[Problems to be Solved by the Invention] Incidentally, cable connection points using multi-pair connectors have the advantage that wire numbers and continuity checks can be easily identified from the outside due to the core wire arrangement of the connector. As mentioned above, the connectors 1.1... housed inside the cylindrical standard closure 4 are arranged concentrically, so that the 1, 1..., the extra lengths of the connectors 1, 1... and the core wires 2, 2... arranged on the outer circumferential side become a hindrance. For this reason,
Every time connectors 1, 1... are maintained, inspected, cables are changed, etc., all the ties of these connectors 1, 1... must be dismantled and the concentric storage form destroyed, which results in a large amount of work. The problem was that it took a lot of time and effort.

Furthermore, in the concentric connector arrangement, it is difficult to arrange the connectors in an orderly and regular manner, which poses a problem in wire number recognition.

In addition, the cylindrical standard closure 4 is not used for connecting aerial cables, etc., and a connecting terminal box 11 as shown in FIGS. 6 and 7 is used. The size and shape are determined by the standard, and the cable 3.3 or both sides 11a of the connection terminal box 11.

Since the connectors 11a are inserted near the upper end thereof, it has been impossible to accommodate the concentric housing configuration of the connectors 1, 1, . . . as described above.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a structure for storing connectors in a connection terminal box that allows easy maintenance and inspection of each connector.
