It is possible to make one 6-core cable for connecting the two. Therefore, wiring between devices can be simplified and wiring work can be facilitated.

  Furthermore, since the modular jack 13 of the splitter device 1 shown in FIG. 2 is replaced with a cable 52 having a modular plug 53 at one end, a cable for connecting to the terminal device can be included in the splitter device 50. Therefore, the user does not have to prepare a cable for connecting the splitter device 50, that is, the connection device and the terminal device.

  FIG. 6 shows a splitter device 60 which is still another embodiment of the present invention. FIG. 6A shows the appearance of the splitter device 60. The splitter device 60 includes a splitter BOX 61, a cable 62, a cable 63, a modular plug 64, and a modular plug 65.

The modular plug 64 is connected to the modular jack of the telephone set 2, and the modular plug 65 is connected to the modular jack of the terminal box integrated door phone base unit 3.

  Six terminals of the modular plug 64 are respectively connected to six core wires of the cable 62, and four terminals of the six terminals of the modular plug 65 are respectively connected to four core wires of the six core wires of the cable 63. The

  FIG. 6B shows the wiring inside the splitter BOX 61. The splitter BOX 61 includes a modular jack 66. The modular jack 66 is a 6-pole modular jack such as RJ-11. Two of the six terminals of the modular jack 66 are connected to the other ends of the two core wires connected to the modular plug 64 at one end of the cable 62 among the six core wires of the cable 62. The remaining four core wires of the six core wires of the cable 62 are respectively connected to the other ends of the four core wires connected to the modular plug 65 at one end of the cable 63 among the six core wires of the cable 63. The modular jack 66 is connected to the telephone line by the connection cable 21 shown in FIG.

  As described above, two of the six terminals of the modular jack 66, that is, the first connecting portion, are the modular plug 64 having six terminals, that is, the cable 62 having the second connecting portion at one end, that is, the first cable. Are connected to the other ends of two of the six core wires, and the remaining four core wires of the six core wires of the cable 62 are connected to one end of the modular plug 65 having six terminals, that is, the third connection portion. Are connected to the other ends of four of the six core wires of the second cable, that is, the telephone line is connected to the first connection portion, and the telephone 2 is connected to the second connection portion. If the terminal BOX-integrated doorphone master unit 3, that is, the terminal device is connected to the third connection portion, the telephone line is connected to the telephone 2 without going through the terminal device. It can be.

  That is, if the splitter BOX 61, that is, the housing of the connection device is installed near the telephone 2, it is possible to eliminate the reciprocation of the telephone line between the rooms. One 6-core cable for connection can be obtained. Therefore, wiring between devices can be simplified and wiring work can be facilitated.

  Further, the modular jack 12 and the modular jack 13 of the splitter apparatus 1 shown in FIG. 2 are replaced with a cable 62 having a modular plug 64 at one end and a cable 63 having a modular plug 65 at one end, respectively. The splitter device 60 can include a first cable to connect to and a second cable to connect to the terminal device. Therefore, the user does not need to prepare a cable for connecting the splitter device 60, that is, the connecting device and the telephone or facsimile device, and a cable for connecting the connecting device and the terminal device.

  In any of the embodiments described above, the splitter device is configured as a device independent of the telephone set 2. However, for example, the splitter apparatus 1 may be incorporated in the telephone set 2. Specifically, the modular jack 11 and the modular jack 13 shown in FIG. In the telephone 2, the terminals 11c and 11d of the modular jack 11 are connected to an internal telephone line signal line, and the set of the terminals 13a and 13f of the modular jack 13 is connected to an internal signal line for one door phone. Then, a set of the terminal 13b and the terminal 13e of the modular jack 13 is connected to an internal signal line for another door phone.

  Thus, since the splitter apparatus 1 is incorporated in the telephone set 2, a cable for connecting the splitter apparatus and the telephone set becomes unnecessary. Therefore, the user can talk with a device such as a door phone simply by connecting the telephone connected to the telephone line to the terminal box integrated doorphone master unit 3, that is, the terminal device.

  In any of the above-described embodiments, the 6-pole modular jack is used as the modular jack. However, an 8-pole modular jack, for example, an RJ-45 modular jack or a modular jack having a larger number of poles may be used. When the 8-pole modular jack is used, the connection cable uses an 8-core modular cable instead of the 6-core modular cable, and the modular plug uses an 8-pole modular plug instead of the 6-pole modular plug.

  Specifically, for example, when the three modular jacks of the splitter apparatus 1 shown in FIG. 2 are replaced with an 8-pole modular jack, two of the eight terminals of the first modular jack are connected to the second modular jack. Each of the eight terminals of the jack is connected to two of the eight terminals by an electrical conductor, for example, a conductor, and the remaining six terminals of the eight terminals of the second modular jack are connected to the eight terminals of the third modular jack. Each of the terminals is connected to each of six terminals with a conductive wire.

  Thus, two terminals of the eight terminals of the first modular jack, that is, the first connection portion are respectively connected to two terminals of the second modular jack, that is, the eight terminals of the second connection portion. The remaining six terminals of the eight terminals of the second modular jack, ie, the second connection portion, are connected by electrical conductors, and the third modular jack, ie, of the eight terminals of the third connection portion, Are connected to the first terminal by connecting the telephone line to the first connection, the telephone 2 to the second connection, and the terminal box integrated doorphone master unit 3, that is, the terminal device. By connecting to the third connection unit, the telephone line can be connected to the telephone 2 without going through the terminal device.

