Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a housing structure of a connector in a connection terminal box of a cable such as a telephone line.

[Related Art] In recent years, in connection with a cable having a multi-paired cable such as a telephone line, a real number of cables which can easily connect a predetermined number of cables without any instantaneous interruption of many pairs have been proposed. A connector (multi-pair connector) as shown in -23763 is being used, and the reliability and workability of cable connection have been greatly improved.

As shown in FIG. 16, this connector 1 is formed by connecting connector halves 19, 20 to each of which a plurality of cores 2, 2,.
2, 2,... Are connected.

The connection structure of the cable using the connector 1 is
Description will be made by taking the example shown in FIGS. 17 and 18 as an example.

The cores 2, 2,... Of the respective cables 3, 3 are connected by a plurality of connectors 1, 1,. The connectors 1, 1,... Are arranged concentrically and bundled with the cables 3, 3, and are housed in a cylindrical standard closure 4 as a housing.

[Problems to be Solved by the Invention] By the way, at the connection point of the cable by the multi-pair connector, there is an advantage that the wire number identification and the continuity check can be easily performed from the outside by the core wire arrangement of the connector. As described above, the connectors 1, 1... Housed inside the cylindrical standard closure 4 are arranged concentrically and housed, respectively. When performing maintenance / inspection of 1 ..., the extra length of the connectors 1, 1 ... and the core wires 2, 2 ... arranged on the outer peripheral side will be in the way. For this reason, these connectors 1
There was a problem that it was necessary to disassemble all the shackles of 1 ... to break up the concentric storage form, which required a lot of trouble. Further, in the concentric connector arrangement, it is difficult to arrange connectors at first glance with order and regularity.

The connection of an imaginary cable or the like does not use the cylindrical standard closure 4 described above, and is not shown in FIGS.
As shown in the figure, a connection terminal box 11 is used, and the size and shape of the connection terminal box 11 are determined according to the standard, and the cables 3, 3 are connected to both sides 1 of the connection terminal box 11.
Since the connectors 1a, 11a are inserted near the upper ends, the above-described concentric housing of the connectors 1, 1,... Cannot be adapted.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a connector housing structure in a connection terminal box in which a connector is aligned and housed in a connection terminal box and has excellent moisture resistance. I have.

Means for Solving the Problems The housing structure of the connector in the connection terminal box of the first invention is a housing structure of the connector in the connection terminal box in which a plurality of connectors are housed in an aligned state in the connection terminal box. Wherein the connector is housed in a case in which locking pieces are formed on both sides and which can surround the outer periphery of the connector except for a connection portion with a core wire of the connector, wherein the connector is housed in a predetermined number of cases. Are connected in the stacking direction by a connecting member formed with a locking hole capable of locking with the locking piece of the case, and a predetermined number of the stacked and connected connectors are connected to the connection member. It is characterized in that it is arranged and housed in the terminal box so as to be aligned with the extra length of the cable.

The housing structure of the connector in the connection terminal box of the second invention is a lower case in which the case of the first invention can house the connector, and a lid body capable of surrounding the upper surface side of the connector from above the lower case. Wherein the space between the lower case and the lid is filled with a moisture-proofing agent.

[Action] According to the housing structure of the connector in the connection terminal box of the first invention, the connectors housed in the case are piled up and connected by a predetermined number by the connection member, and are aligned in the connection terminal box. Since the connectors are stored, the positions and defective portions of the respective connectors can be promptly confirmed at the time of maintenance / inspection of the connectors, and the workability can be greatly improved.

In addition, by simply engaging the locking holes formed in the connecting pieces with the locking pieces of the case, the connectors housed in the case can be extremely easily stacked and connected in a predetermined number of cases. Work efficiency can be greatly improved.

According to the housing structure of the connector in the connection terminal box of the second invention, the connector is housed in the case composed of the lower case and the lid, the outer periphery thereof is surrounded, and the moisture proof is provided between the lower case and the lid. Since the agent is filled, the connector housed in the case can be housed in an airtight state, and the moisture-proof property of the connector can be greatly improved.
