Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] This invention relates to a housing structure for a connector in a connection terminal box for a cable such as a telephone line.

[Prior Art] In recent years, cables with multiple pairs of core wires, such as telephone lines, have been connected using the Utility Model Application No. 1983, which allows a predetermined number of core wires to be easily connected to each other by instantaneous multi-pair disconnection. A connector (multi-pair connector) as shown in No.-23763 is being used,
The reliability and workability of cable connections have been greatly improved.

As shown in FIG. 16, this connector 1 includes a connector half 1 to which a plurality of core wires 2, 2, . . . are connected, respectively.
9. By connecting the wires 20 to each other, conduction between the core wires 2, 2, . . . at opposing positions is ensured.

A cable connection structure using the above-mentioned connector 1 will be explained by taking as an example the structure shown in FIGS. 17 and 18.

The core wires 2, 2 of each cable 3, 3... are
They are connected by a plurality of connectors 1.1...

And these connectors 1.1... are cables 3, 3
They are arranged concentrically and bundled, and housed in a standard closure 4 formed into a cylindrical shape as a housing part.

[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, etc. are maintained, inspected, cables are changed, etc., all the bindings of these connectors 1, 1, etc. have to be dismantled and the concentric storage form has to be broken, which results in a huge amount of work. The problem was that it was time consuming.

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

In addition, the cylindrical standard closure 4 is not used for connecting aerial cables, etc., and as shown in FIGS.
A connecting terminal box 11 as shown in Figure 0 is used, and the size and shape of this connecting terminal box 11 are determined by the standard, and the cables 3, 3 are connected to the connecting terminal box 1.
Since the connector 1 is inserted near the upper end of both sides 11a and lla of the connector 1,
1. It was not possible to adapt the concentric storage form.

This invention was made in view of the above circumstances, and an object of the present invention is to provide a structure for storing connectors in a connecting terminal box, which allows the connectors to be arranged and stored in the connecting terminal box, and which also has excellent moisture resistance. There is.

[Means for Solving the Problems] A connector storage structure in a connection terminal box according to the first invention is a connector storage structure in a connection terminal box in which a plurality of connectors are stored in an aligned state in the connection terminal box. The connector is housed in a case that has locking pieces formed on both sides and can surround the outer periphery of the connector except for the connection part with the core wire, and the connectors housed in the case are arranged in groups of a predetermined number. are stacked on each other and connected in the stacking direction by connecting members each having a locking hole that can be locked with the locking piece of the case, and each predetermined number of stacked and connected connectors is connected to the connection member. It is characterized in that it is arranged and housed in a lined state next to the excess length of the cable within the terminal box.

In the connector storage structure of the connection terminal box of the second invention, the case of the first invention includes a lower case that can store the connector, and a lid body that can surround the upper surface side of the connector from above the lower case. The device is characterized in that a moisture-proofing agent is filled between the lower case and the lid.

[Operation] According to the connector storage structure in the connection terminal box of the first invention, the connectors housed in the case are stacked and connected in a predetermined number by the connection member, and are aligned in the connection terminal box. Since the connectors are stored, the position and defective location of each connector can be quickly confirmed during maintenance and inspection of the connectors, and work efficiency can be greatly improved.

In addition, by simply engaging the locking hole formed in the connecting piece with the locking piece of the case, it is extremely easy to stack and connect the connectors housed in the case in predetermined numbers, making the storage work much easier. Work efficiency can be greatly improved.

According to the connector housing structure in the connection terminal box of the second invention, the connector is housed in the case consisting of the lower case and the lid body, the outer periphery of the connector is surrounded, and there is a moisture-proof space between the lower case and the lid body. Since it is filled with a chemical agent, the connector stored in the case can be stored in an airtight state.
It becomes possible to significantly improve the moisture resistance of the connector.
