Description

  The present invention relates to a slide structure of a splice unit in which a movable chassis is attached to a fixed chassis via a slide rail and an optical wiring device is placed on a unit that can be pulled out by operating the movable chassis. is there.

Conventionally, the splicing unit 33 is opened and closed by inserting the movable chassis 32 into the fixed chassis 31 and sliding it. The operation of the movable chassis 32 is performed such that a chassis pressing 34 is provided at the front end portion of the fixed chassis 31 so that the movable chassis 32 does not fall out of the fixed chassis 31 when the movable chassis 32 is pulled out. It was regulated. Therefore, the drawer dimension of the unit 33 is limited to the depth dimension of the chassis.

  However, in the conventional slide structure described above, since the unit pull-out size is limited, it is necessary to work in the limited small space at the time of maintenance work after the unit is installed, so the work efficiency is poor. It was.

  In addition, a structure that tilts the unit forward is also used to increase work efficiency, but in this case, the unit may tilt forward while the unit is being pulled out, which may interfere with other loads. The unit was caught and troubled in the pulling out of the unit.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a slide structure of a splice unit that increases the efficiency of installation work and maintenance work of a mounted device, and the structure is a chassis for suppressing the operating range of a movable chassis in a fixed chassis. The slide rail is provided with a first slide hole having a long hole shape for attaching the slide rail to the chassis holder, and a second slide hole for attaching the slide rail to the movable chassis. The slide rail slides through the slide hole, and the movable chassis slides through the second slide hole, so that the unit can be pulled out to the front, and the long hole facing the first slide hole is the long side. The control plate provided with an inclination to the slide rail is used by assembling it on the slide rail, and the front side end of the second slide hole If the control plate is leveled or inclined by the operation of the unit and the unit is stored, the keyhole is covered by the control plate, so the unit does not tilt forward, but the unit is pulled out. In this case, the keyhole is exposed from the control plate, the unit is locked in the keyhole, and the unit can be tilted forward .

In the slide structure of the splice unit according to the present invention, the fixed chassis is provided with a chassis pressing for suppressing the operation range of the movable chassis, and the slide rail has a long hole shape for attaching the sliding rail to the chassis pressing. By providing one slide hole and a second slide hole for attaching the slide rail to the movable chassis, the slide rail slides through the first slide hole, and the movable chassis slides through the second slide hole, The unit is mounted so that the unit can be pulled out to the front, and a control plate with a long hole that is inclined to the long side facing the first slide hole is assembled to the slide rail and used for the second slide A key hole is provided at the front end of the hole, and the control plate is leveled or tilted by the operation of the unit. The keyhole is covered with the control plate, so the unit does not tilt forward.However, when the unit is pulled out, the keyhole is exposed from the control plate and the unit is locked in the keyhole. The movable chassis can be pulled out from the fixed chassis by the size of the slide rail, so that a large space can be secured during work, and work efficiency can be increased. In addition, the splice unit can be slid without interfering with other mounted devices, and the work efficiency can be increased.

  An embodiment of a slide structure of a splice unit according to the present invention will be described with reference to the accompanying drawings of FIGS.

  An optical wiring device is housed in a case 1 to form a unit 2, and this unit 2 is used in a cabinet so that it can be pulled out by a sliding operation.

  The fixed chassis 3 is attached to the cabinet, and the movable chassis 5 is attached to the fixed chassis 3 via the slide rail 4. The slide rail 4 has a first slide hole 6 for attaching the slide rail 4 to the fixed chassis 3 and a second slide hole 7 for attaching the movable chassis 5 to the slide rail 4 with respect to the long side. It is provided in the shape of a slot in parallel. The slide rail 4 is provided with a bent portion 8 in a box shape so that the operation of the movable chassis 5 can be controlled.

  A chassis retainer 9 is attached to the fixed chassis 3 to prevent the slide rail 4 from coming off when the unit 2 is pulled forward. A slide rail 4 is attached to the fixed chassis 3 by inserting seated screws 11 through attachment holes 10 provided in the chassis holder 9 and first slide holes 6 provided in the slide rail 4. Further, the movable chassis 5 is attached to the slide rail 4 using the second slide hole 7. When the unit 2 is pulled out, first, the movable chassis 5 slides by the length of the second slide hole 7 of the slide rail 4. When the unit 2 has reached the tip of the second slide hole 7, the slide rail 4 is now pulled out from the fixed chassis 3. Compared to the slide structure of the conventional unit, the slide rail 4 can be pulled out by the length dimension.

  In order to further improve the workability of the splice unit having the shape described above, the work space can be tilted forward when the unit 2 is pulled out, and the work space can be angled. A key hole 12 is provided at the front end of the second slide hole 7 that joins the movable chassis 5 to the slide rail 4. When the unit 2 is pulled out to the maximum, the seated screw 11 that holds the slide rail 4 to the movable chassis 5 fits into the key hole 12, and the unit 2 is held in a forward tilted state.

  A control plate 13 is incorporated in the slide rail 4 to control the operation of the movable chassis 5 on the slide rail 4. When the control plate 13 is housed in the bent portion 8 of the slide rail 4, the control plate 13 is interlocked with the operation of the slide rail 4. The control plate 13 is provided with a long hole 14 that is not parallel to the long side but is inclined so that the front side is high. The long hole 14 is assembled to face the first slide hole 6 of the slide rail 4. In a state in which the unit 2 is housed in the interior of the cabinet or in a state in which the unit 2 is pulled out by the length of the unit 2, the movable chassis 5 is coupled to the front side of the control plate 13, and the control plate 13 is connected to the slide rail 4. The key hole 12 provided in the second slide hole 7 is covered with the control plate 13 in the lowest position. That is, the seated screw 11 is not fitted into the keyhole 12, and the movable chassis 5 is held horizontally. When the slide rail 4 is pulled forward, the control plate 13 rises along the inclined long hole 14, and finally the keyhole 12 is exposed. The seated screw 11 is fitted into the exposed keyhole 12 to tilt the unit 2 forward.

  If the movable chassis 5 is not fully pulled out, the keyhole 12 is not exposed and the unit 2 does not tilt forward. Since the unit 2 does not tilt forward while the movable chassis 5 is being pulled out, it can be prevented from hitting other mounted devices.

  Since the splice unit can be pulled out to the front, even when many devices are placed in a small space, a work space can be secured on the front surface of the cabinet.
