Description

[Detailed explanation of the idea] The present invention relates to an improvement of a branch box.

As shown in the schematic cross-sectional view in Fig. 1 of the attached drawings, a conventional branch box for telephones is constructed by installing a large number of clip terminals 3 in two rows on a wiring board 2 inside a case 1. It is used as a terminal row for wiring and a terminal row for exit construction wiring,
A telephone receptacle connector 4 is arranged on the outer surface of the case 1, and the wrapping terminal 3A of the clip terminal 3 and the solder terminal 4A of the telephone receptacle connector 4 are each wrapped and soldered with a back wiring wire 5. The wires had been properly connected in advance.

In order to branch to a telephone using such a conventional branch box, the installer must connect each coated thin wire of the incoming and outgoing telephone cables one by one to the clip portion 3B of the corresponding clip terminal 3. The branch box is placed on a suitable wall by pushing it in using a tool, and the telephone plug 6 is connected to the telephone receptacle connector 4.

This kind of connection work of the incoming and outgoing cables to the clip terminal 3 is very time-consuming and complicated, and it is also difficult to separate and reconnect the incoming and outgoing cables to the clip terminal 3 after the connection work. Since connections cannot be made easily, it is inconvenient to check the circuit for maintenance.

Moreover, the clip terminal 3 is a relatively large terminal,
Having to use a large number of such terminals not only increases the material cost, but also increases the size of the branch box.
It was difficult to embed it in the wall, so it had to be mounted on the wall.

Furthermore, the wiring between the clip terminal 3 and the telephone receptacle connector 4 is done by wrapping and soldering the wires one by one, which requires a lot of man-hours.

An object of the present invention is to provide a branch connector that eliminates the above-mentioned drawbacks of the conventional branch box, allows easy connection work, is small in size, and is easy to maintain.

Next, the present invention will be described in detail with regard to embodiments of the present invention based on FIGS. 2 and 3 of the accompanying drawings.

FIG. 2 shows a branch connector as an embodiment of the invention with the cover plate removed.

This branching connector is a printed circuit board (here, a
The printed circuit board includes a flexible planar circuit board) 12, an inlet construction wiring receptacle connector 13, an exit construction wiring receptacle connector 14, and a branch equipment connector installed on the printed circuit board 12. A telephone receptacle connector 15 is provided.

Figure 3 shows the printed circuit board 12 and each connector 13.1.
4.15, it is a diagram taken out from the case 11 and seen from the front.

Connections between the respective terminals of the incoming construction wiring receptacle connector 13, the outgoing construction wiring receptacle connector 14, and the telephone receptacle connector 15 are made using the printed circuit board 1.
This is done using printed wiring on 2.

As shown in FIG.
4, a plug connector 16 for connecting an incoming telephone cable and a plug connector 1 for connecting an outgoing telephone cable, respectively.
7 are now combined.

In order to branch to a telephone using such a branch connector, the construction worker must connect each thin wire 1 of the incoming telephone cable 18.
8A to each contact, such as a pressure contact, of the incoming telephone cable connection plug connector 16,
Connect each thin wire 19A of the outgoing telephone cable 19 to each contact of the outgoing telephone cable connection plug connector 17,
Each of the plug connectors 16 and 17 is inserted and coupled to the corresponding receptacle connector 13 and 14, respectively, and then the cover plate 20 is placed over the case 11 and fixed.

At this time, the telephone receptacle connector 15 is exposed through the window 20A of the cover plate 20.

This case 11 is embedded inside a wall surface or the like.

When the telephone plug is coupled to the telephone receptacle connector 15 exposed through the window 20A of the cover plate 20, branching for the telephone is completed.

As described above, according to the present invention, the wiring of the incoming and outgoing cables is done by connecting the uf connectors together, so even after branch wiring work, the incoming and outgoing cables can be easily separated and recombined. Therefore, circuit checks for maintenance can be easily performed.

Furthermore, by installing the input connector and the output connector on the same printed circuit board as the telephone connector, and wiring between them on the printed circuit board, the branch connector can be made very compact. An embedded type is also possible.

The above explanation was for the case where it is used for branching telephones, but the branching connector according to the present invention can also be used for branching for educational equipment, etc., where it is necessary to branch out a large number of slave units from the main line. It is applicable.

Further, although the above description has been made with respect to a device having one telephone connector, it is also possible to provide a plurality of connectors of this type in the same manner.
