Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an optical connector for connecting a terminal of an optical cable installed in a building or a premises and another optical cable, for example, an optical cord connected to a device so that it can be easily attached and detached. Is.

2. Description of the Related Art As a conventional optical outlet technology, 10 of catalog JD-180R3 issued by Sumitomo Electric Industries, Ltd.
There is an example of an optical connector called an optical rosette box as shown on the page.

An outline of this product is shown in FIG. 21 in the figure
Is an optical cable, 22 is an optical cable terminal extra length, 23 is a connector side optical connector, 24 is an optical cord, 25 is a cord side optical connector, 26 is a box, and 27 is an optical connector mounting member. A connector-side optical connector 23 is attached in advance to the tips of the two optical fibers taken out from the ends of the optical cable 21 that has been pulled in. The extra length of the optical fiber in the connector is rolled and stored in the box 26 so as to have an appropriate circular shape. In this state, the connector-side optical connector 23 is attached to the optical connector attachment member 27 to form an optical connector. The connection with a device or the like is performed by connecting the cord side connector 25 to the tip of the optical cord 26. A method of connecting by a fusion technique is also used. The connected connection point is covered with a protective cover (not shown) to protect it from the outside.

However, in the structure of the conventional optical connector, there is a problem that it is difficult to attach / detach the connecting portion in the present situation in which the optical-related devices are enriched and the installation positions of many devices are frequently changed and used. was there. Also, when using an optical connector that is becoming popular because of its simple connection work, one of the connectors should be fixed in advance.
When connecting to the other connector by applying a force, there is a problem that the connection loss fluctuates greatly if a force that opens the connection surface is applied.

Also, in the optical connector, as in the case of the conventional electrical connector, there is a demand that it does not protrude from the wall surface or the floor surface and that it does not interfere with the movement of articles or persons and keeps the aesthetic appearance. No optical connector of this could satisfy this.

[0006]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an optical connector which is easy to connect and does not project from a wall surface. It is a thing.

[0007]

SUMMARY OF THE INVENTION The present invention is an optical connector mounted on a wall surface or the like, in which a drawer portion provided with a connector portion is housed in a wall mount portion so as to be drawn out, and the connector portion is provided with an optical cable. Is introduced into the wall or along the wall surface, and the connector portion is configured to be held vertically with the connected connectors joined together.

[0008]

According to the present invention, since the pull-out portion provided with the connector portion is housed in the wall-mounting portion so that it can be pulled out, the connector portion does not project from the wall surface and fluctuations in connection loss due to external contact. Does not occur. It is also beautiful. When connecting a connector from the outside to the connector section, the connector section can be pulled out by pulling out the pull-out section, so that the optical connection can be easily attached and detached. After connecting, you can store the drawer in the wall mount by pushing the drawer in,
Water can be prevented from entering the surface of the optical connector.

Further, since the connector portion is held vertically in a state where the connected connectors are joined, the connector joining surface does not open due to the weight of the connector, and stable transmission characteristics can be obtained.

1 is a perspective view of an embodiment of an optical connector of the present invention, and FIG. 1 (A) shows a state at the time of connection.
(B) shows a state after connection. In the figure, 1 is a drawer part, 2 is a connector part, 3 is a wall surface mounting part, 4 is a wall surface, 5 is a device side connector, 6 is an optical cable, and 7 is a storage space. The drawer portion 1 is provided with a connector portion 2 on its lower surface, is rotatably supported with respect to the wall surface attachment portion 3, and can be in a pulled-out state and a housed state. The wall surface mounting portion 3 also has a box-like shape that doubles as a frame, and is mounted by being embedded in the wall surface 4. The wall surface mounting portion 3 is designed to be large so that a space is formed below when the drawer portion 1 is stored. In this embodiment, the connector portion 2 of the drawer portion 1 is provided with a two-core collective connector. An unillustrated optical cable from the drop cable is introduced into the connector portion 2 along or along the wall surface.

When connecting the device-side connector 5, FIG.
As shown in (A), since the pull-out portion 1 can be pulled out and the connector portion 2 can be projected toward the front, the connection is easy. On the other hand, after the connection, as shown in FIG. 1 (B), the pull-out portion 1 in which the device-side connector 5 is joined to the connector portion 2 is stored in the storage space 7 of the wall surface mounting portion 3 and stored in the wall surface. Does not project outside. Further, since the connector portion 2 is provided on the lower surface of the lead-out portion 1, the optical cable 5 connected to the connector is held vertically, the axis of the connector is vertically aligned, and the joint surface, especially the upper side thereof is opened. There is no such thing and loss fluctuation does not occur. It is also aesthetically pleasing.

FIG. 2 is a perspective view of another embodiment of the optical connector of the present invention, and FIG. 2A shows a state at the time of connection.
(B) shows a state after connection. In the figure, the same parts as those in FIG. Reference numeral 8 is a lid, and 9 is an optical cable introducing portion. In this embodiment, by providing the lid 8 on the optical connector, the surface of the optical connector is covered after the device-side connector 5 is connected, and the connection characteristics of the connector are less likely to be damaged by external force. . By forming a part of the lid body 8 by cutting out the optical cable introducing portion 9, the optical cable can be further stabilized.

FIG. 3 shows a structure of a reinforcing portion used for guiding an optical fiber from a cable in a wall surface to the optical connector side connector of the embodiment of the present invention. 11 in the figure
Is an optical fiber, and 12 is a protective material. As the protective material 12, a coil-shaped material obtained by spirally winding a stainless steel band is used, and the optical fiber 11 is housed therein. In addition to these, metal and plastic materials can be used as the protective material, and an appropriate shape such as a pipe shape can be adopted, but a spring-shaped protective material processed into a spiral shape has excellent bendability and elasticity, Even when the cable is pulled out and stored, the optical cable that comes out of the cable stored in the wall surface is not kinked or bent to be smaller than the allowable bending diameter, which is useful.

[0014]

As is apparent from the above description, in the optical connector of the present invention, since the connector portion does not protrude from the wall surface,
It is aesthetically pleasing and does not cause fluctuations in connection loss due to external contact. In addition, there is no problem such as an article or a person being caught when moving, and there is no problem that the connector is dropped due to these causes. Furthermore, since the connector on the connector side can be pulled out to the front, the optical connection can be easily attached and detached.

When mounted on a wall surface,
Since the connector joint surface enters the space inside the optical connector, it is possible to prevent dust and water from entering the surface of the optical connector. At the time of joining, since the connectors are joined and held in the vertical direction, the connector joining surface does not open due to the weight of the connector, and stable electrical transmission characteristics can be obtained.
