Abstract

PURPOSE:To make a change into a different branching state by inserting optical connectors of an optical fiber core which has the optical connectors fitted to both ends between specific adapters in a box body into the adapters, and performing branch wiring. CONSTITUTION:An optical branch and connection box 1 has the rectangular prismatic box body 2 and >=3 cylindrical adapters 4 penetrates a specific surface of the box body 3 and are supported. Branch wiring is performed between specific adapters 4 in the box body 2 by inserting respective optical connectors 5 of optical fiber cores 5 having the optical connectors 5 fitted to both ends are inserted into the adapters 4. This optical branch connection box 1 makes an external connection inserting an optical connector 8 atop an optical cable 7 into a specific adapter 4 outside and connected to the opposite optical connector 5. If a different branch connection needs to be made in this state, the optical connector 5 of an optical fiber core 6 in the box body 2 is extracted from the adapter 4 and inserted into an adapter to be branch-connected, thereby entering a new branch connection state. Consequently, a change into a new branch connection state is easily made.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an optical branch connection box suitable for performing multi-branch connections of optical cables.

(Prior Art) Conventionally, an optical branch connection box for multi-branch connection of optical cables has a structure that allows branch connection only to a specific branch state in advance.

(Problem to be Solved by the Invention) However, in such an optical branching/junction box, if it becomes necessary to change to a different branching state, a new optical branching/junction box matching the state must be manufactured. There was a problem.

An object of the present invention is to provide an optical branching/junction box that can easily be changed to a different branching state.

(Means for Solving the Problems) The structure of the present invention for achieving the above object will be explained with reference to FIGS. 1 to 5 corresponding to the embodiments. Three or more adapters 4 are supported through the shell at different positions, and between the predetermined adapters 4 in the box 2 is an optical fiber core 6 with optical connectors 5 attached to both ends.
The optical connectors 5 are inserted into the adapter 4 to form branched wiring.

(Function) When it is necessary to change to a different branching state, such an optical branching/junction box 1 can connect the optical fiber core 6 in the box 2.
A new branch connection state can be obtained by unplugging the optical connector 5 from the adapter 4 and inserting it into another adapter 4 to which a branch connection is to be made.

(Example) Examples of the present invention will be described below with reference to FIGS. 1 to 5. The optical branching/junction box 1 of this embodiment has a box 2 in the shape of a rectangular parallelepiped.
Three or more (four in the embodiment) cylindrical adapters 4 are supported through a specific surface of the box 2. Within the box 2, branch wiring is established between predetermined adapters 4 by inserting each optical connector 5 of an optical fiber core 6 having optical connectors 5 attached to both ends into the adapters 4. Note that 8 is a lid of the box 2, which is fixed to the box 2 with screws 9.

Such an optical branch/junction box 1 connects the optical cable 7 on the outside thereof.
An external branch connection is made by inserting the optical connector 8 at the tip of the adapter into a specific adapter 4 and connecting it to the other optical connector 5.

In such a situation, if it is necessary to make a different branch connection during use, as shown in FIG. A new branch connection state is obtained by inserting the adapter into the adapter 4 to be used.

(Effects of the Invention) As explained above, in the optical branching/junction box according to the present invention, three or more adapters are supported through the box at different positions, and between predetermined adapters in the box, light is transmitted at both ends. Branch wiring is performed by inserting each optical connector of the optical fiber core wire with a connector attached into the adapter, so when it is necessary to change to a different branching state, the optical connector of the optical fiber core wire inside the box can be connected. By pulling out the adapter from the adapter and inserting it into another adapter to which branch connection is to be made, it is possible to easily change to a new branch connection state. Therefore, according to the present invention, when it is necessary to change the branching state, there is no need to manufacture a new optical branching connection box, and branching and connection can be performed economically and efficiently.
