[Detailed description of the invention] The present invention relates to a fiber terminal arrangement device for a multi-core cable, and is particularly suitable for use when arranging one end of a large number of core wires based on the arrangement order of the other ends. The present invention relates to a fiber terminal arrangement device for a multi-core cable.

When wiring within a device or between devices in a computer or the like, it is necessary to connect one group of terminals to be connected to the other group of terminals in a predetermined relative relationship.

In order to make such a connection, in the past, a connecting device was used in which the ends of each core wire of the cable were connected in an arrangement order based on the above-mentioned relative relationship to a large number of connection terminals of a connector connected to both terminal groups. is used.

In this connection tool, when connecting the end of each core wire to the connector, a worker identifies the core wire based on the color of the core wire sheathing and the symbol such as a dot mark attached to the sheath. As shown in FIG. 1, the ends of each core wire 1a of a multi-core cable 1 are arranged in a predetermined order and held together with adhesive tape T, etc., and then connected to the connector. .

However, when the number of core wires is tens or more, it becomes complicated to identify the color or code of each core wire, which may lead to incorrect arrangement or connection. However, problems arise in that a connection test between both connectors is required.

The present invention was developed in view of the above circumstances, and its purpose is to ensure that the terminals of each core wire are arranged in a predetermined order even when there are many core wires in a multi-core cable.
