DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an optical fiber core storage case with a connector for housing a connection portion of an optical fiber core connector by a connector with an appropriate extra length.

[0002]

2. Description of the Related Art In general, an optical fiber core storage case has a structure in which an optical fiber core is stored in a loop shape inside a wall formed around a bottom plate. When storing an optical fiber with a connector attached at the end, with the connector connected to the other end, collect the connector of the optical fiber near the wall on the back (or front) side of the storage case. A connector connection section storage zone for storing the connector is provided.

When an optical fiber core with a connector is stored in a storage case, not all the optical fiber cores are stored in a state of being connected to a counterpart by a connector, and the connector is not connected to the counterpart (in the future). There may be an optical fiber core (awaiting connection). Such an optical fiber core is stored in a storage case with the connector being covered with a cap.

[0004]

The connector connection section storage zone of the storage case holds the optical fiber core wires on both sides of the connector connection section and stabilizes the connector connection section. In such a connector connection section storage zone,
When an optical fiber core having a connector that is not connected to the other party is stored, the connector is held by only one optical fiber core, so that the position is not stable and may be damaged by vibration or the like.

[0005] In addition, if a connector connected to the other party and a connector not connected to the other party are mixed in the connector connection portion storage zone, there is a problem that it is difficult to perform a later connection work or the like. Further, when the connector is covered with a cap, the connector becomes slightly larger than when the connector is naked, so that the connector connection portion storage zone must be enlarged in order to store the connector, resulting in an increase in the size of the storage case. There is also a problem.

An object of the present invention is to provide an optical fiber core storage case with a connector that solves the above-mentioned problems.

[0007]

According to the present invention, a front wall, a rear wall and left and right side walls are integrally formed around a bottom plate, and an optical fiber core is provided near the rear wall or the front wall. In the optical fiber core storage case provided with a connector connection part storage zone for storing the connection part by the connector, a plurality of rising pieces having an optical fiber core wire protruding prevention piece at the upper end are provided substantially in the center of the upper surface of the bottom plate. And a partition wall is formed on both sides of the rising piece arrangement portion, with a space where the connector attached to the tip of the optical fiber core can be stored with a cap, and an optical fiber core is formed on the partition wall. A slit which can be inserted is formed.

[0008]

With this configuration, when there is an optical fiber core having a connector with a cap that is not connected to the other party, the optical fiber core near the connector is inserted between the slit of the partition wall and the rising piece, and the cap is inserted. Can be stored between the partition wall and the rising piece arrangement portion. In this stored state, the optical fiber core wire near the connector is held by the rising piece having the protrusion preventing piece at the upper end, so that the position of the connector is stabilized.

Further, the connector connected to the other party is stored separately in the connector connection section storage zone, and the connector not connected to the other party is stored separately between the partition wall and the rising piece arrangement section, so that later connection work or the like is performed. It will be easier. Furthermore, since the connector connection section storage zone only needs to store the connector connected to the other party, the required space is smaller than in the case where the connector with the cap is stored together, and the storage case can be downsized.

[0010]

Embodiments of the present invention will be described below in detail with reference to the drawings. 1 to 3 show an embodiment of the present invention. The optical fiber core storage case 11 includes a case body 13 and a cover plate 15. Note that the cover plate 15 is provided as needed and may be omitted in some cases.

The case body 13 includes a bottom plate 17 and a front wall 1.
9a, a back wall 19b, left and right side walls 19c and 19d, and a guide wall 21 of the optical fiber 1 are integrally formed. Optical fiber core wire introduction portions 23 are formed on the left and right side walls 19c and 19d. Left and right side walls 19
Projection preventing pieces 25 are formed at the upper ends of c and 19d, the upper end of the guide wall 21, and the like to prevent the optical fiber core wire 1 from jumping out.

In the vicinity of the back wall 19b of the case body 13,
A connector connection part storage zone 27 for storing a connection part of the optical fiber core 1 by the connector 3 is provided. In the connector connection part storage zone 27, a number of rising pieces 29 holding the optical fiber cores 1 on both sides of the connection part by the connector 3 are arranged at a predetermined pitch. The cover plate 15 is attached to the case main body 13 by a hinge 31 so as to be openable and closable.

The storage case 11 is characterized in that a plurality of rising pieces 33 having an optical fiber core wire protrusion preventing piece 34 (see FIG. 3) at the upper end are arranged in the front-rear direction substantially at the center of the upper surface of the bottom plate 17. A partition wall 35 is formed on both sides of the arrangement portion of the rising pieces 33, and a slit 37 into which the optical fiber 1 can be inserted is formed in the partition wall 35. A space is provided between the rising piece 33 arrangement portion and the partition wall 35 so that the connector 3 attached to the tip of the optical fiber core 1 can be stored with the cap 5 covered.

[0014]

The optical fiber core storage case of the present invention is
With the above configuration, if there is an optical fiber core having a connector with a cap that is not connected to the other party, the optical fiber core is stably stored in a location different from the connector connection part storage zone. can do. As a result, there is an advantage that the protection of the optical fiber core becomes more reliable, and the later connection work or the like becomes easier. Further, since it is not necessary to store the connector with the cap in the connector connection portion storage zone, the size of the connector connection portion storage zone can be reduced, and therefore, there is an advantage that the storage case can be downsized.
