FIELD OF THE INVENTION This invention relates to modular cords used in telephones.

[0002]

2. Description of the Related Art Commercially available telephones include analog telephones and two-core digital telephones which mainly use only two voices for two cores.
The input terminals used for line input are constant depending on the type of telephone. The line input terminals of the analog telephone are the 3rd and 4th terminals of the 6-pole modular plug. The line input terminals of the two-core digital telephone are the 2nd and 5th terminals of the 6-pole modular plug. Therefore, depending on the type of telephone, two types of modular cords are used, one is a straight modular cord and the other is a modular cord.

The above-mentioned conventional technique will be described in detail with reference to FIGS. 4 and 5. FIG. 4 is a connection diagram in which an analog telephone and a line input are connected using a conventional 6-pole 4-core straight modular cord. As shown in the figure, the 6-pole 4-core straight modular cord 9 is composed of two 6-pole modular plugs 2 and a 2-pair 4-core cord 11.
The line input terminals of the analog telephone 5 are the 3rd and 4th terminals of the modular jack 7. Line input terminals Nos. 3 and 4 of the modular jack 8 and Nos. 3 and 4 of the modular jack 7 of the analog telephone 5 are connected by a 6-pole 4-core straight modular cord 9. The two cores connected between the second and fifth terminals of the two-pair four-core cord 11 are idle.

FIG. 5 is a connection diagram in which a 2-pin digital telephone and a line input are connected using a conventional 6-pole 4-core twist core modular cord. As shown in the figure, a conventional 6-pole 4-core twist core modular cord 10 is composed of two 6-pole modular plugs 2 and a 2-pair 4-core cord 11. Two
The line input terminals of the core digital telephone 6 are terminals 2 and 5 of the modular jack 12. Line input terminals No. 3 and No. 4 of the modular jack 8 and No. 2 and No. 5 of the modular jack 12 of the two-core digital telephone 6 are connected with a 6-pole 4-core modular cord 10. In addition, each pair core of the two-pair four-core cord 11 is twisted once. Also, the two cores connected to the second and fifth terminals of the 6-pole modular plug on the line input side of the 2-pair 4-core cord 11 are idle.

[0005]

[Problems to be solved by the invention] However, the conventional 6 poles 4
There are two types of core modular cords, one is a straight modular cord and the other is a modular cord depending on the type of telephone, and there is a problem that wiring and adjustment take time and work efficiency is poor.

The present invention has been made in view of the above-mentioned problems, and conventionally, two types of 6-pole 4-core modular cords, which are a straight modular cord and a hineri modular cord, are required for analog telephones or 2-core cords. The purpose is to provide a modular code that can be shared by both digital telephones.

[0007]

In order to solve the above-mentioned problems, a telephone terminal multi-two-core modular cord according to the present invention has a six-pole modular plug 2 attached to each end of a pair of two-core cords 3 and has 6 poles. The 2nd terminal and the 3rd terminal of the pole modular plug 2 are connected with the 1st core of the 1 pair 2 core cord 3 and the 4th and 5th terminals of the 6 pole modular plugs 2 are the 1 pair 2 core cords. It is characterized in that it is connected by the other one core of No. 3.

[0008]

[Function] Attach a 6-pole modular plug to each end of a pair of 2-core cord. The 2nd terminal and the 3rd terminal of this 6-pole modular plug are connected by one core of the one pair two-core cord to short-circuit them. Similarly, 4 of this 6-pole modular plug
Connect the No. 5 and No. 5 terminals with another pair of 1-pair 2-core cord and short-circuit them. In the terminal multi-core two-core modular cord for a telephone having such a configuration, the 2nd and 3rd terminals of both 6-pole modular plugs are electrically connected to each other, and the 4th and 5th terminals are also electrically connected to each other. Further, the line input is input from terminals 3 and 4 of one modular plug. Therefore,
This telephone terminal multi-core 2 modular cord can be shared by an analog telephone having line input terminals 3 and 4, and a 2-core digital telephone having line input terminals 2 and 5.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a terminal multi-two-core modular cord of the present invention. In the figure, reference numeral 1 is a terminal multi 2-core modular cord of the present invention, and two 6-pole modular plugs 2
And one pair of two-core cord 3. The 2nd and 3rd terminals of each 6-pole modular plug 2 are connected and short-circuited by one core of a pair of two-core cords. Also, the 4th and 5th terminals of each 6-pole modular plug 2 are connected and short-circuited with the other 1-core of the paired 2-core cord.

FIG. 2 shows an example of use of the terminal multi two-core modular cord of the present invention. The line input terminals of the analog telephone 5 are the 3rd and 4th terminals of the modular jack 7. As shown in the figure, the line input terminals No. 3 and No. 4 of the modular jack 8 and the modular jacks No. 3 and No. 4 of the analog telephone 5 are connected by the terminal multi 2-core modular cord 1.

FIG. 3 shows an example of use of the terminal multi two-core modular cord of the present invention. The line input terminals of the two-core digital telephone 6 are terminals 2 and 5 of the modular jack 12. As shown, modular jack 8
Line input terminals 3 and 4 and 2-core digital telephone 6
No. 2 and No. 5 of the modular jack 12 are connected by a telephone terminal multi-core 2-core modular cord 1.

[0012]

As described above, in the terminal multi-core 2-core modular cord for telephones according to the present invention, the 6-pole modular plugs 2 are attached to both ends of the 1-pair 2-core cord 3, respectively. The 2nd terminal and the 3rd terminal are connected with the 1 core of the 1 pair 2 core cord 3 and the 4th terminal and the 5th terminal of the 6 pole modular plugs 2 are the other 1 of the 1 pair 2 core cord 3. Since it is connected with a core, it is possible to use an analog telephone and 2
It is possible to share and wire the terminal multi-two-core modular cord for the telephone without being aware of the core digital telephone, and wiring and adjustment are facilitated, and work efficiency is dramatically improved. Further, the number of types of modular cords is reduced, and the conventional 4-core cord is changed to 2-core cord, which has many advantages in terms of material management and economy.