  That is, if the splitter device 1, that is, the connection device is installed near the telephone 2, it is possible to eliminate the round trip of the telephone line between the rooms, and the telephone or the facsimile apparatus and the terminal device are connected with a cable extending between the rooms. Therefore, it is possible to make one 8-core cable. Therefore, wiring between devices can be simplified and wiring work can be facilitated.

  Further, the central two terminals of the eight terminals of the first connection part and the central two terminals of the eight terminals of the second connection part are connected, and the second connection part 8 is connected. Since the six terminals excluding the central two of the two terminals and the six terminals excluding the central two of the eight terminals of the third connecting portion are connected, The position of the terminal for the door phone can be divided. Therefore, since the position of the terminal for telephone and the position of the terminal for door phone can be separated, even if the modular plug is inserted into a modular jack that is not a corresponding modular jack, the signal for telephone and the signal for door phone are connected. Can be prevented.

  Similarly, the modular jack of the splitter apparatus 50 shown in FIG. 5 and the splitter apparatus 60 shown in FIG. 6 can be replaced with an 8-pole modular jack.

  Specifically, the modular jack 54 and the modular jack 55 of the splitter device 50 are replaced with an 8-pole modular jack, the cable 52 is replaced with an 8-core cable, and the modular plug 53 is replaced with an 8-pole modular plug. Two central terminals of the eight terminals of the modular jack 54 are respectively connected to two central terminals of the eight terminals of the modular jack 55 by electric conductors, and the remaining six terminals of the modular jack 55 The terminals are respectively connected to the other ends of six of the eight core wires of the cable 52 having a modular plug 53 having eight terminals at one end. Two terminals in the center of the eight terminals of the modular jack 54 and the modular jack 55 are used for a telephone line.

  In this way, two terminals of the modular jack 54, that is, the eight terminals of the first connection portion, are respectively connected to two terminals of the modular jack 55, that is, the eight terminals of the second connection portion, by electric conductors. The remaining six terminals of the second connection portion are connected, and the other end of the six core wires out of the eight core wires of the modular plug 53 having eight terminals, that is, the cable 52 having the third connection portion at one end. The telephone line is connected to the first connection portion, the telephone is connected to the second connection portion, and the terminal box integrated doorphone master unit 3, that is, the terminal device is connected to the third connection portion. Then, the telephone line can be connected to the telephone without going through the terminal device.

  That is, if the splitter BOX 51, that is, the housing of the connection device is installed near the telephone 2, the telephone line can be prevented from reciprocating between rooms, and the cable extending between the rooms can be connected to the telephone 2 or the facsimile apparatus and the terminal apparatus. It is possible to use one 8-core cable for connecting the cables. Therefore, wiring between devices can be simplified and wiring work can be facilitated. Furthermore, since the cable having the third connection portion at one end is included, the user does not need to prepare a cable for connecting the connection device and the terminal device.

  Further, the modular jack 66 of the splitter device 60 is replaced with an 8-pole modular jack, the cable 62 and the cable 63 are replaced with eight core cables, and the modular plug 64 and the modular plug 65 are replaced with an 8-pole modular plug. The central two terminals of the eight terminals of the modular jack 66 are respectively connected to the other ends of two of the eight core wires of the cable 62 having a modular plug 64 having eight terminals at one end. The remaining six core wires of the eight core wires 62 are respectively connected to the other ends of the six core wires of the eight core wires of the cable 63 having a modular plug 65 having eight terminals at one end. Two of the eight terminals of the modular jack 66 are used for the telephone line.

  As described above, two of the eight terminals of the modular jack 66, that is, the first connection portion, are the modular plug 64 having eight terminals, that is, the cable 62 having the second connection portion at one end, that is, the first cable. The other six core wires of the cable 62 are connected to the other end of each of the eight core wires, and the remaining six core wires of the cable 62 are connected to one end of the modular plug 65 having eight terminals, that is, the third connection portion. Are connected to the other ends of six of the eight core wires of the second cable, that is, the telephone line is connected to the first connection portion, and the telephone 2 is connected to the second connection portion. If the terminal BOX-integrated doorphone master unit 3, that is, the terminal device is connected to the third connection portion, the telephone line is connected to the telephone 2 without going through the terminal device. It can be.

  That is, if the splitter BOX 61, that is, the housing of the connection device is installed near the telephone 2, it is possible to eliminate the reciprocation of the telephone line between the rooms, and the cable extending between the rooms can be connected between the telephone or the facsimile apparatus and the terminal apparatus. One 8-core cable for connection can be obtained. Therefore, wiring between devices can be simplified and wiring work can be facilitated. Further, since the first cable having the second connection portion at one end and the second cable having the third connection portion at one end are included, the user can connect the connection device to the telephone or the facsimile device. In addition, a cable for connecting the connection device and the terminal device may not be prepared.

  As described above, since the modular jack having eight terminals is used, the telephone 2 can talk with three devices through the terminal device. Therefore, the number of devices that can make a call can be increased by one as compared with the case of using a modular jack having six terminals.

  Furthermore, since the modular jack is an RJ-45 8-pole modular jack, it can be connected by a general-purpose 8-core cable. Therefore, an inexpensive cable can be used and cost can be reduced.
