The redundant part 3a of the optical fiber cable 3 is housed in a curled state into a housing, there by, the kinking of the redundant part 3a of the optical fiber cable 3 is prevented and the minimum bending radius can be secured.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an optical information outlet.

[0002]

2. Description of the Related Art FIG. 4 is a conceptual diagram showing a conventional example of an optical information outlet.

An optical information outlet 10 as a terminal of the optical information outlet system is connected to one end of an optical fiber cable 3 while being incorporated in the housing 1 fixed at a predetermined position such as a road or a river. Optical connector 2. The optical connector 2 is an information transmitting / receiving device (for example, a portable terminal or a notebook computer) 5
Can be joined with the optical connector 4. The other end of the optical fiber cable 3 is connected to an optical connector of another information transmitting / receiving device or another optical information outlet, and by connecting the optical connectors, information between the information transmitting / receiving device 5 and the other information transmitting / receiving device is connected. Can be transmitted and received.

[0004]

When the conventional optical information outlet 10 shown in FIG. 4 is used, it is necessary to exchange information while the information transmitting / receiving device 5 is close to the optical information outlet 10. is there.

However, if the information transmitting / receiving device 5 is used at a place remote from the optical information outlet 10, it is impossible to use the information transmitting / receiving device 5 as it is, and as shown in FIG. Since the optical information outlet 10 and the information transmitting / receiving device 5 must be connected by the cable 6 or by using the radios 7a and 7b, the trouble of carrying the extension optical fiber cable 6 and the radios 7a and 7b is reduced. I'll take it. In particular, since the wireless devices 7a and 7b require power, there is a problem that the system becomes complicated. FIG. 5 is a conceptual diagram showing another conventional example of an optical information outlet.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above problems and to provide an optical information outlet which can be connected to an information transmitting / receiving device at a remote place without using an extension cable or a radio.

[0007]

SUMMARY OF THE INVENTION In order to achieve the above object, an optical information outlet according to the present invention is provided with a housing fixed at a predetermined position such as along a road or a river, and incorporated into the housing and retracted from the outside. An optical information outlet having an optical connector connected to one end of a connected optical fiber cable, wherein the optical connector is detachably held in the housing and the optical fiber cable is located at a position distant from the housing. It has a redundant portion that can be extended up to.

[0008] In addition to the above configuration, in the optical information outlet of the present invention, it is preferable that the redundant portion of the optical fiber cable is housed in a housing in a curled shape.

According to the present invention, when connecting to an information transmitting / receiving device located away from the housing of the optical information outlet, the optical connector is disconnected from the optical information outlet and the optical fiber cable is pulled to the information transmitting / receiving device. Then, the optical connector connected to one end of the optical fiber cable may be connected to the optical connector of the information transmitting / receiving device.
When the redundant portion of the optical fiber cable is accommodated in the housing in a curled shape, the optical fiber cable is prevented from being entangled, and the minimum bending diameter can be ensured.

[0010]

Embodiments of the present invention will be described below in detail with reference to the accompanying drawings.

FIG. 1 is a conceptual diagram showing an embodiment of the optical information outlet of the present invention. FIG. 2 shows a state where the optical connector is accommodated in the optical information outlet shown in FIG.
FIG. 2 is a diagram showing a state where a door of the optical information outlet shown in FIG. 1 is opened. Note that the same members as those in the conventional example shown in FIGS.

An optical information outlet 20 shown in FIG. 2 includes a housing 1 fixed at a predetermined position such as a road or a river,
An optical connector 2 connected to one end of an optical fiber cable 3 while being incorporated in the housing 1. The optical connector 2 is detachably held by the housing 1, and the optical fiber cable 3 is separated from the housing 1. It has a redundant portion 3a that can be extended to the information transmitting / receiving device 5 at a position.

The optical connector 2 is housed inside the door 9 of the housing 1 but is not fixed to the door 9. The redundant portion 3a of the optical fiber cable 3 is housed in a curl shape.

When connecting the optical connector 4 of the information transmitting / receiving device 5 at a position distant from the optical information outlet 20 to the optical connector 2 of the optical information outlet 20, the door 9 of the housing 1 is closed as shown in FIG. The optical connector 2 is opened, the optical connector 2 is removed from the optical information outlet 20, the redundant portion 3a of the optical fiber cable 3 is pulled to the information transmitting and receiving device 5, and the optical connector 2 connected to one end of the optical fiber cable 3 is connected to the optical transmitting and receiving device 5. By connecting to the connector 4, the optical connector 4 of the information transmitting / receiving device 5 and the optical connector 2 of the optical information outlet 20 can be connected as shown in FIG.

The redundant section 3a of the optical fiber cable 3
Is accommodated in the housing 1 in a curl shape,
The redundant portion 3a of the optical fiber cable 3 is prevented from being entangled, and the minimum bending diameter can be secured.

The shape of the housing 1 may be any of a cube, a triangular prism, a cylinder and the like. In addition, the structure of the housing 1 may be a structure to be stored in a wall surface of a building or the like or in a basement. Furthermore, the shape of the redundant portion 3a of the optical fiber cable 3 housed in the housing 1 of the optical information outlet 20 is not limited to the curl shape, but may be wound on a pulley or a reel.

In the above, information can be transmitted and received at a position distant from the optical information outlet, which is an information terminal, without using an extension optical cable, a wireless device, or the like.
