tray 7 is provided on the stepped upper portion 9. In other words, according to the present invention, by installing the fusion tray 7 on the raised stepped portion 9, a blank space is secured in the center portion of the drawer portion 3, and the extra length storage portion 8 is formed in this space to form the extra length code. A compact unit structure is achieved by storing the container.

  In addition, a cable guide 10 (indicated by a one-dot chain line) is provided between the fixed portion 2 and the drawer portion 3, and the cable guide 10 can be stored on the lower surface of the stepped portion 9. In this case, Since the cable guide 10 is completely accommodated in the lower surface of the stepped portion 9, it is not necessary to enlarge the unit itself in order to secure the extra space for the cord, and a compact unit structure is possible.

As described above, in the present invention, the cable gripping portion 4 including the cable clamp 5 and the tension member clamp 6 for fixing the optical cable 12 is provided in the unit main body 1 so as to be freely drawn out. If the cable clamp 5 and the tension member clamp 6 are exposed to the outside by pulling out 4, the optical cable 12 can be easily fixed and added.
Further, a stepped upper portion 9 is formed on the rear portion of the drawer portion 3 so as not to interfere with the cable gripping portion 4 provided on the rear side of the fixed portion 2, and a fusion tray is formed on the stepped upper portion 9. 7 is provided, it is possible to secure a blank space in the central portion of the drawer portion 3, and to form a surplus length storage portion 8 in this space to store the surplus length cord. If the guide 10 is stored in the lower surface of the stepped portion 9, a more compact unit structure can be provided.

It is a perspective view which shows embodiment of this invention in case it has a fusing tray. It is a perspective view showing an embodiment of the present invention when a fusion tray is omitted. It is a front view which shows the state which stacked the splice unit of this invention on the rack 11. FIG. FIG. 4 is a side view of FIG. 3. FIG. 4 is a perspective view of FIG. 3.
