フフィバ心線の接続が行えて好適である。[Prior art] A composite cable in which an optical fiber core is built into a Fi wire is constructed by attaching an optical connector to the tip of the optical fiber core led out from the end of the wire, and attaching a wire extension clamp to the end of the wire. Attachment: An optical connector is built into the cylindrical portion of this wire extension clamp to form a terminal portion, and an arling wire is connected to the tip of the wire extension clamp to be installed on a steel tower. In such composite cables, the wires are stretched due to the tension during wire stretching, resulting in insufficient length of the optical fiber core wire and tension being applied to the optical fiber core wire. The optical fiber core wire led out is provided with an extra part of a predetermined length,
We were trying to deal with the extension of the electric wires. After the wire extension is completed, the electric wires are connected to each other using jumper wires while being held to the steel tower by the holding means, and the optical fiber core wires are connected to each other using optical connectors. It is preferable to connect the optical fibers using a pre-attached optical connector in this way, since the optical fibers can be easily connected in the air.

易い問題点があった。[Problems to be Solved by the Invention] However, in the terminal portion of a composite cable having such a structure, after connecting the optical fiber core wires with an optical connector, the connecting portion is housed in a junction box to prevent external forces such as tension. They had to be protected from water and rainwater, which resulted in increased on-site work and poor workability. In addition, in such an 8Ii structure, since the optical fiber is drawn into the interior from the end of the electric wire during wire extension work, there is a problem that the optical fiber is easily damaged at the edge of the end of the electric wire.

In a terminal portion 12 of a composite cable 1 in which an optical fiber core 3 is built into an electric wire 2, an optical connector 4 is attached to the end of the optical fiber core 3 led out from the end of the electric wire 2. A connector housing 5 for accommodating the optical connector 4 and the exposed portion of the optical fiber core 3 adjacent thereto is attached, and the optical fiber core 3 in the connector housing 5 is filled in the connector housing 5.

る。[Function] If the optical fiber core 13 is fixed to the end of the electric wire 2 via the connector housing 5 with the filling fixing agent 6 in this way,
Electricity when the line is extended! Is it still light even if 12 is extended? The RI electric wire 3 is no longer drawn into the RI electric wire 2. Therefore, there is no need to provide an extra part of the optical fiber core 3 outside the end of the electric wire 2,
The terminal portion 12 does not have to be elongated. Furthermore, since the optical fiber core 3 is not drawn into the electric wire 2 during the wire drawing, it is possible to prevent the optical fiber core 13 from being damaged by the electric wire 111 portion during the wire drawing. After the wire is stretched, the wire clamp 10 is removed to separate the connector housings 5 and 112, and then a predetermined length of the wire 2 is peeled off to free the optical fiber core 3 and connect it to the optical fiber core 1j13. Due to the tension that was acting on the optical fiber core Fi 13, the electric wire 2
As a result, the optical fiber core m3 can be easily released from the tension. Furthermore, since the optical connector 4 is housed in the connector housing 5, it is protected from external forces and the tension is borne by the connector housing 5 side. Therefore, having such a connector housing 5 eliminates the need for a connection box and facilitates connection work on site.

Since it is fixed via the connector housing and the filling fixing agent, it is possible to prevent the optical fiber core wire from being drawn into the wire even if the wire is stretched during wire extension. Therefore, it is not necessary to provide an extra length of the optical fiber core outside the end of the electric wire, it is possible to prevent the terminal portion from becoming elongated, and it is possible to prevent deterioration of the workability of wire extension. Further, according to the present invention, since the optical fiber is not drawn into the Ti wire during the drawing, the optical fiber is not pulled into the Ti wire during the drawing. It is possible to prevent IHO at the la section. Moreover, in the present invention, since the tip of the N wire and the connector housing are connected by a wire clamping tool, the l1il can be easily separated from the connector housing after the wire has been extended. By cutting the wire, an opening is created that facilitates the work of drawing the optical fiber core into the wire using the tension generated during drawing and releasing the tension. Furthermore, in the present invention, since the optical connector is housed in the connector housing, it can be protected from external forces, and the tension can be borne by the connector housing, which safely protects the optical connector and the optical fibers near it. be able to.
